Chang was often in the Top 10 in the Association of Tennis Professionals world rankings for several years in the 1990s. His highest ranking (that is, the order in which it is shown how good he is in the sport at a certain time) was World No. 2.
When he won the French Open in 1989, Chang had a well known semi-final match with Ivan Lendl. Before the match, many people thought the unseeded Chang would lose to the No. 1 ranked Lendl. At first Chang was losing, but he won the important third set. Starting then, Chang began to have leg cramps, but won the match through determination. Today, many people remember this game as one of his best matches when the name Michael Chang is mentioned.
Chang was born in Hoboken, New Jersey, United States. His parents are Taiwanese. Chang is a Christian. With his family he started the Chang Family Foundation in 1999 "to introduce the Good News of Jesus Christ to the world".

Equus (genus)
Equus is a genus of mammals in the family Equidae. It includes horses, asses, and zebras. "Equus" is the only living (extant) genus of horses, and there are seven living species. They are the one-toed horses, and are adapted for living in various types of grasslands.
The term equine refers to any member of this genus. "Equus" has many extinct species known only from fossils. The genus most likely originated in North America and spread quickly to the Old World. Equines are odd-toed ungulates with slender legs, long heads, relatively long necks, manes (erect in most subspecies) and long tails. All species are herbivorous, and mostly grazers with simpler digestive systems than ruminants. They can live on low-quality vegetation.
Feral equine populations are widespread, but wild equines are found only in Africa and Asia. Wild populations may have a harem system. In this case one adult male or "stallion", several females or "mares" and their young or "foals". Otherwise they live in a territory where males control territories with resources that attract females. In both systems, females take care of the foals, though males may play a role as well. Equines communicate with each other visually and vocally. Human activities have threatened wild equine populations and out of the seven living species, only the plains zebra is still widespread and abundant.
The one-toed horses of the grasslands developed from smaller three-toed horses which lived more in forests and wooded savannahs. Before the coming of humans, horses were much more varied and widespread, though the number of species is not known.
There are seven species of living horses in the wild. They are:
"E. africanus"—African wild ass
"E. ferus"—wild horse
"E. grevyi"—Grévy's zebra
"E. hemionus"—onager
"E. kiang"—kiang
"E. quagga"—plains zebra
"E. zebra"—mountain zebra
This is not counting the many types of horse which mankind has modified by breeding. "Equus ferus" has been the species used by man as the basis of the various breeds of horse.
216 Kleopatra
216 Kleopatra is a Main belt asteroid found by Johann Palisa on April 10, 1880 in Pola. It is named after Cleopatra, the Queen of Egypt.
Kleopatra is an unusual object. Its odd shape was revealed by adaptive optics on the ESO 3.6m telescope at La Silla. By bouncing radar signals off the asteroid, a team of astronomers at the Arecibo radio telescope in Puerto Rico were able to develop a more detailed computer model of its shape, which confirmed the dog-bone like shape. A favored explanation is that Kleopatra is a contact binary: two similarly-sized asteroids that have hit and stuck together instead of breaking apart.
Kleopatra is a fairly big asteroid, measuring 217 × 94 × 81 km. It is believed to be a loosely packed metallic object, based on its radar albedo.
Ministry of Defence of Germany
The Federal Ministry of Defence (BMVg) is a Ministry of the Federal Republic of Germany. At present the headquarters of the ministry are still in Bonn with 3230 working in the Hardthöhe. The second office employs about 500 people in the Bendlerblock in Berlin.
The BMVg is at the highest Federal authority and the highest command authority of the defence forces. The BMVg has civilian and military departments:
Operatively the General Staff of the Defence Forces (or "FÜ S", which is short for ) is the most important, it has seven sections divided into 42 smaller sections
The press and information staff and the planning staff work directly under the minister
In peace time the Federal Minister of Defence is commander in chief of the Armed Forces, not the Federal President.
If Germany is attacked, or about to be attacked, command passes to the Chancellor.
In 1950 Chancellor Konrad Adenauer gave Theodor Blank the job of preparing for the time when Germany could have an army. In December 20 people where working in the "Blank Office". On 7 June 1955 it had 1300 employees, and it became the Federal Ministry for Defence.
It was renamed in Federal Ministry of defence on December 1961 and was seen as one of the "classic departments" . At German reunification the National People's Army (Nationale Volksarmee) of East Germany was made part of the Federal Armed Forces. Not long after this, Germany's army took part in the war in Kosovo. This was the first time that Germany's army had been sent to fight outside Germany since the end of World War II
Angstrom
An angstrom or ångström (symbol Å) is a unit of length that equals 0.1 nanometer (nm). It can be written in scientific notation as 1×10 m (normalized notation) or (exponential notation) — both mean . It is sometimes used to express the sizes of atoms, lengths of chemical bonds and visible-light spectra, and dimensions of parts of integrated circuits. For example, a single atom is about two ångströms wide, and a human hair is about a million ångströms thick.
The ångström is named after the Swedish physicist Anders Jonas Ångström (1814–1874), one of the founders of spectroscopy who is known also for studies of astrophysics, flow of heat, the earth's magnetic field, and the aurora borealis.
In 1868, Ångström created a spectrum chart of solar radiation that expresses each wavelength in the spectrum of sunlight in multiples of one ten-millionth of a millimetre, or 1 metres. This unit of length later became known as the ångström, Å.
Human beings can see light having wavelengths ranging from about 4,000 ångströms (violet) to 7,000 ångströms (deep red), so the ångström was a convenient unit of measurement. Because of its closeness to the scale of atoms and molecules it was also popular in chemistry and crystallography.
Today, the use of the ångström as a unit is less popular than it used to be, and the nanometre (nm) is often used instead (The ångström is officially discouraged by the International Committee for Weights and Measures, and by the American National Standard for Metric Practice.)
