Radiation is a term overused by people who are fascinated and well-versed in the field of science. It can very well be considered a household term especially with the arrival of computers and mobile phones. People normally perceive radiation to be harmful; but little do they know that without radiation all things would cease to […]
Among the most dreaded subtopics in the complicated and mind-draining course of physics, which most students would rather avoid, is momentum. Imagine all the units of measures to memorize, not to mention formulas. However, whether people like it or not, momentum is very present in this world from the tiniest atoms to the largest celestial

essay writer website Photo by: ESO Creative Commons What do Christian Doppler and Albert Einstein have in common? Simple, they are both instrumental in weather forecasting through their contributions to the information people know about radial velocity. Without understanding how radial velocity works, warnings about tornadoes and hurricanes are not possible.
Outgassing is a process wherein gas is released through sublimation, evaporation and phase conversion. It is also simply described to as releasing solid gas. Offgassing, is similar to outgassing only that the latter refers to indoor air quality.
Lagrange points are areas in outer space characterized by gravity along the circular motions in outer space. This phenomenon was theorized by a mathematician from France, Louis Lagrange while studying gravity, most specifically the Three body problem. He aimed to investigate why a third small body would rotate a certain body (Earth), which is also
Tidal force is a secondary effect of gravitational force and its most common manifestation, at least on the planet Earth, are tides. Tidal force, by technical definition is the differential force of gravity which arises because the force exerted on one body by another is not constant across the diameter in that the side which
Photo by: Zedh Creative Commons The small field found at the wide range of frequencies of electromagnetic radiation is called visible light. It can be discerned by the naked eye and has wavelengths measured to be from 780 nanometers to 390 nanometers. Each wavelength has a particular color and when that specific wavelength hits one’s
General relativity is what Albert Einstein theorized in 1916, which describes that gravitation also affects the shape of space and flow of time. It proposed that the bigger the matter, the more it causes the space to curve.

An Electron is the negatively charged subatomic particle. Electrons can be free, like those travelling in an electric current. They can also be bound to an elemental atom. The symbol generally used for this particle is ?e-.? It is virtually weightless when compared to the protons and neutrons. Studies have shown that its weight is
The Electron Volt (eV) is a unit of measuring energy. Remember that for electrons to move, there must be a potential difference or voltage. The electron volt refers to the gained kinetic energy of a single free electron, as it accelerates in a 1-volt potential difference. One eV is approximately 1.602?10?19 J. For astrophysics, the
