On the anniversary of Napier’s death here are a couple of quotes regarding his logarithms;
Napper, lord of Markinston, hath set my head and hands a work with his new and admirable logarithms. I hope to see him this summer, if it please God, for I never saw a book which pleased me better or made me more wonder.
and Laplace said logs
…by shortening the labours, doubled the life of the astronomer.
