Talk:Cockcroft and Walton Experiment (view source)
Revision as of 06:15, January 24, 2013
, 06:15, January 24, 2013→This experiment by John Cockcroft and Ernest Walton is claimed by some physicists as demonstrating that E=mc2.
*''Instead, a hand-waving claim was made that an excess in kinetic energy of the resultant helium nuclei, which is greater than the energy of the original nuclei, must be attributable to a loss in mass.'' See (and answer!) [[# A few questions for Aschlafly regarding this experiment}]! There is no hand-waving, the loss of mass is observed!

*''But in fact the overall energy expended to attain this transmutation is greater than the energy produced by it. '' Yes, as most accelerated protons just go through the target!
*''But in fact the overall energy expended to attain this transmutation is greater than the energy produced by it. '' Yes, as most accelerated protons just go through the target - it isn't in the nature of physical experiments to be energy efficient!
That isn't a very promising start! --[[User:AugustO|AugustO]] 00:56, 24 January 2013 (EST)
