A flyswatter, usually consisting of a small rectangular sheet of flexible material, is a handheld device for smashing flies and other insects. The material is vented, thus reducing wind drag making it move faster in order to hit the target. The beginning flyswatters were just a striking surface attached to the end of a long stick. Dr. Samuel Crumbine was trying to raise awareness of the fly problem in Kansas in 1905 when he coined the term "swat the fly". Frank H. Rose created the "fly...
Lee De Forest invented the Audion, a forerunner of the triode, which is an amplifying vacuum tube. The grid controls the filament which sends the current from the filament. The Audion can detect radio signals by applying a small amount of power to the grid that can control a larger current from the filament plate. However, De Forest's Audion is distinct from the true vacuum triode since it is not capable of linear amplification. De Forest found that when gas was in a partial vacuum heated...
Count Alessandro Antonio Anastasio Volta was born on February 18, 1745 in Como, Duchy of Milan. At age 39, Volta became a professor at the Royal School in Como in the physics department. A year later, in 1775, Volta invented a device called the electrophorus which generates static electric charges. He marketed his creation so well, that he is often given credit as its inventor. However, a similar machine was documented by Johan Carl Wilcke in 1762. He changed his focus to chemistry in...
Lithium is the chemical element with symbol Li and atomic number 3. In the periodic table, it is located in group 1, among the alkali metals. Lithium in its pure form is a soft, silver white metal, that tarnishes and oxidizes very rapidly in air and water. It is the lightest solid element and is primarily used in heat transfer alloys, in batteries and serves as a component in some drugs known as mood stabilizers. Notable characteristics Lithium is the lightest metal and has a density...
