sun burns faster when convex side of plano-convex lens is towards him

Categories: Personification

An example of personification in historic science writing,

"In my first lectures I shewed how a necessary account of ye true length of a yeare occasioned all the enquirys in Astronomy, first the Suns motion & its inequalities, next the lunar Periods. & her Anomalies then her distances

I find it now more convenient when I goe to light my pipe of tobacco at ye Sun with a plano convex glasse, to turn the convex side towards him then the plaine, for then all the parallel raies meeting the Axis in a lesse length must needs burne faster than when the plaine side is towards him & I assure you in my opinion, as oft I trie it, the experiment confirmes what I had learnt by speculation & Theory…"

John Flamsteed letter of 1861, quoted in Eric G. Forbes (1975) Introduction, in The Gresham Lectures of John Flamsteed, London: Mansell Information Publishing Ltd.

By tradition, the moon is female and the sun male.
