Is there someone out there who could explain string theory and loop quantum gravity to me in plain English, please? I have no mathematical ability whatsoever, so I'm looking for an explanation of the concepts. Numbers leave me scratching my head. I am not suggesting that my numerical stupidity is anything to be proud of; it is simply a fact. I have tried many times over two decades to grasp quadratic equations and failed. You see my problem. Pleease help. Kate.
