Mobius Strip

Eric gleefully describes his scarf which is also a mobius strip which has a mathematical property of having a non-orientable surface: "You can splice two together and get a klein bottle" he points out. (A klein bottle, dear reader, is a two-dimensional manifold against which a system for determining a normal vector cannot be consistently defined). Like father, like son.

Eric and I have breakfast and catch each other up on various activities: Ben is somehow a Jr in college and contemplating an engineering PhD; Jonah is committed to drama and Isabel is evolving. It's about growing up.
