Mir titles is a feeling. It's nostalgia. It's childhood for many including me. The books are excellent written by some of the finest of their times talking to the lowest highschool level student or even a child and making him or her understand fully what all is going on. Indians love Mir.

My favorite author is Landsberg. He is in Mir titles. He got defeated by our main man C V Raman by 2 weeks to publish the same research (independently) which got C V Raman the only Physics Nobel Prize for India.
