> I recently learnt that the Toeffili and Hadamard gates are universal for quantum computation. The description of these gates involve no complex numbers. Hmm, these are matrices so essentially complex numbers?

Correct. You can pretty much always replace complex numbers with 2x2 matrices.

I hate “learnt”

What do you hate about it?

It sounds like an "ain't" version of learned. I just read this from Grammarly:

"Learnt and learned are both used as the past participle and past tense of the verb to learn. Learned is the generally accepted spelling in the United States and Canada, while the rest of the English-speaking world seems to prefer learnt."

Apparently I'm an egocentric American.

Some kind of focus would do this young man well. Also thinking how to turn that all information into action or outcomes.

What would you recommend I focus on? I personally work on compilers as part of research, so that's "focus". My current broad goal is to learn all the parts of math that I feel might wind up becoming useful for applied math in the next 50-60 years. So no arithmetic geometry, yes algebraic geometry.
