I stumbled across an old Monty Python sketch the other day that plays with words pleasing to the ear (‘woody’) or displeasing (‘tinny’). I chortled (nice woody word) but then started thinking about wood and science - we don’t often associate the two and we’re culturally conditioned to associate wood with words like ‘old’:
But appearances can be deceptive as the Mosquito aircraft demonstrated. It may have resembled its alloy contemporaries of World War 2 but its sleek exterior cloaked a strong, lightweight structure of balsa, birch and spruce.
