Fighter Jet Quotes (1 quote)
Technology is … “practical arts”; in that guise, technology has been around for a good two million years. The Pleistocene spearpoint flaked from pink flint…was the high technology of its day, as sophisticated and effective as a samurai sword or a fighter jet.
In 'Introduction', Visions of Technology (1999), 21-22

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
