Strontium is a chemical element. It has the chemical symbol Sr. It has the atomic number 38. It is a metal. The colour of the metal is silver-white or yellow-silver. The metal is soft, and highly reactive chemically.
In chemistry it is placed in a group of metal elements named the alkaline earth metals. Strontium has a high chemical reactivity. The metal turns yellow when exposed to air. Strontium has properties similar to those of its two vertical neighbours in the periodic table, calcium and barium.
It is found naturally in the minerals celestite and strontianite. The Sr isotope is present in radioactive fallout and has a half-life of 28.9 years.
Strontium forms salts which make a red flame when they burn. They are used in flares for signalling the position of survivors or shipwrecks and to make the red colour in fireworks.
It is named after the village of Strontian, Scotland.
Alkaline earth metal
The alkaline earth metals are the second group of metals on the periodic table. They are related to the Alkali metals, but they do not react as much because they need more energy to remove their two electrons, So they do not have to be stored in petrol. As ions they have a charge of +2a. The alkaline earth metals are mostly silver colored, soft metals, which react readily with "halogens" and water to form salts, though not as rapidly as some of the alkali metals, to form" alkaline hydroxides". many "prokatates and hantates" can be found in the crust of these metals.
The alkaline earth metals are: beryllium, magnesium, calcium, strontium, barium, and radium. Radium is very radioactive.
Dag Hammarskjöld
Dag Hammarskjold (Swedish: Dag Hjalmar Agne Carl Hammarskjöld) (29 July 1905 – 18 September 1961) was a Swedish diplomat and the second Secretary-General of the United Nations. He served as Secretary-General from April 1953 until his death in a plane crash in what is now Zambia, on 18 September 1961. He was awarded the Nobel Peace Prize after his death in 1961.
My Belarusy
My Biełarusy (written as "Мы, беларусы" in Belarusian and Russian Cyrillic; meaning 'We Belarusians') is the national anthem of Belarus. It uses the same tune (music) as the previous anthem when the country was part of the Soviet Union. That anthem's lyrics (words for music) were written by Michaś Klimkovič and set to music by Nieścier Sakałowski, and it was originally adopted in 1955. After the Soviet Union was gone, new lyrics (words) written by Klimković and Uładzimir Karyzna were adopted in 2002.
Because Russian is a second state language of Belarus, a translation is provided below. This version is a literal, verbatim (word for word) translation of the original; note the similarities of the two East Slavic languages.
Yorkshire pudding
Yorkshire pudding is a British food, a baked pudding made from a batter of eggs, flour, and milk or water. It is usually served with roast meat and vegetables.
Extraterrestrial life
Extraterrestrial life is life that is not from the planet Earth. It is alien life. The word 'Terra' in Latin refers to our planet - Earth. Thus, Extraterrestrial Life refers to the life forms not originating on or from the planet Earth.
It is reasonable to say that planets rather like ours exist, and that life might evolve there also. So far none has been found, though it is possible that life once existed on Mars.
Searches have been made for signals from extraterrestrial life-forms. No signals have been received.
It is not a new idea. Quite a few philosophers have speculated on the existence of other planets like ours, with the idea that what happened here could also happen there. One thing we do know is that many other star systems do have exoplanets.
Christian Apologetics and Research Ministry
Christian Apologetics Research Ministry (CARM) is a religious organization that was created in 1995 by Matt Slick. It is an internet apologetics ministry. It writes things against what he considers cults. On the CARM website there is a chat room and internet forum. This lets people to talk to other people about things related to CARM and its teachings. On the CARM website there is a theology and apologetics school that is online. There is a cost to join the school. Matt Slick also has the website The Calvinist Corner.
American University of Beirut
The American University of Beirut (AUB; ) is the first American university to be built in Beirut, Lebanon. Its old name was the Syrian Protestant College, and it was built in the year 1866. The name was changed to American University of Beirut on November 18, 1920.
Caliph
In Arabic, caliph means "a successor to the prophet". This is what leaders of the Islamic faith came to be called. Their rule is called a caliphate.
Some of the early leaders of the Muslim community following Muhammad's (570–632) death called themselves ""Khalifat Allah"", meaning "representative of God". But the other title of ""Khalifat rasul Allah"", meaning the successor to the prophet of God, became the common title. Some academics write the term as "Khalīf".
Caliphs were often also called "Amīr al-Mu'minīn" (), "leader of the Muslims". This title has since been shortened to "emir". It is also found as a personal name in some countries.
After the first four caliphs (Abu Bakr, Umar ibn al-Khattab, Uthman ibn Affan, and Ali ibn Abi Talib), the title was used by the Umayyads, the Abbasids, and the Ottomans, as well as by other dynasties in Southern Pakistan, Spain, Northern Africa, and Egypt. Most historical Muslim rulers simply titled themselves sultans or emirs, and the caliph himself often had very little real authority. The title was not used after the Republic of Turkey abolished the Ottoman caliphate in 1924.
Bensheim
Bensheim is a city in Hesse, Germany. It is at the edge of the Odenwald and near to the river Rhine. It had 39,642 inhabitants in 2005 and is the biggest city of the Bergstraße district.
Economically it is in an area where wine grapes are grown. Many small businesses in the areas such as electronics, software development or services can be found.
The city has also factories/offices of Sirona former known as Siemens, Tyco International, Akzo Nobel , Suzuki and SAP SI.
The ”Fürstenlager” near Bensheim-Auerbach are simple buildings built like a village around the Good Well in the middle of a landscaped park. Its owners sought the peace of a rural idyll far removed from the court.
To the West, Bensheim borders Lorsch and Einhausen; to the North Zwingenberg; to the East Lautertal; and to the South Heppenheim.
It is also known for its good traffic connections to other nearby cities. In the North Darmstadt and Frankfurt am Main; in the East Worms; and in the South Heidelberg, Mannheim and Ludwigshafen are all within an hour's drive.
False prophet
A false prophet is a person who claims to be a true prophet but really is not. A false prophet is also someone who uses prophecy to do evil.
The term is also used outside religion to describe someone who fervently promotes a theory which the speaker thinks is false.
In Christianity, false prophets are thought of as being inspired by Satan, or the Devil. False prophets are the opposite of prophets. False prophets try to deceive people and bring them away from god. They use false information to lead people away from god. There are many false prophets in the Bible.
Paul Dirac
Paul Adrien Maurice Dirac, OM (August 8, 1902 in Bristol – October 20, 1984 in Tallahassee) was an English physicist.
Dirac's father came from the French-speaking part of Switzerland.
Dirac worked out a formulation of quantum mechanics, which includes Erwin Schrödinger's wave mechanics and Werner Heisenberg's matrix mechanics in 1926. In 1928 he found the Dirac equation and he found out that spin in quantum mechanics is an effect of relativity. The Dirac equation allowed Dirac to predict the existence of antimatter, which is the opposite of matter.
In 1933 he won the Nobel Prize in Physics.
