Сторінка 5 - To make available for life every place where life is possible. To make inhabitable all worlds as yet uninhabitable, and all life purposeful.
Сторінка 178 - ... sounding system consisting of a small solid-propellant research rocket launched from a large plastic balloon. The rocket is fired near the maximum altitude of the balloon flight. It is a relatively mobile rocketsounding system, and has been used extensively from shipboard. Roentgen — That amount of x or gamma radiation sufficient to produce ions carrying one electrostatic unit of charge in one cm* of air.

Сторінка 29 - Also, certain types of facilities require a certain size of population. For example, a symphony orchestra cannot exist in a small town. There is also the problem of size versus number. For example, many areas of the American Midwest have a large number of small colleges, each with 1,000 or 2,000 students. They all have libraries with more or less the same basic books. In a way, this large number of small colleges creates heterogeneity, but in another sense, a small number of large universities can...
Сторінка 178 - The newton is that force which gives to a mass of 1 kilogram an acceleration of 1 meter per second per second.

Сторінка 170 - We will be in a position to first invent new cultural patterns and new social philosophies, then choose material conditions and community design to fit the desired cultural goals and philosophies. This new vista, suddenly open, changes our entire outlook on the future, not only for those who eventually want to live in extraterrestrial communities but also for those who want to remain on the Earth. In the future, the Earth might be looked at as an uncomfortable and inconvenient place to live as compared...
