As a quilter I use the Pythagorean theorem to figure out how many triangles I can get out of my fabric and how big to measure them. Once I had a pattern for a skirt that wanted right triangles of a certain length on the c side so I used it to calculate the a and b sides

The Pythagorean theorum has a lot of real world applications in architecture. For example, it's useful for designing staircases, since if you know the height of the upper floor, you can calculate the length of the staircase for any given footprint.

If there s 1 hole in the straw and pinch one end and you still say there s 1 hole, then you know the answer is there was 2 holes.
You can t take 1 away and still have 1, you d be at negative 1.
Don t over think it!

We have an outdoor hot tub.
I had to calculate how much cholrine to add. And thus needed its volume in liters (or dm3.
First time I ever had to bust out pi IRL, and I only needed to wait till I turned 40!

Euclid, Euler, Einstein, and this guy Ellenberg. by deductive reasoning, if your name starts with E, you may just end up with some theory/constant named after you if you pursue Maths/Science. LOL

[Geometry] is the only part of math where you're asked to prove something.
Number theorists: Am I a joke to you?
war flashbacks to Abstract Algebra
(To be clear, it's fun, but hard)

When he mentioned the super hero movie not inventing the tesseract, I angry-scrolled to make sure A Wrinkle in Time was mentioned, just as he said it.
reply

The straw hole one is crazy. My answer was two holes tho. Also I wish I could understand shapes in a 4 dimension. It makes no sense to me.

B. s most useless stuff I got stuck in my head wish I would have taken wood shop or metal shop learn how to use tools do useful things.
reply

You cannot come up with a use of the Pythagorean Theorem? Then you are not an Engineer. I use it daily in most of my designs.

Pretty sure he is the first non-german Person, that i've ever heard to pronounce the name Einstein 100% correctly. Neat!
