What is Aristotle's main philosophy?

OK, so I looked in my history book and it said that he thought people should live life based on reason, or clear and ordered thinking. Hope this is helpful for anyone who needs it. :)

What did Archimedes contribute to math?

he invented calculus, found the value of pi, solved the problem of buoyancy, established the law of the lever, defined the spiral, used the method of exhaustion to calculate the area of the arc of a parabola (dno wat that is), found an ingenious system for expressing large numbers, and devised a method of displacement volumes (also known as the Eureka formula).

Archimedes got the reputation of saying outlandish things. He then staged a performance for the king and his court where he pulled a trireme up onto the beach all by himself using a system of pulleys. A law was then passed that anything Archimedes said was to be considered true. When the Romans were conquering Sicily they put together a special troop who's task was to capture Archimedes alive. Alas he was killed by a soldier from another troop who didn't know who the old man was. Archimedes' last words were 'Don't disturb my circles.'

Where did Aristotle do his work?

Aristotle did much of his work in Athens. He founded a school called the Lyceum. Aristotle liked to walk around the school grounds while teaching his students.

Why did Archimedes invented pulleys?

He made it because it took half the weight of the load off

Describe Aristotle's contributions to government?

For Aristotle, democracy is not the best form of government. As is also true of oligarchy and monarchy, rule in democracy is for and by the people named in the government type. In democracy, rule is by and for the needy. In contrast, rule of law or aristocracy (literally, power [rule] of the best) or even monarchy, where the ruler has the interest of his country at heart, are better types of government. Government, Aristotle says, should be by those people with enough time on their hands to pursue virtue. This is a far cry from the current U.S. drive towards campaign financing laws designed to make the political life available even to those without well-endowed fathers. It is also very different from the modern career politician who derives his wealth at the expense of the citizenry. Aristotle thinks rulers should be propertied and leisured, so, without other worries, they can invest their time in producing virtue. Laborers are too busy

How can you move out on your own when you are fourteen years old?

The minimal age for filing a petition of emancipation is 16. Only a few states have laws that specifically pertain to the emancipation of underaged individuals. The emancipation process is much more complicated and sometimes costlier then many young people believe it to be. Emancipation is rarely granted even in those states where it is prescribed by law. If a minor child perceives themselves to be in an abusive and/or neglectful situation they should tell a school counselor or another adult whom they trust. Other options are contacting the department of family services in the county or city in which they reside. Calling any of the following numbers will connect you with people who can offer assistance depending upon your personal circumstances, National Child Abuse Hotline 1-800-392-3738, Youth Emergency Services Hotline 1-800-899-5437, Youth Crisis Hotline 1-800-448-4663. A web site staffed by teens to assist their peers with all types of problems, or just "talk" is http://www.teenlineonline.org.

Where is Archimedes hometown?

Archimedes was born in the city of Syracuse. This area is in modern day Sicily.

What was Blaise Pascal's religion?

Blaise Pascal was a Catholic; specifically a convert to Jansenism (in 1646 as far as I know). Jansenism was a sect, like the Jesuits are a sect, of Catholicism.

Who are the top 5 greatest mathematicians of all time?

Euler is most probably up there in the mathematics applicable to physics and elsewhere, his name is everywhere (and things have been named after other people which were discovered by him). Gauss is another big name from the physical perspective and from informatics (being mostly applied mathematics) Turing is miles ahead of anyone else.

Here is a list:

Read a bit about these people; Steve Job's impact on the world is nothing compared to these men (they are all men; that was another time).

How do you get Archimedes on Howrse?

On Howrse there was a quiz and the highest contributors got him as a reward.

Contribution in math of Omar khayyam?

he described Pascals triangle 500 years prior to Pascal. He also developed the Iranian calendar, a.k.a. the Jalali calendar which was more accurate than the Gregorian calendar.

Did david hilbert have a sister?

Otto and Maria Hilbert had two children, David being the first born and he also has a sister. Her name is Elise and he was 6 years older than her. This was in Constance Reid's book "Hilbert" published in the 1970's.

Why did Archimedes invent the golden crown?

Archimedes thought that if the gold crown and the gold bar had the same mass and volume, the crown was pure gold and if they didn't, the crown was a fake and the jeweller was a fraud. (I just had to do this for homework. I'm right!)

Who invented roulette?

The word 'roulette' is derived from the words 'small wheel' in French so it's safe to assume that a Frenchman had something to do with the invention of the game. Blaise Pascal is credited with the invention of a primitive roulette game in his quest for a perpetual motion machine in the 17th century. However, the roulette wheel itself is believed to be a combination of a number of Old English, French and Italian games that already existed. The earliest description of the roulette wheel can be found in a French novel 'La Roulette , Ou Le Jour' and this is in 1796. However the earliest reference to the game can be found in 1758 in New France (now Quebec) which actually bans a gambling game called roulette. The European form of roulette (1 green 0 rather than the 0 and 00 in the 'American' version) has been traced back to the German town of Homburg. It is still credited to two Frenchmen though, Francois and Louis Blanc. The single 0 was introduced to increase the odds in the favour of the gambler and hence make it a more attractive option the 00 style of the game. There were even roulette wheels in America that had a 0 and 00 and an American eagle. And when the ball landed in one of these sections the house claimed all bets on the table. When the Germans (one of the largest empires in Europe at the time) outlawed gambling in the 1860's gambling and the roulette wheel moved to the south of France and took hold in Monte Carlo. Monte Carlo quickly became a place where the elite and the rich of the time came to gamble and is still synonymous with the casino today. Meanwhile, at this time, roulette was travelling north through the USA beginning in New Orleans. It was here, because of cheating both by gamblers and operators that roulette became a table top game and it was also here that the roulette wheel as we know it today became standardised.

How can we determine upthrust using Archimede's principle?

The following procedure can be used to determine the upthrust of a body using Archemede's principle. i) Determine the weight of the body using spring balance and record it as W1. ii) Pour water into eureka can up to its spout. iii ) Take empty bearker, weigh it, record its weight as W2 and place it under the spout of the eureka cane. iv ) Record the weight of the body when is totally immersed in water as W3 v ) Remove the beaker and reweigh it togehter with its contents (overflowed water after immersing the stone) record the weight as W4 There fore uor upthrust of the body is given as, upthrust= loss of weight in water = W1-W2 Weight of displaced water= W4-W2 Hence upthrust =loss of weigt in water =weigth of water displaced The following procedure can be used to determine the upthrust of a body using Archemede's principle. i) Determine the weight of the body using spring balance and record it as W1. ii) Pour water into eureka can up to its spout. iii ) Take empty bearker, weigh it, record its weight as W2 and place it under the spout of the eureka cane. iv ) Record the weight of the body when is totally immersed in water as W3 v ) Remove the beaker and reweigh it togehter with its contents (overflowed water after immersing the stone) record the weight as W4 There fore uor upthrust of the body is given as, upthrust= loss of weight in water = W1-W2 Weight of displaced water= W4-W2 Hence upthrust =loss of weigt in water =weigth of water displaced The following procedure can be used to determine the upthrust of a body using Archemede's principle. i) Determine the weight of the body using spring balance and record it as W1. ii) Pour water into eureka can up to its spout. iii ) Take empty bearker, weigh it, record its weight as W2 and place it under the spout of the eureka cane. iv ) Record the weight of the body when is totally immersed in water as W3 v ) Remove the beaker and reweigh it togehter with its contents (overflowed water after immersing the stone) record the weight as W4 There fore uor upthrust of the body is given as, upthrust= loss of weight in water = W1-W2 Weight of displaced water= W4-W2 Hence upthrust =loss of weigt in water =weigth of water displaced The following procedure can be used to determine the upthrust of a body using Archemede's principle. i) Determine the weight of the body using spring balance and record it as W1. ii) Pour water into eureka can up to its spout. iii ) Take empty bearker, weigh it, record its weight as W2 and place it under the spout of the eureka cane. iv ) Record the weight of the body when is totally immersed in water as W3 v ) Remove the beaker and reweigh it togehter with its contents (overflowed water after immersing the stone) record the weight as W4 There fore uor upthrust of the body is given as, upthrust= loss of weight in water = W1-W2 Weight of displaced water= W4-W2 Hence upthrust =loss of weigt in water =weigth of water displaced

Was Archimedes an athiest?

Archimedies, b.287 BCE,d212BCE, was a mathematician most famous for his invention of the screw pump. Not alot was known about his personal life.

What word did the Islamic mathematician Al-Khwarizmi invent?

He didn't invent, but rather used the word, "al-jabr," which means "restoration" in Arabic, to describe his method of defining an unknown quantity as a variable and then manipulating it within an equation to arrive at its value. In other words, "al-jabr" means to perform an algebraic process, hence the word "algebra" being derived from it.

His name (Al-Khwarizmi) is the root for the word "algorithm" although Al-Khwarizmi himself did not coin the word.

What did aristotle consider important to a constitutional government?

For Aristotle, it was necessary to acknowledge that all forms of government were imperfect including democracy. He believed that the best form of constitutional government was one in which the leader had the best interest of the people especially of those people who were in need.

What are Fibonacci's rabbits?

Fibonacci was a famous mathematician who lived around the turn of the 13th century. He is known for a sequence where each number is the sum of the two preceding it. He presented it as the total number of pairs rabbits in a population after a given number of time periods. For mathemetical simplicity, he assumed that each pair of rabbits had to be 1 year old before they could breed, gave birth to a pair and lived for another year before dying.

The sequence goes 1,1,2,3,5,8,13,... and is found in many natural obects (though not rabbit populations!).

What is Aristotle remembered for?

Aristotle is known for his philosophy and for being along with Plato and Socrates the cradle of Western Philosophy. He was the teacher of Alexander the Great and also did some investigation of science. He attempted to classify animals by their basic characteristics.

When did Charles Babbage make his counting machine?

The Difference Machine was started in 1821 but failed its test in 1833. In 1842 Charles Babbage created the Analytical Engine; he completely abandoned the Difference Machine. It was never completed but it helped improve Britain's machine-tool industry. In 1991, the National Museum of Science and Technology built a replica of the Difference Machine; it was a real working one. In 1879, Charles Babbage's son reassembled a section of the Difference Machine, which was auctioned for auction in London auctioned in Sydney for $282,000. On October the 18th 1871, London, UK, Charles Babbage died.
