The Useless Knowledge
Tuesday, September 9th, 2008Long time ago, a friend of mine, who frustrated with math problems, asked my math teacher.
“Sir, I want to be a writer when I grow up. Do I really need all this differentials and factorization? When will I need it in the future?”
He answered, “Well, imagine you come home alone in the middle of the night after your books signing, and someone tries to mug you and said, “Factorize x2 - 4 or die!”. You will be glad that I teach you about factorization then.”
It’s a lame sample, but who knows what might happen in the future. Someone said that we only used 10 percent of what we learned in high school or university. I agreed with him. But, we never know for sure which ten percent, we are going to need later.
