MANY READERS – ESPECIALLY those with some knowledge of physics – will have heard of the German Werner Heisenberg (1901-1976), who is well known for his famous Uncertainty Principle that relates to quantum physics. Because of my uncertainty about what exactly this principle expresses, I will let you look it up on Google or elsewhere.

One thing I was not uncertain about was seeing a café called Heisenberg in Chiswick’s Turnham Green area. As it was nearly 11 am, I was certain that I needed a cup of coffee, and what better place to have it than a place named after a person who ‘discovered’ uncertainty. The café is small but quirkily decorated and the coffee it served was very good. We drank from disposable cups, which bear the motto:

“Perfection cannot be measured as explained by the Heisenberg theory. However, this is the closest you’ll get to the perfect cup of coffee.”

Although I am uncertain whether the second part of this is true, I am certain that when I am next in the area, I will try another cup of Heisenberg’s coffee.
