Fossils are the remains of living organisms, or of their biological activity, that have been preserved in sedimentary rocks. For a body or a sign of a body to become considered as a fossil it is needed that a physicochemical process known as fossilization takes place. Based on the idea that fossils are impressions of […]
The deoxyribonucleic acid or DNA is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms. This information is encoded by a sequence of four types of molecules called bases: adenine, thymine, cytosine and guanine. Is there any internal structure in the relationship between the descriptions […]
A city is a geographical space with high population density. In it there is a predominance of the tertiary and service sectors. It is a space of relationships, experiences and culture. Urbanism is the discipline that deals with the study of this space. A one-minute and three seconds video loop. It is a reconstruction of […]
The color of an object depends on its physical characteristics, on light and the perception of the observer. The primary colors in light are red, green and blue. The mixture of them in equal proportions gives white. All objects radiate white light that comes. They do not absorb energy or heat. This piece refers to […]
The scientific method is based on a set of techniques for investigating phenomena and acquiring knowledge. It starts from the collection of empirical, observable and measurable evidence. It proceeds by formulating questions and hypotheses and conducting experiments. It uses the principles of logical reasoning and has two pillars: reproducibility and falsifiabilty. We take as our […]
Lichens or lichenized fungi consist of two components or organisms living in symbiosis: one is the hyphae of a fungus (micobiont or micosimbiont) and the other are cells of an algae (gonidis, ficobiont or ficosimbiont ). They are indicators of pollution. Taking as point of departure the fact that lichens are bodies with a double […]
Pattern recognition, the identification of patterns or recognition of forms is a process of classification of samples into categories, using observed or measured data. It is the basis of many actions performed by living beings, this is why it is studied in fields like computer science, engineering or mathematics. The participants of the Science of […]
The atom is the smallest unit of a chemical element that still retains its same properties. It is made of subatomic particles: electrons, protons and neutrons. Protons and neutrons are made up of quarks. The atoms are grouped into molecules. A molecule is the smallest unit of a compound. Wave .. Where is Alice? I do not see her. Atom .. Yes, it was here, looking surprised to infinity. She gazed in an absent way, very distant, as if […]
Visible light is the portion of the electromagnetic spectrum that can be perceived by the human eye. It lies between the wavelengths of 380 nm and 780 nm in the air. Its basic features are brightness, color and polarization or angle of vibration. It presents properties of both a wave and a particle. The project […]
