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...

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 onehalf 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...

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...
