Correct my writing please.

You read that article from Scientific American, and you see the word "postulate". while you know the meaning, you're still not sure how you can use it yourself, like you want to know its difference from "conclude", as an instance. So you happily type inside Google "Postulate vs Conclude" and Google suggests some useful and non-useful addresses. Let's assume that among that crazy number of links and websites, you finally find the answer of this amazingly difficult question. Now, when you go back to the article, do you really think that you'll be using it at some time in the future? Most of the times, the answer is an instantaneous "No" or "No, I'm not sure how I'm gonna use it yet! Maybe I should do some more research?!" So you see, you've just wasted your time on something useless with an obscure underlying aim. Of course one which is not any more unknown to you and me right now.
