I forgot to say that Sidis even surpassed Norbert Wiener, himself an ex-child prodigy, whom he knows at Harvard because the created together a club of geniuses with only 3 members...( the other being the music composer Roger Sessions if my memory is good)
Norbert Wiener created Cybernetics by himself or old A.I , and make deep discoveries in mathematics and in physics like the late Janos von Neumann...But unlike Neumann the sympathetic Wiener refuse to speak to anyone who worked for the military... Think about that....A commoon point with Sidis who declare at 11 years old that he will take the SACRED VOUCH to never invented ANY technology because humanity is too war-like and dont understand society ( save some Indians tribes Sidis considered more advanced)
Believe it or not by the precocity of talents and the mastering of fields at young age , Sidis Exceed these two, Wiener and Neumann who worked among other thing the FIRST architecture of computers and who were the most gifted scientist in the world ....
A last point how do we know Sidis I.Q. ?
He lived before the second world war at a times where all government job necessitate testing routine I.Q. formulary , and at each new job he was tested and sometimes recognized because he was over any testable scale in I. Q. He quitted often many jobs because he hate to be named a "genius" after his own mother exploitation and his father bragging and stricted education...His I.Q. is only guessed by putting him out of the scale at least with 250....And probably 300 which is two times the minimal number usually associated with genius : 145...
He worked sometimes with 2 mechanical additive computer , one for each hand, and like it because he said i can think at the same time... 😊
His father spoke more than 20 languages, i think 24, wrote 17 books and was considered one of the greatest psychiatrist and psychologist in America with his friend William James who gives his name to the Sidis baby... He taught medecine to his uneducated future wife and euclidean geometry before marrying her , she was herself a genius they married and decided to train their baby... The rest is history...
Do you know why i quit reading S-F novel long ago?
Reality exceed fiction in miracles and mysteries....Reality dont ask to be believed first and last ...
