A marvel of a movie. A must see. Well done. Of course, as usual in
hollywood type renderings (or rather bollywood type in this case), there
is quite a bit of exaggeration going on (which of course is necessary for
a movie). One can look up the amazing
Shakuntala Devi here. She could compute the 23'th root of a 201 digit
number in 50 seconds and compute
7,686,369,774,870 × 2,465,099,745,779 in 28 seconds which was a world record.
In the movie the computation times are cut down.
