the form of 2^(2^m)+1 makes them just one too large to use 8 bit or 16 bit binary calculations (which might be alleviated and as such is part of the interest)
And they represent the number of sides of construable regular polygons which are as perfect as you can approximate a circle in their own right, in terms of relative the quality of approximation vs number of digits needed to do the calculation.

The concavity has to change for it to be an inflection point. If it's concave up, then a place where f''(x)=0, then goes back to being concave up, it's not an inflection point.

The fact that the equation is using the variables "a, b, c, and d" and it that they are equal to zero implies that this is a 3D plane equation. Like other people have pointed out, there are infinitely many points that would satisfy this equation in Euclidean space because geometrically speaking you can place an infinite number of points on any given plane.

Are you sure you have to take that specific class? At my university there are distribution requirements, where you might have to take a year of some type of analysis class. Maybe you can change the MS program you are enrolled in to an applied math MS where the requirements are different. Even then, complex analysis is a branch of math that has a lot of real world uses, it's not like this is a class on Galois theory.

Here you are required to take 2 semesters of regular analysis, but not the complex.

complex analysis is useful for a lot of things in math. Since your ms is in math and not statistics, complex analysis is considered an essential core course, like abstract algebra or real analysis. With your PhD studies in mind, complex analysis can be useful because it gives a way to evaluate a lot of different definite integrals over the entire real line. Even for real-valued functions, we can sometimes solve otherwise impossible integrals by passing to the complex plane, taking a clever contour, and then taking the limit as the contour expands. This comes up when you are trying to find the fourier transform of certain functions, for example, or when you want to integrate certain PDFs over the entire real line. It's a useful class anon. Even if it doesn't seem like it. Lots of great statisticians were at least proficient in complex analysis.

Assume we had all the possible methods of information storage in the universe and all the resources of the universe at our whimsical disposal.

What's the largest number we could put down in some kind of recording before we ran out of universe?

So I guess the core question I'm asking is what's the most compact way to write large numbers? Is there anything that beats out scientific notation? And what's the greatest extreme to which we could conceivably take this?

There's no real boundary between "notation" and "formula". Arabic numbers might be conceived as a sort of formula which takes a vector of integers to a finite power series (a1, a2, a3, a4, ...) -> (...((a1 * 10 + a2)*10 + a3)*10 + ...))...). Likewise you can have formulas like Conway's chained arrows which express huge numbers, for which the chained arrows effectively take the place of notation because writing 3->3->3->3 in Arabic numerals is already far beyond impossible.

I would think of it as a function rather than a formula. Interpreting the conway notation as a function, its domain is sequences of natural numbers and the codomain is natural numbers. It just happens to be a function that takes larger values, and of course there is always going to be a function that provides numbers larger than the ones you would obtain with the conway notation.

In fact, natural numbers and all other mathematical objects are functions in some sense. You could think of the number 5 as being a class function from the set theoretical universe V into 2, that takes the value 1 on 0,1,2,3,4 and is 0 everywhere else. The empty set would be the function that takes the value 0 everywhere.

This doesn't work depending on what theory you are trying to formalize math in. For instance in ZFC you can't talk about a function f from V into 2, or V at all for that matter. So, everything is a function and whenever we write something it is a description of the desired function. Even the text itself could be considered a function.

We can reason about an arbitrarily large numbers using symbols. I could say that n is the smallest number that can't be written out in arabic numerals using all of the resources of the universe, and then talk about 2^n. I couldn't do this in the theory of arithmetic, because there is no way to formalize the idea of the amount of data stored in the universe within the theory. If you moved to a more powerful theory, then another problem occurs.

We don't really know what the universe is, how big it is, or other things that we would need to know to get a real answer. So to answer OPs questions:

We don't know what the largest number we could write down is because we don't know enough about the universe, and it depends on the type of notation we use to write down the number. There is no most compact way to write large numbers. There are many ways that you can beat scientific notation. You can take it as extreme as you want.

The largest numbers we have ever talked about come about from sentences like "The smallest number than can't be expressed in 100 characters or less by a formula of set theory". Y…

Hi guys,

Wondering if anyone could point me to an introductory level book on Math that teaches primarily by showing how to visualise the math so that I can understand HOW it works (as opposed to just memorising the equations/procedures and accepting that they work).

I'm thinking of going Feynman's Lectures atm, but am wondering if there's something better you guys might recommend.

Again, would like it to start at the very basics if possible.

Thanks and Jesus.

I am taking a class in abstract algebra and was getting ready for a test and noticed a pattern that has popped up when shows how to represent all polynomial functions in a ring that map from Zmodn to Zmodn. What I (think) I found is pretty much why when you have some value x^n it can be replaced with x etc. Pretty much showing why there is only one way to represent all the functions withing the ring due to not being able to have any x raised to something larger than n-1

As somebody who dropped out of studying math after 3 months, don't sweat it.

That said high school math is very different to academic math. You won't be learning calculus or algebra, at least not at the uni.
However you learn about proofs, what you need them for different kinds of proofs and how they are done. You'll need some algebra to follow the exercises and examples, but nothing really substantial.
But you might discover that Math in it's academic form is an ivory tower and if you want to do anything but being a researcher you'd have to find your own interests to do something financially worthwhile in life, which will be if you really like math seem stale in comparison.

If you want to learn something exciting that relates to the real world get out asap.

An undergraduate degree in math almost always requires taking a sequence of calculus classes that lead in to proof based math. There are many people that get undergraduate degrees in mathematics that go on to work in the private sector successfully. It is inaccurate to say it's in ivory tower field, that is only accurate if you want to become a professional math researcher, which even a large portion of those with math doctorates don't pursue after their thesis.

OP if you're interested in math stick with it. There are jobs out there for people with math aptitude. You will probably have to learn how to program.

Math related jobs are high satisfaction because they generally pay decently and the process of learning various fields of mathematics can be really mentally rewarding depending on your personality.

On the other hand, if you want a more streamlined career progression that follows a pipeline you may want to choose a more professional style of program. If you study math and don't want to become the ivory tower researcher, at some point there is a transition you have to make in to doing real world things that causes even the most intelligent people to "fall off the wagon" sometimes.

I am certain i am missing information so i appeal to you brainy smarties to educate me However this also may be a physics questions. I dunno.

Do curves actually exist? Meaning at the smallest point possible (I would assume planck length) would it not be a straight line from point A to point B then a second straight line from point B to point C etc etc? Only upon pulling back far enough to no longer see the individual points does the curve appear?

Any model of reality discussed in language is "sort of" discrete because language is a discrete medium. However, to the extent that language can describe the idea of continuity at all, it can also encode it in a model of reality, so there is no comprehensible sort of continuousness which cannot also be a property of the Universe. As such it makes no sense to argue that the Universe is discrete because the models are discrete, because "the models are discrete" is not a meaningful statement: all possible models are discrete because the means of communicating them is discrete. Effectively the argument becomes that no continuous universe could contain beings which communicate about said universe in a discrete language, which is clearly silly.
