Just How Small Is an Atom? - Jonathan Bergmann Whether we’re zooming in to the wavelength of a gamma ray or zooming out to the size of a galaxy, it can be difficult to wrap our heads around the big numbers we’re measuring—like nanometers (10-9meters) or gigameters (109). Take a look at these efforts to represent big numbers. What are the strengths of each? How would you represent a large number (like a gigameter)?

Archimedes Archimedes, as an artist thinks he was. Archimedes (287 BC–212 BC)[1] was a Greek scientist. He was an inventor, an astronomer, and a mathematician. He was born in the town of Syracuse in Sicily. His father was Phidias, an astronomer, and he may have been in the family of a king of Syracuse. Spherical geometry[change | change source] On the Sphere and Cylinder is a work that was published by Archimedes in two volumes in about 225 BC.[2] On the sphere, he showed that the surface area is four times the area of its great circle. The surface area of a cylinder is equal to: The volume of the cylinder is: A sculpted sphere and cylinder were placed on the tomb of Archimedes at his request. Archimedes the scientist[change | change source] Archimedes is also well known for being the first person to understand statics, which is a part of applied mathematics. Archimedes may have used his principle of buoyancy to determine whether the golden crown was less dense than solid gold.

Archimedes is considered to be one of the most brilliant mathematicians in history. Legend has it that the king worried that the royal crown maker might be replacing some of the gold in his crowns with a less valuable material. Archimedes thought of the solution about finding gold purity while in bath tub. King Hiero called upon Archimedes to design war machines to defend the country against the Romans who were intent on invading.
