- This follows nicely upon my previous post, in which Dan Platt stretches
- the definition of mass so as to never convert mass to energy. Now you
- are going to stretch the definition of energy so that we never have to
- convert energy to mass. You are willing to say that when we weigh atoms
- that we are weighing their energy and not their mass? This is a strange
- definition of weight. How much of what you weigh is energy, and how
- much is mass? It seems, surprisingly, that the atom has just enough
- energy that it is all released in a particular nuclear fission reaction,
- leaving only the mass behind. What about other nuclear reactions?
- Is there any mass at all in this version of the Watts theory of
- matter/energy nonconvertibility? How would you go about reconciling
- this point of view with Dan's version of the Watts argument that everything
- which you would call energy is really mass?
