Description: | Large version of 'classic' demonstration. 7 ivory balls each about 1 inch in diameter suspended from double strings, wooden base with brass columns. Copland's 1823 inventory includes '9 ivory balls, of sizes for collision (1769)' and it is possible that this, or at least the balls, have a long pedigree. William KNight purchased a 'collision frames with Doric columns' from Jo. Falconer, a local joiner, for £-/11/10 in 1823 for demonstrating to the class and this may be the result, with possible updating. | License: | http://www.abdn.ac.uk/historic/Copyright_terms_conditions.shtml | Publisher: | ABDNP University of Aberdeen, Natural Philosophy Collection of Historical Scientific Instruments | Rights holder: | 47718 | Temporal: | 1775-1823 | Source: | University of Aberdeen | Creator: | unknown | Identifier: | http://calms.abdn.ac.uk/Geology/dserve.e... | Go to resource |
