Wolfe’s Laws of Academic Research • First Law Unpublished data do not improve with time. • Second Law If you are first on the scene, it is easy to make discoveries. • Third Law The emotion generated in scientific discussion increases proportionally with the softness of the data being discussed. • Fourth Law If you join a parade, you become one of the marchers.

Wolfe’s Laws of Academic Research • Fifth Law They who skate on thin ice must skate fast. • Sixth Law Never stop in the middle of an experiment. • Wolfe’s Last Law Each new brick in the wall of knowledge will withstand the weight of all future knowledge only if it is the full truth. • Another Wolfe saying after winning the ASM Carski undergraduate teaching award in 1971 Research and teaching are like oars on a boat, you need to pull with each to follow a straight course (paraphrase)

Alessandro Volta 1745-1827

Flammable air • Ben Franklin wrote 1n 1774 to Joseph Priestly: “When I passed through New Jersey in 1764, I heard it several times mentioned that, by applying a lighted candle near the surface of some of their rivers, a sudden flame would catch and spread on the water....New Jersey having many pine- trees in many parts of it , I imagined that something like a volatile oil of turpentine might be mixed with the waters from a pine-swamp. but this supposition did not satisfy me… ” • Thomas Paine wrote that in 1783 George Washington tested this flammability on the Millstone river in NJ, having his soldiers disturb the sediments with poles and he “set the river on fire” with a torch John Dalton (1766-1844) collecting marsh gas. From: Parkes, Nature 401:217 (1999).

Carbon flow to methane – e. g. Cedar Swamp 1787 – Lavoisier: “hydrogenium carbonatrum” Volume of pistola ≈ 400 ml How much CH 4 should I add?
