Mathematics and Astronomy

Astronomy, is for me, why we are even here at all. As humans [and wizards], we owe our lives to discovering our own universe and beyond, it is our utmost dedication that we discover facts and information on everything around us. People have dedicated months, years, to discovering what truly makes us part of the universe, we have achieved and advanced so much just by studying our stars, our solar system and our neighbouring planets.

Ancient Greek astronomers made some amazing mathematical and philosophical discovers about our universe. From the Hellenistic Greek observations in approximately 300 B.C.E., to the invention of the first telescope in the seventeenth century, to the launching of today’s space probes, one thing is evident: astrological observations are imperative to creating a calendar.

During the first millennium B.C. scientists realized that astronomy had to become more scientific. Middle Eastern and Chinese cultures started studying the Sun, stars and the planets more closely in an attempt to learn more about our position in the universe.. Star positions also became important tools in understanding directions, and helping with navigation. One philosopher stated in 434 B.C. that the Sun was a ball of fire 60 kilometres in diameter, hovering 6500 kilometres above Earth’s surface. Around 130 B.C., Ptolemy wrote Almagest, which was a huge collection of astronomical data which included mathematical models, information about eclipses, and planetary and stellar positions and movements. It remained a major go to book for astronomy for hundreds of years, and was not seriously challenged until Copernicus disputed the geocentric model of the solar system in the 1500’s

Among these people were Copernicus who believed the sun was at the center of the world and the earth, stars and planets revolved around it. Danish astronomer Brahe helped contribute to this idea by contributing a large mass of data about the universe that he was able to discover. His student Kepler kept his ideas going, as he formulated many laws of planetary motion. He said the orbits around the sun were elliptical, planets don’t move in a uniform speed and the time a planet completes its orbit is related to its distance from the sun. Meanwhile, Florentine Galileo decided to use experiments to find out what happened and not what should happen, and discovered that a uniform force makes a uniform acceleration as well as inertia laws, that an object will be in motion forever unless stopped by another force.

the heliocentric solar system. Johannes Kepler further modified the heliocentric system, by mathematically showing that the planets’ orbits are elliptical. With his invention of the telescope, Galileo made new observations about the solar system and found mathematical laws that described the movement of the planets. Later, Isaac Newton established a universal law of gravity. With the new scientific discoveries, the gap between religion and science increased. Science revolutionized the human though and its understanding of the universe.

Astronomy is probably the most ancient natural science in the history of the world. It is the study of celestial objects, such as planets, moons, stars, galaxies, and comets; in terms of mathematics, psychics, and chemistry. Earlier civilization studied astronomy by observations, whereas, now the focus is more on the physics and chemistry of the celestial bodies.

(between June 20th and June 22nd) the Greek Astronomer, Eratosthenes had heard of a famous well in a Egyptian City called Syene (now known as Aswan) located around the Nile River. He knew that every year on the solstice, there was no shadow on the bottom of well but instead the rays of sunlight reflected back, and not on the sides of the well as on other days. He came to a conclusion that the sun was directly overhead in Syene at noon every year. He knew that in his hometown Alexindra, the sun was never directly above him even on the solstice. He assembled a pole in Alexindra to study and calculate the shadows position eventually proving that no sun was directly above but faintly south. Knowing that the earth was curved and knowing the distance between the two cities, Syene and Alexandra he calculated the planets circumference by doing simple geometry. “Eratosthenes could measure the angle of the Sun’s rays off the vertical by dividing the length of the leg opposite the angle (the length of the shadow) by the leg adjacent to the angle (the height of the pole). This gave him an angle of 7.12 degrees. He knew that the circumference of Earth constituted a circle of 360 degrees, so 7.12 (or 7.2, to divide 360 evenly by 50) degrees would be about one-fiftieth of the circumference. He also knew the approximate distance between Alexandria and Syene, so he could set up this

Do you want to know more about the universe, but dont have the time to actually pursue a detailed study? Then Astrophysics for People in a Hurry is exactly the book for you. The book describes the origins of the universe, delves deep into how it functions, and discusses different concepts of physics. Tyson tries to explain these concepts in the most simplified manner with a lot of humor. He also leaves us with not just a better sense of understanding of the universe, but also many questions about how to relate with the infinite cosmos with our own human and limited understanding.

Prior to Galileo’s time, the Greek and medieval mind, science was a kind of formalism, a means of coordinating data, which had no bearing on the ultimate reality of things. The point was to give order to complicated data, and all that mattered was the hypothesis that was simplest to understand and most convenient. Astronomy and mathematics were regarded as the playthings of intellectuals. They were accounted as having neither philosophical nor theological relevance. There was genuine puzzlement among Churchmen that they had to get involved in a quarrel over planetary orbits.

The earliest calendar to keep track of the cycles of the celestial bodies was an Ancient Calendar known as the Egyptian calendar that was based on the moon's cycles and is thought to have been created in 4236 B.C.E. This is the way that Ancient civilizations determined the seasons, months, and years. Approximately, five thousand years ago the Sumerians in the Tigris-Euphrates valley had a calendar that divided the year into 30 day months, divided the day into 12 periods, and divided these periods into 30 parts. Subsequently, the earliest Egyptian calendar was based on the moon’s cycles, but soon the

Johannes Kepler was a German astronomer and mathematician who lived between 1671-1630. Kepler was a Copernican and initially believed that planets should follow perfectly circular orbits (“Johan Kepler” 1). During this time period, Ptolemy’s geocentric theory of the solar system was accepted. Ptolemy’s theory stated that Earth is at the center of the universe and stationary; closest to Earth is the Moon, and beyond it, expanding towards the outside, are Mercury, Venus, and the Sun in a straight line, followed by Mars, Jupiter, Saturn, and the “fixed stars”. The Ptolemaic system explained the numerous observed motions of the planets as having small spherical orbits called epicycles (“Astronomy” 2). Kepler is best known for introducing three

Mathematics, study of relationships among quantities, magnitudes, and properties and of logical operations by which unknown quantities, magnitudes, and properties may be deduced. In the past, mathematics was regarded as the science of quantity, whether of magnitudes, as in geometry, or of numbers, as in arithmetic, or of the generalization of these two fields, as in algebra. Toward the middle of the 19th century, however, mathematics came to be regarded increasingly as the science of relations, or as the science that draws necessary conclusions. This latter view encompasses mathematical or symbolic logic, the science of using symbols to provide an exact theory of logical deduction and inference based on

Since the first Egyptian farmers discovered the annual reappearance of Sirius just before dawn a few days before the yearly rising of the Nile, ancient civilizations around the Mediterranean have sought to explain the movements of the heavens as a sort of calendar to help guide them conduct earthly activities. Counting phases of the moon or observing the annual variations of day length could, after many years' collection of observations, serve as vital indicators for planting and harvesting times, safe or stormy season for sailing, or time to bring the flocks from winter to summer pastures. With our millennia of such observation behind us, we sometimes forget that seeing and recording anything less obvious than

Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, and astrological practices of pre-history: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy, and not completely disentangled from it until a few centuries ago in the Western World . In some cultures astronomical data was used for astrological prognostication.

Mathematics is the one of the most important subjects in our daily life and in most human activities the knowledge of mathematics is important. In the rapidly changing world and in the era of technology, mathematics plays an essential role. To understand the mechanized world and match with the newly developing information technology knowledge in mathematics is vital. Mathematics is the mother of all sciences. Without the knowledge of mathematics, nothing is possible in the world. The world cannot progress without mathematics. Mathematics fulfills most of the human needs related to diverse aspects of everyday life. Mathematics has been accepted as significant element of formal education from ancient period to the present day. Mathematics has a very important role in the classroom not only because of the relevance of the syllabus material, but because of the reasoning processes the student can develop.
