I can't into Maxwell's Equations. I can get through the math just fine, but I am struggling with the intuition. I can picture Gauss' Laws so I guess my real issue is with the intuition for curl, and not divergence.

To gain intuition for curl, just curl up in a ball and cry like the pathetic mother fucked you are

Or go to khan Academy

Curl is how much the field looks like a whirlpool. Divergence is how much it looks like a fountain.

Does /sci/ fully understand theories/formulas? And if so, how do you do it?.

For eg, when learning calculus, we are told to bring the power down and reduce it by one.

Or in RSA Cryptography we understand that plaintext can be encrypted with a key and can be decrypted with another different key.

Do you understand why it is done that way or do you just follow the instructions. Do you understand the principle behind it?. Or is it just me?...

I did take discrete math where we did some proving using MI, truth table, contradiction, etc... but when suddenly presented with a topic that you have no knowledge of, how do you understand it? Or rather than, how did the person that came up with the theory?

What background knowledge in math do I need in order to learn PDE's, Complex Analysis, Finite Element Method, and Numerical Methods.

Sad to see that in the high ups of our society we're still lead by people obsessed with the human illusion.

The obstacle this man faces whenever he begins to question genes and alleles are solved by understanding a human as a chemical reaction with an attached observer. He is looking for "people" who do "things". When will the image be molecules that have attained a human form, and not a human with molecules at his disposal...?

He makes statements like "what is a good rower" and it makes me wonder if he knows "boat"...

I'm sorry I am bad at communicating myself that is not the opinion I tried to portray. There is absolutely free will and being made out of molecules is what gives us the ability to have that.

The "made out of molecules" part is just what it will take to get people over items and career paths as defining objects. You can't make yourself think things like a boat, or a paddle, or yourself, are outside of the "molecules" you use to measure everything else.

Did anyone else go to a university of a lower standard than what you could've gone to? I had the best grades in my school, better grades than almost anyone who goes to private schools even though I went to a regular school, and had good enough grades for any university in my country. But I had zero advice about the importance of university rankings, the worth of degrees etc. I picked an engineering degree at my hometown university. It definitely wasn't a disastrous choice in terms of career (respected subject, plus a university ranked in the top 150 of the world) but...

If you're so smart you'd realize that formal education is primarily about purchasing credentials. The education portion of it is a distant second, it's only there along with testing to screen out retards so the credentials still mean something. If every degree required you to know the full width and breath of a certain subject matter, you'd be in fucking school until you were 55 years old.

The worst combination:

You are forced to become friendly with a group of people (that may or may not rotate shifts at ungodly hours) that are 100% confirmed normies that went to college and enjoy a white collar lifestyle. You have to work in pairs and teams for long shifts and constantly watch one another and verify one another's work.

You MUST be part of the pack and you MUST love football...or else you are a weirdo.

Damn I want this to be a lain thread, but I just find statistics boring. I just skimmed the first link, but that's all raw/processed data and some unabridged conclusions. I understand both that the full explanation is neccessary to understand the information, and that nobody in his right mind would write a shitty webnews article to summarise it, but I won't waste my time trawling through all those words just to find out a statistical conclusion about memes.

from the chain rule we have

\frac{\partial h(x))}{\partial x}=\frac{\partial f(g(x))}{\partial g(x)}\frac{\partial g(x)}{\partial x}

So what does /sci/ think, are Newtonian forces real, symmetrical and non-causal relations? Or is this view too anti-Humean to the extent that it defends the existence of forces as external relations irreducible to spatio-temporal ones?

This is sci, not philosophy. Sci only cares of the model works and predicts things. Metaphysics is a branch of philosophy that is basically untestable.While metaphysics is semi-import, particularly to early physics, most 'metaphysics' of our time has to to with attempting to map mathematical assertions into the quantum world.

A formula I created. Can any anon tell me if it's original? I only used my math notebooks, pencils (pens too) and calculator and never learned this in school so I don't know if it's original. I don't even know if it's in proper format actually. Anyway, that's the factored form I guess. (That's just the smallest formula I've made.) Also, if unoriginal please link me to where I can learn more about it.

I guess I'll give a quick example of it in the case that I wrote the formula wrong

Lets say you wanted to add 4 numbers together (each with the same amount of numbers between them). So lets say 7 and every 8th number after that. 7, 15, 23. 31, all squared. A would be 8 (Since that's the difference), B would be 1 (Since we want 7, and 8-1 is 7), and N would be 4 (since there are 4 numbers).

i increases by 1 every time the function happens.

(8(1) - 1)^2 + (8(2) - 1)^2 + (8(3) - 1)^2 + (8(4) - 1)^2

Is the same as 7^2 + 15^2 + 23^2 + 31^2
