Today is 88th birth anniversary of mathematics wizard Shakuntala Devi, known as the “Human Calculator”.
Google created a Doodle on her 84th birthday to honour her…
As a child the only source of Mathematical puzzles for me were the books by Shakuntala Devi (before I discovered Martin Gardner, Sam Lloyd and W. Sawyer, Alex Bellos et al).
Fields Medal winning American mathematician of Indian origin, Manjul Bhargava explained in one of his talks the difference between math savant and a math genius. By his definition Shakuntala Devi would be called more of a Math savant, and not math genius; nevertheless she is very popular and inspiring person for lot of young students who love mathematics.
