While this is a good suggestion, this teacher should really be checking with their school about his options. I work at a private high school and when I was choosing a textbook (for an intro physics class) I wanted to forget about the textbook idea and use Feynman and a variety of problems (some my own some borrowed). The idea was shot down because the administration was worried about not being reaccredited. I ended up using an older version of a popular college level text book and Feynman.

While the specs are useless for vista, it works blazingly fast on Ubuntu with the Enlightenment Window Manager. The machine is now officially sold out of their online warehouses, and the product sales page at WalMart.com is full of glowing reviews from new and old linux users alike."

And you might think that it's as easy to take a picture of an atom with an STM as it is to take a shot with your digital camera. In fact, the imaging of individual atoms with a STM is awfully slow. But now, U.S. researchers had a very simple idea to accelerate this process. By adding a simple radio transmitter, they are able to make atomic-level microscopy at least 100 times faster. A typical STM has currently a sampling rate of about one kilohertz. This new radio-frequency scanning tunnelling microscopy can operate a thousand times faster. Very bright idea! But read more for additional details and a picture of a scanning tunneling microscope. I'm sure it's different from your expectations."

There they list the top science experiments — including the one from which the book gets its name — that were conducted by otherwise sane humans who tragically or otherwise ignored the effect of their research on the subjects themselves. Nowadays, most institutions have a review board for research on human subjects which would flag most proposals that could lead to harm for the subjects, but not so in the past.

Submission + - CNET tracks the history of the digital camera

Abby Donivosif writes: There's a really interesting article up on CNET about the history of the digital camera. It's incredible when you look through it how much things have changed in a relatively small amount of time and how evolved the technology is. Who would have thought 30 years ago that we would all be storing our pictures online and that our cameras would store hundreds of pictures, instead of just 36.
