Math I'm Using For My Theoretical Physics Internship

Lets talk about math. Theory requires lots and lots of math. In this video I go over one specific aspect of my internship, namely the Hadronic Tensor. I place specific terms of the tensor into different categories of math to give a rough idea of what you should learn if you want to pursue theoretical physics. More specifically, theoretical nuclear/particle physics.

You lost me at, "what's going on smart people?"

[Excidium]

Those equations are the universe nude. lmao.

Answer to your last question: I think it looks cool, most people seem to be repulsed by hard looking math, but I think it’s pretty, and it makes me want to learn it

[lilcrowlet]

Honestly, it looks both terrifying and wildly amazing. Maths tends to become less scary the more you understand what it means.

For me, I've definitely always had an affection for mathematical symbols (tbh. symbols in general, eg. exotic writing systems like that of the Georgian language, musical notation etc.). Though with maths it's always been the strongest. I can clearly remember looking at the chalkboard with stuff still written on it from prior calc classes when I was in middle school and feeling this urge to not only understand these symbols but also to be able to use them properly. Looking back at that, I still get a deep satisfaction from looking at mathematical formulas and understanding not only the symbols in them, but being able to imagine what they represent outside of their algebraic notation. Maths is like a language which has no words, only grammar, but once you've internalize these grammatical rules, you can imagine a story unfold without ever needing to use words.

I think it looks really cool AND terrifying.

You should do a series on Lagrangian and Hamiltonian mechanics after the tensor stuff.

I think what this video shows is how deep the subject is. There just loads of concepts you must grasp and grasp well. It's a reminder that you need to master each subject in turn. For those of you going to uni soon, you're going to be tempted to skimp on things at times due to time constraints... you don't dictate the pace of learning, and that can be a massive challenge. Don't fall into the trap of "getting through it" at the expense of really learning the material. It will catch up to you at some point.

[zokalyx]

I get scared but I'll fight it, not run. I always want to learn more (It feels dope to know, at least for me)

I remember when I saw integral signs far off in the distance and I was like:
dafuq is that symbol it must be quantum string theory of dark matter

I'm finishing my sophomore year for a bachelor's in electrical engineering. I do really enjoy designing circuits and dealing with processors and low-level protocols but seeing math like that makes me want to pursue a mathematics or physics degree. I'm taking E&M right now and thoroughly enojiying it. Last semester I took linear algebra and found it to be my favorite math course yet because of its abstractness compared to the calculus trilogy (quartet if you count diff.eq). Now I'm taking "Introduction to Mathematics" so that next semester I can take some 4000 level abstract math courses just for the sake of doing more math. Anyone else in a similar situation?

[ClanNamedHipNotic]

Im only at the ending of Calculus 2 and I haven’t took Physics yet, but omg this video is just raising my curiosity!

[brianhernandez]

I’ve always been inclined towards math, and this year as a high school junior I took an electricity and magnetism class at a local college. But even then, as long as I can remember, I’ve always had the thought in my mind that I’m going to be in the medical field working as a doctor. Your channel is really making me reconsider this thought, and I’m now seriously considering double majoring in math+physics and head to grad school for physics; I’d like to thank you for it. Keep up the good content!

[dorol]

It makes me excited, because I knew like 80% of those terms, however I don't know how to compute them (the highest math I know atm is Linear Algebra up to Eigenvalues and Determinants and the differential side of Multivariable Calculus). It's very cool that you can combine so many of these things

[GiI]

One of the best pieces of advice I learned was to write down new equations as you encounter them. You understand so much from doing that!

[tommchunu]

Andrew makes my aspirations of being a theoretical physicist seem to be in reach :) You're doing a great job man, keep the good energy flowing

[illuminatedrd]

That equations looks super cool! thanks for uploading man you're super awesome for doing this : )

[thephysicist]

Cool but I didn't understand anything

[lerubikscubetherubikscube]

2:00 Yeah, that's definitely a thing. I think the exciting part about spending energy to understand equations from a textbook is that in the end you'll get a meaningful interpretation/result. Also, this makes me appreciate the effort (with no guarantee of results!) required to derive a model that represents reality.

[bartubmaiden]

Hey Andrew, I just finished my sophomore year today and feeling pretty good about it! I started following you about 3 months ago, and it was very interesting to stumble upon your channel because I had a similar pass-time activity idea of my own to start a youtube channel about all the beauty of physics and maths, and not in a half-ass babbling way, but not too rigorous either; your content, in my opinion, is right on top of that sweet spot for people that might be interested about all of this, and I wanted to thank you for the videos and what not! Keep the good content up (as much as you can allocate time!)

[BigFatSandwitch]

For me it looks really cool. The fact that something as abstract as that equation has a meaning to it is just beautiful
