  • Two Major Limitations Of Molecular Orbital Theory (MOT)

    Molecular Orbital Theory (MOT): The VBT has two most serious limitations that electrons in molecules are treated as though they are localised and behave almost as they did in isolated atoms. This means that the VBT retains the individuality of the atoms composing molecule. The problem can be resolved by introducing the resonance theory, but with the loss of the original valence bond model. Hund[ 173], Mulliken[ 174], Van Vleck[175], Helsenberg[176], Jones[ 177] and others suggested an alternate…

  • Albert Einstein: Time Dilation

    Most people imagine time as a constant. Physicist Albert Einstein illustrated that time is an illusion that it is relative which it can differ for different observers depending on the speed through space. To Einstein, time is a fourth dimension and space is described as a three-dimensional field, which provides a traveler with coordinates such as length, height and width showing location. Time provides one more coordinate direction although conventionally, it only moves forward. Time…

  • Significance Of Electromagnetic Radiation And Beer Lambert's Law

    by describing light as a wave. Some other properties such as emission and absorption are better explained by treating light as a particle. The correct or exact nature of electromagnetic radiation is not clearly known, as it has the development of quantum mechanism in the first quarter of twentieth century. Wave properties of electromagnetic radiation Electromagnetic radiation consist of oscillating magnetic and electric…

  • SWAN Model Analysis

    Model descriptions SWAN model The SWAN model [12,18] is based on the spectral action balance equation rather than the spectral energy balance equation. The evolution of the action density N is governed by Komen et al. [13]: ∂N/∂t+∇_x ⃗ ∙[((c_g ) ⃗+U ⃗ )N]+(∂c_θ N)/∂θ+(∂c_σ N)/∂σ=S_tot/σ where, N(σ.θ) is the action density spectrum, x is space, t is time,θ is wave direction, σ is relative frequency, S_tot is the source term total, and c_g represents the propagation velocity. The first term in the…

  • The Evolution Of Atoms: The Billiard Ball Theory

    recent model of the atom. It is based on quantum mechanics. Quantum mechanics are the use of the quantum theory as a means to studying the structure and behavior of atoms and molecules. The quantum theory is a theory in physics based on the principle that both matter and energy behave as both particles and waves, and that matter and energy are composed of tiny units of electromagnetic energy called quanta. The electron cloud model and the quantum mechanics model are two different models…

  • Erwin Schrödinger: The Cell Theory

    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…

  • Ernest Rutherford's Atomic Model

    An atomic model is a proposed idea of what an arrangement of an atom thought to look like. Many physicists such as Dalton Billiard, J.J. Thomson, Ernest Rutherford, and Neil Bohr proposed these ideas and made models based on their own ideas. Out of these physicists, Ernest Rutherford’s planetary model is the most generally accepted atomic model. Ernest Rutherford is a New Zealand born son to a Scottish wheelwright and an English schoolteacher. He did well in school academically as a child and…

  • Disadvantages Of Photoacoustic Spectroscopy

    Photoacoustic spectroscopy (PAS) is a tool to study thermal emission resulting from non-radiative relaxation followed by absorption of radiation. PAS was studied primarily by Alexander Graham Bell, John Tyndall, Wilhelm Rontgen and Lord Rayleigh in 1884. For the history of PAS, was not until 1975 that photoacoustic spectroscopy started to be used as a wide range of different applications. This technique provides the following main advantages over the known types of spectroscopy. The advantages…

  • Essay On Backwards Causation

    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,…

  • Disappearing Spoon Chapter Summary

    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…
