@divakarssathya That's right my friend, this information is free but not everyone benefits from it, so they want no one to see these lectures. So I will publish every day so that as many people as possible can see it🙏

@SwamiGa05929904 That’s a fair point. Visual intuition can make abstract concepts click much faster, especially for beginners. A good diagram can sometimes explain what a page of notation can’t

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?

@edvnagesh @Paul_Koshy I adore her, she is very smart and talented

@Rossst_03 Understanding that distribution is where real risk management begins

[Trixi @TrixiHQ]

@s01181969 Thank you very much. I will work hard on this🙏

[Trixi @TrixiHQ]

@sjgvijayakumar Great way to simplify a complex topic. The two-level model makes the core idea much easier to understand before diving into real atomic systems

@dmukkavilli Real intelligence is about making knowledge accessible and helping others grow, not keeping it behind a paywall

[Trixi @TrixiHQ]

@naam2202 She is truly an incredible and talented woman

[Trixi @TrixiHQ]

@Mike32341842 100% agree. Making high-quality education accessible to everyone is one of the best things the internet can do. Big respect to IIT Madras and NPTEL for keeping it open. 🙌

@eshpre Attendance requirements exist to protect bad teachers, not help good students

[Trixi @TrixiHQ]

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

[Trixi @TrixiHQ]

@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
