Mathematical Events - Square Root Day / Day of pi
How in the world are not as frequent religious and national holidays as well here in Serbia, people are forced to invent artificial. Among them are those which include matamatički holidays and Square Root Day and Pi Day number . This year it coincided both in early March, and that one went, the rest is to wait for another if you want to celebrate.
Day kvadratog root
This holiday is celebrated when the match is that the day of the month and the month I was the square root of the last two digits of the year. For example, the last Square Root Day was the third March (3:03:09). and the next will be for seven years and to 4 April (4:04:16).. How is this holiday praznikuje modulo 100 the number of years, each century, falls on the same day all nine times over a decade. Those who celebrate this holiday, that day is usually only eat meals that root vegetables cut into shapes with square cross section. If you have no idea how it looks, believe me you're not alone 
Day of pi (π)
Unlike the previous holidays, the number Pi has a winter and summer glory. Winter is celebrated on 14th March (eg 14/03/2009). and a rounding of pi to two decimal places, while summer celebration is actually an approximation of the constants in the form of fraction 22 / 7 and is celebrated on 22 July (eg 07/22/2009). As the calculation of the holiday does not take into account the years, praznikuje each year. Some go so far as to stand out and Pi minute (3:14. In 1:59) and Pi second (3:14. In 1:59:26), which represents the number Pi rounded to a certain number of decimal places. On this day are eaten round cakes, fruit pies, cakes and anything else that comes to mind has to do with a circle 
It is interesting that Albert Einstein was born in the 1879th The Day of pi.
/ Me hates maths, but this is interesting
And what do you say to something like this:

9876543 x 9 + 1 = 88888888
98765432 x 9 + 0 = 888888888
1 x 1 = 1
11 x 11 = 121
111 x 111 = 12,321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111 = 123456789 87654321
12345679 * 9 = 111111111
12345679 * 18 = 222 222 222
12345679 * 27 = 333 333 333
12345679 * 36 = 444 444 444

12345679 * 63 = 777 777 777
12345679 * 72 = 888888888
12345679 * 81 = 999 999 999
In this case, I'm going to sleep
Buffer overflow xD
