Today we went to Neuchatel and visited the company Spectratime, which creates atomic clocks that are used for GPS systems among other things.
The light from a rubidium discharge lamp shines like bright purple fluorescent light, it’s pretty fascinating! Apart from that I’ve learned a lot and realized how much effort it needs to test something (for months) before it can be sent into outer space! http://www.spectratime.com
And finally I got good news: I’ve passed my post-graduate studies and am getting my diploma as a ward-leader in January 🙂
