John Von Neumann

     In 1903, Budapest had a new member of the population. John von Neumann was an inventor and mathematician who was born into a hungarian family. Max and Margaret von Neumann were his parents. John Von Neumann was the oldest of 3 children in the Von Neumann family.

     John Von Neumann was known for his amazing creativity and mathematics. He went into a career as a professional mathematician. Part of his job was to create papers that reviewed his own theories about mathematics. After he wrote and released them, Von Neumann would show other mathematicians his work.

     In his later life he got awarded the Bócher Memorial Prize and the Enrico Fermi Award. He was diagnosed with bone cancer and 18 months later he, sadly, passed away. Although he isn’t alive today, his legacy lives on.

Einstein

    Albert Einstein was born on March 14,1879, in Ulm, Germany. In his early years in education, he was a poor student, and many teachers thought he was retarded. He had many speech problems when he was nine years old. But many teachers didn't know that Albert was fascinated by the wondrous and confusing world around him. However, like many kids, he disliked school and ended his secondary education at age sixteen. He had gotten himself expelled by his bad attitude, and found a way to quit school without hurting his chances for university. He mastered many things, including calculus, the measurement of irregular shapes, and the form of math used to solve problems involving physics and engineering. However, Einstein quickly became infamous by his mathematical expression e=mc 2 because it was used to set off a bomb that destroyed Hiroshima, Japan. Albert Einstein died in Princeton,1955.

Pythagoras

                                       

                 Pythagoras, (A.K.A Pythagoras of Samos) , was a renowned Greek mathematician, mostly known for his invention of the Pythagorean Theorem, which consists of a square + b square = c square, indicating that two expressions equal a answer, also called a expression. The Pythagorean Theorem is well known through all of school, through all the grades, from the simple 2+2=4, to complicated geometry problems that even I can't solve . Pythagoras was an important mathematician, and contributed many important things to the world of math.

Cheryl Elisabeth Praeger

Cheyl Elisabeth Praeger was born on September 7, 1948 in Toowoomba, Queensland, Australia. She hasn't died yet which would make her 67.
Praeger's parents were named Eric and Queenie. They both had to leave school to earn their living. They didn't have a chance on participating in a higher education.
After leaving her school she enrolled in the Universety of Queensland, and got her B.Sc degree in 1969.                                                                                  2
Praeger studied the functional equation x (n+1)- x (n)= x   (n) + x(x(n) and x is an integer valued function of the integer variable, n, and found three parameter family of solutions.

Archimedes

Archimedes

  Archimedes is universally known to be the greatest of ancient mathematicians. He studied at Euclid's school, but his work far surpassed than the works of Euclid. For example, some of Euclid's more difficult theorems are easy analytic consequences of Archimedes' Lemma of Centroids. His achievements are particularly impressive given the lack of good mathematical notation in his day. His proofs are noted not only for brilliance but for unequaled clarity, with a modern biographer describing Archimedes' treatises as "without exception monuments of mathematical exposition . so impressive in their perfection as to create a feeling akin to awe in the mind of the reader." Archimedes made advances in number theory, algebra, and analysis, but is most renowned for his many theorems of plane and solid geometry. He was first to prove Heron's formula for the area of a triangle. His excellent approximation to √3 indicates that he'd partially anticipated the method of continued fractions. One of his most remarkable and famous geometric results was determining the area of a parabolic section, for which he offered two independent proofs, one using his Principle of the Lever, the other using a geometric series. Some of Archimedes' work survives only because Thabit ibn Qurra translated the otherwise-lost Book of Lemmas; it contains the angle-trisection method and several ingenious theorems about inscribed circles. Thabit shows how to construct a regular heptagon; it may not be clear whether this came from Archimedes, or was fashioned by Thabit by studying Archimedes' angle-trisection method. Other discoveries known only second-hand include theArchimedean semiregular solids reported by Pappus, and the Broken-Chord Theorem reported by Alberuni.
