Science Quotes by Wilhelm Konrad Roentgen (1 quote)

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.]
— Wilhelm Konrad Roentgen
In H.J.W. Dam in 'The New Marvel in Photography", McClure's Magazine (Apr 1896), 4:5, 413.

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
