Mathematicians
Often, to completely understand the importance of a mathematical theory, it's essential to know about the person who developed it. This category is where all questions about historically significant mathematicians should be asked.

Charles Babbage in Victorian times. his computer would have been mechanical, rather than electronic.
How did Rene Descartes' discoveries help benefit humankind?
Rene Descartes discoveries helped benefit mankind in many ways. His influence in mathematics is still used today in engineering, science, and every day life. His 'Meditations on First Philosophy' is a standard text at most university philosophy departments today.
Where did Leonardo Pisano Fibonnaci live?
Fibonnaci (c.1170 - c.1250) was also known as Leonardo of Pisa because he was born in and lived most of his life in Pisa, Italy.
- Actor Taylor Brooks was seen in 2007 with an Israeli girl at a celebrity event in Beverly Hills, when interviewed, she mentioned her named was "Elly" but didn't say much else. They whispered in each others ear often and seemed to be very close. The two of them were reportedly holding hands most of the night. Their romantic status is unknown.
How do you solve the epitaph on the tomb of Diophantus?
the tomb of Diophantushere lies a great man. Mathematically his life is heroen inscribed for all to witness:
One-quarter of his life was spent as a boy and a young man. then when 1/7 of his life had passed he entered into matrimony, and 5 years later a son was born to him . Alas! when his son had reached only 1/2 his father's allotted time on this earth, death took him into its arms. to console himself while grieving over his son's death, he explired then discovered this science of numbers during a period of 4 years, after which, Diophantus passed on to a better world.
What was his life span?
Name any veritcle asympotopes of f(x)2x-3?
f(x) = 2x - 3 does not have any vertical asymptotes (nor any veritcle asympotopes).
Who was the father of experimental science and mathematician?
Galileo Galilei was and is sometimes referred to as "the father of experimental science." Galileo didn't take much on faith, rather, he tested his ideas through experiments and expressed them in mathematical form.
How much did Charles Babbage sell his computers for?
nothing, he never built it. although he did take a lot of development money from the English parliament.

What shape has 6 edges 4 faces and 4 vertices?
A triangular pyramid has these characteristics. The regular triangular pyramid is one of the Platonic shapes.
What were 3 goals of Rene descartes?
Descartes 3 goals are: Find a unified set of principles, reconcile the mechanistic view of the world with human freedom, and to find certainty.
What are some famous people who contributed to geometry?
The most famous people that contributed to geometry were Euclid and those great Alexandrian mathematicians who followed his teachings at the university of Alexandria, Egypt: Eratosthenes, Archimedes, Apollonius of Perga, Ptolemy, Diophantus, and Hipparchus. Alexandrian mathematics was a blend of Greek, Babylonian, and Egyptian mathematics, along with theories from countless other mathematicians throughout the Middle East and Asia, particularly from Arabia, India, China, and Rome. Many of the advances in geometry and mathematics were used in what eventually became known as physics. The founders of modern science during the scientific revolution of the 17th century, Nicolaus Copernicus, Johannes Kepler, Galileo Galilei, and Isaac Newton, proved many of their theories by using the Euclidian geometry of Alexandria.
Little is known of Hipparchus's life, but he is known to have been born in Nicaea in Bithynia. Only one work by Hipparchus has survived, and this is certainly not one of his major works. Most of the information which we have about the work of Hipparchus comes from Ptolemy.
Even if he did not invent it, Hipparchus is the first person whose systematic use of trigonometry we have documentary evidence. Hipparchus produced a table of chords, an early example of a trigonometric table. He did this by using the supplementary angle theorem, half angle formulas, and linear interpolation. Hipparchus was not only the founder of trigonometry but also the man who transformed Greek astronomy from a purely theoretical into a practical predictive science. He also introduced the division of a circle into 360 degrees into Greece.
Hipparchus calculated the length of the year to within 6.5 minutes and discovered the precession of the equinoxes. We believe that Hipparchus's star catalogue contained about 850 stars, probably not listed in a systematic coordinate system but using various different ways to designate the position of a star.
The work we have of his, Commentary on Aratus and Eudoxus, was written in 3 books as a commentary on 3 different writings. First, there was a treatise by Eudoxus now lost in which he named and described the constellations. Second, Aratus wrote a poem called which was based on the treatise by Eudoxus and proved to be a work of great popularity. This poem has survived and we have its text. Third, there was commentary on Aratus by Attalus of Rhodes, written shortly before the time of Hipparchus.
The 3 books on which Hipparchus was writing a commentary contained no mathematical astronomy. However towards the end of the second book, continuing through the whole of the third book, Hipparchus gives his own account of the rising and setting of the constellations. Towards the end of the third book, Hipparchus gives a list of bright stars always visible for the purpose of enabling the time at night to be accurately determined. It is thought that this work by Hipparchus was done near the end of his career.
Hipparchus also made a careful study of the motion of the moon. In calculating the distance of the moon, Hipparchus not only made excellent use of both mathematical techniques and observational techniques, but he also gave a range of values within which be calculated that the true distance must lie. He estimated that eclipses have a period of 126007 days. Hipparchus's calculations led him to a value for the distance to the moon of between 59 and 67 earth radii, quite remarkable in that the correct distance is 60 earth radii.
Hipparchus not only gave observational data for the moon which enabled him to compute accurately the various periods, but he developed a theoretical model of the motion of the moon based on epicycles. He showed that his model did not agree totally with observations, but it seems to be Ptolemy who was the first to correct the model to take these discrepancies into account. Hipparchus was also able to give an epicycle model for the motion of the sun, but he did not attempt to give an epicycle model for the motion of the planets.
I believe Archimedes (a Greek mathematician) discovered buoyancy in 212-250 B.C.. He was hired by the king of Syracuse on the island of Sicily, to find out if his crown was made of true gold or just another metal with a similar physical state. He took a bath one day and realized that his mass displaced the water in the bath tub when he sat down. He then measured a bar of true gold with the same mass as the crown comparability in water. The goldsmith had made the crown with both gold and metal. For a full explanation of how the buoyancy principle works go to the related question "What is the buoyancy principle?" in the Related Questions section below.
Did Pythagoras refuse to eat bread unless it was cut in a certain way?
he did not eat beans because he thought they weren't pure enough.
Did Leonhard Euler invent mathematics?
L. Euler stands alone as one of the greatest mathematicians ever, as well as one of the greatest mathematical teachers ever. However, no single person, not even Euler, can be said to have "invented" mathematics, because it predates written history. Euler did contribute quite a bit though; especially in regards to the standardization of notation, the use of infinite series, functional analysis, and infinitesimal calculus.
