Mathematicians

It was the mathematician William Jones who first used pi as a mathematical symbol in 1706

The most widely known anecdote about Archimedes tells of how he invented a method for determining the volume of an object with an irregular shape. According to Vitruvius, a votive crown for a temple had been made for King Hiero II, who had supplied the pure gold to be used, and Archimedes was asked to determine whether some silver had been substituted by the dishonest goldsmith.

Archimedes had to solve the problem without damaging the crown, so he could not melt it down into a regularly shaped body in order to calculate its density. While taking a bath, he noticed that the level of the water in the tub rose as he got in, and realized that this effect could be used to determine the volume of the crown.

For practical purposes water is incompressible, so the submerged crown would displace an amount of water equal to its own volume. By dividing the mass of the crown by the volume of water displaced, the density of the crown could be obtained. This density would be lower than that of gold if cheaper and less dense metals had been added.

Archimedes then took to the streets naked, so excited by his discovery that he had forgotten to dress, crying "Eureka!" (Greek: "εὕρηκα!," meaning "I have found it!"). The test was conducted successfully, proving that silver had indeed been mixed in.

The year in which this story took place is unknown, but was no earlier than 270 BC, when Hiero II was crowned king.

yes he was a brilliant inventer

Modern biology and modern logic are grown from the work begun by Aristotle.
These sciences have developed by building upon his work. Biology especially has benefited from his work.
Aristotle's system remained the basic framework for the field of logic until the late 19th century
If A is true of all B
if B is true of all C

Then A is true of all C

Any number where all the digits add up to 3, 6, or 9 is divisible by 3. Example: 12 = 1 + 2 = 3 so 12 is divisible by 3. 259 (2 + 5 + 9 = 16 = 1 + 6 = 7 so 259 is not divisible by 3). and last 267 (2 + 6 + 7 = 15 and 1 + 5 = 6 so 267 is divisible by 3).

About 1.4 grams. But it all depends on the paperclip style, size, and manufacturer.

how fast would u be at math if he hadnt have come up with the idea of a calculator???? he was an amazingly smart man, for more information, go to: http://library.thinkquest.org/C0115420/Cyber-club%20800x600/BIO/Charles%20Babbage.htm and http://www.computerhistory.org/babbage/charlesbabbage/ alot of information on hjim, he invented muhc muhc muhc muhc more than the calculator, and if he didn't invent it, he sure had alot to do with the ideas.

1. in italy

the car has more density than water i.ethe weight of the water displaced is more than the bouyant force acting on the car.

According to Aristotle the Universe is a sphere and Earth is at the centre.

3x2 =6

3x0.7 =2.1

Add them

=8.1

74 plus 20% of sales = 89.

It is: 6/111 of 748 = 40.'432' recurring '432'

No.

The famous person Aristotle had as a teacher was Plato.

Sadly, none of her Hypatia's works survived. So, it cannot be said what math would be like without her contributions.

(8 x 7) + (6 x 5) + 4 + 3 - 2 - 1

= 56 + 30 + 7 - 3

= 86 + 4

= 90

The decimal conversion of the equivalent fractions of 3/4 should be equal to 0.75.

Keep the secrets of the school and not eat beans. No, really: Pythagoras had a neurotic fear of beans.
