Nope, not really. With no math, the thing is, the different "branches" take up a fraction of the world. Classically you might say "If eating cake is 2 units of utility and not eating cake is 0 units, then a 50% chance of cake is 1 unit." Quantum mechanically, you'd say "If eating cake is 2 units of utility and not eating cake is 0 units, then 50% of my current measure going to eating cake is 1 unit."

This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
