Doing Maths can be a real pain, but…

July27

“Mathematics can be difficult, and a new study shows even thinking about doing it can physically hurt. Researchers Ian Lyons and Sian Beilock at the University of Chicago have shown how increases in brain activity appear in regions associated with pain and threat detection, when people with “high levels of mathematics-anxiety” are presented with mathematic […]

Finding Gradients – Pt II

July25

Google Earth provides a practical tool to find gradients between two points . In this example, we are interested in the gradient between Mt Fuji and Yamanakako. The gradient is equal to the rise in elevation divided by the run (horizontal distance). In this portion of the cross-section we can calculate the gradient to = a […]

Finding Gradients – Pt 1

July20

If a road is steep we say that it has a “steep gradient”. Gradients are defined as the amount of increase in altitude (or rise) divided by the distance (or run) travelled. In the following diagram, you can find the gradient of the red line by taking any two points – here we are using […]

Cracking the Sailing Equation…

July16

“The cat was let out of the bag – so to speak – very early on in Team NZ’s testing programme in the new AC72 class, after a sailing enthusiast and amateur photographer snapped pictures of the team out training, which appeared to show both hulls of the Kiwi boat flying clear of the water. […]

Palindromes

July13

A palindrome walks into a math class and says “Syas dnas salch tama Otni Sklawem Ordnilapa” 1111122222233333334444444455555544444444333333322222211111 In mathematics, a palindrome is a number that reads the same forward and backward. For example, 282 and 707. I’m guessing that’s why I enjoyed driving my Mazda 808, 323 and 626 a few years ago? By definition, all numbers that […]
