I thought I was the only one who couldn't pick up a dictionary or encyclopaedia without spending the next hours following trails I never intended to follow. Now I know there is a name for this, even if it is stretching the physics concept of random motion of molecules. Am I a molecule, are you a molecule, are we all living in a giant's thumbnail? Anyone managed to sort out the Theory of Everything yet? How many more quantum leaps can we make? Am I indulging in Brownian motion now? Aren't words wonderful?
