  In this post, I am going to explain 4*4 Ramanujan Magic Square. And also I am going to explain how to create our own 4*4 Magic Square .   Now let us write Ramanujan Magic Square in the following steps . Step 1: Write the Date of birth of Sir. Srinivasa Ramanujan i.e.,  22 December 1887 . Step 2: Draw a 4*4 Table . Step 3: Before going to tell the trick to solve 4*4 Magic Square, for your understanding just see this image . Step 4: Understand  this table, because this is important and this table is the trick to solving any Magic Square not only for Ramanujan Magic Square. So, please understand this table carefully . Step 5: If you solve this table for the data, you will get like this : Conclusion:   Now I'll show the combinations of numbers in which you will get the same result . If you add any of these four rows, you will get the result 139 . If you add any of these four columns, you will get the result 139 . If you add these 4 numbers in boxes, you will ...

ANTIMATTER

In physics, we define antimatter as the  matter which is composed of the antiparticles of the matter. Anti-matter can be formed only for a few nanoseconds by colliding or hitting two particles.    A particle and its anti-particle (for example, proton and antiproton) have the same mass, but opposite electric charge and other differences in quantum numbers. For example, a proton has a positive charge while an antiproton has a negative charge. Antimatter particles bind with each other to form antimatter, just as particles bind to form normal matter. For example, a positron (the antiparticle of the electron) and an antiproton (the antiparticle of the proton) can form an antihydrogen atom. Easily we can understand that in matter electron revolves around the proton. But in Anti-matter, positron revolves around anti-proton. Scientists claim that anti-matter is the costliest material that they make.  It costs approxima...

Kaprekar's Constant:'495 and 6174'

In this post, I am going to prove Kaprekar's Constant. Now let us prove this by taking some examples . 3-Digit Number Rule: Example 1: I'm taking a three-digit number '658'. You can assume any 3-digit number. Condition : You should not assume the same numbers as 999,111,222, etc. Because if you take in the form a Descending number - Ascending number, you will get 111-111=000 . But you can assume 3-digit numbers like this: 665, 991,344 . For this number, the Descending number is '865' and the Ascending number is '568'. Subtract the Ascending number from Descending number . Next, take the number 297. For this number, the Descending number is '972' and the Ascending number is '279'. Subtract the Ascending number from Descending number . Next, take the number 693. For this number, the Descending number is '963' and the Ascending number is '369'. Subtract the Ascending number from Descending number. Next, take the number 594....
