Today, a long overdue foray into the realm of VORTEX MATHEMATICS :)
00:00 Intro
04:16 The vortex
08:10 The maths of remainders and digital roots
13:25 Demystifying the vortex
16:30 A matter of base. The 8 fingered Tesla.
19:21 Explanation why the digital root is the remainder on division by 9
24:01 Tristan's challenge
24:44 The magic of modular multiplication maths
25:19 Intuition for multiplier - 1 petals
28:23 Thank You!
Coding competition:
My wish list for the modular times table diagram app:
-Being able to color line segments according to length.
-Indication of the "direction" of multiplication. 1x2 = 2 and so there should really be a little arrow from 1 to 2 not just a simple connection :)
-different loops in different colors.
Here is the prize, a copy of my and Marty's new book.

What I am talking about in this video is really just the tip of a bizarre mathematical iceberg that most mathematically minded people are completely unaware of. Have a look at this presentation by Marko Rodin on vortex math (beware serious nutty and at the same time truely beautifully presented numerology ahead :) A LOT more than is usually reported on in popular KZbin videos.
In turn this iceberg is just another tip of an even bigger iceberg of mainly wishful thinking. Have a look: sciencetosagemagazine.com/cat...

In school whenever I noticed patterns such as these divisibility tests, my teachers discouraged me from pursuing them because they themselves were not sure if they'd always hold and were concerned they'd lead me astray. Another example that I recall is my noticing that each power of two is equal to one more than the sum of the lesser powers of two. That's well-established and taken for granted in computer science, yet was unknown to my teachers and regarded with skepticism. I remember also my mom pleading with my teachers to stop counting my work wrong for my daring to use techniques I developed myself from having explored the mathematical foundations of the rote mechanisms they taught. I understand that the pressures on elementary school math teachers drive them to stick with safe techniques, but for them to feel threatened by a student privately moving beyond that is frankly an indictment of the whole system of education.

@Ryan Gardiner This is true in very rare cases like private schools or maybe in a few countries. This is not true for every where in the world. There's a lot that needs to be done still. But I see you're a music teacher. If you're teaching music at Elementary. Music is great for at the same time teaching mathematics, I'm a producer myself. Musical mathematical patterns are a lot more in line with the world and problem solving due to their reoccurrence in nature and the universe itself.

this is something I've not been exposed to before. I'm 68 so I'm a product of what I learned before around 1973. however, to use your vernacular, as soon as you started talking about the number nine I was saying to myself, all that really is is b - 1. I was a COBOL programmer for a few decades I'm familiar with base 8 and base 16. some of the other programmers I worked with used to call me a bit fiddler. in fact, I remember learning about using different bases way back in 1963 in summer school at my grade school. it was very confusing at first. but the bottom line for me even from the beginning of this video was that what it's really showing is just how fascinating the relationship with numbers is, rather than any kind of a key to the universe. but as you pointed out later, that the universe is based on mathematics. heck, even music is based on mathematics.

Looks like I unknowingly introduced this to myself and my wife and daughters with a little game we used to play while travelling. We would add up the numbers on license plates and see who came up with the "digital root" the quickest, even though we didn't know that was the term to use. We saw very quickly that any combination of numbers that add up to 9 could be eliminated so 572 would be 5 without going through the process of adding. Later, as 3 or 4 number plates lost its challenge, we included letters. The letters "I" and "R" could automatically be eliminated since they corresponded to the number 9 and 18 respectively. This expanded the challenge because you had to figure out the numbers corresponding to the letters. As you played the game this became more intuitive when you could eliminate combinations of letters that added up to 9 for elimination. Example GSP562 would be 1. One of my daughters got so good at it that within seconds she could get the digital root of signs with just letters such as names of towns or short sentences.

(Mid 1960's) He used a book called The Calculator's Cunning which used number theory to teach people how to perform complex math in their heads. I still have the book.

The main reason people don't teach these rules in high school is that they are never actually used for anything. We also don't teach how to compute products with a slide rule. (That said, I _did_ learn how to find products using log tables in high school, which I thought was bizarre.) Divisibility rules _are_ useful in primary school when learning to reduce fractions, and that's where I learned the rules for divisibility by 2, 3, and 5. Of course, if you think about it, these rules also give you the remainder if you divide by that number. Like, the divisibility rule for 5 says that if a number ends in a 0 or 5, then it is divisible by 5. I think most students realize pretty quickly that if a number ends in 1 or 6, it is one more than a multiple of 5, and if it ends in 2 or 7, it is two more, etc. This works for 3 in the same way. Although the divisibility rule itself is less obvious (that a number is divisible by 3 iff its digital root is 3, 6, or 9), the corollary still is. If 51 is a multiple of 3 (cause it's digital root is 6), then 52 must be one more than a multiple of 3, and 53 must be two more. That's basically all that's going on here. If you take a class on number theory, this basic idea comes up in more general form pretty quickly. But there are like fifty things I wish I had learned in high school math, and this barely even makes the list. There's just too much math to teach.

The digital root is fun with 11 as well. 10 is congruent to -1 mod 11 so you just add the even digits, subtract the odd digits of a base 10 number, then you get an easy analog for "11" digital roots.

Great explanation of the mathematics behind this. Would appreciate a video adding some physics into the story, e g. explaining the same thing starting with a base frequency (1) and observing its harmonics (doubling, i.e. mul. by powers of 2). Then thinking about resonant frequencies (like in the story where soldiers marching on a bridge in a resonant freq. amplifying the vibration destroy it). How do 3/6/9 fit into such a perspective? Would they help with more efficient vibration amplification using resonant frequencies than the other numbers. What if the base frequency is the frequency of the Earth (or make base its third, so Earth frequency is number 3)? No idea whether any of it would make sense, just curious to have an expert cover the topic...

When you find the frequency of the earth, see if it can be a tool for healing on a rapid scale. We are all from the earth, when we separate ourselves from the frequency we get sick. Reconnecting with the frequency heals, and some light frequencies have been used for the rapid healing process.

I personally was not taught these math tricks in the 1970"s in grade school. Deliberately. I am thankful for it. We learned to do problems the long way and then without paper. We learned to visualize number patterns like the 2 and 5 trick in a base 10 system. My classmates and I were faster than any calculator and always right. In 4th grade We wrote a 0x0 to 15x15 multilocation tables or division tables, including the table itself and filled it in in under 30 seconds. We at the time thought our teachers were mean but they were very correct. I rarely used a calculator until I got into long complex math and calculus. But my son was taught these tricks in the late 1990's. I tried to discourage them. He was am excellent student but had trouble visualizing complex problems and doing math in his head. I never let him use a calculator even when his teachers would. They are nice but have limited practical use. These tricks happen in a even numbered base system like base 10 (0-9). But all bases should have similar tricks in any repeating number system. They are not keys to the universe since math is am man made construct. Thank you for clarifying that. Those other similar videos are all just hype.

I the 1950's I was taught to check math problems by something the teacher called "casting out nines." I didnt know why it worked but was intrigued by it. 60 years later I stubble across the answer.

I was in grade school in the 60's in NY and was taught the same thing and they also called it "casting out nines". Later in life when we were using printing calculators and you had to "double tape" every bank deposit, if your two results were different and the difference was divisible by nine, you knew you had a transposition error.

Divisible by 9 errors in accounting are many times a transposing error ..eg writing 187 instead of 178 ..the difference is 9( 187 -178)..back in the days of adding up columns of numbers w a calculator .

Harmonising frequencies are just fractions or multiples of a key. All Harmonising notes that make a cord share a mathematical correlation to the key, fractions. That's the basics of it. Take the highest frequency note in the cord, and all the lower frequency harmonising notes that make that cord will have frequencies that equal fractions of the highest frequency note.

@Gustavo Neves I'm guessing you are perhaps stumped, so I'll present it another way. You say "there is a pattern in everything", but still, you don't realize the simple art of not allowing for a pattern to exist, nor the beauty of breaking the common rule that a pattern must somehow always exist. The origins of art is simply to appreciate, that which had a beginning with or without a preceding pattern, as well as an end, which likewise never required a preceding pattern. I hope that makes some sense, friend.

@Gustavo Neves "For some reason you seem to think that these things compete..." No. I simply disagreed with your first opinion that art comes from mathematics. That was entirely a projection on your part. It sounds like now you are admitting that mathematics actually comes from art when you say "mathematics is a form of art", but somehow you still wish to be right. I can't argue with your two competing views when one is correct.
Gustavo Neves

@Rick the Swift Just because you don't see a pattern, it does not mean it is not there. There is ALWAYS a pattern in everything. The question is if we can understand it already or not. Mathematics in itself is a form of art. The great minds in both areas were always people that thought out of the box. And always combining patterns in ways unexpected. For some reason you seem to think that these things compete...
Rick the Swift
Rick the Swift 8 ай бұрын
@Gustavo Neves Respectfully, I disagree with part of your comment. Math CAN be a basis for art, but doesn't have to be, and in fact art can easily stand alone, without any knowable form of math involved. I too, like the OP decided where I would focus my talents, between art and math, and likewise, I chose art. Art, is a basic foundation of humanity, and likely a basic foundation to many other creatures as well. Let's not bring Darwinism into the equation just yet, but suppose a group of creatures who were quite ape-like in many aspects, had a special ape within the group- one who just seemed a little brighter than the rest from an early age, and even showing considerably more learning ability than even the wisest of the elder apes. And suppose too that one day the apes come back from hunting/gathering to find a rather large splat of condor poop just above their heads on the face of a large rock they slept under. All of the apes see the bright splat of poop and some are wondering what caused it, while others already recognize it as being poop from a large bird. Now, imagine our special ape walking up to the poop splat, pointing at it, the pointing at one of the other apes, immediately recognizing a resemblance. Other apes in the group can't quite make the correlation, so what does our special ape do? He picks up a stick, and dips into some mud or wet ashes, and attempts to replicate on the rock what he sees in the bird poop, only he replicates it with the intent on highlighting certain features which will help others realize he is painting a portrait of an apes face. Of course as someone who understands math, you could argue the special ape was calculating angles and mathematical patterns, but I as an artist I understand the special ape merely simply saw one thing, and had the courage to imagine it was something else other than what he knew the material to actually be. To fake something, or fool someone. I could also argue that the most important part of what the special ape was doing was completely void of math, and indeed it only had to do with the desire to be a part of something bigger, to live in the moment of true inspiration, or to lavish in one's own egotistical self. I think that too often people who latch onto math as their " key to the universe" often miss out on what true art and beauty really means. Yes, much of our music and visual art is filled with mathematical concepts, but they don't always lie at the heart- they are at times simply tools to help the artist express deep emotions and ideas. Yet some of the most beautiful music is often complete silence, and with no calculable time patterns. Just as often the most beautiful and artful part of a motion picture, or a theatrical production may be complete blackness, where any concept of math would be completely out of place, and merely a projection of someone who willfully desires for it to be there. In the end, it may in fact turn out that art is at the very foundation of mathematics as we discover that many mathematical formulas turn out to be mere illusions created by clever con-artists who meant to mislead or persuade others.

I first ran into this bit of math, and realized that it wasn't limited to the number nine whenever in electronics and computer science classes I had to deal with numbers in base systems other than 10. it appeared with the last numeral of the sequence; 9 in base 10, F in base 16, 7 in base 8, 255 in base 256 and so on, I realized that it wasn't that 9 was so magical, than that it was an effect of whatever integer numbering system was being used, the last numeral in that system held prevalence in exactly the same way. That being said, 3 being a prime, and 6 being the product of the first two primes does present some interesting components, regardless of the numbering system. I have found in electronics, pi and e have more prevalence, though usually expressed as fractions or products of such, especially in AC theory. Kinda hard to integrate either into integer number systems however, not being integral
