/sci/ - Science & Math

>integration by parts
>flawed
Choose two.

<div class="math">\int \frac{1}{x} = \int 1\cdot\frac{1}{x} = x\cdot\frac{1}{x} - \int x\cdot\frac{-1}{x^2} = 1 + \int \frac{1}{x}</div>

Subtracting the integral we obtain 0 = 1

Try to make a non-highschool thread. Try to ask a genuine science or math question on university level on /sci/. Fucking do it and see what happens!

I'll tell you what happens:
You won't get an answer. The thread receives 2 or 3 shitposts containing random insults or general off-topic /b/ shit and then the thread gets pushed off the front page by preschool tier philosophy quibble which gets reposted every day even though every 6 year old already knows all the arguments and is aware of the topic's irrelevance for all practical purposes.

>electricity and magnetism were unified but not the same thing

Confirmed to have very little knowledge of any higher level physics. Electricity and Magnetism are the exactly same fucking thing, this is already incorporated into the standard model of physics, Quantum electrodynamics and Quantum field theory. These are the most accurate theories ever developed, and any GUT will have to incoporate them. How can you not know about them?

The Lagrangian is a way to represent a physical system. Every fucking thing in the universe can be written as a lagrangian.

Once you have a lagrangian for your system, there are known rules to generate the "equations of motion" and all the basic physics information. The rules to generate the equations of motion, and physics, from a lagrangian are pretty fucking general. So it is very very easy to go from a lagrangian to equations of motion (and often visa verse).

1) generate a lagrangian for your system
2) getting the equations of motion, and physical constants from your lagrangian
3) PROFFIT!

>it's quite obvious that humans themselves cannot cope with so many people

Nope. We will cope just fine (not to say there wont be some struggles along the way).

Humanity will grow to the hundreds of billions and even trillions one day (we probably wont all be on earth then though). Space is a big place!

Taking Calculus atm, just finished midterm. How do common people think this is hard? I think they just never give it a shot.

Wow, what a shitty wiki post. Thanks for mentioning that. I deleted the shitty parts, and will make sure to keep an eye on it.

It is impossible to do physics, without any coordinate system in mind (or even switching between multiple systems, as done in relativity).

You can set-up the most abstract metric, and Lagragian, and start with pure theory and no coordinate system, but at some point you need to incoperate a coordinate system to make the connect between the physical universe. If you don't make the physical connection, you are not doing science or physics, you are just doing mathematics.

Do you not know the difference between mathematics and physics? Does your fail know no bounds?

On an observational level, how can I observe shit without a coordinate system? If I can;t observe shit, how can I verify a science?

What is the problem you are having?

>>2852918
Yes, there is worlds of difference. However, you will not heavly use physics/mathematics for biology, SO THEY DONT TEACH YOU IT! DURRRR. They only teach you the minimum!

As a bio/soft science person, you will not need extensive math or physics to derive your scientific conclusions. While in Physics/Chemistry you do.

>"if we let them sit there for really really long time, they would move closer and closer to each other, even the tables and the chairs would bunch up after a long enough amount of time had passed"

Nope. This would not happen on earth or a planet. Or anycase where there is anyother overwhelming "gravity potential". This would only happen if the papers where in space (with no planet around).

So, you teacher say somthing wrong. Then you try and say, she is wrong becuase of friction. You are also wrong though. Her being wrong isn't becuase of fucking friction (not the kind you talk about), it is becuase the force of gravity from the earth far outweights the force bewteen the papers.

You both suck at physics. But at least you are young and have an excuse. She should be fucking shot.
