Who wrote "Ralph Waldo Emerson deserved to be shot?"

It was about marketing, and noted that Ralph Waldo Emerson said something along the lines of Build a better mousetrap, and the world will beat a path to your door , but that this was really terrible advice - products don't just sell the...

Re: Can one prove a being doesn't exist?

Existence is not a predicate You get into trouble when you treat existence as a property of a 'thing' which it can either have or not have. To say 'X does not exist' means you have to be really really sure what you mean by X. e.g. Santa Claus is a being who brings you presents at Christmas. Well yo...

Re: Can protons be extracted from an acid solution?

If you had all the protons from 1L of water in a sphere, you'd have about 53MC of charge in a sphere 6.2cm in radius, for a total electrostatic potential energy of 2.4e28 J, or 6 trillion megatons of TNT.
