The sun has been producing light for about five billion years but where does all its energy come from? The most common idea is that the sun is burning gas - like a giant fireball in the sky. If this were true, the sun would have gone out long ago. So how is the sun actually fuelling itself? It is converting its own mass into energy. By combining protons (the nucleus of hydrogen) into helium, it squeezes some mass into energy - 4.3 billion kg per second. It is Einstein's famous E=mc^2 which gives us the quantitative relationship between mass and energy, where c is the speed of light.

Space junk is a real problem. NASA now tracks around 20,000 pieces of debris orbiting Earth, most of them larger than 10cm across. Since the average speed of a collision between orbiting objects is 10 km/s these pieces of trash can cause a lot of damage despite their small size.

Scientists in Switzerland have a plan to clean up space junk - it involves creating a 'Janitor Satellite' that will seek out pieces of space junk to drag back into the atmosphere causing them to burn up.

I first saw a Schlieren imaging setup around ten years ago in Melbourne. I was immediately fascinated by the way I could see the warm air coming off my hand. I hadn't expected the currents to be moving that fast or to be so visible. This was a tricky setup to get right because alignment is very important and here I'm just working with what I had lying around the house mostly (plus the mirror). For the best Schlieren photography, making sure the mirror is stable is essential. I want to improve my setup so the mirror doesn't wobble back and forth too much creating the pulsing light and dark sections of this video.

The relationship between index of refraction of air and temperature, pressure, humidity and wavelength is complicated. This website will calculate it for you: http://emtoolbox.nist.gov/Wavelength/Ciddor.asp

I have been obsessed with measurement for a long time and I'm not sure quite how it happened. The world's roundest object played a role in this. I guess I'm just fascinated by how difficult it is to pin down a quantity like a kilogram. A physical object seemed like a good idea until the mass of the international prototype kilogram wasn't as constant as expected. These methods of the Kibble balance and silicon sphere have shown better precision than 20 parts per billion, making them superior to the old method. The agreement between Avogadro approaches

Natural World: Ant Attack
In a quiet patch of forest, life is about to be turned upside down for its animal residents - the ants are coming. Spiders, scorpions and even forest crabs don't stand a chance. As food runs out, the ants, driven on by the ever-hungry grubs in the nest, have no choice but to attack the not so easily defeated termites. Armed with chemical weapons and fearsome jaws that could crush an ant to pulp, they're the ants' toughest adversaries. From the raw terror of battle to the inner-workings of an ant colony, this is television as you've never seen it before.

Natural World: Empire Of The Desert Ants
Against the Chiricahua Mountains of southern Arizona, Empire of the Desert Ants takes an in-your-face look at the violent world of desert honey ants by charting the fate of a single colony over several years as they battle all-comers for survival and dominance over the small patch of desert that is their world. Both the big picture and every minute detail are captured in this dramatic and fascinating film using the latest camera techniques and visual effects. Macro-photography shows the heart of their epic confrontations and the very core of life in the honey ant colony. Battle plans, defensive strategies and 'team' tactics are presented using the latest battlefield technologies. Also revealed are parallel worlds dominated by hidden forces - chemical weaponry, ultra-sonic sound, pheromones, ultra-violet and polarised light - as well as detailed characterisations of the different members of the colony.
