When my younger son, Abhinav, requested me for a blog of his own as a present for his 9th birthday last December, I was quite sure it was a passing phase. But even after 6 months when he wouldn't give up, I created one for him. Looks like he loves blogging.
What does he blog on? Mathematics! No I am not joking! Have a look youself - Abhinav's Blog.
Please do visit his blog; leave a comment; he needs all the support he can get.
