The President. I can see that people are streaming in to our virtual room, so I'm going to get started. A very warm welcome to you all and to the new session of meetings. We are delighted to bring you the first meeting of the 2020/2021 session via webinar, and it's just great that so many of you can join us for this new experience of the RAS Ordinary Meetings on-line. Without further ado then, we will begin the programme for this meeting.
