silver mobius

ah, lifetime learning!  just this week i made a new entry in my "what did i learn today?" journal.  thursday, may 7th:  mobius.  it wasn't until i saw a new silver sculpture that i learned this concept which is functional and also beautiful.  the mobius strip is defined as, "a surface with only one side and one boundary that has the mathematical property of being non-orientable as a ruled surface.  it was discovered independently by german mathematicians august ferdinand mobius and johann benedict listing in 1858."  (i can imagine them twising paper in their think-tanks saying, "no, you go ahead, your name sounds better than 'listing'...")
