Now, someone is saying that they are seeing it buried down in some neat, newish stuff.
Why do I care? I dunno, after I got outta the A.F., and realized that I couldn't do math for diddly, I started practicing figuring percentages, doing addition, multiplication, in my head. And played with prime numbers on paper, and have forever been frustrated by higher math, starting with algebra, but trigonometry was like a fun class,
Anyway, I like science. I think it's fair to say that every mechanic is a scientist. But,not all scientists are mechanics.
