All atoms move constantly. When they are hot, they move faster. Usually the atoms in an object hold together and give the object its shape. But if the object grows hot, its atoms move so fast that they break the force that usually holds them together. They move...
aNanotechnology is about building things atoms by atom, molecule by molecule. The trick is to be able to manipulate atoms individually, and place them where you wish on a structure. Nature uses molecular machines to create life. If you want to see a nanotechnology machine, just look in the...
