... The approach of von Neumann and Connes to the use of non-commutative algebra in physics is naive, the situation is much more complicated.

In the Middle Age, in Germany, if you wanted to learn addition and multiplication, you could go to any university. But if you wanted to learn division, you could only do it in one place, Heidelberg. This makes sense, since in my theory with Vladimir Retakh and Robert Wilson, addition and multiplications are cheap, but division is expensive.

My life may be encapsulated by one of Graham Greene's "entertainments" titles: 'Loser Takes All'. Since I was thrown out of highschool for political reasons, I was free to study on my own and develop my own ways of thinking.

The older I get, the more I believe that at the bottom of most deep mathematical problems there is a combinatorial problem.

If you understand something, you understand that it is obvious.

One of the reasons we don't do as well as we should is that we are all over-taught.

People (or students) do not have shortcomings, only uniquenesses. The goal of a good teacher is to turn these uniquenesses into advantages.
