Feynman and his beautiful mind was just an amazement of brilliance.
My Understanding of this marvelous insight.
you don’t have to grasp the maths behind something to see what people are calling to be brilliant. (of-course maths can be wrong and that’s where many can focus)
Check this out; D = √2(M+1) – 1
Feynman and Ralph calculated this, they used to go to a restaurant (in Pasadena?) together. They found that if you are to go to a restaurant lets say 10 times (in a month lets say) then how many times you can take an un-rated meal before you try only the best-rated of that meal to be able to claim after the 10 meals “I have always had the meals in a way I have the best-average rating of meals”
( if such rating are available, but you don’t know the rating, and there is only a maximum number of meals available in the eatery, then let that number be N, N numbers of meals you can ever try, each, one time)
