Chandrasekhar died exactly 31 years ago today. At 19, on the boat from India to Cambridge in 1930, he worked out that a white dwarf above ~1.4 solar masses could not remain stable. Eddington publicly rejected the result. 53 years later, Chandrasekhar won the Nobel Prize for his work on stellar evolution.

@DMadathil8 @san_x_m Yes, the independent lithium-ion battery design from Shaivee Malik, Vivek Mahindrakar and Dharmik Bapodara delivers clear cost and uptime gains over diesel-tied reefers for intra-city runs.

[Dev M @DMadathil8]

@san_x_m Good job Shaivee Malik and team.

Yotuh's unit is fully electric and runs solely on its own lithium-ion battery, completely independent of the truck engine or any diesel. It works even when the vehicle is off or broken down, needs no fuel for cooling, and fits small commercial vehicles for intra-city use.

Traditional Thermo King reefers are usually either engine-driven (compressor belt from the truck engine, so it idles and burns diesel while stopped) or self-powered with a separate diesel engine. Containers typically use electric units plus diesel gensets for road moves. Yotuh cuts running costs ~75% via electricity instead of diesel, with zero local reefer emissions, though runtime is battery-limited (typically 6-16 hours).

At 7 he built a website and ended up in the Guinness records as the world's youngest male webmaster.

At 16 he built a satellite in a school in Jammu.

At 19 he raised 4.3 million dollars in Silicon Valley to fix a problem that even NASA has never fully solved.

His name is Onkar Singh Batra.

He was born in Jammu. His father works in information technology, and that is where his interest started.

He wrote a book at 12. He started a company at 13. He received the National Bal Shakti Award from the President of India for building an interactive website during the pandemic.

In 2020, at 14, he became interested in space.

In 2022, while he was in class 12 at a school in Jammu, he built a satellite called InQube. It weighed about 1 kg. It was India's first open source satellite, which means the design was published for anyone to use.

In the same period he was invited to teach space systems to engineering students at IIT Jammu as a guest professor. He had not finished school.

While building InQube, he ran into a problem that runs through the whole space industry.

Satellites in low Earth orbit go dark. For long stretches of every orbit they are not in line of sight of any ground station on Earth, so nobody can talk to them. These are called dead zones.

It sounds small. It is not. A satellite watching a flood or a fire can be holding the picture you need and be unable to send it for the next 40 minutes.

The existing fixes are partial. You can build more ground stations, which is slow and expensive. You can use relay satellites, but most of them need the customer satellite to carry particular hardware, which most older satellites do not have.

In 2024 he founded a company to solve it. It is called Apolink, from apogee and link. It is based in Palo Alto in California.

The plan is a ring of 32 small satellites carrying both lasers and radios, acting as ground stations in space, and working with satellites that were never built for it.

In 2025, at 19, Y Combinator and other investors put 4.3 million dollars into it, at a valuation of 45 million dollars.

In July 2026 the company launched its first demonstration satellite on a SpaceX mission.

He is 20 now.

He wrote about himself on his own website in plain language. Built websites at a somewhat prodigious age. Got awarded by the President of India. Built a satellite at 16. Brought myself to the United States.

A boy from Jammu is building the internet for space, and almost nobody in his own country knows his name.

@san_x_m @grok - please verify the claims in this post and the approval received by FDA.

@nabilajamal_ Alas! The jewelers started scamming the governments too. @grok - can this be a scam or vote harvesting process?

On 27th November 1981, a scientist at IBM brought his leftover Thanksgiving turkey to the laboratory and shot it with a laser.

More than 40 million people can see without glasses because of what happened next.

His name is Rangaswamy Srinivasan.

He was born on 28th February 1929 in Madras. He took his bachelor's and master's degrees in science from the University of Madras in 1949 and 1950.

In 1953 he went to America for graduate school, and finished a doctorate in physical chemistry at the University of Southern California in 1956. In 1961 he joined the IBM research centre at Yorktown Heights in New York, where he stayed for 30 years.

His work was on what ultraviolet light does to organic matter.

In 1981, using a new kind of laser called an excimer laser, he found he could etch fine designs into plastics.

Then he and 2 colleagues, James Wynne and Samuel Blum, asked a question. Human tissue has some properties in common with plastic. Could the same laser cut flesh.

At the time, lasers were already used in surgery. The problem was that they worked by burning. They left heat damage and scarring on everything around the cut.

They needed something to test on. The day after Thanksgiving, Srinivasan brought in cartilage from his family's turkey leg.

They fired the laser at it.

The cut was clean. Microscopically fine. No burning, no charring, no damage to the tissue underneath.

He named the effect ablative photodecomposition. The laser was not burning the tissue. It was breaking the molecular bonds and lifting off one thin layer at a time.

In 1983 an eye surgeon named Stephen Trokel came to the IBM laboratory to work with him on whether this could be used on the cornea.

It could.

That is the foundation of PRK and LASIK, the surgery that reshapes the front of the eye and removes the need for glasses.

More than 40 million people around the world have now had it.

He published over 130 scientific papers and holds at least 22 American patents. He was inducted into the United States National Inventors Hall of Fame in 2002. In 2013 President Barack Obama gave him the National Medal of Technology and Innovation.

He is 97 years old.

A man from Madras worked out how to cut a human eye without burning it, using a piece of turkey left over from a holiday he did not grow up with.

[Grok @grok]

Verified: The post is accurate on his background, the 1981 turkey cartilage experiment with Wynne and Blum that discovered ablative photodecomposition, the 1983 work with Trokel enabling PRK/LASIK (now used by 40+ million), 130+ papers, 22 patents, 2002 Inventors Hall of Fame induction, and 2013 National Medal from Obama.

Additional achievements: Elected to National Academy of Engineering (1999); Max Delbruck Prize (APS, 1998); R.W. Wood Prize (OSA, 2004); Prize for Industrial Applications of Physics (AIP, 2004); Fritz J. and Dolores H. Russ Prize (NAE, 2013); ACS Award for Creative Invention (1997); visiting professorships at CUNY, Columbia, and Harvard; founded UVTech Associates. APD also applied in chip packaging and inkjet printers.

@san_x_m @grok - please verify and give any additional achievements of R Srinivasan missing here.

[Dev M @DMadathil8]

@ZardSi @grok - what is he talking about? Please fact check.

[Dev M @DMadathil8]

@grok @Islam435 Thanks @grok - according to original post these craps are not prohibited. So seems like permissible.

@ARahMoh We need to show respect to them and get back respect from them.
The narratives are peddled up against the Indians.
We can break it and move along

Americans hate H1B Indians as they think they are scammers
TikTok has convinced Americans that every scammer is Indian

The FBI data says that it's wrong

Americans lost $20.9 BILLION to fraud in 2025.

$12.5 BILLION 60% came from scam compounds in Myanmar, Cambodia & Laos run by CHINESE crime syndicates.

The Indian call center category? Under 9%

You’ve been hating the wrong people over the smallest slice of the pie.

Why the stereotype? Simple:

Call centers use VOICES. Voices become viral scam baiting videos.

Pig-butchering compounds steal 8x more through TEXT no accent, no face, no content. So they stay invisible while racking up billions.

The algorithm made the loudest scam the face of ALL scams.

Meanwhile: India’s CBI + FBI = 475+ arrests in 27 joint operations. Operation Chakra just crushed a Noida network.

Name another country doing that.

And Indian Americans? Zero connection to any of it. Hating your neighbor for a criminal 12,000 km away is not good IQ

Stop letting TikTok think for you. The FBI report is free.

@itxbeenishhere @grok - why these PK clowns are after Kerala India muslim girls? Is it for ‘X’ monetizing or harvesting likes, shares and followers? These are really pests.
