Science Quotes by Johann Gottfried Galle (1 quote)
Sir,—The Planet [Neptune] whose position you marked out actually exists. On the day on which your letter reached me, I found a star of the eighth magnitude, which was not recorded in the excellent map designed by Dr. Bremiker, containing the twenty-first hour of the collection published by the Royal Academy of Berlin. The observation of the succeeding day showed it to be the Planet of which we were in quest.
— Johann Gottfried Galle
Letter, from Berlin (25 Sep 1846). In John Pringle Nichol, The Planet Neptune: An Exposition and History (1848), 89. Galle thus confirmed the existence of the planet Neptune, found at the position predicted in a letter he had just received from Urbain Le Verrier.

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.
