Phase Diagram

phase_diagramFor those who have a thirst for something physics-y to follow the tomato chutney post, here’s a decorated physics diagram I made in Matlab this morning. Click for a larger view. It’s the phase diagram of interesting black hole transitions* (that I co-discovered 14 years ago) associated with part of the story I mentioned last month. On the right of the line you have small black holes favoured (of a given charge, so move horizontally), and on the left side of the line the system favours large black holes and so when you cross the line you have a sudden jump from one type to the other. That second order critical point I talked about there is the end of the line of first order points. The blue dot. Above there, you cross over smoothly from small to large holes. The blue dot is the border between the two cases.

It is a bit like having steam (or water vapour) on the left and liquid water on the right, and crossing the line is what you call boiling. The second order point is the place […] Click to continue reading this post →

Last night – late last night – I decided to work on another food item that allows me to use them up and save this glorious condensation of Summer for a later time. I decided to make a tomato chutney. Well, I’m making two. I wanted to take the yellower tomatoes to make one with a lighter colour and flavour, and I will (later tonight perhaps?) make another, darker one with red tomatoes (with a little pepper from the garden for warmth).

A chutney is simple. It’s a bit like a savoury jam but even easier. I halved the little yellow pear variety tomatoes, and chopped a yellow onion – about half as much in volume as I had tomato. (Some extra tomatoes showed up late – I found a few green […] Click to continue reading this post →
