After return arqujmedes his native land, Arquimeded made numberless investigations and discoveries in the areas of Mathematics, Mechanics and Hydrostatics detaching them to the arenqrio of your principally like inventing and mathematical life. And it is clear that they who hold this view, if they imagined a mass made up of sand in other respects as large as the mass of the Earth, including in it all the seas and the hollows of the Earth filled up to a height equal to that of the highest of the mountains, would be many times further still from recognizing that any number could be expressed which exceeded the multitude of the sand so taken.

Archimedes’ 10 63 grains of sand contain roughly 10 80 nucleons, making the two numbers relatively equal. But I will try to show you by arenaril of geometrical proofs, which you will be able to follow, that, of the numbers named by me and given in the work which I sent to Zeuxippus, some exceed not only the number of the mass of sand equal in magnitude to the Earth filled up in the way described, but also that of the mass equal in magnitude to the universe. His [Aristarchus’] hypotheses are that the fixed stars and the Sun remain unmoved, that the Earth revolves about the Sun on the circumference of a circle, the Sun lying in the middle of the orbit, and that the sphere of fixed stars, situated about the same center as the Sun, is so great that the circle in which he supposes the Earth to revolve bears such a proportion to the distance adquimedes the fixed stars as the center of the sphere bears to its surface.

The total number of nucleons in the observable universe of roughly the Hubble radius is the Eddington numbercurrently estimated xrquimedes 10 The work was originally thought to be lost, but was rediscovered in the celebrated Archimedes Palimpsest.
In order to do this, he had to estimate the size arenari the universe according to the contemporary model, and invent a way to talk about extremely large numbers.
Arquímedes by Hiara Saavedra on Prezi
The cube of 10, is a trillion 10 12 ; and multiplying a billion the number of grains of sand in a dactyl-sphere by a trillion number of dactyl-spheres in a stadium-sphere yields 10 21the number of grains of sand in a stadium-sphere. He then claimed without evidence that each poppy seed could contain a myriad 10, grains of sand.
It originally was a 10th century copy of an otherwise unknown work of the ancient mathematician, physicist, and engineer Archimedes c. A Greek stadium had a length of Greek feet, and each foot was 16 dactyls long, so there were 9, dactyls in a stadium.

One experiment was to estimate the angular size of the Sun, as seen from the Earth. In order to obtain an upper bound, Archimedes made the following assumptions of their dimensions:.
