RE: WOX Travel Contest | Week 8 - Qutub Minar Complex, New Delhi
Thanks for another very interesting post. This time you have given me material for further study. I read more information about this famous complex on Wikipedia. As a chemist, I was especially interested in an iron pillar that does not rust. It turns out that a passive protective film has formed at the iron-rust interface. I am familiar with this phenomenon. Thanks again for such a cool post.
I agree that history is not my strong point so I have missed a few points! But as I said, everything is available online so people interested in knowing more might get it from the internet. I have my main pen drive back in Canberra that I will find when I reach there in next 7-8 weeks. Thanks for your kind words for my ordinary work.
