Titel  Thoughts on discretization and tropicalization 
Sammanfattning  Discretization and tropicalization are two important procedures in contemporary mathematics. I will present them briefly and motivate why they are important. Discrete objects, like carpets and mosaics, have been around for thousands of years, but the advent of computers and digital cameras has made them ubiquitous. Tropical mathematics is by comparison a relatively new branch of mathematics. I shall compare the two and pose a philosophical/mathematical problem in relation to them.
