The Science museum (London) is running a poll to decide which out of “10 scientific objects that changed the world” is most favoured in the world- All of the things have a little spiel on them, and inventions include items such as Stevenson’s Rocket, the model T ford and the electric telegraph. It also includes some more recent inventions/discoveries such as penicillin, but compared to the steamy goodness of a clanking engine belching fire and steam, what chance do a couple of microbes have ?
