Toy models
— small mathematics in a big world —

Would you like to come see some toys?
‘Toys’ here have a special sense: objects of daily life which you can find or make in minutes, yet which, if played with imaginatively, reveal surprises that keep scientists puzzling for a while.
We will see table-top demos of a diversity of such toys, in which we will notice new physical effects, from which we will try to extract some fresh mathematics.

A World From A Sheet of Paper - Tadashi Tokieda

Abstract: Starting from just a sheet of paper, by folding, stacking, crumpling, sometimes tearing, we shall explore a diversity of phenomena, from magic tricks and geometry through elasticity and the traditional Japanese art of origami to medical devices and an ‘h-principle’. Much of the show consists of table-top demonstrations, which you can try later with friends and family.

So, take a sheet of paper. . .
