I wanted to give my head a bit of a rest from the world of loon that is all around us and retreat to the relative sanity of something concrete and rather beautiful.
Geese and ducks, flying to warmer climes is what I see when I see a vector. Funny thing about how most cities are laid out on a Cartesian grid, (with notable exceptions, like Detroit, where I am from). The parts of Portland OR (where I now live) laid out in a wheel fashion continue to vex my poor directional skills after 30 years. Seems we are better are grids than diagonals, or they are just cheaper to design because angles create problematic lot shapes as well. On Detroit planning history, another small diversion https://detroitplanninghistory.weebly.com/1700-1900.html
Another good journey back in time and mental attention. Thanks!
Any recommendations of books which would help refresh the mind on mathematics? A few years ago I took a series of pre-calculus courses at the local junior college and was amazed at how much I'd either never learned or forgotten.
I then made it through the first semester of calculus, but got side tracked by life, before continuing the journey. I'd like to try it again from home, without having to endure the current asylums known as colleges.
If you are referring to the type of logging that involves trees and chainsaws, most definitely. Determining the height, fall zone, adjusting for lean or limb weight, manipulating fall direction and speed, all use vectors and the the calculations of their combinations.
Chainsaws, wedges, axes, bowsaws, handsaws, levers, rope and tackle - yup. Thats the works.
Old lady what owns a plot of forest next to my house asked if I could take care of some old spruces that have died and dried out still rooted, in exchange for taking the wood as firewood. Being more neighbourly than miserly, of course - plus it's fun.
Only problem is, two of them have fallen so they're leaning onto others, making it a real "math-problem" so to speak.
I just find it funny how us humans can do practical stuff that it takes complicated (to me) math to represent abstractedly. On the other hand, practical came and always comes first - "Erst kommt das Fressen, dann kommt die Moral" as Brecht said.
Like a glass of neat and very cold gin
I am looking forward to your series on quantum mechanics. Yay!
Goldilocks. Not too little, not too much.
Please carry on.

I love the way you teach this. 👍🏽

I'll have to re-read this, it's a bit beyond me at first read-through.
On the other hand, I'm pretty sure I use all this stuff on a daily basis when I'm logging.

Ditto. I’ll reread it slowly.
