(PhysOrg.com) -- The problem exists on both a large and a small scale, and it even bothered the ancient Egyptians. However, although physicists have long had a good understanding of friction in things like stone blocks being pulled by workers into the shape of a pyramid, they have only now been able to explain friction in microscopic dimensions in any degree of detail.

Thanks to a new online toolkit developed at MIT and the Lawrence Berkeley National Laboratory, any researcher who needs to find a material with specific properties — whether it’s to build a better mousetrap or a better battery — will now be able to do so far more easily than ever before.

Einstein’s explanation of special relativity, delivered in his 1905 paper On the Electrodynamics of Moving Bodies focuses on demolishing the idea of ‘absolute rest’, exemplified by the theoretical luminiferous aether. He achieved this very successfully, but many hearing that argument today are left puzzled as to why everything seems to depend upon the speed of light in a vacuum.
