Both my parents were accountants, my brother has his PhD in mathematics, I never made it past entry level college math. I've always respected math and logic immensely but never "got it." I feel my interest in biology, astronomy, and computing are handicapped by my general ineptitude in math. Carl Sagan's Cosmos explain...

Wednesday, 21 December 2011 Hello Mathematics ! :) Hi. I've never liked math. I hate it even. Every time I get stuck on a math problem and can't figure it out, I want to crumple the stupid piece of paper and throw it across the room. Instead, I take a deep breath and try again, but in the end I still don't understand...

Quotable: Bad at Math There's a tendency for adults to label the math that they can do (such as identifying patterns, choosing between competing offers in a supermarket, and challenging statistics published by the government) as "common sense" and labeling everything they can't do as "math" — so that being bad at math...

About Me Tuesday, June 30, 2009 On the absurdity of number Are numbers just a useful fiction, or are they real things that exist?
