Shield Quotes (4 quotes)
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.”
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?”

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.
From post-flight news conference at Cape Canaveral (24 Feb 1962). 'Transcript of Glenn's News Conference Relating His Experiences on Orbital Flight', New York Times (24 Feb 1962), 14.
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.
