On the Subject of Quantum Teleportation “Beam me up, Scotty” Captain James T. Kirk exclaims, as he narrowly escapes a macabre fate at the hands of the Klingon army. A beam of light is cast down onto the captain, instantaneously transporting him aboard the safety of his own starship. This technology, employing the use of teleportation, has saved many U.S.S. Enterprise crew members lives’ throughout countless episodes of the Sci-Fi TV series Star Trek. Teleportation being largely fictional at the…

was born in London England on July 25th, 1920. At just the age of 15 Rosalind Elsie Franklin decided she wanted to be a scientist. Receiving her education at several schools which also includes North London Collegiate School which she excelled in science. She was best known for the role she played in the the discovery of the structure of DNA, also her pioneering the use of X-ray diffraction. Franklin enrolled at Newnham College, Cambridge, in 1938 and she studied chemistry. In 1941 she was…

efforts in the field of theoretical and experimental physics produced a cornerstone in weapon development and the knowledge of the atom, but what can we say accounted for Oppenheimer’s success in his endeavors? Was it his drive for the knowledge of science, or was it the patriotism he had for his country that drove him to work endlessly on the creation of the atomic bomb? In an article in Modern American Poetry called, “About J. Robert Oppenheimer”, we learn that as a child, Oppenheimer became…

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…

In 1974, Stephen’s research led him to a finding that would make him famous in the science world. He discovered that black holes weren’t vacuums like everyone believed them to be. Stephen showed that matter in the form of radiation can escape the gravitational force of a collapsed star. After he shared his discovery he became an instant celebrity in the science world. After his breakthrough Stephen mostly did research, but occasionally would teach at universities as a visiting…

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…

must be broken down. What are photons? How does gravity affect light? What is a black hole? A photon is typically seen as a particle or wave representing a quantum of light or other electromagnetic radiation. A photon carries energy proportional to the radiation frequency but has zero rest mass. Photons are currently best explained by quantum mechanics. However, it is important to know that photons have both the qualities of waves and particles which is known as wave-particle duality. As…

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,…

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…
