MIDSEMS time!!....so this is another way to do more lukkha when u hav no interest to mug (especially after infi mugging u screw up ur paper...:D)...well as it is apparent that how much I am out of mood to mug..:D....when I started writing this my mom called me..After little talk with her I finally decided to delve into heat transfer having no other choice (even though it has got infi applications like central heating ,refrigrator etc) ....I wish one day I am also like Charlie "Nuwanda" Dalton and do wat ever i feel like doing rather than things which i forced to do.....anyway i think its high time to start mugging....:D
