On Tuesday I posted about ways to save energy at home with practical tips. Today I thought I’d look at our home and make some public commitments of things I can realistically change. The house is fairly well designed – it was a pre-airconditioning house for the desert so is up on stilts with all bedrooms […]

I have an addictive new app from Science Alert, which brings the latest science research in Australasia right to my phone. I’m sure you can guess why I like it. The other day it had this study from Wendy Miller at Queensland University of Technology showing that green homes use 80% less energy. Living in the […]

Quick quiz – do you think Australia’s jungles are more like the jungles of Indonesia (directly north) or the jungles of India (several islands away)? Seeing as there’s no point in asking a question with an obvious answer, you probably got it right by saying India, even if you have no idea why or how. The […]

Sorry about the delay, we were without power for a couple of days last week, apparently a bird took out a whole transformer. The girls enjoyed the extra excuse to have takeaway 🙂 While I catch up and rearrange, here are last week’s answers in place of this week’s quiz. 1.    The Kessel Run is […]

We fascinate ourselves, we want to know all about us. But we have a blind spot, an assumption that we must be the best. There’s something to back this up – after all, we dominate an entire planet and have reached beyond. Surely this means we are the pinnacle of creation? The topmost twig of […]

It’s been said that the reason dinosaurs are fascinating is because they’re ‘big, fierce and extinct.’ Olympus Mons, or Mount Olympus, on Mars almost fulfills those criteria – it’s the solar system’s biggest volcano, it’s a volcano, and seeing it’s on another planet it’s as inaccessible as dinosaurs. Firstly the stats – Olympus Mons is […]

While researching this post (watching cartoons on YouTube) I discovered that Road Runner cartoons are from the 60s – a lot older than I thought. Which shows that some things are timeless, especially what makes us laugh. Road Runner is funny because it breaks the rules. When people watch something like Road Runner they always […]

And if we’ve already found over 700 with just a few years of looking then how many billions really exist? It’s a crowded universe. Exoplanets are planets that orbit other stars. Most we have found so […]

Pendulum Waves

February 6, 2012 Energy and Change

First watch this video: How cool is that? And did you like the setup in the beginning when they showed you there were no tricks, it’s just a line of pendulums of different lengths. This, my friends, is all about maths. And physics, but at this level physics is pretty much applied maths. Pendulums Pendulums […]

How did you do? I had good fun working out the answers. 1.     Lungs in birds are very different to ours, they are more efficient. In mammals we breathe into large dead end sacks of alveoli, use some oxygen then have to get rid of the low oxygen air taking up the space. […]
