The popular book The Martian by Andy Weir will be released in movie form on October 2. The Martian is about an astronaut, Mark Watney, stranded alone on Mars. The crew of Ares 3, the third manned mission to Mars, thought he had been killed during an evacuation. When the crew left, they took the only planned means of escape and communication with them. The next manned mission to Mars isn't for four years, so Watney has to face the fact that he must either figure out how to survive for up to four years on Mars or die. The book does a wonderful job of supplying technical details of the conditions and supplies available, as well as of the problems that arise as a result of using things in ways for which they were not designed. The details are great for allowing us to explore the travels of the main character with the Wolfram Language. It's at this point I should probably post a warning: SPOILER ALERT! From here on I will be exploring aspects of the story and so will be giving away plot points. If you don't like those kinds of details, stop here and go read the book... and then come back and read this blog.
