Realistic Quotes (6 quotes)

Astonishment is the only realistic emotion.
In The Decline and Fall of Science (1976), 1.
Science quotes on:  |  Astonishment (30)  |  Emotion (106)

Does human spaceflight simply have a life of its own, without a realistic objective that is remotely commensurate with its costs? Or, indeed, is human spaceflight now obsolete?
In 'Is Human Spaceflight Obsolete?', Issues in Science and Technology (Summer 2004).
Science quotes on:  |  Commensurate (2)  |  Cost (94)  |  Human (1512)  |  Indeed (323)  |  Life (1870)  |  Objective (96)  |  Obsolete (15)  |  Remotely (2)  |  Simply (53)  |  Space Travel (23)

For the environmentalists, The Space Option is the ultimate environmental solution. For the Cornucopians, it is the technological fix that they are relying on. For the hard core space community, the obvious by-product would be the eventual exploration and settlement of the solar system. For most of humanity however, the ultimate benefit is having a realistic hope in a future with possibilities.... If our species does not soon embrace this unique opportunity with sufficient commitment, it may miss its one and only chance to do so. Humanity could soon be overwhelmed by one or more of the many challenges it now faces. The window of opportunity is closing as fast as the population is increasing. Our future will be either a Space Age or a Stone Age.
Arthur Woods and Marco Bernasconi

Realistic thinking accrues only after mistake making, which is the cosmic wisdom's most cogent way of teaching each of us how to carry on.
In Buckminster Fuller and Answar Dil, Humans in Universe (1983), 218.

The Johns Hopkins University certifies that John Wentworth Doe does not know anything but Biochemistry. Please pay no attention to any pronouncements he may make on any other subject, particularly when he joins with others of his kind to save the world from something or other. However, he worked hard for this degree and is potentially a most valuable citizen. Please treat him kindly.
[An imaginary academic diploma reworded to give a more realistic view of the value of the training of scientists.]

What happens if a big asteroid hits Earth? Judging from realistic simulations involving a sledge hammer and a common laboratory frog, we can assume it will be pretty bad.
In Geoff Tibballs, The Mammoth Book of Zingers, Quips, and One-Liners (2004), 502.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
