Fascinating. And dangerous.
If you see a pattern and you search a explanation for it, you can get wrapped up in the hunt and end up investing a lot of time into a wild goose chase.
Our math profs warned us to do this, because if you zoom out wide enough, there is a pattern in every noise. As a undergrad, i got obsessed with the idea of creating a meaningful divide by zero operation.
The result, if i remember correctly, was a "fractal" cave, interconnected, the walls defined by aggregated infinitys reseeded by the "echos" of all previous caves until the next "digit" of the original seed number is reached. What a useless operation, one might think- but i got obsessed with it, because it generated sequences.
1/0 = |1|0/0=1|2|3|5
Some of the results started to look like the fibonacci-sequence(its basically a algorithm mapped to infinity echoing back and forth along the cave-walls after all) and i lost a semester chasing this numeric day dream. :(
Shame on me, i woke up when my math prof zoomed out over some random pattern revealing "patterns". The Truth is, we humans want to see patterns. Desperately. So desperatly it can eat lives.
Still a fascinating read, can fully recommend. But wake up if you what you find eats you.
PS: To double my shame, i did never publish this. So if you venture down the rabbit sinkhole, put a warning sign up.
- drvdevd 10y agoI haven't read the article yet but your comment just reminded me of one of my all-time favorite movies: Pi (1998). Please watch it if you haven't! [edit] took a look and this is quite beautiful. Of course the search for a pattern in the primes could easily take over your mind...
- leeoniya 10y agoi liked Pi a lot, but the thing that nagged me is how any name that could ever hope to be spoken be represented by 216 digits :/

- hvidgaard 10y agoFor that to happen, we need the number to be a "Normal number" (https://en.wikipedia.org/wiki/Normal_number https://en.wikipedia.org/wiki/Normal_number). We just don't know if Pi is normal or not - it's expected to be.
- leeoniya 10y agoi have no idea how this follows from my comment. all i'm saying is that any spoken name which must be represented by 216 digits would be an order of magnitude more ridiculous than Rindfleischetikettierungsueberwachungsaufgabenuebertragungsgesetz: http://www.bbc.com/news/world-europe-22762040 http://www.bbc.com/news/world-europe-22762040
- hvidgaard 10y agoMy mind was in a completely different world when I wrote that reply. You're right, it doesn't have much to do with your comment.
- jerf 10y agoIn high school, I created the number b, whose absolute value is zero. I discovered the following additional interesting facts about it: ∅

- dnautics 10y agoYou didn't try hard enough. Dual numbers are extremely useful. You can use them to calculate derivatives easily. I'm thinking about making a video demonstrating how these numbers can accelerate machine learning.
- myowncrapulence 10y agoI mean, they could only be "worthless" to our current application of said patterns. Maybe in the future, those patterns will find use in quantum computing or cryptography or other avenues. For the mathematician a pattern will be useless but applied in a separate field can yield meaningful results. That is not to say, it is worth anyone's time to map out these patterns, but simply that they may become useful in the future applied in ways not yet thought.
- vlasev 10y agoHow exactly do you generate those "fractal" caves, "echoes" and sequences?
- robertelder 10y agoBut there is a pattern. It's just a simple sum over all non-trivial zeros of the Riemann Zeta function[1]. It will pop right out at you if you take a look at the proof for the Riemann hypothesis (an exercise left to the reader). Also, speaking of Riemann, division by zero is also spoken for[2] [1] https://en.wikipedia.org/wiki/Explicit_formulae_(L-function) https://en.wikipedia.org/wiki/Explicit_formulae_(L-function) [2] https://en.wikipedia.org/wiki/Riemann_sphere https://en.wikipedia.org/wiki/Riemann_sphere
- zardo 10y agoThere's also the wheel approach to dividing by zero. Which handles 0/0 as well. https://en.m.wikipedia.org/wiki/Wheel_theory https://en.m.wikipedia.org/wiki/Wheel_theory
- mathattack 10y agoWhat you said applies quite a bit to Financial Mathematics. The stakes are high and people look for patterns in the noise. They see patterns because if you look in 1000 random sequences, you'll find 50 statistically significant patterns. And they never publish their mistakes either. :-)
- banku_brougham 10y agoI appreciate what you are saying, but noise looks like noise. Here's an example of a useful pattern: the blank line extending to the right from zero, corresponding to the numbers {n^2 | n in 1,2,3,...} and below it {n^2-1 | n in 1,2,3,...}. Such a great example of a visualization helping to illuminate the abstract truths in numbers. Its obvious to most people that {n^2} contains no primes. Is it obvious that {n^2-1} doesnt't either? (except where n=2)
- pwdisswordfish 10y agon² - 1 = (n - 1)(n + 1)
- banku_brougham 10y agoprecisely. maybe its a trivial example, but if no mathematician had discovered the factorization of n^2 - 1, this visualization device would have been a helpful clue.
