Hey, /sci/, it's /k/
We have some questions.
What are electron beams? What do they do on a cellular level? How are they made? How might they be made in, say, a well stocked apartment or home?
All I know is that TVs use an unfocused version of them and that they can blow shit up.
I'm counting on you, /sci/

According to the first law of thermodynamics, energy cannot be created or destroyed. If that is true, then where did the "first" available energy come from? If this law applies to any form of energy, then the first form of energy had to come from somewhere. If it could not be created, according to the law, then how did it come to existence?

Hey guys, do you think you can handle this problem? i dont think i can, because i don't know/don't remember the mathematical technique that i should use.
"? teachers need to correct all the ? tests from their ? classes. Destribute all the classes between all the teacher in a way that they all stay as close as possible to the mean of tests per teacher (?\?).
The hard part is, two teacher cannot share the same class! so each class that is given to a teacher must be corrected only by himself. Also, the number of tests is not equal to all classes. you have the amout of tests in each class. (use whatever variable you want for n classes)
i dont know if i expressed myself correctly, so i'll give an example.
5(?) teachers, have to correct a total of 400(?) tests from 4(?) classes.
?1 (number of tests in class 1) = 70
?2 (number of tests in class 2) =130
?3 (number of tests in class 3) = 150
?4 (number of tests in class 4) = 50
In this case, the solution where everyone is as close to the mean as possible, is to give the tests of each class to a different teacher and leave one teacher without any tests (since they cannot share a pack of tests)

Does anyone hate poorly worded/ambiguous problems as much as I do?
So I'm working on some physics homework, just mechanics stuff, no big deal, and we're doing friction. I'm given a problem where a mass travels whatever distance down an incline, right? But... how the fuck is that distance being measured? Is it the path length? Is it the actual distance traveled? Did the mass descend that far? I don't know, and it's fucking infuriating. This problem should be pretty much trivial, but NOPE, it's poorly worded and I would have to do it three times to guarantee I get credit for it. This is bullshit, I quit.
