Georg C. Lichtenberg Quotes
When an acquaintance goes by I often step back from my window, not so much to spare him the effort of acknowledging me as to spare myself the embarrassment of seeing that he has not done so.
Lichtenberg, Georg Christoph. The Waste Books. Translated by R. J. Hollingdale, New York Review Books, 2000.
Georg Christoph Lichtenberg was a German physicist, satirist, and Anglophile. As a scientist, he was the first to hold a professorship explicitly dedicated to experimental physics in Germany. He is remembered for his posthumously published notebooks, which he himself called Sudelbücher, a description modelled on the English bookkeeping term "scrapbooks", and for his discovery of tree-like electrical discharge patterns now called Lichtenberg figures.
