Around 300 BC, the Greek Euclid wrote "The Elements", which stated five postulates upon which he based his theorems. These postulates form the basis of what is known as Euclidean geometry, and is the foundation of the geometry most of us have studied. Euclid’s...
 By: Mansoor Alam Variance is a term which indicates the variation of a given set of statistical data from the measured value. Mathematically, the square root of standard deviation is called variance, denoted by σ2. In statistics, there are two type of data distribution. 1.Raw data...
What is non-Euclidean geometry?
By: Steven Mars
Non-Euclidean geometry is a branch of geometry that does not follow Euclid’s fifth postulate, called the parallel postulate. The Egyptian Euclid lived around 300 B.C. His parallel postulate was part of his most famous work, "Elements". He used other mathematicians of his time...
What is non-Euclidean geometry?
By: Jordin Lumsden
In 1482, Euclid's Elements was published, presenting the first clear and logical framework for a geometrical system. This Euclidean Geometry, which was known simply as 'geometry', is an axiomatic system, in which all theorems are derived from a smaller number of axioms. Euclid gives five...

Have you ever wanted to picture yourself in a perfect world where no one is ever misunderstood? Have you ever imagined a meeting where no one misunderstands anyone and no one ever has to re word a statement to help someone understand the meaning of...

Did you know that the words you speak out loud make up less than half of what you say? Even when you don't say a single word, your body is talking to other people all the time. Your gestures, facial expression, eye movements, and even...
Zero Division
By: Davian Chin
On the subject of "Zero Division", I would definitely agree that zero division is possible in a very general case. First, I would just like to give a short background to describe the motivation of my arguments. One can view the subject of Mathematics as...

A pioneer in math and physics, Leonhard Euler (1707-1783) left a legacy unmatched by few others in his field. The leading mathematician of his day, Euler’s contributions range from mathematical notation to the orbit of comets. (Fittingly, in 2002, an asteroid was named in...
Zero Divided by zero
By: Martyn Winstanley
I fear that people may have been over-complicating this problem. The argument seems to be twofold, the first part being is division by zero possible in computers which rely on real numbers to make their calculations? The short answer to this is no (at least...
