From Allen Reynolds
In his letter, Doug Legge proposes the light bulb as a universal symbol for science (21 January, p 29). The incandescent bulb is so last century, and his screw fitting would be out of place around here – our bulbs usually have bayonet connectors.
Could it be that we cannot have a universal symbol, since science is the act of striving to understand, while a symbol represents something that is well understood?
