Please, no more rubbish about times tables!

The human adult spine has 33 vertebrae, the bones that support the rest of the body.  The lumbar vertebrae, in the lower back, bear the weight of the upper body and are very flexible.  If you have lower back problems, it’s often your lumbar vertebrae that are struggling under the weight they have to bear.

Multiplication is a lumbar vertebra in the spinal column of mathematics.  Multiplication supports the weight of, amongst other things: Continue reading “Please, no more rubbish about times tables!”

The Wisdom of the Crowd

Sir Francis Galton was a statistician in the 19th century. Thanks to him we have concepts such as correlation and standard deviation.  Galton, it would seem, thought through the filter of statistics, a genius who produced hundreds of papers and books on fields as diverse as meteorology, historiometry and psychometrics and who pioneered the use of questionnaires to gather better information for his statistical analyses.

Last week, at my school’s Open Evening, we conducted a mathematical experiment based on one of Galton’s observations.   Continue reading “The Wisdom of the Crowd”

Mathematical Stories

Everyone loves a good story. Stories transport us to another time or place and make us think outside of ourselves, question our status quo. The mathematics classroom is not one of the more predictable places to find a good story, but that doesn’t mean there aren’t any.  One of my favourites goes something like this:

The Pythagoreans were an ancient mystical sect, a group of men who wore white robes and spent their days measuring and wondering; wondering at the beauty of nature and the expanse of the cosmos, resolute in their belief that the universe could be explained and deciphered using mathematics. They were masters of geometry and sought to understand the workings of the world by analysing numbers and shapes and the intersection of the two. One of the Pythagoreans’ core beliefs was that any number could be written as the ratio of two others in the way that 6 is 12/2, or 2.333333… is 7/3. This was the gift of the gods, that any number could be expressed through any other. It felt complete, it felt perfect. But for the Pythagoreans, perfection was about to be shattered.
