Order Of Magnitude Quotes (5 quotes)
Energy of the tides is continuously being dissipated at a rate whose order of magnitude is a billion horsepower!
In The Tides: Pulse of the Earth (1968), 133.
No one knows the diversity in the world, not even to the nearest order of magnitude. … We don’t know for sure how many species there are, where they can be found or how fast they’re disappearing. It’s like having astronomy without knowing where the stars are.
Quoted in Jamie Murphy and Andrea Dorfman, 'The Quiet Apocalypse,' Time (13 Oct 1986).
The laws of thermodynamics, as empirically determined, express the approximate and probable behavior of systems of a great number of particles, or, more precisely, they express the laws of mechanics for such systems as they appear to beings who have not the fineness of perception to enable them to appreciate quantities of the order of magnitude of those which relate to single particles, and who cannot repeat their experiments often enough to obtain any but the most probable results.
Elementary Principles in Statististical Mechanics (1902), Preface, viii.
Thus, remarkably, we do not know the true number of species on earth even to the nearest order of magnitude. My own guess, based on the described fauna and flora and many discussions with entomologists and other specialists, is that the absolute number falls somewhere between five and thirty million.
Conservation for the 21st Century
[Edward Teller is a conceptual thinker,] an ‘order of magnitude’ man. That’s his language. He’s like the architect who likes to make the big drawing, the broad sketch, and not worry himself about the plumbing details.
As quoted in Robert Coughlan, 'Dr. Edward Teller’s Magnificent Obsession', Life (6 Sep 1954), 62.
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) --
