What Is Physics and What Are Its Uses? Physics‚ a branch of science‚ is traditionally defined as the study of matter‚ energy‚ and the relation between them. The interaction between matter and energy is found everywhere. In order for matter to move‚ it requires some form of energy. Sports show many good examples of the relationship between matter and energy. For instance‚ a pitcher requires energy to throw a baseball at the incredible speed and accuracy that is needed to keep the batter from

cName: Nicholas Cassel Gen Chem 1210 23 March 2013 Blinded By the Light Abstract: In this experiment we were provided a cereal box spectrometer to observe the emission lines of noble gases and hydrogen. Based on the scale readings on the spectrometer and the Balmer-Rydberg formula‚ their wavelengths and percent error were able to be extrapolated. Based on the literature values‚ the cereal box spectrometer proved its value as a decently accurate spectrometer. Introduction: Every element

The time I received my diploma‚ I scheduled a tour to Nanjing University‚ known as the top university for Astronomy in China‚ to prepare future study about astrophysics. The lectures impressed me an overall prospective about Astrophysics and their enthusiasm strengthened my focus on this research area. Then I participated in a workshop hosted by National Astronomical Observatory of China (NAOC). NAOC complemented my knowledge of Technologies and Methods in Radio Astronomy which I supposed to be necessary

Einstein’s Theory of Relativity Albert Einstein was born on March 14‚ 1879 in Ulm‚ Germany. As Albert grew up he loved taking lessons on the piano and the violin. Then when he was about ten or eleven he grew the curiosity about mysteries of science. As he grew up into an adult he worked as a patent clerk in Bern‚ Switzerland. This is when Mr. Einstein published four of his research papers‚ one of them being the Special Theory of Relativity or as most people know it as E=MC². By 1915‚ Albert Einstein

Home is Where the Heart is In Ghost Hunter’s recent episode Home is Where the Heart is‚ the ghost hunter team heads to Beardslee Castle in Little Falls‚ NY. Some interesting facts about this castle is that the owner had hanged himself in the house. Along with the hanging other individuals have died in the house. The team investigates to see if they can debunk any of the reported occurrences. The Ghost Hunter team wires the castle/restaurant with video surveillance equipment. By doing this

Wave Nature of Light Objective: The purpose of this lab is to investigate interference‚ otherwise known as the diffraction of light. A beam of light acts a wave‚ and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges‚ allowing light to enter an area of shadow. When waves are superposed‚ they reinforce each other when crests are in phase and cancel out when they are not in phase

It can make them rethink the world in which they live and rethink there entire sense of reality. I do believe this is true in many different ways. People do tend to believe in the reality of the world on which they are presented for many different reasons. For example

What is an excition? What are key parameters to describe an exciton? An exciton is a bound state of an electron and a hole in an insulator (or semiconductor)‚ or in other words‚ a Coulomb correlated electron/hole pair. It is an elementary excitation of a solid. A vivid picture of exciton formation is as follows: a photon enters a semiconductor‚ exciting an electron from the valence band into the conduction band. The missing electron in the valence band leaves a hole behind‚ of opposite electric
