-
he's over that way-- so Robert Boyle wrote
-
this first important book in chemistry,
-
New Experiments Physico-Mechanical: Touching the Spring of Air.
-
So you know Boyle's Law,
-
how pressure and volume change,
-
that air in a piston acts like a spring.
-
So PV is a constant; that's Boyle's Law.
-
So he developed this science on the basis of a new instrument,
-
the pneumatical engine, which was built by Robert Hooke,
-
the guy we quoted.
-
And there's a picture of the air pump here with that crank on it,
-
and so on to pump things in or out of that bulb.
