The objects commonly referred to as platonic solids are regular solids or better still, they are called regular polyhedra. The solids are convex polyhedra that have equivalent faces made up of regular polygons that are congruent-the word polyhedra means ‘’many faces’’ in Greek. There are exactly five of the platonic solids called polyhedra and they are:

July 25th, 2011The German philosopher Carl G Hempel, in his beautiful and elegant treatise written in 1965, demonstrated that there were flaws in the long held scientific processes of inductive reasoning, generalization, and falsifiability of logic as it is commonly understood and practised.
The background of inductive reasoning: Hempel used raven as a central point of his argument against the long held pattern of scientific reasoning and he used the following example: Imagine that you had taken a long walk as a scientist and you happened to see a raven that you noted to be black, you might make your comment and say, ‘’I saw a black raven.’’ If sometimes after that you noticed a few more ravens that were black, you might say ‘’what a perfect coincidence, these other ravens are black too.’’ If time passed by and in your adventure you happened to see more ravens that were black, the chances are that you could say ‘’this is much more that coincidence’’ and with the instincts and natural practice of an observant scientist, you therefore form a hypothesis ‘’All ravens are black.’’

Arithmetic and its Fundamental Theorem
July 14th, 2011The natural number system-the set of numbers that comes to us naturally- is comprised of mainly composite and prime numbers. Numbers obtained by multiplying two other numbers are composite numbers while prime numbers are numbers whose factors are themselves and 1 only. Examples of composite numbers include numbers such as 6 which is obtained by multiplying 2 and 3. Prime numbers 2 and 3 are said to be the factors of 6 or they are divisors of 6. Prime numbers are so many and they are typically known as numbers with two factors only-itself and 1.

The Algebraic Concept of x- and y-intercepts
July 13th, 2011Graphical representation of the x-and y-intercepts is quite simple. The intercepts at the x-axis, called x-intercepts are points where the graph crosses the x-axis while the intercepts at the y-axis, called the y-intercepts are points where the graph crosses the y-axis. However, the main challenge of the intercepts comes when we attempt to provide algebraic expressions and equations to the x-and y- intercepts.
