Angel flight is a term used by group of people whose members are provided with free air transportation,  because they are in need with free medical treatment far from home. The transportation of passengers are done by volunteer pilots using their own general aviation aircraft. History of angel flight  The first two organisation to be termed "angel flight" was founded in the year 1983. The first organisation was formed in Santa Monica, California known as the "Angel flight of California (presently Angel Flight West)". The second was formed in Atlanta, Georgia and was called "Angel Flight Soars" Accidents and incidents On 15th August, 2011 a Piper PA-28 Cherokee conducting an angel flight crashed in rural Victoria, Australia. On May 24, 2013 an angel flight crashed into a pond in Ephratah, New York. On June 28, 2017 a TBIO Tobago serving an angel flight crashed into a terrain near MT Gambier heading to Adelaide.

A panfish is a kind of fish (usually pursued by recreational anglers) that do not out grow the size of a frying pan. It is a term used by recreational anglers for small fish which could fit into a pan, but it is edible and legal for eating. Example of a pan fish. Species of the panfish  Bluegill (Lepomis machrochirus)  Green sunfish (Lepomis cyanellus)  Redear sunfish (Lepomis microlophus)  Redbreast sunfish (Lepomis auritus)  Spotted sunfish (Lepomis punctatus)  Pumpkinseed (Lepomis gibbosus)  Warmouth (Chaenobryttus gulosus)  The size of a pan fish  However, it is stated above that the size of the panfish is a fish that takes the size of a frying pan. But a typical size of the bluegill exist which is about 4 to 12 inches and has  a maximum size of 16 inches. The largest bluegill ever existed was caught in the year 1950, with an average size of about 4 pounds (12 ounces).

What is the halo effect?  The halo effect is a kind of cognitive bias, that make one part of someone seems more attractive or desirable. This concept can be applied to people, product, brand, business etc.  The halo effect can also be seen as the final judgment of someone towards a person, product, brand, business etc. by their first impression without serious information. For example, if John is working in an office where you work; and you see John as creative guy and someone ask you, "please, do you know someone who can decorate my room?". You will simply recommend John because you think that John is creative. From the above example, you choose John not because you have actually investigated if John can actually decorate a room,  but because you feel that John is creative and could be able to decorate a room.  The halo effect usually refers to when the judgment of the behavior is positive, otherwise if negative it is refer to as "horn effect" How halo e

What is cyanide? Cyanide is a chemical compound that consist of carbon (C) and nitrogen (N). It exist in different forms, so we can say; sodium cyanide, hydrogen cyanide, potassium cyanide and others. Most of these variants (forms of cyanide) are poisonous, that in can cause death within minutes. The origin of cyanide, started from the fact that a huge number of Nazi uses the potassium cyanide suicide pills to kill themselves during the World War II. The most dangerous form of cyanide is the hydrogen cyanide, which is in the form of gas; and is deadly when inhaled. Uses of cyanide  Despite the horrible fact of cyanide as  a poison, cyanide has its own importance as it is useful.  The uses of cyanide include: I. It is used in industrial chemistry, in the production of nylon. II. It is used for pest control, bring the key ingredient in the poison used to kill animals, such as rats and other rodents. III. It is used in the mining of golds and silver, to be able to dissolve these

The Schrodinger equation in quantum mechanics, is a mathematical equation that describes the change over time of a physical system in which quantum effects,  such as wave-particle duality, are significant. The equation is a mathematical formulation for studying quantum mechanical systems. It is used to find the allowed energy levels of the quantum mechanical system (atoms, or transistors). The associated wave function gives the probability of finding the particle at a certain position. The Schrodinger equation exist in different forms: I.  Energy form of Schrodinger equation: $$\frac{E^{2}}{2m} = E - V(r)$$ II. The time independent Schrodinger equation: $$-\frac{\hbar^{2}}{2m} \nabla^{2} \psi(r) + V(r) \psi(r) = E \psi(r)$$ III.  Time dependent Schrodinger equation: $$-\frac{\hbar^{2}}{2m} \nabla^{2} \Psi(r,t) + V(r) \Psi(r,t) = i\hbar \frac{d\Psi(r,t)}{dt}$$ IV.  Auxiliary time dependent Schrodinger equation: $$-\frac{\hbar^{2}}{2m} \nabla^{2} \Psi(r,t) + V(r) \Psi(r,t) = -i

The unified theory of wave-particle duality has been used to derive the Schrödinger equations. The Schrodinger equations are generally accepted, by postulate rather than derivation, to be laws of physics. The Schrodinger equations provide a basis for analyzing many kinds of systems (molecular, atomic, and nuclear) in a particular inertial reference frame. The success of the Schrödinger equations constitutes a basis for accepting them, their derivations, and the unified theory of wave-particle duality which makes such derivations possible. This acceptance is completely justified in the favored inertial reference frame. In accord with the principle of relativity, all physical laws must be the same in all inertial reference frames, i.e., all physical laws must be Lorentz invariant. Recall, the relationship: $$\nabla^{2} \psi = \frac{\partial^{2} \psi}{\partial t^{2}}$$ ...........(1) Equ (1) is Lorentz invariant and reduces, by means of the procedure presented in the previou
