What should the Mathematics requirements for Physics degree really be?
The usual official requirement is three semesters of Calculus, and then one more combination course which combines some linear algebra and not-too-complicated differential equations. Often the Physics majors, at least for...
Chaos is when the waveforms become aperiodic. I think bifurcation is the phenomenon inclusive of chaos and in addition, it is also termed for situations in which the waveforms become n-periodic.Does bifurcation include period-n phenomenon as well as chaos? From period-n it means that still the...
Is Set Theory a Construct? If yes, then what else are Constructs in Mathematics? Some website defines the word Construct as "something formulated or built systematically". I want to understand the meaning of the word Construct. Is the word Construct in mathematics same as the word Construct in...
I'm currently in my first year of a physics program and keep finding myself enjoying mathematics more simply because it makes more sense. I understand everything the teacher goes through but when it's mechanics in particular I simply keep coming to a stop when doing practice problems. I simply...

Hi,
So I am currently a mechanical engineer working in aerospace designing and testing different interior assemblies, video arms, meal tables, etc. For a while now I have been thinking that this field is just not up my alley. I probably use Creo for about 80% of my time while the other 20% I am...

I was out and about today and observed a dog walker playing frisbee with their dog. I noticed the frisbee gliding gracefully through the air as the dog jumped to grab it, clutching the ring-like disc in its mouth.
It got me to thinking about airflow over the disc, the lift and drag properties...
Hello
I’m 21 years old and recently got accepted to start a bachelor of science degree in physics. This will be starting next February.
I had left school at 17 due serious health issues so since school I’ve worked and also traveled to multiple countries, which for me was amazing.
In school I...
Clearly math is a product of human thought. But is there a prior reason for this?
A possibility is that math is a byproduct of basic information that we obtain from nature, where that information come in the form of ideas in which we have to sort out into something more rigorous.
We absorb...
Hey all, I'm a student in university who wants to Double Major in Computer Engineering and Physics or Mathematics. Ideally I want to get some time in working on quantum computers and some time in working on advanced AI, so one of the big things I want to do is pick the community's brain on...
Hi everyone, I am trying to learn the underlying number theory concepts behind cryptography, and I was wondering if anyone knows of good resources for learning about number theory as applied to cryptography. I was hoping to practice writing proofs as well. Thanks!

I was browsing the Play Store early this morning looking for a quality app that would allow me to practice and learn various mathematic topics on my mobile device. Surprisingly, none of the results were very good. There were a few basic "flash card" type applications with basic arithmetic, and...
This might be a naive question, but I were to ask you to briefly explain the ultimate foundation of mathematics in a formal manner to get to at least, say, the natural numbers, how would you do it? Where does it all begin? I would say that it begins with set theory, but in studying set theory it...
Sorry for the wrong prefix, but it is the most appropriate one that I could have chosen.
I have been for long wondering if mathematics would be considered a discovery about the universe or an invention of the human brain. If it is a discovery, then math is the universal language of the universe...
Hi, I am currently an undergraduate student and I plan on taking advanced math courses such as Abstract Algebra, Real Analysis, Complex Analysis, etc. There are two courses which I think could help me prepare for the courses above as they are proof intensive: discrete math and bridge to advance...

Hello.
I came across a Quadratic Equation that looks like this.
5x2 + 4x + 9 = 0.
The '5' in the above equation is called Quadratic Coefficient.
The '4' in the above equation is called Linear Coefficient.
The '9' in the above equation is called Constant.
The 'x' in the above equation is called...
Common Core is evil. Everything is about funding and exams. One of my nephews came home with a math question that my brother could not answer. My brother is an IT Specialist for Western Union. He knows math but not Common Core math.

Hey guys I figured out something new about color theory in additive color mixing.
So, the primary colors in additive color mixing are R, G, and B (Red, Green, and Blue).
The secondary colors are C, M, Y (Cyan, Magenta, Yellow).
Using basic knowledge we know that
R + G = Y
R + B = M
G + B = C...

I took some physics course but i never could be that serious because I had some difficulties first and it kinda get snowballing then I failed/stopped. So, i want to catch-up/(revise??) undergraduate mathematics (physics). So, i have a summer to do that i think, i can catch-up...
Hello. I have been looking into trigonometric identities that helps to simplify a question in mathematics. But the question that I have is, why do I need to simplify a question?
For instance:
Sin(x) * Cos(x) means Sin(2*x)/2.
I have no answer that tells me why I simplify Sin(x) * Cos(x) to its...

Why ratio in external division is negative?
I have answer for how it is negative but not why?
X = (mx2+nx1)/(m+n)
⇒ (mx2+nx1) = X(m+n)
⇒m(x2-X) = n(X-x1)
⇒(m/n) = (X-x1)/(x2-X)
From the above equation we can conclude that when division is...
