This exhibition was dedicated to the 200 year memory of Georg Christoph Lichtenberg who was born in 1742 and died in 1799. He attended High School in Darmstadt and studied mathematics and natural sciences in Goettingen from 1763-1766. In 1770, he became an extraordinary professor of experimental physics. Lichtenberg was known for his spirit-rich aphorisms and scientific papers. These aphorisms include among others. 1) A half new invention with a completely new name. 2) Exceptions are not always confirmation of the old rule; they can be also the harbingers of a new rule. 3) It is strange that only extraordinary humans make the discoveries, which seem after so easy and simple; this presupposes that for the simplest project, conditions of the things to notice require very deep knowledge. -- Source of annotation: Marvin or Ruth Sackner.
