Question

How does Geometry work?

Answer 1

you sit at your desk, and listen to the teacher....

Answer 2

play with shapes like this envelope
throw in there some letters

Answer 3

or draw something like this pretending you are building
a picture cover or something

Answer 4

Honestly, i forgot how geometry works^_^

Answer 5

Apparently it works because it seems to be that we live in a logically consistent reality. If you consider the flat land of Euclid, the Pythagorean theorem has been true ever since that greek dude discovered it long ago. There's something deeply mysterious about the fact that such a seemingly simple and interesting thing should exist at all. In physics you can ask many similar questions that no one knows about common things. You start asking enough questions and you realize all of physics is just describing how things happen based on how a bunch of people have observed. And through a certain level of faith in the beauty of mathematics some incredibly fascinating physical experiments have come out. One great example of this is how we discovered that light was an electromagnetic wave was purely a theoretical discovery based upon the idea of a beautiful mathematical theory.

Ok so I'm rambling here, and I probably didn't even answer your question since I am more or less answering the question of "why does math work" by saying nobody knows. But that is what makes math so much more interesting than all other subjects. Physicists literally use the power of math to predict the future and plan events, create structures, and manipulate the matter of our worldly existence into usable tools in magical ways that we almost certainly take for granted. The fact that for most of human history there was the ability to push smaller than microscopic particles over tiny metal strings to do powerful work and vibrate to communicate invisibly through the air is sort of crazy and without math you wouldn't be reading any of this rambling, but would probably be burning a wood stove haha.

Answer 6

Thanks @Kainui

Answer 7

Kainui, lecture ;)

Answer 8

very deep^_^

Answer 9

i would like @Kainui to be my lecturer for math hehe

Answer 10

ASK @Abb0t he would know..

Answer 11

I'm just gathering some information up, I know how geometry works. I just want to know others opinions. Thanks.
