Wondrous Mathematics: The curious world of four-dimensional geometry

From 35C3 Wiki

Description (NOT in M3, but in 14/15) You couldn't tie your shoelaces if we lived in four dimensions! And spheres would be much smaller and spikier. We'll take you on a visual tour of these and other curious phenomena unfolding in four dimensions.

Subtitle talk in room 14/15 (NOT in M3 as previously announced)

Ends at 2018/12/29 02:00
Duration 60 minutes
Location Room:Seminar room 14-15

Important update. Because of an unfortunate collision among the available rooms, the 4d talk will NOT take place in the afternoon. Instead it takes place in the night of Day 2 to Day 3 at 1:00 after the Mondnacht session in seminar room 14/15 (NOT in M3 as previously announced). We're very sorry for this rescheduling. We didn't find any other solution. If the new slot is too late for you, then come to us and have a chat in a small group! We're often sitting by our assembly. In case of doubt call us at +47 176 95110311.

The space we live in is three-dimensional. But mathematically, four dimensions can be just as easily defined as three dimensions. In the talk, we'll give an accessible introduction to four-dimensional thinking. We'll discuss how to imagine four dimensions, see examples of beautiful four-dimensional shapes, learn how to glue three-dimensional forms to four-dimensional ones and discover what's special about four dimensions. We'll also explore a four-dimensional labyrinth.

There's some chance that you'll leave the talk with a new favourite platonic solid.

The talk doesn't require any mathematical prerequisites. Exactly two formulas will appear. There will be pretty pictures. Bring your kids (age 12 and above), if they understand English! If you have seen the installment of this talk at the 33c3, then skip this talk, there is very little new material.
