John F. Kennedy:
No man can fully grasp how far and how fast we have come, but condense, if you will, the 50,000 years of man’s recorded history in a time span of but a half century. Stated in these terms, we know very little about the first 40 years, except at the end of them advanced man had learned to use the skins of animals to cover them. Then, about 10 years ago, under this standard, man emerged from his caves to construct other kinds of shelter. Only five years ago, man learned to write and use a cart with wheels. Christianity began less than two years ago. The printing press came this year, and then less than two months ago, during this whole 50-year span of human history, the steam engine provided a new source of power.
Newton explored the meaning of gravity. Last month, electric lights and telephones and automobiles and airplanes became available. Only last week did we develop penicillin and television and nuclear power, and now, if America’s new spacecraft succeeds in reaching Venus, we will have literally reached the stars before midnight tonight.
