Used by Kelvin in class demonstrations. Kelvin had a great interest in things which rotated since he was keen to model the theories which he constructed for the "vortex atom". This is a friction drive instrument in the form of an enclosed top. The octagonal equatorial knife edge allowed it to be balanced on edge on a glass plate either stationary or skating across the glass. There are also two subsidiary knife edges attached to the underside of the equatorial edge which allowed the instrument to be set on a stand or gimble. | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SCIENTIFIC COLLECTION : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
