Shield Quotes (8 quotes)
…continental blocks can join and rift at random.… The fact that two provinces of the Canadian Shield have been together during post-Cambrian time does not necessarily mean that they were formed close together or that the sediments lying in one province were derived from the province now beside it.
In 'The Effect of New Orogenetic Theories Upon Ideas of the Tectonics of the Canadian Shield', collected in Royal Society of Canada, Special Publication No. 4, The Tectonics of the Canadian Shield (1962), 135-138. As quoted and cited in Biographical Memoirs of Fellows of the Royal Society (Nov 1995), 41, 544. This quote’s relevance is to show that after some years of reluctance, Wilson did eventually accept the idea of continental drift.
Chemistry is not a primitive science like geometry and astronomy; it is constructed from the debris of a previous scientific formation; a formation half chimerical and half positive, itself found on the treasure slowly amassed by the practical discoveries of metallurgy, medicine, industry and domestic economy. It has to do with alchemy, which pretended to enrich its adepts by teaching them to manufacture gold and silver, to shield them from diseases by the preparation of the panacea, and, finally, to obtain for them perfect felicity by identifying them with the soul of the world and the universal spirit.
From Les Origines de l’Alchimie (1885), 1-2. Translation as quoted in Harry Shipley Fry, 'An Outline of the History of Chemistry Symbolically Represented in a Rookwood Fountain', The Journal of Industrial and Engineering Chemistry (1 Sep 1922), 14, No. 9, 868. From the original French, “La Chimie n’est pas une science primitive, comme la géométrie ou l’astronomie; elle s’est constituée sur les débris d’une formation scientifique antérieure; formation demi-chimérique et demi-positive, fondée elle-même sur le trésor lentement amassé des découvertes pratiques de la métallurgie, de la médecine, de l’industrie et de l’économie domestique. Il s’agit de l’alchimie, qui prétendait à la fois enrichir ses adeptes en leur apprenant à fabriquer l’or et l’argent, les mettre à l’abri des maladies par la préparation de la panacée, enfin leur procurer le bonheur parfait en les identifiant avec l’âme du monde et l’esprit universel.”
He scarce had ceased when the superior fiend
Was moving toward the shore; his ponderous shield
Ethereal temper, massy, large and round,
Behind him cast; the broad circumference
Hung on his shoulders like the moon, whose orb
Through optic glass the Tuscan artist views
At evening from the top of Fésolè,
Or in Valdarno, to descry new lands,
Rivers or mountains in her spotty globe.

I have taken your advice, and the names used are anode cathode anions cations and ions; the last I shall have but little occasion for. I had some hot objections made to them here and found myself very much in the condition of the man with his son and ass who tried to please every body; but when I held up the shield of your authority, it was wonderful to observe how the tone of objection melted away.
Letter to William Whewell, 15 May 1834. In Frank A. J. L. James (ed.), The Correspondence of Michael Faraday (1993), Vol. 2, 186.
I was working with a Crookes tube covered by a shield of black cardboard. A piece of barium platino-cyanide paper lay on the bench there. I had been passing a current through the tube, and I noticed a peculiar black line across the paper. …
The effect was one which could only be produced in ordinary parlance by the passage of light. No light could come from the tube because the shield which covered it was impervious to any light known even that of the electric arc. …
I did not think; I investigated. …
I assumed that the effect must have come from the tube since its character indicated that it could come from nowhere else. … It seemed at first a new kind of invisible light. It was clearly something new something unrecorded. …
There is much to do, and I am busy, very busy. [Describing to a journalist the discovery of X-rays that he had made on 8 Nov 1895.]

My greatest hope for a future without another Deepwater Horizon disaster lies in our schools, living rooms and community centers, not in boardrooms, political chambers and big industry. If this happens again, we won’t have the luxury of the unknown to shield us from answering “Why?”

The first watch of night is given
To the red planet Mars.
Is it the tender star of love?
The star of love and dreams?
Oh. no! from that blue tent above,
A hero’s armour gleams.
And earnest thoughts within me rise,
When I behold afar,
Suspended in the evening skies,
The shield of that red star.
O star of strength! I see thee stand
And smile upon my pain;
Thou beckonest with thy mailèd hand,
And I am strong again.

Suspended in the evening skies,
The shield of that red star.

And smile upon my pain;
Thou beckonest with thy mailèd hand,
And I am strong again.

There was some doubt whether the heat shield had been damaged … This could have been a bad day all the way around if this had been the case.

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.
