So where do geniuses come from? Unfortunately, the answer is unknown to anyone.
But some interesting assumptions can still be found in the book "Surely You're Joking, Mr. Feynman!".

Many will say that it all depends on genes. Yes, undoubtedly, genes are the main clue of any personality. It cannot be done without them. But there are other equally important circumstances.

Only a free world gives birth to free individuals, ready to take as much as possible from life. And give back as much, if not more. Almost all winners of the Nobel Prize and other prestigious world awards belong to the free world. Oppressed continents, which were the majority not long ago, do not produce geniuses.

And it is the geniuses that are the progress of the world. Humanity needs them to improve the lives of every individual. Now this quality multiplies not in centuries, but in decades.

But let's get back toRichard Feynman.
The book is a vivid example of how a person enjoys life, in a good, sublime sense.
