noble gas | Definition, Properties, Uses, & Facts | frikilife.comThe supposedly dense, waxy, red material was said to enable the process that has become synonymous with alchemy— chrysopoeia, the metamorphosis, or transmutation, of base metals such as lead into gold. Alchemists have often been dismissed as pseudoscientific charlatans but in many ways they paved the way for modern chemistry and medicine. The alchemists of the 16th and 17th centuries developed new experimental techniques, medicines and other chemical concoctions, such as pigments. The problem, Principe says, is that the alchemists did not yet know that lead and gold were different atomic elements—the periodic table was still hundreds of years away. Believing them to be hybrid compounds, and therefore amenable to chemical change in laboratory reactions, the alchemists pursued the dream of chrysopoeia to no avail. With the dawn of the atomic age in the 20th century, however, the transmutation of elements finally became possible.

From a conventional viewpoint programming is a process of command execution that brings about a certain result; a problem-solving tool to produce a desired outcome. Aside from its practical usage, coding is expanding to a different sphere of interpretation where new meanings gained, outgrow its primary function. My essay examines the role of non-function oriented programming, the artistic value of the concepts behind works of code and experimental programming languages. A work of code can acquire different forms and exist as an object, text or music piece gaining new definitions and material qualities. Designed for experience of thinking through them, esolangs unfold the confrontation of computer logic and human thinking in the most rational or the most absurd processes [ x ].

Programming language as a System of Thought Wednesday, January 18, by Medeina Musteikyte From a conventional viewpoint programming is a process of command execution that brings about a certain result; a problem-solving tool to produce a desired outcome.
Nuclear power is the use of nuclear reactions that release nuclear energy to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant. Nuclear power can be obtained from nuclear fission , nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium. Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators. Generating electricity from fusion power remains at the focus of international research. This article mostly deals with nuclear fission power for electricity generation. There are also 58 nuclear power reactors under construction and reactors planned, with a combined capacity of 63 GW and GW, respectively.

The noble gases are colourless, odourless, tasteless, nonflammable gases. They traditionally have been labeled Group 0 in the periodic table because for decades after their discovery it was believed that they could not bond to other atoms ; that is, that their atoms could not combine with those of other elements to form chemical compounds. Their electronic structures and the finding that some of them do indeed form compounds has led to the more appropriate designation , Group When the members of the group were discovered and identified, they were thought to be exceedingly rare, as well as chemically inert, and therefore were called the rare or inert gases. It is now known, however, that several of these elements are quite abundant on Earth and in the rest of the universe , so the designation rare is misleading.
