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.

Let me school you—gently
To begin with, “Onam” is the shortened name. It is Thiruvonam—the sacred nakshatra associated with Bhagavān Vishnu.
Kerala’s cherished tradition connects Thiruvonam with Mahābali. And where is Mahābali’s story found?
• Śrīmad Bhāgavata Purāṇa — Skandha 8
• Vāmana Purāṇa
• Matsya Purāṇa
• Kūrma Purāṇa
• Nārada Purāṇa
• Skanda Purāṇa
• Padma Purāṇa
• Brahma Purāṇa
None of these texts says that Mahābali returns specifically to Kerala. But that is perfectly fine—traditions grow around sacred memory, and Kerala’s tradition deserves to be cherished.
What is not fine is pretending that Thiruvonam has nothing to do with Hinduism.
Its name is Hindu.
Its nakshatra is Vishnu’s.
Its central figures come from Hindu scripture.
Its cultural memory is unmistakably Hindu.

Another big action by @Tukaram_IndIAS Sir.
I just love the way you are working. Nothing nonsense, follow the rules or get your license suspended.
These are not some small roadside restaurants. These places charge premium prices and fool people in the name of food safety.
1) McDonald’s Colaba - License suspended
- Failed in 18 out of 20 safety points
- Using cheese analogues without declarations
- Live cockroach infestation found
- Handling ready-to-eat food without washing hands after handling dirty footwear and soiled cleaning cloths
2) The Bombay Presidency Radio Club - License suspended
- Safety and hygiene violations
- Fly infestations in kitchen areas
- Dead cockroach found in the washing area
- Flaking ceiling plaster directly over food preparation areas
3) Khar Gymkhana - Food registration certificate suspended
- Storage arrangement issues
- Poor cleanliness
- Hygiene lapses and critical food safety violations
- Improper thawing of frozen food
4) Novaara Restaurant - License suspended
- Warned on August 13 for improvement
- Still no satisfactory improvement in 14 out of 25 serious deficiencies
- No cockroach traps in the drainage line
5) Status Restaurant - License suspended
- Employee washing his face directly over clean food utensils and found working without protective equipment
It takes courage to suspend such big brands. Coward officers can't do it.
Just one officer has shaken up the whole of Maharashtra. Just imagine if he becomes the CEO of @fssaiindia. Pura desh safe ho jayega.
