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

Congratulations @OilIndiaLimited ! An ocean of energy opportunities reinforced in the Andaman Sea! Very happy to report the presence of natural gas in Sri Vijayapuram-3 an exploratory well drilled by Oil India Ltd. 15 km off the east coast of the Andaman Islands at a water depth of 355 meters. Initial production testing of the well at the depth of 1900 plus meters in the Eocene formation has established the presence of natural gas through continuous flaring. Oil India is carrying out gas sampling to assess the composition & calorific value of gas and to carry out isotope studies to understand the genesis of the gas. Under the Samudra Manthan Mission (National Deep Water Exploration Mission) announced by Hon’ble PM @narendramodi Ji on Independence Day 2025, large number of deepwater & Ultra deepwater exploration wells are planned in our offshore basins to fully exploit our hydrocarbon reserves. Presence of hydrocarbon is now reported in 2(Two) wells out of 3 (Three) exploratory wells drilled by OIL in current exploratory campaign off Andaman Basin. This presence of natural gas will help us in taking forward our exploration ambitions in coordination with global deepwater exploration experts like @petrobras, @TotalEnergies, @bp_india, @Shell, @exxonmobil and will be a significant milestone in our journey through Amrit Kaal! @PMOIndia @PIB_India @PetroleumMin @mygovindia #OilIndia #EnergySecurity #Exploration #NaturalGas #Andaman

Remembering Veer Savarkar on his Jayanti. His courage and patriotism will always inspire people. His intellect and emphasis on social reform are also noteworthy.

Concluding a very productive visit to Italy. My discussions with Prime Minister Giorgia Meloni covered a wide range of sectors. A key outcome of the visit was our decision to elevate India-Italy ties to a Special Strategic Partnership, which will add new momentum to our cooperation in the years to come. I thank Prime Minister Meloni, the Government of Italy and the wonderful people of Italy for their friendship. @GiorgiaMeloni

A tribute to the courageous BJP Karyakartas! Even in the midst of celebrations at the Brigade Parade Ground in Kolkata today on the formation of the first ever BJP Government in West Bengal, we remembered all those BJP Karyakartas who laid down their lives in the service of an ideal greater than themselves. Their sacrifice is etched forever in the journey of the Party. Their courage will remain a source of strength for all of us. @BJP4Bengal

I bow to West Bengal’s Jana Shakti! The people’s blessings are the truest strength of democracy and the noblest source of public resolve.
