Mac Mouse Magic for Mathematical Memories

May30

A few of us met the Macintosh when it was launched in 1984, and I can still remember a sample being on trial at my first school. Sitting apologetically in the corner of the main staffroom, it was a rather odd looking, all-in-one computer with a strange device attached called a “mouse”. Perhaps that is […]

In a recent New Zealand study, the amount that graduates in different fields of study can expect to earn has been revealed – and the Government says it should make school students stick with science and mathematics. Yes, you read it here…Mathematics makes a BIG difference in potential future earnings! That should be great motivation […]

Lies, Damned Lies and Statistics

May26

Mark Twain made popular the quote, “Lies, damned lies, and statistics” to describe the ability of some people to use the power of numbers to persuade others to believe their viewpoint, particularly to give statistical support for weak arguments. Take this graphic for example: “It is hard to imagine how to construct a less informative […]

Measurement works if you have the same units!

May23

The Mars Orbiter was lost in 1999 because the Nasa team used imperial units while a contractor used metric. The $125m probe came too close to Mars during its orbit and was probably destroyed by the planet’s atmosphere. An investigation said the “root cause” of the loss was the “failed translation of English units into […]

Geometry rules in Nazareth

May18

H3 noticed this striking geometric pattern in the Basilica of the Annunciation in Nazareth. This is a modern Catholic church, built over the remains of older Byzantine and Crusader churches. Supposedly the home of Mary, this popular tourist attraction has many mathematical elements in both its (largely concrete) construction and interior and exterior design.

Constructing a Parallelogram

May13

This excellent visual guide shows you how to construct a Parallelogram – a shape with two opposite pairs of parallel sides. I remember a friend of my father who, when giving marching orders to his army group, said, “Keep those arms paralysed to the ground!” Of course, he meant “…parallel to the ground” but I […]

German Soccer shootouts are mathematically better

May9

In an interesting article by DW on soccer and math, an analysis was done of penalty shootouts in the European Soccer league. Research showed that most shooters have a 75 percent chance of scoring. But according to binomial probability, and common preconceptions, the Germans do much better. For a world class soccer player, scoring a […]
