The Number of the Beast

By Anupum Pant

666 is probably one of the most infamous numbers and is known by many as the number of the beast. That is because the Bible, as translated in English, mentions 666 as the number of the beast. Revelation 13:18 says this…

Let the one who has understanding calculate the number of the beast, for it is the number of a man, and his number is 666.

However, it is very interesting to note that, since the Bible wasn’t written originally in English, the number 666 wasn’t actually there in the original form. In the original Greek manuscript, a language (like Hebrew) which uses letters for numbers, the number is written as 3 letters. I did not know this before. That means, all of the Greek and Hebrew text can also be read as numbers!

This is called isosephy – Meaning a practice of writing text where a text can be a number too. Normally the number values associated with each letter of a word are added to form a number.

So, the letters of my name (A, N, U, P, U, M), in order, would be the numbers: 1, 50, 300, 70, 300, 40. Total: 761 – Which is not very close to 666, I’m not a beast. What about yours? You can look at the table below and calculate.

Nero Caesar written in Hebrew can be converted to numbers and the total is 666. A way of saying, by the author, that Nero Caesar is the root of all evil. At the same time, the author doesn’t end up in trouble for writing this.

Also, all the 36 numbers on a Monte Carlo roulette wheel add up to 666. Watch more in the video below.

Mastering The Best Useless Skill – Reading Text in Binary

By Anupum Pant

The next time you see a series of 0s and 1s, you will no longer need to take it to a computer and feed it in to read it. Of course you might never have to read a text in binary, and that is the reason this might be the most useless skill you could master right away. I’m doing it anyway.

Tom Scott from YouTube  recently posted a video on YouTube where he teaches you how to read text written in binary. It’s fairly easy. The only thing you need to practice, if you don’t already know it, is the number that is associated with each alphabet (Like it’s 1 for A and 2 for B and so on).

Wilson Primes

By Anupum Pant

Thanks to the guys at Numberphile for introducing me to Wilson primes. Although the piece of information that describes Wilson primes itself has more or less no practical use, I still think it’s a good thing to know.

The first thing you need to know is that all prime numbers follow this rule – If you take a prime number P and put it in the following equation you get a number that is perfectly divisible by the prime number P.

The equation: (P − 1)! + 1 = Q

Note: ! is a sign used for factorial. That means P! is equal to the product of all natural numbers smaller or equal to P. So, for example, 3! = 3 X 2 X 1

This rule is valid for all prime numbers and no composite numbers follow it. So, for instance, if you take a composite number for P, the number you get after you put it in the above equation is never divisible by the number itself. This is called the Wilson’s theorem.

Wilson primes (P) are a few special numbers which can divide Q in the equation above two times. So, for example, since 5 is a Wilson prime, you get 25 if you put it in the equation above. And 25 can be divided perfectly by 5 once, and the result (quotient 5) can be divided again by 5 to get a whole number.

Now, for Wilson primes here’s the deal – 5, 13 and 563 are Wilson Primes. And a very interesting thing to note here is that, in spite of all the computing technology we have in the world, these are the only three Wilson primes we know yet.

Mathematicians are pretty certain that there are several other Wilson primes waiting to get discovered, probably infinitely many. But one thing is for sure, below the number 20,000,000,000,000 5. 13 and 563 are the only three which exist.
