Over five years I’ve been reading all the SF Masterworks, about 188 books in total. Read in fairly random order, with preference for authors I’d not read before. Not a bad one amongst them, and plenty of surprises

Why, in 2000, did Blair approve the building of an expensive synchrotron at Didcot (Harwell, near Oxford) and not Daresbury (near Manchester)?

Why the South and not in the North?

Anyone want a thread on the story, with archive docs?

I promise to be rude about Oxford profs… Let’s start: what is it?

Synchrotrons accelerate particles (electrons) which when made to follow a constrained path produce intense, useful electromagnetic radiation (X-rays, UV, light etc)

You can use this light etc to probe molecular structures & do lots of good science
