Albert Einstein worked in the fields of mathematics and physics, and most of his contributions were in terms of academic theory. There is, however, a refrigerator that bears his name, and he had also developed a compass, a gyrocompass and a hearing aid.Know More
Albert Einstein is primarily known for contributing the theory of relativity as well as major contributions to the fields of statistical and quantum mechanics. The theory of relativity extended the existing equations by Maxwell to the laws of mechanics and explained how objects move through time and space. His contribution to quantum mechanics was to describe light according to Max Planck's quantum hypothesis, and his contribution to statistical mechanics was an experiment that supported the existence of molecules equivalent in size to the atom.
Einstein developed the Einstein refrigerator with Leo Szilard in 1926. It was created in response to news reports of a family who had died when their refrigerator seal developed a leak and toxic fumes filled their home. Einstein's refrigerator eliminated the possibility of seal failure by having no moving parts whatsoever. The refrigerator was an absorption model that required a heat source, which was common for the time, but was unique in using loops of ammonia and water for the cooling action. Though the refrigerator bears his name, it is unclear how much of it Einstein actually developed.Learn more about Inventions
The Ancient Egyptians are the well-known constructors of the Pyramids and the Great Sphinx. They invented hieroglyphs, one of the earliest writing systems, and a number system for whole numbers and fractions, including rudimentary algebraic formulations. Egyptians created breath mints, toothpaste, the calendar and bowling. Perhaps their greatest invention, however, was papyrus scrolls, which allowed information to be collected, transported and stored for immediate use or for future generations.Full Answer >
Prior to publishing his groundbreaking papers on special relativity and the photoelectric effect in 1905, Albert Einstein worked intermittently as a tutor and as a clerk in the Swiss government's patent office. As an assistant examiner at Switzerland's Federal Office for Intellectual Property, Einstein worked to evaluate patent applications relating to the registration of electromagnetic device inventions.Full Answer >
Although Albert Einstein's theories laid the foundation for the creation of the atomic bomb, the only thing he really invented was a refrigerator. Invented in 1926 in conjunction with his former student Leo Szilard, the Einstein refrigerator did not require anything but a heat source for operation — it didn't even need electricity — and he received a patent for it.Full Answer >
Regarded as one of the greatest mathematicians of all time, Archimedes invented a method known as Archimedes’ principle. It is a method used for determining the volume of an asymmetrical object. Archimedes of Syracuse was a mathematician, inventor and engineer from Ancient Greece.Full Answer >
