Herschel Quotes

“...The Presidential election has given me less anxiety than I myself could have imagined. The next administration will be a troublesome one, to whomsoever it falls, and our John has been too much worn to contend much longer with conflicting factions. I call him our John, because, when you were at the Cul de sac at Paris, he appeared to me to be almost as much your boy as mine.

...As to the decision of your author, though I wish to see the book {Flourens’s Experiments on the functions of the nervous system in vertebrated animals}, I look upon it as a mere game at push-pin. Incision-knives will never discover the distinction between matter and spirit, or whether there is any or not. That there is an active principle of power in the universe, is apparent; but in what substance that active principle resides, is past our investigation. The faculties of our understanding are not adequate to penetrate the universe. Let us do our duty, which is to do as we would be done by; and that, one would think, could not be difficult, if we honestly aim at it.

Your university is a noble employment in your old age, and your ardor for its success does you honor; but I do not approve of your sending to Europe for tutors and professors. I do believe there are sufficient scholars in America, to fill your professorships and tutorships with more active ingenuity and independent minds than you can bring from Europe. The Europeans are all deeply tainted with prejudices, both ecclesiastical and temporal, which they can never get rid of. They are all infected with episcopal and presbyterian creeds, and confessions of faith. They all believe that great Principle which has produced this boundless universe, Newton’s universe and Herschel’s universe, came down to this little ball, to be spit upon by Jews. And until this awful blasphemy is got rid of, there never will be any liberal science in the world.

I salute your fireside with best wishes and best affections for their health, wealth and prosperity.

{Letter to Thomas Jefferson, 22 January, 1825}”

“Herschel removed the speckled tent-roof from the world and exposed the immeasurable deeps of space, dim-flecked with fleets of colossal suns sailing their billion-leagued remoteness.”
― Mark Twain

“What caused me to undertake the catalog was the nebula I discovered above the southern horn of Taurus on September 12, 1758, while observing the comet of that year. ... This nebula had such a resemblance to a comet in its form and brightness that I endeavored to find others, so that astronomers would not confuse these same nebulae with comets just beginning to shine. I observed further with suitable refractors for the discovery of comets, and this is the purpose I had in mind in compiling the catalog.

After me, the celebrated Herschel published a catalog of 2000 which he has observed. This unveiling the sky, made with instruments of great aperture, does not help in the perusal of the sky for faint comets. Thus my object is different from his, and I need only nebulae visible in a telescope of two feet [focal length].”

“[Pechblende] einer eigenthümlichen, selbstständigen metallischen Substanz bestehe. Es fallen folglich auch deren bisherige Benennungen, als: Ресhblende Eisenpecherz, hinweg, welche nun durch einen neuen ausschliessend bezeichnenden Namen zu ersetzen sind. Ich habe dazu den Namen: Uranerz (Uranium) erwählt; zu einigem Andenken, dass die chemische Ausfindung dieses neuen Metallkörpers in die Epoche der astronomischen. Entdeckung des Planeten Uranus gefallen sei.

[Pitchblende] consists of a peculiar, distinct, metallic substance. Therefore its former denominations, pitch-blende, pitch-iron-ore, &c. are no longer applicable, and must be supplied by another more appropriate name.—I have chosen that of uranite, (Uranium), as a kind of memorial, that the chemical discovery of this new metal happened in the period of the astronomical discovery of the new planet Uranus.”

“My dear nephew was only in his sixth year when I came to be detached from the family circle. But this did not hinder John and I from remaining the most affectionate friends, and many a half or whole holiday he was allowed to spend with me, was dedicated to making experiments in chemistry, where generally all boxes, tops of tea-canisters, pepper-boxes, teacups, &c., served for the necessary vessels, and the sand-tub furnished the matter to be analysed. I only had to take care to exclude water, which would have produced havoc on my carpet.”

“As an astronomer in the true sense of the term, Sir John Herschel stood before all his contemporaries. Nay, he stood almost alone.”
