I'm not a physicist, but I've got some views on string theory that I'd like to share. Here goes:
Brad's String Theory: Axiom I While in motion, strings will become untied, regardless of advanced techniques employed to fasten them. Brad's String Theory: Axiom II When at rest (i.e. upon completion of aforementioned motion), strings will be resistant to any attempt at unfastening.
These statements are, to best of my knowledge, universally true, based on my experiences during daily runs for the past few years.
