Have you ever tried to put all your relatives in a single chart(Family Tree)?
All of a sudden I got a sparkle to build a Family Tree. A family tree of my own. When I searched on the Google, I came across many websites which provide a way to build a Family Tree.
After a short comparison I found that www.tribalpages.com which suit my requirements. You need to register first to build your website.
This website provides an easy way to build a family tree in simple steps. Once you add the names of your relatives, you would be able to find the relationship of any two individual persons in a tree like structure.
You can also add the names, birth days, anniversaries and other important/miscellaneous notes for each person.
If you don’t want these information to be shared/published to public, you can still restrict the site(Family Tree) you built by providing a password. (When you want to share with your friends and relatives share the password too).
You can also add photos to get a photo tree of your relatives.
The entire service is free of cost provided by www.tribalpages.com. There are few more advanced features for paid users on report generations.
So start building a Family Tree of your own. In a matter of one hour you can build your own Family Tree. It would definitely be a a fun filled/useful time pass.

False Proof is one of the concepts in Mathematics. This is a quite interesting area. One of my Mathematics professor started his first class with the following question.
Can you prove 1 = -1?
We all said nope.
Then he went to the blackboard and wrote the following proof.
Version 1:
Amazing. Isn’t? This is called False Proof.
There is one more way to prove 1 = -1.
Version 2 :
Now let us see, how is this possible?
Let us take the first proof (False Proof)
The rule is generally valid only if at least one of the two numbers x or y is positive, which is not the case here. Alternatively, one can view the square root as a 2-valued function over the complex numbers; in this case both sides of the above equation evaluate to {1, -1}.
How about the second version? Is that true? The answer is false again. Below is the explanation.
The equation a bc = (a b )c, when b and/or c are fractions, is generally valid only when a is positive, which is not the case here, leading to an invalid proof.
