Here in Oxford’s spectacular mathematics building, we had our weekly meeting of the Chebfun team yesterday. Looking around the table, I realized that the people here working with me were from Italy, France, Germany, the USA, Pakistan, Iran, Japan, and China — and that I was the only one in the room with the right to remain permanently in the UK.

Seven-and-a-half of our nine salaries are paid by sources outside the UK.

More or less accidentally, the British people seem to have voted to bring all this to an end.
