Jiffy
In physics, it is the time taken by light to travel a cm in a vacuum.
In Computing, it is defined as a time period of 10 ms.
In electronics, it is the time taken by one cycle of an A.C. which is mostly 1/60 to 1/50 th of a second.
So next time when you use the phrase "in a jiffy", remember you actually take more time to speak the phrase than the context in which you used the phrase for. i.e. don't use this word. It is unjustified!
Learning is more sort of a one way co-ordinate similar to time. Just as time can flow in only one direction, in exactly the same way you cannot unlearn something that you have learnt. On trying to unlearn, you only become more conscious of what you are trying to unlearn.
Why is one sixtieth of a minute a second?
Ptolemy, when dividing a circle into smaller parts, he called one sixtieth part of the circle as 'pars minuta prima' and one sixtieth of that he called 'pars minuta secunda'. The same terms were then applied to the division of an hour.
Three laws of Robotics by Issac Asimov
1. A robot may not injure a human being or, through inaction, allow a human being to come to harm.
2. A robot must obey the orders given it by human beings, except where such orders would conflict with the First Law.
3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Laws.
J. J. Thomson won the Nobel Prize in Physics in 1906, when he showed that electrons were particles.
His son, George Paget Thomson, won the Nobel Prize in 1937, when he showed that electrons were waves.
The Government of India has declared December 22nd as the "National Mathematics Day" in honour of the birthday of Srinivasa Ramanujan.
Nicolas Chauvin was a soldier of the French Empire, so vociferously and unceasingly aired his veneration of Napoleon Bonaparte that he became the laughing stock of the entire European continent. Thereafter an exaggerated and blatant patriot is known as a chauvinist.
