@yeungwingfung I read the textbook daily, take notes, don't move on until I understand every part it says including all examples. If I'm really stuck I write it down for my tutor to unblock. We also go over derivations together so I'm not just memorizing formulas. Then I do lots of problem sets

@lindaxie how do you actually go through the textbook each day? and how do you test / know for sure that you really get a concept before you move on?

In my 1st year physics self study, I finished mechanics, waves, and thermodynamics. I started electromagnetism and it's a big jump in difficulty. I'll get through it but def moving much slower to make sure I understand. Multiple people said it was their favorite subject though!

@deltaVee42 No worries! I know basically everyone has good intentions of trying to make me better at physics esp since I'm not actually attending a formal college program

@lindaxie Sounds good. Sorry about jumping to conclusions. Happy learning!

@lucca__pacioli Studied there today and it was beautiful! Had a whole room to myself too 😊

@lucca__pacioli Yes! Was planning on studying there tomorrow

My study location today! Biblioteca Vasconcelos in Mexico City

@csjcode I like having a solid base before moving on to more specialization personally esp since I didn't take it in college

@lindaxie I skipped all that, and went straight to wormholes, quantum gravity waves and multidimensional holographic simulation theory.

@Ludiusvox I'm really happy with my setup plus weekly tutor

@lindaxie I don't think you should self study. I think you should try going to Forsyth Tech nanotechnology, and it's very inexpensive Wake Forest Physics department, to gain more understanding of the world. You will sit in the professors library all day long gaining advanced literature.

@deltaVee42 I'm working out of a textbook and it has intro to thermo in 1st year before e&m which was not that hard just lots of equations and applying it. I know 2nd year thermo gets harder

@lindaxie ...year because it's harder than 1st-year E&M. I suppose your tutor is probably teaching you some easy thermo (like mech engineers learn) earlier than physics majors usually learn thermo since your tutor isn't sure you'll stick around long enough to learn the hard stuff. (2/2)

@deltaVee42 Yes, also my tutor and I go through derivations multiple times per week. Advanced econ used a lot of the math you mentioned (took grad classes) plus took advanced math classes and self studied in the past for quant work out of college. It just needs a ton of refresh

@lindaxie My concern is that you're learning physics from a source that's not challenging enough for you to learn what you're capable of (Grok says you majored in Economics at UCSD).

@yesjess About halfway through this and love it

@lindaxie Recommended reads?

@stringlandscape @_GrayFrog I love this one and was recommended by a lot of people! I'm not using AI, lucky I have an in person tutor that comes weekly

@lindaxie @_GrayFrog IDK if that one's any good but keep in mind that most intro books are pretty terrible. I would try several, and try to get ones as different as possible. I would also avoid any AI, they still struggle and it is impossible to tell if they're making errors when you're learning.

@_GrayFrog University physics textbook a.co/d/07u3gQgG

@lindaxie What resources are you using in your studies? I'd love to re-dive into these topics.

@deltaVee42 Learned that math you listed in college, just rusty

@lindaxie If you want to learn physics at the level of a strong university you need a lot of math, including vector calculus, ordinary differential equations, partial differential equations, Fourier series, and complex analysis. If you aren't using calculus all the time... (1/2)

@jorgejimnz_olm Thank you!! My last day, wish I had saw this earlier 😊

@lindaxie I’m a physics student from UNAM (AUTONOMOUS NATIONAL UNIVERSITY OF MEXICO) so you’re invited to visit here the “Hemeroteca” and the “Biblioteca Central”

@PeterMorganQF I'll definitely need to get further along to even understand what you're saying 😅

@lindaxie Research is very different from coursework, but at some future point perhaps consider how you would add a Poincaré invariant noise (that's how 'quantum noise' is different from thermal noise) to classical electromagnetism.

I started electromagnetism, the last section of my 1st year physics self studying. First thing that blew my mind was learning laser printers work due to forces between charged objects! e.g. positively charged toner adheres only to negatively charged areas "written" by a laser

@rodguze No I'm reading Young and Freedman but if I really like e&m I will totally check it out after!

@lindaxie please say you’re reading Griffiths, please, please. his e&m textbook is one of my favorites ever

@maubaron The food!

@lindaxie amazing, what was your favorite part about mexico city?

Tempo mainnet is live! We're also launching MPP -- a new open standard for machine payments co-authored with Stripe. It's payment rail agnostic -- works with stablecoins on any chain but also cards, Lightning network, etc.

@dwr Congrats!! 🔥

@Ladyinvisible I can see why! It's been incredible (was my first time visiting)

@lindaxie Mexico City is still probably my favorite city in the world.

@mfiguerres_ I loved it!

@lindaxie Did you like it? One of my fav spots during my Uni days.
