Bio: "I studied physics (a long time ago), then trained as a science and maths teacher. After that, I worked at London’s Science Museum in the Education Unit – and in the museum’s flagship interactive gallery, Launch Pad.

I left the museum in 1991 to write science and technology books and to write and perform science shows in museums, libraries and schools. Recently, I worked for two years on the development of science television programs for BBC Scotland."
