In answer to one of BertrandRussell's questions from yesterday, G&T is not a different way of saying very good at maths. It can be any subject. Its just that maths is less subjective and more measurable which means that its easier to see and define progress (and know when it has halted).
(I suspect Bert will think that as the conversation has turned to maths in the last few hours, it proves her right to have been suspicious!)
Given your choice of username, Bertrand, I am surprised that you aren't more enthusiastic about maths-related discussions. Maybe you chose it for the political persuasion instead?
Bertrand Arthur William Russell, 3rd Earl Russell, OM, FRS was a British philosopher, logician, mathematician, historian, writer, social critic and political activist.
