Grey Matter Quotes (1 quote)

Via George Pσlya, present at an early lecture on Special Relativity by Einstein, who at the time preferred to show his own old formulation, not yet embracing Minkowskis geometrical reformulation. Quote given as Pσlyas recollection in J.E. Littlewood, A Mathematicians Miscellany, (1953). Also in the expanded edition, Bιla Bollobαs (ed.), 'Odds and Ends',
Littlewoods Miscellany (1986), 152.
