My name is Peter and I grew up in Switzerland. I\u2019m a Christian and particle physicist by education. If you\u2019ve already read some posts, you\u2019ll not be surprised that I\u2019m interested in a wide range of topics including physics, theology, and computer science. I created this blog in my spare time after Dectris agreed to sponsor the hardware for a world record computation of \u03c0. The texts on this blog therefore do not necessarily reflect the view of my employer.<\/p>\n

\"\"<\/a>
NZZ Online Screenshot, March 22, 2017<\/figcaption><\/figure>\n

My interest in \u03c0 dates back to my time at the Alte Kantonsschule in Aarau, where my math teacher had fixed several printouts full with digits of \u03c0 at the walls of our class room. My friend and me tried to memorise the first digits of \u03c0, but I never managed to get beyond the 20 first digits. At the time of writing I\u2019m working for Dectris developing fast digital X-ray detectors.<\/p>\n

If you ever wondered about my profile’s nickname Pipi<\/em>, let me clarify that it has nothing to do with \u03c0. This name was invented by my one and a half year old niece to simplify the pronunciation of my first name.<\/p>\n","protected":false},"excerpt":{"rendered":"
