This physics video podcast looks at how you can utilise a cheap telescope and a camera or video tripod to get a decent view of the heavens. This year is the International Year of Astronomy (IYA) and if you don't already own a telescope then you have the opportunity of purchasing a ridiculously cheap, good quality telescope, the Galileoscope, from www.galileoscope.org

This physics video podcast looks at the components in a microwave oven, and the basic physics principles involved. ie the forces experienced by moving charges in magnetic fields. I show the magnetron, transformer, capacitor, and electric motors.

This physics video podcast 'stability (video) june 11 07' looks at the concepts of centre of mass and centre of gravity and how these relate to the stability of objects. I have used an interactive whiteboard/capture device (MIMIO Xi) to capture my whiteboard notes. Thanks to Erin Hagerty and Jaemes Shanley at www.mimio.com for their assistance.

This physics video podcast 'investigating black holes (video) april 16 07', looks at how you can determine the mass at the centre of a virtual black hole. You will get an appreciation of the 'stiffness' of space by following the instructions in this physics podcast.

This video physics podcast 'reaction forces (video) march 4 07', looks at how we can resolve a force into its components and determine the magnitude of the normal reaction force, and explains what causes the existence of the reaction force.

This audio podcast is the soundtrack for the video podcast 'reaction forces (video) march 4 07'. It looks at how we can resolve a force into its components to determine the magnitude of the normal reaction force, and explains what causes the existence of this reaction force.

This video physics podcast looks at some simple experiments conducted by Galileo, and by my students, that can provide sophisticated analysis of physics concepts. Hopefully this episode conveys the impression that our universe is based on mathematics, and measurements can change our way of thnking.

This physics video podcast looks at the force that produces circular motion. It explains that this centripetal force acts towards the centre of the circular motion and debunks the concept of the imaginary 'centrifugal' force.

This episode is the audio track for the physics video podcast 'circular motion (video) feb18 07'. It looks at centripetal force and its related acceleration, as well as proving the non-existence of centrifugal force.
