Earlier this evening I was feeling a bit guilty and catching up with a bit of reading at arXiv. For those of you who aren’t familiar with arXiv, wikipedia comes to the rescue:
arXiv is an archive for electronic preprints of scientific papers in the fields of physics, mathematics, computer science and quantitative biology which can be accessed via the Internet. In many fields of mathematics and physics, almost all scientific papers are placed on the arXiv. As of June 2007, arXiv.org contains over 423,000 e-prints, with roughly four thousand new e-prints added every month.
arXiv is broken down by subject area, and I usually confine my reading to astro-ph, where pretty much every single scientific paper in astronomy is released, for free, to the community. Today, for some reason I took a look through the category list and found physics.pop-ph, the repository of articles about popular physics. One title in particular stood out, and I couldn’t resist having a read:
Hollywood Blockbusters: Unlimited Fun but Limited Science Literacy
I’m really not sure what to make of the article, it is all very po faced and hyper-serious, but I just can’t help laughing at the indepth analysis given to some films. For example, there is a scene in The Core where the heroes go deep underground and get out of their vehicle.
We could discuss many questionable issues with this scene: (a) Could a cave exist at such depths? (b) Could the crew afford to open and close the door of the vehicle in such a depth? This would mean the loss of breathable air from the vehicle and changes in the air pressure and temperature of the vehicle. (c) Could the flexible suits that the crew is wearing really protect them at that depth? Many more questions could be added in this list. The reader can reflect on these issues on his own. We will only discuss the sinking of a human body in lava
I can’t even tell if the authors are being serious, or wrote this whole thing for a laugh in the pub. Don’t even get them started on why time would probably not go backwards when superman flew around the earth, or why in X-Men: The Last Stand the bit where Magneto moves the golden gate bridge is not feasable (unless Magneto is powered, like the sun, by fusion).
The relocation of the bridge gave to the director an opportunity for great special effects. However, even with the acceptance of Magneto’s special powers, it is an unrealistic scene given the physical laws in our universe
The whole paper is absolutely brilliant and I urge everybody to read it.
I really like the idea of doing some movie reviews focused entirely on movie physics, think Angry Nintendo Nerd but with graphs and equations and foul language.
Finally, as a single word of advice. If you’re ever in a situation where either of the authors of this paper ask you to watch a movie with them you should respectfully decline.
