Rubik Cube – a colourful creation!
The first person to solve a Rubik’s Cube spent a month strugglingto unscramble it. Erno Rubik was born on July 13, 1944, about a month after D-Day, in the basement of a Budapest hospital that had become an air-raid shelter. His father was an engineer who designed aerial gliders. As a boy, Rubik loved to […]
Never look directly at the sun, except now
As a young child I can remember being told to never look directly at the sun, unless I had especially dark glasses on, such as those used for welding. This image is, therefore, more stunning when you realise that it is showing fine details across the heaving cauldron that is the sun’s surface. The darker […]

Take a humble door knob and shine a strong flashlight to reveal a geometric shape. What is it?
I’m feeling blue, 11 dimensions at a time!
Neuroscientists have used a classic branch of maths in a totally new way to peer into the structure of our brains. What they’ve discovered is that the brain is full of multi-dimensional geometrical structures operating in as many as 11 dimensions. We’re used to thinking of the world from a 3-D perspective, so this may […]
How the Ambiguous Cylinder Works
Mathematical Ilusion
Now that looks really weird!
Lakes in the desert, the moon larger when it is on the horizon, Escher’s famous sketches – and, then this recent pic which somehow doesn’t quite seem right? The scale is not correct…or, is it? (For an explanation, check out the Post Support.) Optical illusions are a fun way to get connected with Spacial Geometry. […]
Coordinates the modern way!
So, you are sitting in a math class, wondering why you are doing Coordinate Geometry? You know the feeling – using (x,y) to show the place of a point on a Cartesian Plane. The Cartesian Plane was named after the French mathematician, Rene Descartes (right). He was a really bright Math guy as well as […]
Could Pythagoras do your Mathematics?
Before we answer that question, let’s see who Pythagoras was! Actually, there is so much fact and fiction surrounding Pythagoras that it is sometimes difficult to locate the real hypotenuse, but at least we can try! Most Greeks at this time (6th Century BC) believed that gods and spirits moved in the trees and the […]
