4/ so this one time I helped build a timber frame house and the lead timber framer tried to convince the couple for whom the house was built that it was Anglo Saxon tradition that they each had to climb the frame and piss off it to the east & west https://twitter.com/GeoGDF01/status/1262730583324741635 …

7/ well, the way that the actual IRL eutectic chart works is that temperature is measured on the vertical axis and percent carbon / percent iron on the horizontal axis, and as you heat and add carbon to iron it moves around the 2-D phase space >>> https://twitter.com/yorrick09/status/1262742019266342913 …

9/ and so these different structures are called "allotropes" and if you cool slowly the carbon migrates back out of the steel cubic structure ...but if you cool QUICKLY the sort of Brownian-motion readjustment doesn't have a chance to happen and the Fe cage shrinks rapidly >>
