The Beginning of Math
Math initally came from the need to measure time and to count. These two activities along with locating, designing, playing, and explaining are theorized by (A. J. Bishop 88) to be responsible for a culture's development of math. Archaeologists have discovered notched bones and patterns on walls of Ice Age caves.

The Father of Mathermatics
Archimedes is generally considered to be the greatest mathematician of antiquity and one of the greatest of all time.[2][3] He used the method of exhaustion to calculate the area under the arc of a parabola with the summation of an infinite series, and gave a remarkably accurate approximation of Pi.[4] He also defined the spiral bearing his name, formulas for the volumes of surfaces of revolution and an ingenious system for expressing very large numbers. (Ashley)

Archimedes' argument for Pi
The first theoretical calculation seems to have been carried out by Archimedes of Syracuse (287212 BC). He obtained the approximation
223/71 < < 22/7.
Before giving an indication of his proof, notice that very considerable sophistication involved in the use of inequalities here. Archimedes knew, what so many people to this day do not, that does not equal 22/7, and made no claim to have discovered the exact value. (Emma Greve)

The Salamis Tablet
The oldest surviving counting board is the Salamis tablet (originally thought to be a gaming board), used by the Babylonians circa 300 B.C., discovered in 1846 on the island of Salamis.
It is a slab of white marble measuring 149cm in length, 75cm in width and 4.5cm thick, on which are 5 groups of markings.

Pythagoras was an influential Greek mathematician and philosopher, best known for the theory to which he gave his name.
Very little is known about Pythagoras's life. He is thought to have been born on the Greek island of Samos, and travelled widely in his youth, visiting Egypt and Persia. He settled in the city of Crotone in southern Italy. There he began teaching and soon had a clutch of students who lived a structured life of study and exercise, inspired by a philosophy based around mathematics. This circle came to be known as the Pythagoreans. (Courtney Day)

His conclusion was that the number of successes was related to the area under a cycloid whose generating circle had a diameter equal to the length of the stick. http://mathworld.wolfram.com/BuffonsNeedleProblem.html (Chrystie Steffens) 
Neptune
The first planet to be discovered was Uranus by William and Caroline Herschel on 13 March 1781. It was discovered by the fact that it showed a disk when viewed through even a fairly low powered telescope. The only other planets which have been discovered are Neptune and Pluto. These were predicted using ingenious mathematical arguments based on Newton's laws of gravitation and then observed near their predicted locations.

Creation of Leap Frog
When Mike Wood discovered that the toy market offered nothing to help his threeyearold learn math, he decided to do something about it. In 1995, he and Bob Lally founded LeapFrog and introduced the company's first product, the Phonics Desk. Four years and many successful new products later, Bob launched the LeapFrog SchoolHouse division in 1999, in response to countless requests from educators to customize LeapFrog's awardwinning technology and educational products for the classroom.

Creation of the Abacus 27002300 BCE
The period 2700%u20132300 BC saw the first appearance of the Sumerian abacus, a table of successive columns which delimited the successive orders of magnitude of their sexagesimal number system. Babylonians may have used the abacus for the operations of addition and subtraction. (Steve Platt) 
Zip Code
Robert A. Moon, a career postal employee who in 1963 won a 20year fight for what was to become the ZIP code. The Zoning Improvement Plan, as ZIP was more prosaically known, represented an ascendancy of numbers over letters, arriving about the same time the telephone company was switching to sevendigit numbers from letter exchanges like BUtterfield 8.

Perelman solved Poincar conjecture
Poincar Conjecture is one of the seven Millennium
Prize Problems, for which the Clay Mathematics Institute offered a $1,000,000 prize for the first correct solution. After nearly a century of effort by mathematicians, Grigori Perelman, a Russian mathemacian, sketched a proof of the conjecture in a series of papers made available in 2002 and 2003. The Poincar conjecture remains the only solved Millennium problem.

Polyak  Using Abstract Mathematics to Solve RealWorld Problems
Nearly 25 years ago, Polyak developed a theory called nonlinear rescaling (NR) for solving constrained optimization problems. The methods are essential for solving complicated, realworld technological problems with thousands of variables and tens of thousands of constraints. His theory was used in technological advances to help destroy cancerous tumors.
