“The scientific theorist is not to be envied. For Nature, or more precisely experiment, is an inexorable and not very friendly judge of his work. It never says "Yes" to a theory. In the most favorable cases it says "Maybe", and in the great majority of cases simply "No". If an experiment agrees with a theory it means for the latter "Maybe", and if it does not agree it means "No". Probably every theory will someday experience its "No" - most theories, soon after conception.”
― Albert Einstein

“In the empirical sciences, which alone can furnish us with information about the world we live in, proofs do not occur, if we mean by 'proof' an argument which establishes once and for ever the truth of a theory.”
― Karl Popper

“In Mathematics, 10x1 and 1x10 are exactly the same.

In real life, they are almost opposite.

You can easily fool 10 different people for 1 time each. But to fool 1 person for 10 times is very difficult.”

“Robert Shiller, a finance professor at Yale University, says Graham inspired his valuation approach: Shiller compares the current price of the Standard & Poor’s 500-stock index against average corporate profits over the past 10 years (after inflation). By scanning the historical record, Shiller has shown that when his ratio goes well above 20, the market usually delivers poor returns afterward; when it drops well below 10, stocks typically produce handsome gains down the road.”
