I was catching up on a few of the TED Conference podcast videos this weekend, one of which was, Steven Cowley: Fusion is energy’s future. It’s a great (and scary) presentation on why nuclear fusion will be one of our only solutions to the fossil fuel crisis. One part that grabbed my attention was where he he explained one of the easiest methods of creating a fusion reaction:

There is one reaction, that’s probably one of the easiest fusion reactions to do. It’s between two isotopes of hydrogen – deuterium …and tritium. These two nucleii, when they’re far apart, are charged. And you push them together and they repel …but when you get them close enough together, something called the Strong Force starts to act and pulls them together. So most the time they repel, but you get them closer and closer and closer and at some point the Strong Force grips them together.

That sounded like a great metaphor for some relationships I know, but prior to the fusion clip, I watched James Geary, metaphorically speaking, so maybe that had something to do with it.
