Everything is connected and different: the Pauli exclusion principle
Everything is connected and my mind is blown. I'm a fan of systems theory and the idea that everything is connected. When Brian Cox explains it this way, however, we move beyond the cool, hippie, "yeah, man, it's all connected and you're my brother-sister-tree-stone-mother-life-force-cousin" and into the scary inexplicable vastness of the weird. Don't believe me? Just watch.
Are you rubbing something right now and warming it up? I thought so. My electrons feel different. Now stop it or you'll go blind.
