Vintage 6x8 B&W glossy photograph signed by George Paget Thomson in fountain pen ink. Scattered creasing, otherwise, in good condition.(1892-1975) Sir George Paget Thomson was a British physicist and Nobel laureate in physics recognized for his discovery of the wave properties of the electron by electron diffraction. After briefly serving in the First World War Thomson became a Fellow at Cambridge and then moved to the University of Aberdeen. George Thomson was jointly awarded the Nobel Prize for Physics in 1937 for his work in Aberdeen in discovering the wave-like properties of the electron. The prize was shared with the American physicist Clinton Davisson who had made the same discovery independently. Whereas his father had seen the electron as a particle (and won his Nobel Prize in the process), Thomson demonstrated that the electron could be diffracted like a wave. By scattering electrons through thin metallic films (3.10−6 cms) with known crystal structures, such as aluminum, gold, and platinum, Thomson found the dimensions of the observed diffraction patterns. In each case, his observed diffractions were within 5 percent of the predicted values given by de Broglie's wave theory. This discovery provided further evidence for the principle of wave–particle duality which had first been posited by Louis-Victor de Broglie in the 1920s as what is often dubbed the de Broglie hypothesis.This lot came from the Jim Wiggins collection we purchased in July 2022. Jim Wiggins accumulated the most unique and valuable autograph collection over a period of 70-plus years. He obtained his collection either in person or by writing to persons of fame and notoriety. Comes with a full Letter of Authenticity from Todd Mueller Authentics.
