When was longitude and latitude created?
3rd century BCE Eratosthenes in the 3rd century BCE first proposed a system of latitude and longitude for a map of the world.
What came first longitude or latitude?
latitude Handy tip: when giving a co-ordinate, latitude (north or south) always precedes longitude (east or west). Latitude and longitude are divided in degrees (°), minutes (') and seconds (“). There are 60 minutes in a degree and 60 seconds in a minute (similar to measuring time).
How was longitude discovered?
In the third century BCE, writer, geographer, astronomer, and poet Eratosthenes produced maps that included irregularly spaced grid lines which we would now call parallels (lines of latitude) and meridians (lines of longitude).
When was latitude first used?
The Phoenicians in 600 B.C. used the heavens to calculate latitude — as did the Polynesians in A.D. 400. Through the centuries, devices such as the gnomon and Arabian kamal were designed to measure the height of the sun and stars, and thereby determine the latitude.
How did John Harrison solve the longitude problem?
In order to solve the problem of Longitude, Harrison aimed to devise a portable clock which kept time to within three seconds a day. This would make it far more accurate than even the best watches of the time. John Harrison arrived in London, looking for both support and the rewards promised by the 1714 Longitude Act.
What did John Harrison invent?
Marine chronometerGrasshopp… escapementGridiron pendulum John Harrison/Inventions John Harrison, (born March 1693, Foulby, Yorkshire, Eng. —died March 24, 1776, London), English horologist who invented the first practical marine chronometer, which enabled navigators to compute accurately their longitude at sea.
Who invented time?
The Egyptians broke the period from sunrise to sunset into twelve equal parts, giving us the forerunner of today's hours. As a result, the Egyptian hour was not a constant length of time, as is the case today; rather, as one-twelfth of the daylight period, it varied with length of the day, and hence with the seasons.
How did sailors find longitude?
Sailors used a sextant to determine their latitudinal position. Longitude lines run vertically across the globe and are used to measure distances east and west of Greenwich, England. Determining longitude was very difficult for 18th century sailors.
Is Harrison’s clock accurate?
John Harrison was a carpenter by trade who was self-taught in clock making. During the mid-1720s he designed a series of remarkable precision longcase clocks. These clocks achieved an accuracy of one second in a month, far better than any clocks of the time.
Who invented clock?
Christiaan Huygens, however, is usually credited as the inventor. He determined the mathematical formula that related pendulum length to time (about 99.4 cm or 39.1 inches for the one second movement) and had the first pendulum-driven clock made.
Who created math?
Archimedes is known as the Father of Mathematics. Mathematics is one of the ancient sciences developed in time immemorial. A major topic of discussion regarding this particular field of science is about who is the father of mathematics.
Who invented zero in world?
"Zero and its operation are first defined by (Hindu astronomer and mathematician) Brahmagupta in 628," said Gobets. He developed a symbol for zero: a dot underneath numbers.

Who invented navigation?
The ancient Minoans, who lived on the Mediterranean island of Crete from 3000 to 1100 BCE, left records of using the stars to navigate, for instance. Compasses, which indicate direction relative to the Earth's magnetic poles, are used in navigation on land, at sea, and in the air.

Who invented paper?
Cai LunElmer L. GadenJohn Dickinson Paper/Inventors About 2,000 years ago, inventors in China took communication to the next level, crafting cloth sheets to record their drawings and writings. And paper, as we know it today, was born! Paper was first made in Lei-Yang, China by Ts'ai Lun, a Chinese court official.

Who invented 1?
Hindu-Arabic numerals, set of 10 symbols—1, 2, 3, 4, 5, 6, 7, 8, 9, 0—that represent numbers in the decimal number system. They originated in India in the 6th or 7th century and were introduced to Europe through the writings of Middle Eastern mathematicians, especially al-Khwarizmi and al-Kindi, about the 12th century.
What did Prince Henry discover?
In his first voyage, which started on 22 March 1455, he visited the Madeira Islands and the Canary Islands. On the second voyage, in 1456, Cadamosto became the first European to reach the Cape Verde Islands. António Noli later claimed the credit.

Who invented the compass?
China Historians think China may have been the first civilization to develop a magnetic compass that could be used for navigation. Chinese scientists may have developed navigational compasses as early as the 11th or 12th century. Western Europeans soon followed at the end of the 12th century.
