Lift is an important concept, not only in flying but also in sailing. This week I’m talking to Olympic Sailor, Hunter Lowden.

What happens when you decrease the pressure around a liquid? It boils. Water boils at room temperature once the pressure is low enough. What is interesting is that this decreases the temperature of the liquid. The fastest molecules escape, leaving the slower ones behind. Using this trick with liquid nitrogen, it is possible to create

How long is the coastline of Australia? One estimate is that it’s about 12,500 km long. However the CIA world factbook puts the figure at more than double this, at over 25,700 km. How can there exist such different estimates for the same length of coastline? Well this is called the coastline paradox. Your estimate

When pressure is applied to ice, its melting point is reduced so it turns to water. When the pressure is removed, however, it turns back into ice. This process is called ‘regelation.’ Big thanks to Art of Ice Sculptures www.icesculpture.com.au who donated the beautiful block of ice.

There seems to be confusion about what radiation is and where it comes from. Many people believe it is the radiation that comes directly from nuclear power plants that poses a threat to public safety. In fact it is the radioactive atoms, which can escape in the event of an explosion, that pose a safety

An atom is mostly empty space, but empty space is mostly not empty. The reason it looks empty is because electrons and photons don’t interact with the stuff that is there, quark and gluon field fluctuations. It actually takes energy to clear out space and make a true ’empty’ vacuum. This seems incredibly counter-intuitive but

Raw interviews: http://www.youtube.com/watch?v=8dcw98B2Nzg The question has arisen often enough that I thought I’d answer it. If you hold views that are consistent with the majority of the population, does that make you stupid? I don’t think so. Science has uncovered a lot of counterintuitive things about the universe, so it’s unsurprising that non-scientists hold beliefs
