A Klein bottle?

The photo is of brother Bob standing next to Dick DeBoer and his twin girls. Taken at the award ceremony for him, Dick is the EMT who watched me land and hurried over to stabilize me. In retrospect, he probably saved my life or saved me from being a quadriplegic for the rest of my life, thanks again, Dick. I never noticed before that the girls are significantly different in size.
A Klein bottle is similar to a mobious strip. The mobious strip is a strip of paper with a half twist and the ends fastened. The result is a donut shaped strip with only ONE surface, not two. A Klein bottle is a carafe shaped vessel in which the inside and the outside are the same surface. What goes inside, is also outside. Both are interesting mathematical curiosities. Very Escher.
I've finished the book on the Large Hadron Collider. What a monster. The particles journey around a 27 km beam before colliding in a detector the size of a large building. When I went to school accelerators were built on tabletops: injector accelerator and detector. The first 9 trans uranium elements were discovered in Berkley using equipment not much more complex than that. Now the Large Hadron Collider has four detectors each the size of a building each designed to investigate specific events just after the Big Bang. And life was so simple before. I'm glad I read that book although not directly concerned with String Theory, it opened my eyes to the size and benefits of the most expensive (and complex) scientific experiment to date. Or not.
One book closer to Hawaii. On to Matter/Antimatter.
Klein bottles are proof that we're all on this flight together.
