Johannes Kepler studied heliocentrism at a University in 1590. Kepler started as an assistant for Tycho Brain 1600 – 1601 and helped observe planet’s orbits but he assumed the orbit was a circle. He first started by looking at Mars. During different times, Mars seemed to have sped by and slowed down. He couldn’t seem to figure out what was causing it. Then the same year Tycho Brain died and told Kepler to keep looking at the stars. Kepler tried to find the mathematical explanation for the movement of Mars. Kepler had failed 40 times before he found out the formula for Mars’ orbit which took five years. Then Kepler realized it must be an ellipse in 1605 which formulated Kepler’s law of planetary motion. Four years later he published his findings in Astronomia Nova and suggested all planets move in elliptical patterns. Kepler also said that, “They move fast near the sun and slower the further from the sun you are.” He argued that the sun pulls the planets to make them go faster the closer they are to the sun.

At 11:40 pm the Titanic collided with an iceberg, but the captain did not find out until later that unforgiving cold night. Just after midnight the captain found out about the flooding of the ship, and he told the crew they had an hour and a half before the boat was drenched in freezing waters. 12:50 am, and the captain sent a distress call to New York. The captain said “We have been struck by an iceberg. Badly damaged. Rush aid.” 20 minutes later the first lifeboats were launched but not everyone evacuated. The first lifeboats were only one-fourth full. One frozen hour later, the propellers and ship sunk under the water, and so did the captain. After 2 hours of waiting, the Carpathia came to the rescue but only got 711 out 2,222 people and in April 18 the survivors arrive.
Alexander the Great was an amazing man. This essay is the tale of his earliest great feats. Since he was born into a royal family, Alexander’s life was chaotic due to his father’s royal position. Phillip II was a battle fighting expert, who taught Alexander his amazing battle tactics. While purchasing a horse, Phillip II saw the horse named Buscephalis, but he was not interested because he heard it was unable to be tamed. The amazing Alexander promised to tame the creature to get it for free. He would pay for it if he failed. So immediately he tamed the massive, muscular horse at age ten overcoming a huge feat that none could seem to conquer but him. The horse was afraid of his own shadow, so he turned it toward the sun and rode, and it worked! Now he had successfully tamed his horse. His father also wanted him to learn from the best, so he took him to the famous philosopher and scientist Aristotle. Aristotle inspired his thirst for knowledge from interests in medicine, philosophy and, history. Then at age 18 he fought at his father’s side in the heat of battle and won the battle of Chaeronea in 338 BC. Two years later his father was brutally assassinated by Pausanias (one of his bodyguards) but was soon taken down by the other bodyguards. Now at 20 years of age, he was the king of Macedonia.
