helium atom is an atom of the chemical element helium. Helium is composed of two electrons bound by the electromagnetic force to a nucleus containing two protons along with two neutrons, depending on the isotope, held together by the strong force. Unlike for hydrogen, a closed-form solution to the Schrödinger equation for the helium atom has not been found. However, various approximations, such as the Hartree–Fock method, can be used to estimate the ground state energy and wavefunction of the atom. Historically, the first such helium spectrum calculation was done by Albrecht Unsöld in 1927. 
Helium (from Greek: ἥλιος, romanized: helios, lit. 'sun') is a chemical element; it has symbol He and atomic number 2. It is a colorless, odorless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements, and it does not have a melting point at standard pressures. It is the second-lightest and second most abundant element in the observable universe, after hydrogen. It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and Jupiter, because of the very high nuclear binding energy (per nucleon) of helium-4, with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, the vast majority of which was formed during the Big Bang. Large amounts of new helium are created by nuclear fusion of hydrogen in stars.

  "The Golden Number is not the product of mathematical imagination  but the natural principle of the laws of equilibrium."  From averages established from measurements of the human body, it has been proved that the navel divides the total height of the body in the proportion of Φ to 1.  This formula is applied to classical Greek sculpture, and  in Egypt as well, except that in Egypt                                                             the crown of the head is excluded.  Let us recall, in this regard, the significance of the value Φ and  the geometric structure that defines  Φ. The value , or the Golden Number Φ , corresponds to the proportion    C / B = B / A                            when C = A + B  There i...

Uncertain certainty expanded

Heisenberg's uncertainty principle can be explained thus:   1.if it is possible to locate precisely a moving object at a given moment, 2.  it is no longer possible to know its exact speed at this moment.  Inversely,  If one can  specify the speed of a moving object at a given moment,  then it will be impossible to know its exact location.  3.  Certainly it is a matter of intra-atomic phenomena.  The fact of observing the location of the electron—or at least the probability of its position—signifies an action in regard to it, which modifies it or changes its course.  Thus, the fact of observing the phenomenon modifies its nature, so that, at a given moment, only one of the two elements can be known exactly:  either  its location  or  its speed  We can later "group" these data, separately observed, in order to   ignore   acknowledge the simultaneous phenomenon  without really knowing it at all ...

Spectroscopy in Theory aka Ψ Φ μθσιχ PSIPHI Musi~ch

  Theory [ edit ] The underlying premise of spectroscopy is that light is made of different wavelengths and that each wavelength corresponds to a different frequency. The importance of spectroscopy is centered around the fact that every element in the  periodic table  has a unique light spectrum described by the frequencies of light it emits or absorbs consistently appearing in the same part of the electromagnetic spectrum when that light is diffracted. This opened up an entire field of study with anything that contains atoms. Spectroscopy is the key to understanding the atomic properties of all matter. As such spectroscopy opened up many new sub-fields of science yet undiscovered. The idea that each atomic element has its unique spectral signature enabled spectroscopy to be used in a broad number of fields each with a specific goal achieved by different spectroscopic procedures. The  National Institute of Standards and Technology  maintains a public Atomic Spec...
