I always wondered what life was like in the time of the sundial - was it more vague, less precise perhaps? It must have been a convention of metrologists that brought that vague time to an end. This is a very interesting piece on the science of measuring and measurements; while it sounds like an incredibly dry topic, it isn't. The piece is full of anecdotes well suited for the layperson. Find out what daphnias are and why they are important to measurements. How many daphnias can one fit on the head of a pin? Well done.

Can you _imagine_ getting an assignment to cover a legal metrology conference? The thought causes a villainous bile to rise in my throat, slowly choking my will to live. A credit to reporters everywhere, producer Alan Coukell has fashioned an exciting, dynamic, and humorous piece about this very subject. All radio should be this lively. The narration is punchy, the interviews are varied and informative, and the mix is playful. My hat is off. Outstanding.
