How decimals indicate fractions
By: Nick Ford
Decimals and fractions are very closely related. Both can be used to express and manipulate parts of whole numbers. To appreciate decimals we need to thoroughly understand fractions. A fraction is a device to express how many parts we have of the whole. To do...
What is an artificial neural network?
By: Francis Harris
The artificial neural network is a computational model inspired by the real neural networks found in the human brain. It is an approach found within the field of Artificial Intelligence (AI) - that area of study arising in the 1950s which tries to get computers...
Understanding Triangles
By: Steven Mars
A triangle is a polygon formed by three connecting straight lines. The sum of the angles of a triangle in plane geometry is equal to 180 degrees. Examples are 90+30+60, 30+30+120, and 45+45+90. The area of a triangle is one-half the base times the height...

Statistical data helps social scientists understand and describe social phenomena, but should never be interpreted as infallible or irrefutable proof.' While good researchers take precautions to ensure the reliability and validity of their findings, no one is capable of designing a perfect' study that...

Poka - yoke is a Japanese term for mistake proofing. It is a device used in manufacturing as part the Zero Quality Control method, helping to ensure that build processes are right first time. Shigeo Shingo, an industrial engineer at Toyota, was the pioneer of...
Probability explained
By: Peter Flom
The probability of an event is a number between 0 and 1 that expresses how likely the event is to occur. An event which cannot happen has a probability of 0, and one which is certain has a probability of 1. We often use probability...

If one were to apply the laws of probability when considering the life of Sophie Germain, the odds of a French baby girl born in 1776 becoming one of history's most influential mathematicians would be, in a word, astronomical. Born into the Parisian merchant class...

Triangles are a simple shape, but they can teach us a lot about geometry.It's easy enough to draw a triangle - for example, by making three dots on a piece of paper and then drawing straight lines connecting them. But because it's drawn on...
