Friday 29th April, 12:15 Leó Kristjánsson is holding a lecture about Iceland spar in East Iceland, its use and importance. Leó Kristjánsson is geophysicist at the University of Iceland. The last 16 years he has collected data about the use of Iceland spar crystals in science. Most of these crystals came from Helgustaðir, East Iceland until around 1900. The crystals contributed a lot to the discovery of optics and more. With the discovery of the so called Nicol-prism that is built of 2 Iceland spar crystals that were used in all optical instruments in different fields of natural sciences, it is sure that Icelandic Iceland spar accelerated many technical progresses and discoveries that seem self-evident to mankind today. Everybody welcome.
