Deepak Dhar Wins 2026 Dirac Medal for Statistical Mechanics Work
Deepak Dhar is a scientist from India who studies how many small pieces working together can create big, surprising changes.
This area of science is called statistical mechanics.
Dhar won a very famous prize called the 2026 Dirac Medal for his excellent work.
He shared the medal with three other scientists: Bernard Derrida, Marc Mezard, and Haim Sompolinsky.
The prize is given by the International Centre for Theoretical Physics, located in Italy.
Dhar is especially known for his 'sandpile model.'
Imagine adding one grain of sand at a time to a pile: it looks stable for a long time, but suddenly an avalanche happens.
This idea helps scientists understand earthquakes, traffic jams, and changes in money markets.
The Dirac Medal is one of the most famous prizes in physics, and winning it means Dhar's work has helped people all over the world.
Indian physicist Deepak Dhar has been awarded the 2026 Dirac Medal for important contributions to statistical mechanics.
The medal was announced by the Italy-based International Centre for Theoretical Physics (ICTP).
Dhar shares the honour with Bernard Derrida, Marc Mezard, and Haim Sompolinsky.
His 'sandpile model' explains how stable systems can suddenly undergo major changes, with applications from earthquakes to financial markets.
Dhar, an INSA Distinguished Professor at ICTS-TIFR in Bengaluru, has previously received the Padma Bhushan and the Boltzmann Medal.
