There's only 1 solution to the d.e in that region. When you apply the boundary conditions you see there's no transmission or reflection going the other ways.

All of this is theoretical though because there's fine and hyper fine splitting which can cause degeneracy depending on the states

>>8973401
Could you elaborate a bit more?

>>8973239
why don't you read it and find out?

god would punish you

>>8973234
It would be pretty much incest

>>8973234
How do you make a clone of the opposite sex?

>>8973213
It is a concept that is often thrown around hastily but that doesn't mean that instincts are bullshit.

>>8973213
no, just way too broad. your entire brain and body amounts to complicated compounding of instincts, or trigger-actions.

>>8973213
The sum of all of my biological sensors tell me no.

go look at the formula for area of a triangle

>>8973217
This.
Use heron's formula + transcendentality of pi.

>>8973209
No.

This problem is equivalent to squaring the circle.

We've never seen evidence of intelligence in your brain anywhere either, and you're probably around 20 years old. If there was any there, we'd see it in your posts. Furthermore smartposts are the easiest to see since most of /sci/ is shitposting, and we haven't seen one.

fail/10

>>8972969
that's literally what the class is called
https://is.cuni.cz/studium/eng/predmety/index.php?do=predmet&kod=NDMI002

math that is more concerned with deeply understanding/proving a result rather than using a few specialized results to perform simple computations

>Is Beamer a meme?
No, if you want to be taken seriously doing presentations in mathematics/physics and to some extent computer science and chemistry you should use beamer

>I feel that it would be extremely inconvenient to use it to format something so visual as presentations
If you know what you're doing it isn't.

>>8972871
As a continuation on this,

Using beamer over something like canva or powerpoint adds a level of professionalism that you just can't get from the former two aforementioned technologies. It is tailor made to present mathematical text in ways that the other technologies are just obviously inferior in.

There is something to be said about the learning curve involved in beamer. You have to know latex, but it you already do, it's a trivial amount of work. If you don't, there is definitely a learning curve.

Don't use the default layouts, they are horrible.

Slides are mostly boxes with text inside, bullet points with text, formulas and images.
The only thing tricky are images. Tikz is often handy, but if your picture is static use inkscape and export into pdf.

Depends on the career. Knowing high-level math/physics will always be useful since you can learn more advanced concepts that your peers have a hard time understanding. For most people you only use basic arithmetic and logic, there's not much else. The hard part of jobs is being able to understand the language of the system and being able to work with various programs/programming languages. But if you really want to do great things you'll probably need some type of advanced math/physics knowledge that will help you solve a problem no one could solve efficiently before.

I'm gonna go ahead and guess you're a freshman strugglig in mechanics and calculus thinking "you'll never use it again," and if that's the case, you're deluding yourself. It's true you won't use a ton of calculus outside of r&d, but the computational thinking you're meant to takeaway from those courses is rehashed in every single course you'll take in engineering and it doesn't get easier, unless you maybe buckle down and stop making excuses like "I'm bad at math." If you really are "bad at math," you probably shouldn't be in any hard science... (cuz you're a brainlet)

Am in diff eq and thermo at the moment. I started pretty much having trouble once I got to Calc 3 but diff eq just feels like its ripping me a new asshole

I am a man of little book learning and was always under the impression that dark matter is ordinary matter that has avenue to observe it, such as a larger body near by to affect it? how wrong am I?

>>8974760
Dark matter is matter that doesn't interact with electromagnetic radiation meaning it doesn't emit light so you can't see it
