Another periodic surface image
This is a follow-up to Visualisation of periodic surfaces. A while ago I saw this 3D printed Gyroid model advertised online and couldn’t resist it. Design by Bathsheba Grossman, printed on demand by Shapeways.

Foucault's pendulum
I visited the Panthéon yesterday, and saw the original Foucault’s pendulum. Well, sort of. It’s the same location, but it got taken down when the Panthéon became a church again for a while, and was then restored, and then the wire broke and they had to replace it. And at some point the original 28kg bob was replaced with one almost twice as heavy. So it’s a bit like the story about the axe that’s had three new handles and two new heads…

Here are some images I generated while I was writing my PhD thesis. These are all the solutions of simple equations involving trig functions, but are close to and share symmetry and topology with periodic minimal surfaces, which are difficult to calculate and work with.
