The four fundamental forces have been around before mankind. These forces shape the way we live and interact with the objects around us on a daily basis. These forces are so important, they are in existence throughout the entire universe. Black holes, the formation of planets, galaxies and stars are all because of gravity and these same celestial bodies have their own electromagnetic forces and the strong and weak nuclear forces are. Since everything in the universe is made of atoms, there is…

The Spirit Phone After the carnage of World War I, spiritualism was undergoing a revival, and many people hoped science could provide a means to contact lost loved ones. Edison himself was not a believer and admitted he had no idea if a spirit world even existed. Edison corresponded with British inventor Sir William Crookes, who claimed to have captured images on "spirit photographs." Edison was intrigued. Edison took the idea of the telephone and the telegraph a bit further and announced in…

Temporal outliers are common trajectories that follow the populated route, but with an important difference of the speed compared to the other common trajectories. For extracting such type of outliers, we make use of the average speed used by the moving objects in the populated route, we make comparison between each sub-trajectory from the common trajectories and the average speed for all common trajectories that traverse the same route with some tolerance, and we extract two essential types;…

1. What is the GPS Standard tied to this project? The GPS Standard tied to this project is - S8P3. Students will investigate relationship between force, mass, and the motion of objects. 2. How does your rubber band car show Newton’s 1st Law of Motion? The first law states an object will stay at rest until acted upon unbalanced force. The car is at rest until the rubber band is twirl all on the stick. This mean a force has to be added for the rubber-band car to move. 3. How does your rubber…

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…
