The first verification of this principle came from the first human-controlled nuclear disintegration experiment, in which a lithium atom was split into two alpha particles, which was performed by Cockcroft and Walton.

When converting between "rest" and "total" forms of the quantities in this principle, an additional factor of momentum times speed of light, all squared, appears. Due to this principle, particle physicists often use natural units to express particle (*) mass in terms of giga-electronvolts. This principle was first stated in the 1905 Annus Mirabilis paper that proposed special relativity. For 10 points, identify this principle proposed by Einstein and demonstrated by the famous equation E equals m c squared.
