@K30318Kashyap I need to search. I will definitely post the most interesting ones.

IIT Madras professor S. Lakshmi Bala walks a full quantum mechanics class through the two-level atom, and she does it for free.

Western physics departments charge over $2,000 per credit for a graduate course in quantum mechanics. This entire course has been free since the early 2000s, but someone is trying to hide it.

In this lecture she has already moved past abstract vector spaces into a real physical system, the same two-level atom model that shows up later in laser physics and quantum computing.

No login wall. No certificate fee to just watch. One professor, one blackboard, one camera that never stopped rolling for over 40 lectures.

Physics departments built million dollar tuition systems around gatekeeping exactly this material. IIT Madras just recorded it and gave it away through NPTEL, a program that now hosts over 3,200 free courses.

▪ $0 to watch, no account required
▪ Filmed lecture hall style since the early 2000s
▪ Same physics that underlies quantum computing today

🔖Just don't lose it and find a way to save the lecture, because other paid institutions don't want you to have access to it for free.

An IIT Madras physics professor teaches a full graduate level quantum mechanics course for free, and almost nobody outside India has heard of it.

It's part of something called NPTEL, a government backed program that now hosts over 3,200 free university courses taught by professors at IIT and IISc, India's top engineering and science schools.

Dr. S. Lakshmi Bala's course, Quantum Mechanics I, runs through the same material a physics graduate student would sit through in a paid semester: postulates of quantum mechanics, angular momentum, quantum optics, all of it filmed lecture hall style and uploaded for anyone to watch.

No login wall, no certificate fee required to just watch, no tuition. Just a professor, a blackboard, and a camera that's been running since the early 2000s.

Western universities charge thousands per credit for exactly this kind of course. India just recorded it and gave it away.

Is this the biggest free education archive nobody talks about, or are people just not looking?

@0xFinrex Yes, that's right. A very smart woman))

[Trixi @TrixiHQ]

@Vaibhav07807470 Many people like her handwriting, it's true, it's very beautiful😍

[Trixi @TrixiHQ]

@MavericK1TG I completely agree with you, I adore her))

[Trixi @TrixiHQ]

@shashank_b90 Yes, his way of making quantum mechanics intuitive is hard to beat.

[Trixi @TrixiHQ]

@HJ91 I really like her handwriting too🫶

[Trixi @TrixiHQ]

@Solerbtc The fact that Strang’s lectures are freely available is honestly one of the best educational deals on the internet

[Trixi @TrixiHQ]

@bubosees You can have Nobel Prizes, experience, and brilliant models - and still lose everything if the downside is bigger than you can survive

[Trixi @TrixiHQ]

@Mavernxbt Wow, that's interesting. Good job, buddy. I like it. And the girl is real

[Trixi @TrixiHQ]

@Mavernxbt The real advantage is having the discipline to actually learn, apply it, and keep going when most people scroll past

[Trixi @TrixiHQ]

@bubosees I’d start with a beginner-friendly intro to quantum mechanics, then build up the math gradually. Don’t jump straight into the heavy stuff - getting the intuition first makes everything click much faster

[Trixi @TrixiHQ]

@YourAlphaMom The information is everywhere now. The real advantage is knowing what’s worth learning and actually taking the time to go deep

[Trixi @TrixiHQ]

The key point is that Rutherford’s experiment used a "macroscopic gold foil", not a 100 nm nanofilm. The scattering pattern was statistical: the rare large-angle deflections were far too frequent to be explained by grain boundaries or dislocations. They were best explained by a tiny, positively charged nucleus concentrated at the center of each atom. So no, those possibilities don’t invalidate the nuclear model.

@mayuresh1704 Open education isn’t new at all. MIT, Stanford, Harvard and others have been putting full lectures online for years. The real shift is making that knowledge easier to discover, personalize, and learn from at scale

[Trixi @TrixiHQ]

@ZentrixHQ he understood the direction technology was heading decades before everyone else

[Trixi @TrixiHQ]

@Di_Krass_ That’s a wild way to look at trading. If the path itself has no slope, a lot of what traders call “trend” might just be noise with a story attached to it

[Trixi @TrixiHQ]

@ujjwalhoon I saved it on my computer a long time ago, I don't remember where I found it. But I have more lectures that I will publish, so stay tuned

[Trixi @TrixiHQ]

@Rams_Revenge Definitely. But everything new is well forgotten old

[Trixi @TrixiHQ]

@parisrohan26 Depends how comfortable you are with calculus and linear algebra first. If those are solid, why not start and see how far the first few lectures take you
