a stable mount for your telescope (video) june 19th 2009

Fri, 19 Jun 2009 11:51:58 +0000

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

stability (video) june 11 07

Mon, 11 Jun 2007 22:39:14 +0000

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.

measurement, mathematics and physics (video) feb 25 07

Sun, 25 Feb 2007 05:13:14 +0000

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.

circular motion (video) feb 17 07

Sun, 18 Feb 2007 01:58:22 +0000

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.
