1572---Tycho Brahe (1546-1601) observes a "new star." (See also here.) \n\n1582---Pope Gregory the 13th reforms the calendar. \n  1588   The "Spanish Armada," a fleet attacking Britain, is destroyed by the British navy and by storms. For the first time Britain is able to claim part of the American continent. \n  Europe and Asia are introduced to American crops--potatoes, tomatoes, corn. Europe´s diet is also gradually enriched by sugar, oranges and pepper, originating in India. \n1609---Galileo Galilei (1564-1642) builds the first astronomical telescope and observes for the first time craters on the Moon, satellites around Jupiter, and the way Venus goes through phases like the Moon (crescent, etc.) .\n\n1610 (approx) Sunspots and their rotation with the Sun were discovered independently by Galileo Galilei, Johann Fabricius (Holland) and Christopher Scheiner.   All used the recently-invented telescope, and Scheiner apparently introduced the safe method of projecting the Sun's image on a flat surface.\n\n---Johann Kepler (1571-1630), using Tycho's observations, formulates his first two laws of planetary motion (3rd law in 1619). \n   After a failed attempt (1586) to establish a colony on Roanoke Island, Virginia (now part of N. Carolina), Jamestown is founded in Virginia in 1607, and the first English settlers land in Massachussetts Bay in 1620 (the "Pilgrims"). \n  1618-1648---The 30 years' war. A century after Martin Luther broke away from the Roman church, a great religious war sweeps Europe, devastates Germany and establishes Sweden as a major military power. In the civil war in England, parliament suspends monarchy 1645-1660, king beheaded 1649.

Astronomers define a coordinate system on the sky that lets them identify the relative positions of stars, planets, the Sun and other celestial phenomena (the coordinates are called "right ascension" and "declination", but we don't need to worry about that here). Because of their great distance from the Earth, the positions of most stars are fixed on the grid. The positions of the planets and the Sun, however, are seen to "travel" through the coordinate grid in systematic (though sometimes complicated) patterns. The paths of the planets was carefully observed by Tycho Brahe in the late 1500s. Following Brahe's death in 1601, Johannes Kepler used the data to develop a set of laws that govern the way the planets move around the Sun (he proposed them in 1609). These laws, (creatively) called Kepler's Laws, still hold today.\n\nWith Kepler's laws in hand, one can easily interpret the motion of the Sun through the coordinate grid described above as the result of the tilt of the Earth by 23.5 degrees with respect to the plane in which the Earth orbits the Sun. Since Kepler was the one to correctly interpret the motion of the planets and the Sun through the sky, he is the one that I would attribute the title "Discoverer of the 23.5 degree tilt", in the early 1600s.

Apollonius was known as 'The Great Geometer'. His works had a very great influence on the development of mathematics and his famous book Conics introduced the terms parabola, ellipse and hyperbola.\nMore information on the site:\nhttp://www.gap-system.org/~history/Mathematicians/Apollonius.html

He was the first to come up with a good system of classifying all life on earth. His system, with variations, is still in wide use today. \n\nVery Important Person to scientists!

This is pasage of biblography of my project\n\nGregor Mendel (1822-1884)\nSeung Yon Rhee \n--------------------------------------------------------------------------------\n\nThe theories of heredity attributed to Gregor Mendel, based on his work with pea plants, are well known to students of biology. But his work was so brilliant and unprecedented at the time it appeared that it took thirty-four years for the rest of the scientific community to catch up to it. The short monograph, Experiments with Plant Hybrids, in which Mendel described how traits were inherited, has become one of the most enduring and influential publications in the history of science. \n\nMendel, the first person to trace the characteristics of successive generations of a living thing, was not a world-renowned scientist of his day. Rather, he was an Augustinian monk who taught natural science to high school students. He was the second child of Anton and Rosine Mendel, farmers in Brunn, Moravia. Mendel's brilliant performance at school as a youngster encouraged his family to support his pursuit of a higher education, but their resources were limited, so Mendel entered an Augustinian monastery, continuing his education and starting his teaching career. \n\nMendel's attraction to research was based on his love of nature. He was not only interested in plants, but also in meteorology and theories of evolution. Mendel often wondered how plants obtained atypical characteristics. On one of his frequent walks around the monastery, he found an atypical variety of an ornamental plant. He took it and planted it next to the typical variety. He grew their progeny side by side to see if there would be any approximation of the traits passed on to the next generation. This experiment was "designed to support or to illustrate Lamarck's views concerning the influence of environment upon plants." He found that the plants' respective offspring retained the essential traits of the parents, and therefore were not influenced by the environment. This simple test gave birth to the idea of heredity. \n\nMendel's research reflected his personality. Once he crossed peas and mice of different varieties "for the fun of the thing," and the phenomena of dominance and segregation "forced themselves upon notice." He saw that the traits were inherited in certain numerical ratios. He then came up with the idea of dominance and segregation of genes and set out to test it in peas. It took seven years to cross and score the plants to the thousand to prove the laws of inheritance! From his studies, Mendel derived certain basic laws of heredity: hereditary factors do not combine, but are passed intact; each member of the parental generation transmits only half of its hereditary factors to each offspring (with certain factors "dominant" over others); and different offspring of the same parents receive different sets of hereditary factors. Mendel's work became the foundation for modern genetics. \n\nThe impact of genetic theory is no longer questioned in anyone's mind. Many diseases are known to be inherited, and pedigrees are typically traced to determine the probability of passing along an hereditary disease. Plants are now designed in laboratories to exhibit desired characteristics. The practical result of Mendel's research is that it not only changed the way we perceive the world, but also the way we live in it. \n\nI Hope u get ur answer for more halp contect on don_turtel@yahoo.com Whish u all the bet for homework-project

In the last few years of the 18 cetury (I estimate between 1793-1799) Baron Franz Xaver von Zach ordered a group of 24 astronomers to find a "missing planet" (the planet we know now as neptune) to solve the mystery of uranus's strange rotation.  However, the first asteroid discovered, 1 ceres, was discovered by accident by Giuseppe Piazzi.  Later, there were several other found.  The ammount keep going on through today!

Of course, it's difficult to say. The understanding of the cosmos is full of extraordinary ideas and insights. I'd tend to mention Copernico, who first stepped on the modern view of the Universe putting the Earth moving around the sun. And then Kepler, who gave the three fundamental laws of planetary movement, based on the extremely accurate and extensive data collected by Tycho Brahe WITHOUT a telescope.  And of course, Einstein. His General Relativity Theory is the cornerstone of the current cosmology.

The apple story is an exaggeration at best, a myth at worst.  I don't know too much about it, but my understanding is that Kepler had made three assertations concerning the motion of heavenly bodies and Newton found the mathematics that fit the results.  Everyone knew the moon hung in the sky, circling the Earth forever, but no one knew why.  On Earth (where people draw most of their experiences and intuition), it seemed that objects wouldn't accelerate on their own accord unless they were in contact with something.  Newton's insight was that objects can accelerate without contact, and the same force that pulls objects (like apples) towards the ground is the force that "holds" the moon in its orbit.
