Factual Sciences

The factual or factual sciences are those that deal with the factual (de factum, the Latin word for “facts”) or tangible verification of their hypotheses and premises, based on observation and experimentation, that is, the reproduction of a series of conditions to obtain a predictable result. For this reason, they depend on empirical content that must be confirmed through experience: such verifiability […]

Science and Technology

In the contemporary world, it is common to refer to science and technology as almost synonymous, given that the relationship between the two is extremely close and that their combined effect has allowed us to modify the world at our whim, especially after the so-called Technological Revolution from the end of the 20th century. However, these are separate disciplines, […]

Metals and Non Metals

All known matter is made up of atoms, from the 112 chemical elements that make up the periodic table. These elements are classified, according to their nature and properties, into metals and nonmetals. Only 25 of the 112 elements are metallic, generally coming from minerals and with properties and electrical interactions thoroughly studied by inorganic chemistry. Instead, the rest of the elements, non-metallic, are […]

Difference between Resolution and Magnification

Resolution and magnification are two terms used in Optics which are related to each other. The Basic difference between resolution and magnification is that Resolution is the ability to separate two closely placed objects while magnification is the mean of increasing the size of the object. Resolution Vs Magnification Resolution Magnification 1. Resolution is the […]

Gram Positive And Gram Negative Bacteria

The bacterial recognition and classification method by Gram’s Tincture was invented by the Danish scientist Christian Gram in 1884 and from there derives its name. What does it consist of? It consists of adding a specific series of pigments and mordants to a laboratory sample, thus achieving a pink or violet staining, depending on the type of bacteria: Gram-positive […]

The Chemical Bases

A chemical base is all that substance that when dissolved releases hydroxyl ions (OH – ). Chemical bases are also known as alkalis, because as the hydroxyl groups dissociate and release, the pH of the solutions increases, that is, the solution becomes alkaline. This is contrary to what happens when acid dissolves because in that case the pH decreases and the solution becomes acidic. The bases have a characteristic […]

20 Examples of Hydrocarbons

The hydrocarbons are organic compounds consisting exclusively of a shell of atoms of hydrogen and carbon, which are the basis of all organic chemistry. The structure of said atomic frameworks can be linear or branched, open or closed, and depending on their arrangement and number of components, it will be a question of one or another substance. The hydrocarbons are flammable […]

Examples Of Fossil Fuels

The fossil fuels are those that originated the mass of organic matter (biomass) produced million years ago and buried in the inner layers of the subsoil, where pressure, temperature and other physical and chemical processes she underwent deep transformation processes the result of which is, precisely, substances with enormous energy content. Fossil fuels are non-renewable energy sources, as they are currently […]

Write The Types And Examples Of Biodiversity

Biodiversity is the name given to the variety of life forms that develop in a natural environment. All plants, animals, microorganisms, as well as the genetic material of each one of them, are included in the definition. The species that inhabit the region are important as well as the ecological function that each one fulfills, which in some […]

10 Examples Of Natural Disasters

There is talk of natural disasters to refer to major traumatic events for human society, the effects of which are linked to natural phenomena and even those derived from certain human activities, such as in the case of major industrial pollution. The cost of natural disasters usually implies the numerous loss of life, human and animal, as well as the […]
