Socks (sorry sockophobes) - I am developing a dangerous addiction to knitting socks, and an even more dangerous (and expensive) one to buying sock yarn. But it all so lovely and colourful and just a few quid for enough to knit a pair, and socks are such a handy portable knitting project ideal for train journeys, never mind that my stash looks like I am planning to keep the British Army in socks this winter (assuming they like multi-coloured ones) and pandas are going hungry as I buy up all their bamboo in the form of needles. OK so I might have to send O up chimneys to pay my Violet Green bill but that's a small sacrifice compared to the joy of hoarding all those lovely brightly coloured balls of wool, and fondly imagining I will transform them all into lovely socks in time for Christmas.
Thermodynamics - gotta love a discipline that having set up 3 rules, decided there was another more important one so called it the zeroth law. Bless. I am really struggling with one of my courses, so much so that I have actually been happy to see some thermodynamic equations. So much of the course feels like an assemblage of facts describing trends (it's the worst bits of inorganic chemistry magnified), it's nice to have some equations to get ones teeth into. You know where you are with an equation. All together now, heat can't move from a cooler to a hotter.
