Art and science

by , 23 May 2014 | 2 comments

The eyes have it. Bright, colourful butterflies and birds easily catch our attention. But to visualise bacteria, we need to get creative. A picture tells a thousand words. But how many words go into a picture? For molecular biologist and artist David Goodsell, pages upon pages of research go into each artistic creation. David makes…

Confessions of a craft tragic

by David, 20 August 2013 | 0 comments

Written by Maithili Mehta As well as loving maths, I also adore craft. Knitting, crochet, paper craft, you name it, I love it. Up until recently, I thought the extent of interaction between my two beloved areas was in resizing a knitting pattern (soooo many fractions) or knitting a moebius scarf/klein bottle. Imagine my excitement…

Make a magnetic rocket

by Carol Saab, 15 August 2013 | 2 comments

What happens when your rocket fuel is magnetic force? Our latest video shows you how to make a rocket using super strong rare-earth magnets, skewers, ball bearings and blu-tack. Check it out in slow-mo and watch for something rather curious… when the magnets move down the track, momentum is added until the final ball flies off at a…

Extract DNA from a banana!

by Carol Saab, 8 August 2013 | 3 comments

DNA is the blueprint and genetic guide for every living thing, and units of DNA are tiny. So how can we see it with our own eyes? Many DNA units form a long, stringy molecule that is easily visible and easy to extract from particular living things, like peas or a banana. Our latest video shows you…

Electricity, magnets, momentum and cool slow-mo footage. It’s all in our new video! Take a look: Video transcript available here. Both the ring launcher and the rail gun use called Lenz’s Law to give an object momentum. Lenz’s Law can be observed when a magnet moves over a piece of wire.  A current is induced in…

There’s no such thing as suction

by Carol Saab, 25 July 2013 | 0 comments

This may surprise you, but there’s no such thing as suction. In this week’s video we look at what creates ‘suction’; air flow and areas of high and low pressure. Video transcript available here. Imagining the ‘power’ of the air around us is difficult, but the ways you can demonstrate it are quite cool. When…

To make ice-cream we use a whole bunch of different principles from physics and chemistry. In our new video, we use salt to reduce the freezing point of water to make delicious, homemade ice-cream in minutes. Check it out: Video transcript available here. Adding salt to the ice allows the water to get to a…

How people sense acceleration

by Carol Saab, 11 July 2013 | 1 comments

Where’s your head at? Our ability to sense the rotational movement of our head comes from a set of organs in the inner ear. One of these organs, the utricle, also gives us the ability to sense acceleration. Our latest video takes a look inside our ears, and how you can make a device to…
