Book Review: ‘The Longest Con’ by Joe Conason. 

Some of my more attentive readers may have noticed that in the last couple of years I’ve been reading and reviewing quite a few books that deal with how our country got into its current political mess, about how the people of the United States became so divided and distrustful of each other. The return of Donald Trump to a second term as President has only confirmed in me the idea that our experiment in democracy and a multi-racial, multi-cultural society has taken a wrong turn somewhere. In the United States today it just seems to me that the credo of ‘Every man for himself’ is dominant and that money, as much and as quickly as possible, is the only measure of success.

‘The Longest Con’ by journalist Joe Conason is another such book and in many ways the worst. I don’t mean that the book is bad, far from it. No, what I mean is that ‘The Longest Con’ details some of the worst kinds of human behavior that have been committed over the last eighty or so years, all in the name of good, wholesome, conservative American values. ‘The Longest Con’ is the story of ‘How Grifters, Swindlers and Frauds Hijacked American Conservatism’ to quote the book’s subtitle.

I guess that pretty much sums it up. A Swindler is a thief who uses lies instead of a gun to rob you. (Credit: YouTube)

The author Mr. Conason begins by first describing what could be termed the ‘type specimen’ of the kind of fake ‘ultra-American’ fraudster that he claims has taken over conservatism and the Republican party, Roy Cohn. Cohn is best known as the lawyer who worked with Senator Joseph McCarthy to discover hidden communists inside the US State Department. Publicly Cohn portrayed himself as a patriotic American trying to protect his country from ‘red infiltrators’. In reality however Cohn and McCarthy never succeeded in finding a single communist. They just used false accusations, hate mongering and scare-tactics to ruin the reputations of a lot of decent people, both in and out of government, all while lining their own pockets at taxpayer’s expense.

Roy Cohn (r) first became a public figure as a hatchet man for Senator Joe McCarthy (l). The two of them destroyed the reputations on numerous innocent people by just making accusations without any evidence. Sounds a lot like what’s going on in this country today! (Credit: Free Speech Center MTSU)

After McCarthy’s downfall Cohn returned to private practice in New York where he continued his heavy handed methods of always attacking, using any kind of dirt against opponents, even if it wasn’t true, all while claiming he was the one being treated unfairly. Towards the end of his life Cohn would become a mentor in bad behavior to a young Donald Trump, who has surpassed his teacher in climbing to the top by whatever means was necessary.

One other facet of Cohn’s life is worth mentioning because it is a trait that many other frauds within the conservative movement have also been guilty of. One of the most vicious attacks that Cohn used against his enemies was to accuse them of sexual depravity, especially homosexuality. The irony is that it was Cohn himself who was gay. Following in Cohn’s lead since then many other conservative rabble-rousers have charged liberals with sexual misconduct only to be later revealed as the true perverts.

Another right-wing Republican who raged against Gays while concealing his own sexual crimes was Dennis Hastert whom the republicans made Speaker of the House. (Credit: Open Secrets)

‘The Longest Con’ then goes on to detail the many, many scams and frauds that have been perpetrated by right wing organizations whether they be political, like the John Birch Society or Evangelical Christian such as the Praise The Lord TV network. The list of individuals and groups who have swindled the American public in the name of conservatism is almost endless. ‘The Longest Con’ covers them all right up to the recent ‘Tea Party’ movement and of course our Fraudster in Chief Donald Trump.

John Birch was an agent of the Office of Strategic Services (OSS) the forerunner of the CIA who was killed in China during WW2, no one knows how. The John Birch Society considered him to be the first casualty of WW3 and that’s how they got their name. Like McCarthy and Cohn, the Birchers accused anyone and everyone while never providing any evidence, and made a lot of money doing it! (Credit: Financial Times)

Throughout ‘The Longest Con’ the techniques that the fraudsters use are described at length. Mostly the swindler sets up a fake charity, so that they can claim tax-exempt status. Then solicitations are sent out to conservatives around the country, either by mail or on the TV or nowadays through the Internet. So far it sounds just like any charity doesn’t it, but what happens then is that nearly all of the money taken in goes to salaries or expenses for the fraudster and their friends and family. Whatever money remains then goes for further fundraising while next to nothing goes to any actual charitable work.

Legitimate charities get most of the money they raise by direct appeals to the public, often by mail. The same is true for the fraudsters.

The worst part is that since these cons claim to be charities, law enforcement is often reluctant to investigate, let alone prosecute them. Even when the fraud is revealed the perpetrator(s) are generally only sentenced to a small fine and are soon free to start yet another con job.

There are thousands of fraudulent charities out there trying to take your money by simply lying to you. Learn how to protect yourself from such scammers. (Credit: Community Tax)

By the end of ‘The Longest Con’ the endless list of grifts and swindles actually becomes depressing, it’s becomes hard to imagine that so many people could be so corrupt. That’s one problem with ‘The Longest Con’ although I suppose it’s unfair to blame Mr. Conason for all of the con men we have in this country.

An Argument is one thing but today it seems as though all we do is yell and curse one another! (Credit: M-L-M Mayhem)

Another problem is that quite often Mr. Conason becomes a bit too polemic in his descriptions of the bad guys, often referring to them as “ostentatiously pious” or describing their actions as “deep fakery” for example. The use of such invective may be warranted but still it takes away from the objectivity in ‘The Longest Con’. So I do recommend ‘The Longest Con’, our country has gotten itself in a sorry state and Mr. Conason does a very good job of describing how we got here, and the sort of people who are pushing us ever further into the gutter.  

Astronomy News for February 2025: The latest results from the James Webb Space Telescope. 

It seems as though every time that astronomers build a new instrument, one that’s bigger, or more precise or one that looks at the sky above in a different way the discoveries made by that instrument challenge if not actually break existing theories about the Universe. It all started when Galileo first pointed his primitive telescope skyward and saw the moons of Jupiter, spots on the Sun, the phases of Venus and saw that the Milky Way was actually composed of thousands, millions of stars. As optical telescopes got bigger and bigger they saw more things like nebula and star clusters. Then, when astronomers added spectrographs to their telescopes they were able to discover what elements the stars were made of.

In the 20th century radio telescopes discovered objects like pulsars and quasars while X-ray telescopes discovered black holes. With each new technological advance in the astronomer’s instruments came a better understanding of the Universe even if that meant tossing aside some older, well established ideas.

Today we build large arrays of radio telescopes in order to get an even clearer view of what lies out there! (Credit: PrimalLuceLab)

Observations by the James Webb Space Telescope (JWST) began to astound astronomers within weeks of its beginning operation in 2022. You see, the JWST was designed primarily to study the early Universe, around a billion years after the Big Bang. If you’re wondering how a telescope can see into the past remember that since the speed of light is a finite 300,000 kilometers per second all you have to do is look at something billions of light years away and you’ll be seeing it as it was billions of years ago.

In operation less than three years the James Webb Space Telescope (JWST) has already shaken up many of our theories about the early Universe. (Credit: European Space Agency)

But you better have a big telescope, and you better put that telescope in space so it can just stare at the object you’re observing for hours or days or longer to gather enough light. Oh, and since the entire Universe is expanding the Doppler effect is going to cause that light from billions of years ago to be shifted to longer wavelengths, you’ll have to build your telescope to see in the infrared. That means you’ll have to get it away from any heat sources like the Sun and Earth, which is why the JWST was placed at the Lagrangian (L1) point in the Earth’s shadow but a million kilometers from our planet.

The five Lagrangian points are the only exact solutions to the ‘Three Body Problem’ in celestial mechanics. Only L4 and L5 are really stable but the JWST is located at Earth’s L1 point where it only requires occasional adjustments to its orbit. (Credit: Australian Space Academy)

So as I said, JWST was primarily designed to study the Universe only a billion or so years after the big bang and those were some of the first images it took. Astronomers were interested in that period because they theorized that was the time that the first stars began to shine, that the first galaxies began to form. (See my post of 6 July 2024.)

Just a few years ago this was our best idea of the evolution of the Universe. After the big bang cooled off there was a period called the dark ages that lasted until about 400 million years after the big bang when the first stars began to shine. The first galaxies formed not long after that. The JWST has already forced us to make some changes to that timetable. (Credit: NASA Science)

One question that it was hoped that the JWST could answer dealt with the supermassive black holes that astronomers are now convinced lie at the heart of every galaxy, at least every big one. Simply put, the question was, which came first? Did galaxies form supermassive black holes in their centers, or do supermassive black holes form galaxies around them? Obviously any theory of how galaxies form needs to know that.

What the JWST did in fact see when it made its first observations were a large number of what astronomers named ‘Little Red Dots’, that is small but rather bright galaxies with a reddish glow to them. By their brightness the red dots appeared to contain millions of bright stars and some of them were found to have existed less than half a billion years after the big bang, a time so early that according to most theories of galaxy formation no such well developed galaxies should exist. That was why there were so many news articles about JWST having ‘Broken Cosmology’.

That was about two years ago and since then the JWST has both discovered a lot more ‘Little Red Dots’ and made much more detailed and precise measurements of some of them. Now a team of astronomers headed by Dale Kocevski of Colby College has announced results of their survey of the red dots at a conference of the American Astronomical Society that was held in Maryland the second week in January.

The recent 245th meeting of the American Astronomical Society must have been a fun party!!!! (Credit: Threads)

What the astronomers found was that the better observations of the red dots all showed light signatures indicating that much of their light came from hot gasses spiraling into a growing black hole. So the reason the red dots were so bright wasn’t because they had millions of stars but because they had the beginnings of a Quasar, a feeding black hole in their center. The JWST observations don’t break current theories of cosmology but those theories are certainly going to have to be modified.

Six Quasars as seen in an optical telescope. Today we know that these objects are galaxies with a feeding supermassive black hole at their center that is giving off so much light that it is outshining the entire galaxy around it. (Credit: Britannica)

The case isn’t closed yet however, because about a billion years after the big bang all of the red dots seem to disappear. Dr. Kocevski and the other astronomers in the team think that, as the black hole forms a galaxy around it will start to take on the appearance of a more ‘normal’ active galactic nuclei (AGN).

Quasars are often also referred to as ‘Active Galactic Nuclei’ (AGN). The question for astronomers is how did the ‘Little Red Dots’ evolve into AGN? (Credit: Medium)

So it seems that the JWST has given us the answer to our question about which came first: galaxies or the supermassive black holes inside them. The ‘Little Red Dots’ are black holes that serve as the seeds of galaxy formation. But like every other scientific answer this one breeds another question; where do the black holes that form the ‘Little Red Dots’ come from?

Climate Change Review for the year 2024; The Hottest year ever recorded for the World. 

The year 2024 has been over for more than a month now and although scientists are still evaluating all of the Climate measurements that they obtained during the past year the broad outline of Global Warming’s impact on our planet is clear. The year 2024 was simply the hottest year ever recorded in human history, erasing the record set just the year before in 2023. In fact the ten hottest years ever recorded have all occurred in the last ten years.

And this was BEFORE 2024 was declared the hottest year ever! So really the 11 hottest years ever recorded have been the last 11 years! (Credit: Climate Central)

For the world as a whole the temperature in 2024 was measured as being 1.6ºC above pre-industrial levels, that baseline being as measured from the years 1850 to 1900. The world’s temperature not only exceeded the previous record from 2023 but did so but did so by more than a tenth of a degree, +0.12ºC, an enormous jump. Indeed, over the last two years temperatures worldwide have been so hot that they have surpassed most models of global warming, leading some climate scientists to fear that global warming is actually accelerating. A few statistics that illustrate just how fast the temperatures are climbing worldwide in 2024 are that for every cold temperature record that was set fifty record high temperature we set. At the same time six of the world’s seven continents recorded their hottest years ever, only Asia bucked the trend recording its second hottest year ever.

That figure of 1.6ºC of course breaks the target figure of limiting global temperature to 1.5ºC above pre-industrial levels that was set back in the Paris accords of 2015. Now that goal was intended to be an average over a decade or more so we haven’t failed yet. However the last two years have averaged over the 1.5ºC goal and we’re still not really doing anything to control global warming, to reduce if not eliminate the amount of green house gasses that we are dumping into the atmosphere.

In the nine years since the great majority of the world’s nations agreed to the Paris accords virtually nothing has actually been accomplished. (Credit: Yale MacMillian Center, Yale University)

In fact we are actually pumping more greenhouse gasses into the sky. Measurements of CO2 levels at the weather station at the Mauna Loa Observatory in Hawaii, indicate that in 2024 CO2 in the atmosphere increased by 3.58 parts per million, that’s the largest increase since records began there in 1958. Not all of the increase has come from burning fossil fuels; a lot is coming from all of the wildfires that are increasing in number and intensity. The concentration of CO2 in the atmosphere is now 50% higher than it was back in 1900 and most models of climate change agree that another such large increase as happened in 2024 will eliminate all hope of keeping below the Paris agreed 1.5ºC limit.

In fact, we are still actually increasing the amount of greenhouse gasses being emitted into the atmosphere, with no end in sight! (Credit: Carbon Brief)

So much for the temperature measurements for 2024, the effect of all that heat on climate disasters throughout the world is not hard to find. There were the extreme droughts in Italy, southern Africa, the Amazon and the American Southwest as well as the excessive rainfall in Ireland, Spain, Southern India and the Philippines. Add to that the severe storms that ravaged both the Atlantic and Pacific oceans like Hurricanes Helene and Milton along with Typhoon Gaemi in the Pacific. Of course there were heat waves around the planet such as those in the American Southwest, Central Europe and China. In the United States the number of ‘billion dollar’ disasters’ in 2024 was 27, an unprecedented number as was the total dollar figure for the damage 182.7 billion.

The billion dollar disasters for the US in 2024. The total value came to more than 180 billion dollars along with more than 500 lives. And it’s only going to get worse! (Credit: Climate.gov)

Between the years 1980 and 2010 the yearly number of weather disasters averaged about 8 but over the last five years it has ballooned to more than 20, an exponential growth rate. It’s worth pointing out that if the trend continues, the destruction caused by extreme weather will in a few years generate a considerable stress on the American economy. That possibility is causing a growing fear within the insurance industry, which has to pay their costumers for any damage to property by the weather.

In the last six years two million homes have been refused insurance because of the risk generated by climate change. Of course, most of those homes are in states like California and Florida that experience the worst effects of global warming but even in my home state of Pennsylvania it has begun. (Credit: New York Times)

Because of that many insurance companies are now refusing to accept customers in ‘high risk’ areas of the country such as in wildfire areas in California or hurricane prone parts of Florida. However remember that much of the damage done by hurricane Helene occurred in the western mountains of North Carolina, an area generally considered safe from severe weather. So in just a few years the question will be, is any part of our country, any part of the world safe from severe weather. 

Hurricane Helene slammed into Florida as a Cat 4 causing destruction all the way up even into North Carolina. (Credit: ABC45)

Of course it’s not just property that’s harmed by severe weather, there’s a cost in human lives as well. For example, in those ‘billion dollar’ disasters mentioned above 418 Americans were directly killed, 225 by hurricane Helene alone. Now, I just said directly caused by weather disasters, that figure doesn’t include all of the people whose lives were shortened by extreme heat, such as the 113 consecutive days above 100ºF in Phoenix Arizona which led to a record 645 heat related deaths. Heat waves in other parts of the world, where air conditioning is rare led to many more thousands of deaths. And again, if the trend of exponential growth in temperature continues those death figures will also grow exponentially.

I simply can’t imagine 113 straight days of over 100 degrees F (37.8 degrees C). And look at by how much it broke the old record of 76! Phoenix broke all kinds of heat records in 2024. (Credit: Fox Weather)

I’m going to end here, but the litany of extreme weather events is so large that I could go on and on. There is some good news, since the strong El Nino event that began in 2023 has now turned into a La Nina most climate models suggest that 2025 will not be as hot as either 2024 or 2023. Most experts expect this year to only be the third hottest year ever recorded. Of course that makes you wonder how bad the next El Nino will be when it comes.

Climatologists had hoped that 2025 would be a little bit cooler than 2024, it sure hasn’t started that way!!! (Credit: Facebook)

So long as we continue to burn fossil fuels the world will simply get hotter and hotter, that’s all there is to it.

Space News for February 2025: Unmanned Probes make some News. 

It seems as though my last several space news posts have all been about manned space flight, either to the International Space Station or beyond, back to the Moon. I don’t want to give the impression that our unmanned probes haven’t been making any discoveries or advancing our ability to explore the solar system so in this post I’ll be discussing the latest news about unmanned space exploration and I’ll begin with the big news from the Parker Solar Probe.

Artist’s impression of the Parker Solar Probe making the closest ever approach to the Sun of any man made object. The thermal shield that protected Parker from the Sun’s heat is on the left facing the Sun. (Credit: Science Friday)

Launched in 2018 the Parker Solar Probe is named for Eugene Parker, a NASA astrophysicist who back in the 1950s predicted the existence of the Solar Wind. The solar wind is the never creasing stream of sub-atomic particles that flow outward from the Sun for about 20 billion kilometers creating a bubble around our solar system. See my post of 18 December 2019. During its six-year mission so far the Parker probe has crept ever closer to the Sun using gravity boosts from both the Earth and Venus to alter its orbit.

In its last close flyby in 2023 Parker set records for both proximity to the Sun, at a distance of 6.2 million kilometers as well as fastest speed ever attained by a human built object, 635, 266 kilometers per hour. Remember the Sun’s gravitational field is so much stronger than Earth’s that a space probe traveling close to it has to travel at an enormous speed in order to not get sucked in!

The velocity of an object orbiting a planet or star increases as the object gets closer to the planet or star. (Credit: YouTube)

But on the 24th of December 2024 Parker was scheduled to break both of those records with an even closer approach to the Sun at a distance of only 6.1 million kilometers and reaching a speed of 692,000 kilometers per hour. Getting so close to the Sun is obviously a dangerous maneuver not only because of the enormous heat, estimated at 980º C, but also because of the energy of the particles in the solar wind which can easily destroy sensitive electronics.

Sometimes the Sun erupts in massive solar flares but even when the Sun is quiet it is still constantly emitting super-heated plasma of enormous energy that could prove deadly to the electronics on a space probe. (Credit: The Wonder of Science)

To protect the spacecraft’s instruments from the worst of Sun’s energy Parker has an 11.5 cm thick carbon composite shield that is kept facing the Sun. Nevertheless as the probe makes its closest approach to the Sun the Space Agency knew that they would lose all radio contact with it, NASA did not know that Parker had survived until two days later on December 26th.

Even after receiving the signal that Parker was in good shape NASA still had to wait until New Year’s Day before the spacecraft could begin transmitting back the data it had collected at its closest approach to the Sun. Meanwhile Parker is scheduled to make two more flybys of our Sun, on March 22nd and June 19th of 2025 although neither will be quite as close as the one on December 24th.

Parker isn’t finished with the Sun just yet. The probe will make two more close approaches to our star this year! (Credit: NASA Science)

Meanwhile, not too far away the European Space Agency’s (ESA) BepiColombo probe made its fifth flyby of the planet Mercury, the closest planet to the Sun on the first of December 2024. Like Parker, BepiColombo is using the gravity of Mercury in order to change its trajectory so that in 2026 the spacecraft can go into a permanent orbit around the solar system’s smallest planet. Even though the encounter on the first was only a flyby the scientists at the ESA still used the occasion to check out their instruments by making detailed observations of Mercury, particularly the probe’s infrared spectrograph. 

Actually two space probes in one BepiColombo consists of the Mercury Planetary Orbiter (l) and the Mercury Magnetosphere Orbiter (r). (Credit: Space.com)

Surprisingly, BepiColombo is actually two spacecraft in one. Once in orbit around Mercury BepiColombo will split into two distinct probes. One is the Mercury Planetary Orbiter (MPO) and the other is the Mercury Magnetospheric Orbiter (MMO). Both probes will conduct different observations of the planet. Like the Parker Solar Probe, BepiColombo promises to reward us with many new discoveries in the near future.

The planet Mercury is much closer to Earth than Jupiter but because it is so close to the Sun it is more difficult to get to, so we actually know less about it. BepiColombo will hopefully teach us a great deal more. (Credit: Phys.org)

Finally I have some sad news to report, the Ingenuity helicopter, which was carried to the planet Mars aboard the Perseverance rover and which became the first human built craft to fly on another planet, see my post of 1 May 2021, crashed on its 72nd flight. Now bear in mind that Ingenuity was really just a test vehicle, intended only to see if flight of any kind was even possible in Mar’s thin atmosphere. The original NASA plan was for Ingenuity to only take five flights, tests that would be observed by Perseverance. That the little helicopter would succeed in making 72 flights over a three-year period and cover over 16 kilometers was beyond the wildest hopes of the engineers at the Jet Propulsion Labouratory who designed and built the aircraft.

The Ingenuity helicopter on Mars was the first ever man made aircraft to take flight on another planet. Originally planned to take five experimental flights the little helicopter that could made rose above the Martian surface 72 times before finally crashing. (Credit: Popular Mechanics)

Now NASA has released a report detailing what they think happened to Ingenuity, although since the accident happened over 100 million kilometers from Earth no one can visit the crash site to do a proper investigation to be certain. The trouble seemed to begin on Ingenuity’s 70th flight when the helicopter was flying over an area of flat terrain with few features. Because the ground below had so few landmarks it caused Ingenuity’s visual navigation system to become confused. The same problem occurred on the next flight, in fact the navigation system ordered an emergency landing, one that turned out to be a hard landing, a landing that NASA thinks damaged at least one of the helicopter’s blades. Ingenuity’s 72nd and final flight was intended to be just a short test to see whether any damage had been sustained but the helicopter quickly crashed, breaking off both of its rotors about midway.

When a Lear Jet recently crashed in NE Philadelphia member of the National Transportation Safety Board (NTSB) were quickly on site investigating what had happened. When Ingenuity crashed on Mars it obviously wasn’t possible for investigators to visit the site so the engineers at NASA had to figure out what happened based on the data the little aircraft had sent back to Earth. (Credit: YouTube)

Ingenuity may no longer be flying but the tiny probe is still working, acting now as a weather station on the Martial surface. And because Ingenuity was so successful NASA is now planning on a new helicopter to explore Mars. The proposed aircraft has been given the name Mars Chopper and it is a six-engine drone like helicopter that will be about the size of an SUV. Mars Chopper will carry an array of instruments to enable it to explore the Red Planet but whether it will operate in cooperation with a rover or autonomously is still to be decided.

In either case Mars Chopper will join the Parker Solar Probe and BepiColombo and all of the unmanned spacecraft that humans beings have sent into outer space to explore our solar system.

Archaeology News for February 2025:  Two Ancient Sites that tell us a great deal about how People lived Thousands of Years Ago.

Starting about ten thousand years ago we humans first began to both cultivate crops and domesticate herd animals. These twin achievements allowed our ancestors to end their nomadic, hunter-gatherer lifestyle and settle down into more permanent sites, villages, towns and eventually cities.

The Hunter-Gatherer lifestyle wasn’t quite as exciting, or as dangerous as this but life was hard for our ancestors more than 10,000 years ago. (Credit: Students of History)

This change from temporary housing in caves or portable huts to long-term structures obviously is a great boon to present day archaeologists. Think about it, a cave where an extended family lived for a few months out of the year certainly won’t contain as much archaeological evidence for an excavator to find as would a cluster of dwellings where many families lived for decades or longer. Nevertheless the details of exactly when and how that change from wanderers to homesteaders took place are still fuzzy, which is why a great deal of the efforts of archaeologists today are geared towards the study of how humans built those first urban areas.

The first villages appeared in Mesopotamia about 10,000 years ago and probably looked something like this. Mud brick homes of a single room each with the work of farming and domestic animals happening right where the people lived. (Credit: Q-files)

As I mentioned above one of the advancements that enabled the first villages and towns to be built was domesticating animals that could be herded like sheep or goats or even reindeer in the north. Now the raising and handling of such large groups of animals requires not only pastures for grazing but also corrals for confining them when it becomes time for sheering, branding, slaughtering or even just counting how many of them you have.

Today we still use corrals whenever we want to keep animals in one place. (Credit: Carri-Lite Corrals)

A recent study by archaeologists at Tel Aviv University and Ben Gurion University of the Negev in Israel has upended long held ideas about a late Stone-Age, early Bronz Age, 4-5 thousand year old mysterious site in the Golan Heights known as the ‘Gilgal Refaim’, which is Hebrew for the ‘Wheel of Giants’. For decades now the 100-meter in diameter site had been interpreted as an astronomical observatory like the famous Stonehenge in England. Indeed the site is often referred to as the ‘Wheel Stonehenge’.

The Wheel of Giants, Gilgal Refaim in Hebrew as it appears in the Golan Heights. Until recently it was thought that the neolithic people who built this site used it as a calendar but new studies have shown that 4-5,000 year ago the site had no alignment to the solstices or equinoxes. Instead it appears to have been used as a corral for rounding up domestic, or possibly wild animals. (Credit: Israel Bardugo Photography)

The new study however took into account the way that Plate Tectonics, working at a slow rate of 8-15 mm per year has over the last 4-5 thousand years moved and even rotated the wheel. So looking at the way that the wheel was orientated back in the Neolithic the archaeologists found that there were no alignments to any celestial objects or events like solstices or equinoxes that would be important to a newly agricultural society. Instead the researchers maintain that Gilgal Refaim was a corral, a place that shepherds or goatherds could bring their flocks. The researchers also surveyed the surrounding area within 30km of the site and found other, smaller examples of such stone wheels averaging 20m in diameter. So perhaps Gilgal Refaim is simply the largest of a whole class of structures in the area used to concentrate livestock.

At the same time the archaeologists also recognize that structures like corrals can often serve as locations where people gather and interact. Remember the first rodeos were just people having fun at corrals while working with their livestock. So there is every possibility that Gilgal Refaim could have been used as a gathering place for nearby clans, either for religious of social events.

If you think about it the first Rodeos were just people having fun while working with domestic animals at a corral! Certainly people back in the Neolithic did much the same. (Credit: Canadian Horse Journal)

Another way in which the lives of human beings changed as they began to live in settled communities is the spread of communicable diseases. Think about it, a small group of nomads, say 12-15 people, who wander from one place to another with the seasons as different resources become available will probably only encounter other such groups three, maybe four times a year. Those are hardly the conditions that would allow an infectious disease to spread rapidly.

We have ample evidence that hunter gatherer groups were quite small, rarely more than a dozen people in all and those groups came in contact with other such groups only occasionally. (Credit: Wikipedia)

When humans started living in larger communities of hundreds or thousands of people however infectious organisms could multiply more easily, allowing the evolution of more diseases that could inflict our species. Indeed there is considerable DNA evidence that illnesses like salmonella, tuberculosis and even the bubonic plague all began to infect humans during the Neolithic period, the time of the first villages.

Cities, with big crowds of people are the perfect environment for diseases to spread. (Credit: South China Morning Post)

Now there is also evidence that humans began to adapt to these new, potential epidemic conditions by adopting a policy of ‘social distancing’ familiar to all of us thanks to Covid-19. A team of researchers from the University of Tennessee, Cambridge University, Durham University and Texas A&M have studied the patterns of settlement during the Neolithic ‘Trypillia’ culture of eastern Ukraine. Their results have been published in the ‘Journal of the Royal Society Interface’. During the late Stone Age this area contained a number of proto-towns or even proto-cities that have been well studied by archaeologists.

The researchers focused on one settlement known today as Nebelivka, which possessed thousands of wooden dwellings that were identified as being arranged in concentric patterns and clustered in pie shaped neighborhoods. Using computer programs designed to both study the spread of diseases as well as model urban planning to minimize that spread the team discovered that the inhabitants of Nebelivka were well aware of the hygienic benefits of ‘social distancing’. “This clustered layout is known by epidemiologists to be a good configuration to contain disease outbreaks.” According to Lead Author Alex Bentley of the University of Tennessee. “This suggests and helps explain the curious layout of the world’s first urban areas. It would have protected residents from emerging diseases of the time.”

The team also conducted a more detailed simulation of what would occur in Nebelivka if a food borne illness such as salmonella was to break out there. Carrying out millions of computer simulations what they discovered was that the pie shaped clustering of houses in Nebelivka helped to reduce the spread of such diseases.

Even today the food borne illness Salmonella causes a huge number of people to get sick. Part of the reason for this is the concentration of people living in cities. (Credit: Harvard Health)

The study’s result may also help to explain why the residents of Nebelivka are known to have burned down their dwellings on a regular basis and replaced them with new wooden houses. Fire has long been used as a means of fighting infectious disease.

There is much evidence throughout Eastern Europe of Neolithic People burning their homes on a regular basis. Archaeologists aren’t certain but it seems likely they did this in order to prevent the spread of diseases. (Credit: Daybreaks Devotions)

What both of these two studies show is that the people of the Neolithic period were every bit as smart as we are. That they used what technology they had to solve the problems that they faced and occasionally they developed new technology that they passed on. We are the inheritors of their knowledge and wisdom, we should be a little more grateful.

Book Review: ‘Triumph of the Yuppies’ by Tom McGrath. 

As the 1960s came to an end and the Vietnam War withered to its foregone conclusion the ‘Hippies’, those radicalized college students who protested everything and everyone now faced a terrible reality; they had to get jobs and earn a living. Unlike their parents, who had normally lived a quiet life working for a single company and bought a home in the suburbs, they wanted something more exciting. They wanted a fast paced career where they could be a big success, and they wanted to move back into the cities where there were more and different kinds of people and just more things to do.

These ‘Baby Boomers’ would, in the decade of the 1980s create a new demographic called the ‘Young Urban Professionals’ or ‘Yuppies’. The new book by author Tom McGrath, ‘Triumph of the Yuppies’ details how during the 1980s this small percentage of the American population came to completely change our country, and not for the better. Now not every baby boomer became a yuppie, for the most part yuppies were the college educated boomers who used what they’d learned to transform the US economy from one based on manufacturing to one based on service and finance. As an example of how quickly this metamorphosis took place in 1960 there were only 4,500 Master’s degrees in Business Administration (MBAs) handed out by US colleges and Universities but by 1976 there were over fifty thousand every year and that number would continue to grow throughout the 1980s.

Remember in 1960 only 4500 MBA degrees were awarded by all the colleges in the US. How much damage has been caused by the enormous growth of professionals whose only training is in getting every penny of profit that they can! (Credit: eLerners.com)

In ‘Triumph of the Yuppies’ author McGrath follows the lives of many of the participants in that transformation, people like Peter Ueberroth who organized the 1984 LA Olympics, Bruce Springsteen whose song ‘Born in the USA’ became an anthem for a generation or Marissa Piesman whose ‘the Yuppie Cookbook’ helped popularize the name. These are only a few of the dozens of people who are mentioned because of their influence on the decade.

The 1980s also saw tremendous growth in the Celebrity Industry, allowing ordinary people to follow the wonderful lives of people better than they were! (Credit: ebay)

Three individuals stand out however as examples of their time. Jerry Rubin the 60s radical who in the late 70s decided he wanted to be rich along with Michael Milken, the investment wizard who turned risky and low valued ‘Junk Bonds’ into a multi-billion dollar business. The third was Jack Welch, the CEO of General Electric (GE) who kept his stockholders happy by squeezing every penny he could out of two of the most famous companies in the US, and in the process destroyed one and while leaving the other a shell of its former self.

Once the most radical of Hippies starting in the late 70s Jerry Rubin became a high priest of the new religion ‘Money’! (Credit: The History Channel)

It was these individuals, along with thousands of others who actually accomplished the ‘Reagan Revolution’ a revolution whose real architect was the economist Milton Friedman. With the relaxation of regulations on banking and other financial industries the brand new MBAs began a series of ‘Leveraged Buy Outs’ and ‘Hostile Take Overs’ all of which made money for those in on the deal.

Michael Milken, on the other hand, was always devoted to the god Mammon! (Credit: Investopedia)

Meanwhile, those who weren’t MBAs or Yuppies of one variety or another saw jobs being sent overseas to counties with lower wage workers. McGrath even quotes Walter Mondale’s acceptance speech in the 1984 Democratic Convention “To those companies that send our jobs overseas, my message is: We need those jobs here at home.” So all the while that the dealmakers were lining their pockets the gap between rich and poor continued to grow.

In 1984 Walter Mondale (r) got clobbered by Ronald Reagan (l). But everything that Mondale warned us about has pretty much come true. We haven’t done much better ever since! (Credit: YouTube)

In their rush to make money as quickly as possible to keep shareholders happy the management at American companies cut back on long term investments in order to turn short term profits. One case in point is particularly tragic, RCA the leading US electronics manufacturer made the deliberate decision not to invest $200 million dollars in the technology and assembly lines necessary to build the new Video Cassette Recorders that everybody wanted. Instead RCA spent $1.2 billion buying a small financial bank so that management could show an immediate profit. That’s why today Sony and Sanyo and Panasonic own the household electronics industry while RCA no longer exists.

The Radio Corporation of America (RCA) was once a leader in technology and industry. today it no longer exists. It is a victim of the ‘profit today instead of investing in tomorrow’ strategy. (Credit: Reason Magazine)

In ‘Triumph of the Yuppies’ author McGrath tells a hundred such stories, he relates the details of deals and mergers that, in hindsight, have led to many of the problems our country faces today. At the same time McGrath also reminds us of the culture of the 80s, the decade of excess. The fictional TV shows ‘Dallas’ and ‘Dynasty’ are mentioned along with the early reality shows like ‘Lifestyles of the Rich and Famous’. Other aspects of yuppie life are mentioned as well such as the exercise craze that Jane Fonda made a bundle on and gourmet food. In all ‘Triumph of the Yuppies’ does a great job of bringing the 80s back to life.

The 80s were a time of excess in all things, even exercise. Jane Fonda went from opposing Vietnam to helping everyone stay trim and fit, and made a bundle doing so! (Credit: Amazon)

And that’s the problem with ‘Triumph of the Yuppies’ it’s all tales with no context, no analysis. McGrath never manages to describe how the counter-culture of the 60s grew into the excesses of the 80s, and he never discusses what do we do now to try to fix our economy, our political system, our country. So while ‘Triumph of the Yuppies’ does detail where our country went wrong there are no solutions, no mention of a way forward.

Income inequality is a growing problem in our country today. Can we solve it, and can we solve our environmental problems without solving it? (Credit: Othering and Belonging Institute)

Nevertheless, I do give ‘Triumph of the Yuppies’ a thump’s up because it is really entertaining. Time and time again you will find yourself smiling at the antics of the selfish, looking out for number one bastards who truly believed that ‘Greed is Good!’

Are Nuclear Chemists on the verge of Manufacturing a new Element for the first time in 23 years? 

We all remember the Periodic Table of the Elements from our High School Science classes. You’ll remember that one of the things we were taught was that Uranium, element number 92, was the heaviest element that occurred naturally, all of the higher number elements had been manufactured in a labouratory using an ‘Atom Smasher’ or similar technology. The atomic number you’ll recall is simply the number of positively charged protons in the nucleus of any atom.

Of course, you all remember the Periodic Table of the Elements. You may not believe it but this table really does pack a huge amount of information about the chemical elements in a convenient form! (Credit: PubChem)

The first artificial element was manufactured in 1940 and was actually number 94 Plutonium, which was created by forcing alpha particles into a nucleus of Uranium. You may remember that alpha particles are actually the nucleus of Helium, element number 2, so adding element 2 to element 92 gets you element 94. In the years shortly after World War 2 many new elements were created by physicists. Starting in the 1960s however the pace began to slow as it became more and more difficult to produce heavier elements.

The reason for why making heavier elements became more difficult is actually the same as the reason why there are no naturally occurring elements beyond Uranium, radioactivity. In fact every element beyond Bismuth, element 83 is radioactive and will eventually decay into some lighter element. What’s actually going on is that the positively charged protons repel each other, in electricity it’s opposites charges that attract while similar charges repel after all. When you get more than about 80 protons in a nucleus even the nuclear glue, the so-called ‘Strong Force’ has trouble keeping the nucleus together.

This image has an empty alt attribute; its file name is unnamed.gif
When the nucleus of an atom becomes ‘too big’ meaning that it has too many protons the electric repulsive force trying to push the nucleus apart becomes stronger than the nuclear force keeping it together. The atom will eventually decay by either emitting an alpha particle (upper right) or a beta particle (upper left) or a gamma ray (lower left). (Credit: HyperPhysics Concepts)

Take Uranium with 92 protons for example, it has what’s called a half-life of about 4.5 billion years. What that means is, if you had 100 atoms of Uranium and waited 4.5 billion years half of those atoms would have decayed into some lighter element, only 50 would be left as Uranium. It’s a curious fact that since our Earth is also about 4.5 billion years old that means that today our planet only has half of the Uranium it originally had.

 Many other elements have shorter half-lives than Uranium, Radium for example has a half life of only 1620 years making it very radioactive and therefore very dangerous. Plutonium, the first artificial element has a half life of about 80 million years, which still makes it kinda dangerous.

When first discovered Radium was thought to be a miracle element. The fact that it glowed continuously all be itself should have told someone that any chemical that energetic was dangerous, but it wasn’t until many people got radiation poisoning that scientists realized how deadly it was. (Credit: Scientific Scarsdalian)

Anyway, the elements beyond Plutonium have very short half-lives, hours, minutes, even seconds and by the time you get to the heaviest element so far, Oganesson at number 118 it has a half life of only milliseconds. Indeed, Oganesson’s half life is so short that it was probably created a couple of years before its existence could be verified. The atoms just didn’t last long enough for the chemical checks to be completed that would make certain that it had been created.

The heaviest element manufactured so far is Oganesson, number 118. Notice how the element’s appearance is predicted. Not enough of Oganesson has been made so far for anyone to be able to see it! (Credit: Science Notes and Projects)

The rules of Quantum Mechanics are strange and arcane however and the theoretical physicists who try to understand the nucleus have for several decades now been predicting that an ‘island of stability’ should exist from about element 120 to 126. Elements in this span are calculated to last for minutes if not hours or perhaps even longer, if only we could get there.

According to the complex mathematics of Quantum Mechanics the Protons and Neutrons in the nucleus arrange themselves in shells. A shell that is filled is more stable than an unfilled shell making some nuclei longer lasting than others. It is predicted that elements 120-126 will be more stable so nuclear chemists are trying to produce those elements. (Credit: Open MedScience)

Now experimentalists at Lawrence Berkeley National Labouratory may have found the right technique. What they have succeeded in doing is to develop a beam of titanium nuclei, atoms of element 22 that have been completely stripped of their electrons. Using them to bombard atoms of Plutonium, element 94 the scientists have succeeded in producing the superheavy element Livermorium, number 116. The key factor here is that a pure beam of titanium nuclei something never before achieved with an element so high on the periodic table.

A step by step outline of the experiment performed at Lawrence Berkeley that used titanium nuclei to produce Livermorium, element 116. Titanium is the heaviest nuclei to be used as a projectile in an ‘Atom Smasher’ so this experiment is a big step forward. (Credit: Gizmodo)

What the researchers at Lawrence Berkeley Labouratory plan to do now is to replace the Plutonium target with the element Californium, number 98 in order to produce element 120 and thereby reach the shore of that elusive island of stability. They expect that effort to take several years, Californium is both hard to get and hard to work with, but these scientists are the best in the world at handling superheavy elements.

Everything in our world, including our own bodies is made of such atoms and nuclei, by creating these new elements physicists learn more about both the particles making up the nucleus and the forces that keep it together, or force it apart.

Two Stories from Nature that Illustrate just how similar the Behavior of Animals is to our Own. 

There was a time when it all seemed so simple, the behavior of we humans was based on reason and moral judgment while that of the animals was purely based on instinct, a rather egotistic point of view to be sure. In fact, ever since we humans began to actually look at the way animals do behave, we’ve been surprised at how often animal behavior resembles our own.

Like ourselves Chimpanzees are now known to use a variety of tools for different jobs. (Credit: AnimalWise)

Many animals use tools! Many communicate with each other using a variety of methods! Teamwork among animals is more extensive and complex than we ever imagined! Animals also engage in bad behavior, like stealing from each other, committing murder, even going to war! In many ways the behavior of animals differs in degree, not in kind from human behavior.

And again like ourselves Chimpanzees are now known to make war one group against another! (Credit: Shutterstock)

Take intoxication for example, surely the drinking of alcoholic beverages is an activity that didn’t exist until we humans began fermenting grapes or grains or, let’s face it we’ll ferment any food with enough sugar in it. Well actually no, fermentation is a very natural process, a process that just happens to overripe fruits and grains as the yeast on their skins begins to convert sugar to alcohol.

The classical Greeks and Romans so loved wine that they created the god Bacchus to honour it. (Credit: Crystalinks)

And there have been numerous observations by naturalists of fruit eating animals in the wild eating overripe fruit and then acting inebriated. In fact many overripe fruits can have an alcohol content of 1-2% by volume and some, like the palm fruit in Panama, have been found to have an alcohol content as high as 10%. Also most fruit eating animals, like monkeys and bats are rather small so it takes less alcohol to get a spider monkey drunk than an adult human.

The Palm fruit of Central and South America is well known for undergoing the process of fermentation when it becomes over ripe, a naturally occurring form of alcohol. (Credit: Specialty Produce)

Still most naturalists assumed that drunkenness in animals was just an accident, not an actual behavior. That assumption is now being challenged by a new paper in the journal Trends in Ecology and Evolution.  While the paper accepts that drunkenness has its downside, it is certainly more difficult to avoid a predator’s attack if you are inebriated than if you are sober, there are still a lot of benefits to consuming alcoholic fruit.

Central American spider monkeys have now been observed to actually seek out over ripe fruit in order to get drunk! (Credit: Daily Mail)

For one thing it is packed with calories, the thing all living creatures need most, and the strong smell of alcohol may serve to lead the animals to the fruit. Alcohol can also have medicinal benefits, it kills many viruses and bacteria, that’s why we use alcohol wipes to disinfect. Finally the paper speculates that, as with we humans, the more social of fruit eating animals may actually use over ripe fruit, and its alcohol as a relaxant, an aid in socializing.

We humans use alcohol as a disinfectant, could some animals be doing the same thing? That would imply a considerable amount of intelligence on their part! (Credit: www.lazada.com.ph)

The paper concludes by stating that more research is needed before anything definite can be said. Alcohol occurs naturally in many ecosystems and if evolution has taught us anything it is that living creatures will find some way to make use of any resource.

Naturally occurring yeast on grapes just starts the process of fermentation. It doesn’t need any human effort to make alcohol. (Credit: Enobytes)

Another way that we humans thought that we were unique was in our ability to organize and coordinate really large scale hunting efforts. O’k there are wolf packs and lion prides but organizing really big kills, like the cattle drives of the old wild west or even just the harvesting of tuna or some other schooling fish, well that takes human ingenuity and cooperation.

Native American were known to drive large herds of Buffalo over cliffs as one method of hunting them. Surely only we humans are capable of such planning and organization. (Credit: Buffalo Bill Center of the West)

Or maybe not, in a recently observed episode off the coast of Norway researchers using the latest acoustic surveying techniques watched in awe as the largest predation event ever recorded took place. It began as a huge swarm of capelin; an anchovy sized fish that lives in cold artic waters, migrated southward to the Norwegian coast in order to lay their eggs. The oceanographers who witnessed the event estimated from the size of the swarm and its density that there were more than 20 million fish gathered in a school spread over tens of kilometers in area, that number is still only a small fraction of all the capelin in the Artic. Heading south the capelin ran straight into a large school of their most dangerous predator, cod.

During their mating season millions of Capelin, a small fish related to the anchovy, swim to the coast of Norway in order to breed. Such a huge amount of food naturally attracts many different types of predators. (Credit: Interesting Engineering)

Over the course of just a few hours of continuous feeding the cod consumed more than half of the capelin, over 10 million individual fish, making this the largest predation incident ever studied. It’s worth remembering however, that this slaughter was only completely observed because of the new technology and the resources necessary to cover the entire occurrence, so it probably won’t be long before even bigger battles are observed.

While the Capelin are eaten by cod the cod are then eaten by larger fish, or we humans! That’s the food chain. (Credit: Yale E360)

Just a few more of the ways that other the behavior of other creatures resembles actions that we thought were unique of our species.

Space News for January 2025. 

My last few posts about the latest news on the human exploration of space was all about the technical problems associated with Boeing’s Starliner capsule and the effects those issues had on the Space X Crew 9 mission as well as the International Space Station (ISS) in general. So, in this post I intend to ignore both the ISS and all missions to Low Earth Orbit (LOE). Instead, I’ll be talking about NASA’s plans for going back to the Moon and, unfortunately politics.

Putting American boots back on the Moon is the goal of NASA’s Artemis Program! (Credit: Max Polyakov)

As I’ve discussed in several of my past posts, see 3 December 2022 and 24 February 2024, NASA’s plan for returning astronauts to the Moon is called the Artemis Program and resembles the old Apollo Program in several ways. Like the old giant Saturn V rocket NASA will use the large Space Launch System (SLS) to launch the Artemis astronauts into space aboard a capsule called Orion that is similar to the old Apollo Command Module. The Orion capsule is also attached to a Service Module, again like Apollo. The actual landing on the Moon will be accomplished using a Landing Module, again like Apollo.

Space X is one of two companies that have been contracted to design and build the actual landing module for the Artemis program. They plan on using a modified version of their Starship lunch vehicle. (Credit: Spacenews)

The biggest difference between Artemis and Apollo is that for Artemis the Lander Module will not travel to the Moon with the Orion capsule and its Service Module but rather will go to the Moon by itself. NASA also hopes at some point to place a small space station into Lunar orbit from which the Astronauts will descend to the Lunar surface.

NASA’s plan for a space station in orbit around the Moon has been designated as the ‘Lunar Gateway’. (Credit: NASA)

NASA has already carried out one unmanned test mission of the SLS and Orion capsule back in December of 2022, a flight that was called the Artemis 1 mission, which was the first time that a man capable spacecraft had orbited the Moon since 1972. As the Orion capsule was returning to Earth however its heat shield underwent unexpected charring during re-entry and despite two years of testing NASA still does not fully understand the problem.

Because of that issue NASA has decided to once again delay the Artemis 2 mission, which will take human beings back to Lunar orbit for the first time since the days of Apollo. That mission was scheduled to launch in September of 2025 but according to a press release from the space agency the Artemis 2 mission will now take place no earlier than April of 2026. That delay will in turn further push back the Artemis 3 mission that is intended to finally return astronauts to the Moon’s surface until mid 2027 at the earliest.

To a certain degree the Artemis 2 mission will be a repeat of the Apollo 8 mission that orbited but did not land on the Moon. Nevertheless it will represent the first time that astronauts have gone back to the Moon in over 50 years. (Credit: Wikipedia)

There is one small plus to the delays in the Artemis 2 and 3 launch dates and that is it will give more time to Space X and Blue Origin to develop and test their Lunar landing modules. Both companies are contracted to build the vehicles that will take astronauts from Lunar orbit to the Moon’s surface and both are deep in the development stages for their respective landers.

Blue Origin is the other company contracted to build a lunar lander. This is their design. (Credit: Spacenews)

In fact NASA has just released contracts to both companies to develop unmanned cargo version of their landers. The development of cargo versions of the landers will allow NASA to place equipment on the Lunar surface before the astronauts arrive and to resupply the astronauts while there are on the Moon’s surface. One of the pieces of equipment that NASA is anxious to have on the Moon is a new pressurized rover vehicle being developed by the Japanese space agency JAXA and which is scheduled to be ready for the Artemis 7 mission in 2032. The long term establishment of a permanent base on the Moon will certainly require such cargo landers to deliver equipment and supplies.

Obviously making such long term plans and seeing them through to the end requires steady and constant funding and that requires a stable political situation. It’s with more than a bit of trepidation therefore that I tell you that President elect Trump has nominated Jared Isaacman to be the new Administrator of NASA, replacing the current NASA chief Bill Nelson.

With the incoming Trump administration NASA will have a new administrator replacing Bill Nelson (r) with Jared Isaacman (l). (Credit: NASA)

On the surface Isaacman seems like a good choice, the billionaire founder of Shift4 payments corporation has actually been into space twice, each time funding private space missions through Space X, which just happens to be owned by Isaacman’s good friend Elon Musk. See my posts of 17 March 2021 and 2 October 2021. Isaacman is an avid supporter of space exploration who is firmly committed to America’s having a leading place in that endeavour. It is quite possible that Isaacman may succeed in doing what’s necessary to get the Artemis program back on track and return America to the Moon.

In Jared Isaacman NASA will, for the first time have an administrator who has actually been in space! (Credit: NDTV)

It’s also quite possible that Isaacman and his buddy Musk will look at all of the delays and cost overruns in the Artemis program and decide to just cancel it all? Will he and Musk convince Trump to just let Space X take over the whole task of space exploration? Maybe skipping the Moon entirely to go to Mars, which is what Musk has always wanted!

Elon Musk has always wanted to go to Mars, not back to the Moon. Could he and his buddy Isaacman cancel the Artemis program entirely and set NASA on a new course? (Credit: Medium)

NASA has been jerked around like this countless times since Apollo. Reagan wanted to build a Space Station, but then George H.W. Bush decided to go to Mars. Clinton went back to Reagan’s plans and actually got a station built but then George W. Bush wanted to go back to the Moon again and it’s taken us 20 years to get at least some of the equipment ready.

In his State of the Union Address in 1984 Ronald Reagan directed NASA to build a space station within 10 years. It took a bit longer and we had to get the Russians to help! (Credit: NASA)

So, will all of the time and billions already spent on Artemis simply be tossed aside for some new vision of these two tech billionaires? And if the Trump administration does give NASA an entirely different goal, a goal that will certainly take years to complete, what if the next administration changes it once again? And all the while China, which doesn’t have to worry about new administrations changing course every four years, just keeps plugging away with its goal of landing Chinese taikonauts on the Moon by 2030!

Book Review: ‘The Brochs of Scotland’ by J. N. G. Ritchie. 

‘The Brochs of Scotland’ is a bit of an unusual book for me to review; the book is a type of publication that is known as a monograph, that is, a book or pamphlet on a single scholarly topic.  Monographs are usually small, ‘The Brochs of Scotland’ is only 56 pages total, and tend to be a bit technical. Because of their narrow focus of interest typically only a few thousand copies of a monograph are printed, often by a publishing house that specializes in such small, scholarly works. ‘The Brochs of Scotland’ is in fact printed by Shire Publishing, a division of Bloomsbury Publishing that is devoted to such books.

In the history of science a few monographs have gone on to become famous, the best example would probably be Galileo’s ‘The Starry Messenger’. Most monographs however remain virtually unknown to everyone but a specialist in the field or a devoted amateur.

As I was reading ‘The Brochs of Scotland’ I happened to notice that I have quite a few monographs, a few examples are ‘Stonehenge and Avebury’, ‘Seeing Stars’, and ‘A List of Devonian Fossils collected in Western New York with notes on their Stratigraphic Distribution’. I decided to review ‘The Brochs of Scotland’ not only because it would give me a opportunity to discuss these unusual Iron Age structures that are unique to Scotland but because it would also give me the chance to talk about monographs.

Mousa Broch is one of the best preserved Brochs giving a real impression of just how impressive the structures could be. (Credit: Wikipedia)

Brochs are a distinctive form of stone tower or fortress that were built by the hundreds between approximately the years 100 BCE and 100 CE. Brochs are unknown outside of modern Scotland and most are concentrated in the northern and western parts of the country, only a few Brochs can be found in the middle and southern parts of the country. The majority of Brochs are now ruins but a few are complete enough to show what impressive structures they were in their heyday.

Artist’s impression of what archaeologists think the interior of a Broch could have looked like. Obviously such large-scale structures required the efforts of many people to build and were probably the dwelling of the local chief or clan leader. (Credit: The Isle of Mull)

As I said Brochs are stone towers with a central open area round 10 meters in diameter where the inhabitants lived. This area was surrounded by a massive circular wall between 4 and 5 meters in thickness and as much as 10 meters in height. Those thick walls are perhaps the most striking feature of the Brochs because they are really a double wall with a space in between that averages around a meter wide inside them. Often the space between the walls was used as a room or storage area. At the same time stairways to the top of the Brochs were also built into the walls.

This image of the Dun Telve broch clearly shows the double wall construction technique. Storage areas and stairs to the upper floors were built into the walls of brochs. (Credit: MyHighlands.de)

Each Broch had only a single entrance from the outside to the central area, often with one of the rooms attached to the entrance, perhaps as a guard post? In any case the entrances were well protected, attachments for bolting heavy wooden doors can still be seen in the better preserved Brochs.

The area around a broch was also built up with houses and barns or other structures. The whole area was surrounded by a wall creating something of a small town, a well defended one! (Credit: Caithness Broch Project)

The whole design of the Brochs indicates that they were built for defense, the Iron Age equivalent of castles for local chiefs. However only a very few of the remaining Brochs show any sign of ever having been attacked, the author Ritchie suggested that they may have been built so well that it was a waste of time and effort to even consider attacking one.

The Castles of their day Brochs appear to have been so successful that archaeologists have found little evidence of any of them ever being attacked! (Credit: BBC)

If that was so then why did the 2nd century inhabitants of Scotland stop building them, why over the next few hundred years were the Brochs abandoned? In ‘The Brochs of Scotland’ the author considers both this question and the also unknown origins of the Broch style of architecture. The monograph also considers the questions of what it was like to live in Scotland at the time of the Brochs along with brief descriptions of some of the better known, better preserved Brochs along with some of the artifacts that have been found among them.

Some of the tools, jewelry and weapons made in Scotland during the age of the Brochs. There must have been something of an advanced civilization there at that time to have made both these artifacts and the Brochs as well! (Credit: Phys.org)

Now I don’t suppose that anyone out there is going to rush to buy a copy of  ‘The Brochs of Scotland’ unless you’re as interested in the archaeology of the British Isles as I am. It is actually available from Amazon if you are. Still, I do recommend ‘The Brochs of Scotland’; it is a wonderful overview of these ancient, formidable yet kinda weird habitations.

The people that the Greeks called Celts are still mostly a mystery. Although archaeologists have learned a great deal about them there is still a lot to be learned. (Credit: World History Encyclopedia)

And I also recommend monographs in general. They are wonderful little books, containing a great deal of information on very select subjects. So, if you have an interest in Hindu temples, or the birds of Chile, or the paintings of Rembrandt check to see if there are any available monographs on the subject. I’m sure someone has written one sometime or another!
