...in my job, I do a lot of math. It's kind of needed, as you're machining shapes and determining locations in 3D and whatnot. In any case, I was talking to my dad (who was a machinist for 30 years before me) and he mentioned that he wasn't a fan of regular calculators as they used to much time.
"What did you use, then?" I asked, expecting him to say that he was faster when doing the math on paper.
"I had a calculator that did Reverse Polish Notation. The order of the numbers and signs is different, so you don't have to use parentheses."
So I looked it up, and it blew my freaking mind. Why people aren't using this I'm not sure, because it basically just seems so much easier to me.
So my challenge to you math and science folks is...Have Reverse Polish Notation in common use. And predict the effects!
Game on!
