Platinum Quotes (6 quotes)

A metallurgist is an expert who can look at a platinum blonde and tell whether she is virgin metal or common ore.

Cavendish gave me once some bits of platinum for my experiments, and came to see my results on the decomposition of the alkalis, and seemed to take an interest in them; but he encouraged no intimacy with any one, and received nobody at his own house. … He was acute, sagacious, and profound, and, I think, the most accomplished British philosopher of his time.
As quoted in Victor Robinson, Pathfinders in Medicine (1912), 143.

The whole subject of the X rays is opening out wonderfully, Bragg has of course got in ahead of us, and so the credit all belongs to him, but that does not make it less interesting. We find that an X ray bulb with a platinum target gives out a sharp line spectrum of five wavelengths which the crystal separates out as if it were a diffraction grating. In this way one can get pure monochromatic X rays. Tomorrow we search for the spectra of other elements. There is here a whole new branch of spectroscopy, which is sure to tell one much about the nature of an atom.
Letter to his mother (18 May 1913). In J. L. Heilbron (ed.), H. G. J. Moseley: The Life and Letters of an English Physicist 1887-1915 (1974), 205.

Wollaston may be compared to Dalton for originality of view & was far his superior in accuracy. He was an admirable manipulator, steady, cautious & sure. His judgement was cool.—His views sagacious.—His inductions made with care, slowly formed & seldom renounced. He had much of the same spirit of Philosophy as Cavendish, he applied science to purposes of profit & for many years sold manufactured platinum. He died very rich.
In J. Z. Fullmer, 'Davy's Sketches of his Contemporaries', Chymia (1967), 12, 134.

[On gold, silver, mercury, platinum, palladium, rhodium, iridium, osmium:] As in their physical properties so in their chemical properties. Their affinities being weaker, (the noble metals) do not present that variety of combinations, belonging to the more common metals, which renders them so extensively useful in the arts; nor are they, in consequence, so necessary and important in the operations of nature. They do not assist in her hands in breaking down rocks and strata into soil, nor do they help man to make that soil productive or to collect for him its products.
From 13th Lecture in 1818, in Bence Jones, The Life and Letters of Faraday (1870), Vol. 1, 254.

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
