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…

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…

Niels Bohr was born on October 7, 1885 and died November 18, 1962. Bohr was one of the four outstanding scientist who helped construct the atom. Niels contributed to the atomic structure and quantum theory. He received the Nobel Prize in Physics in 1922 for his work. Bohr was a physicist, philosopher, and a promoter of scientific research. Bohr’s proposal stated that the electron revolve in a stable orbit around the nucleus and that the energy levels in which the electrons are on are discrete.…

Introduction Alice in Quantumland is an allegory of quantum physics by Robert Gilmore. In this book Robert sends Alice to Quantumland, a whole new Wonderland, smaller than an atom, where each attraction demonstrates a different aspect. The book is about quantum physics and makes a story about it, making it more understandable. Key Idea 1 Bosons are particles that follow Bose-Einsteins statistics. It makes up one of the two classes of particles, the other is fermions. Fermions are electrons,…

Like any regular person, Danny hated colds. He used to get them all the time before the accident, at least six to eight times a year. Jazz suggested that it was probably a weakened immune system do to too much exposure from his parents' ectoplasmic experiments from a young age. Ironically, it was one of their experiments that ultimately strengthened his immune system from any kind of cold or common sickness. Or so he had thought. Apparently, while he was resistant to most human diseases, he…

Light is an electromagnetic radiation that can be detected by humans. Electromagnetic radiation happens in an extremely large range of wavelengths from gamma rays to radio waves. Within that spectrum the wavelengths visible to humans are few. Light is very difficult to define, in the sense that scientist have been arguing weather light is a particle or a wave. Many experiments have been done to proof weather light is a particle or a wave. The truth is that light sometimes acts as a wave and…

Rebecca McKenney Astronomy 101 Mrs. Alburg 25 March 2017 Chapter 2 Review Questions 1. For each of the following wavelength, state whether it is in the radio, microwave, infrared, visible, ultraviolet, X-Ray, or gamma portion of the electromagnetic spectrum and explain your answer.

The purpose of this spectroscopy experiment was to determine if the spectra matched the electronic transitions that occur in the hydrogen atom among several other atoms. We used the Bohr model of atomic structure to determine the orbit numbers that correspond with the spectrum emitted by the hydrogen atom. The Bohr model states that electrons will never be found in between states, but rather completely in one state or the other. We used this model to determine the initial n value at which the…

Swap the tights for a $3000 suit and the Batmobile for an Aston Martin, and voila, you’ve got yourself a hero! However, James Bond, being the egotistical character that he is, isn’t quite as merciful and emotionally driven as our everyday heroes, which makes us wonder, is Bond a hero… or not? 2006 film Casino Royale directed by Martin Campbell, is the first of the James Bond movies to star Daniel Craig as 007. Armed with a Walther PPK and a license to kill, Bond sets out on a daring mission to…
