out-do yourself

Rainy Day~
Rained the whole afternoon.
Pray hard no more mould will grow on my bookshelf.
If not I will jus spray the bookshelf wif a layer of wax.
They seems indestructible.

Done wif Chem note on metals and some revision for differentiation test next week.
Wat is de practical use of dy over dx?
Integration is useful but wat does differentiation does?
Y Sir Issac Newton came up wif calculus?
His laws of unified gravity already cause so much headaches.
If I ever go back in time, I will make a durian drop on his head rather than an apple.
Ok that is my sis's idea.
She suggested me to replace wif "Ang mo durian" (soursop).
It is soft O.o
And I dun believe gravity exist.
Hope someone will unify gravity wif electromagnetic force soon.
And I will place a big letter "L" on Newton's forehead.

So much of complaining, lets talk abt something else.
Yea, eating ice cream on rainy day.
We bought ice cream from the uncle who so happen to sit at ur void deck, desperately finding customer.
He is surprised and had a shock look on his face.
Ahh weirdos.
Guess that is wat he was thinking at that moment.
The best part of eating ice cream in a rainy day is that it will melt at a slower rate.
Using chain rule we can calculate the rate of melting of the ice cream given the volume of it.
Dv/Dt x Dm/DV = Dm/Dt (rate of melting).
Maybe differentiation is useful after all.

I will continue to practise A math later on.
