I was going to do Part II on why their are three dimensions of space and one of time. Unfortunately, it turns out I’ve got a lot more to say about this than I realised and it’s turning into a bit of an incoherent ramble. That might be quite suitable for a TFTD blog, but I’d like to try and reorganise my writing into something a bit more readable.
In the meantime, here’s a pretty picture of the Pleiades, or Seven Sisters, take the other night.
The blue wispy bits around the stars aren’t photographic artefacts. They’re real clouds of gas and dust around the young bright stars.

And here’s the Triangulum Galaxy. Taken the same night.
