Magnetism and nanotechnologyMagnetism and nanotechnology are two fascinating fields of study that have revolutionised science and technology in recent years. The physical phenomenon known as magnetism, an intrinsic property of certain materials, and nanotechnology, the manipulation of matter on a nanometric scale, have intertwined to open up endless possibilities in different areas of application.Magnetism, with ...
Magnetism in technologyMagnetism in technology has evolved over time. It is very present in many areas of our daily lives, being of vital importance for the present and future development of multiple sectors.Since ancient times, magnetic compasses have been used for navigation. And today magnetism is present in a wide variety of modern technologies, from ...
String theoryString theory was first proposed by Jöel Scherk and John Henry Schwarz in 1974 with a paper explaining one-dimensional pillars instead of point particles explaining the gravitational force.String theory is a model of physics that clarifies the nature of matter and its interactions. It also states that space-time has several dimensions in addition to the ...

Biot-Savart LawThe Biot-Savart law was discovered by Jean Baptiste Biot together with Félix Savart. These two Frenchmen started from the formula for magnetic flux density. In 1820, they made several experiments that had to do with the strength of the electric current that meets a nearby magnet.Savart's law is the law by which by applying an ...
The classical free-electron modelThe classical free-electron model consists of metal atoms arranged in a crystalline structure that can vibrate. This electron has a gas-like perception of electrons. Unlike ordinary gas molecules. This type of electron is so-called because they have free charges.The velocity of the free electron is 0 and it encounters the absence of ...
Snell's lawThis law was discovered by Willebrord Snell Van Royen in 1621 and is intended to know the angle of refraction of light as it passes through a surface with a different refractive index.Snell's law can also be seen as the law of refraction of light and Fermat's principle, this law states that the connection that ...
Lambert's lawLambert's law or also known as beer lambert's law establishes the empirical relationship connecting the absorption of light and the properties of a material as light travels.This law was discovered in several different and independent ways, the first to discover it was the Frenchman Pierre Bouguer in 1729.The beer-lambert law is ...
Watt's lawWatt's law was invented by James Watt, an engineer born in Scotland in August 1819. His law is directly related to the development of the steam engine in 1769 and was patented and used in the first industrial revolution.Watt is an English word meaning "Watt". On the other hand, it is most commonly used to ...
PolarizationPolarization is the property that all transverse waves possess that produces a vibration of these with more than one orientation. We can find the direct and the reverse.Direct polarization occurs when the positive connection (+) is connected to the anode and the negative connection (-) to the cathode. On the other hand, the terminal (+) must ...
Electric currentsElectric currents are physical phenomena generated by the movement of the ion or electron. Direct electric current is the same as direct current, since, as its name suggests, it has a direct magnetization. The electric current is determined by OHM's law.I = V/RV = Voltage
MagnetostaticsMagnetostatics arises from the union of magneto + static. We first see it at the end of the 19th century by Arthur Gordon.Magnetostatics is the branch of physics that studies magnetic fields that remain fixed over time. Magnetostatics encompasses everything from magnets to electromagnets.There are different types of magnetostatics:
Atomic modelsAn atomic model is an atom, the smallest unit that makes up a chemical element. Depending on whether it has a positive, negative, or neutral charge, we can find protons, electrons, or neutrons.The atomic model was created as the years went by with the passing of historical moments and the knowledge provided by the ...
What is spectroscopy?Spectroscopy was discovered in 1666 by Isaac Newton who used the word spectrum to refer to all the colors that form part of the rainbow, which are obtained by passing light from the sun through a prism. Subsequently, this gave rise to spectroscopy, which is known as the study of the amount of light in ...
Gauss's lawGauss's law or also known as Gauss's theorem was discovered by Karl Friederich Gauss, a mathematician who formulated in 1835 the relationship found between the electric flux circulating on a closed surface which has an electric charge. It was not until 1869 that it was published.Gauss's law states that the electric field flux found on ...
