One of the most important activities of man in his ascent to culture has been the contemplation of the sky, and he has studied the position and movement of the stars even before becoming sedentary. Get to know in detail how the transparency of the sky is measured and enhanced.
MEXICAN SCIENCE AND INNOVATION
It is difficult to imagine our daily tasks, life itself, the Earth, the Cosmos without the light. Our daily activities and responsibilities depend more and more on the New Information and Communication Technologies whose basic functioning depends on the light; writing articles, tasks, and scanning the bar codes of the items we buy in shops and...
Like all inventions, the television responds to the curiosity of various characters, to the collective work in which a Mexican, a native of Guadalajara, stands out among them. His name - Guillermo González Camarena.
How important are crystals in the Universe, the planets, the Earth, life, and everything around us, including the arts and humanities? Crystallography is the main technique by which we can analyze the atomic structure of almost everything, while it is very useful to find out why things behave the way they do.
Working at temperatures close to the material's melting point and spinning hundreds of times per second, while carrying a load equivalent to the weight of a car, the turbine blades of a jet engine must withstand what is possibly one of the most extreme environments any engineered material could face.
The eye is a "capsule" that is basically filled with a liquid known as aqueous humor; when its drainage system becomes clogged, it builds up causing increased pressure inside, damaging the optic nerve. This is usually how glaucoma develops, an eye disease that causes gradual vision loss.
In the field of physics, a very interesting debate has grown up around the material existence of the phenomenon of time. The time we humans perceive also coincides with the tendency towards the disorder of all things, something that inevitably grows over time, as we adopt the most probable sets of objects and disordered configurations.
The decline in human activities due to the confinement has led to the recovery of nature and its expression in phenomena like bioluminescence, which has been observed along the Mexican coast in recent weeks, said David Uriel Hernández Becerril, a researcher at UNAM's Institute of Marine Sciences and Limnology (ICML).
Since prehistoric times, comets have caused fear and even panic because they were considered to carry bad omens. It is attributed to the fact that, unlike the Sun, the Moon, the planets and the stars, which follow regular patterns of movement in the celestial canopy, comets appear unexpectedly in any part of the sky showing variability in their...
