Matt Johnson explains the Krebs Cycle, its discovery by a University of Sheffield Nobel Prize winner and its role in endurance sports such as cycling.

Jonathan describes the construction of a model of the C60 molecule.

The UK coast is constantly being bombarded by sea waves.  There is a massive amount of power available from these waves.  Jonathan describes three different ways of generating electrical power from water waves.

A short video explaining how transistors work.  At the heart of our high-tech society with radios, mobile phones, computers and space exploration are tiny electronic components called transistors.  They have revolutionised electronics and in the pr....

A short video on solar cells explaining with accompanying information sheet. How they work and how Jonathan uses solar power at home.

With some simple circuitry and a homemade hand powered generator Jonathan makes AC and DC electricity that could be used for charging a mobile phone or attaching to a wind turbine.

Jonathan makes some simple paper windmills/turbines and experiments with a simple generator to power house hold devices such as torches, calculators and even a radio.

Jonathan shows us with a cheap and simple homemade demonstration how your mobile telephone generates radio waves in order for you to use it to communicate.  As you will see you can use this method to explore many aspects of your mobile phone!

In October 2010 the Nobel Prize for Physics was won by Andre Geim and Konstantin Novoselov at Manchester University for their work on graphene but if you are left wondering just what graphene is then watch this video. Jonathan explains all.

Jonathan explains what graphene is and how it fits into the revolution in carbon science.

This short video shows one of the demonstrations for the Physics SEPNet exhibition - "Who will keep the lights on?" which travelled around the southern UK from February 2009.  We describe and explain the electrical generator demonstration which Jona....
