Some authors have conceptualized depression as a "depletion syndrome" because of the prominence of fatigability; they postulate that the patient exhausts his available energy during the period prior to the onset of the depression and that the depressed state represents a kind of hibernation, during which the patient gradually builds up a new story of energy.
So we find that the three possible solutions of the great problem of increasing human energy are answered by the three words: food, peace, work... Their scientific meaning and purpose now clear to me: food to increase the mass, peace to diminish the retarding force, and work to increase the force accelerating human movement.
The outward freedom that we shall attain will only be in exact proportion to the inward freedom to which we may have grown at a given moment. And if this is a correct view of freedom, our chief energy must be concentrated on achieving reform from within.
There were lots of little boys having their bar mitzvahs all over the world, and they sent me tapes of some of them that they interviewed, probably six or seven little boys, and there was something about Mendel. I just loved his little face. I loved the energy of Mendel.
I am a particle physicist, which is the nearest branch to nuclear physics. So in that sense I was the sort of right connection with the subject of nuclear energy and so on.
