Galileo

We've mentioned Galileo before on this Blog but there's no reason why we can't mention him again. So here goes: Galileo Galilei (1564–1642) famous Italian mathematician, physicist and philosopher from Pisa.

In 1583, Galileo entered the cathedral in Pisa. Some men were carrying out some repairs and someone accidently set in motion a heavy lamp which was suspended from the ceiling. The lamp kept moving to and fro, to and fro, backwards and forwards. Galileo sat there on a pew and watched it move backwards and forwards ... backwards and forwards "you are feeling sleepy, very sleepy, your eyes are getting tired, your eyelids are heavy ..."

Sorry ... I got distracted by my own writing there. Exciting what? I'm so good at suspense that sometimes I surprise myself. Anyway, back at the suspense.

The suspended heavy lamp, (see what I did there with the word suspense?). As I was saying, the swinging lamp set Galileo thinking. He was easily amused. 

He noticed that the to and fro swings seemed to be timed almost the same. He put his fingers on his left wrist and counted his pulse. To his surprise the swinging of the lamp was almost the same as his pulse.

It was a Eureka moment.

He got in touch with a Swiss friend of his called Role the Tenth because he was the tenth son of a man called Role who called all his children Role. Anyway, Role the Tenth shortened his name to ROLE X. He was so excited by Galileo's discovery that he and Galileo invented a watch which works like a pendulum. It was the first time that pendulums were used for time keeping purposes.

People wore the watches on their wrist and went around swinging their arms to and fro, to and fro, to keep the watch working. Unfortunately, in doing so they often hit other people in the eye or in the face causing a lot of injuries. So the pendulum watch never took off as a successful idea. This did not deter Role X who went on to invent much better sought-after watches.

Back to Galileo, however, who also undetered by his watch experiment went on to invent the telescope. He took a long tube and put a glass lens at each end et voila.

Galileo placed the telescope by the window high up in his house in the attic and, remembering his adventure with Role X years previously, he started swinging the telescope to and fro, to and fro. He moved it to the left, then he moved it to the right, and then the left again.

And this is what he saw.

And this ...

And also this ...

Of course, those were the days before curtains in windows were invented. So Galileo put his telescope to good use by watching his neighbours' goings on all evening.

He was there for so long that his wife grew a little worried. She switched off the radio in the kitchen where she was listening to "Woman's World"; a popular programme at the time, and went up in the attic.

"What are you doing?" she asked Galileo in Italian. (She did not speak English, but even if she did, it was pointless speaking to Galileo in English because he did not know English either).

"Oh ... I am looking at the heavenly bodies" he lied as he swung his telescope upwards towards the sky.

His wife was suspicious about this but said nothing. It was after all a very cloudy night with not even a moon, so there was no chance he would have been watching "heavenly bodies" - not unless they were mooning him from their windows!
 
The following day, whilst Galileo was out of the house buying pizza for lunch, she went up to the attic and put a little ink on the end of the telescope from which you look. She knew from listening to the weather forecast on the radio that that very evening would also be very cloudy and therefore there was no point in watching up to the sky for planets or stars.

That very evening, Galileo pretended to be tired and went to bed early. As you've guessed, he spent all night watching his neighbours again.

The next morning he woke up with two black rings round both eyes. That's because he had gotten very tired watching for "heavenly bodies" with just one eye, so he alternated eyes to have a rest.

His wife challenged him and he confessed and told her the whole truth. 

Rather than be angry, which is what you would expect under the circumstances, or over the circumstances even; the clever wily lady invented binoculars to save one from having to change eyes when watching whatever it is you want to watch.

Which goes to show:  

Man might think he is clever. But in reality woman is much cleverer than him.
