Quantum mind

explain the behaviour of matter on the atomic level with the laws of classical physics however they were not accurate nor successful. It was not until the period between 1900 and 1930 where a revolution occurred and a generalised formulation called quantum mechanic was developed. And since the understanding of the structure of the nucleus of the atoms led to the development of different technologies and applications. The way how our understanding has grown will be discussed in the follow report.…

Exploration: Research Question: How does the travel distance of light waves affect the distance between the constructive interference fringes in the Double Slit experiment? Personal Engagement/Topic: Light is seen everywhere, artificial and natural. It is so common, that no one really questions it. But what is light made of? Intuitively, I would answer that visible light is a particle. It makes sense, doesn’t it? The photon from the source shoots into the eye’s retina, and the eye’s rods and…

Albert Einstein created a whole new universe of curiosity and discovery through research, experiments, and countless years of dedication to science. Throughout the years of his life, he faced many trials and failures, but those helped him set the foundations for many inventions and findings in the science community. Albert Einstein was an amazing scientist with a curious childhood and an extraordinary adult life, filled with discoveries and findings that ended up impacting science in several…

We now use the method described in Section 2 to studythe effects of electron-phonon interaction on the electronic transport properties of (C60-1X1)2(X=N,B) molecule. We set tC-C=2.5 eV, αC-C=6.31 eV/Å, KC-C=49.7 eV/Å2 [35] tC-B=1.17 eV, αC-B=6.04 eV/Å, KC-B=51.1 eV/Å2,tC-N=1.05 eV, αC-N=6.13 eV/Å, and KC-N=49.6 eV/Å2 [36] and T=300 K in the calculations. The doped atoms are located at about the same distance from each lead and they are indicated with a different color from C atoms in each…

“Matter, though divisible in an extreme degree, is nevertheless not infinitely divisible. That is, there must be some point beyond which we cannot go in the division of matter… I have chosen the word “atom” to signify these ultimate particles.” – John Dalton. John Dalton is a British chemist who was born in September 6, 1766 in Eaglesfield, England and died on July 26, 1844 in Manchester, England. At the age of 12, he started teaching at a Quaker school in Cumberland. Dalton worked as a farmhand…

Physics: Analogy of Light and Sound Light and sound share many common aspects. Today, we will study some of notable similarities and differences between the two. We can perceive both light and sound. We see through eyes and hear through ears. Both light and sound are waves. Light is an electromagnetic wave whereas sound is a mechanical wave. Light is created by interaction of electric and magnetic field. It does not require any medium for propagation, so it can propagate in free space. On the…

fact that certain atomic nuclei exhibit magnetic property to determine their chemical and physical properties for various uses that we’ll discuss later. History of NMR Spectroscopy Year Individual Discovery 1921 Stern and Gerlach Basis of quantum theory is confirmed by carrying out atomic and molecular beam experiments 1925 Ulhenbeck & Goudsmith Discovered the concept of spinning electron to the magnetic dipole moment. 1938 Isidor Rabi Described Nuclear Magnetic Resonance in molecular…

Circular Dichroism (CD) fundamentals. CD is defined as the difference between absorptions of left (Al) and right (Ar) circularly polarized light beams, CD=Al-Ar For each absorption band, the CD of two enantiomers are always exactly opposite. Theory. For each electronic transition one can define an electric (µij≠0) and a magnetic (mij≠0) transition dipole. Both can lead to absorption of radiation, the intensity of which is directly related to the oscillator strength f, fij≈| µij |2+ | mij |2 In…

Gilbert Lewis first introduced his theoretical dot structures in 1916. Today, these same dot structures are used to illustrate the chemical bonding nature of atoms. How did Lewis formulate these brilliantly simple representations of nature? The Lewis Dot Structures we know today actually derive their functionality from Lewis’ own model of the atom, the Theory of the Cubical Atom. This essay will explore the functionality of Lewis’ cubical atom and how this model led to the Lewis Dot Structures.…

In 1959, metal–oxide–semiconductor field-effect transistor (MOSFET) was invented by Dawon Kahng and Martin M. (John) Atalla at Bell Labs. Julius Edgar Lilienfeld had already patented the basic principle of this kind of transistor in 1925. But later the Bell Labs edition was allocated the name bipolar junction transistor, or merely junction transistor, and design of Lilienfeld came to be identified as field effect transistor. Later, Jean Hoerni found that Silicon dioxide (SiO2) should be used to…
