THE CALENDAR TRICK

                                                                                THE CALENDAR TRICK


   

This trick makes you look like you've got the most awesome mental power. All you need is a calendar which has the dates lined up under the days of the week, so the numbers are arranged something like this:

  .     .     1     2     3     4     5

 6     7    8     9   10   11   12

13   14  15  16  17   18   19

20   21  22  23  24   25   26

29  30  31

The "9 number" trick:

  • Now to draw a 3x3 box around ANY nine of the numbers on the calendar.
  • Almost immediately you can say what the nine numbers all add up to!
  • See how long it takes your friend to check the answer on a calculator. (Yawn...snore...zzzz...)

For instance, let's say the red numbers are chosen.

  .     .     1     2     3     4     5

 6     7    8     9   10   11   12

13   14  15  16  17   18   19

20   21  22  23  24   25   26

29  30  31

They add up to 144.


THE SECRET: All you do is look at the number in the middle and multiply it by 9.

In this case the middle number is 16 and  16 x 9 = 144.

INVENTION OF ZERO

Image
 INVENTION OF ZERO The concept of zero has not always been around, however, the introduction of zero bought a lot of changes not only in math but also in the general life of people. Zero has so many different names, for example, ‘null’, ‘nil’, ‘0’ as a digit, ‘sunya’ in Sanskrit, and so on. It is fascinating how the origin of zero bought changed and now it is used as a prime digit in mathematics. Before learning about the modern zero, let’s learn about the origin of zero in India,   Origin of Zero in India The origin of zero in India came from a well-known astronomer and mathematician of his time, Aryabhatta. The well-known scientist used zero as a placeholder number. In the 5th century, Aryabhatta introduced zero in the decimal  number system  and hence, introduced it in mathematics. After Aryabhatta, Brahmagupta described rules for zero in the 7th century. The most evident proof of the origin of zero in mathematics is mentioned in the oldest manuscript of India kno...

RAMANUJAN'S INFINITE SEQUENCE OF SQUARE ROOT (NESTED RADICAL).

Image
         INFINITE SEQUENCE OF SQUARE ROOT        INFINITE SEQUENCE :                   An infinite sequence is a list or string of discrete objects, usually numbers, that can be paired off one-to-one with the set of positive integer s {1, 2, 3, ...}. Examples of infinite sequences are  N  = (0, 1, 2, 3, ...) and  S  = (1, 1/2, 1/4, 1/8, ..., 1/2  n  , ...).  INFINITE SEQUENCE OF SQUARE ROOT: Consider,                  y = x + n                (x +n)² = n² + x(x+2n)               (x + n) = √[ n² +x(x+2n)]               (x + 2n) = √[ n² +x(x+2n)(x+3n)]               ( x + 3n) = √[ n² +x(x+2n)(x+3n)(x+4n)]               ...       ...
