# Google still depends on Yahoo! Huh!

**NFD Theorem**
**Google is not independent.**

**Proof**

Here we'll apply the indirect proof(also known as Proof by contradiction) informally.

For convenience, first assume that --

Google is independent. Totally independent. It doesn't use any service from nth party.(where n equals 3) ... ... (a)

Now it will be *sufficient* to proof this theorem if we can show that at least one third-party service is used in Google website.

We can consider the index page of Google Press Center. There exists a subscription offer(at the left-bottom side) so that people, any people can get updated news about that company via email. Note that the official mailing list of Google Press is **hosted by**Yahoo! Groups.

We get the *same return* from Google-Friends Newsletter service.

Now we know, all the email addresses subscribed to *Google Newsletter* are verified by *Yahoo Groups*.

Again, we know that

Yahoo! Groups is a service of Yahoo company. ... ...(b)

Yahoo and Google are different companies. ... ...(c)

It is clear from equation (b) and (c) that Yahoo Groups is not a service of Google, which contradict to our previous assumption.

Hence the only possibility, Google is dependent on third party service.
*(Proved)*

**Corollary**

# Google still depends on Yahoo, it's major rival.

# Google can't rely on their Google Groups 2 Beta which offers similar but better service to yahoo groups.

# Ishtiaque is very intelligent.

Ishtiaque I guess your recent exams has had an adverse effect on your mind :P .

Ooops!

That was awesome proof. And why teh hell Nobel prize for math does not exist man?? You really deserve one. But how did you manage to write Google in Yahoo STyle.. I am still pondering over that question.

:D ... man, u r something ... 'beshi joss' proof ... hmmm ... but, sigh, they dont have something for the mathmaticians ... the Nobel guyz i mean ... :P ... i wonder if the yahoo guyz and the google guyz are aware of your existence ...

great proof. I, being a math major, can totally see the beauty of your work there. Good job on proof. What is your major?
