As never before, the work of the engineer is basic to the kind of society to which our best efforts are committed. Whether it be city planning, improved health care in modern facilities, safer and more efficient transportation, new techniques of communication, or better ways to control pollution and dispose of wastes, the role of the engineer—his initiative, creative ability, and hard work—is at the root of social progress.

Certainly, speaking for the United States of America, I pledge that, as we sign this treaty in an era of negotiation, we consider it only one step toward a greater goal: the control of nuclear weapons on earth and the reduction of the danger that hangs over all nations as long as those weapons are not controlled.

Commitment to the Space Shuttle program is the right step for America to take, in moving out from our present beach-head in the sky to achieve a real working presence in space—because the Space Shuttle will give us routine access to space by sharply reducing costs in dollars and preparation time.

I have decided today that the United States should proceed at once with the development of an entirely new type of space transportation system designed to help transform the space frontier of the 1970s into familiar territory, easily accessible for human endeavor in the 1980s and ’90s. This system will center on a space vehicle that can shuttle repeatedly from Earth to orbit and back. It will revolutionize transportation into near space, by routinizing it. It will take the astronomical costs out of astronautics. In short, it will go a long way toward delivering the rich benefits of practical space utilization and the valuable spin-offs from space efforts into the daily lives of Americans and all people.

If more of our resources were invested in preventing sickness and accidents, fewer would have to be spent on costly cures. … In short, we should build a true “health” system—and not a “sickness” system alone.

Listen, I don't know anything about polygraphs and I don’t know how accurate they are, but I know they’ll scare the hell out of people.

Neil and Buzz, I am talking to you by telephone from the Oval Office at the White House, and this certainly has to be the most historic telephone call ever made. Because of what you have done, the heavens have become a part of man’s world. As you talk to us from the Sea of Tranquility, it inspires us to redouble our efforts to bring peace and tranquility to Earth.

Peace means creative giving, making a contribution to the betterment of our own people and to the betterment of people throughout the world. And who better understands that than the men and women of American agriculture?

The great question. … is, shall we surrender to our surroundings, or shall we make our peace with nature and begin to make reparations for the damage we have done to our air, our land, our water? Restoring nature to its natural state is a cause beyond party and beyond factions. It has become a common cause of all the people of America.

The sky is no longer the limit.

This is the greatest week in the history of the world since the Creation.

[Richard Nixon] is the kind of politician who would cut down a redwood tree, and then mount the stump and make a speech for conservation.

The aether: Invented by Isaac Newton, reinvented by James Clerk Maxwell. This is the stuff that fills up the empty space of the universe. Discredited and discarded by Einstein, the aether is now making a Nixonian comeback. It’s really the vacuum, but burdened by theoretical, ghostly particles.

In the fall of 1972 President Nixon announced that the rate of increase of inflation was decreasing. This was the first time a sitting president used the third derivative to advance his case for reelection.
