Whenever an object spins through the air it experiences a ‘Magnus Force’ due to friction between the air and the object’s surface. This force was originally identified while studying the trajectories of cannon balls (though earlier observations of this effect exist). The Magnus force is essential in most ball sports including golf, cricket, tennis, and

Are all people on Earth really connected through just six steps? There’s much more science in this than I initially expected.

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
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
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.
