Astrolabes During The Age Of Exploration

Ancient Greek astronomers made some amazing mathematical and philosophical discovers about our universe. From the Hellenistic Greek observations in approximately 300 B.C.E., to the invention of the first telescope in the seventeenth century, to the launching of today’s space probes, one thing is evident: astrological observations are imperative to creating a calendar.

Astrolabe – a complex type of inclinometer in the shape of a sphere or large circle used to chart the positions of stars, planets, moon and Sun, which could then be used to estimate location (use triangulation) and time. Originally invented around 150 B.C., it was greatly developed in the Islamic world. Similar, the marine astrolabe, a large disc shaped instrument used for navigation while at sea.

Have you ever wondered where some of the things we use every day come from? Well, everything around us from the roads, the calendars, to the columns on the White House are ancient inventions that we use everyday. Ancient civilizations from the Eastern Hemisphere have invented these items. Some of the inventions that they made change our daily lives. Three inventions that impact our lives today are architecture, the calendar, and the roads invented by Romans.

Hipparchus was a greek astronomer, geographer, and mathematician born 190 B.C. in Nicaea and died in 120 B.C. Rhodes, Rhodes, Greece. Hipparchus is accredited as the inventor of trigonometry because of his discovery of the first table of chords and also because he's the only person with valid data of the discovery and usage of trigonometry. In order to calculate the rising and setting of zodiacal signs, Hipparchus brought to light the division of circles into 360 degrees and the calculation of chords by looking at the triangles (spherical triangles or triangles that made up a circle) differently. Hipparchus experimented putting all triangles to be within a circle and with the three points each touching the

In the 1500’s to 1600’s sailors made a big discovery in the line of navigation of latitude which is the art of directing vessels on the open sea. The inventor John hadley invented the Sextant which is a device that finds the angle between astronomical object and the horizon for the purpose of celestial navigation. The angle when measured can be used to calculate a position line on nautical or aeronautical chart. A common use of the sextant is the sighting of the sun or the solar moon in the northern hemisphere of the world to determine the latitude. it would be hard if the sailors did not have a sextant or if the moon was not out at that night. Or if your math was not right because if you had one little miscalculation your latitude could be

While researching “pre-industrial astronomical accomplishments,” it seemed that a good majority of the accomplishments being highlighted were those of the Mayan and Aztec civilizations. Feeling that these topics may be over-researched, I decided to turn my attention towards the accomplishments of those in a different area of the world. After switching my focus to the pre-industrial astronomical feats of ancient Greek scientists, I have found that in many cases, these scientists contributed more than one idea, finding, or apparatus to the field of astronomy. For this research, I decided to hone in on the contributions made by Greek scientist Hipparchus. Throughout his magnificent life, and all before the implementation of modern technology,

They were important because from then and today people need to use it to do science and other daily stuff that they need to do. He also was very important to the world because if people didn't know the three laws of motion today we basically wouldn't be able to do science because that is how important he was he mad basically science because he was so smart.

Most of these items are related to the study of heavenly bodies and the subject of astronomy. The Celestial globe is used to observe the positions of the stars and other celestial bodies. The Two Quadrant are used to read time, it allows the height of the sun and the angle to the horizon to be calculated. A sundial is an instrument used to measures apparent solar time, by measuring the position of the shadow of the sun as it changes through the day. The Torquetum is an object used to determine the relative position of heavenly bodies and tell the time. According to the experts, the sundials reveal that it is 10:30 am on April 11,1533. This tells us that exact date and time of Dinteville?fs visit to London.

rudimentary ideas about geometry and other mathematical evidences we know to be true. Ancient Greeks built some of the first planetary models while studying astronomy and trying to both understand and explain the universe and all it contains (khanacademy.org).

He also invented machinery to replace manual work of man, such as his water pumps and locks which saved the cities of Florence and Venice from floods. His achievement still stands today, we now have dams that can be opened and closed which allow water to be emptied when they're full.

The first wonderful invention is mathematics which they created base 60 or sexageismal which was used to help form the 360 degree circle and made it so that they can easily trade and make a living. They learned math but only the wealthy students of the priests who were teachers and believed to be the only links to God.

Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, and astrological practices of pre-history: vestiges of these are still found in astrology, a discipline long interwoven with public and governmental astronomy, and not completely disentangled from it until a few centuries ago in the Western World . In some cultures astronomical data was used for astrological prognostication.

The Age of Exploration had a lot of technological advances that helped them launch. For example, the Carvel was a ship that had many uses. These ships were from small to medium. There were two more things that helped them out and they had an explorer ship, which that helped all of the explorers travel and helped them get place to place.

The solar system was created 4.6 billion years ago by a gravitational collapse. A solar system is a star that has planets, moons, asteroids, comets, and meteoroids travel around it. The solar system contains eight known planets which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, and Neptune. There is around several hundred dwarf plants but only five are currently recognized. The solar system has about 181 moons which orbit around the planets in the solar system. There is also about 150 million asteroids and 3,406 comets also in the solar system.

According to Victor Katz in “A History of Mathematics (3rd Edition)” (Pearson, 2008), trigonometry developed primarily from the needs of Greek and Indian astronomers. But today, trigonometry and geometry were used on various fields such as: architecture, physical sciences, engineering, astronomers, medical imaging (CAT scans and ultrasounds), etc.
