> tfw have exam on gauss's law on monday but am completely lost

what do bros? kms? its 20% of my grade if I fail it im fucked. Should I just start applying at factories I hear that welding is a good trade to go into these days...

It is Gauss' Law

I can relate man. I had my test on Gauss's law earlier this week. I think I did well. Physics II isn't destroying me but it is so different from Physics I. Why is it so weird? And don't get me started on Gauss' law specifically. That law seems really bullshit. I know it has been confirmed experimentally or some shit but I am pretty pissed at the universe for working like that. It just seems so arbitrary. "Oh, just put the charged object inside this Gaussian surface and voila magically you know the charge". So fucking weird. And I don't like that there are special bullshit cases like if the charged object is a piece of metal.

For context I'm a math major and it pisses me off that the best explanation I can be given is "This was confirmed experimentally". FUCK YOUR EXPERIMENTS. Fuck.
