Nikola Tesla is perhaps the most enigmatic inventor that has ever existed, with his great intellect he was able to decipher secrets of natural forces that allowed him to create extraordinary inventions that even border on mysticism, such as his so-called ‘Death Ray’ that never went off. verified that it existed. But electromagnetic energy was not the only one that Tesla studied to death, numbers were also an important part of the very configuration of reality for him.

Many attribute the phrase «If you knew the magnificence of the numbers 3, 6 and 9, you would have the key to the Universe», a simple statement but one that holds great mysteries in itself. And it is that perhaps Tesla better understood how mathematics is the very representation of reality, since surprising properties have been found in these three numbers, so much so that they have been called the ‘creation code’, the one that embeds reality and become something tangible.

Nikola himself lived an organizational form attached to the triad of numbers, always carrying out his activities in orders and series of three. Perhaps out of mere obsession or because he really understood the power of numbers, the truth is that mathematicians have discovered quasi-magical properties that are hidden behind the numbers 3, 6 and 9.

## The omnipresence of 9

In particular, 9 seems to be omnipresent as if existence itself had this number embedded in its code. The circle is the best place to start breaking down the magic; every circle regardless of its size is measured in the same number of degrees. And what are those degrees? Well, the well-known 360º that from the outset the first thing that jumps out is that it includes the numbers 3 and 6. But in addition to that it keeps more secrets such as that it is divisible by 2, 3, 4, 5, 6, 8, 9, 10, 12… and that it is close to 365 days of the current calendar, although not all ancient calendars were measured under these days, many of them are close to 360 days, this being a kind of cosmic circle.

From here the coincidences that seem rather causal begin to emerge in gushes. The calendar is subdivided into 12 months with approximately 30 days each and if you are an astronomy lover, you will know that the sky is divided into 12 zodiacal constellations that occupy approximately 30º each, approximately one month and what it gives us in full 360º of the ecliptic.

But this is just the beginning, because no matter how much we reduce time units, the sum of the digits will always be 9:

A day has 1,440 minutes that add up to 9 (1+4+4=9). In turn, a day has 86,400 that added their digits give 9 (8+6+4=18; 1+8=9). In turn, a week has 10,800 minutes where 9 appears again and even the year that has 525,600 seconds gives us 9 as a result in the addition of all its digits.

On the other hand, if we go to the field of numbers, we can see that if a 9 is added to any number, the sum of the digits of the resulting number will always be equal to the initial number. For example:

1+9=10 (1+0=1); 2+9=11 (1+1=2); 3+9=12 (1+2=3) and so on.

And with the sum of digits you can also reach other wonders; If all the numbers from 1 to 9 are added and we carry out the same process of adding digits, the result will be the same: 9.

1+2+3+4+5+6+7+8+9=45 (4+5=9).

Multiples of 9 are also involved in this wonder; any factor multiplied by 9 will give us as a product a figure whose sum of figures will be equal to 9.

9×1=9; 9×2=18 (1+8=9); 9×3=27 (2+7=9); 9×4=36(3+6=9)….

But if we go back to the circle and its 360º we will also get many more revelations. Suppose you already noticed that the sum of the digits of 360º equals 9, but what about other angles? Half of 360º is 180º which added together gives us 9 (1+8+0=9). In turn, if we divide the circle into four equal parts we obtain 90º and of course, here 9 is already evident, but the same happens with an eighth of a circle that gives us 45º (4+5=9).

It seems that the 9 is omnipresent both in the totality and in the emptiness of reality itself, a fact that we may not have been able to understand but that cannot be denied that it exists.
