Oslo!

I'm headed south across Europe. Where should I go? TED audition: http://talentsearch.ted.com/video/Derek-Muller-The-key-to-effecti;TEDSydney I've seen the Celcius thermometer and his house, Paul Hewitt, the Nobel Peace Prize Museum, learned that apples from China are oranges, where the @ and & symbols come from, went rock climbing, got a haircut, trimmed my beard. Busy times!
