  It presents the synthesis of the litteristics related to science *)

 

There are numerous publications that showcase diverse literature about science.

  I join with those who introduce some emotional aspects by avoiding the formalist style and tend towards metaphorical literature.

Something in addition to the encyclopaedic description goes without SF exaggeration

  Miraculous advances in science are gained, but the people who live there live on the isolated islands, dominated by their own specialty areas.

  Perhaps it would be a way of belonging to a less triumphalist climate than that of setting out the successes in the field of human mass destruction.

 

I try to exemplify it;

Professionally in optical systems I am impressed with the appearance and evolution of the eye.

From Wikipedia, the free encyclopedia:

Trilobites ( /ˈtraɪləˌbaɪt, ˈtrɪ-, -loʊ-/;[2][3] meaning "three lobes") are a fossil group ofextinct marine arachnomorph arthropods that form the class Trilobita. Trilobites form one of the earliest known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrianperiod (521 million years ago), and they flourished throughout the lower Paleozoicera before beginning a drawn-out decline to eEven the earliest trilobites had complex, compound eyes with lenses made of calcite (a characteristic of all trilobite eyes), confirming that the eyes of arthropods and probably other animals could have developed before the Cambrian.[20] Improving eyesight of both predator and prey in marine environments has been suggested as one of the evolutionary pressures furthering an apparent rapid development of new life forms during what is known as theCambrian Explosion.[81]

 Trilobites disappeared in the mass extinction at the end of the Permian about 252 million years ago. The trilobites were among the most successful of all early animals, roaming the oceans for over 270 million years.[4]

Trilobite eyes were typically compound, with each lens being an elongated prism.[82] The number of lenses in such an eye varied: some trilobites had only one, while some had thousands of lenses in a single eye. In compound eyes, the lenses were typically arranged hexagonally.[17] The fossil record of trilobite eyes is complete enough that their evolution can be studied through time, which compensates to some extent the lack of preservation of soft internal parts.[83]

Lenses of trilobites' eyes were made of calcite (calcium carbonate, CaCO3). Pure forms of calcite are transparent, and some trilobites used crystallographically oriented, clear calcite crystals to form each lens of each of their eyes.[84] Rigid calcite lenses would have been unable to accommodate to a change of focus like the soft lens in a human eye would; however, in some trilobites the calcite formed an internal doublet structure,[85] giving superb depth of field and minimal spherical aberration, according to optical principles discovered by French scientist René Descartes and Dutch physicist Christiaan Huygens in the 17th century.[82][85] A living species with similar lenses is the brittle star Ophiocoma wendtii.[86]

In other trilobites, with a Huygens interface apparently missing, a gradient index lens is invoked with the refractive index of the lens changing toward the center.[87]

Of course, in neophyte position, I can be in the attention of specialists

as an investigative test.

 

  It was then a somewhat ecological evolution, the eye evolving into both prey and predatory.

     The supreme command of survival is the reproduction as a dominant purpose, whatever the form of life has reached.

  Being for this must invent the most effective forms of defense and feeding.

 

Electromagnetic radiation existed and was chosen for the sensation of light,

  evolving towards organic elements that select less harmful, but sufficient, radiation to obtain satisfactory optical resolutions. (human eye situation).

Of course, specialists' exposures are edifying.

Biology and medicine have made miraculous progress

 

An attempt of me to find one of the probable survival vectors is described in the link:

 

Psychical satiety in affectivity

­_*) Scientific literature is the principal medium for communicating the results of scientific research and, as such, represents the permanent record of the collective achievements of the scientific community over time   …….

Scientific literature composing the scientific knowledge base is often divided into two basic categories:

  • Primary literature -- publications that report the results of original scientific research. These include journal papers, conference papers, monographic series, technical reports, theses, and dissertations.
  • Secondary literature -- publications that synthesize and condense what is known on specific topics. These include reviews, monographs, textbooks, treatises, handbooks, and manuals. These take time to produce and usually cite key "primary" publications on the topic.
