“ Physicists in Italy are developing a new device for assessing the condition of some of the country's most valuable fresco paintings. The tool can reveal information about the condition of a wall painting without ever touching its surface, making the device a potentially valuable aid to restoration and preservation efforts.”

Singing dunes
“ Ever since Marco Polo, explorers have told stories about strange sounds they have heard in the desert. It is known that these sounds are produced by sand dunes when they avalanche, but the exact mechanism behind the phenomenon has remained a mystery.”

Albert Einstein and meandering rivers
“ I begin with a little experiment which anybody can easily repeat. Imagine a flat-bottomed cup full of tea. At the bottom there are some tea leaves, which stay there because they are rather heavier than the liquid they have replaced. If the liquid is made to rotate by a spoon, the leaves will soon collect in the center of the bottom of the cup. The explanation of this phenomenon is as follows: the rotation of the liquid causes a centrifugal force to act on it.”

Using Flash animations to illustrate physics is something I tried a while ago. I find it most interesting but, unfortunately, my knowledge of physics is limited.
