Anyone with an enquiring mind and an interest in science and technology is welcome whatever their background. Whilst some members have had a scientific education or career others do not.

Members often give a presentation on a topic which interests them and sometimes we watch relevant TV programmes or online videos such as TED talks. The subject matter is very wide ranging for example recently it has included Astronomy, Pharmacology, Developments in the Bicycle, Drones, Palm Oil, Green Energy and new materials.

We also allow time to discuss anything of scientific, technical or mathematical interest which has recently been in the news.

In a recent meeting the group looked at how the electric cables in a Hi-Fi set up could influence the overall sound. This led us to looking at some YouTube clips that explained how electricity flows in a wire and the electric and magnetic fields that are produced. It was somewhat sobering to learn that electricity does not flow like water in a pipe with a stream of electrons as we had been taught in school. At the end it was easy to see how the interaction of the magnetic/electrical fields that surround a wire could interfere to affect the musical signal passing through.
