Occasional Quotes (10 quotes)

Every teacher certainly should know something of non-euclidean geometry. Thus, it forms one of the few parts of mathematics which, at least in scattered catch-words, is talked about in wide circles, so that any teacher may be asked about it at any moment. ... Imagine a teacher of physics who is unable to say anything about Röntgen rays, or about radium. A teacher of mathematics who could give no answer to questions about non-euclidean geometry would not make a better impression.
On the other hand, I should like to advise emphatically against bringing non-euclidean into regular school instruction (i.e., beyond occasional suggestions, upon inquiry by interested pupils), as enthusiasts are always recommending. Let us be satisfied if the preceding advice is followed and if the pupils learn to really understand euclidean geometry. After all, it is in order for the teacher to know a little more than the average pupil.
In George Edward Martin, The Foundations of Geometry and the Non-Euclidean Plane (1982), 72.

Effective science began when it passed from the occasional amateur into the hands of men who made the winning of knowledge their special function or profession.
Address to 48th annual summer convention of the American Institute of Electriccal Engineers, Cleveland (21 Jun 1932), abridged in 'The Rτle of the Engineer', The Electrical Journal (1932), 109, 223.

He who works with the door open gets all kinds of interruptions, but he also occasionally gets clues as to what the world is and what might be important.

I have occasionally had the exquisite thrill of putting my finger on a little capsule of truth, and heard it give the faint squeak of mortality under my pressure.
Letter to Stanley Hart White (Jan 1929), collected in The Letters of E.B. White (1976, 1989), 85.

No other explanation of living forms is allowed than heredity, and any which is founded on another basis must be rejected. The present fashion requires that even the smallest and most indifferent inquiry must be dressed in phylogenetic costume, and whilst in former centuries authors professed to read in every natural detail some intention of the creator mundi, modern scientists have the aspiration to pick out from every occasional observation a fragment of the ancestral history of the living world.
'On the Principles of Animal Morphology', Proceedings of the Royal Society of Edinburgh (2 Apr 1888), 15, 294. Original as Letter to Mr John Murray, communicated to the Society by Professor Sir William Turner. Page given as in collected volume published 1889.

Spontaneous generation, to put the matter simply, takes place in smaller plants, especially in those that are annuals and herbaceous. But still it occasionally occurs too in larger plants whenever there is rainy weather or some peculiar condition of air or soil; for thus it is said that the silphium sprang up in Libya when a murky and heavy sort of wet weather condition occurred, and that the timber growth which is now there has come from some similar reason or other; for it was not there in former times.
De Causis Plantarum 1.5.1, in Robert Ewing Dengler (trans.) Theophrastus: De Causis Plantarum Book One: Text, Critical Apparatus, Translation, and Commentary, (1927), 31.

Stars look serene, but they are incredibly violent furnaces that occasionally erupt in incredibly violent explosions.
Epigraph in Isaac Asimov’s Book of Science and Nature Quotations (1988), 309.

The fact that nature deals the occasional death blow doesn’t hand us an excuse to imitate it.
In Terry Pratchett, Ian Stewart and Jack Cohen, The Science of Discworld (2014), 365.

The use of thesis-writing is to train the mind, or to prove that the mind has been trained; the former purpose is, I trust, promoted, the evidences of the latter are scanty and occasional.
From Preface to First Edition to Notes on the Composition of Scientific Papers (1904), v.
Science quotes on:  |  Evidence (157)  |  Mind (544)  |  Promotion (6)  |  Proof (192)  |  Purpose (138)  |  Scanty (3)  |  Thesis (10)  |  Training (39)  |  Writing (72)

There is an occasional glimmer of fertility [as compounds], the chemical equivalent of a blade of grass [in a desert]. So, gone … is the justification for “inert.” [Group 0 elements] are now known collectively as the noble gases, a name intended to imply a kind of chemical aloofness rather than a rigorous chastity.
In The Periodic Kingdom: A Journey Into the Land of the Chemical Elements (1995), 9.

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
