Stand-up Maths

Read the Nature paper for yourself:

"Scutoids are a geometrical solution to three-dimensional packing of epithelia"

Thanks to Laura and Clara for helping me with the video!

You can download Laura's model for free or order a print from Shapeways:

Images of cells and stuccoed are all from "Scutoids are a geometrical solution to three-dimensional packing of epithelia".

CORRECTIONS

- Yes, I pronounce it SCOO-toid, SCOW-toid, SCOE-toid etc. Sorry. It's new! I actually think ES-COE-TOID is the most correct.

- Alex Sweeney noticed that when I describe a prism I say it has rectangle faced sides. But that is only true of right prisms, in general a prism has side faces which are parallelograms. When I later talk about prismatoids I realised I had to be more general and said the sides are faces with three or four edges. But I should have done that earlier.

- Let me know if you spot anything!
