In the following, I will argue that Einstein’s discovery of the theory of special relativity was ultimately positive in terms of its benefits. First, Einstein’s discovery changed our understanding of space and time. Second, Einstein’s discovery has a positive effect on people’s daily lives, for example, the global positioning system (GPS). Third, Einstein’s theory of special relativity is a scientific theory, which according to dictionary.com is “a coherent group of propositions formulated to…

However difficult life may be, there is always something you can do and succeed at,” said Stephen Hawking. Stephen is one of the most brilliant scientists of the 20th and 21st centuries. Hawking is most known for his work in black holes, and cosmology. He also done many other things as well, he has written many books, and has taught as a professor at several universities. Stephen Hawking was born on January, 8, 1942 in Oxford, England. His parents were both well educated, and knowledgeable…

Overall, the purpose of this lab is to find the ideal substance in which to fill the tires in a rover that will go into space ( Mars ). We tested the speed and total distance traveled for the control ball and the foam filled ball. For speed I thought the foam filled ball would go farther because it weighs more than the control ball, and for distance if the ball goes on the ramp, it will lose speed , and if it hits the speed bump then it will lose speed in total for both, reducing the total…

The subject of quantum physics appeared far-fetched to physicists of the late 18th and early 19th century. Now, scientists hold a better understanding of atoms and their properties because of this branch of physics. Many scientists helped create the utterly confusing and frightening field, but three in particular made improvements to it that directed modern scientists to where they stand today. People do not grant enough credit to Max Planck, Albert Einstein, and Louis-Victor Broglie, the…

1a) The incandescent bulb produced a continuous spectrum because all wavelengths were observed. Rutherford’s model predicts that the spectrum of hydrogen should be continuous as well. b) During the demonstration, a continuous spectrum was observed for incandescent light and a line spectrum was observed for hydrogen; therefore, my observations seem to contradict with Rutherford’s model. Rutherford hypothesized that atomic spectra should always be continuous because he believed that electrons…

Crumple zones are structural features mainly used in automobiles such as cars and trucks. They are designed to absorb the energy from the impact during a traffic collision by controlled deformation. Normally located at the front part of the vehicle, in order to absorb the impact of a head-on collision, though they may be found on other parts of vehicles as well. Crumple zones, are secondary safety features, this is due to the fact that secondary safety features only come into play once you have…

For task one My hypothesis was "If the forces on each side of the rope are equal, then the sum of forces will be zero. If we can determine the force each person on both sides of the rope, then we can determine if the sum of their forces will equal zero. " which was, correct. I know my hypothesis was correct because of the balanced force. A balanced force is when you have an equal amount of force on each side of an object when force is being exerted on it, it doesn't move because there is no…

Learning Experience number ( 2 ) 1- Arnold Dumbbell Press - raising the dumbbells as i rotate the palms of my hands , is the concentric motion. The second phase, as I lower the dumbbells back down, is the eccentric motion, . as i pause while the the dumbbels are at the top, is the isometric contraction. 2- Alternate Hammer Curl - as I curl the weight toward my shoulders, is the concentric motion. as I lower the weight back down, is the eccentric,motion. As the weight is held at the top of the…

The purpose of the experiment was to determine how altering the amount of mass in a makeshift rocket will affect its distance. Our hypothesis stated that when more mass is added to the rocket, its distance will also increase. To investigate this theory, we conducted an experiment in which the mass of the rocket would be changed using differentiating amounts of water. To measure the height of the bottle rocket, we took rope and attached it to the girth of the liter bottle to determine how high…

Stress is a state of mental or emotional strain or tension resulting from adverse or very demanding circumstances (Webster). Located at the center of the nervous system is one of the body’s most important organs, the brain. The brain is an extraordinary part of your body as is it processes every thought you have, and every word you say, by sending signals through your nervous system. There are many disorders that can inhibit the brain from functioning normally, however the one thing that can be…
