The biggest circus in chess is around 1200. Some days, you play like a 400 and all your pieces disappear. Other days you are 1800 level, converting games flawlessly.

Friday fun times!! Who knows where this ridiculous rock comes from? Having my first play around with some 3D photo capture! Just wait for those garnets! Low res with the phone cam for now. But playing with a decent camera next! #geology #rocks #metamorphism #ore #ZeissNatRes

Day 51: Migmatite formed after interbedded psammite (left) and pelite (right). Melt escaping along the light-coloured channel (diagonal from the bottom right corner). At the metapsammite the channel branches because the higher competence inhibits migration. #100DaysofGeoscience

I wonder how Bill Gates is going to spend his first day in control of Margaret Keenan, 90, from Coventry.

Has it been a while since you’ve seen a garnet as big as a fist? Let me fix that for you...🤓

Interested in the scales of equilibrium in granulites? How are those pretty corona textures and compositional layers formed and preserved? Have a squiz. A recent one with @Wonkiergruff1, Katy Evans, Saibal Gupta and @chrisfpclark
