The future of humanity is uncertain, even in the most prosperous countries, and the quality of life deteriorates; and yet I believe that what is being discovered about the infinitely large and infinitely small is sufficient to absolve this end of the century and millennium. What a very few are acquiring in knowledge of the physical world will perhaps cause this period not to be judged as a pure return of barbarism.
There are two kinds of mines; one is the personnel mine and the other is the vehicular mine. When we come to a mine field our infantry attacks exactly as if it were not there. The losses we get from personnel mines we consider only equal to those we would have gotten from machine guns and artillery if the Germans had chosen to defend that particular area with strong bodies of troops instead of with mine fields. The attacking infantry does not set off the vehicular mines, so after they have penetrated to the far side of the field they form a bridgehead, after which the engineers come up and dig out channels through which our vehicles can go.
