Johannes Kepler

   Johannes Kepler was born on 1571, in modern day Germany, and passed away in 1630 at the age of 58. From a young age, Kepler became a man who suffered from severe illnesses; he was sick from birth, contracted smallpox, and had severely defective vision. He was a devout Christian who believed his vocation was to study works of God. He attended the University of Tuebingen where he studied Latin, Greek, theology, mathematics, and Astronomy. He then proceeded to work in various jobs in the field of mathematics or astronomy like a high school teacher, district mathematician, and assistant of Tycho Brahe(another acclaimed astronomer).
        As an Astronomer, Johannes Kepler's preeminence in terms of establishing the standards of both modern-day physics and astronomy is above all others. Kepler is the man who discovered three laws of celestial bodies called Kepler's Laws. Kepler's Laws are:     

1. First Law
1. The orbit of a planet around the Sun (or of a satellite around a planet) is not a perfect circle. It is an ellipse
2. Second Law
1. A planet’s orbital speed changes, depending on how far it is from the Sun.The closer a planet is to the Sun, the stronger the Sun’s gravitational pull on it, and the faster the planet moves.
3. Third Law
1. The larger a planet’s orbit, the longer the planet takes to complete it.

Because of Kepler's Laws, today we are capable of using: satellites for things like television, communications, weather, and navigation; and calculus as Isaac Newton was able to create(or discover) with Kepler's laws as a foundation which today is used for physics, economics, medicine and even meteorology. Today because of Kepler's laws, Meteorologist are able to use satellites to see whether such as hurricanes, volcanoes, and blizzards and show measure ocean temperatures and prevailing currents and show sea level and altitude. In addition to meteorologists using satellites, meteorologists can also in part thank Kepler for using calculus to determine the gradient of a field. That is, to identify what direction to move in order to see the greatest temperature increase, for instance. And even how much it increases after you go a certain distance in that direction.

Johannes Kepler is the man who has contributed greatly to meteorology and science as a whole. He set the foundation for modern-day science and very well essentially saved millions and maybe even billions of lives as meteorologists are able to use his discoveries to predict weather and save lives.
