__Einstein__ By: Shelby Moinette
 * Einstein was born on March 14, 1879
 * Einstein won the Nobel Prize for his explanation of the photoelectric effect.
 * He is also created for coming up with the theory of relativity. This is also known as E=mc2
 * Einstein past away on April 18, 1955

1.) Nicolus Copernicus- Nicolas copernicus created the scientific reveolution. He believed that, instead of the earth in the center of the universe with god looking down upon us, the sun was in the center of te universe with other plantets rotating around it.

//**__ Sir Isaac Newton __**//
//** Sir Isaac Newton created the theory of gravity and the 3 laws of gravity as listed below...... **// //** 1.What goes up must come down. **// //** 2. For every action there is an opposite reaction. **// //** 3. Gravity is a force that pulls us to the ground,,, cause without gravity we would float into space **// //** Newton's Law of Gravitation is used today to determine the mass of celestial bodies and the interactions between them. **// //** The __law of gravity__ was not Newton's only important contribution to astronomy, his discoveries in light and optics were equally important. **//

//** Newton developed a new telescope used a reflecting mirror which greatly increased the magnification. The first telescope he constructed was only six inches long and through it Newton was able to see Jupiter's satellites. **// //**By: GODWIN DJOKOTO**// 1. Aristotle was born around 384 BC in Stagirus on the Chalcidic peninsula of northern Greece. 2. He believed that the universe was a sphere and finite because a sphere is the most perfect shape and it had a center and a body with a center could not be infinite. 3. He believed it was relatively small compared to the stars and always at rest. 4. He treated astronomy in the abstract, linking it to his overall philosophical world. //**By: Thomas Crutchfield**// //**Galileo Galilei:**// //**Galileo is most credited with the __invention of__ the telescope. He also developed and created other inventions like the thermoscope and the apparatus. The thermoscope showed changes in heat and were first created in 1592. The apparatus helped Galileo perform experiments along an inclined plane. It __confirmed__ his law on falling bodies.**// //**Tiffany Kemple**//
 * //Aristotle//**

__**Johannes Kepler: **__ Known for his three laws of planetary motion, Johannes Kepler also laid the foundation of modern optics. Along with his deep interest in astronomy, Kepler was also fascinated with __astrology__ and __astrological__ conjunctions. __Kepler's three laws: __ 1. Planets move around the sun in ellipses, with the Sun at one focus 2. The line connecting the Sun to a planet covers equal areas in equal times 3. The "semi- major axis" of the ellipse, half the sum of the smallest and greatest distance from the Sun **By Chelsea Blanton **

**__Eratosthenes of Cyrene__**
 * He's probably __best__ known for the accurate measurement of the earth's circumference.
 * He measured the distance between the earth and the moon and the earth and the sun.
 * He also determined the obliquity of the Ecliptic, accurately measured the earth's tilt, and created a star map with 673 stars.

Tyco Brache became most famous for creating precise astronomical measurments of the solar system. and one of his greatest accomplishments was in 1572 he found a super nova near the cassiopeia constellation. he had an instrument called the instrument of brah which made it so that he could precisly observe the motions of the planets. he had extensive data on mars which actually helped kepler in his laws of planetary motion.

Edwin Hubble Edwin is one of the most notable astronomers for changing the overall understanding of the universe. He is most famous for proving that there are more galaxies within the universe than the milky way galaxy that we live in. He is also noted for his arrangement of groups of galaxies called the hubble sequence by use of the Hooker Telescope. By Nick Mehler


 * [|Marie Curie] -**
 * She partnered with her husband in her labs and experiments.
 * She developed ways to separate radium from radiation leading to many current practices.
 * She became the Director of the Curie Laboratory in the Radium Institute of the University of Paris.

__**Claudius Ptolemy**__ Ptolemy was born in 90 A.D in a region of Ancient Egypt. He worked with astronomy, geography, astrology and mathematics. Several things were named after hime like: Ptolemy's theorem in geometry, Ptolemy star cluster, and Ptolemaeus craters on Moon and Mars. Ptolemy's is most known because he is one of the most important works in ancient astronomy. He described a geocentric model of the solar system..

__** Immanuel Kant **__
====Immanuel Kant was a German philosopher. He researched, lectured, and wrote on philosophy and anthropology at the end of the 18th century enlightenment. Kant's goal was to move beyond what he took to be traditional failures of philosophy and unite reason with experience. Kant believed that time and space are not materially real but the idea of a priori condition of our internal intuition. He made an important astronomical discovery, talking about the nature of the Earth's rotation. Kant concluded that time is not a thing in itself determined from experience, objects, motion, change, but a framework of the human mind.==== =By: Taylor Smith=

**__Galileo Galilei__**
was an Italian physicist, mathematician , astronomer, and philosopher who played a major role in the scientific revolution. His achievements include improvements to the telescope and consequent astronomical observations and support for Copernicanism. Galileo has been called the "father of modern "Observational astronomy", the "father of modern physics", the "father of science,"and "the Father of Modern Science".

ALBERT EINSTEIN My favorite scientist of all time was born in Ulm Germany on March 14th 1879. He worked in a patent office in 1905 in Bern Switzerland. This year came to be known as his Annus Miribilis and as a Latin student I can tell you that it means Miracle Year. It was during this time that he obtained his doctorate degree and published four of his most influential papers that included the theory of special relativity, including the famous equation E=mc2. In the year of 1915, Einstein completed his General Theory of Relativity and in 1921 he was awarded the Nobel Prize in Physics. His iconic status was cemented in 1919 when Arthur Eddington's expedition confirmed Albert Einstein's prediction. It also launched him to international superstardom and his name became a household word synonymous with genius all over the world. Einstein emigrated to the United States in 1933 and lived in Princeton, New Jersey and a professorship at the prestigious Institute for Advanced Study. Today, the practical applications of Einstein's theories include the development of the television, remote control devices, automatic door openers, lasers, and DVD-players. Einstein was recognized as TIME magazine's "Person of the Century" in 1999. - Elise Cortie
