Morphing Metals

aarondubrow writes "Imagine a metal that 'remembers' its original, cold-forged shape, and can return to that shape when exposed to heat or a magnetic pulse. Like magic out of a Harry Potter novel, such a metal could contract on command, or swing back and forth like a pendulum. Believe it or not, such metals already exist. First discovered in 1931, they belong to a class of materials called 'shape memory alloys (SMA),' whose unique atomic make-up allows them to return to their initial form, or alternate between forms through a phase change."

  1. Imagine an OS by kainosnous · · Score: 0, Offtopic

    Imagine an OS that doesn't need virus protection, doesn't crash, and is completely customisable. Imagine a browser that doesn't beg for viruses and follows a consistent set of standards between release rather than arbitrarily making new rules each time. Imagine software that is free and useful that doesn't come from some shady site that you've never heard of. Believe it or not, such software already exists. It's called FOSS, and an entire toolchain has been built with it allowing all sorts of new and powerful applications.
