Vacuum Cleaner

-
.
Vacuum Cleaner, electrical appliance in common use for cleaning furniture, floors, rugs, and carpets by suction. Generally, vacuum cleaners are of two types: the vertical type, which is light and moves over the surfaces to be cleaned, and the canister, or tank, type, which trails a long hose with a nozzle that can be moved over the area to be cleaned. An electric motor inside the appliance turns a fan that creates a partial vacuum and causes outside air to rush into the evacuated space. This forces any dirt or dust near the nozzle into a bag inside the machine or attached to the outside.

Most vacuum cleaners have a variety of attachments that can be used to clean different types of surfaces, such as window sills and thick rugs and carpets; some are also equipped to polish floors and shampoo rugs. A reversible motor on many appliances is used to blow dirt out of difficult and inaccessible surfaces and also to spray paint.

Brahe, Tycho

Brahe, Tycho (1546-1601), Danish astronomer, who made precise, comprehensive astronomical measurements of the solar system and more than 700 stars . The data Brahe accumulated was superior to all other astronomical measurements made until the invention of the telescope in the early 17th century. Brahe was born in Knudstrup in southern Sweden (then part of Denmark). He studied law and philosophy at the universities of Copenhagen and Leipzig; at night, however, Brahe busied himself with observing the stars. With no instruments other than a globe and a pair of compasses, he succeeded in detecting grave errors in the standard astronomical tables, and set about correcting them. In 1572 he discovered a supernova in the constellation Cassiopeia . After Brahe had spent some time traveling and lecturing, Frederick II, king of Denmark and Norway, offered to provide Brahe with funds to construct and equip an astronomical observatory on the island of Hven (now Ven). Brahe accepted the proposal,

A stamp depicting the image of Hanaoka Seishu. Hanaoka Seishu (1760-1835), Japanese physician and pioneer of anesthetic surgery. Hanaoka studied traditional Sino-Japanese medicine, as well as what was then known about Western surgery in Japan. For over two decades he experimented with various drugs. Ultimately he created mafutsusan, an anesthetic compound made from six traditional plant-based drugs, including the alkaloids aconite (from the monkshood plant) and datura (from jimsonweed ). In 1805, using mafutsusan as an anesthetic, Hanaoka removed a tumor during breast cancer surgery. This was the world's first recorded successful surgical operation with anesthesia. Later, Hanaoka used the drug for other surgical operations, developing techniques for bladder stone removal and for amputation. Hanaoka attracted many students, and his surgical techniques became known as the Hanaoka method.

Bunsen, Robert Wilhelm

. Bunsen, Robert Wilhelm (1811-1899), German chemist, who, with the German physicist Gustav Robert Kirchhoff, invented the spectroscope and discovered spectrum analysis, which led to their joint discovery of the elements cesium and rubidium . Bunsen was born in Göttingen on March 31, 1811, and was educated at the University of Göttingen. Between 1836 and 1852 he taught successively at the Polytechnic Institute in Kassel and at the universities of Marburg and Breslau; thereafter he was professor at the University of Heidelberg until his retirement in 1889. Considered one of the greatest chemists in the world, Bunsen discovered (1834) the antidote that is still used today for arsenic poisoning: hydrated iron oxide. His research on the double cyanides confirmed the principle in organic chemistry that the nature of a compound depends on the radicals composing it. Contrary to popular belief, he had little to do with the invention of the Bunsen burner , a gas burner used in scientific lab
