I taught JEE physics for years. That paper breaks strong kids in three hours.

This exam is five hours of theory and five hours of lab work, and these five did close to perfect scores on it.

Let me tell you what actually happened.

The International Physics Olympiad is the world championship of school physics. It was the 56th edition. Held in Bucaramanga, Colombia, from July 5 to 12.

381 students. More than 85 countries. Every one of them the best physics student their country could find.

India sent five kids.

All five came back with gold.

Their names are Kanishk Jain from Pune. Riddhesh Anant Bendale from Indore. Rishit Garg from Dwarka in Delhi. Shresth Suraiya from Mumbai. Svarit Joshi from Ahmedabad.

We know a hundred cricketers by their nickname and not one of these boys. :)

That clean sweep put India at joint World Number One. Tied with China, Russia, Kazakhstan, South Korea and Taiwan.

Those are countries that pour serious money and national pride into science education. We are standing level with them.

Now here is what the exam actually was.

Two papers. Each five hours long.

The theory paper had three problems. One on the thermodynamics of paramagnetic cooling. One on the photoionisation of ozone. One on the dynamics of electron positron pairs.

The experimental paper was another five hours in a lab, working through heat transfer and thermodynamic processes in fluids.

That means you get given equipment you have never seen, and you have to design your own experiment, take your own readings, handle the errors, and reach a real answer.

Not multiple choice. No shortcuts. No pattern recognition. You either understand physics or you sit there for five hours.

HBCSE says the Indian students were near perfect on theory and excellent on the practical too.

Now, this was India's 27th appearance at the IPhO.

Across all those years, about 44 percent of Indian students have won gold, 41 percent silver, 10 percent bronze.

In the last ten years, every single Indian student has come home with a medal. 62 percent gold, 38 percent silver.

Not one kid has gone and come back empty handed in a decade.

Five golds in one year has happened only twice. This year, and in 2018.

So who built this.

The programme is run by HBCSE, the Homi Bhabha Centre for Science Education. It sits under TIFR, which sits under the Department of Atomic Energy.

They run the whole funnel. A national exam, then a national olympiad, then a brutal selection and training camp, and out of everyone in the country, five kids get on a plane.

The team was led by Professor Anwesh Mazumdar of HBCSE-TIFR and Dr Leena Joshi from St Xavier's College, Mumbai.

The scientific observers were Professor Ananda Dasgupta from IISER Kolkata and Nisha Kelkar from Gogate-Joglekar College in Ratnagiri.

Yes. Ratnagiri. A college in a small coastal town in Maharashtra.

This is public education doing something the private coaching industry could never do on its own.

The coaching industry is very good at one thing. Teaching you to solve a known problem fast.

That is what JEE and NEET reward, and I say that with love because I was part of that world.

But an olympiad paper does not have a known type. There is no shortcut chapter. There is no formula sheet that saves you. You have to sit with a problem you have never seen and think.

That is a completely different muscle. And a government funded centre has been quietly building it in Indian teenagers for 27 years.

So yes, be proud. Loudly.

HBCSE also shared that around 64 percent of India's olympiad medallists go on to do a PhD.

But only about 32 percent of medallists end up settling in India.

I do not say that to spoil the moment. These kids owe the country nothing. They earned every option they have.

But it should tell us something. We are excellent at finding this talent. We are excellent at training it. We are still not great at giving it somewhere worth staying.

Congratulations Kanishk, Riddhesh, Rishit, Shresth and Svarit. This is one of the best things an Indian did this year and most of the country will never hear about it.

There is a certain type of person everywhere now, especially online.

He consumes endless information every day: philosophy, psychology, productivity, spirituality, neuroscience, business, self-improvement, history.

He knows a little about everything and deeply experiences almost nothing.

His entire identity becomes built around understanding instead of living.

He watches videos about confidence instead of speaking confidently. Reads about discipline instead of becoming disciplined. Studies relationships instead of learning how to love. Consumes motivational content instead of taking action.

He feels intelligent because he is constantly mentally stimulated. But stimulation is not transformation.

Most of the time, knowledge becomes emotional protection. Reality is unpredictable. Reality humiliates. Reality exposes weakness. Books and ideas do not.

Inside information, he can continue imagining himself as intelligent, deep, insightful, different from ordinary people. So he remains trapped in preparation.

He constantly feels as if he is "becoming" someone, while his real life remains strangely untouched. He develops sophisticated language for problems he never confronts directly. He can explain human behavior beautifully while being unable to handle ordinary discomfort, rejection, uncertainty, loneliness, or risk.

He slowly turns life into observation instead of participation.

The internet rewards this personality heavily. He receives validation for sounding aware rather than becoming capable.

Eventually, he begins confusing self-analysis with growth and information with wisdom.

But beneath the intelligence usually exists the same thing: fear. Fear of failure. Fear of embarrassment. Fear of reality answering back.

Because action destroys fantasy. The moment he truly acts, he can no longer hide inside potential.

🚀 Introducing the Qwen 3.5 Medium Model Series
Qwen3.5-Flash · Qwen3.5-35B-A3B · Qwen3.5-122B-A10B · Qwen3.5-27B

✨ More intelligence, less compute.
• Qwen3.5-35B-A3B now surpasses Qwen3-235B-A22B-2507 and Qwen3-VL-235B-A22B — a reminder that better architecture, data quality, and RL can move intelligence forward, not just bigger parameter counts.

• Qwen3.5-122B-A10B and 27B continue narrowing the gap between medium-sized and frontier models — especially in more complex agent scenarios.

• Qwen3.5-Flash is the hosted production version aligned with 35B-A3B, featuring:
– 1M context length by default
– Official built-in tools

I'm sorry but it's hard to see people lie about how legal immigration to the United Kingdom works, and say nothing about it.

I am a legal immigrant to the UK. In 2023, I had to spent roughly £5,000 for a 2.5 years visa, NHS surcharge, biometric appointment and language tests.

I will have to spend £4,000 this year, to extend my visa by another 2.5 years, after which, I'll need to pay again for indefinite leave-to-remain.

On top of that, as a legal immigrant, I am understandably required to pay taxes, national insurance and can NOT claim benefits.

This on-going myth that legal immigrants are free-loading on UK taxpayers is complete bullshit. If anything, I'm subsidising them.

My legal immigrant ass is a net benefit to your country.

[pedram.md @pdrmnvd]

you're writing a CLAUDE dot md? let me guess. "this project uses React with TypeScript."

brother claude can see the tsconfig.json. you wrote 200 lines describing your file tree to an agent that can do `ls`. you explained that ~/projects/to-do-app is a todo app.

the only lines that matter are the ones where your project is weird and you know it.

"run yarn test:unit not npm test."
"don't touch anything in src/legacy/ or three enterprise clients lose their minds."
"the auth middleware is load-bearing, yes all of it, don't be a hero."

that's it, that's the whole file. if claude would've figured it out from reading your code, you're wasting context window. start with nothing. wait for claude to do something wrong. tell claude to remember to not do that. that's your CLAUDE md.

[Iceland Cricket @icelandcricket]

Dear @ICC,

It is with a heavy heart that we now announce our unavailability to replace Pakistan in the upcoming T20 World Cup. Regardless of whether they now withdraw, the short timescales ensure it is impossible for our squad to prepare in the professional manner necessary to compete effectively in this global cricketing spectacle. We are not like Scotland and able to turn up on a whim, with no kit sponsor.

Our players are from all walks of life and cannot simply drop their occupations to fly halfway around the world to experience temperatures only normally felt in Finnish saunas. Our captain, a professional baker, needs to attend to his oven, our ship captain needs to steer his vessel, and our bankers need to go bankrupt (again). This is the harsh reality of cricket at the amateur level of the game.

This news will be extremely disappointing to our fans. Despite being the most peaceful nation on Earth, we maintain an army of online followers, and are the world's 14th most followed national board on X. We were ready to give the Dutch the biggest shock they have experienced since William of Orange lost the Battle of Landen in 1693. And the Americans were looking forward to taking on Greenland, or so their orange-dyed leader thought.

Our loss is likely Uganda's gain. We wish them well. Their kits cannot be missed unless you have epilepsy, in which case they are probably best avoided.

The future is always ice, until it isn't.

Yours sincerely,

Icelandic Cricket Association
