Or does the weight kinda disperse across your body because it's liquid?

>>7728387
This is the same as you hitting a tonne of water with your head, so think diving into a pool. Obviously it depends on the night you drop from
>>
>>7728395
This. If you drop it on the first night, you'll probably just get wet and cold. However, if you wait two months to drop it, this would be the equivalent of smashing head first into a block of concrete at ~60 mph.

What gives? I thought Berkeley kids were supposed to be smart, but most of them don't seem to have a solid grasp of fundamental logical reasoning, let alone the material being covered. I TA a class of about 20 students and only 1 of them seems to consistently have a grasp of the material.

I admit the course and the exams...

Hey /sci/, if you build a tower of hamburgers from Earth to Mars at closest approach, how much weight would all of the other hamburgers push down on the one on the surface of the Earth with?
>>
it depends. is it in europe. probably several gigatons.

in america? quarterpound with cheese.
>>
>>7728338
Distance from Earth to Mars in millimeters:
225,000,000,000,000

Height of one average 300g burger in millimeters:
100

Weight of one average burger granted it is only bun and burger ~330g

Amount of burgers you could tower on top of eachother: 225,000,000,000,000/100 =
2,250,000,000,000 burgers

Weight of the sum of all burgers minus the one on earth: 2,250,000,000,000*330 - 1 =
742,499,999,999,999 grams.
Translate to weight:
742,499,999,999,999 / g = 742,499,999,999,999...
>>
>>7728973
my bad, not 2250000000000*330 - 1 , it should be 2250000000000*330 - 330

Are people who try to memorize a lot of decimals of pi(or other constants) intellectually simple human beings?

Yes. Likely insecure as well

the more digits they memorize, more intellectual they are. i know the first 2 digits 5/7

Anyone else here that can do calculus in their head but can't do simple arithmetic in their head even if their life depends on it? I have all A's in every single math course including all my calculus courses but I can't do simple math really fast so I end up using a calculator
>>
i can't do long division for shit. i have to look it up every time i try.
>>
It's probably quite common. An effect of doing calculus all the time but never practicing mental arithmetics.

You just described me perfectly. First year calc is peasant tier and I can do large geometrical calculations/ complex integrations in my head but I struggle with basic addition and subtraction that a middle schooler could do faster.

This board is full of shitty threads so I am going to try to make a not shitty one.

ITT: We teach /sci/ something science or math related.

I am going to go through a basic explanation of what a Quantum Field is because I am pretty sure a decent bit of /sci/ is familiar with the basics of QM but not so much QFT.
Ok so a Quantum Field is essentially a sum of operators and wavefunctions.

Say we have a theory where the state vector $\left| {n\left( p \right)} \right\rangle$ represents the nth energy level of theory with momenta p.

Then...

this is shit

how much maths would i have to know to take a quantum mechanics book and breeze through it

You fucked up your latex OP. Besides, I don't understand any of the notation you're using whatsoever. But I have been looking for that pic for awhile it used to be my wallpaper but my computer broke so thanks for trying I guess.

23 KB,
Scientists always fall for the logical positivism meme. And they don't even realize it's a philosophical position with philosophical justifications....

They're pretty dumb to be honest. They have massive tunnel vision and because of that they don't realize their epistemic assumptions and treat the scientific methodology as axiomatic, they think it's common sense. And when someone approaches a problem with a different epistemological framework they think it's bullshit...

They're simply very bad at thinking outside of a scientific...

Hi.

Can electromagnetism be considered a force in itself, distinct from electricity, and magnetism, alone, and more than just the mutual interaction of those two?

No, I want the/an answer to the question in the OP.

>>7728022
Electricity and magnetism are just two different manifestations of the same thing. That's why they can be linked under electromagnetism.
