At the start of the year, I had an urge to better understand the world around me, not the world of bits and bytes but the real world, the one of bits and bobs. I bought a book by Mark Miodownik called 'Stuff Matters', but is pretty good although I've only dipped in to it. Better still, I find that Miodownik has written buckets of stuff on materials for the Guardian, and he has also put together a two week course on steel on Edx. The course material may be targeted at a younger audience but I've just watched the first week's videos and my mind is suitably expanded. It would be cool to see more videos like these on plastics, wood, ceramics and other popular materials.
