**I don’t think I need to say more about Prof. Conway, but if you are interested in more details, please check wikipedia page here:**

**here are the title and abstracts**

In 1899 Frank Morley noticed that the points of intersection of the adjacent angle trisectors form an equilateral triangle. Since then, proofs of various levels of complexity have been given, and in this colloquium Professor Conway will present a surprisingly simple proof discovered by himself. In addition, Professor Conway will introduce a new theorem of himself on equilateral triangles and the subtle mathematics behind it.
