Stop asking me for my phone number you bitch ass websites. The only 'two factor' things that interest me are the beautiful prime numbers 💙

That is a nice emergent pattern!

I wanna juggle with some thoughts/interpretations about dynamical aspects of the distribution of primes.

Let's see where these ideas will lead... //perhaps nowhere, but I'm #havingFunInTheMetascape!

I recently learned there's a company that makes 13-sided dice, and in like a microsecond my goblin brain decided I absolutely had to have one or I'll die.

Behold, the baker's dodecahedron

They come in 12 different colors, and they're only 3 bucks a pop, so I might splurge and get one of each. I am a simple man, and I am excited by simple things. The number 13 means a lot to me for a variety of reasons, so this sparks more joy than it rightfully should. I love it.

I don't even play tabletop games, I just think dice are neat! I'm gonna start collecting them.

The contradiction: Mathematics note- 1 (Essay)

I wanted to go on to study mathematics, but I couldn't fulfill that dream. But I still like mathematics, and I'm going to list some episodes that come to mind.

There is a proof method called the contradiction. Write about this powerful and elegant way. When there are several possibilities (A, B, C, . . . ), the conclusion is drawn by showing that only A is true. More directly, when there are two cases, A and non-A, If the possibility of non-A is denied,it derives the contradiction of being non-A and proves that only A is true.

Let's apply the contradiction to the theorem "there are infinitely many prime numbers". If this proposition is A, non-A is "there are only a finite number of prime numbers." I will try to deny this proposition. (A prime number is a natural number that has no divisors other than 1 and itself.)

If there are a finite number of primes, let the largest prime be called P. Then multiply it by a smaller prime number and add 1. (By the way, 1 is not a prime number)

1 * 2 * 3 * 5 * 7 * ... * P + 1 (@)

As you can see from the equation, this number@ is not divisible by any prime number of 1, 2, 3, 5, . ,P. You can call it a prime number. And this number is definitely greater than P. Therefore, it is negated that P is the largest prime number, and "non-A" does not hold. Therefore, as a conclusion of this paradox, "A" holds. In other words, there are an infinite number of prime numbers.

The contradiction is a methodology developed in Greek mathematics, and logically speaking, it is based on the "rule of exclusion the middle" and appears in all aspects of mathematical proofs. However, it seems that the "rule of exclusion of the middle" does not necessarily hold true in Eastern philosophies such as the teachings of Buddha or Lao Tzu. This powerful tool of mathematics will also need a more radical overhaul.

Just any ol prime number? 2, 3, 5, 7, 11, 13, 17.....

pick one.

What is the largest two-digit prime number?

The largest two-digit prime number is 97. It is also the only prime number between 90 and 100. A prime number can only be divided by 1 and itself.

The largest known prime number is much larger than 97. The largest known prime number to date is 2 to the power of 82,589,933 minus 1. This number has over 24 million digits and was discovered in December 2018.

Despite being relatively small compared to the largest known prime number, 97 is still an impressive number. It is a crucial component of number theory and cryptography, and it serves as a reminder of the beauty and complexity of mathematics.

Hey um I'm concerned...

Something something about the cycle repeating. 👀

Well, now that is a very small drop in a very, very large bucket of drugs.
