Lippmann's Colour Photography |
The next Tools of Science meeting will be held at 6pm on Tuesday May 6 in Parnell (7) LR222 The speaker will be Dr Margaret Wegener and the topic Lippmann's Colour Photography One hundred years ago, the Nobel Prize in Physics was awarded for a "method of reproducing colours photographically" to Gabriel Lippmann. Today, Lippmann is not famous, and his method is not the basis for colour photography as we commonly see it - so was 1908 a dud year for the Nobel committee? Dr Wegener will argue for the significance of his work. Lippmann photos are remarkably similar to a type of hologram, so were a pre-cursor to the field of holography. The consequences of his work also include recent research into colour produced with periodic structures. Dr Wegener will explain the physics that links these (which relates to the wave nature of light), and show examples. Dr Margaret Wegener is a lecturer in the Physics Department at The University of Queensland, teaching both aspiring physicists and physics service courses. Involvement in physics education research, and activities promoting the physical sciences in the community are other facets of her work. She is deeply interested in the interrelationships between science and the arts. An art gallery exhibit inspired curiosity about holograms, which was fulfilled during her PhD at UQ, when she used holography to investigate gases moving at high speeds in a Superorbital Expansion Tube. |
