Quantum electronics

Erwin Schrödinger was a physicist pioneer who gave a series of lectures in 1944. They were published under the title What is Life? (Harold, 2001). Though philosophical in nature, many have wondered if life can be reduced to biology or even further down to chemistry. This sent many scientists looking for the answer and spawned the guiding question, could human life be artificially created at the cellular level? This would consist of arranging the correct amounts of various elements into the…

The Quantum-Mechanical Model of the Atom Introduction: The theory of quantum mechanics explains the behavior of the particles, such as photons (particles of light) and electrons, in the atomic and subatomic realms. Since the electrons of an atom determine many of its chemical and physical properties, quantum mechanics is foundational to understanding chemistry. Quantum-Mechanical Model- a model that explains the strange behavior of electrons Electromagnetic Radiation- a type of energy…

system” In 1905 German physicist Albert Einstein published the first paper of a new age of Physics. His theory of special relativity, followed by general relativity and the Einstein Field Equations in 1915, and the Copenhagen interpretation of quantum mechanics in 1925 combined to form a more significant shift in natural philosophy…

Imagine, if you were not yourself, yet at the same time you were. Imagine that you had led a completely different life. Maybe you were a soldier, an engineer, a banker, or maybe you did nothing with your life. What if you were born a with a different name, different gender, a different race; what if you were not born at all. Imagine a world where the American Revolution never happened, The Allies fell to the Axis, or the Cold War ended in nuclear annihilation. However, none of these scenarios…

The theory of backwards causation, or retro-causation, has been given much attention in the past twenty years. It has made waves in metaphysics, quantum physics, and even religion. In the case of religion, it pulls into question God’s divine foreknowledge, in other words omniscience. This is an attempt to reconcile the foreknowledge of God with the possibility of backwards causation. Thus if is it impossible to do so then the options present themselves as: God has no divine foreknowledge,…

The visible pulse (gating pulse) enters the microscope, and together with the ultrafast electron pulses illuminate the nanostructure specimen (gold nanoparticle). The visible laser pulse kept at low power (~1.8 mJ/cm2) to avoid saturation. At the spatiotemporal overlapping, the coupling between the visible and electron pulses takes place. The signature of this coupling can be revealed by measuring the electron energy spectrum using the electron energy spectrometer attached to the microscope. The…

Otto Hahn was a great scientist that did multiple things to advance the scientific field. Otto Hahn was born March 8, 1879 and died on July 28, 1968. In his early years he was debating being an architect but later went on to become a German chemist. Hahn attended the University of Marburg and recieved his doctorate degree in 1901. He served one year in the military. In 1904, he went to London to learn English and ended up working at the University College. At University College, Hahn ended up…

The book, The Disappearing Spoon by Sam Kean explores each of the elements on the periodic table. The Disappearing Spoon focusses on the history of the Periodic Table by telling stories that show how each element affected the scientists that discovered it. For each element, Kean supplies an extensive backstory for its foundation, the common (or uncommon) uses of the element and other useful factoids about the matter. The author begins the novel with a physical description of the Periodic Table…

Introduction “The Radioactive Boy Scout is about David Hahn who has a love for science. David starts out working on his boy scout badge, but soon turns to nuclear energy. He soon starts on a new project; building a nuclear breeder reactor. Posing as a physics professor, David solicited information on reactor design from the U. S. Government and from industry experts. He spent a lot his time in the garden shed putting things together to help him with his inventions. Key Idea 1 David's parents…

John Dalton was born Sep 6, 1766 in a modest Quaker family in Cumberland, England. John always strived for a good education, but his family was very poor. When he was 12 he taught at the school he went to. When John was 14 he spent a year working as a farmhand, but went back to teaching at a boarding school in Kendal.Four years later and he was made principal of the school. When John was 26 he was a teacher of mathematics and natural philosophy at Manchester’s New College. In 1794, being his…
