    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 with

    Quantum Mechanics In 1758 scientist found that the gases giving off by the burning materials emitted different colors of lights of spectrums. Not all the colors of the rainbow appeared and they were black gaps in the spectrum. 1802 it was discovered the solar spectrum had tiny gaps‚ they were many thin dark light in the rainbow colors. 100 years ago ‚ the hot solid gave continuos spectrum and the overall color of the line revealed the temperature of the object. This discovery made it possible

    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 wave

Particles have multiple virtual motions and each motion is accompanied by a wave. The strength of the total particle wave at each point corresponds to the probability that the particle may be found there. Applying this principle we can explain all kinds of phenomena‚ from the properties of atoms and radioactivity to light reflection. 2. Electron Double

    Quantum Mechanics Notes Matter can be understood by applying two scientific models: particles‚ and waves Particle Models Particles are objects that are hard‚ have mass‚ and move according to Newtonian mechanics. Particles are a macroscopsic model which can be applied to the microscopic world. Kinetic model of a gas: gas molecules are small‚ hard particles bouncing off of one another and the walls of their container. Macroscopic phenomena of pressure and volume are explained in terms of masses

    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 Theory and Postmodern To know what effect if any quantum theory has played on postmodern ideas‚ we must first know what quantum theory is. "Quantum Theory is the most successful set of idea ever devised by human beings. They Quantum Theory explains the periodic chart of elements and why chemical reactions take place. It gives accurate predictions about the operation of lasers and microchips‚ the stability of DNA and how alpha particles tunnel out of the nucleus." (Barlett) What is being

    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 electron

    presented the beginning of his Quantum Theory. Since this time studies have commenced on the nature and behaviour of matter and energy on the atomic and sub atomic level. While it is highly unlikely to see these natures directly without scientific equipment‚ the effects and changes that occur are known as a paradigm shift and can be acknowledged in everyday life. One example of this is the subatomic structure in relation to light. Unlike the newly discovered Quantum theory‚ Newton’s Law studies the

    Max Karl Ernst Ludwig Planck was born in Kiel‚ Germany on April 23‚ 1858 (Foundation‚ 2014). 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 earliest

    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 that

Whereas digital computers require data to be encoded into binary digits (bits)‚ each of which is always in one of two definite states (0 or 1)‚ quantum computation uses qubits (quantum bits)‚ which can be in superpositionsof states. A theoretical model is the quantum Turing machine‚ also known as the universal quantum computer
