An experiment by Cockcroft and Walton is heralded by most physicists as demonstrating that E=mc2[1] Conducted in April 1932 in Cambridge England, physicists John Cockcroft and Ernest Walton successfully split lithium atom nuclei by colliding them with artificially accelerated protons. This experiment is general hailed as being the first transmutation of an element using artificially accelerated particles, for which they were honored with the Nobel Prize in 1951[2]. Since the experiment showed that mass could be converted directly into energy through nuclear transmutation it is often heralded as being verification of Einstein's famous E=mc2 formula[3][4]. Critics maintain that such verification is impossible due to the utter lack of any logical justification for that science fiction formula.
