When the rods were pushed back in and the clicking had died down, we suddenly experiences a let-down feeling, for all of us understood the language of the counter. Even though we had anticipated the success of the experiment, its accomplishment had a deep impact on us. For some time we had known that we were about to unlock a giant; still we could not escape an eerie feeling when we had actually done it. We felt as, I presume, everyone feels who has done something that he knowns will have very far-reaching consequences which he cannot foresee.
