Development of Finite Difference Schemesand Numerical Simulation of Neutrons Or Radiation Transport Processes Under Condition of Strong Interaction with Matter

Whilst Copernicus has persuaded us to believe, contrary to all the senses, that the earth does not stand fast Boscovich has taught us to abjure the belief in the last thing that stood fast of the earth—the belief in "substance," in "matter," in the earth-residuum, and particle-atom: it is the greatest triumph over the senses that has hitherto been gained on earth. One must, however, go still further, and also declare war... against the "atomistic requirements" which still lead a dangerous after-life in places where no one suspects them, like the more celebrated "metaphysical requirements": one must also above all give the finishing stroke to that other and more portentous atomism which Christianity has taught best and longest, the soul-atomism. Let it be pemitted to designate by this expression the belief which regards the soul as something indestructible, eternal, indivisible, as a monad, as an atomon : this belief ought to be expelled from science!

The space of time in which a great work can now be accomplished is not marvellous. Brain, muscle, materials, and the means of rapid transport are instantly at command. If one has capital and a well-considered plan, the thing does itself. But that which is wonderful and which I can scarcely believe, although I have been in the midst of it, is the noble, artistic result which has come from the work of American artists who have had only a few months' time to prepare those very designs for the great buildings of the Exposition which have actually been executed with little change from the sketches which were presented in February, 1891.

Transport of the mails, transport of the human voice, transport of flickering pictures — in this century, as in others, our highest accomplishments still have the single aim of bringing men together.
