In addition to his award-winning work in #physics, he is also remembered for a scale he devised to rank 20th-century physicists. It was an exponential scale, according to which 0 was the highest possible (indeed infinite) score, followed by 1 through 5, and because the scale was logarithmic, a “1” was considered 10 times more productive than a “2”, and a “2” ten times better than a “3”. #Newton was a “1”, as were Niels #Bohr and Paul #Dirac and several others. #Einstein was given the highest rank, a “0.5”, which made him about three times smarter, or at least more productive, than Newton and Bohr. #Landau initially ranked himself as a “2.5”, but later decided that he really deserved to be a “2” and moved himself up the scale.
