"Don't stare at the ceiling!" is a common admonition teachers use with students staring vacantly into space. That is because nothing says "daydreaming" like a student staring at a ceiling. It brings out the worst in teachers, and rightly so. And while we're all for paying attention in class, sometimes a little off-hours daydreaming can be a good thing.
It can be a good thing for Science, that is. Idle thoughts can produce lateral insights, which in turn become scientific breakthroughs, discoveries or inventions. Seeing the commonplace with fresh eyes is an Art - but it is an Art that spawns Science.
When something is new, it excites our senses and holds our attention; this changes when it becomes familiar. Ever notice how the excitement of taking a window seat dwindles after the route becomes familiar? Or the excitement of seeing a rainbow, or the falling snow, or a sunset?
When the mind is the disease, absent-mindedness is the cure! The laws of Nature are hidden because familiarity prevents us from seeing them. Here's how a great Science discovery resulted from a certain somebody staring at a ceiling:-
We are not sure just how he verified this discovery. Maybe he first used his own pulse, then realized that the interval between any two beats was not uniform; or maybe, the excitement of discovery caused his pulse to race, so he abandoned the approach. Maybe he used a musician-friend's acute sense of timing to measure the duration of chandelier swings - we don't know for sure.
What we do know is that Galileo discovered the single most important (and surprising) aspect of suspended masses - their isochronism or "same time"-ness. He discovered that a pendulum's time period is independent of the width of swing, or the weight of the suspended object. This meant that the time of oscillation for a pendulum would remain the same until it stopped, and this caused a revolution in time-keeping. Further experimentation helped Galileo derive this formula for the period T:
T = 2(pi) x Square Root(L/g)
Scientists who came later built on this knowledge and created devices based on the use of a pendulum, and the pendulum slowly became the time keeping heart of our civilization. Foucault noticed an even more interesting aspect of pendulums, but that is a different story...
