/sci/ - Science & Math

Raged so hard at the social "scientists". "But the biology is uninteresting", "the research is weak" etc. They are talking purely out of their asses not knowing the methodology or the results of research from 1980-2011. After this if I were the dean of faculty I would fire every single one of those Norwegian fucktards.

With the addition of /pol/, what is the probability that in the coming weeks /sci/ will become less shitty again?

Pic unrelated.

Hey /sci/, I'm going to go argue with my teacher on Monday, but I want to make sure I have my facts straight.
We were taking notes about accuracy, defined as how close a piece of data is to the actual value. Later in the lecture he puts an example on the board: (22.5*22.25)/2=? and asked us to solve it. Obviously we all put the correct answer: 22.375, but he said it was wrong, and the correct answer was 22.37. He said something about the fact that the decimal of one of the numbers only went into the tenths place. I was going to argue it with him then and there, but he wouldn't let me during the lecture, and I didn't have time after class.

My argument: It can't be mathematically proven that the average of the two numbers is 22.37 and not 22.375, whereas the latter answer CAN be proven. If it can't be mathematically proven it is neither scientifically, or mathematically correct, or accurate.
TL;DR: What is the average of the two number 22.5 and 22.25
