Scientists have always used models. From the ancient Ptolemaic model of the universe to the astrolabes of the Renaissance, models have mapped the consequences of predictions. They allow scientists to indirectly explore worlds to which they would never have access.

Join Sir Richard Catlow to explore how high-performance computer simulations have transformed the way scientists understand our world. From testing hypotheses on a global scale to developing a personalized approach to fight Covid.

This Speech was recorded at Ri on May 27, 2022.

The Lectures are one of Ri's oldest and most prestigious lecture series. Since 1825, theater audiences have witnessed countless moments of thought, including the first public liquefaction of air by James Dewar, the announcement of the electron by JJ Thomson, and more than 100 lectures by Michael Faraday. More recently, we have had Nobel Prize winners, Fields Medal winners, scientists, authors and artists – all from the forefront of their fields. The speeches are an opportunity for the best and brightest to share their work with the world.

Sir Richard Catlow was educated at Clitheroe Grammar School and the University of Oxford and spent his career as a scientist working in interdisciplinary areas relating to the development of functional materials for energy and catalytic technologies.

Richard was one of the pioneers in the development and application of computational tools in chemistry and materials science. He has published numerous articles and his work has been recognized by election to the Fellowship of the Royal Society, the German National Academy of Sciences and several awards.
