Zero was never banned from Western thought. The Greeks opted for the use of 27 greek letters to represent numbers from 1 to 999 and they already used a small circle to indicate that a 3-digit column was empty. The Romans used the minus sign, normally used to represent negative numbers (debts essentially) without any figures to mean zero.

I once heard that the Egyptian pyramids were built with the aid of measuring instruments that were simple in design, like two sticks connected by a piece of rope or string. The circles and lines they would get from them would be like compasses, and the geometry of the interaction of those shapes would go towards the design of their architecture (would need to verify, this is something from way back in school). If there's info on it, it would be neat to know what type of geometry and math the Mesopotamians were using to do things like build their ziggurats.

In India, Zero is called Shunya. Indians were ofcourse familiar with it as it is mentioned even in Vedas, and it became one of the most important thing in Indian philosophies, from Vendanta to Mahayana Buddhism. Brahman is said to be ultimate reality who is full in itself, but it is also shunya at the same time. There is verse in Isha Upanishad "That is perfect, this is perfect, what is taken from perfect is perfect and what remains after taking it out is also perfect" It was Aryabhatta who invented symbol for 0 and other numbers, which were taken by Arabic traders and are Known as Arabic numerals instead in the west. (Aryabhatta was also the person who first said that earth rotates on its axis and he calculated accurate circumference of the earth, he have done some other cool stuffs also) Brahmagupta introduced concept of negative numbers. 0 is necessarily not nothing but where both opposite qualities combine. Like if there is elevation of ground, that will be positive and if there there is depression, it is negative, the place where the ground neutralises is the 0. That is how concept of negative numbers took place. Brahmagupta was also the first person who proved that 0 divided by 0 is infinity. He also have done some other cool stuff.

You are right. For example. Preface. Positional natural a-ary d-digit number systems can represent some kind of polytopes. For example: binary d-digit number system is a d-vertex simplex.(vertices is a numbers whith digital root=1, edges is a numbers with digital root=2 and so on) 2^n-ary d-digit number system is a n*d-vertex simplex with 2^(n*d) faces (for simplexes externity is considered to be face). 3^n-ary d-digit number system is a d-cuban3. If 1-chain (2 vertices + 1 edge) shift 1 times we receive 2-cuban3 with 3^2=9 faces, i.e. square. 5^n-ary d-digit number system is a d-cuban5. If 2-chain shift 2 times we receive 2-cuban5 with 5^2=25 faces, i.e. 4 square joined together. (2*3=6)^n-ary d-digit number system is a d-mebius6. if 3-ring (1D triangle) shift (2-1)*3 times and "press" 1 chain into 1 vertex we recieve 2-mebius6 with 6^2=36 faces = (3-2)*3 square + 2*3 triangles + 2*3*3 edges + (3-1)*(3+1)+1 vertices , because in 1D-rings shapeless Zero (wich in simplex is a Externity) is "pressed" into 1 vertex and can't generate new shapes . 7^n-ary d-digit number system is a d-cuban7. If 3-chain shift 3 times we recieve 2-cuban7 with 7^2=49 faces, i.e. 9 square joined together. (2*5=10)^n-ary d-digit number system is a d-mebius10. if 5-ring (1D pentagon) shift (2-1)*5 times and "press" 1 chain into 1 vertex we recieve 2-mebius10 with 10^2=100 faces = (5-2)*5 square + 2*5 triangles + 2*5*5 edges + (5-1)*(5+1)+1 vertices . 11^n-ary d-digit number system is a d-cuban11. If 5-chain shift 5 times we recieve 2-cuban11 with 11^2=121 faces, i.e. 25 square joined together. (2*6=12)^n-ary d-digit number system is a d-mebius12.if 6-ring (1D hexagon) shift (2-1)*6 times and "press" 1 chain into 1 vertex we recieve 2-mebius12 with 12^2=144 faces = (6-2)*6 square + 2*6 triangles + 2*6*6 edges + (6-1)*(6+1)+1 vertices . 13^n-ary d-digit number system is a d-cuban13. If 6-chain shift 6 times we recieve 2-cuban13 with 13^2=169 faces, i.e. 36 square joined together. (2*7=14)^n-ary d-digit number system is a d-mebius14.if 7-ring (1D 7-gon) shift (2-1)*7 times and "press" 1 chain into 1 vertex we recieve 2-mebius14 with 14^2=196 faces = (7-2)*7 square + 2*7 triangles + 2*7*7 edges + (7-1)*(7+1)+1 vertices . (3*5=15)^n-ary d-digit number system is a d-mebius15.if 5-ring (1D pentagon) shift (3-1)*5 times and "press" 1 chain into 1 vertex we recieve 2-mebius15 with 15^2=225 faces = 100 faces of 2-mebius10 + 125 faces of 3-cuban5. And so on. So amount of faces of above type a - ary d-digit polytopes =a^d. Conclusion. For me as a programer, it's curious to know that difference in faces between consequent such polytopes is hexagonal numbers. So all natural numbers of all possible positional natural a-ary d-digit number systems exists with shape, realy: "No distinction between numbers and shape. Numbers could not exist without shape."

Back in the C64 days, the simplest way of dividing in assembler was to repeatedly subtract the divisor until it was less than the numerator. The number of subtractions was the answer and the remaining numerator was the remainder. If the divisor was zero, you'd end up in a never-ending loop as the numerator never decreased. Not sure if this was actually "infinity" since infinity is where parallel lines meet and recurring results converge but zero would actually never converge like that. I think.

I liked this video very much mainly for its open approach. But I have explained in my book that zero was probably discovered around 200 BCE. I do not think it had to be invented; because it was all along there, but it just did not occur to any till that day. The earliest reference to zero is found in the book called "Chanda Sastra" 4.32. It is created by Sage Pingalacharya around 200 BCE. The reference in that goes like this in Sanskrit. “Gaayathre shadsankhyaamardhe apaneethe dvayanke avasishtasthrayastheshu roopamapaneeya dvayankaadha: soonyam sthaapyam” Meaning: In gayatri chandas, one pada has six letters. When this number is made half, it becomes three. Remove one from three and make it half to get one. Remove one from it, thus gets the 'Soonya' (zero). Clear evidence for the existence of definite rules for calculations using zero appears many years later in the year in 1029 CE, in 'Siddhantha Sekhara' authored by Sripati, though it might have been in existence earlier. It says “Vikaaramaayaanthi dhanarunakhaani na soonya samyoga viyogathasthu soonyaaddhi suddham swamrunam kshayam swam vadhaadinaa kham khaharam vibhakthaa”. Meaning: Nothing happens (to the number) when a positive or negative number is added with zero. When +ve and -ve numbers are subtracted from zero, the +ve number becomes negative and -ve number becomes +ve. When multiplied with zero, the values of both +ve and -ve numbers become zero, when divided by zero, it becomes infinity ('khahara'). The place value of numbers seems to have been known around 650-700 CE. “Yathaa ekarekhaa sathasthaane satham dasasthane dasaiam chaikasthaane yathaa cha ekathvepi sthree mathaa cha uchyathe duhithaa svasaa cha ithi” (Sankaracharya, in 'Vyasa Bhashaya' to 'Yoga Sutra' - 650 CE). Meaning: In the unit place the digit has the same value, in 10th place, 10 times the value and in 100th place 100 times the value, given. Also “Yathaachaikaapi rekha sthaananyathvena nivisamaanaika dasa satha sahasraadi sabda prathyaya bhedhamanubhavathi” ('Sankaracharya', 'Vedanta Sutra Bhashaya II.2.17 - CE 700) Meaning: One and the same numerical sign when occupying different places is conceived as measuring 1, 10, 100, 1000 etc. May refer the book "The Hidden Messages in Indian Scriptures" (Chapter 13) ASIN: B07XL58DPH.

When you posed the Zeno's paradox problem, I paused it to try & work it out. I immediately realised that they would get closer together at an infinitely shrinking rate. I decided it would be infinitely close to 2, so my answer was 1.9 recurring. This, I think, solves the problem mathematically but is actually physically impossible as you can't measure a recurring distance accurately - you can always add another digit to improve accuracy. This ties in with a debate I had last week in the comments of another video where I argued that 0.9 recurring is not a real number as it can't be accurately measured - if you tried, you'd be measuring smaller & smaller distances forever as you added 9's. This principle applies to all recurring numbers & I don't think any of them are real numbers. They can't be called imaginary numbers, as they're not on the imaginary number line (with numbers that contain i. [Sorry, can't make it do the i in italics.]) They're on the real number line but still aren't real numbers, in my opinion, they're akin to pi. They should be called something like theoretical, hypothetical or conceptual numbers.

[@user_375a82]

Yes, I agree with you. And Pi could not be an exact number because you could not get an exact number of squares into a circle to form it's "area" by counting squares - remember squares form the unit of area. The old "squaring the circle" problem. A circle cannot have an exact area. And what you say about 1.9 recurring is spot-on - you've seen the glaring philosophical error in mathematics versus reality. Parmenides and Xeno knew this very well, Plato fudged round it setting us all on a terrible philosophical MISTAKE lasting until today and more. See my comment earlier, if you're interested.

Real numbers are defined as limits of sets. 1.999 recurring is exactly equal to 2. In fact that's how 2 is defined in real numbers. 2 is the max limit of the set {1,1.9,1.99,1.999 ...} . It can be limit of any other set so not that set specifically..As far as real numbers are concerned. 1.9999 recurring is just a different way to write 2. Though you are correct in a sense that all recurring numbers of type 1.999999... are akin to pi. The normal numbers you think about are rational numbers. "They should be called something like theoretical, hypothetical or conceptual numbers." They are already called something different they are called real numbers.

As zero was independently created/discovered by the maya with no relation to the other systems, I think it is a necessary abstraction. Much like how the empty set confuses a lot in set mathematics, you have to have a place that can be either empty or identifying to perform mathematics past most basic addition. That being only that which a positive result can occur. If you run out, that is all you need to know most of the time.

From today's perspective, looking at the elegance of the integer line: ... -3, -2, -1, ?, 1, 2, 3... The foundations, the potential for discovering negative numbers and 0 must be very old. Perhaps they were and had to be proposed several times, until the first societies were ready to adopt them. The integer line also introduces a symmetry between counting up and counting down, the latter no longer stopping at "nothing", at 0. However, integers are still a huge abstraction, distant from everyday experience.

Loved this one. Great job. One thing, though, while you were seeking the ultimate dramatic example @ 13:08, 1's and 0's are representation of "On" and "Off" or "Yes" and "No" for electricity to travel down one pathway or another in a transistor. This is a physical property of the transistor. If Zero didn't exist this property would still exist and electricity would still travel, when signaled, down one pathway or another, it would just be represented in some other symbolic language than a 1 or Zero. If you drop a rock, even with out Zero, when it hit the ground it would reach Zero velocity. Alan Turing's Machine was completely mechanical in nature, though it ran on electricity, it had no circuit boards using 1's and 0's. My long way around to the point is a computer could still exist without Zero. Other than that LOVE your stuff, keep it up.

We should INVENT a digit that is -1. Then we would not need to put a negative sign in front of numbers. Humans probably would not use it, but maybe it would have value in computers. Consider a base three system with three digits: x, 0 and 1 -- where x has the value of -1 if you did not guess. In this version of a base 3 system one counts forward from zero like this: 0, 1, 1x, 10, 11, 1xx, 1x0, 1x1 etc. And counts backwards from zero like this: 0, x, x1, x0, xx, x11, x10, x1x etc. 1x1 is 7 base 10 and x1x is -7 base 10.

You can argue from an analytic (as in real analysis, or the extension of rigorous calculus) perspective that zeno's paradox resolves to 2m without using 0. For any epsilon that is positive, enough terms can be added to get more than that distance from 2. Simply note that for 2-epsilon, you can continuously divide the distance between 1 and 2 by 2 until you pass the point. The whole point of analysis is seeing what happens when stuff gets small (very generally). You can still do that if you have no 0. Also, the fact that Binary uses 0 and 1 is more of just a notational thing. It's the concept of there being nothing (as in, a transistor is off), but it doesn't mean it has to be 0. You can just as easily use a and b or 1 and triangle.

11:00 Weren't negative numbers taboo in Europe for many mathematicians - even in the 13th and 14th Centuries, and possibly well beyond. From memory it was a real issue when they were looking for a general solution to cubic equations. This is well covered in the Welch Labs series on Complex Numbers, Veritasium has covered it, and Mathologer too. But the whole story might be worth re-telling here :-)

[@rmsgrey]

The problem with solving cubics is not the use of negative numbers but the fact that, if you look closely, somewhere in the middle of the solution you take square roots of a negative number. If you pretend that it makes sense to do that, imagining that there's some sort of number that squares to become a negative number, it all cancels out in the end, and you get a real number out as a solution, but you do have that pair of imaginary numbers in the middle...

[@guest_informant]

@@rmsgrey That is one problem with cubics and negative numbers, IIRC there are others.

[@altrag]

No, they weren't taboo by the time they were looking at cubic equations. The idea of negatives (particularly account balances) had been around a while by then (though negatives did have their own fraught history earlier on due to that "what does a negative area mean" connection with geometry that earlier mathematicians still insisted on, inherited from the Greeks). It was the square root of negative numbers (ie: imaginary numbers) that were the problem child during the time of solving cubics.

[@guest_informant]

​@@altrag From a Quanta article, for instance: "In the 16th century, algebraic equations were still expressed rhetorically - in words, not symbols - and all coefficients had to be nonnegative, since mathematicians did not recognize negative numbers as legitimate." My understanding was that the depressed cubics "had" to be expressed with positive values only. Within some solutions complex numbers appear (I think this was mentioned in the Veritasium video) but there were other objections to negative numbers _per se_ Regardless, negative numbers were a source of controversy for centuries eg web.stanford.edu/class/me161/documents/HistoryOfNegativeNumbers.pdf

[@rmsgrey]

@@guest_informant Considering you can flip the sign of any term simply by moving it to the other side of an equation, requiring all the co-efficients of a polynomial to be non-negative has no more of a limiting effect on mathematics than requiring them all to be on the left hand side. I haven't looked into it lately, but it wouldn't surprise me if you couldn't still find people arguing, in all seriousness, that negative numbers are not proper numbers, but merely mathematical fictions.

'IF' my latest TOE idea is really true, (and I fully acknowledge the 'if' at this time, my gravity test has to be done which will help prove or disprove the TOE idea), that the pulsating, swirling 'gem' photon is the energy unit of this universe that makes up everything in existence in this universe, and what is called 'gravity' is a part of what is currently recognized as the 'em' photon, the 'gravity' modality acting 90 degrees from the 'em' modalities, which act 90 degrees to each other, then the oscillation of these 3 interacting modalities of the energy unit would be as follows: Gravity: Maximum in one direction, Neutral, Maximum in the other direction; Electrical: Maximum in one direction, Neutral, Maximum in the other direction; Magnetic: Maximum in one direction, Neutral, Maximum in the other direction. Then: 1 singular energy unit, with 3 different modalities, with 6 maximum most reactive positions, with 9 total basic reactive positions (neutrals included). Hence 1, 3, 6, 9 being very prominent numbers in this universe and why mathematics even works in this universe. (And possibly '0', zero, as possibly neutrals are against other neutrals, even if only briefly, for no flow of energy, hence the number system that we currently have. This would also be the maximum potential energy point or as some might call it, the 'zero point energy point'.). And also how possibly mathematical constants exist in this universe as well. * Note also: Nobody as of yet has been able to show me how numbers and mathematical constants can exist and do what they do in this universe from the Standard Model of Particle Physics (SMPP). While the SMPP has it's place, I believe we need to move beyond the SMPP to get closer to real reality.

[@charlesbrightman4237]

@@xyz.ijk. (copy and paste from my files) Revised TOE: 3/25/2017a. My Current TOE: THE SETUP: 1. Modern science currently recognizes four forces of nature: The strong nuclear force, the weak nuclear force, gravity, and electromagnetism. 2. In school we are taught that with magnetism, opposite polarities attract and like polarities repel. But inside the arc of a large horseshoe magnet it's the other way around, like polarities attract and opposite polarities repel. (I have proved this to myself with magnets and anybody with a large horseshoe magnet and two smaller bar magnets can easily prove this to yourself too. It occurs at the outer end of the inner arc of the horseshoe magnet.). 3. Charged particles have an associated magnetic field with them. 4. Protons and electrons are charged particles and have their associated magnetic fields with them. 5. Photons also have both an electric and a magnetic component to them. FOUR FORCES OF NATURE DOWN INTO TWO: 6. When an electron is in close proximity to the nucleus, it would basically generate a 360 degree spherical magnetic field. 7. Like charged protons would stick together inside of this magnetic field, while simultaneously repelling opposite charged electrons inside this magnetic field, while simultaneously attracting the opposite charged electrons across the inner portion of the electron's moving magnetic field. 8. There are probably no such thing as "gluons" in actual reality. 9. The strong nuclear force and the weak nuclear force are probably derivatives of the electro-magnetic field interactions between electrons and protons. 10. The nucleus is probably an electro-magnetic field boundary. 11. Quarks also supposedly have a charge to them and then would also most likely have electro-magnetic fields associated with them, possibly a different arrangement for each of the six different type of quarks. 12. The interactions between the quarks EM forces are how and why protons and neutrons formulate as well as how and why protons and neutrons stay inside of the nucleus and do not just pass through as neutrinos do. THE GEM FORCE INTERACTIONS AND QUANTA: 13. Personally, I currently believe that the directional force in photons is "gravity". It's the force that makes the sine wave of EM energy go from a wide (maximum extension) to a point (minimum extension) of a moving photon and acts 90 degrees to the EM forces which act 90 degrees to each other. When the EM gets to maximum extension, "gravity" flips and EM goes to minimum, then "gravity" flips and goes back to maximum, etc, etc. A stationary photon would pulse from it's maximum extension to a point possibly even too small to detect, then back to maximum, etc, etc. 14. I also believe that a pulsating, swirling singularity (which is basically a pulsating, swirling 'gem' photon) is the energy unit in this universe. 15. When these pulsating, swirling energy units interact with other energy units, they tangle together and can interlock at times. Various shapes (strings, spheres, whatever) might be formed, which then create sub-atomic material, atoms, molecules, and everything in existence in this universe. 16. When the energy units unite and interlock together they would tend to stabilize and vibrate. 17. I believe there is probably a Photonic Theory Of The Atomic Structure. 18. Everything is basically "light" (photons) in a universe entirely filled with "light" (photons). THE MAGNETIC FORCE SPECIFICALLY: 19. When the electron with it's associated magnetic field goes around the proton with it's associated magnetic field, internal and external energy oscillations are set up. 20. When more than one atom is involved, and these energy frequencies align, they add together, specifically the magnetic field frequency. 21. I currently believe that this is where a line of flux originates from, aligned magnetic field frequencies. NOTES: 22. The Earth can be looked at as being a massive singular interacting photon with it's magnetic field, electrical surface field, and gravity, all three photonic forces all being 90 degrees from each other. 23. The flat spiral galaxy can be looked at as being a massive singular interacting photon with it's magnetic fields on each side of the plane of matter, the electrical field along the plane of matter, and gravity being directed towards the galactic center's black hole where the gravitational forces would meet, all three photonic forces all being 90 degrees from each other. 24. As below in the singularity, as above in the galaxy and probably universe as well. 25. I believe there are only two forces of nature, Gravity and EM, (GEM). Due to the stability of the GEM with the energy unit, this is also why the forces of nature haven't evolved by now. Of which with the current theory of understanding, how come the forces of nature haven't evolved by now since the original conditions acting upon the singularity aren't acting upon them like they originally were, billions of years have supposedly elapsed, in a universe that continues to expand and cool, with energy that could not be created nor destroyed would be getting less and less dense? My theory would seem to make more sense if in fact it is really true. I really wonder if it is in fact really true. 26. And the universe would be expanding due to these pulsating and interacting energy units and would also allow galaxies to collide, of which, how could galaxies ever collide if they are all speeding away from each other like is currently taught? DISCLAIMER: 27. As I as well as all of humanity truly do not know what we do not know, the above certainly could be wrong. It would have to be proved or disproved to know for more certainty.

One of the things I enjoy about math is how well everything works together. Like, in current year, I study all kinds of math, from calculus, to statistics, to set theory and proof writing. And I think a lot about how nice it is that everyone else already figured this stuff out. Listening to you talk about the invention of zero and how people literally had to change mathematics seems crazy to me. I imagine it was similar for fractions, irrational numbers and complex numbers. For all of mathematical history, there was a rule that said, "Nah, you can't have a number between 1 and 2," and then one day, someone said, "But what about 1 and a half?" and boom, fractions. "Can't take the square root of a negative value," boom, i comes around. It would be absolutely wild to be around for a significant change in math. What if I wake up one day and someone figures out how to divide by zero? It probably won't happen, but who knows?

[@jrstf]

We have significant changes in math all the time as children grow into adults. We teach young children about fractions. Only later do they realize a fraction is simply a division which hasn't been calculated. While describing a problem to a child I wrote a number with a decimal point, a line under it, and another number below the line. He accused me of mixing decimals and fractions. I had no idea what he was talking about. Seems he thought a line was used to write fractions and a division sign was used to write division. He hadn't quite reached the point where they would teach him they are both the same thing. Life is far more difficult when you don't grasp the concept needed to solve a particular problem.

Actually it is possible to imagine number line in this way. It is called residue classes of division by some number n, in this case 3600, i.e. we denote as 1 all of numbers which has residue 1 when they are divided to 3600, and so on till 3600. Then it is possible to write following expression 3600+3= 3. Then all of them located in circle, with starting with 0 which correspinds to 3600, and ending with 3600 which corresponds to 0. And 0 in this case won't make sense, cuz we can omit it and write 3600 instead

This makes it sound like the geometric sum is finite because the geometric sequence converges to zero. But that isn't true. While infinite sums can only have a finite value when the sequence of numbers added converges to zero, that alone is not enough. The famous harmonic series is a sum of smaller and smaller numbers, eventually approaching zero, but the sum itself is infinite.

[@kiga14]

Great work, but I wanted to push back on a few things: 1. We don't really know how prehistoric people "felt" about zero. You're probably on the right track when you say the issue really didn't come up. At least not for practical purposes. 2. The concept of the number line is modern. No one thought of multiplication as stretching rubber bands in ancient times, that I know of. The number line serves well to teach 0 and negative numbers today, and if that was ever how anyone thought about numbers, people would have been happy with 0 and negative numbers long ago. 3. Ancient mathematicians had geometry and had counting numbers. The Pythagoreans tried to merge the two by having lengths as multiples of other lengths, but the fact that the length of a side of a square and its diagonal cannot be both measured as whole numbers of the same length (what we would today call the irrationality of the square root of 2) forced the Greeks to separate geometry and counting numbers. The organization of Euclid's elements makes more sense once you realize this. 4. Thus, the notion of 0 has two different meanings: the geometric and the arithmetic. Geometrically, 0 is a line with no length, which even modern people would say is not a line at all (or some mathematicians would say is a degenerate case). Arithmetically, it's a matter of definition. What do you consider a counting number? Actually, the ancient Greeks didn't even consider 1 a number, since the term "number" implied you had a multiplicity of something. They called it a unit (or at least that's what my English translation of Euclid calls it). 5. For calculations: this is something most histories of 0 omit. Long before Fibonacci, people in Europe used the abacus. They were not doing calculations with pencil and paper, with rows of Roman numerals. The abacus represents numbers positionally, like we do today. The abacus was used throughout Eurasia and already existed over a millenium before Fibonacci. The predecessor to the abacus, available to the ancient Greeks and even earlier, was the counting board with pebbles, which is like an abacus without the rods to hold the beads. Same concept. The Chinese used counting rods instead of pebbles, and there is a numeral system based on it that is not the standard Chinese numeral system most people know today (see Suzhou numerals). Thus, having a 0 in a positional system is something that was used for quite some time. By the way, our word for "calculate" (and "calculus") comes from the Latin word "calculi", which means pebble. 6. The Mayans also had a positional numeral system in base 20, and had a symbol for 0 in this system. Though it might have predated the Maya. This predates the appearance of zero in our known Hindu sources. 7. The Greeks didn't think of Zeno's paradoxes in terms of 0, but rather infinity. They made a distinction between absolute infinity (which they knew led to paradoxes and suspected was incoherent as an idea) and potential infinity, meaning the result of an unending process of finite things. Archimedes's arguments about the area of the circle or volume of the sphere use notions of potential infinity. He basically came up with the notion of integration, but avoiding the problems with infinity. 8. In fact, the development of calculus depended on being willing to stretch notions of logic to some extent. What is dx? This is the sort of thing that would show to the Greeks that the whole thing was absurd, but Newton and Leibniz were willing to go with it because it seemed to explain the results of Fermat, Descartes, and others. But George Berkeley pointed out that it made no logical sense. Only the work of Bolzano, Weierstrass, Cauchy, and others helped make this rigorous, and that was in response to other paradoxes that had come up in the 19th century. 9. Negative numbers show up occasionally as possibilities in these numeration systems, but they are not used in algebra, especially in the days when algebra was only being applied to geometric things. See points #3 and #4 above. Indeed, Cardano's Ars Magna, he separates the cubic into a large number of cases like a cube equalling a multiple of x plus another number, versus a cube plus a multiple of x equalling a number, etc. because he couldn't just move all the terms to one side of the equation, whether they are positive or negative. This is the 1540s! I would argue that 0 (the number, not the numeral), and negative numbers, start making a difference in math only when you have algebra, because it helps merge all these different cases into one thing. Come to think of it, complex numbers play a similar role. 10. Do you have a source on the Church considering 0 to be of the devil? I don't know of one, and the Church is famous for writing all of its rules down and debating them. Nor am I aware of any Church teaching regarding 0 and the existence of God. Also, Aquinas was over a century after Fibonacci's work, but when he lays out the arguments for and against the existence of God, the number 0 does not merit even a mention. There is a Church doctrine about God creating the universe from "nothing" (ex nihilo) but since God and by some accounts the angels already existed, this is not a claim that "there was nothing" at the time, but rather that God was not shaping one thing into another, like when we "make" a chair out of wood and nails, but was just willing the universe into existence. Anyway, great work on bringing this stuff to KZbin. Seems like you've reached quite an enthusiastic audience.

[@zanebartlett8004]

Hello! After watching this, and then your video about if math is invented or discovered, I pondered for awhile. Without getting into the answer, a fun question I came up with that's related - "If physics happens, and a physicist isn't around to plot it, does it still make math?"

[@DarkSkay]

For the old question, if math is discovered or invented, I quite like the provocative answer: both. Since the term "invented" can be set to mean "discovered by the mind". An intuition relating to your question: in our world, our universe, all behind-the-scenes computation, enforcement of laws, causality and progression of time... appear "effortless", as if there was no "hesitation" and no "work" involved in making it function as it functions. But of course, that's only how it appears from the inside. Who knows, maybe Chronos sweats buckets ;)

[@zanebartlett8004]

@@DarkSkay Yeah my much longer reply was going to be something about how it feels like we're not addressing the real question which gets brought up at the end of that video about a re-framing of the question to be something like "Is our universe mathematical". Which I quite like over the initial phrasing because it better gets at a question worth answering. I agree with what you're saying though with that initial phrasing coming down to just a definition problem on the difference between "invent" and "discover". So I tried to think about the universe existing, just being there. That led me to spending like an hour reading about existence here on Standford - plato.stanford.edu/entries/existence/ If that's interesting, you might like this old vsauce video - kzbin.info/www/bejne/nIm6XoSgd9ilq6c Anyway, started spending too much time on this didn't really finish the thought, but the highlight was that funny question. Largely the unfinished conclusion I came to was, If you consider existence as something that can be perceived (debatable), you could say that things have mathematical properties that can be perceived, and in that way, math fits to me like geology or astrology. Something to be discovered. However, I feel like I'm stumbling over probably decades of philosophy that doesn't address things like "essence". A good part in that Standford piece is what use is it to say things "exist", quoting "What is the difference between a red apple and a red existing apple? To be red (or even to be an apple) it must already exist, as only existing things instantiate properties. (This principle-that existence is conceptually prior to predication-is rejected by Meinongians.) Saying it is red and an apple and furthermore exists is to say one thing too many". So again, I feel I don't have enough context to explain correctly, but I hope that I could, verbosely, get my point across.

[@DarkSkay]

There's also a rather open approach, where (as a first layer) you declare everything entity that at least satisfies logical identity. So, in principle everything that can enter our language, senses, hands, minds, imagination. Examples: the number 17, a red apple, redness, mister Bean, an online tax form, random notes on a guitar, dragons, the wind blowing through this valley in 3000 years from now, word, Turing machine, contradiction, Poseidon, joy, untruth, inertia, a teapot orbiting Jupiter, a cloud that looks like an elephant, maybe, Cynthia's poem, our mood yesterday. Even before attempts to qualify: there is an infinite supply of such entities that are receptive to being nested, connected and arranged in infinitely many ways - with relatively few rules limiting the possibilities (at least for our world and especially for our language & imagination). Some of those entities express "meta", transcendent, recursive or self-referencing, behaviour or ambition, e.g.: entity, being, real, observer, understanding and touching (begreifen), suffering, hoping, dreaming, "that what cannot be talked about", God(s), all, nothing etc. Contemplated on an abstract, open and general level, diverse answers can be thought as "willing" (perhaps pre-existing; like a stone waits for the sculptor, to reveal what is already contained) to embrace diverse questions, which in turn can always be refined or will freshly appear, using elements of previous answers.

The Chinese had a grid system that looked something like large graph paper. Where we would use a zero, they simply left the square blank.

[@marioalavegan5042]

[@altrag]

I would suspect not a whole lot difference to be honest. Why? Because physics. We really only have one more foundational leap to go (integrating gravity with quantum mechanics). We don't really have much of an idea how we'll get there, and there almost certainly will be some new mathematics involved, but I suspect it won't be anything as groundbreaking as the invention of calculus, topology or group theory has been in getting us through Newtonian mechanics and into modern physics. There's always the possibility of something completely unexpected of course, but the places where such a thing could hide are getting rarer and rarer by the year. We can already see practically to the edge of the (observable) universe - as much as we'll ever be able to see. There's a little more room for surprises on the quantum side of the scale but not _that_ much room given how much we already know about the two things we need to combine - and short of something coming completely out of left field we're not likely going to have the engineering capability to probe even that level for many generations to come. That's not to say there isn't plenty of things to be discovered in both math and physics, there absolutely are. I just don't see those discoveries being as game-changing as some of the prior stuff has been. We're not at the _end_ but we're close enough to see the finish line in the far-off distance.

@@altrag Science is never ending! For example relativity has spawned many many more questions than answers. Mass/energy equivalence was mentioned in passing by Newton ... but presumably he didn't have a plethora of doctoral students to investigate it like nowadays. Note if course that Einstein didn't either ... but he published and thus his ideas and knowledge was disseminated along with other scientists ideas and examined in great detail by others ... including the aforementioned doctoral students. Remember that "there are more scientists alive now than have ever existed before" ... and there is an enormous resource in the academic and other "industries" and Government (military-industrial) to finance and support them.

[@altrag]

@@simonblackham4987 Not really. There is an "end" to science. Once we have observed all we can observe even in theory, that's pretty much the end of it. We're certainly a long way away from that point, especially on the quantum side of the size scale. But that in itself is a bit of a problem - the next "obvious" step is so unbelievably far away that its unlikely we'll be able to take it for at least a few lifetimes. Namely, probing the Planck scale. I've seen it estimated that an LHC-style ring accelerator capable of reaching Planck energies would need to be approximately the size of Earth's orbit around the Sun. That is to say, we'd need to be a Dyson Sphere-capable species or damned close to it before that becomes practical from a purely engineering point of view. Of course, its perfectly possible in theory where we don't have to worry about trivial things like "costing trillions of dollars and requiring us to rip apart Mercury to get enough material to build it". But its not going to be happening in our lifetimes or that of our great grandchildren. Or maybe someone will invent some kind of device to reach similar energy scales while being a bit more realistic in terms of physical size and budgetary constraints. There's absolutely no known basis for how such a device might even theoretically work, but that falls squarely in the category of "its only impossible until somebody does it", so can't be ruled out. And.. that's about all we've got. We can build bigger and bigger colliders hoping that maybe some kind of supersymmetric particle will fall out, or maybe dark matter somehow merges with one of the other forces at an energy scale "only slightly beyond" what we currently can manage. But its all just "let's spend a trillion dollars and hope to hell". Unlike the LHC where we had at least one thing we were really really sure we'd find (the Higgs), the next accelerator would be purely a gamble. There is nothing "missing" from our knowledge until we hit the Planck scale. Of course, there could be something we don't even have a way to know is missing.. but there's many orders of magnitude between the LHC and the Planck scale. Such a hidden thing may be at 50TeV, but it could also be at 50PeV or 50EeV - and neither of those values are anywhere close to the Planck scale either. The next step that we know is a transition point (but believe we understand fairly well) would be the GUT scale where the strong and electroweak forces merge. But even that is way, way beyond any current or foreseeable-future accelerators (its about 13 orders of magnitude away - closer to that magic Planck scale than the LHC's capabilities). We simply have no leads for "reasonable" new physics in the next few hundred years is the problem. GR and QM are likely to stand for at least a similar amount of time as Newton's theories (which lasted around 400 years before Einstein came along). Sure there will be small tweaks here and there, maybe some reformulations, but I don't see any fundamental changes for a long, long time. That's not to say there's no work to be done. Astrophysics in particular is finding new stuff on a regular basis. But one thing to note is that the stuff they're finding tend to formulate new _solutions_ to GR. There hasn't been anything that points to a significant change in the underlying GR framework since the cosmological constant was recognized as an appropriate description for expansion. On the particle side of things, there's still lots of work to be done analyzing the stuff we do know - fields like condensed matter physics, attempting to build bigger and bigger atoms in hopes of finding the theorized "island of stability", searches for higher temperature superconductors, the list goes on and on. But again, they're all things that work within the framework of the standard model - nothing that would fundamentally alter the model. Its of course possible I'm wrong - I'm no better at predicting the future than anyone else. I certainly hope I'm wrong really, as that would be rather exciting. But unfortunately there's just nothing in our current theories that even vaguely hints at truly new physics being accessible in the foreseeable future. There is no modern equivalent to Newton recognizing that the ability to polish glass meant his corpuscular theory of light wasn't exactly correct (and even with that hint, it took a few hundred years for us to figure it out!) Not until we reach the Planck scale.

[@simonblackham4987]

@@altrag ... what makes you think there is an end to science? Its like the early pioneers thought that once computers had solved the important questions of the day we would no longer need them! Your (our) present knowledge doesn't allow us to imagine what we don't know.

Doesn't the possible existence of Dark matter and Dark energy hint that there is more undiscovered physics for us to find?

Numbers could not exist without shape! Pythagor(reincarnation of Euphorbos). Yes, roman abacuses numbers is a 1-positional(1-digit) number system with operator "*1000^n", which need not "0". If to "open" content of shape, then it will be broken to peaces! YES. So called negative numbers do not exists, and they a fake. They exist only for 4 active observers: '+', '-', '*', '/' composing Zero. Number line is a fake, line has no shape, has no closed content. DIVIDE/MULTIPLE BY ZERO MEANS THAT YOU CAN BE DISCONNECTED FROM NUMBERS BUT WHEN DISCONNECTED YOU NEVER CAN CONNECT TO THEM AGAIN. THIS LAW IS CALLED "INFINITY IS CLOSED BUT ZERO IS OPEN". ZERO IS OPEN AND IT'S IMPOSSIBLE "FROM ZERO TO HERO". Yes. Number theory is not perfect. Conclusion: Preface. Positional natural a-ary d-digit number systems can represent some kind of polytopes. For example: binary d-digit number system is a d-vertex simplex.(vertices is a numbers with digital root=1, edges is a numbers with digital root=2 and so on) 2^n-ary d-digit number system is a n*d-vertex simplex with 2^(n*d) faces (for simplexes externity is considered to be face). 3^n-ary d-digit number system is a d-cube. For n=1 d=2: if 1-chain (2 vertices + 1 edge) shift 1 times we receive 2-cube with 3^2=9 faces, i.e. square. For odd and not power -ary number systems: odd^n-ary d-digit number system is a d-cube_odd. For n=1 d=2: If (odd-1)/2-chain shift (odd-1)/2 times we receive 2-cube_odd with odd^2 faces. (2*3=6)^n-ary d-digit number system is a d-mebius. For n=1 d=2: If 3-ring (1D triangle) shift 3 times and "press" 1 chain into 1 vertex we recieve 2-mebius with 6^2=36 faces = 3 square + 2*3 triangles + 2*3*3 edges + (3-1)*(3+1)+1 vertices , because in 1D-rings shapeless Zero (wich in simplex is a Externity) is "pressed" into 1 vertex and can't generate new shapes . For even and not power -ary number systems: (2*odd)^n-ary d-digit number system is a d-mebius_odd. For n=1 d=2: If (odd-1)/2-ring shift (odd-1)/2 times and "press" 1 chain into 1 vertex we recieve 2-mebius_odd with (2*odd)^2 faces . Conclusion. All positional natural a-ary d-digit number systems with a^d numbers are represented by 3 types of d-polytopes (simplex, cube, mebius) with a^d faces . For me as a programer, it's curious to know that difference in faces between consequent such polytopes is hexagonal numbers. To enumerate more complex polytope may be used positional natural A-ary D-digit number system , (A)(D)simplician. Where A,D - some natural number sequence arbitrary but equal length. Then 2D Maya/Egypt pyramid is are positional natural (3,2)-ary (1,2)-digit number system or (3,2)(1,2)simplician. "No distinction between numbers and shape. Numbers could not exist without shape."

@Jim Allen so you are saying without the symbol "0" computer revolution could still happen as long as we represented null in some way?

[@HunterHogan]

For a digital machine (e.g., a computer), to accurately store data and to perform transformations on the data (e.g., multiply two whole-numbers), the data must be represented with a symbolic system that includes positional notation and all positions must be defined. As you know, a written representation of a whole number that uses so-called Arabic numerals is an example of positional notation. As you also know, In English and many other languages, if a "0" (zero) occupies a position in the positional notation, it means "the value of this position does not affect the value of the whole number represented by this symbol. You might not know that in the Arabic language, nine of the ten characters that represent the numerals one, two, three, four, five, six, seven, eight, nine, and zero have a very different appearance than the English symbols. The two symbols for the numeral nine, however, are similar: 9 vs. ٩. Arabic has a character that looks similar to 0. The Arabic character ٥ is the numerical character for five. Finally, in Arabic, zero is represented by the numerical character ٠. One conclusion: Yes, the character that represents zero is arbitrary. When English-speaking humans represent whole numbers with so-called Arabic numerals in positional notation and the rightmost position has the smallest value, we say that we can drop the leading zeros from the symbol without changing the value. For example, the symbol 000617 has the same value as 617. But computers cannot do this. A computer stores data in discrete sections that all have the exact same size. Importantly, the data is stored in a literal physical location. Contemporary computers always store data in symbols with eight positions. (The computer can combine two or more symbols to achieve 16, 24, 32, or more positions.) Hence, each physical location of the symbol has eight physical positions for the positional notation. In this case, the concept of "leading zeros" doesn't exist. All eight positions must be defined. This reason alone requires that computers use zero at least in the sense of "no value here" for positional notation. There are other reasons, but maybe this will help a little. (I'm too tired to continue writing.)

Since it exists as a value, saying 1/0 = infinity is fine, just fine.
