Famous Astronomy Quotes

You can not drop astronomy. To get through this semester, I must live vicariously through you and hear about Cam at least three days a week." "I'm not going to drop the class-" Even though I sort of wanted to. "-But I doubt I'm going to have anything to tell you. It's not like we're even going to talk again." Jacob let go of my arm and sat back, eyeing me. "Famous last words, Avery.

Astronomy was full of such intriguing but meaningless coincidences. The most famous was the fact that, from the Earth, both Sun and Moon have the same apparent diameter.

In the year 1456 ... a Comet was seen passing Retrograde between the Earth and the sun... Hence I dare venture to foretell, that it will return again in the year 1758.

There it was that I found and visited the famous Galileo, grown old, a prisoner to the Inquisition, for thinking in astronomy otherwise than the Franciscan and Dominican licensers thought. And though I knew that England then was groaning loudest under the prelatical yoke, nevertheless I took it as a pledge of future happiness, that other nations were so persuaded of her liberty. Yet was it beyond my hope that those worthies were then breathing in her air, who should be her leaders to such a deliverance, as shall never be forgotten by any revolution of time that this world hath to finish.

For almost all astronomical objects, gravitation dominates, and they have the same unexpected behavior. Gravitation reverses the usual relation between energy and temperature. In the domain of astronomy, when heat flows from hotter to cooler objects, the hot objects get hotter and the cool objects get cooler. As a result, temperature differences in the astronomical universe tend to increase rather than decrease as time goes on. There is no final state of uniform temperature, and there is no heat death. Gravitation gives us a universe hospitable to life. Information and order can continue to grow for billions of years in the future, as they have evidently grown in the past. The vision of the future as an infinite playground, with an unending sequence of mysteries to be understood by an unending sequence of players exploring an unending supply of information, is a glorious vision for scientists. Scientists find the vision attractive, since it gives them a purpose for their existence and an unending supply of jobs. The vision is less attractive to artists and writers and ordinary people. Ordinary people are more interested in friends and family than in science. Ordinary people may not welcome a future spent swimming in an unending flood of information. A darker view of the information-dominated universe was described in the famous story “The Library of Babel,” written by Jorge Luis Borges in 1941.§ Borges imagined his library, with an infinite array of books and shelves and mirrors, as a metaphor for the universe. Gleick’s book has an epilogue entitled “The Return of Meaning,” expressing the concerns of people who feel alienated from the prevailing scientific culture. The enormous success of information theory came from Shannon’s decision to separate information from meaning. His central dogma, “Meaning is irrelevant,” declared that information could be handled with greater freedom if it was treated as a mathematical abstraction independent of meaning. The consequence of this freedom is the flood of information in which we are drowning. The immense size of modern databases gives us a feeling of meaninglessness. Information in such quantities reminds us of Borges’s library extending infinitely in all directions. It is our task as humans to bring meaning back into this wasteland. As finite creatures who think and feel, we can create islands of meaning in the sea of information. Gleick ends his book with Borges’s image of the human condition: We walk the corridors, searching the shelves and rearranging them, looking for lines of meaning amid leagues of cacophony and incoherence, reading the history of the past and of the future, collecting our thoughts and collecting the thoughts of others, and every so often glimpsing mirrors, in which we may recognize creatures of the information.

Astronomy was the special science of the Babylonians, for which they were famous throughout the ancient world.

The Historical Setting of Genesis Mesopotamia: Sumer Through Old Babylonia Sumerians. It is not possible at this time to put Ge 1–11 into a specific place in the historical record. Our history of the ancient Near East begins in earnest after writing has been invented, and the earliest civilization known to us in the historical record is that of the Sumerians. This culture dominated southern Mesopotamia for over 500 years during the first half of the third millennium BC (2900–2350 BC), known as the Early Dynastic Period. The Sumerians have become known through the excavation of several of their principal cities, which include Eridu, Uruk and Ur. The Sumerians are credited with many of the important developments in civilization, including the foundations of mathematics, astronomy, law and medicine. Urbanization is also first witnessed among the Sumerians. By the time of Abraham, the Sumerians no longer dominate the ancient Near East politically, but their culture continues to influence the region. Other cultures replace them in the political arena but benefit from the advances they made. Dynasty of Akkad. In the middle of the twenty-fourth century BC, the Sumerian culture was overrun by the formation of an empire under the kingship of Sargon I, who established his capital at Akkad. He ruled all of southern Mesopotamia and ranged eastward into Elam and northwest to the Mediterranean on campaigns of a military and economic nature. The empire lasted for almost 150 years before being apparently overthrown by the Gutians (a barbaric people from the Zagros Mountains east of the Tigris), though other factors, including internal dissent, may have contributed to the downfall. Ur III. Of the next century little is known as more than 20 Gutian kings succeeded one another. Just before 2100 BC, the city of Ur took control of southern Mesopotamia under the kingship of Ur-Nammu, and for the next century there was a Sumerian renaissance in what has been called the Ur III period. It is difficult to ascertain the limits of territorial control of the Ur III kings, though the territory does not seem to have been as extensive as that of the dynasty of Akkad. Under Ur-Nammu’s son Shulgi, the region enjoyed almost a half century of peace. Decline and fall came late in the twenty-first century BC through the infiltration of the Amorites and the increased aggression of the Elamites to the east. The Elamites finally overthrew the city. It is against this backdrop of history that the OT patriarchs emerge. Some have pictured Abraham as leaving the sophisticated Ur that was the center of the powerful Ur III period to settle in the unknown wilderness of Canaan, but that involves both chronological and geographic speculation. By the highest chronology (i.e., the earliest dates attributed to him), Abraham probably would have traveled from Ur to Harran during the reign of Ur-Nammu, but many scholars are inclined to place Abraham in the later Isin-Larsa period or even the Old Babylonian period. From a geographic standpoint it is difficult to be sure that the Ur mentioned in the Bible is the famous city in southern Mesopotamia (see note on 11:28). All this makes it impossible to give a precise background of Abraham. The Ur III period ended in southern Mesopotamia as the last king of Ur, Ibbi-Sin, lost the support of one city after another and was finally overthrown by the Elamites, who lived just east of the Tigris. In the ensuing two centuries (c. 2000–1800 BC), power was again returned to city-states that controlled more local areas. Isin, Larsa, Eshnunna, Lagash, Mari, Assur and Babylon all served as major political centers.

One nice touch about Christy’s discovery was that it happened in Flagstaff, for it was there in 1930 that Pluto had been found in the first place. That seminal event in astronomy was largely to the credit of the astronomer Perdval Lowell. Lowell, who came from one of the oldest and wealthiest Boston families (the one in the famous ditty about Boston being the home of the bean and the cod, where Lowells spoke only to Cabots, while Cabots spoke only to God), endowed the famous observatory that bears his name, but is most indelibly remembered for his belief that Mars was covered with canals built by industrious Martians for purposes of conveying water from polar regions to the dry but productive lands nearer the equator. Lowell’s other abiding conviction was that there existed, somewhere out beyond Neptune, an undiscovered ninth planet dubbed, Planet X. Lowell based this belief on irregularities he detected in the orbits of Uranus and Neptune, and devoted the last years of his life to trying to find the gassy giant he was certain was out there. Unfortunately, he died suddenly in 1916, at least partly exhausted by his quest and the search fell into abeyance while Lowell’s heirs squabbled over his estate. However, in 1929, partly as a way of deflecting attention away from the Mars canal saga (which by now had become a serious embarrassment), the Lowell Observatory directors decided to resume the search and to that end hired a young man from Kansas named Clyde Tombaugh. Tombaugh had no formal training as an astronomer, but he was diligent and he was astute, and after a year’s patient searching he somehow spotted Pluto, a faint point of light in a glittery firmament. It was a miraculous find, and what made it all the more striking was that the observations on which Lowell had predicted the existence of a planet beyond Neptune proved to be comprehensively erroneous. Tombaugh could see at once that the new planet was nothing like the massive gasball Lowell had postulated, but any reservations he or anyone else had about the character of the new planet were soon swept aside in the delirium that attended almost any big news story in that easily excited age. This was the first American-discovered planet and no one was going to be distracted by the thought that it was really just a distant icy dot. It was named Pluto at least partly because the first two letters made a monogram from Lowell’s initials. Lowell was posthumously hailed everywhere as a genius of the first order, and Tombaugh was largely forgotten, except among planetary astronomers, who tend to revere him.
