Krakin Posted April 6, 2014 Report Share Posted April 6, 2014 Just a quick funny that I came across. Quote In 1903, Rene Blondlot, a respected French physicist, claimed to have discovered a new form of radiation he called ‘ N-rays ’ . (This was shortly after the discovery of X-rays by Roentgen, so rays were in the air, as it were.) This invisible radiation was apparently mysteriously refracted by aluminum prisms; but the crucial factor was that its presence could only be shown by subjective assessment of the brightness of an electric arc allegedly affected by N-rays. No objective measurement appeared to be possible. To Blondlot, and at least 14 of his professional colleagues, the subtle changes in brightness were real, and the French Academy published more than 100 papers on the subject.Unfortunately N-rays were completely imaginary, a product of the ‘ experimenter-expectancy effect. This was demonstrated by American scientist Robert Wood, who quietly pocketed the aluminum prism during a demonstration, without affecting Bondlot’s recital of the results. After this the N-ray industry collapsed very quickly, and while it was a major embarrassment at the time, it is now almost forgotten. The conclusion is inescapable that it is quite possible for large numbers of sincere people to deceive themselves when dealing with subjective assessments of phenomena. That shows you that you have to be very cautious when you view another person's testing, and that just because there is a following behind them doesn't mean it is true or even exists.Link to Douglas Self's book, Audio Power Amplifier Design Handbookhttp://www.amazon.com/Audio-Power-Amplifier-Design-Handbook/dp/0240521625 Edit: Fixes link to the book.

ModestDb Posted April 6, 2014 Report Share Posted April 6, 2014 Exactly why I heed all advice with skepticism, always.
