Nikola Tesla was undoubtedly one of the greatest minds.But unfortunately while he was alive he didn't gained the popularity he deserved. It is believed that he had performed countless number of mysterious experiments along with science experiments. He was whole other mystery on his own.There are varieties of secrets and mysteries associated with him.

His strange obsession with the number “369” made people believe him to be superstitious. He used to take three complete rounds of a building he was about to enter. He only selected rooms whose number was divisible by the number three. He used eighteen napkins to clean his dishes . Some people also believed that he was suffering from OCD( obsessive compulsive disorder).  Almost all genius minds have a certain obsession.But he used to say “ if you only knew the magnificence of the number three (3), six (6),nine(9)  then you would have a key to universe ”.

But what made him consider the number “369” magnificent??. It is known that there are three subatomic particles; protons, neutrons, electrons; there are three state of time past, present, future. Nikola Tesla believed so much in the Power of number “369” that he wanted to convey it's significance to the whole world. Let's try to understand the mathematics behind this number. It is believed that  Maths is the language of the Universe. Universe communicates with us through the language of maths if you will closely examine the numbers.

Let us closely examine this: 

If we will add:.

1+1=2;

2+2=4

4+4=8

8+8=16;1+6=7

16+16=32;3+2=5

32+32=64; 6+4= 10;1+0=1

If we will continue this series we will find that there is no trace of numbers three, six, nine .

Now;

6+6=12; 1+2=3

12+12=24; 2+4=6

24+24=48; 4+8=12; 1+2=3

48+48=96; 9+6=15;1+5=6

 If we will further continue this pattern we will notice that nine never comes.

Now consider this one; 

9+9=18; 1+8=9

18+18=36;3+6=9

36+36=72; 7+2=9

72+72=144; 1+4+4= 9

144+144= 288; 2+8+8=18;1+8=9

So if we will continue this series only the number nine appears.

The angle around the point of geometrical shape circle is 360 degrees.If we add 3+6+0=9;

The sum of angle of geometrical shape triangle is 180 degrees . If we sum up it's digits 1+8+0=9 ;

Nikola Tesla used to emphasise that divine code is embedded in our number system. He used to say “ the day science begins to study non- physical phenomena, it will make more progress than it made in all the previous centuries of it's existence.”
