According to teach-nology.com, geometry is used in astronomy to determine the properties of stars and other objects in space. It is developed to be a practical guide in measuring the velocity, area, volume and length of heavenly bodies. Astronomy is the study of these objects, and geometry assists in figuring out their scope and placement in the firmament.Continue Reading
According to Encyclopaedia Britannica, Greek astronomers used geometry by supposing that the planets, the moon and the sun moved around a stationary earth in a set of circles. To achieve this, they calculated the speed of these circles from points of observed motion.
Geometry in nature is found practically everywhere, states Wonder Whizkids, from the proportions of the human body to the shape of a shell. In the early days, the focus of geometry seemed to be on solids and shapes, before it slowly moved to the properties of objects and the relationship between shapes and solids.
Today, geometry is much more about reasoning and analysis. Geometry has a lot of practical uses in real life, as well, says teach-nology.com. For example, it can be a huge factor in how a person goes about his daily business. For instance, a person turning while driving is unconsciously using geometry to calculate the radius of the turn. It is also much used in industry, such as when planning construction projects.Learn more about Astronomy
Math is used in astronomy to calculate routes for satellites, rockets and space probes. In addition, math is used in the global positioning system, for transmitting messages when data is compressed, and for coding the images and element modeling to build spacecraft.Full Answer >
Galileo's main impact on the world was his improvement upon the telescope and being the first to use it in the science of astronomy. He also supported the Copernican system that stated that planets orbit the sun rather than the Earth as the Catholic Church said at the time. His other contribution was to contradict Aristotle's teachings that heavier objects fall faster than lighter ones.Full Answer >
Radio telescopes are useful in astronomy because radio waves can be observed any time of the day or night. Radio waves are also not distorted by the Earth's atmosphere or by gas and dust.Full Answer >
