Are you better than your mom in applying physics and its concepts? I am certainly not.
Here are two such incidents that occurred to me....
1) After coming to bangalore, i started cooking and my mom gave me instructions that when cooking daal , add salt after the dal is cooked. I have been wondering why. But it occured to me that the boiling point of water is increased when we add impurities, especially salt. I googled and found out that the boiling point of sea water is 103 odd degrees. My mom never knew this but she knew that adding salt delays the cooking of daal. Howdy hell i didnt know that... and i claim that i got 120 out of 120 in phyiscs in my 12th(and 30/30 in practicals :P).
2) This incident made me think that my mom(or her mom, or her grand mom) discovered things that newton proclaimed to have discovered. Whenever i had some hot water in a bucket, my mom insisted me to add some cold water to it immediately. I asked her why and she said that because of this the hot remains hot for a longer time , even if you left the hot water just like that. Years later i read that newton's law of cooling is exactly the same. It says that the rate of cooling of a body is directly proportional to the difference between the temperature of the body and its surroundings.
You have the answer now, are you still better than your mom in application??

Sirish..Liked the examples froom Physics!
I didnt know example no 1 myself.
good one .. you reminded me of two things ..
ONE :- i suck at physics and TWO:- Einstein must have listened to his mum when he was young .. from the look of things, it pays to listen to your mom .. :)
siri.. lovely ra... the title dragged me... so its jus like this.. we apply physics before we truly learn it n all the credit goes to the very special...mom's university:)
