  1. options on Chemistry Tasks For the Computer Lab? · · Score: 1

    You could try to introduce basic computational chemistry through ChemOffice or PCmodel. Have them find the lowest energy conformation for a particular cyclic structure. Have them explain why adding a particular group at a particular location increases the conformational energy. Or just integrate this into their lab reports by having them create these 3d/kekuli structures in ChemOffice and paste them into their reports. Searching through the literature for chemical information is a very important skill to develop as 6 hours in the library can potentially save 6 months in the lab. But as a high school, I doubt you have access to Merck Index online or the other expensive chemical databases. I think an ability to search MSDS databases would be appropriate for high school students. These are can be found for free online and you build good safety habits by making your students comfortable searching for safety information (ignition temp, vapor pressure, hazards, etc...) for chemicals they will use. Most university programs teach these skills anyway but they will have a head up on the assignment. gl hf dd.

  2. Metal Gear Solid on How PALS Help Secure Nuclear Weapons · · Score: 1

    MGS for PSX taught me all I need to know about the PALS authentication system and international terrorism. Campbell : I'm afraid so. At the very least, they've got their hands on a real nuclear warhead. Snake : Isn't there some kind of safety device to prevent this kind of terrorism? Campbell : Yes. Every missile and warhead in our arsenal is equipped with a PAL, which uses a discreet detonation code. Snake : PAL? Campbell : Permissive Action Link. A safety control system built into all nuclear weapons systems. But even so, we can't rest easy. Snake : Why not? Campbell : Because the DARPA Chief knows the detonation code. Snake : But even if they have a nuclear warhead, it must've been removed from its missile. All the missiles on these disposal sites are supposed to be dismantled. It's not that easy to get your hands on an ICBM (intercontinental ballistic missle). Campbell : That used to be true, but since the end of the Cold War you can get anything if you have enough money and the right connections.

  6. Re:About Flying on The Physics of Superman · · Score: 2, Interesting

    Ampathee is exactly correct. The physicist in the show suggested that while Lois would travel at her terminal velocity downward, Superman would be flying at an extreme velocity in the opposite direction. He guessed that Superman would be flying at ~100x faster than Lois would be falling down, or 120,000 mph in order to grab her (since he had to run to a spot, change clothes into Superman, and fly to grab her all the while Lois is falling at 9.8 m/s^2). It would be awesome to see Superman accidentally slice Lois in half in an attempt to save her, they must save that shot for the Directors Cut.
