My child and I couldn’t stop dancing next to an old steam pump at the Museum of Technology in Cambridge.

Great photos!

I hope that the fairing catchers will enjoy their retirement fishing with their relatives in Cochin:

Thanks for tweeting this. One trick: say ‘No’ when they ask if you want to book the 2nd appointment in the same place, because for some reason all the Cambridge sites don’t have availability for 2nd appointments.

And what do the other branches of the hyperbolas give us?
