He was said that he died in the Eighty Years’ War in the Netherlands. His mother Katharina Guldenmann was a healer and herbalist who tried for witchcraft. At six years old Kepler witnessed the Great Comet of 1577. In 1589 he went to the University of Tübingen where he studied mathematics. Johannes Kepler was forced to leave his teaching post at Graz due to the Counter Reformation because he was Lutheran and moved to Prague to work with the renowned Danish astronomer, Tycho Brahe.
His Work * First major work: Mysterium Cosmographicum- published as a defence for the Copernican system. This was in Graz, and there he had an epiphany and eventually managed to figure out the relative size of each planets (only 6 known at that time) orbit path, while also finding a formula relating the size of a planet to its orbit time, but he rejected it later as he believed it was not precise enough. * He was the first person to investigate the formation of pictures with a pinhole camera * First to correctly explain planetary motion * Became founder of celestial mechanics * First to explain process of vision by refraction, and the use of both eyes for depth perception * First to formulate glasses for near-sightedness and farsightedness * First to explain principles of how a telescope worked Planetary Motion * Task set be another famous
Throughout the 1800s, attempts were made to detect the ether or its movement directly, culminating in the famous Michelson-Morley experiment. They all failed to actually detect the ether, resulting in a huge debate as the twentieth century began. Was light a wave or a particle? In 1905, Albert Einstein published his paper to explain the photoelectric effect, which proposed that light traveled as discrete bundles of
First was to “…serve as a solar and lunar observatory for calendrical purposes, to legitimate priestly power (especially by predicting eclipses), and to advance intellectual curiosity about heavens,” (Ray 241). This theory has since been disproved, as he overestimated the number of solar and lunar alignments. There have,
His manuscript included the equation now named for the scientist. Tsiolkovsky's formula provides the mathematical relationship between the changing mass of a rocket as it burns through fuel, the velocity of the exhaust gases, and the final speed of the rocket. It is considered a foundation of astronautics. But though Tsiolkovsky was the first to delve into such complex problems, his role as a provincial schoolteacher, combined with the shutdown of the magazine, meant that very few copies of his research left Russia. In the 1920s, German scientist Hermann Oberthand American physicist Robert Goddard were independently
The Dutch astronomer Jan Hendrik Oort (1900-1992) overturned the idea that our sun is at the center of the Milky Way galaxy. He contributed greatly to knowledge about the structure and evolution of our galaxy, and also discovered the place of origin of most comets, the Oort Cloud. Jan Oort was born on April 28, 1900, in the farming village of Franeker in Holland. At the age of 17 he entered the University of Groningen and earned his doctoral degree in 1926. He received the Bachiene Foundation Prize (1920), undertook research at the Leiden Observatory (1924), and lived abroad as a research associate at the Yale University Observatory (1924-1926).
Today, we know that stars are born from interstellar gas clouds, shine by nuclear fusion and then die, sometimes in dramatic ways. This paper will discuss the life cycle of stars, but to have a better understanding of the life cycle of stars we first need to understand their birth. Since we were children, we have been curious about those little lights in the night sky that seem to twinkle in the darkness. We even sang about them growing up, “Twinkle, twinkle, little star, how I wonder what you are? As a child, we could not understand the magnificent miracle that takes place for a star to be born.
Telescopes helped discover many new planets and asteroids which ultimately led to the theory of the speed of light, Telescopes have helped astronomers understand gravity and its role on the Earth (Mason, 2008). With further viewing from the telescope it also showed us that light here on earth radiates from our Sun and all the other stars in our universe. Had we not have had the telescopes we would still be very behind on research of all the planets which are not accessible by any human or machine to this day. In the very early ages of human life the earth and world was viewed much differently mainly ruled by religion and the views of religion. People were less educated and much easier to be controlled.
Konstantin Tsiolkovsky is a Soviet scientist. He prophesies “Earth is the cradle of human reason, but it’s impossible to live for ever in one’s cradle.” Konstantin Tsiolkovsky caught a serious illness and became hard to hear when he was very young. This made him had to study at home by himself. He then went to Moscow for 3 years and studied Advanced Mathematics, University courses by himself. His space flight idea was came up at that time.
Fleming discovered the Horsehead nebula on Harvard plate B2312, describing the bright nebula (later known as IC-434) as having "a semicircular indentation 5 minutes in diameter 30 minutes south of Zeta [Orionis]." William Pickering, who took the photograph, speculated that the spot was dark obscuring matter. All subsequent articles and books seem to deny Fleming and W. H. Pickering credit because the compiler of the first Index Catalogue, J. L. E. Dreyer[->5], eliminated Mrs. Fleming's name from the list of objects then discovered by Harvard, attributing them all instead merely to "Pickering". However, by the release of the second Index Catalogue by Dreyer in 1908, Mrs. Fleming and others at Harvard were famous enough to receive proper credit. Fleming was placed in charge of dozens of women hired to do mathematical classifications and edited the observatory's publications.
