Herschel Quotes
Mr. Herschel ... brought with him the calculations of the computers, and we commenced the tedious process of verification. After a time many discrepancies occurred, and at one point these discordances were so numerous that I exclaimed, "I wish to God these calculations had been executed by steam," to which Herschel replied, "It is quite possible."
Charles Babbage
In conclusion, it appears to me that nothing can be more improving to a young naturalist, than a journey in distant countries. It both sharpens, and partly likewise allays that want and craving, which, as Sir J. Herschel remarks, a man experiences although every corporeal sense is fully satisfied. The excitement from the novelty of objects, and the chance of success, stimulate him to increased activity. Moreover as a number of isolated facts soon become uninteresting, the habit of comparison leads to generalization. On the other hand, as the traveller stays but a short space of time in each place, his descriptions must generally consist of mere sketches, instead of detailed observation. Hence arises, as I have found to my cost, a constant tendency to fill up the wide gaps of knowledge, by inaccurate and superficial hypotheses.
Charles Darwin
Karl Marx was born at Trier on 5 May 1818, the child of Jewish parents with a long rabbinical tradition on both sides. His grandfathers were rabbis; his father, a well-to-do lawyer, changed his first name from Herschel to Heinrich and adopted Protestantism, which in Prussia was a necessary condition of professional and cultural emancipation.

But in life, as we are cognizant of it, mental development can go but a little way. The mind hardly begins to awake ere the bodily powers decline - it but becomes dimly conscious of the vast fields before it, but begins to learn and use its strength, to recognize relations and extend its sympathies, when, with the death of the body, it passes away. Unless there is something more, there seems here a break, a failure. Whether it be a Humboldt or a Herschel, a Moses who looks from Pisgah, a Joshua who leads the host, or one of those sweet and patient souls who in narrow circles live radiant lives, there seems, if mind and character here developed can go no further, a purposelessness inconsistent with what we can see of the linked sequence of the universe.
Henry George
According to Herschel, the sun consisted of three essentially different parts. First, there was a solid nucleus, non-luminous, cool, and even capable of being inhabited. Second, above this was an atmosphere proper; and, lastly, outside of this was a layer in which floated the clouds, or bodies which gave to the solar surface its intense brilliancy.
William Herschel
Herschel's argument was... Since with such a telescope one can see a star ten times as far off as is possible to the naked eye, this telescope has the power of penetrating into space ten times farther than the eye alone. But this number ten, also, expresses the ratio of the diameter of the objective to that of the pupil of the eye, consequently the general law is that the space-penetrating power of a telescope is found by dividing the diameter of the mirror in inches by two-fifths. The diameter of the pupil of the eye (two fifths of an inch) Herschel determined by many measures.
William Herschel
The Illustrated Review... to which we are indebted for the preceding statements, remarks that, since the death of Sir John Herschel... Sir George Airy, the Astronomer Royal, is the admitted master of the sublime science. There are other eminent English astronomers-as John Hinde, the discoverer of many asteroids, and John Adams, also a Cambridge Senior Wrangler and the rival of Urban Leverrier, who groped his way by mathematical calculation to the discovery of the hitherto unknown planet Neptune. If incidents as brilliant and remarkable as these are wanting in the history of Sir George Airy, his claims to respect are equally valuable, solid, and enduring.
