Paraboloids and The Building which Set Things on Fire


The building in London at 20 Fenchurch Street started to set things on fire! But it could have been worse. I use a paraboloid to set other things on fire.

Oh, and theres a maths proof.

If youre a masters or PhD student from an ESA member state, and zero-g sounds like your thing, have a look at the Fly Your Thesis program: www.esa.int/Education/Fly_Your_Thesis — the 2017-18 submissions are closed, but that just gives you time to start planning for next year…
