Event description

The crystalline materials known as Perovskites make up 38% of the volume of the earth. Moreover, they have many very important practical uses, for example in electronics, ultrasonics and in thermal sensing devices. So what are they exactly? Mike Glazer will explain how tiny changes in their crystal structures can lead to such a vast array of different properties and why they are so important in our daily lives.

This Discourse is supported by the Bragg Lecture Fund.

About the speaker

Mike Glazer is an Emeritus Professor of the Oxford University Department of Physics. He is the Vice President of the International Union of Crystallography and recently wrote 'A Very Short Introduction to Crystallography' for Oxford University Press.

More about Discourses

Discourses are one of the Ri’s oldest and most prestigious series of talks. Since 1825, audiences in the theatre have witnessed countless mind-expanding moments, including the first public liquefaction of air by James Dewar, the announcement of the electron by J.J. Thomson and over 100 lectures by Michael Faraday. In more recent times, we have had Nobel laureates, Fields medal winners, scientists, authors and artists – all from the cutting-edge of their field. Discourses are an opportunity for the best and brightest to share their work with the world.

Steeped in nearly two centuries of tradition, a Discourse is more than just a lecture. To keep the focus on the topic, presenters begin sharply at 7:30pm without introduction and we lock the speaker into a room ten minutes ahead of the start (legend has it that a speaker once tried to escape!) We also ask guests to dress smartly to add to the sense of occasion.

Discourses are free for members - consider joining today.

Food and Drink

The Atrium cafe will be open before and after the talk. Check out the delicious menu and call 020 7670 2973 or email to reserve your table.

There will also be a cash bar on the Mezzanine before the Discourse, where you can relax, meet likeminded people with an interest in science, and have a drink.

Dress code

The dress code for this event is smart (ties optional, no jeans or trainers). Please note, if you are not dressed smartly you may be asked to sit in the gallery.

Timing note

Please be aware that this Discourse starts at 7.30pm, but all attendees must be seated in the theatre by 7.20pm. This is half an hour earlier than previous Discourses.
