Our automatic ice maker is on the fritz, so we’ve temporarily reverted to making ice in conventional trays. But, imagine our delight at opening up the freezer and finding this!Several of our ice cubes apparently formed with long spikes on top. This is really *not* what you expect when you start out with liquid water in an ice cube tray. Snowcrystals.com has a fairly detailed explanation of how these things form, and it’s documented elsewhere as well. (Roughly speaking, supercooled water is pushed up through a hole, somewhat like magma forming a volcano.) It’s relatively easy to form these in your freezer if you start with distilled water, but occasionally– as in our case –they do occur with regular tap water.
“Phylm,” pronounced as “film,” is a portmanteau built out of the words “physics” and “film.” It’s also the name given to a new award, The Phylm Prize, aimed at spurring interest in physics and the educational use of new media. Translation: it’s a YouTube contest for physics geeks!
We’ve been invited to sit on the panel of judges for the contest, and so we’ll be looking forward to seeing the submissions. Videos up to two and a half minutes long featuring physics will be judged on clarity, accuracy, and creativity. This year’s winner will receive a check for $100 (US) to be dispersed in June 2007.
You can watch the video announcement at YouTube or (embedded) here:
We are guessing that many of you, our fine readers, already have an interest in physics and/or new media, so get started already! Let’s see your submissions! And don’t let the word “educational” intimidate you– educational propaganda is a highly appropriate diversion for evil mad scientists! (Besides, you could probably use the cash for your world domination scheme.)
Here’s some info from the rules on what kinds of things the clips can contain:
- A critique/analysis of the physics presented in a fictional work. For example,
could the bus in Speed have made “the jump,” or how strong would Spider-Man
have to be to throw a car that far?
- An analysis of physics as revealed by the examination of a real-world video clip.
For example, what forces does a gymnast experience during his routine?
- An explanation/presentation of some physics concept or theory. For example, what is the conservation of energy?
Submissions are due by 12:00 am (GMT) May 1, 2007. We’ll be waiting.
