Come forward and show your prowess in Physics by competing with students across the country to solve problems through deliberation and critical thinking. Prepare for a battle to the end.
This is gonna be intense. This. Is. Decoherence.
This is a unique opportunity for any physics enthusiast to showcase their problem-solving ability and insight in the subject. The prelims is knocking at the door and this will serve as a gateway to the main Decoherence event!
The preliminary round is divided into two rounds - one objective and one subjective. The objective round will serve as a screening round to select teams for the subjective round. We promise that these two rounds themselves will put your abilities to test!
Unleash your skills in the Prelims to secure your way into the main event! The final event will be held in the gorgeous IISc Bangalore campus with highly subsidized tickets for your travelling and residential costs. It would be full of fun for those who love teasing their minds with new physics theoretical and experimental problems, with participants getting the opportunity to present their solutions to leading Physicists in the panel of judges!
