- Archimedes was a mathematician who lived in Syracuse on the island of Sicily. His father, Phidias, was an astronomer, so Archimedes continued in th...
- Archimedes found that the volume of a sphere is two-thirds the volume of a cylinder that encloses it. He also discovered a law of buoyancy, Archime...
- Archimedes wrote nine treatises that survive. In On the Sphere and Cylinder, he showed that the surface area of a sphere with radius r is 4πr2 and...
- Almost nothing is known about Archimedes’ family other than that his father, Phidias, was an astronomer. The Greek historian Plutarch wrote that Ar...
- Archimedes was born about 287 BCE in Syracuse on the island of Sicily. He died in that same city when the Romans captured it following a siege that...
10. Mai 2024 · Das Siebeneck nach Archimedes (auch bekannt als Siebeneck im Kreise) bezeichnet das Konstruktionsverfahren von Archimedes für ein regelmäßiges Siebeneck. Es ist allerdings – wie jedes regelmäßige Siebeneck – nicht allein mit den klassischen Hilfsmitteln Zirkel und (unmarkiertem) Lineal exakt darstellbar.
Vor 5 Tagen · Der kanadische Teenager Brenden Sener hat ein beeindruckendes Wissenschaftsprojekt durchgeführt, bei dem er die Machbarkeit des legendären „ Todesstrahls “ von Archimedes untersuchte. Der antike griechische Erfinder Archimedes soll während der Belagerung von Syrakus römische Schiffe durch reflektiertes Sonnenlicht und Spiegel in Brand ...
25. Mai 2024 · Archimedes’ principle, physical law of buoyancy, discovered by the ancient Greek mathematician and inventor Archimedes, stating that any body completely or partially submerged in a fluid ( gas or liquid) at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid displaced by the body.

- A body at rest in a fluid is acted upon by a force pushing upward called the buoyant force, which is equal to the weight of the fluid that the body...
- Archimedes’ principle is very useful for calculating the volume of an object that does not have a regular shape. The oddly shaped object can be sub...
- The buoyancy force (B) is equal to the weight (W) of the fluid that a body in that fluid displaces. The weight W can be written in terms of the den...
26. Mai 2024 · May 26, 2024. Across the annals of history, few inventions have stood the test of time quite like the ingenious device we know as the Archimedes screw. A marvel of engineering, this simple machine, consisting of little more than a spiral inside a hollow tube, has been used for centuries to transport water from low-lying bodies to higher elevations.
