The Future Is Now: Terminator vs. Predator (Vision)

January 27th, 2008

Contact lenses are under development that will allow wearers to watch video and maps beamed directly into their eyes similar to the overlays from the Terminator movies.   Maybe I need to add those movies to my science-based sf films….naw.   I had similar technology in my first novel, and my pro-scitech stance led me to have lasik eye surgery about five years ago (still see 20/20, one of the best spent $1200 ever).

This is somewhat timely as my current topic in my Science and Science Fiction course this week is light and how it and its strangely wonderful properties are used in science fiction.   I used clips from Predator to illustrate “Predator vision” — seeing in the mid-infrared part of the spectrum at wavelengths at 7-14 microns where human beings glow brightly with thermal radiation.   We also looked at active camouflage used in the movie, which is also being developed.   Another topic we we will discuss is how light slows down through different substances, sometimes to ridiculously slow speeds, but nothing as extreme as in the classic Bob Shaw short story “The Light of Other Days.”   (It isn’t really feasible, but it is a really cool idea.)

There are a lot of different different classic science fiction stories depending on light.   Some that come to mind to me are “The Star” by Arthur C. Clarke, “The Lady Vanishes” by Charles Sheffield, “First Contact” by Murray Leinster, “Luminous” by Greg Egan, and I’m sure dozens more.   I’m always on the lookout for things for my class.   One resource that I use, but could use updating, is Andy Fraknoi’s list of Science Fiction Stories with Good Astronomy and Physics.   I’ve thought about making my own such list, but it seems a little daunting to do a comprehensive job.
