Introducing Magnet-Responsive Memory Foam

Roland Piquepaille writes "The U.S. National Science Foundation (NSF) has recently reported that two research teams have developed a new porous foam of an alloy that changes shape when exposed to a magnetic field. The NSF states that this new material is able to remember its original shape after it's been deformed by a physical or magnetic force. This polycrystalline nickel-manganese-gallium alloy is potentially cheaper and lighter than other materials currently used in devices ranging from sonar to precision valves. It also could be used to design biomedical pumps without moving parts and even for space applications and automobiles."

Thanks for expanding my point

It wasn't a jibe at Republicans. It was a jibe at a world in which the most advanced technological power can produce people who don't seem to have the least idea of the basis on which that power rests, and don't seem to care. It may be that if GWB had had a proper scientific education he might have tended to, say, believe the weapons inspectors and his own military rather than the spin merchants, though we can't be sure. It might be that he would, say, read Scientific American or National Geographic, and this would inspire him to leave a legacy of a serious attempt to solve world problems through the encouragement of science and technology

I'd be almost equally happy if future politicians got a really good grounding in history, instead of being told that it is irrelevant.
