My friend Ernst Georg Beck died this week after a long battle with cancer. Ernst Beck was a biology teacher at the Merian technical grammar school in Freiburg and co-founder of the European Institute for Climate and Energy (EIKE) in Jena. He was a teacher of the old school, whom nobody could lead up the garden path. If a statement of politicians did not fit into its solid scientific conception of the world, he examined it by intensive study of international technical literature and, if possible, by own experiments. His website www.biokurs.de is still a treasure trove for everybody, who prepares for examines or finding answers to current scientific questions.
