Agreed. You’d be surprised how much you use.
Most importantly, having more knowledge teaches one to THINK.
I know I haven’t used my math and physics directly so much as an engineer, but it forms my “instincts” whereas other people might not have that. I know there are some things I take for granted now that I didn’t before college.
I couldn’t agree more. When I make microprocessor based lab instruments for a chemist, biologist, or geologist, a little knowledge works out a lot better than a blank stare.
“Pythagorean theorem”
Perhaps it has something to do with India’s average IQ which is 76.

I went to an inner city high school that was 93% black but only had one black student in my Regents math classes after like 9th or 10th grade. It seems to require a minimal IQ in order to understand certain concepts beyond multiplication and division. Once you start getting into trig and advanced algebra the herd starts to thin out. Not everyone is good at abstract thinking so India figures why waste their time on it for those unlikely to ever use it. This policy might be coming to America before too long once all of these illegal immigrants start filling up our schools.
