I would like to see your friends IQ test. Langan is an idiot (wants to genocide/eugenics people, that, in his OPINION shouldnt pass their genes on) Davinci and Newton are the greatest contributors to mankind on that list. Fischer was genius sad story really, i really feel for him he is dead now obv (has a good documentary 'Bobby Fischer against the world'). Savant believes in 'evolution' so.... Tesla should be on that list, he was around same era as Einstein, worked harder and contributed more to mankind...
