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

Also, if n=4 then 2^4=16=0 but 0 is not 2. You can only do your trick when k and phi(n) are coprime.

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.

Where should I start? Should I learn a bunch of calculus first? I was recommended University Physics With Modern Physics (Young & Freedman) to start with and then to move to Quantum Mechanics (Bransden & Joachain). At least to start off with.

Any other recommendations or whatever? Besides college and stuff, just on maybe the order you began learning it or w/e? thanks.

Learn calculus, differential equations, linear algebra, and abstract algebra/group theory. Read Quantum Mechanics by Shankar. When they start about euler lagrange equations as a way of doing classical mechanics problems check out Give Taylor's Classical Mechanics.

If you want to go deep the Landau Lifshitz books are essential. Griffith has a good E&M book if you are only interested in learning enough E&M to do advanced quantum. Gordon Baymn's lectures on quantum are really dense, but really well summarize the most essential aspects of quantum, and teach you how to solve some really practical problems (spectroscopy/scatter/super conductivity class shit). Messiah's and Sakurai's textbooks are each good in their own ways.

You need calc 1 and maybe calc 2 (techniques of integration) for undergrad level physics books (specifically Newtonian mechanics and Electromagnetism). I used University Physics which you mention and Fundementals of Physics by Halliday and Resnick, either will do (get an old edition for cheap) but I personally liked University Physics more.

As for QM you'll need linear algebra and differential equations, both of which you should study after calculus. I'd recommend getting an old edition of Calculus by Stewart, Spivak might be too much if you've never seen calculus or if your algebra and trig is weak. Undergrad math textbooks are generally shitty money grabs, and MIT has some of their's up for free.

For other book suggestions I'd recommend looking at a university's physics courses and their respective syllabi.

A rectangular piece of cardboard has a length that is twice its width. Squares with sides that measure 1/10 of the length of the cardboard are cut from each corner and the resulting flaps of the cardboard are turned up to form an open box. A maximum of 24 cubes that measure 2 inches on the sides can fit perfectly inside the box. What are the dimensions of the box? What were the length and width of the rectangular cardboard before it was cut and made into a box?

So I now realise that my other answer doesn't really make sense because the resulting box would be the right volume to contain the cubes but not the right height. With that in mind, the solution is easy. Let x be the width of the original cardboard. The length is then 2x and the side length of the squares removed is (1/10)2x=(1/5)x. But this number becomes the height of our box, which must be 2in if the cubes are to fit perfectly inside. Solving (1/5)x=2in we find the width can only be 10in and the length 20in.

Try stating your question more clearly, if possible. It sounds more like you're not able to determine the quality of that thing because your definition of what thing is lacks the enough specificity for you to even know where to start when trying to extract the appropriate information from where and in what ways to manipulate it to give you a quantity for the exact thing it is you are trying to determine the quantity of.

Yes, but there are fewer "z" letters in Zero Places Theorem, and the space key is already one of the most used buttons. It is more economic and eco-friendly over the long run to use long and complicated words that have lots of "z" and 15+ characters.
