After its discovery, the "new" element was named "ununquadium". The named changed on May 30th, 2012 to "flerovium". The International Union of Pure and Applied Chemistry named it so.
Not enough Flerovium has been made to measure its physical or chemical properties. It is thought that it would be a soft, dense metal that changes colour in air. It may have a low melting point of about 200 °C.
Flerovium can be made by bombarding a plutonium-244 target with calcium-48 as a beam of ions.
According to the nuclear shell model, the undiscovered neutron-rich nucleus Fl may be a doubly magic nucleus, atop the shell closure at N=184. It is predicted that this atom, amid the closed nuclear shells, expected to have longer half-lives for alpha decay and spontaneous fission. However using the fusion-evaporation method to produce this nuclide is impractical, since more neutron-rich starting materials with low proton numbers are unstable due to beta decay.
Estimates for half-lives for this atom range from a few minutes to several billion years.
Brontosaurus
Brontosaurus is a genus of sauropod dinosaur.
"Brontosaurus" was originally named by its discoverer Othniel Charles Marsh in 1879. "Brontosaurus" had long been considered a junior synonym of "Apatosaurus". Its only species was reclassified as "A. excelsus" in 1903.
However, an extensive study published in 2015 concluded that "Brontosaurus" was a valid genus of sauropod distinct from "Apatosaurus".
"Brontosaurus" is a member of the family Diplodocidae, a clade of gigantic sauropod dinosaurs. The family includes some of the longest creatures ever to walk the earth, including "Diplodocus", "Supersaurus", and "Barosaurus". "Brontosaurus" is closely related to "Apatosaurus" in the subfamily Apatosaurinae.
Fate
Fate or destiny is the idea that the future is already planned even if people do not know what their fate is (what is going to happen to them). Humans in nearly all cultures have had ideas about their fate being “predetermined” (fixed in advance).
People who live unhappy lives may believe that their misery is because of their fate and that they can do nothing about it. This is called being “fatalistic”. Other people may believe that they can control their fate by being brave and trying to “overcome” fate by improving themselves and their lives.
In Greek mythology there were three Fates. They were three goddesses who determined when every person was going to be born, how they would live and when and how they would die. Human beings in many cultures had lots of ways in which they would try to “read” their fate (know what would happen to them). Sometimes they would try to read their fate in the stars (this is called astrology). In other cultures they might ask a person with powers of magic like a shaman. The Ancient Greeks often went to Delphi to ask the oracle.
There are lots of references to fate in literature from almost every country and period, from Greek tragedy (e.g. Oedipus Rex) to Shakespeare (e.g. Macbeth) and Russian literature.
Composers may express fate in music. Beethoven was thinking about Fate when he wrote his Fifth Symphony, and Tchaikovsky when he wrote his Sixth Symphony just before he committed suicide.

August Heinrich Hoffmann (April 2, 1798 - January 19, 1874), who used Hoffmann von Fallersleben as his pen name, was a German poet. He is best known for writing "Das Lied der Deutschen", which is now the national anthem of Germany, and a number of popular children's songs.
Lake Peipus
Lake Peipus (Estonian: "Peipsi-Pihkva järv", German: "Peipussee", Russian: "Чудско-Псковское озеро") is a large fresh water lake. It is between Estonia and Russia in Northern Europe. Lake Peipus is the fourth largest lake in Europe. The lake covers 3,500 square kilometres. It has an average depth of 7m. At its deepest point, Lake Peipus is 15m deep. The lake is used for fishing and recreation.
Tanto
The Tantō is a Japanese short sword or dagger.
The tantō's traditional overall length was 11.93 in (1 shaku, about 30 cm). The blade's length was about 5in to 12in (12 1/2 cm to 30 cm). Blades that were bigger (13 to 14 inches) were called ko-wakizashi, meaning "small short sword." The tantōs which varied from the traditional size were called O-tantō or Sunobi tantō.
The tantō was a weapon with a single-edged blade and a curved shape. It was designed for soft targets and was thought to be a hidden weapon of the samurai. It was extremely effective in close fighting.
The tantō appeared during the Heian Period (795-1192 A.D.) and developed as a weapon during the Kamakura Period (1192-1333 A.D.). At that time the tantō was not just a weapon but also a work of art. It was richly decorated using the most spread styles: hira-tsukuri and uchi-sori. Later, in the Nambokucho period (1336-1392 A.D), tantōs become longer than 15.75 inches (37 cm). Blades become thinner and broader and thus even more dangerous. Different styles developed and the shape changed. During the Muromachi Period (1336–1573 A.D.) the tantō becomes once more narrow-bladed.
By this time the quality of the blade was better. It was the time when professional smiths appeared and there were several styles of tantō making. The best known smiths were: Sukesada and Norimitsu (Bizen-den); Kanemoto and Kanesada (Mino-den); Muramasa and Masashige (Ise). The beginning of Edo period (1603-1867 A.D.) was a period of relative peace after Japanese unification and, although not so many were made, they were of good quality. The heat treated blade's edge (hamon) becomes more waved and so more beautiful.
A great number of tantōs were made in the last 700 to 800 years. Some of them were for civil use. Others were made especially for samurai. One of the classifications is based on the hand guard type:
The most popular of the three tantōs were aikuchi and hamadashi. This was because of the fact that these two types had a small guard and they were easier to hide and carry. The tantō was not widely used on the battlefield, so the guard was mostly unnecessary.
Other styles of tantō differed by the shape of the blade. The best known are:
When the tantō was used on the battlefield it was supposed to go through the armor of the opponent when he was close. The best tantōs for this were those with a long, narrow blade and with a thick spine. The blow was applied with the point directed under or through the armor. The tantō was usually carried in a wide cloth belt (obi) with the edge up and the handle turned to the right. In the samurai house the tantō was often placed with the wakizashi (short sword). Samurai women were taught to use the tantō in case they needed to defend themselves or, if violated, to take their own life.
It is also considered that tantōs of different type were used for suicide ritual (seppuku, also hara-kiri). Still, it was mainly used by women samurai whose suicidal ritual was to cut their own throat. The men samurai had a different ritual: they used a wakizashi sword for disembowelment.
