The Ultimate Field Guide to Subatomic Particles
This is, for the most part, an accurate article, except for a few statements. "Exactly what makes a fermion a fermion is a bit complicated, but suffice it to say that fermions are all the particles that deal with matter. So what about the last group of elementary particles, the ones that don't deal with matter?

Gas Molecule Motion, Heat, Temperature
At a low temperature a gas molecule travels, on the average, at a slower speed than than it would at a high temperature. So, at a low temperature the molecules have, on the average, less than they do at a high temperature. Lower speeds, lower kinetic energies. If we imagine a gas molecule as a green circle: Temperature, when measured in Kelvin degrees, is a number that is to the average kinetic energy of the molecules in a substance. So, when the molecules of a substance have a small average kinetic energy, then the temperature of the substance is low.
Physics Flash Animations
We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. Also included is the minimum version of the Flash player that is required; the player is available free from The categories are:
7 Man-Made Substances that Laugh in the Face of Physics
Odds are pretty good that some of you are reading this on an LCD screen while the rest of us are trying to make it out on the 13-inch monochrome monitor that came with our garage sale Commodore 64. But even with the LCD, some laptops still weigh over 10-pounds. And while that doesn't seem like much, the level of muscle atrophy experienced by the average Warcraft addict makes that weight a thousand times heavier.
