Dear all, I strongly suspect the alleged quote is not from Faraday, but a slightly changed phrasing of a famous quote by the experimental physicist, physiologist and philosopher Ernst Mach, who wrote in 1872 (in: Die Geschichte und die Wurzel des Satzes von der Erhaltung der Arbeit, p. 46): "Die Theorien aber sind wie dürre Blätter, welche abfallen, wenn sie den Organismus der Wissenschaft eine Zeit lang in Athem gehalten haben."

Hello all, A library patron has asked for help verifying this quotation, supposedly by Michael Faraday: "I hold my theories by my fingertips so that the least breeze of fact might blow them away." Much searching online and in print hasn't turned up a reference. Do you have any leads or thoughts on sources to consult? Thanks, Michelle
