I watch a lot of things about the ancients and I don't mean Jerry I am talking about the Incas and the Azteks and many other cultures and marvel at what was accomplished. I don't believe that it was accomplished with primitive tools and I don't know if we will ever know in the short time I have left.

Hotrod, Dad always preferred a # 1 pencil. A friend of mine can barley read but give him a pencil or welders soap stick and there is no angle that he will get wrong. Ed

I agree, #2 pencils are too soft. Constantly sharpening them. However, using a knife edge, limits accumulated 1/16” errors multiplied by the number of times measurements are transcribed. Just saying…

I have a lot of math that was learned before there was such a thing as a hand held calculator. Did have a slide rule. In building cars from chalk marks on the floor trig is the most useful, vectors, geometry, and sometimes calculus fall further down line. With that said, I was never GOOD at math. I have to follow step 1-2-3-4-5 just like in the book while people good at math can jump from 1-3-5, etc. Now we have computer geeks that can can design the whole thing, give a dead accurate material list, and even show the finished machine with the suspension moving through its travel (example #1) and each component has its own color. About the only thing my old time math does now is wow the cashiers when I have the exact amount of the bill, including tax, laid on the counter before they hit the total button. If anyone needs to know the square or cube root I can do it with a pencil and a l-o-n-g piece of butcher paper.

One day, my college boy genius son decided that it was time to put his know-it-all dad in his place, so out of the blue without any context, he asks me, "Tangent equals opposite over what?"
I barked out, "Adjacent!" without hesitation.
His jaw about hit the floor, his shoulders slumped, and he slunk away, dejected.
I never took trig in school, but I did have a roommate 40 years ago who had, and he apparently also felt that I needed to be brought down a peg and had asked me the same question, which of course I did not have the answer. He smugIy uttered the correct answer. I called him a name which questioned his/her "orientation" and I never forgot that bit of trigonometry.

Evan, then they still get it wrong because of expediency and cost factors. A prime example is the GMC Canyon that the timing chain needs to be changed at 95000 miles and the whole front assembly needs to be removed at a cost of around $3000.00.

Tom,

That is good that you took the class regardless of your back row status. Math is a tough subject to teach that few people excel in instruction as it is so abstract. Just think of the "few" good math teachers that you had in your education, they are a rare breed. A practical application as in putting timber frame buildings together is a fantastic way to learn math.

We look forward to seeing your finished project.

Paul

One of my pet peeves when I was in the classroom was having to teach high school students basic skills in math, physics, geometry and chemistry that they were supposed to have learned in elementary and middle school, before I could apply those principles to teaching auto mechanics. I guess the ghetto gangbangers the counselors sent down the hall to the auto shop to keep them away from the "good" students never had a need for any real education before they got to me. Surprise! Some of those wannabe thugs are making a good, honest living with the skills I managed to teach them, and some of the "Advanced Placement" kids are baristas at Starbucks these days!

Just like Mark Twain once said, "Don't let schoolin' interfere with your education. "

I think calculators are the bane of mankind, they're just crutches that make the population dumber. Full disclosure, though, I do use one from time to time.
I once took my younger daughter to the grocery one morning to buy stuff for breakfast when she was 4 years old. She picked up package of potato patties that had six of them in it and declared "That means we each get one and a half". We still talk about that moment, calling it "food fractions". She can do math in her head and works as an accountant 30 some years later.
