Zip
A zip, also known as a zipper or zip fastener is a device for binding the edges of an opening of fabric or other flexible material. It is used mostly to hold clothes together. The zip can also be used for fastening luggage, bags, sporting goods and camping gear (e.g. tents and sleeping bags).
Elias Howe, the inventor of the sewing machine, also received a patent for an "Automatic, Continuous Clothing Closure" on April 29, 1851. This invention was an early version of what we now know as the zipper and was designed to be used as a fastening device on clothing and other textile products. However, despite receiving the patent, Howe never attempted to market his invention and the idea of the zipper was later developed by other inventors.

ETYMOLOGY
The word zip originally referred to the sharp sound of a fast-moving object such as a mosquito (first recorded in 1875) or a bullet (1885).
The term zip-fastener was first seen in 1927 in the Daily Express.
The first use of the verb 'to zip' in the sense of doing up a zip, was in Aldous Huxley's 1932 novel Brave New World

Zimbabwe
Zimbabwe is a landlocked plateau country in the southern part of the continent of Africa. It has a land area three times the size of England.
Zimbabwe is thought to be the location of Ophir, the Biblical land from which King Solomon got gold, ivory, peacocks and other precious items.
The first people in Zimbabwe were the Bantu-speaking Iron Age farmers that settled before 380 AD.
HISTORY
Zimbabwe is thought to be the location of Ophir, the Biblical land from which King Solomon got gold, ivory, peacocks and other precious items.
The first people in Zimbabwe were the Bantu-speaking Iron Age farmers that settled before 380 AD.
The name of Zimbabwe comes from the ancient ruined city of Great Zimbabwe in the south-eastern hills of Zimbabwe near Lake Mutirikwi. It means “great house of stones” in the local Chishona language.
Great Zimbabwe is thought to have been the capital of a great kingdom, although which kingdom is not certain, during the country's Late Iron Age. Construction on the city began in the 9th century and continued until it was abandoned in the 15th century.
The ruins of Great Zimbabwe were constructed with geometric precision instead of mortar and had religious sculptures matching the sophistication of other medieval civilizations. Chinese and Persian artifacts found at the site also prove they had far-reaching trade networks.
By 1200 Mashonaland, now East Zimbabwe, was an important settlement of the Shona people, who had moved from the North and erected stone buildings.
In the 15th century the Shona empire, under Mutota, expanded across Zimbabwe before it fell to the Rozwi, who ruled until the 19th century.
In 1837 the Matabele, a Bantu people, in retreat after unsuccessful battles with the Boersi, settled in Western Zimbabwe.

Harare, the capital of Zimbabwe, was founded on September 12, 1890 by the Pioneer Column, a small military force of the British South Africa Company. It was originally named Fort Salisbury after the British Prime Minister Lord Salisbury. The city was renamed Harare in 1982, after the Shona chief Neharawa.
Mashonaland and Matabeleland, together with what is now Zambia, were granted to the British South Africa company in 1889, and the whole was named Rhodesia in 1895, in honor of Cecil Rhodes.
King Lobengula of Matabeleland accepted British protection in 1888 but rebelled in 1893; he was defeated, but in 1896 after the Jameson Raid the Matabele once more unsuccessfully tried to regain their independence.
Their portion of the area south of the Zambezi river, then known as Southern Rhodesia, became self-governing in 1923 and a member of the Federation of Rhodesia and Nyasaland in 1953.
African nationalists were campaigning for democracy and the African National Congress (ANC), which had been present since 1934, was reconvened in 1957 under the leadership of Joshua Nkomo. It was banned in 1959 and in 1961 Nkomo created the Zimbabwe African people's Union (ZAPU). In 1963 a splinter group developed from ZAPU, the Zimbabwe African National Union (ZANU) with Robert Mugabe as its secretary-general.
After the dissolution of the Federation of Rhodesia and Nyasaland in 1963 the leader of the Rhodesian Front party (RF) Winston Field, became the first prime minister of Rhodesia. The RF was a grouping of white politicians committed to maintaining racial segregation.
In April 1964 Field resigned and was replaced by Ian Smith. Rhodesia's Unilateral Declaration of Independence was adopted by the mostly white minority government of Prime Minister Ian Smith on November 11, 1965. It announced that the British colony of Rhodesia, self-governed since 1923, regarded itself as a sovereign state. The culmination of a protracted dispute between the British and Rhodesian governments, it was the first unilateral breakaway by a British colony since the United States Declaration of Independence in 1776.
Britain broke off diplomatic and trading links with Rhodesia and the United Nations initiated economic sanctions, but these were bypassed by many multinational companies.
In 1969 Rhodesia declared itself a republic breaking its last links with the British crown. It adopted a new constitution, with white majority representation in a chamber legislature. Rhodesia continued as an unrecognised state for the next decade.
At the beginning of 1979 Smith produced a new majority rule constitution, which contained an inbuilt protection for a white minority but which he had managed to get Bishop Muzorewa to accept. In June 1979 Bishop Muzorewa was pronounced prime minister of what was to be called Zimbabwe Rhodesia. The new constitution was denounced by Mugabe and Nkomo. By now, they were leading the Zimbabwe African National Liberation Army from bases in neighbouring Mozambique.
In September 1979 the Lancaster House agreement paved the way for full independence. A new constitution was adopted and elections were held under independency profession in February 1980. They resulted in a decisive win for Robert Mugabe's Zimbabwe African National Union – Patriotic Front party.
The new state of Zimbabwe became fully independent on April 18, 1980, with the Rev Canaan Banana as the country's first President and Robert Mugabe as Prime Minister. The Zimbabwe Dollar replaced the Rhodesian Dollar as the official currency.
The national flag of Zimbabwe consists of seven even horizontal stripes of green, gold, red and black with a white triangle containing a red 5-pointed star with a Zimbabwe Bird. The present design was adopted on April 18, 1980. It is based on the flag of Zimbabwe's ruling party, the Zanu-PF.
Robert Mugabe was the President of Zimbabwe from 1987 until his resignation in 2017.
Zimbabwe's commercial farming sector was traditionally a source of exports and foreign exchange, and provided 400,000 jobs. However, the government's land reform program badly damaged the sector. Coffee production, once a prized export commodity came to a virtual halt after seizure or expropriation of white-owned coffee farms in 2000, and has never recovered.
The Zimbabwe dollar was abandoned as its national currency on April 12, 2009 after hyperinflation had led to an inflation rate of 79.6 billion per cent. The country has since been using the U.S. Dollar, the South African Rand, and the Botswana Pula.
In 2013, the finance minister of Zimbabwe announced that after paying its civil servants that month, the country would have just £138 ($217) in its state bank account.
When Shimon Peres stepped down as Israel’s president in July 2014, President Robert Mugabe (born February 21, 1924) assumed the mantle of the world’s oldest head of state.
On November 15, 2017, President Robert Mugabe was placed under house arrest as Zimbabwe's military took control in a coup. He resigned the Presidency a week later.

Zero
Zero is the point when reckoning begins. In mathematics it is a number meaning nothing.
Records show that the ancient Greeks seemed unsure about the status of zero as a number. They asked themselves, "If you don't have anything, why do you need a number?", leading to philosophical arguments about the nature and existence of zero.
The Mayan civilisation constructed quite early a very sophisticated number system, possibly more advanced than any other in the world at the time. It included one of the earliest instances of the explicit zero in the world, which they represented as a shell shape.
The concept of zero as a digit in the decimal place value notation was developed in India, The earliest text to use a decimal place-value system, including a zero, was the Lokavibhāga, a Jain text from the mid fifth century.
In the Medieval period there were religious arguments about the nature and existence of zero. Zero and negative numbers were banned in Florence in the 13th century because they were considered a thing of the devil.
Although mathematicians have used zero since at least the 8th century, the word 'zero' was first recorded in English only in 1604.
When he published his equations of general relativity Albert Einstein failed to notice that his theory predicted an expanding universe. Alexander Friedmann, a Russian mathematician, found to his amazement Einstein had made an elementary algebraic error that caused him to overlook a solution to his own equations. Einstein had divided by zero at one point in his calculations, a mathematical impossibility.
Humans are unable to burp in zero gravity environments.
Honeybees, despite having the brain size of a sesame seed, can understand the concept of zero.
In English, zero quantities are plural by default. Therefore you shall write "0 results found", "I have found no results".

Zeppelin
A Zeppelin is a type of rigid airship, which was named after the German Count Ferdinand von Zeppelin (July 8, 1838 – March 8, 1917).
On retiring from the army in 1891, von Zeppelin devoted himself to the study of aeronautics, and his first airship was built and tested in 1900.
Von Zeppelin’s first rigid airship, the LZ-1, made its maiden flight over Lake Constance near Friedrichshafen, Germany on July 2, 1900. The Zeppelin airship had an engine and a propeller which meant the aircraft could be directed.
Zeppelins were originally used for public transport. They were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights.
During World War I, a number of Zeppelin airships were employed in bombing England. Great Yarmouth was the first British town to be bombed by a Zeppelin, on January 19, 1915. London suffered its first raid on May 31 of that year.
The most intense of all the Zeppelin attacks during World War I was on September 2, 1916, when fourteen Zeppelins dropped 35,000 lb. of bombs on London and elsewhere.
Cow intestines used for sausage skins were so vital in making gas bags for German Zeppelins that during World War 1 the Kaiser banned Germans from eating sausages.
The German LZ 127 Graf Zeppelin became the first commercial passenger transatlantic flight service in 1928. The hydrogen-filled airship was named after Ferdinand von Zeppelin.
The Hindenburg and Graf Zeppelin II airships were the largest aircraft (in terms of length and volume) to take to the skies. Built in Germany between 1932 and 1938, each was 245m (803ft) long.
The Hindenburg airship caught fire and was destroyed while trying to land at Lakehurst Naval Air Station in New Jersey, killing over 30 people on board.
The Hindenburg Zeppelin, named after the late German president Paul von Hindenburg, was almost named Hitler but was refused by Adolf due to his dislike of large aircrafts. He later said he was glad the aircraft didn't share his name after the famous Hindenburg Disaster of 1937.
The Hindenburg disaster in 1937, along with political and economic issues, hastened the demise of Zeppelins. Sometimes, they are still used as tourist attractions, or for advertising.
The rock band Led Zeppelin got their name from a fellow musician, who predicted the group would go down like a "lead balloon."
When Led Zeppelin played together for the first time in front of a live audience in Gladsaxe, Denmark, in 1968, they used the name 'The Nobs'. This was because Eva von Zeppelin, granddaughter of the inventor of Zeppelin airships, threatened to sue them for tarnishing the family name.

On retiring from the army in 1891, von Zeppelin devoted himself to the study of aeronautics, and his first airship was built and tested in 1900.
Von Zeppelin’s first rigid airship, the LZ-1, made its maiden flight over Lake Constance near Friedrichshafen, Germany on July 2, 1900. The Zeppelin airship had an engine and a propeller which meant the aircraft could be directed.

Zeppelins were originally used for public transport. They were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights.
During World War I, a number of Zeppelin airships were employed in bombing England. Great Yarmouth was the first British town to be bombed by a Zeppelin, on January 19, 1915. London suffered its first raid on May 31 of that year.
The most intense of all the Zeppelin attacks during World War I was on September 2, 1916, when fourteen Zeppelins dropped 35,000 lb. of bombs on London and elsewhere.
Cow intestines used for sausage skins were so vital in making gas bags for German Zeppelins that during World War 1 the Kaiser banned Germans from eating sausages.
