# Strange words

| The somewhat unusual word "ken" is best remembered by a variant of a famous English poem:
|  | The Star or Twinkle, Twinkle, Little Star by Jane Taylor, 1806
|  | Original: |  | Physicists Version:
|  | Twinkle, twinkle, little star, How I wonder what you are. Up above the world so high, Like a diamond in the sky. |  | Twinkle, twinkle little star. I don't wonder what you are, 'cause by spectroscopic ken I know you are hydrogen.
| Ken (Scottish) To know, to recognize (German "Kennen"); To have an understanding of something.
