The factor most ignored in discussing interstellar flight is the kinetic energy that must be invested in the ship to make its tons of matter move at a substantial fraction of the speed of light.
It is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe.
Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel... We find it in the delightful myth of Antaeus, who derives power from the earth; we find it among the subtle speculations of one of your splendid... Throughout space there is energy. Is this energy static or kinetic! If static our hopes are in vain; if kinetic - and this we know it is, for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
Inspiration does not come like a blot, nor is it kinetic energy striving, but it comes to us slowly and quietly all the time.
Credentials are like potential energy, the compliments of a name on paper, in documents, word of mouth, but faith is like kinetic energy, the motion and the force that which is witnessed. Hence in the end it is the faith rather than the credentials that really takes you places.
The whole mass of any body is just the mass of ether surrounding the body which is carried along by the Faraday tubes associated with the atoms of the body. In fact, all mass is mass of the ether; all momentum, momentum of the ether; and all kinetic energy, kinetic energy of the ether, This view, it should be said, requires the density of the ether to be immensely greater than that of any known substance.
For 'Star Wars' I had to develop a whole new idea about special effects to give it the kind of kinetic energy I was looking for. I did it with motion-control photography.
O. Hahn and F. Strassmann have discovered a new type of nuclear reaction, the splitting into two smaller nuclei of the nuclei of uranium and thorium under neutron bombardment. Thus they demonstrated the production of nuclei of barium, lanthanum, strontium, yttrium, and, more recently, of xenon and caesium. It can be shown by simple considerations that this type of nuclear reaction may be described in an essentially classical way like the fission of a liquid drop, and that the fission products must fly apart with kinetic energies of the order of hundred million electron-volts each.
Hopefully the process is to spot things that would be grist for the funny mill. In some respects, the heavier subjects are the ones that are most loaded with opportunity because they have the most - you know, the difference between potential and kinetic energy? - they have the most potential energy, so to delve into that gives you the largest combustion, the most interest. I don't mean for the audience. I mean for us. Everyone here is working too hard to do stuff we don't care about.
