In each century since the beginning of the world wonderful things have been discovered. In the last century more amazing things were found out than in any century before. In this new century hundreds of things still more astounding will be brought to light. At first people refuse to believe that a strange new thing can be done, then they begin to hope it can be done, then they see it can be done--then it is done and all the world wonders why it was not done centuries ago.
