5 December 17

Today marks the birthday of theoretical physicist Werner Heisenberg (1901-1976), who is most famous for developing the Heisenberg Uncertainty Principle. (Or maybe it was someone else.) My "reindeer mistletoe" tie is a new gift from a young man named Ben who lives across the street and visits us daily when his school bus driver drops him off at our front door! The tie is clearly relevant to the Christmas season, but its connection to Werner Heisenberg is completely uncertain.
