🇮🇳 Outstanding feat by Team India at the 67 International Mathematical Olympiad (#IMO2026) in Shanghai, China! Competing in the largest-ever IMO with 666 students from 117 countries, India secured 2 Gold and 4 Silver medals, achieving an (unofficial) global rank of 7th. 1/5

[HBCSE @HBCSE_TIFR]

Another Golden Sweep by India as our Chemistry team bags 4 Gold medals securing Rank #1 (jointly with China, Vietnam, and Individual Participant (Russia)) at the 58th International Chemistry Olympiad, Uzbekistan (https://t.co/ZCxapjbtvG).
1/5

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.

🇮🇳 India Tops the World at the 56th International Physics Olympiad 2026!

🥇🥇🥇🥇🥇India's young physicists deliver an extraordinary performance at #IPhO2026 in Colombia. All five members of the Indian team win Gold Medals. 1/3

@quartzdevgg @charliedeets I recently gave Dia a try for a few weeks. While it comes close to Arc, it still feels like a second copy of Arc for the same reasons you mentioned. Sidebar UI is still not as good as Arc. So I ended up switching back to Arc again.

[Chintan R. Dave @crdave1988]

@charliedeets @quartzdevgg Tried Dia for 3 weeks and still went back to Arc. Aside from the AI features, Dia just feels like a knockoff.

Arc still wins on sidebar UI + Spaces, PiP, Air Traffic, and simple things like pinning a URL without forcing it into a group.

[Chintan R. Dave @crdave1988]

@diabrowser Is syncing profiles between Macs on your roadmap?

[Chintan R. Dave @crdave1988]

@diabrowser Can I do sidebar stuff (Profile, Switching, etc.) like Arc?

[Chintan R. Dave @crdave1988]

@joshm @diabrowser Still using arc because vertical tab with better space and profile switching. I was waiting for it to be available in dia but now it seems like they are not interested.

[Chintan R. Dave @crdave1988]

@Ravisutanjani Per transaction 5 and total per day 10?

[Chintan R. Dave @crdave1988]

@immasiddx I was OK with the call app but they have ruined the clock beyond any doubt.

[Chintan R. Dave @crdave1988]

@aaraynsh Is it New Delhi platform 1?

[Chintan R. Dave @crdave1988]

@diabrowser Yes, if it has improved sidebar like Arc.

[Chintan R. Dave @crdave1988]

@BrahmaSai77

[Chintan R. Dave @crdave1988]

@adamstern_ @diabrowser Now I can give it a try 👍.
I play it quick and I like the initial impression as a first release. The first thing I miss is a shortcut to change profile and profiles as icons instead of dropdown for quick access. BTW does dia has Air Traffic Control?

[Chintan R. Dave @crdave1988]

@adamstern_ @charliedeets @diabrowser Yes, the lack of a sidebar is a significant barrier preventing me (and I believe many other loyal Arc users) from switching to Dia.

[Chintan R. Dave @crdave1988]

@BlaShadow @ios_memes Actually, I am still there..😅

[Chintan R. Dave @crdave1988]

@hasmukhpatel @narottamsahoo It was just light moving in a direction. So visually not very interesting.
