I have edited for a little while without signing-in and feel that since I use WP a lot I should pay back a little. I've just created my sign-in and will be keeping it simple. I have a (slightly ageing) science doctorate and I'm interested in issues where science and the everyday world meet. I am not a leading edge expert on anything, really, but I hope to keep a weather eye out for articles I might be able to make little improvements to. Richard3444 (talk) 17:48, 4 October 2022 (UTC)
