Margaret Cavendish (1623-1673) was an English aristocrat, scientist, writer and philosopher. The following interesting and charming poem by Cavendish I found in A Quark for Mister Mark: 101 Poems about Science, edited by Maurice Riordan and Jon Turney (Faber & Faber, 2000).
Of many Worlds in this World by Margaret Cavendish
Just like as in a Nest of Boxes round,
Degrees of Sizes in each Box are found:
So, in this World, may many others be
Thinner and less, and less still by degree:
Although they are not subject to our sense,
A World may be no bigger than Two-pence.
NATURE is curious, and such Works may shape,
Which our dull senses easily escape:
For Creatures, small as Atoms, may be there,
If every one a Creature's Figure bear.
If Atoms Four, a World can make, then see
What several Worlds might in an Ear-ring be:
For, Millions of those Atoms may be in
The Head of one small, little, single Pin.
And if thus small, then Ladies may well wear
A World of Worlds as Pendents in each Ear.
Curiosity led me to count the number of poems in A Quark for Mister Mark that are by women; out of 101 poems there are 24.
