Event description

The Ri building may be closed, but our work continues online. Register below to receive a link to the livestream.

Physics is a crucially important science that tells us about the Universe and the nature of reality itself.

Join Jim Al-Khalili as he explores the fundamental concepts of space, time, energy, and matter, and describes the three pillars of modern physics, quantum theory, relativity, and thermodynamics.


During this time your donations are extremely important to the Ri.

By donating £5 to the Ri your support enables us to continue our vision to inspire everyone to think more deeply about science and its place in our lives. You can make your donation go even further by agreeing to Gift Aid it. Every £1 you donate could be worth £1.25 to the Royal Institution at no extra cost to you.

Every donation makes a difference and we are extremely grateful to all of our supporters.

About the speaker

Jim Al-Khalili has presented The Life Scientific on Radio 4 since 2011. Although his ‘day job’ is as an academic professor of physics at the University of Surrey, where he also has a chair in the public engagement in science, he has achieved wider prominence as a public scientist, author and broadcaster. He has fronted a number of radio and television documentaries, mainly on BBC4, including Chemistry: A Volatile History, which was nominated for a BAFTA in 2010.
