why is maths as a school subject nothing but difficult number tricks with no practical application? physics has equations that are both piss easy and give you answers you can use. fuck educational maths

i hate both and can't do them


I had to use algebra to solve a problem I had with a power outage while I was printing stamps with a postage machine once

> Mathematics is a part of physics. Physics is an experimental science, a part of natural science. Mathematics is the part of physics where experiments are cheap.
> The Jacobi identity (which forces the heights of a triangle to cross at one point) is an experimental fact in the same way as that the Earth is round (that is, homeomorphic to a ball). But it can be discovered with less expense.
> In the middle of the twentieth century it was attempted to divide physics and mathematics. The consequences turned out to be catastrophic. Whole generations of mathematicians grew up without knowing half of their science and, of course, in total ignorance of any other sciences. They first began teaching their ugly scholastic pseudo-mathematics to their students, then to schoolchildren (forgetting Hardy's warning that ugly mathematics has no permanent place under the Sun).
> Since scholastic mathematics that is cut off from physics is fit neither for teaching nor for application in any other science, the result was the universal hate towards mathematicians - both on the part of the poor schoolchildren (some of whom in the meantime became ministers) and of the users.


Pure math is valid in all possible universes, physics is for single universelets


you will never run a real math class

Math is useful as fuck. I use it all the time. I used the Pythagorean theorem last week when I was building a structure to protect a well-pump from rain and need to know how long to cut the boards. I'm making a game where I regularly need to apply trigonometry when determining the relative rotation and movement of things. Our educational system sucks, and they suck at teaching math in a useful way, but that doesn't mean it isn't useful.




The classroom is used to induce anxiety and reverence for experts. Math class does not reliably produce math skills, but it does reliably produce ’math anxiety’, the belief that math is out of an ordinary person’s reach, and the belief that mathematicians are a class apart.

"Professor Yum-Tong Siu, whose class began with 50 students in 2003, said he actively tried to whittle down the class size. As The Harvard Independent reports, the class dropped down to 25 students, but Siu added: "I want to reduce it a bit more." The goal: 20. "We want a group of students with similar backgrounds so we can proceed at a pace that can suit them at the same time, so they don't feel bored or over their heads," said Siu."


> arcane subjects (at least to humanities concentrators) like eigenvalues and eigenvectors
Aren't those usually covered freshman linear algebra?
