Before we know Physics let’s take a quick overview of Science. Science Definition The Study of Nature is called Science Science, as currently defined, proposes critical knowledge and tries to describe reality and explain it by means of laws that are universal propositions that establish under what conditions certain events will occur, thus allowing the …

Is Light Particle or Wave? Bohr considered electrons as particles and light as a wave in his development, Einstein’s concept of the existence of two theories of light (waves and particles) which had not been connected in a logical way had already been accepted. Then another renowned scientist appears Louis de Broglie, who suggested a …
A law on energy conservation and, in exchange, a definite description of heat is the first law of thermodynamics. The amount of energy transferred to a system in the form of heat plus the amount of energy transferred in the form of work on the system must be equal to the increase in internal energy(U) …

Everything in this universe is manifested to our eyes and instruments in two well-known forms: matter and energy. This simple fact, which is true to how far we have come to observe – and at this point, we have come to observe very far – has given rise to numerous scientific, philosophical and even theological …
This baryonic matter that is so well known to us, at its most basic scale, is composed of quarks and usually accompanied by leptons. Leptons (such as electrons or neutrino) are subatomic particles that are subject to electromagnetism, gravity, and weak interaction, but not strong interaction (which is the strongest force in the universe, laying …
The great challenges of today’s science require infrastructures and monstrous investments, among which are the Large Hadron Collider (LHC) – the particle accelerator that started on 10 Sept 2008, the most powerful in the world -, the Pierre Auger Observatory – the largest cosmic ray detector of the moment-, the Cassini Huygens probe – the …
In this article we will be talking about third law of Thermodynamics: Absolute zero, Cryogenics, Adiabatic demagnetization. Change of properties. Applications. Microscopic foundations of thermodynamics. The second principle suggests that an absolute temperature scale with absolute temperature zero occurs. The Third Law of Thermodynamics states that no procedure consisting of a finite number of steps can reach absolute …

It is difficult to say what is real and what is imaginary, what is a new discovery vs vivid illusion. Ideas, concepts, inventions, predictions, foretelling of the future, extrasensory perceptions, parapsychology and such things, all involve vivid imaginative or a mindset free to roam and accept what things arrive within it, rather than putting them …
The temperature of an object actually measures the degree of agitation of the molecules that compose it. The more an object is hot, the more its molecules are agitated by rapid and erratic movements; this is called the thermal agitation. It is said that an object is at a temperature of absolute zero when its …
