Ramanujan (2014) - A movie

Dear Reader,
Today I watched the movie Ramanujan (2014) , the only movie ever made about life of genius Indian mathematician Srinivasa Ramanujan, . Though it was in tamil but to one who worship him like a God , language was not a barrier. Well, thanks to english subtitles. It is really a very nice movie. Every Mathematics lover should watch this movie.
Also those who have not read his biography 'A man who knew infinity' by Robert Kanigel, should spare some time and must read that book.

Happy pi approximation day

Dear Reader,
Well, today is Pi Approximation Day.
Pi Approximation Day celebrates the mathematical constant π (pi). It is observed on July 22, due to π being roughly equal to 22/7.
The fractional approximation of π ,22⁄7, resembles the date July 22 in the day/month format, where it is written 22/7. Pi Approximation Day is therefore celebrated on July 22.
In geometry, pi is defined as the ratio of a circle's circumference to its diameter. July 22, often written as 22/7, is an appropriate day to explore pi, since 22 divided by 7 is an approximation of pi.
Pi Approximation Day is celebrated in a number of ways, including contests to memorize pi to the most decimal places, solving math problems involving pi, discovering the history of pi, ruminating on how life would be different without pi and—of course—eating pie.
So, enjoy this mathematical day ...
Amit Sir

What's the next number?

How would you continue the sequence 1,2,3,4,5,6,7,8,9?
The next number might be:
• 10, if this is the sequence of natural numbers;
• 1, if this is the sequence of the digital sums of natural numbers;
• 11, if this the sequence of palindromes;
• 0, if this is the sequence of digital products of natural numbers;
• 13, if this is the sequence of numbers such that 2 to their powers doesn’t contain 0;
• 153, if this is the sequence of numbers that are sums of fixed powers of their digits;
• 22, if this is the sequence of numbers for which the sum of digits equals the product of digits;
or • any number you want.
