Have you ever thought about what happens if you write the number ‘1’ a thousand times in a row? It turns out, you get a very special kind of number. Let’s talk about it!
The unique property of 73939173 is its ability to remain prime even as we strip away its digits, one by one, from the right. Let’s explore this phenomenon.
Imagine taking the number sequence “4567890123” and writing it down nineteen times in a row. Once you’ve done that, you append the number “4567” to the end. This seemingly arbitrary activity results in a number that spans a whopping 197 digits. But, the real magic of this number isn’t just its length or formation – it’s the fact that it’s prime!
Belphegor’s Prime is 1000000000000066600000000000001. At first glance, this might just seem like a long number, but it holds an intriguing secret. Found by Harvey Dubner, this prime number has an uncanny design.
The origins of this fascinating number trace back to 1683 when the Swiss mathematician Jacob Bernoulli stumbled upon it. While Bernoulli wasn’t specifically searching for a new mathematical constant, he inadvertently discovered the first approximation of e during his studies on continuous compound interest. This makes the story of e particularly intriguing; it wasn’t the product of abstract mathematical thought, but rather a result of tangible financial studies.
Exciting news for everyone diving into the world of Machine Learning! I stumbled upon a fantastic resource that consolidates all the essential math needed for ML, and guess what? It’s free (download here).
In 2000, the Clay Mathematics Institute listed seven big math problems and offered a million dollars for each solution. These are called the Millennium Prize Problems. 23 years have passed, and we’re checking in to see how far we’ve come.
