Event description

In the present century, perpetual motion and perpetual motion machines have a leery reputation. They have been outlawed by the rise of the scientific concept of energy in the nineteenth century.

In Leonardo's day, perpetual motion machines were not seen as contrary to the way nature worked. Moreover, the Universe as a whole was believed to rotate about the Earth once every 24 hours. This left open the possibility that perpetual circular motion could be created on Earth. Perhaps forces from the Heavens could drive terrestrial machines?

The conference will examine the starting point and trace some of the changes in the understanding of machines and of the natural world that gradually ground down such hopes.

We shall consider clockmakers' efforts to reduce friction and shall examine encounters between various machines and current scientific theories, up to the time (in the mid nineteenth century) when it became possible for an engineer to write a history of perpetual motion as if the matter were now settled. That did not put paid to claims it was not, but we end with a machine that is apparently proposed as a puzzle rather then a proof.

This conference is organised by the Royal Institution and the Leonardo da Vinci Society. For more information, please see the following site, or contact jv.field@hart.bbk.ac.uk.
