Movie Review: Arrival

I have a big problem with this Movie! The alien visitors are not only smart enough to span interstellar space and come to Earth they are smart enough to have a deeper understanding of time than we do. And when they arrive on Earth they know that we are a divided species, they seem to know something of our physiology and technology. Yet somehow they haven’t managed to learn English or any other Earth language, nor do they manage to do so by the end of the movie. Seriously, at the film’s climax Amy Adams is trying to get the big message across to them using their language!

I had the same problem with Close Encounters of the Third Kind back in 1977, I know that’s almost heresy but it’s true. In CE3K the aliens have been watching us since at least Dec1945 when they abducted Navy flight 19 but in the next 32 years they haven’t learned English! I’m sorry but that really ruined CE3K for me and it pretty much ruins Arrival.

I remember the old 1950 Film “The Day the Earth Stood Still” where at the beginning of the movie the Alien Klaatu walks out of his flying saucer speaking perfect English. He explains this by announcing that “they” have been listening in on our radio and TV broadcasts. Which is probably how any aliens would learn about our existence in the first place.

Arrival’s best part is in fact where Amy Adams learns the aliens written language where every word is based on a circle (see example below). They state in the film that this makes every word a palindrome, a word that is spelled the same backwards and forwards, but if you look at the example that’s not true, the alien symbol is different depending on whether you go around the circle clockwise or counter-clockwise.

As to the Aliens of Arrival themselves, they aren’t very interesting. They look pretty much like octopuses that have lost one tentacle and we don’t get to see a great deal of their technology. The film is really more about how we humans react to the arrival of aliens than the aliens themselves. In that case however “Arrival” spends too much time with Amy Adams and Jeremy Renner and we only get snippets of news reports on how humanity as a whole is reacting.

Serious Science Fiction movies are rare and need to be supported but I just can’t give it my wholehearted approval. It’s not bad, it’s just not very alien. The scriptwriters needed to spend more time on the aliens and not just their language. Well, that’s my opinion, what’s yours?

 

Better Thanksgiving through Chemistry

Some holidays are religious, some are patriotic but let’s be honest, Thanksgiving is all about the food. So tomorrow, as we wait impatiently for ma, or grandma, to perform that wonderful miracle in the kitchen maybe we should all take a moment to think about chemistry, that’s right chemistry.

Cooking is really just practical organic chemistry after all. Consider the changes your turkey will go through as the heat of your oven makes it so delicious. The muscle proteins will coagulate making them easier to digest, the carbohydrates in the skin will caramelize making it nice and crispy while the lipids will liquefy making everything wonderfully moist.

Heat is also important in preparing our vegetables, breaking down the tough cellulose cell walls. If you boil your potatoes don’t forget to salt the water, and not just for taste. Salt also raises the boiling temperature of water and is simply a good catalyst speeding up many chemical reaction.

Besides heating there are other important cooking techniques as well. Consider making a nice vinaigrette for your salad. Now we all know that oil and water don’t mix but if you employ mechanical agitation, shake them or stir with a whisk, you can produce thousands of little oil bubbles suspended in the vinegar. This is called an emulsion and here’s a little secret, add a teaspoon of mustard before you shake. The proteins in the mustard dissolve in the vinegar but can hook onto one of those oil drops helping to keep the emulsion from separating. The mustard also adds a lot of flavor.

Perhaps the most complex chemistry performed in the kitchen involves yeast. Yeast are living cells of a fungal organism and their metabolism is as complex as any creatures but we humans use then basically for two purposes. When added to a mixture of carbohydrates and lipids, flour and butter, the yeast will produce carbon dioxide bubbles making the bread dough rise. The other use is to produce alcohol from simple sugars giving us the nice glass of Riesling I plan on having with my turkey.

Yes, a delicious meal is really just better living through chemistry. Have a Happy Thanksgiving.

Space and Dinosaurs in one article, who could ask for anything more!

Recently there have been a few stories about a scientific project to learn more about the asteroid that led to the extinction of the dinosaurs. Researchers Joanna V. Morgan of the Imperial College of London and Sean P. S. Gulick of the University of Texas at Austin have been drilling thirty kilometers off the Yucatán peninsula in the Gulf of Mexico looking for the inner “peak” ring inside the larger crater rim caused by the asteroid  that struck Earth 66 million years ago. To see the original article in Science click the link below.

http://www.sciencemag.org/news/2016/11/update-drilling-dinosaur-killing-impact-crater-explains-buried-circular-hills

These inner rings of craters have been often seen on our Moon and other Planets and moons in the solar system but where unknown here on Earth before now. With the samples of granite and other materials retrieved by the scientists we are now able to study this type of crater formation up close.

The present model for the formation of these double ringed craters is shown in the figure below.

Data and samples gained from the present drilling project will help to either confirm or reject the current model.

Like the dinosaurs, we are still threatened by another such disastrous collision from outer space. Unlike them however we are beginning to develop the necessary technology to recognize the threat before it strikes and someday soon to prevent the disaster from occurring.

Quick update: Just this morning a new article in Live Science has reported that the scientists drilling into the Yucatan crater believe that the asteroid may have actually punctured the Earth’s crust. If that is true some of the samples the team are finding may be material from the Earth’s mantel, a region of our planet less well explored than our Moon. Use the link below to read the article.

National Geographic Channel Gives Us A Night Of MARS

Last Night the National Geographic Channel debuted the first episode of it’s new six part miniseries “Mars” from Producers Ron Howard and Brian Grazer. Formatted as a dramatization of the first voyage to Mars the program adds in comments from some of the scientists and engineers who are working to make that first voyage actually happen.

In the first episode we were introduced to the international team of six men and women who will take the spaceship “Daedalus” to Mars. Last night’s episode concentrated in the difficulties and dangers of the actual landing on the red planet. Without giving away to much, a life threatening malfunction occurs, the mission commander is injured while fixing the problem enabling the Daedalus to land safely.

It appears to me that the plot for each episode will resemble last night’s in examining one aspect of the voyage to Mars, adding in an emergency and letting the crew survive by their technical skill and courage. My biggest criticism of last night’s episode would be the sound, with the crew’s helmets on and all of the background noise I never did get to hear what the malfunction actually was.

The interspersed comments from the scientists included Elon Musk the CEO of Space X corporation, Neil deGrasse Tyson the Director of the Hayden Planetarium and host of Star Talk, Andy Weir the author of “The Martian” along with my favorite astronaut (I met him once) Jim Lovell and a host of other scientists. In general the commentators succeeded in informing rather than interfering but towards the end I almost got the feeling I was watching a commercial for Space X.

We’ll see how future episodes go, I’ll certainly be watching. National Geographic has announced that they plan on producing more series like Mars and less of the the Tuna Fishing, Surviving in the wild with nothing but a camera crew to help type of reality show and I for one appreciate the change.

After the premier of Mars came the weekly installment of Star Talk with the aforementioned Neil deGrasse Tyson. Doctor Tyson’s guests were the aforementioned Andy Weil along with NASA Engineer Adam Steltzner the team leader on the Mars Curiosity Rover’s sky crane landing system and Jim Green, NASA’s lead planetary scientist. As you might guess the discussions were all about Mars without making an explicit tie in to the miniseries.

Television was once described by Newton N. Minow as a “Vast Wasteland”. Well last night the wasteland of Mars gave us some of the best TV I’ve seen in quiet a long while.

Movie Review: Doctor Strange

The Marvel Universe has released its latest comic to movie superhero in Doctor Stephen Strange. Marvel has certainly developed a winning structure for action movies and while Doctor Strange may not be a high point in the Marvel Universe it was still an entertaining installment.

The biggest problem is the first third of the movie, where noted neurosurgeon Doctor Strange has a car accident, injuring his lifesaving hands. Abandoning western medicine he seeks a cure in eastern mysticism, becoming a super magician, and learning the truth about himself in the process

What we get is simply trite. We’ve seen all this before and the comparisons to other movies are so easy to make. I’ll use Star Wars as an example. Tilda Swinton is the Yoda character, Chiwetel Ejiotor and Benedict Wong share the Obi Wan duties while Benedict Cumberbatch is of course Luke Skywalker. There are scenes of Luke…er, Stephen in training along with the required ‘wise’ sayings stressing how no sense makes sense.

As you can tell from the cast the acting is excellent, only Mads Mikkelsen in the Darth Vader role is unconvincing, and to be honest he has very little to work with aside from just being the baddie. The special effects are also high quality. The bending of reality does manage to generate a genuine feeling of vertigo.

The film picks up a bit of steam when Strange’s artifact finds him. A mage doesn’t find his artifact, it finds him. Again, that’s a little trite. I won’t give away the ending except to say it was the best part of the film with Strange being clever in defeating his foe rather than just another fight scene.

I’m not saying Doctor Strange was a bad film, it just needed a good bit more care in the early part of the script. If you’re looking for something thought provoking, or even just clever plot twists you’ll be disappointed. But if you’re just looking for an enjoyable night’s entertainment Doctor Strange will do the trick.

Oh, and one last thing. Since Doctor Strange will be an integral part of the Marvel Universe, ya kinda have to see this this movie in order to keep up with what’s going on in the rest of MU. Clever boys there at Marvel aren’t they.

P.S. Monday night, 14Nov16, the National Geographic channel will debut the first installment of its six part miniseries ‘Mars’. You can bet I’ll be watching, and posting!

Book Review: “On to the Asteroid” by Travis S. Taylor and Les Johnson

Just finished reading the new (Aug16) novel “On to the Asteroid” by Travis S. Taylor and Les Johnson, a hard science look at space travel about twenty years from now. If you’re like me and are anxious for humanity to return to the Moon, get going on exploring Mars and begin living, working and profiting from space I can recommend “On to the Asteroid” without reservation.

The basic plot, a runaway asteroid is going to strike the Earth is actually the weakest element of the entire book. We’ve seen all this before whether in novels, Arthur C. Clarke’s “The Hammer of God” or movies “Meteor”, “Armageddon” and Deep Impact” and I’m sure I’ve missed a few. That said “On to the Asteroid” is a thrill ride in a high-tech spaceship with plenty of plot twists, a homicidal maniac along with harrowing escapes from certain death.

The Authors, Travis S. Taylor and Les Johnson certainly know their science and technology. Taylor is an aerospace engineer, author and appears in National Geographic Channels “Rocket City Rednecks” while Les Johnson is a physicist who works for NASA at their Advanced Concepts Office so you know the science is done with three digit accuracy. Like Andy Weir’s “The Martian” the science of “On to the Asteroid” is the solid foundation of an adventure unlike anything anyone has yet experienced.

“On to the Asteroid” is a quick read, it took me two days to finish. It reminds me somewhat of the Dan Brown novels that have something happen every page which keeps you turning to the next page. I’m not going to spoil the ending or anything but “On to the Asteroid” is a roller coaster ride that will keep you in suspense till the very end.

“On to the Asteroid” isn’t either philosophical nor psychological. It isn’t great literature, but it is what science fiction has always done best, it takes you to other worlds!

These are a few of My Favourite Things

I assume anyone who visits this blog, or at least anyone who comes back, has an interest in science, space and astronomy. With that in mind I thought I’d take a moment to tell you all about some of the web sites I like to visit, these are a few of my favourite things.

I guess the best place to start would be NASA’s main page. Now this page is pretty general, intended for students and the general public but it does allow you to access to information on every mission NASA has ever undertaken. Seriously, there’s a lot of good stuff to be found here.

http://www.nasa.gov

Another NASA site, which actually isn’t easy to get to from their main site, is “How to spot the Station” which allows you to get detailed sighting information to find the International Space Station as it flies over your head. I’ve seen that station now over thirty times and it’s always pretty cool

http://spotthestation.nasa.gov

And if you like NASA you’ll love the Jet Propulsion Labouratory (JPL) in California. Their main page is also general interest but again, if you look around there’s a lot to see.

http://www.jpl.nasa.gov

JPL also has a really cool site that’s hard to get to from their main page. This is the small body database. Orbital and physical parameters for thousands (it’s growing all the time) of small asteroids and other objects in our solar system. It takes a little bit of figuring out but I really love the orbital diagrams, especially for Near Earth Objects (NEOs). Caution, the orbital applet is JAVA enabled so you need JAVA on your computer.

http://ssd.jpl.nasa.gov/sbdb.cgi

There are now several commercial sites that are also worth checking out on occasion. The best known is Space.com which is a news site dedicated to the latest happenings in space.

http://www.space.com

A new one, as far as I know, is Spaceflight insider. This site also has space news but it also has a launch calendar of upcoming launches from around the world.

http://www.spaceflightinsider.com

One last cool space site is SpaceWeather.com. Yes there is a web site dedicated to giving you the latest weather report from our solar system. A couple of interesting things to see here are the latest sun spot report, the solar wind and cosmic ray intensities and near Earth asteroid approaches during the next month.

http://www.spaceweather.com

Now let’s change course a little bit and look at some astronomy sites. I guess a nice segue would be the main web site for the Hubble space telescope. You can spend days just going through the beautiful images.

http://hubblesite.org

One of my favourite sites is the SEDs Messier data. Charles Messier was a French astronomer about the time of our revolution who was studying comets. Well he made up a list of fuzzy objects that weren’t comets. The objects on that list turned out to be galaxies and nebula and star clusters and supernova remnants. The SEDs site has tons of beautiful images of these objects.

http://messier.seds.org

A daily astronomical note of interest can be found at Stardate.org by  the McDonald Observatory in Texas. They often have information on things to see in the sky tonight.

http://stardate.org

Another observatory with a cool web site is Keck in Hawaii. Again plenty of beautiful images.

http://www.keckobservatory.org

A great commercial site is Sky and Telescope magazine. The best part of their site, as far as I’m concerned, is the interactive sky chart which can show you what the sky will look like anywhere in the world not just for tonight but for any night for the next hundred years. Oh, and the last hundred years as well. Lemme tell ya, I’ve planned many nights of stargazing using that site. This is also a great place to look for telescope and accessories to buy.

http://www.skyandtelescope.com

This getting to be a bit of a long post so I think I’ll save Physics and Paleontology and Archeology for a later date. I have one more site for today and it’s possibly the most interesting. Back in the 1960s Jodrell Bank Radio observatory in Manchester England discovered the astronomical objects know a Pulsars. Well Jodrell Bank has a web page where you can hear, that’s right hear the sound of collapsed stars only a couple of kilometers across that are spinning so fast that they generate a magnetic field so huge it shoots out a radio beam like a searchlight and every time that beam passes Earth Jodrell Bank hears a click. So go to this site and listen to the sound of a dead star.

http://www.jodrellbank.manchester.ac.uk/research/pulsar/education/sounds

You may have noticed I haven’t even mentioned Science Fiction. Don’t worry, I get ’round to it.
