Target Quotes (4 quotes)

Basic research is like shooting an arrow into the air and, where it lands, painting a target.
Quoted In A. Mackay (ed.), A Dictionary of Scientific Quotations (1991), 2.

Over the last century, physicists have used light quanta, electrons, alpha particles, X-rays, gamma-rays, protons, neutrons and exotic sub-nuclear particles for this purpose [scattering experiments]. Much important information about the target atoms or nuclei or their assemblage has been obtained in this way. In witness of this importance one can point to the unusual concentration of scattering enthusiasts among earlier Nobel Laureate physicists. One could say that physicists just love to perform or interpret scattering experiments.
Nobel Banquet Speech (10 Dec 1994), in Tore Frängsmyr (ed.), Les Prix Nobel. The Nobel Prizes 1994 (1995).

That he [Einstein] may sometimes have missed the target … as, for example, in his hypothesis of light quanta, cannot really be held against him.
From his letter proposing the young Einstein as a member of the Royal Prussian Academy of Science. As quoted in Albert Einstein: A Documentary Biography (1956), 145.

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.

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
