Uncertainty Principle - Few Thoughts

The "Uncertainty Principle" proposed by Werner Heisenberg in 1927 states that we cannot precisely measure both the position and momentum(velocity) of an electron.This is because we normally observe things as light(photons) bounce back from that object.To observe a tiny particle as an electron we need electromagnetic waves of smaller wavelength like gamma radiations.Now photons of the gamma radiation colliding with a tiny electron can alter it's position and momentum introducing a factor of uncertainty into the measurements.

Paleolithic Cave Paintings - A 20,000 Year Project - The Stream of Learning.....

Prehistoric cave paintings... by hearing this term the "Bison in Altamira Cave" comes into my mind.One of the earliest signs of human creativity.I still remember that black & white picture in my sixth standard history book.Looking at that picture I used to visualize a shadowy dark cave with almost extinguished fire in the centre,group of men dressed in animal skins,talking in weird languages,painting bison in that psychedelic studio.Later I have found several references to this painting including Satyajit Ray's last movie "Agantuk".This has been always a topic of interest and wonder to me.

Few thoughts on language

"Today late afternoon in the illusive shades of the twilight I saw a beautiful lady dressed in white.Someone like the Lady of Shallot.What to say.. Belle de Jour?.I am just not able to find right words to describe"
The above statement is interesting but vague.It tells something at the same time hides away many things.Many of us has come across such a situation where we do not find the right words to express or find that the words we have used are not enough to express what we actually felt.Also there are many occasions where we say something and it gets interpreted in an absolutely different manner.So what ever be the language the words fall short or becomes vague to portray our thoughts in satisfactory and unambiguous fashion.
