Dava Sobel’s novel, Longitude: The True Story Of A Lone Genius Who Solved The Greatest Scientific Problem Of His Time is a history of the scientific battle to obtain a method of finding the exact longitude of a specific location. Knowing the longitude of a location may seem unimportant, but in fact it is vital. To fully understand the work that went into this effort, first, one must understand the basic principles for determining location on Earth. Latitude is used to measure the distance north or south of the equator. Longitude is used to measure the distance east and west of the prime meridian. Latitude can simply be measured by measuring the height of the sun. The process of determining longitude is a much more complicated matter. One reason …show more content…
The sudden loss of all these men led to the British Parliament passing the Longitude Act of 1714. The parliament offered a prize of 20,000 pounds to anyone who could have brought them a “practical and useful” way of determining longitude. A panel of judges known as the Board of Longitude was given the task of finding the best fix to the problem and awarding the winner the money. There was a widespread belief that longitude would be able to be determined by the use of celestial objects. As a result of this King Charles built the Royal Observatory in Greenwich. John Flamsteed was put in charge of the observatory and given the title as Royal Astronomer. People also looked at timekeeping as a way to determine longitude, but it was not reliable at the time because the clocks on ships were not precise because of the changing conditions that occurred. Scientist throughout the world worked on many unconventional ways to try to determine longitude for example, putting a special powder on a dog so it would bark at certain …show more content…
Graham gave Harrison a loan that Harrison used to fund the building of his first sea clock. Harrison called his clock Harrison’s number 1 or H-1 for short. To test the clock it was put aboard the H.M.S. Centurion, which was headed for Lisbon. The Board of Longitude convened for the first time ever to discuss the H-1. Harrison asked the board for funds that would allow him to fix the flaws of the H-1. Before, Testing the H-2 he asked for funds to create the H-3 which would once again fix the flaws of the previous
In papal Rome in the early 16th century the “Good Book” was the reference book for all scientists. If a theory was supported in its holy pages, or at the very least not contradicted, then the idea had a chance of find acceptance outside the laboratory. Likewise, no theory no matter how well documented could be viewed with anything but disdain if it contradicted with the written word of, or the Church’s official interpretation of scripture. For these reasons the Church suppressed helio-centric thinking to the point of making it a hiss and a byword. However, this did not keep brave men from exploring scientific reason outside the canonical doctrine of the papal throne, sometimes at the risk of losing their own lives. While the Vatican was able to control the universities and even most of the professors, it could not control the mind of one man known to the modern world as Galileo Galilei. Despite a wide array of enemies, Galileo embarked on a quest, it seems almost from the beginning of his academic career, to defend the Copernican idea of a helio-centric universe by challenging the authority of the church in matters of science. Galileo‘s willingness to stand up for what he held to be right in the face of opposition from Bible-driven science advocates set him apart as one of the key players in the movement to separate Church authority from scientific discovery, and consequently paved the way for future scientific achievement.
Galileo Galilei (Physicist, Scientist, Mathematician) – He is the 7th most influential people in history. He was often called as Galileo and was born on February 15, 1564 in Pisa, Dutche of Florence, Italy. Galileo is an Italian physicist, engineer, astronomer, mathematician and philosopher. During the Renaissance Period, he played an important part on the scientific revolution. He is called as the Father of Physics, Science and Observational Astronomy. Galileo’s father was named Vicenzo Galilei who was a composer, music theorist and a lutenist. And his mother was named Giulia Ammannati.
After reading this letter I feel that Galileo had a very opinionated outlook on life and was heavily involved in a struggle for freedom of inquiry. Galileo was a person who had many strong beliefs and would not let people or a document have a say in what he believes.
Until Copernicus, the teachings of the Greek astronomer Ptolemy were considered the indisputable truth. His idea was that the Earth was the stationary center of the universe. The sun, moon, planets, and th...
Although there is much debate about Magellan and his crew, facts show that Magellan achieved great success and he proved that the world could be navigated by sea. He successfully routed and crossed the Strait of Magellan even though it was unknown to Europeans and despite the various obstacles (Doc. C). In total, the voyage of Magellan took three years, and although Magellan never returned to Spain, he discovered the route to Asia through the Western Hemisphere which opened up trade and expanded European knowledge about the
Celsius is considered to be the first astronomer to analyze the earth's magnetic field. He analyzed this at the time he analyzed the norther light and he assessed the brightness of the stars with his measuring tools. At the observatory Celsius favored the work of the temperature scale. The scale of a mercury thermometer at an air pressure of 760 mm of mercury into 100 degrees celsius. This is where 100 was taken as the freezing point of 0. By favoring the temperature scale celsius started making observations. As a result of his testing he came up with the centigrade scale.
Christopher Columbus was known as a “dead reckoning navigator”[2]. Dead Reckoning Navigation, or also known as Deduced Navigation, was used by an umpteen of sailors. In Dead Reckoning Navigation the helmsman can find his locus by measuring the distance he has sailed to a known point. Each day, the ending position was the starting point for the next day. However, this method is not as elementary as it sounds. In order for this tactic to work, the helmsman needs to measure his course and distance sailed. Therefore, a course is measured by a magnetic compass, and distance with a time and speed calculation. One can conclude then that this was a nettlesome process. Of course, since then humans have immensely improved in this area. Today, there is a way to know where one is at while at sea that is much less problematic.
Christopher Columbus is a name that has been spoken in every history class across the nation. He is known as one of the most important sailors in history. Columbus primarily sailed by using a type of navigation known as “Dead Reckoning”. Dead Reckoning is a type of navigation in which a sailor marks his or her position by recording the distance sailed and by starting at a known point (Pickering, Keith A. “Columbus and Dead Reckoning (DR) Navigation” The Columbus Navigation Homepage). Though he used dead reckoning most of the time, he did occasionally use celestial navigation. Celestial Navigation is when a sailor uses celestial bodies such as the stars and the planets to navigate and measure his latitude, because Columbus had visited several other lands where new navigation techniques were being discovered he was a little more familiar with them than other sailors in his era were. (Pickering, Keith A. “Columbus and Celestial Navigation” The Columbus Navigation Homepage) Columbus used a variety of different tools to try and navigate with celestial navigation. Two of the tools he used were the quadrant and the astrolabe. After several attempts with both of the devices, however, he was still unsuccessful with all of his attempts.

A key parallel between the scientific revolution and the enlightenment was the decreasing belief in authority. The scientific revolution lead to great advances in astronomy, mathematics, geography, botany and medicine (7). A key discovery was that of Copernicus’ heliocentric theory (2). The heliocentric theory proposed that the sun was at the centre of the universe as opposed to the earth which was the common belief held strongly at the time. Copernicus discovered that the sun was at the centre of the universe, and that the moon orbited the earth while the earth orbited the sun. This theory raised profound qu...
The purpose of this paper is to describe the life and the contribution to the development of the British Empire of one of the most important English explorers. It was in the second half of the 18th century when James Cook, originally a poor farm boy, explored and mapped vast uncharted areas of the Pacific and the Atlantic Ocean. However, James Cook was not ‘only’ an explorer. He can also be called a scientist – he managed to introduce new principles into seafaring and cartography.
Prior to the European Renaissance, sailors could not determine the longitude
Galileo Galilei was born on February 15, 1564, in Pisa, Italy. He was a mathematics professor who made pioneering observations of nature with long-lasting implications for the study of physics. Galileo constructed a machine that changed everything in astronomy, the telescope, and this supported the Copernican theory. In 1600, Galileo met Marina Gamba, a Venetian woman, who gave him three children. The daughters were Virginia and Livia, and son Vincenzo. But He never married Marina because he feared his illegitimate children would threaten his social standing. He died in Arcetri, Italy, on January 8, 1642.
Earth, the world we live in today, as everyone knows and acknowledges for granted is spherical or round. However, this indisputable fact was not entirely considered the truth by many of the great philosophers and thinkers of the 16th century, who believed that the earth was flat or quadrilateral. For the majority of people, it would have taken a physical form of evidence to convert their beliefs. Therefore, this evidence was proved by the Portuguese explorer, Ferdinand Magellan.
Galileo was probably the greatest astronomer, mathematician and scientist of his time. In fact his work has been very important in many scientific advances even to this day.
The Global Positioning System, more commonly called the GPS is a satellite based system that provides navigation for almost everything from cell phones to automobiles. This wonderful technology is very vital in today’s economy because of its prominence in banking, financial markets, power grids, farming, construction and so much more. It also protects human life by preventing accidents, helping in search and rescue missions and is critical to nearly every facet of military operations. There are three segments that make up the global positioning system: the space segment, the control segment and the user segment. The segment we are familiar with is the user segment. The user segment is what receives GPS signals, determines the distance between a satellite and a receiver and solves the navigation equations, all in order to obtain the coordinates of a specific place. The space segment consists of 31 satellites but there is an availability of at least 24 satellites that are approximately 6 000-12 000 miles above the earth.
