A bit late in RTing, but tomorrow's @chaiandwhy session will be a treat. Prof. Vijay was Michel Devoret's PhD student & has papers with both other Nobel Laureates. Can't hope for a better insider view of the Physics Nobel Prize for 2025! @PrithviTheatre & on YTLive. #scicomm
On Sunday, Dec. 7, 2025, Dr. R. Vijayraghavan, TIFR will discuss the year's Nobel Prize in Physics. He has worked with all the three laureates and the session is going to be very exciting! https://t.co/wZquaPLsbx YT link: https://t.co/eOfnICyDob

The world isn't exact & approximations are more useful to deal with the real world. Piyush Srivastava will takes us on a historical journey of how approximations have helped understand the world. In person @PrithviTheatre & on YT Live (no chai!) https://t.co/xBv6Lo0RUw
#scicomm
Ever wondered why and how approximate could be "good" when "exact" is hard to find? What is the theory and practice of mathematical approximation? At 'Chai and Why?' on Oct. 5, Prof. Piyush Srivasatava will discuss these and more. Welcome! @TIFRScience @TifrArnab @SciComm

This should be very cool!! The @TIFRScience Low Temperature Facility, ably led by Dr. K.V. Srinivasan not only produces cryogens like Liquid He & Liquid N2 supporting our research, but has also designed and developed several critical components for cryocoolers.
To mark Engineers Day, Dr. K V Srinivasan shall discuss "cryocoolers, their scalability, engineering and importance in low-temperature research". 11 AM, Sept. 21 at DG Ruparel College, Mumbai

What better than a Chai and Why? session on Olympiads while the @ioaa_2025 is happening in town? A session by the President of the IOAA @aniket_sule himself! Do join in, it is a lot easier than the Olympiad itself😊 #scicomm
International Olympiad on Astronomy and Astrophysics is currently ON in Mumbai. Prof Aniket Sule will tell us about what exactly is and what happens at an Olympiad? Who participates and Indian Involvement in Olympiad so far. #IOAA2025 #scicomm #astronomy

isn't it amazing when an OTT star stops by the centre wanting to help us spread the news on #IOAA2025?! Had a wonderful time engaging with @amolparashar during his visit to the centre!
We are in full galaxy mode 🌌 @amolparashar + HBCSE brought quite the buzz for the launch of #IOAA2025, the biggest IOAA to date! 🚀 Tomorrow is the first theory exam. Let the star power shine — sky waale and future waale 🌟 #AstronomyOlympiad #CosmicCollab #MumbaiEvents

Totally over the moon for these brollies… amazing logo placement! We're all set for #IOAA2025
T-1 day to #IOAA2025! 🌧️ If you’re organizing an Olympiad in monsoon-soaked Mumbai, an umbrella is a must. But for an Astronomy Olympiad, it's gotta be celestial!☂️ Check out what our registration team came up with. In a phased manner of course. Would you rock this? Let us know!

Behind every international Olympiad: a print zone busier than a copy shop! Once questions are set and translated, our IOAA team races thru the night to print, seal, and deliver the right exam papers to every student, on time—precision under pressure! #IOAA2025 #BehindTheScenes
T-2 days to IOAA. Boxes of paper are ready. Soon the jury will debate all day, leaders will translate all night—and by morning, our team will have exam papers printed and on every student’s desk! With crunch‑time coordination, caffeine, and commitment! #IOAA2025 #BehindTheScenes

The brainpower at IOAA is truly next-level! High school students dive into questions that would make many PhD students break a sweat. The science olympiads aren’t just tough—they showcase phenomenal young talent & scientific curiosity. #IOAA2025, coming to Mumbai next week!
Think IOAA questions are easy? T12.1, IOAA2016 asked: AstroSat’s LAXPC detects X-rays from supernovae What minimum velocity shifts an X-ray line into a different detector channel? Our young stars calculate cosmic Doppler shifts—precision instrumentation,real data,real challenges!

T-5 days and counting.... The sheer backend work needed to prepare for an international olympiad. Just guess how many things need to into every backpack that the visiting student will get! All meticulously packed and made ready.
Behind the scenes! 🎥💫 A glimpse into the hard work and dedication that goes into preparing for the 18th IOAA 2025 in Mumbai. ✨ #behindthescences #hbcsetifr #ioaa2025 #astronomy #astrophysics

Congrats @KKNManeesha!! I learnt so much about β-Ga₂O₃ (& good mallu food😊) thanks to you. As the S&G song goes ... Sail on, silver girl Sail on by Your time has come to shine All your dreams are on their way ... Dream big and fly high!
Congratulations to Dr. Maneesha Narayanan for a successful #PhDdefense at the Dept. of Condensed Matter Physics & Materials Sciences, @TIFRScience! Working with Prof. Arnab Bhattacharya, she explored the hidden powers of β-Ga₂O₃—an unsung hero among wide-bandgap semiconductors.
