Circumference Of The Earth Quotes & Sayings

Eratosthenes's only tools were sticks, eyes, feet, and brains; plus a zest for experiment. With those tools he correctly deduced the circumference of the Earth, to high precision, with an error of only a few percent. That's pretty good figuring for 2200 years ago. — Carl Sagan

The Age of Intellect is accompanied by surprising advances in natural science. In the ninth century, for example, in the age of Mamun, the Arabs measured the circumference of the earth with remarkable accuracy. Seven centuries were to pass before Western Europe discovered that the world was not flat. Less than fifty years after the amazing scientific discoveries under Mamun, the Arab Empire collapsed. Wonderful and beneficent as was the progress of science, it did not save the empire from chaos. — John Bagot Glubb

Remembering ... that Eratosthenes of Cyrene, employing mathematical theories and geometrical methods, discovered from the course of the sun, the shadows cast by an equinoctial gnomon, and the inclination of the heaven that the circumference of the earth is two hundred and fifty-two thousand stadia, that is, thirty-one million five hundred thousand paces. — Marcus Vitruvius Pollio

WhhheeeEEEEEEEEEEEEEEE! The scream of jet engines rises to a crescendo on the runways of the world. Every second, somewhere or other, a plane touches down, with a puff of smoke from scorched tyre rubber, or rises in the air, leaving a smear of black fumes dissolving in its wake. From space, the earth might look to a fanciful eye like a huge carousel, with planes instead of horses spinning round its circumference, up and down, up and down. Whhheeeeeeeeeee! — David Lodge

As Joanna Macy reminds us, "Information by itself can increase resistance [to engagement], deepening the sense of apathy and powerlessness." Stories about particular individuals and specific situations usually have the opposite effect. By giving unwieldy problems a human face, they also bring them down to a human-and thus manageable-scale. — Paul Rogat Loeb

It was in Alexandria that the circumference of the earth was first measured, the sun fixed at the center of the solar system, the workings of the brain and the pulse illuminated, the foundations of anatomy and physiology established, the definitive editions of Homer produced. It was in Alexandria that Euclid had codified geometry. — Stacy Schiff

If you have a steel ball, solid steel, the size of this earth, 25,000 miles in circumference, and every one million years a little sparrow would be released to land on that ball to sharpen his beak and fly away only to come back another million years later and begin again, by the time he would have worn that ball down to the size of a BB, eternity would have just begun. — David Jeremiah

Let us begin with some of the earliest discoveries and correct hypotheses. Anaximander thought that the earth floats freely, and is not supported on anything. Aristotle,2 who often rejected the best hypotheses of his time, objected to the theory of Anaximander, that the earth, being at the centre, remained immovable because there was no reason for moving in one direction rather than another. If this were valid, he said, a man placed at the centre of a circle with food at various points of the circumference would starve to death for lack of reason to choose one portion of food rather than another. This argument reappears in scholastic philosophy, not in connection with astronomy, but with free will. It reappears in the form of 'Buridan's ass', which was unable to choose between two bundles of hay placed at equal distances to right and left, and therefore died of hunger. — Anonymous

About the fearful sphere which we inhabit, whose centre may be calculated and whose circumference is physically established, there spin metaphors whose centre is everywhere and whose circumference shows itself only through holes in the dark. — Michael Ayrton

It's extreme. The character comes back from the dead, and, at first he doesn't know where he is, how he got there ... How does that tie in with the physicality? I just didn't think he should be too healthy-looking, so I lost some weight for the role. — Brandon Lee

I walk alone in the darkness and wonder how a person would begin to determine the circumference of the earth. I have no idea. I'd probably just google it. — Robin Sloan

For the observed difference in the shadow lengths, the distance between Alexandria and Syene had to be about seven degrees along the surface of the Earth; that is, if you imagine the sticks extending down to the center of the Earth, they would there intersect at an angle of seven degrees. Seven degrees is something like one-fiftieth of three hundred and sixty degrees, the full circumference of the Earth. Eratosthenes knew that the distance between Alexandria and Syene was approximately 800 kilometers, because he hired a man to pace it out. Eight hundred kilometers times 50 is 40,000 kilometers: so that must be the circumference of the Earth. — Carl Sagan

A circle is the only geometric shape defined by its centre. No chicken and egg about it, the centre came first, the circumference follows. The earth, by definition, has a centre. And only the fool that knows it can go wherever he pleases, knowing the centre will hold him down, stop him flying out of orbit. But when your sense of centre shifts, comes whizzing to the surface, the balance has gone. The balance has gone. The balance my baby has gone. — Sarah Kane

The lack of stringent laws and the inefficient prosecution of
perpetrators have made it increasingly difficult for victims and their
families to get the justice they deserve. — Oche Otorkpa

There are no coincidences. Just miracles by the boatload. — Clare Vanderpool

My ideal is to wake up in the morning and run around the meadow naked. — Daryl Hannah

Columbus therefore cheated on his calculations, as the examining faculty of the University of Salamanca quite correctly pointed out. He used the smallest possible circumference of the Earth and the greatest eastward extension of Asia he could find in all the books available to him, and then exaggerated even those. Had the Americas not been in the way, Columbus' expeditions would have failed utterly. — Carl Sagan

Let man then contemplate the whole of nature in her full and grand majesty, and turn his vision from the low objects which surround him. Let him gaze on that brilliant light, set like an eternal lamp to illumine the universe; let the earth appear to him a point in comparison with the vast circle described by the sun; and let him wonder at the fact that this vast circle is itself but a very fine point in comparison with that described by the stars in their revolution round the firmament. But if our view be arrested there, let our imagination pass beyond; it will sooner exhaust the power of conception than nature that of supplying material for conception. The whole visible world is only an imperceptible atom in the ample bosom of nature. It is an infinite sphere, the center of which is everywhere, the circumference nowhere. In short it is the greatest sensible mark of the almighty power of God, that imagination loses itself in that thought. — Blaise Pascal

Today Eratosthenes' method [of calculating the circumference of the earth] seems almost banal ... yet it is inaccessible to prescientific civilizations, and in all of Antiquity not a single Latin author succeeded in stating it coherently. — Lucio Russo

The reason why the Great Pyramid of Giza has Earth's circumference figure embedded in it is not because ancient Egyptians knew that number, but because they were observing the horizon and the lunar movement. — Ibrahim Ibrahim

The perfume that her body exhaled was of the quality of that earth-flesh, fungi, which smells of captured dampness and yet is so dry, overcast with the odour of oil of amber, which is an inner malady of the sea, making her seem as if she had invaded a sleep incautious and entire. Her flesh was the texture of plant life, and beneath it one sensed a frame, broad, porous and sleep-worn, as if sleep were a decay fishing her beneath the visible surface. About her head there was an effulgence as of phosphorous glowing about the circumference of a body of water - as if her life lay through her in ungainly luminous deteriorations - the troubling structure of the born somnambule. — Djuna Barnes

The two-point rhythm of walking's stride clears the mind for thinking. (N.B.: Perhaps, after telling the spinal circuits to "take a walk," the forebrain shifts to automatic pilot, so to speak, freeing the neocortex to ponder important issues of the day.) Many philosophers were lifetime walkers, who found that bipedal rhythms facilitated creative contemplation and thought. In his short life, e.g., Henry David Thoreau walked an estimated 250,000 miles--ten times the circumference of earth. — David B. Givens

You do realize that means you're officially off the market." I say, poking him in the hard stomach. The warm, wide palms of his hands cup my face and my breath hitches.
"Baby, I've been off the market since the moments these cheeks turned the sexiest shade of pink."
Heat flares under my skin and I avert my gaze. "And when was that?"
"When I caught you eye-fucking me."
I shove him and he lets go of my face. "I did not."
He laughs loudly and squeezes me against him. "You did. Admit it. — Skyla Madi

The physical heart, which houses the spiritual heart, beats about 100,000 times a day, pumping two gallons of blood per minute and over 100 gallons per hour. If one were to attempt to carry 100 gallons of water (whose density is lighter than blood) from one place to another, it would be an exhausting task. Yet the human heart does this every hour of every day for an entire lifetime without respite. The vascular system transporting life-giving blood is over 60,000 miles long - more than two times the circumference of the earth. So when we conceive of our blood being pumped throughout our bodies, know that this means that it travels through 60,000 miles of a closed vascular system that connects all the parts of the body - all the vital organs and living tissues - to this incredible heart. — Hamza Yusuf
