Veritasium

http://www.abc.net.au/catalyst/team/default.htm I have been working with Catalyst on ABC1 to bring some Veritasium to Australian TV. In this segment I ask why astronauts in the space station are weightless. The most common answer is because there is no gravity in space. But of course there is gravity in space, especially where the space station is

Now we look at the

I am working on some big new projects I’m excited to share with you! Join the Veritasium email list so you don’t miss out: http://eepurl.com/bv2eZb So this video is a little different from most of the others. The channel is an element of truth, after all, not an element of science. This is my truth.

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

UV at ground level is non-ionizing but it damages DNA and causes photoaging – how? Also, it turns out glass doesn’t block all UV (specifically UVA passes through). This is something I learned filming with the UV camera inside. Special thanks to Dr. Hayley Golbach, @hayleysgold on twitter Tweets by hayleysgold Ultraviolet light causes damage

The merging of two neutron stars was detected by gravitational waves and then by telescopes in all parts of the electromagnetic spectrum. This is a historic detection as it demonstrates: – the first gravitational waves detected from inspiraling neutron stars – the first joint observation by gravitational wave and electromagnetic wave astronomy – identification of

When sunlight shines through a small hole, it casts a circular image on the wall regardless of the shape of the hole. The size of the hole also doesn’t affect the size of the image. This counterintuitive demonstration shows that the hole is acting like a pinhole camera, producing an image of the sun on

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

Lift is an important concept, not only in flying but also in sailing. This week I’m talking to Olympic Sailor, Hunter Lowden. But before I get to the physics of sailing I thought I would explain lift since it’s generally poorly understood. minutephysics http://bit.ly/Muh6CC 1veritasium http://bit.ly/MrupzL efit30 http://bit.ly/O4CMme appchat http://bit.ly/NxAMlX erikaanear http://bit.ly/MdyUzQ whoisjimmy http://bit.ly/LtFzpW numberphile

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.

A lot of people would say different incentives motivate different people, or in different circumstances, but in psychology there is a sizable body of evidence that in order to learn skills, positive feedback is more effective.

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
