If you drive an electric car more than trivial distances between charges, you likely appreciate a state-of-charge meter (that is, what would be called a fuel-gauge in a petrol car) that is accurate. When it reports a range of 30 km, you do want to be sure it will actually do this distance. If you […]

No hot toast, no porridge. […]

I am a physicist (yes!) but also, at […]

Damp conditions equals a damp demonstration. But yesterday was really good. No Van der Graaf generator needed – […]
