About Oskar Klein Medal:

• It is a prestigious international award that recognises outstanding contributions to theoretical physics.
• Established in 1988, the medal honours the legacy of Swedish theoretical physicist Oskar Klein.
• The medal is awarded annually by Stockholm University and the Nobel Committee for Physics of the Royal Swedish Academy of Sciences.
• Past recipients of the medal have included some of the world’s top physicists, Alan Guth and Stephen Hawking, and Nobel laureates Peter Higgs, Kip Thorne, and Steven Weinberg, among others.

2026 Winner:

• Professor Ashoke Sen, a renowned Indian theoretical physicist, was awarded the Oskar Klein Medal 2026.
• He is the first Indian to receive the award.
• The award recognizes his pioneering contributions to string theory, which seeks to explain the fundamental nature of the universe, black hole entropy, and string field theory, which have significantly shaped modern theoretical physics.

What is String Theory?

• String theory is a scientific framework that attempts to explain how the universe works at its most fundamental level.
• According to this theory, the smallest building blocks of matter are not point-like particles but tiny, one-dimensional objects called strings.
• These strings can vibrate in different ways, with each pattern of vibration corresponding to a different particle.
• In this way, string theory offers a possible common framework for understanding the different particles and forces found in nature.
• One of its major goals is to bring gravity into the framework of quantum physics, which describes the behaviour of matter and energy at extremely small scales.
• Scientists have long struggled to reconcile the two, particularly in extreme environments such as black holes, where gravity and quantum effects become important.
