Albert Einstein







Albert Einstein is a very famous scientist for many of his accomplishments and discoveries that affect our world today. Albert Einstein was born on March 14, 1879 in Ulm, in the Kingdom of Württemberg, which we now call the German state of Baden-Württemberg. Albert Einstein died on April 18, 1955 and lived up to the age of 76. The century that Albert Einstein lived in was the 21st century.
Albert Einstein studied in many areas of science. Some of the areas that Albert Einstein studied in were how science currently views time/space, energy, light and gravity. Most of Albert Einstein’s accomplishments in these areas were theories. Albert Einstein major accomplishments in how science currently views time/space were one his theory which stated “That time is not constant as is light, the faster one goes, the slower time is, even though that person does not feel it as being different”, “One practical use for this is knowing that there is a time difference the closer you get to the speed of light” and “There was a Russian cosmonaut that spent 748 days in space (roughly 2 years). That man is now 0.02 seconds younger than he would have been had he never gone to space, because of the slower time in space aboard the MIR space station. For him it doesn’t make that much of a difference, but let’s say that someone wanted to travel to Alpha Centauri, our nearest star. It would take them 5.7 earth years, however they would only age 3.8 years and return at a younger than expected age. So time it is relative, while light is constant.” That tells me that the point of his theory was that time in space is a lot slower than time on earth.
 Albert Einstein major accomplishments in energy was his theory on energy which was “Most everyone has heard of E=MC2, this is the famous equation that shows the relationship between Energy and Mass .It was once thought that Energy and mass were different, however Einstein’s theory states that Energy and Mass are merely different forms of the same thing, similar to Ice, water and gas, all are forms of liquid. Not only that Mass and Energy can be destroyed and changed into one another, as stated in the light theory above. Speed up enough and you will have a gain of mass because energy has turned into Mass. Our sun is burning up hydrogen, turning it into energy that we perceive as light. Since the source of hydrogen is not infinite, the source of light is not finite. However, we have nothing to fear for several million years.” This theory tells me that mass and energy are different and that energy can turn into mass.
Albert Einstein major accomplishments in light were that he first thought up of the "Thought Experiment" and came up with the special theory of relativity in which he stated “that light is constant, unlike the wavelike picture that the scientists of the time had thought it was. Not only that, it is not possible to travel faster than the speed of light 186,000 miles/second (300,000 Km/second). Light always travels at the same speed whether it is on the headlight of a train speeding down the tracks or the light on the lantern shining on the tracks. The light itself always travels at the same speed.” This tells me the speed of light and how it always travels at the same speed.
Lastly, Albert Einstein major accomplishments in gravity were first he added to Newton’s theory of gravitational pull by stating that “not only does the apple fall to the ground because of gravity, but earth’s orbit attracts asteroids (and other space objects) because of the "dent" the earth makes in the "fabric" of space. Thus, giving us the power to our advantage as a "parking space" for satellites in our orbit to use for our technological advantages. It has also been used to get men to and from the moon.” This tells us that gravity is not only in some places but all over. Those were some important things about Albert Einstein and his life earnings.
