# Issue 43

June 2007
If you thought you knew what geometry is all about, then this issue of
Plus may change your mind. We explore a strange point-less geometry of spacetime, find out about hyperbolic geometry's amazing fractals, celebrate a geometric formula named after Leonhard Euler, the most prolific mathematician of all time, and try to calculate pi. This issue also contains the first ever Plus
teacher package and, to celebrate our tenth birthday, continues our series on the history of Plus. |
