Nigel Davenport: Sir Charles Pelham

Quotes 

• Sir Charles Pelham : How can you tell if a clock is running 5 seconds faster, or slower?

  John Harrison : My own pendulum clock is adjusted to one second a month.

  Sir Charles Pelham : O-ho-ho, no clock can be that accurate.

  John Harrison : Mine can.

• John Harrison : It's not just beautiful, it's divine: that's where the beauty lies, you see. Each note on the scale is calculated by mathematical formula, based on the circumference of a circle, you see.

  Sir Charles Pelham : Uh, almost...

  John Harrison : The step between each note is composed of larger and lesser intervals, each derived from pi. It is divine because for the first time we are listening to music as the Lord intended.

• John Harrison : Impossible, sir. Clock needs a pendulum. Can't take a pendulum to sea.

  Sir Charles Pelham : Not like you to say "impossible," John.

  John Harrison : No, sir.
