Think it over

“Ideally, what should be said to every child, repeatedly, throughout his or her school life is something like this: ‘You are in the process of being indoctrinated. We have not yet evolved a system of education that is not a system of indoctrination. We are sorry, but it is the best we can do. What you are being taught here is an amalgam of current prejudice and the choices of this particular culture. The slightest look at history will show how impermanent these must be. You are being taught by people who have been able to accommodate themselves to a regime of thought laid down by their predecessors. It is a self-perpetuating system. Those of you who are more robust and individual than others will be encouraged to leave and find ways of educating yourself — educating your own judgements. Those that stay must remember, always, and all the time, that they are being moulded and patterned to fit into the narrow and particular needs of this particular society.”
― Doris Lessing: A British novelist.

How can one learn Physics/Science?

Over the last couple of days, quite a few students have sought tips to grasp the concepts in Physics. I am reproducing an earlier blog for their benefit……….
Read on…..
Although a lot can be said and discussed about the same, a very simple and straight forward answer comes to my mind.
By critical thinking alone!
The following excerpts from Feynman’s lecture in Physics say it all.
“A poet once said, ‘The whole universe is in a glass of wine.’
It is very true.
Look at a glass of wine closely enough to see the entire universe.
 
 It contains:
  • the twisting liquid which evaporates depending on the wind and weather, the reflection in the glass; and our imagination adds atoms.
  • a distillation of the earth’s rocks, and in its composition we see the secrets of the universe’s age, and the evolution of stars.
  • a  strange array of chemicals in the wine? How did they come to be?
  • the ferments, the enzymes, the substrates, and the products.There in wine is found the great generalization; all life is fermentation.
Divide this glass of wine, this universe, into parts — physics, biology, geology, astronomy, psychology, and so on to all other branches of knowledge.
Remember:  Nature does not know it!
Each one of has to think and learn on his own. After all  Science has its origin and existence only in our ability to think and analyze.
Not interested?
Enjoy: drink wine; throw the glass  and forget it all”.
THE MESSAGE IS LOUD AND CLEAR.

 No thinking! No Science!

OR

Listen to the message in this melodious style!
