    Quantum Mechanics ~Three physicists were instrumental: Heisenberg, De Broglie, and Schrodinger ~Their approach stemmed from De Broglie's matter wave concept known as "Wave Mechanics" or "Quantum Mechanics" ~ Bohr's model was inefficient for atoms other than hydrogen or poly-electronic atoms ~ This new approach to a model of the atom focused on the concept of wave functions ~ Since electrons are particles and therefore have wave properties ~ Schrodinger viewed the electron as a standing...

  • Quantum Mechanics - 8414 Words
    Quantum mechanics is one of the major revolutions in 20th century Physics. It is probably the closest science has come to a fundamental description of the underlying nature of reality. And yet it is totally bizarre—it flies in the face of all our intuition and common sense. It sounds more like science fiction, or a poorly written fantasy, than notions which serious scientists would entertain. In this paper, we attempt to explain some of these fantastic notions for the layman. This paper comes...

  • Quantum vs. Classical Mechanics
    Classical and Quantum mechanics are the two main fields of mechanics in physics. Classical mechanics came a few hundred years before Quantum mechanics. Subsequently it is less accurate and less reliable then the more recent mechanic field of Quantum mechanics. Despite being outdated, Classical mechanics can still be used for many everyday problems with bigger and slower moving objects. However, when dealing with extremely fast moving or small subatomic particles a Classical approach will not...

    Quantum tunneling refers to the instance when a particle breaks through a barrier that is normally impassible. The basis of Quantum tunneling and how it functions can be summed up in this equation: (change in E)(change in t) = h. Although we can't change the total amount of energy without violating the law of conservation of energy, we can "borrow" some energy (change in E) to get over the barrier as long as we repay it in time: (change in t) = h / (change in E). The reason a particle can do...

    Quantum Numbers Quantum Numbers The Bohr model was a one-dimensional model that used one quantum number to describe the distribution of electrons in the atom. The only information that was important was the size of the orbit, which was described by the n quantum number. Schrödinger's model allowed the electron to occupy three-dimensional space. It therefore required three coordinates, or three quantum numbers, to describe the orbitals in which electrons can be found. The three coordinates...

  • Quantum physics: The photoelectric effect
    Quantum physics: The photoelectric effect What is the photoelectric effect? The photoelectric effect is when a clean metal surface emits electrons after light, especially ultraviolet, has been shone on at it. This happens because of a process called photoelectric emission whereby a single photon package of electromagnetic energy, called a quantum, is absorbed by metal surfaces. This energy is then transferred to one single electron which can then be released by the metal and that released...

He was awarded the Nobel Peace Prize in 1918 and developed what would come to be known as “Planck’s Constant” in quantum theory. During his collegiate years he studied under Gustav Kirchoff, who developed Kirchoff’s Law for current and voltages. He suffered a personal tragedy when one of his sons was killed for his participation in an assassination attempt against Adolf Hitler in 1944. Planck’s...

    The Impossibility of Quantum Teleportation due to Heisenberg’s Principle of Uncertainty The classical concept of teleportation is simple in theory, but much harder in practice. Imagine two boxes; namely Box A and Box B. The aim is simply to get the contents of Box A into Box B. This is done by gathering all the information of the contents of Box A and sending it to Box B, where the information may be used to recreate it. In theory this is quite simple, ignoring the low supply of...

  • The Atom - 1555 Words
    The Atom The term atom was coined by the Greek philosopher Democritus, around 460 B.C. Being a philosopher he proposed the question “If you break a piece of matter in half, and then break it in half again, how many breaks will you have to make before you can break it no further?” . He thought that at some point matter would become too small to divide again-this basic matter particle was what he called an atom.

    In optics, corpuscular theory of light, originally set forward by Pierre Gassendi, states that light is made up of small discrete particles called "corpuscles" (little particles) which travel in a straight line with a finite velocity and possess kinetic energy. It was largely developed by Sir Isaac Newton. Newton's theory remained in force for more than 100 years and took precedence overHuygens' wave front theory, partly because of Newton’s great prestige. However when the corpuscular theory...

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...

It’s a “thing,” he says, “a bundle of energy, an indivisible unit that can be sliced no more” as Max Planck’s observations 100 years ago indicate (41). Wheeler’s words ‘thing,’ ‘bundle,’ and ‘sliced’ are interesting: they seem at once colloquial and correct for the usage Wheeler makes of them. Quanta sound friendly, everyday.
