Talking Quotes (10 quotes)

Can imagination picture what the future of this invention is to be! … We may talk by light to any visible distance without any conducting wire.
Letter to his father (26 Feb 1880), describing his photophone research. Transcript with Bell Papers, Library of Congress.

If a lion could talk, we could not understand him.
In Philosophical Investigations (1953), trans. G. E. M. Anscombe, 223.

It is a safe rule to apply that, when a mathematical or philosophical author writes with a misty profoundity, he is talking nonsense.
In An Introduction to Mathematics (1911), 227.

People make the mistake of talking about ‘natural laws’. There are no natural laws. There are only temporary habits of nature.
In Dialogues of Alfred North Whitehead, as recorded by Lucien Price (1954), 367. As cited in G. Debrock (ed.), Process Pragmatism: Essays on a Quiet Philosophical Revolution (2003), 94.

The McCarthy period came along … and many of the other scientists who had been working on these same lines gave up. Probably saying “Why should I sacrifice myself? I am a scientist, I am supposed to be working on scientific things, so I don’t need to put myself at risk by talking about these possibilities.” And I have said that perhaps I’m just stubborn… I have said “I don’t like anybody to tell me what to do or to think, except Mrs. Pauling.”
From interview (11 Nov 1990) with Wayne Reynolds, website of the American Academy of Achievement.

The point of mathematics is that in it we have always got rid of the particular instance, and even of any particular sorts of entities. So that for example, no mathematical truths apply merely to fish, or merely to stones, or merely to colours. So long as you are dealing with pure mathematics, you are in the realm of complete and absolute abstraction. … Mathematics is thought moving in the sphere of complete abstraction from any particular instance of what it is talking about.
In Science and the Modern World: Lowell Lectures, 1925 (1925), 31.

The scientist is not much given to talking of the riddle of the universe. “Riddle” is not a scientific term. The conception of a riddle is “something which can he solved.” And hence the scientist does not use that popular phrase. We don’t know the why of anything. On that matter we are no further advanced than was the cavedweller. The scientist is contented if he can contribute something toward the knowledge of what is and how it is.
As quoted in 'Electricity Will Keep The World From Freezing Up', New York Times (12 Nov 1911), SM4.
Science quotes on:  |  Advanced (10)  |  Conception (63)  |  Contribute (10)  |  Knowledge (1128)  |  Phrase (21)  |  Popular (21)  |  Riddle (18)  |  Scientist (447)  |  Solution (168)  |  Term (87)  |  Universe (563)

Time is that which is measured by a clock. This is a sound way of looking at things. A quantity like time, or any other physical measurement, does not exist in a completely abstract way. We find no sense in talking about something unless we specify how we measure it. It is the definition by the method of measuring a quantity that is the one sure way of avoiding talking nonsense about this kind of thing.
From Relativity and Common Sense: A New Approach to Einstein (1980), 65.
Science quotes on:  |  Abstract (43)  |  Avoiding (2)  |  Clock (26)  |  Completely (19)  |  Definition (152)  |  Exist (89)  |  Find (248)  |  Kind (99)  |  Looking (25)  |  Measured (2)  |  Measurement (148)  |  Method (154)  |  Nonsense (32)  |  Physical (94)  |  Quantity (35)  |  Sense (240)  |  Sound (59)  |  Specify (6)  |  Time (439)

We can’t define anything precisely. If we attempt to, we get into that paralysis of thought that comes to philosophers… one saying to the other: “You don’t know what you are talking about!” The second one says: “What do you mean by know? What do you mean by talking? What do you mean by you?”
In 'Motion', The Feynman Lectures on Physics (1961), Vol. 1, 8-2.
Science quotes on:  |  Attempt (94)  |  Definition (152)  |  Knowledge (1128)  |  Meaning (87)  |  Paralysis (6)  |  Philosopher (132)  |  Precision (38)  |  French Saying (61)  |  Thought (374)

We don't know what we are talking about. Many of us believed that string theory was a very dramatic break with our previous notions of quantum theory. But now we learn that string theory, well, is not that much of a break. The state of physics today is like it was when we were mystified by radioactivity. They were missing something absolutely fundamental. We are missing perhaps something as profound as they were back then.
Closing address to the 23rd Solvay Conference in Physics, Brussels, Belgium (Dec 2005). Quoted in Ashok Sengupta, Chaos, Nonlinearity, Complexity: The Dynamical Paradigm of Nature (2006), vii. Cite in Alfred B. Bortz, Physics: Decade by Decade (2007), 206.

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
