William Herschel

William Herschel (William Herschel), like his father and brothers, started living as a musician. When he was 15, he ran away to the UK in Hanover, Germany's home to avoid service during the seven year war. He began studying the importance of mathematics in music by making a living as a music teacher, composition and organist. From a mathematical point of view, one of the astronomers is that Herschel 's curiosity turned into astronomy, the appeal can change his life, he became the most famous of his era

By borrowing the Herschel telescope began his career. As he began to make himself, poor quality, all of his leisure time is spent outside his music career to improve his design. Sister Caroline, accompanied him at home to help with housework or housework, accompanies him to complete the work to eventually become a famous astronomer. William sits on the observing telescope, and his results known as Caroline, he is recorded: they cooperate. Caroline will eventually become an observer

Herschel brought his reputation and wealth, which found Uranus in 1781. He was elected "king's astronomer" and pension recipient. To use this full-time position astronomy - a very few people today know or playing - Herschel immediately gave up on his music activities and composition. Caroline also obtains the "king of assistant astronomers" of the pension.

Herschel will find out the correct theory of the infrared region, and the disc-like galaxy to identify the movement of the sun found nearly in a binary, the universe. He and his son John Herschel cataloged on 4,600 nebulae. Named after his name Crater of the moon and Saturn, Mimasu moon today Today

These have nothing to do with the actual planet, but they are named by astronomer William Herschel in the late 1700's because they look like a round object blur like a bit solar system planet at his telescope It was. - After more than two centuries, research by the same name by William Herschel planetary nebula, HSO (Herschel Space Telescope) produces amazing discoveries. A star like a sun burning hydrogen with its stable core in billions of years of time. When the fuel was spent, the central star was deployed to a red giant star. However, it becomes unstable and falls to form the outer planetary nebula. The rest of the core's core eventually became a UV white hot dwarf in the surroundings

In the early 19th century, we discovered the wavelength of electromagnetic radiation other than visible light. Infrared was discovered by astronomer William Herschel. In 1800 Herschel published his findings in front of the Royal Society in London. The temperature detected by refracting the light from the sun, such as Herschel and Ritter Prism, by recording an infrared thermometer increased (beyond the red part of the spectrum). In 1801, German physicist Johann Wilhelm Ritter (Johann Wilhelm Ritter) pointed out that ultraviolet light, he points out that the light of the silver chloride formulation prism is darker than purple It was. In Ritter's experiment, it is to become a pioneer of photography. Ritter pointed out that UV may cause a chemical reaction

Since light outside the visible range was found and described by William Herschel (Infrared) and Johann Wilhelm Ritter (UV), Thomas Young, Thomas Seebek et al., The concept of the visible spectrum is clearer in the early 19th century It becomes. In 1802, Yang was the first to measure the wavelength of people's different color light. Many species can see light of frequencies other than the "visible spectrum" of humanity. Bees and many other insects can detect ultraviolet light they can find honey in flowers. Because there are plant species, it depends on insect pollination of its appearance, with ultraviolet light, you can gain breeding success, their diversity without human nature. Birds can see ultraviolet visible marks, ultraviolet light (300-400 nm) only the feathers of some birds of sex. However, many animals can see the ultraviolet range is not visible other red or red wavelengths
