The full title translation is from p. 60 of James R. Voelkel Johannes Kepler and the New Astronomy Oxford University Press. Kepler was driven to this experiment after observing the partial photo voltaic eclipse at Graz, July 10, 1600. He used Tycho Brahe’s technique of statement, which was to project the image of the Sun on a chunk of paper through a pinhole aperture, instead of wanting directly on the Sun. He disagreed with Brahe’s conclusion that total eclipses of the Sun have been unimaginable, because there have been historic accounts of complete eclipses. Instead he deduced that the scale of the aperture controls the sharpness of the projected image (the bigger the aperture, the extra accurate the image – this fact is now basic for optical system design).
Our capacity to supply a voice for scientists and engineers and to advance science is dependent upon the assist from individuals like you. “A pretended or spurious science; a group of associated beliefs concerning the world mistakenly regarded as being based on scientific technique or as having the standing that scientific truths now have,” from the Oxford English Dictionary, second version 1989.
