Notes
1John Maynard Keynes, ‘Newton, the Man’, in The Royal Society Newton Tercentenary Celebrations (Cambridge, 1947), pp. 27–34.
1Leonard Digges (c.1515–c.1559), wrote A Geometrical Practise, Named Pantometria, which was finished and published by his son, Thomas, in 1571.
2R. T. Gunther, Early Science in Oxford, (1932), II, 293. The new Oxford DNB, published in 2004, says: ‘claims have been made that Digges devised a reflecting telescope; there is no evidence that [this] led to a working instrument’.
3Francis Johnson, Astronomical Thought in Renaissance England: A Study of the English Scientific Writings from 1500 to 1645 (New York, 1937; reprinted New York, 1968). A typical sleight of hand appears on p. 228: ‘Harriot took some sort of telescope with him on his expedition to Virginia in 1585, there is no reason for assuming that Harriot owed his telescopes to foreign inventors’. From his True Report (1588), Harriot had taken Burning Glasses and Perspective Glasses (i.e. lenses and mirrors).
