Topic: Millikan Oil-Drop Experiment The Millikan Oil-Drop experiment was the first experiment to determine the charge of an electron. In 1909‚ Robert Millikan ultimately came up with a way to determine this charge through finding the minute electric charge on a droplet from an oil mist. Basically‚ Millikan started with an enclosed chamber that had two flat plates inside‚ one with a positive charge and one with a negative charge. The portion is split up by the positively charged plate so at the beginning

The printing press was transformed by Johann Gutenberg‚ a German goldsmith‚ and more than 8 million books were printed in Western Europe between 1456 and 1500. This invention had an effect with the Protestant Reformation. It not only furthered the knowledge of geography‚ but it also expanded knowledge throughout the countries and whether you were wealthy or poor‚ printing made books available to the general public. By 1560‚ many people were either Catholic‚ Protestant‚ or mixed (Doc. 5). Non-Catholic

The Golden Ratio By : Kaavya.K In mathematics and the arts‚ two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one. The golden ratio is an irrational mathematical constant‚ approximately 1.6180339887. Other names frequently used for the golden ratio are the golden section and golden mean. Other terms encountered include extreme and mean ratio‚ medial section‚ divine

model started to emerge. Johannes Kepler‚ a German mathematician‚ astronomer‚ and astrologer‚ became one of the more popular supporters of Galileo and his discoveries. He is most famous for his Laws of Planetary motion‚ which detail how planets move in space. According to his first law‚ planets moved in and elliptical motion around the Sun. He noticed this in his observations of Mars‚ where predictions in its where it was supposed to be in the sky were inaccurate. This led Kepler to determine that planets

He also noticed that stars in the Milky Way are packed densely together. In 1611‚ Johannes Kepler decided to change the design of the telescope by using two convex lenses. The downside to this method is

SEMRA ÖZAL THE HISTORY OF LOGARITHMS John Napier is a Scottish mathematician who lived from 1550 to 1617. He worked more than twenty years to improve his theory and tables of what he called logarithms. Napier called the theory logarithms‚ because he thought of them as “reckoning numbers”‚ namely to calculate an amount(Caulfield 2010). “The word he derived from two Greek roots: logos meaning word‚ or study‚ or reasoning‚ or in Napier’s use “reckoning”
