Yes, I loved the sound of those chains at 6000rpms, mine was a 4 speed with an overdrive handle on the steering column, had to hold the clutch in, move the handle, and wait for the electric shift to get it in OD, didn't go the other way, to get out of it you had to shift into neutral then back into 4th, took a little getting used to!
I used arithmatic and right angle trig in the machine shop.
I was an aerospace engineer for 35 years and now teach an aircraft design class (and one on aircraft turbine engines) at a local university. It's a great retirement job; they pay me to talk about airplanes! I also design, build and fly RC airplanes for a hobby, so I use math a lot.
BTW, I see that you're in Washington state. I got my last speeding ticket there 5 years ago. It was a beautiful sunny morning on US 101 south, about an hour from the Oregon border. It was a slight downhill through a beautiful series of sweepers and I was getting into a nice easy rhythm at what seemed like a moderate speed. One of your fine state troopers got me at 69 in a 55 zone. Considering the conditions and my car (the tires are rated for 186 MPH), I could have easily been going 20+ MPH faster with some margin left. Oh well.
