Some months a go I filmed a slinky falling in slow motion. Now I have interviewed the public about what they expect to happen for ABC TV's Catalyst program and this is the result. Slinky Drop 2
NOTE: This video will appear in a playlist on Smarter Every Day hence the references to Veritasium. Destin does lots of cool science stuff - check out his channel if you haven't already www.youtube.com We have been collaborating on rotational motion, which is timely for some of the videos I've been doing lately. In this video I talk about gyroscopic precession - the Gyroscopic...
Objects hang heavy side down, but what happens when you spin an asymmetrically weighted disk - well the heavy part actually rises to the top. Why is this? Spinning Disk Trick
www.abc.net.au 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 located (only about 400km from Earth's surface). So astronauts still experience a gravitational pull - it's just that they and the space station are in free fall so they are accelerating together towards the Earth. The space station doesn't crash into the Earth because of its orbital velocity - it's going 28000 km/h so as it falls, the Earth curves away from it. Why Are...
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. Where Does The...
The aurora borealis or northern lights is one of the most spectacular natural displays on the planet. Theories about its origins have been debated for centuries and common misconceptions persist that the aurora is the sun's rays scattered off ice crystals in the high atmosphere. In truth, the light is created more than 100km above Earth's surface as high speed electrons and protons ejected from the sun in a solar flare or coronal mass ejection collide with air molecules in the upper atmosphere. The charged particles from the sun excite air molecules which then de-excite by emitting light. The display is most common around the north and south poles because the Earth's magnetic field deflects the solar wind from the equator to the poles. Here the magnetic field dips towards the Earth's surface, channeling the charged particles into the atmosphere. Music is by Kevin MacLeod incompetech.com, the song is called Mirage Northern Lights...

Basic Saucer Physics (a video response)

This is not part of the actual course about humans. It's rather a video response to http://www.youtube.com/watch?v=h0SZZTBQmEs, an earthling video about the behaviour of a spinning disk. If you are an alien travelling around in a spinning disk, this might interest you. Earthlings 101 on...

Answer to the spinning tube question

This is made with Google SketchUp 3D drawing CAD program (check it out, it is really simple and royally free). The add on that animates/interacts these 3D objects is "Sketchy Physics" (also free). It allows to make a simple physical interaction simulations and the use of motors, servos hinges...
