Some stories demand scale.

Painting Arjuna on a large canvas allows me to capture the movement, emotion and intricate details of the Mahabharata.

For me, scale is not just about size, but giving the story space to unfold.

Dear Indian origin/American leaders in the US,

@satyanadella, @sundarpichai, @ArvindKrishna, @nikesharora, @nealmohan, @MicronCEO, @JayZscaler, @kunalb11, @RamaswmySridhar, @AravSrinivas, @ThomasOrTK, @LeenaNairHR, @snarayen, @VivekGRamaswamy, @RepBera, @CongressmanRaja, @RepSuhas @Kash_Patel

It is high time you all speak up against the despicable, dangerous racism and hate against Indians on American social media. And do something about it as Tech CEOs and political leaders.

The despicable, dehumanizing hate against Indians is being spread everywhere - Facebook, Instagram, X, Youtube, Reddit, Telegram...

Staying silent and not doing anything anymore - as more young people in the US are radicalized to hate Indians using social media - may one day lead to our own family and friends having to face such racist, radicalized, violent, supremacists.

American social media platforms are being used by adversarial actors to specifically target Indians in the US.

They are seeding racism and hate using violent words and dehumanizing imagery, programming many Americans to become racist and hateful - specifically against Indians.

May be it is being done to drive out Indians, attack India for geopolitics, or try erode India-US ties. But it is real, relentless and extreme form of communist hate that's being seeded.

There's no reason why, you all as stalwarts of silicon valley and politics can't get together, talk about this crisis, and take action to end ALL hate and racism on social media.

It shouldn't be that difficult in the age of AI to filter out, block racist and hate filled comments against any community, isn't it.

How come this is not being proposed and implemented across SV companies? And why isn't any of you speaking out against this increasing online hate and racism against Indian Americans and Indians?

Among all mentioned above, till now only @CongressmanRaja has talked about the topic of online hate and the recent attempted mass shooting.

Please start talking among yourselves, even if not publicly, and kindly take some action 🙏

The oldest map we may ever have had is a 14-metre elephant carved into the ground near Ratnagiri. c. 12,000 BCE.

It has no fence, no signage, no monitoring. Yet my analysis of it is the lead article in a London map journal this month.

My analysis arguing it is a map of the subcontinent's known world, older than Çatalhöyük by six millennia, is the lead article in the IMCoS Map Journal, No. 186, Sept 2026.

The International Map Collectors' Society put it on page 4.

The Ancient Monuments Act of 1958 has no category for it. A carving that is the ground itself cannot be fenced, ticketed, or given an asset value. So the central inventory never recorded it.

Inside the outline there are six species, each placed where it actually lived: tiger in the east, langur in the Himalayan north, rhino on the Ganga-Yamuna doab, pangolin in the south.

The width-to-height ratio of 1.167 matches the walkable world at 12,000 BCE, when the Sunda Shelf was dry.

It is a hypothesis. It needs direct dating and a proper statistical test, and I say so in print.

But a hypothesis about 14,000 years of human geography is being argued over in London, while at home the monsoon erodes the incisions every year, with no 3D record of them.

We paid to protect the monuments that sell tickets.

The oldest map we may ever have had sells none.

Who is documenting it before the next monsoon?

What happens when a phenomenon usually associated with unconventional superconductors turns up in a material from a class long considered conventional?

A study led by Prof. Ravi Prakash Singh and his group at IISER Bhopal, in collaboration with researchers from the Indian Institute of Technology Kanpur (IITK), and the ISIS Neutron and Muon Source, has reported evidence of time-reversal symmetry breaking in the type-I superconductor YbSb₂.

Superconductors carry electric current without resistance below a certain temperature. Type-I superconductors are generally considered the simpler class, while unconventional behaviour is usually associated with type-II materials.

The team found that spontaneous internal magnetic fields appear when YbSb₂ becomes superconducting. This is direct evidence that the material breaks time-reversal symmetry, a hallmark of unconventional pairing. The finding offers a new platform for exploring the connection between superconductivity, magnetism, and topology.

The work is published in Physical Review Letters as an Editors' Suggestion. It has also been featured as a Synopsis in Physics Magazine of the American Physical Society.

In 2012, a 19-year-old aeronautical engineering student from Coimbatore presented propulsion research at a NASA event. Dr. APJ Abdul Kalam noticed, sought him out for a meeting, and handed him a recommendation letter with one challenge: prove your concept.

That student was Rohan M. Ganapathy. Three years later, he and family friend Yashas Karanam co-founded Bellatrix Aerospace from IISc's incubation lab in Bengaluru. The problem they chose to solve touches every satellite in orbit.

Nearly all satellites run on hydrazine, a propellant that has been standard since the 1960s. It is deeply toxic, carcinogenic, and so hazardous that it requires specialized crews and loading facilities near the launch site. India imports all of it. Nobody was building an alternative.

Bellatrix built two. Rudra is India's first high-performance green propulsion system, delivering hydrazine-equivalent thrust while cutting handling costs by over 60%.

Jal is a microwave plasma thruster that uses water as propellant, which Bellatrix claims is the world's first such system built by a private company. Both have been tested in orbit: Rudra fired on ISRO's POEM-3 in January 2024, and again on POEM-4 in January 2025.

Their third product, Pushpak, is an orbital transfer vehicle the company says can bring satellite deployment costs from $45,000 to $25,000 per kilogram. In October 2024, Bellatrix signed an MoU with ISRO's commercial arm, NewSpace India Limited, to integrate Pushpak into its launch missions. The company has raised $31 million to date, backed by BASF Venture Capital, Inflexor Ventures, and Cactus Partners.

For India, a domestic green propulsion stack means less dependence on imported hydrazine, lower costs for Indian satellite startups, and export-ready technology in a global market actively moving away from toxic fuels.

Kalam asked Rohan to prove his concept. More than a decade later, the proof has been fired in orbit.

Hindu men should proactively work to become more masculine. You are losing it over screen based visual entertainment and social media.

Three concrete recommendations

1. Make Hanuman your role model. Study his life in detail as per Ramayan. Always think what Hanuman ji would do. And emulate.

2. Stop all forms of visual stimulations. Instead of movies, read books. Do dhyana for at least 15 minutes.

3. Keep Geeta Chapter 2 - word by word - handy. Keep reading again and again. Follow to last detail.

These are bare minimum. Flout any of these and you will be a lesser man than what you could could be.

We need real solid men to save our civilization and spread it as epicenter of world.

Else, we wither away.

Humbled to share that we successfully test fired 4 semi-cryogenic rocket engines simultaneously, as a cluster.

All the 4 engines are 3d printed as single pieces of hardware - designed and manufactured in-house at AgniKul Cosmos Rocket Factory - 1. As with all our propulsion systems, these 4 engines are also powered by electric motor driven pumps.

This test involved calibrating 8 pumps, 8 motors and tuning 8 speed control algorithms to work together in perfect sync to achieve uniform startup, steady state and shutdown performance across the entire system. As with the last cluster test, to the best of our knowledge, this is the first time such a test has been performed in India with semi cryogenic engines.

We are extremely grateful to have the opportunity to be building world class, original space technology from India, for the world with the support of @iitmadras @isro and @INSPACeIND

From here on, the addition of engines to our clusters will likely increase non-linearly. #Agnibaan #RocketEngineCluster #ElectricPumpFedEngines #Agnilet #SinglePieceEngine #3dprinting #RocketEngineTest #AdditiveManufacturing #Agnikul #AgnikulCosmos #StartupIndia #MakeinIndia #madeinIndiaForTheWorld
