København, Danemark
On the way home from Technical Advances in Lattice Field Theory I stopped in Copenhagen. The city is beautiful, although it doesn’t get much light in early December. I made some nice friends at a hostel, enjoyed some walking tours, and had a great hotdog. Tivoli Gardens is open for Christmas-time. We rode the roller coaster while wearing virtual-reality headsets, which was phenomenal and so obviously the future it’s hard to overstate.
