Hi. π is a constant. The purpose of π is to use it to find circumference of a circle or area of a circle. Correct? Can you please elaborate? Can you point out any other two constants and its purpose? Thanks.

So in my future numerical analysis class the recommended book i liked the most was Numerical mathematics by Quarteroni : https://books.google.pt/books/about/Numerical_Mathematics.html?id=m-bHBAAAQBAJ&printsec=frontcover&source=kp_read_button&redir_esc=y#v=onepage&q&f=false Since i like this...

I'm a computer scientist with aspirations to apply myself to fundamental research, data analysis, or computation, in physics; And these are the books I've purchased so far but haven't read. Which order do you think I should read these? Or more generally, how should I schedule the reading of...

So you I've screwed up in Mechanical engineering courses due to a combination of personal reasons and some tough professors. I have discovered that it is possible to finish a BA in mathematics in the same time frame as the Mechanical engineering BS degree, only one semester + the summer. I've...

Hello everyone, I am currently attending a community college and at the end of spring, I will graduate with associates in mathematics and physics with roughly a 3.90(depending on the what GPA you're talking about). Physics and math are my life and I dedicate virtually all of my free time...

In multiverse theory, where it is supposed to describe ALL outcomes, a mathematical multiverse is the ultimate ensemble and there are not more levels than this, but it doesn't contain all the imaginable universes because, as Max Tegmark himseld quoted in a paper "the mathematical universe...

So I recently join an engineering course, in my pure math classes we are currently studying basic algebra, simultaneous equations or quadratics. I quickly found all this very abstract and presented as facts. Now, I don't know how to phrase this, rather than looking for a book that just states...

Hi, I've taken calculus during my engineering degree (that I'm still attending) two years ago. At that time I didn't realize the importance of calculus (and also linear algebra) so I studied it superficially. I think I'm quite good though because I had to use my calculus knowledge in all the...

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...

I think that the existence of subharmonics is also bifurcation.Is that true

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...

I am having a hard time trying to understand this transformation from lorentz:https://imgur.com/a/WYWMO (You should ignore the spanish part and just focus on the math). I can’t understand well why they turn into what you can see in the second picture, when taking really small values of x...

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...

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...

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...
