This post gave me a sensible chuckle.

I’m currently double majoring in math and CS (my school well ranked and a research uni, so it’s heavy on theory and on low abstraction system design). I’m gonna be taking graduate classes next semester, have a research position, and I have intent to do graduate school, probably for theoretical CS.

The thing is, after doing my physics requirements (a year of classes plus labs), auditing some other classes, and then taking a quantum mechanics class from our math department, I now know I really like physics and the mathematics of physics. Of course, I love math and CS too. Is there anyway I could be able to be able to do a transition or interdisciplinary work with math, CS, and physics that isn’t just writing equation solvers and scientific software. I’ve heard of really cool research in quantum information and black holes via complexity and algorithms.

Is there any way that I can eventually be able to study physics? I don’t mind if it’s a bit roundabout and I have to work a bit out of my comfort zone to get in on the community.

I want to get a PhD in subject that allows me to go to the best graduate school possible. I want funding and the weight of good training from a good school. I’m willing to have my PhD title be different than physics if it allows me to be more flexible in what I want to study down the line

Physics is like a rockstar position that doesn't pay. Most good physics programs are smallish, and strapped for cash. Good physics jobs are typically found at national labs, which are government owned (a mixed bag). Competition can be fierce in both academia and "industry", but once you snag a position, you're good to go (assuming you are in it for the science, and not so much a kush lifestyle).

I personally struck a compromise by going EE. Maxwell's equations are my bread and butter, but our lab also dips into quantum systems. It's seems a lot like a physics program (because we do basic research), but we aren't asking ourselves "what's the point?" at the end of the day; we build cool shit.

A PhD is generally seen as proof that you have demonstrated the ability to do independent research. Most people stick with their field because that's what they have specialized in, but if you decide to change fields, a competent PhD should be able to seek out and learn new information. Of course, a major change in fields is challenging and rare, but people have done it. More commonly people flow between related fields like Physics/Math/Engineering/CS. All good research is at the boundaries.
>>
>>9877496
I see, that makes a lot of sense. I figure that by the nature of the problem and the nature of research, there isn’t a rote, reassuringly simple answer, but an answer exists and it’s been done by multiple people in multiple ways.

I definitely see the appeal and actually might want to build cool shit in the future; I love how programs work and love everything they represent, but I’ve also felt a push for being able to make physical things as well (which is usually relegated to a hobby; I play around with my soldering kit and CAD/cadence on the weekends). I definitely do think that the most interesting research breaks boundaries between fields.

I think really, I want some sort of confirmation that if I go in for CS (theoretical, mathematically charged, and derivation/proof heavy CS), I won’t be laughed off by people in other fields by wishing to migrate or to see the other side. Maybe all the /sci/ shitposting is getting to me. At the end of the day, I want to be able to study what I like without having any qualification getting in the way.

Simplified Proof of the Twin Primes Conjecture
Sorry if formatting is all messed up, but I attached the pdf so that should work.
Background: Since deriving a Twin Primes proof in 2016, I have sought to simplify the proof and make it palatable to a larger audience. I rewrote it a few months later, adding some info, but it was apparently still not approachable enough in written form. A year later, I distilled the proof even further but didn’t deem it worth another rewrite at that time. That changed recently, when I understood another simplification in the process, one that should allow me to more rapidly, clearly, and concisely show that there are indeed Infinite Twin Primes. This change in approach gets directly at the heart of the issue and reduced my proof from “pages to paragraphs”. With that background, here it is.
Proof:
Given 1: All Prime numbers are Odd numbers greater than 1, except the 1st prime, the number 2.
Given 2: All Odd numbers are either Prime, Composite, or the number 1.
Given 3: All Odd Composites can be given as the product of 2 Odd numbers greater than 1.
Therefore: Primes are Odds that are not Odd Composites or 1.


Therefore: A Prime P, which is an odd number, cannot be equal to the product of 2 Odd numbers greater than 1.
Given 4: An Odd number greater than 1 can be given as 2a+1 for a = 1,2,3…
Given 5: The 2nd, or greater twin, in a Twin Prime pair, is equal to P + 2.
>>
Equation 1: P = 2a + 1 ≠ (2n + 1)(2m + 1) for n = 1,2,3… and m = 1,2,3…
Equation 2: P Twin = 2a + 3 ≠ (2p + 1)(2q + 1) for p = 1,2,3… and q = 1,2,3…
Therefore: Equation 1 gives the values that a 1st Prime number cannot be.
Therefore: Equation 2 gives the values that a Twin Prime cannot be.
Rearrange Equation 1 for a: a ≠ 2mn + m + n Surface 1
Rearrange Equation 2 for a: a ≠ 2pq + p + q – 1 Surface 2
Therefore: If (a) equals an Integer value that does not appear on either surface when given Integer inputs m, n, p, and q, then 2a + 1 will be a Prime, and 2a + 3 will be a Twin Prime.


Therefore: If there are infinite values (a) equal to an Integer value that do not appear on either surface when given Integer inputs m, n, p, and q, then there are an Infinite number of Twin Primes.
Conjecture: There are infinite values (a) equal to an Integer value that do not appear on either surface when given Integer inputs m, n, p, and q, and therefore an Infinite number of Twin Primes.
Given 6: The equations for Surface 1 & 2 show that Surface 2 is actually just Surface 1 slid down by 1 unit on the Z-axis (technically labeled a-axis if you prefer). The values output for Surface 2 equal the values on Surface 1 minus 1.
Values for surfaces 1 & 2, for m, n, p, and q equal to 1 through 15
Rearrange Surface 1 for m=1: a ≠ 3n + 1 Surface 1 Row 1
Rearrange Surface 1 for m=2: a ≠ 5n +2 Surface 1 Row 2
Rearrange Surface 1 for m=3: a ≠ 7n + 3 Surface 1 Row 3
Rearrange Surface 2 for p=1: a ≠ 3q Surface 2 Row 1
Rearrange Surface 2 for p=2: a ≠ 5q +1 Surface 2 Row 2
Rearrange Surface 2 for p=3: a ≠ 7q + 2 Surface 2 Row 3
>>
Conclusion 1: There are infinite values (a), equal to an Integer value, which do not appear on either surface’s row 1, namely a= 3n + 2.
Therefore: For any 3 consecutive numbers possible to show up in row 1, Surfaces 1 & 2 will only remove 1 or 2 of them, depending on where you start the run of 3 numbers, but will always leave at least a 3rd.
Conclusion 2: There are infinite value sets (a), with Integer values, in groups of 3 Consecutive Numbers, which do not appear on either surface’s row 2, namely a= [8,9,10], [13,14,15], [18,19,20]…
Therefore: For any 5 consecutive numbers possible to show up in row 2, Surfaces 1 & 2 will only remove 1 or 2 of them, depending on where you start the run of 5 numbers, but will always leave a value set with at least 3 consecutive elements, which will in turn from Conclusion 1 leave at least 1 acceptable value for (a).
Conclusion 3: There are infinite value sets (a), with Integer values, in groups of 5 Consecutive Numbers, which do not appear on either surface’s row 3, namely a= [11,12,13,14,15], [18,19,20,21,22], [25,26,27,28,29]…
Therefore: For any 7 consecutive numbers possible to show up in row 3, Surfaces 1 & 2 will only remove 1 or 2 of them, depending on where you start the run of 7 numbers, but will always leave a value set with at least 5 consecutive elements, which will in turn from Conclusion 2 leave a value set with at least 3 consecutive elements, which will in turn from Conclusion 1 leave at least 1 acceptable value for (a).
Therefore: For any 2r + 1 consecutive numbers possible to show up in row r, Surfaces 1 & 2 will only remove 1 or 2 of them, depending on where you start the run of 2r + 1 numbers, but will always leave a value set with at least 2r - 1 consecutive elements, which will in turn from Conclusion r-1 leave a value set with at least 2r-3 consecutive elements, which will eventually in turn from Conclusion 1 leave at least 1 acceptable value for (a).

Conclusion 4: There are infinite values (a), equal to an Integer value, which do not appear on either Surface 1 or 2.


PROOF : There are an Infinite number of Twin Primes, and their values are [2a + 1, 2a + 3] for any integer (a) not appearing on either the Surface z = 2xy + x + y or the Surface z = 2xy + x + y – 1 given integer inputs for x and y greater than or equal to 1.

You jump from examples of rows (row 1, 2, 3...) to the general case (row r). I see no proof of the general statement. Note that all examples have prime coefficient for n and q!
>>
>>9877898
All the rows follow 2r + 1, they are odd, those 3 coefficients, 3, 5, 7 are due to the 2r + 1 for the first 3 rows, not that they are prime, they just happened to be also, row 4 coefficient is 9, row 5, 11, row 6, 13, row 7, 15, and so on.

The 1st, 3 were shown just to help people see the pattern, and is clearly established by the 3, but the pattern doesn't change. This is the same as when I say for example 2n+1 for n=1,2,3..., you don't need to see the list of infinite integers if you know it increases by one each time.

You could add as many rows as you like, and the surfaces only take 2 from each row,
leaving the required amount for the row above.

so i've heard many times that vaccinations must be mandatory since, if a % of population refuses it would waste all the effort and also the reasonable ones would suffer.
this is very counter intiuitive to me: how can i be in any danger if im vaccinated? common sense tells me i shouldnt care, even if every single person in the world would get sick i still should be alright...

There's actually very little CS involved, unless you want to bootstrap your own computational chemistry program instead of using one of the ones currently available (and you probably won't.)
Start by learning QM. The first half of Simon and McQuarrie's pchem book is standard. Take special note of the kinds of approximations that have to be made to systems beyond the hydrogen atom and get a real feel for the physical rationale behind things like the self-consistent field (Hartree-Fock) and linear combination of atomic orbitals approximations. There's even a brief chapter on computational chemistry that introduces a few things. Coming in with some background in linear algebra from a theoretical, rigorous proof-based viewpoint (eg Axler or Hoffman and Kunze) helps immensely in grasping the big picture, but this is rare to see and certainly not a prerequisite.
Then you can go on to computational chemistry books like Leach, Cramer, or Bachrach, or books like Szabo and Ostlund for more theory.
Be warned, it might be more math than you're used to.
>>
>>9877612
Thanks for the reply.
How do I then get into the field itself?

>Be warned, it might be more math than you're used to.
Oh that's a good thing, I know that's my biggest weakness.
>>
>>9877623
>How do I then get into the field itself?
You do a masters/PhD in computational chemistry under a computational chemist, then get shuttled from from postdoc to postdoc because there are nowhere near enough professorships to go around and almost no industry demand for your skills.That's going to change as computing power increases and this stuff becomes more broadly useful (say, in drug discovery,) but it hasn't yet.
The other route is simply studying the material independently and using it as an adjunct to another field you specialize in, like asymmetric catalysis. It's nice to do your own geometry optimizations for your catalyst and transition states, and there's a lot of ground to break in predictive models of asymmetric catalysis. However somewhere down the road computational design of new catalysts will be possible and perhaps even standard.
Why do you want to do this? Is it because it sounds impressive/because you think it will get you a good job?
