What is Zero? Getting Something from Nothing - with Hannah Fry

Is zero really a number? How did it come about? Hannah Fry tells the story of how zero went from nothing to something.

Once upon a time, zero wasn’t really a number. Its journey to the fully fledged number we know and love today was a meandering one. Today, zero is both a placeholder, and tool, within our number system signifying an absence of a value, and as a number in its own right.
But it wasn’t always seen as that, and it still doesn’t act quite like other numbers. Can you divide by zero, for example? Hannah Fry explains how zero came about, from its origins in ancient civilisations, through the resistance it faced from the Roman numeral system, to being the cornerstone of calculus.

Can we take a little moment to appreciate the fact that they numbered their chapters beginning with zero (which is common in computer science, but not in every day life) and numbered the chapters in binary, just so they could better show off zero?

[@davidvaldes3456]

"0 is the absence of a value" how then could a chapter be represented as 0? Its great intention but it needs to beigin at 1 . Zero should only be used if there are no chapters. 0 chapters, chapter 1 cant just be called chapter 0. Its not cute lol

Emptiness, void, nothingness and Shunya are deeply philosophical concepts that ancient Hindus gave considerable thought and importance. In Hinduism everything seems to have originated from a void or a point which eventually took the shape of a number 0. So in many ways Zero is also a concept and an idea even before it is a number.

Thanks for this beautiful upload, but I require a bit of enlightenment, if you please! I trust this video is primarily based on Charles Seife's 'Zero: The Biography of a Dangerous Idea'. Was a little flummoxed to find many a people attribute its invention to Aryabhata, when his book indeed says what you said, Professor Fry: many civilisations have invented a vague concept of zero on their own volition, but it was the Indian mathematician who popularised the same. On the other facet, the book emphatically affirms, which obviously sounds quite a logical claim, that it's none but Babylonians-people who hail from a place often regarded as the 'cradle of civilisation'-who invented the idea of zero. Is there a veracity in this claim, Professor Fry?

Whenever people ask why isn’t 1/0 infinity the answer always seems to be ‘infinity isn’t a number it’s a concept’. Well, isn’t maths as a whole a concept in itself? It just seems that people are bent on not getting infinity as an answer?

[@abdallaahmed780]

I believe 1/0 is infinity

[@SatyaVenugopal]

The problem is that 1/0 could just as easily be negative infinity as well. When something can simultaneously be equal to multiple different things that aren't equal to one another, we've got a contradiction. That's kinda the point: 1/0 gives contradictory answers if we think about it in different ways. So 1/0 can't be infinity. It's undefined. (Within every day maths. Funky stuff happens when you go into funky maths.) What we can say is that if we divided 1 by ever smaller positive numbers (i.e. positive numbers that get closer and closer to 0 each repetition), the answers would tend towards positive infinity. And if we divided 1 by ever smaller negative numbers (i.e. negative numbers that get closer and closer to 0 each repetition), the answers would tend towards negative infinity. Also, when people say infinity isn't a number, it's a concept, that's a meaningful statement. All numbers are also concepts, but not all concepts are numbers. Infinity is one of the latter. If you really wanted to call it a number, it doesn't behave like any other number. If you add 1 to any number it just gets 1 bigger. If you take 1 away from any number, it gets one smaller. If you multiply any number by 2, it doubles, and dividing by 2 halves it. Multiplying a number by itself squares it. And so on. But if you add 1 to infinity, it's still just infinity. And ditto for subtracting, multiplication, and so on. (And some of the operations make even less sense.) And all this is before we even talk about the various different kinds of infinities, and different kinds of funky maths. So regardless of what anyone believes, 1/0 ain't infinity.

NOTE FOR AMERICAN VIEWERS: 2:33 By "Roman Empire", she means Byzantium, the eastern empire that survived for centuries after the fall of Rome. Although Byzantium had once belonged to Rome, it was Greek-speaking and had a somewhat different culture, and was influenced at first by Persia and later the Islamic empires.

[@dorakemba2899]

"Byzantine" is a late term coined by historians. Nobody used the term "byzantine" as a selfdesignation back then. But Romanoi ("roman citizen"), but still hold onto their non-roman ethnicity. Roman Empire was, like every empire, multi-ethnical. So no; the eastern Roman Empire was not _only_ "greek speaking". But inhabited by many different folks that spoke different languages/dielects. Greek was the lingua franca, the language of the elite, ruling class. That means: Church + royalty. Byzantine is just used by historians to divide the Roman Empire to East (konstantinople)/West (milano, rome). The lingua francas of the Roman Empire were not only latin but also greek. Which a lot ppl clearly forget (or don't know). Latin f.e. vocabulary is full of loanwords from ancient greek. Latin also borrowed from etruscan, celtic, semitic and other (still spoken and extinct) languages - so did also greeks. They were always in contact with other folks. But since the roman empire, that lasted a *very* long time and caused a lot extinctions of languages - we'll never know from where many words actually really came from. Also: there was no "islamic empire" in Greece. You mean probably the Ottoman "Empire" (the invading turkic tribe). But Ottoman "Empire" was actually not an _empire._

1 chicken / 0 chickens = remainder 1 chicken. Long division still works with 0 when you use remainders. Is there any mathematical value to that? Probably not... but it still isn't undefined. It becomes an issue when you try to apply it to other equations though because 1/0 != (3/2)-1 != (5/4)-1 etc... since remainder 1 can have completely different values given a different context. Remainder really equals the dividend to be used over the same divisor. I.E. 3/2 = 1+(r1/2) so in the case of 1/0 the remainder of 1 = 1/0 which obviously loops infinitely. Perhaps there is some math there with convergent series using other /0 remainders or something, I don't know.

[@MephLeo]

+vipero07 Yes, that is true. But lets look at it from another perspective: how would you characterize a division where the reminder is equal to the dividend?

Wait, if 1*0=0, shouldn't 1/0=1? I mean you take 1, and divide by nothing, so you're not doing anything to that 1, so shouldn't it just be a 1? What's with the divide by zero error?

[@lukesteeves1291]

+cidshroom You should check out the concept of limits! One of the major problems with trying to give x/0 a value is that it doesn't have a single limit. For example, if you graph 1/x, and start on the positive side of the x axis, (eg 1/10, or some other positive number) and you start picking denominators closer and closer to 0, the value of the function gets very big - it actually does approach infinity! but this is only from the right side - if you did the same thing, but started on the negative side of the x axis, the values race off to negative infinity! Thus, the function 1/x has no limit at 0 - dividing by 0 doesn't yield one specific value!

[@cidshroom]

Luke Steeves Ah, that makes far more sense, I didn't even think to try it with variables. I'll look into this, seems very interesting. Thank you!

[@gorgolyt]

+cidshroom 2*0 = 0 = 3*0. If 1/0 has an answer then multiply both sides by it. 2*0/0 = 2 = 3 = 3*0/0 But 2 is not 3. So 1/0 can't have an answer.

[@ravegraveyard]

In simple words, the remainder would be 1 not the quotient. Quotient can be anything because 0* any number is 0. So the quotient of 1/0 can be any number. Hence infinity.

When defining something as having nothing in it such as a hollow ball, would it be correct to say that within that nothingness, is a quantity of 1 cavity within it? I'm not trying to just use words to twist things up, I'm referring to how math always seems to have an exception to the rule and how things change when we get down to molecular states or quantum states. Because of how our dimension potentially interacts with other dimensions, could this be one method of getting something out of nothing?

But is there anything _outside_ the number system that can confirm that the distance between 1 and -1 is 2? (To me, it seems infinite.) Numbers are representatives of relative quantity. They all represent some quantity more or less than the quantities represented by other numbers. But just as 'infinity' is not a number, but, rather the absolute, non-relative concept of infinite quantity; so too, is 'zero' not a number, but, rather, the absolute, non-relative concept of infinite non-quantity. The absolute absence of quantity, in other words, and thus not a proper number. We use Zero for place holders to represent empty orders of magnitude. It's very useful and convenient, because our minds are finite capacity, so that we can not work with infinite digits. But that is a quality of our minds' abilities, not of external reality itself. An omniscient mind would have no need of a zero place holder, but, rather, would do math with infinite single digits. To me, both of our uses of zero are convenient, but ultimately misleading. And I think this has potentially extremely far reaching consequences for both math and physics. For example, in our number system, we understand that infinity is not a number, so that infinity - 1 is still infinity, basically, because you simply can't subtract a number from a non-number. But when it comes to zero we don't recognize that. So we allow that 0+1 = 1, and so on. But does that correspond to reality? I would say that in reality, if there is true, absolute nothing, there's nothing to add or subtract. It is an immutable absolute conceptual state. So that 0+/- anything still = zero, just as infinity +/- anything still equals infinity. Because you can't add or subtract anything from absolutes, because absolutes are immutable and timeless. They're not measurements of quantity. And measurements of quantity, btw, are divisions of everything. It's probably best, imo. to think of zero and infinity as the opening and closing brackets of the set [All] . Ultimately, they are the same, the duel expressions of the boundary of [All]. Note that this doesn't work _within_ our number system. But consider that she said in the video that Calculus works so well because it avoids having to divide by zero. It's not that our system for numerical notation and the math we do with it works so well _because_ of using zero as a digit. Rather, we manage to make it work very well specifically by _avoiding_ the paradoxes caused by using an immutable absolute concept as the lowest number in the number system(a system of relative quantities.)

+theDuffChimp Zero is an even number. A number which quantifies a count or an amount of a null size. If you have zero siblings, then you have no siblings, if something has zero weight, then the thing in question has no weight. If the difference between the number of pieces in two piles is zero, it means the two piles have equal amount of pieces. Before counting starts, the result can be assumed to be zero; that is the number of items counted before you count the first item and counting the first item brings them to one. Non-mathematicians argue that you cannot have zero of something. Mathematicians accept zero as a number, since you could have zero of something. It is mathematicians, and most others, which accept zero as a number ;)

[@hrgwea]

It's true that zero was initially a placeholder, but that's no longer the case. Today it's just a number and nothing more. Each digit in a number contributes a quantity defined as: DIGIT × 10 ^ POS. Where POS is the ordinal position of the digit from right to left starting by zero. For example, the value of the sequence of digits "300" is defined as: 0 × 10^0 + 0 × 10^1 + 3 × 10^2. There are no placeholders, just numbers.

[@grantkohler7612]

All numbers are just concepts when they are not bound to the rules of physical existence by units of measurement. If you choose to bind it to reality, then there is no addition or subtraction of zero units, and zero units also can not be divided into smaller units, nor can you have any multiples of zero units. You can use logic systems to understand what would happen if the rules of reality were different. Mathematics when attached to units of measurement is one such logic system. There is apparently another one philosophers use, but I have never grasped it's use of symbols.

[@D33PTHINKA]

If you divide anything by no-thing then there is no division. I don't get why it is so hard for many mathematicians to acknowledge that the issues and requirement for special considerations with zero are of their own creation. Algebra being the main culprit causing confusion. It seems simple and intuitive. 1+0=1. 1-0=1. 1*0=0. Yet divide by zero and suddenly the definition of 0 changes? 0 is none, no-thing, absence within the context of whatever things you are discussing (As in: Using a numeral describe how many chicken emojis exist in this sentence). So if we divide 1 chicken by no chickens (bad example) or 1 centimetre by 0 centimetres we are making no change as the function is negated and there is 0 division. We could try to carry out the function as a subtraction and find ourselves in infinite iterations because as someone else commented 0 goes into any number infinite times...but this is simply not true because 0*x=0. Zero provides context, an interdependent opposite to denotations of value or magnitude. If you have a box of zero and you divide it with a zero width division, x times, there is no division. 0 is the argument at which the value of a function is negated and disappears. It is not positive or negative or even or odd, it is a denotation representing the concept "no-thing" and hence is clearly defined. Not undefined or infinite. Zero as a numeral is confusing because in contradiction to its core meaning it also has a value in mathematics in terms of indicating magnitude in multiples of ten. With the right axioms maths can "prove" anything but that doesn't make it true. See Gödel's work. It is a miracle that maths is as useful as it is to science when it is an incomplete, often misunderstood and contradictory theory.

[@cjmacq-vg8um]

fine video, but I love it win "science" plunges into illogic... multiplying AND dividing by 0 is identical to doing those things by 1. dividing by 1 is like multiplying by 1, you remain with original number you started with... you aren't added or subtracting anything from the original number. since 0 has no value, when multiplying and dividing by it, you are in fact not multiplying or dividing at all and you arrive at the original number. that sounds logical to me. good vid!

There are no words to describe what Zero is, and we can only describe what "Zero is nothing." Zero (ṣifr in Arabic and צפר in Hebrew) to indicate an empty position. With the help of the natural history of "zero," and the use of "zero" as a starting point, one may consider two types of metaphysics. On the one hand, the epistemological metaphysics, based on the perceptual/rational dichotomy, is related to the zero as a vacancy between numbers. On the other hand, the genetic metaphysics, based on the dichotomy of source-evolution (or origin and derivative), has much to do with the zero as a number between negative and positive numbers. In this respect, zero represents the horizon of metaphysics: we can forever approach it, but we cannot ultimately arrive at it. Though serving as the point of convergence and divergence for all relationships, zero has no definable content of its own. Such is the essence of zero, and of metaphysics as well. For example, there are as many numbers in between 0 and 1 as there are from 1 to the mathematical infinite ∞. This is due to the fact that each number n with n going from 1 to ∞ has an invert number 1/n which tends towards 0 a n tends towards ∞. The limit of 1/x with x tending towards ∞ is 0, and vice versa, 1/x with x tending towards 0 has ∞ as its limit. It can be asked whether space extends infinitely in every direction, and it can be asked whether time extends infinitely in either of the two temporal “directions”. Just as one can ask whether, if space is finite, it has an “end” (whether it is bounded or unbounded), one may ask of time whether, if it is finite, it had a beginning or will have an end or whether it might have neither, but rather be “circular” (be finite but unbounded). As one can ask whether there could be two extended objects that were not spatially related to each other, one can ask whether there could be two events that were not temporally related to each other. One can ask whether space is (a) a real thing-a substance-a thing that exists independently of its inhabitants, or (b) a mere system of relations among those inhabitants. And one can ask the same question about time. It may also be that there is no internal unity to metaphysics. More strongly, perhaps there is no such thing as metaphysics-or at least nothing that deserves to be called a science or a study or a discipline. Perhaps, as some philosophers have proposed, no metaphysical statement or theory is either true or false. Or perhaps, as others have proposed, metaphysical theories have truth-values, but it is impossible to find out what they are. There is no GOD except A-L-L-H (Aleph-Lamed-Lamed-Hah) the last prophet Mohammad. Aleph is infinity - Lamed-Lamed is the Almighty One - Hah all good and love (associated with 99 Names). Mohammad is the space time messenger and not a Robot. Epistemology, put simply, is the study of knowledge. In particular, epistemology focuses on how we come to acquire knowledge and what types of limits there are to our knowledge. In other words, how do we know what is true? I want you to convince me that you are not a robot. What will you say to help me know you're human? Can you ever know for sure that you're not a robot? A different branch of philosophy deals with a related question: What is real? The study of reality is known as metaphysics. It focuses on determining what, if anything, can be said to be real.

Whatever you said this nothing gone inside of my brain but I like the video...

[@eXanova]

There are only to numbers in existence... Zero and one... Zero indicating an absence and one represents presence... On vs off and so on... The accumulation of numbers then represents sequence... So 7 is not a number in itself but rather a sequence of ones that re occur until it represents "7" occurrences... We need to reevaluate our understanding of numbers...

[@edpad5824]

It was difficult for my math students to respect a mathematical concept of zero. To the average person, it means empty, nada in our pockets, in a room, or in our poor love life. But these examples apply to counting what we see: it's our visual bias. Putting 0 on a number line does not indicate no--thing (empty space) as in our lives, but a location on a number line. It's a median between negative numbers & positive numbers. When we cross a two-way traffic street, we hope to reach the median: the middle of the two way traffic before us and behind us. So zero on a number line is just a location. We could define any number on the number line as the middle number that splits two sets of numbers. Blame it on nada, zero, zilch! On teaching algebra, it's hard to divest the popular quantitative approach to zero versus a zipcode called zero: location on a number line Don't tell the negative & positive numbers about this!

Hello there, can I get myself a chance to contribute my translation to you guys? I would like to translate this video into Vietnamese . Thank you.

[@grahamgrafx]

Can you explain why anything to the power of zero is one? I believe it's related to the concept that zero actually means nothing rather than a number.

[@abhirassharma]

x^1 = x,, dividing both side by x, x^0 = x/x = 1

[@krabkit]

X/0 only approaches infinity for positive values of x, for negative values it approaches negative infinity. that is why x/0 is not infinity. the simplest analogy i can think of is the gaps in the graph of tan(x) where it curves up to infinity then suddenly appears coming up from negative infinity

[@EllipticGeometry]

+krabcat Almost right. You mean 1/x approaches ∞ as x approaches 0 from positive values, and -∞ from negative values. When x=0, 1/x is nothing meaningful. At best you can make it an abstract kind of number that becomes 1 when you multiply it by x. Note that allowing for this kills all the usual assumptions you can make that make math useful. That's why we don't normally do this. As for graphings things, why not just 1/x?

[@gorgolyt]

+krabcat How would you prove +infinity and -infinity are different numbers? Look up the Riemann sphere.

Can anyone please tell me with which programm this video was made?

Nothing is something. At least under the POV of Directed Intelligence. What does that mean? How does meaning mean? Meaningful conversations appreciated.

[@tomdubbs]

I think that 'Something' is an unspecified 'Thing', where as, 'Nothing' is specifically 'No Thing', a 'Void'. In the same way, to classify 'Front' we need to recognise 'No Front' (Back) and for 'In' we need 'No In' (Out), etc. These must all be from the POV of a subjective intelligence because these intrinsic pairs of class are meaningless when divided or unrecognised. For there to be 'Things', we need to recognise an absence of 'Things' to classify them - as being not 'No Thing'. A 'Thing' only moves into a 'No Thing' (void) because a 'Thing' cannot move into another 'Thing'. If it moves, it will have to move other 'Things' into 'No Thing' (void). If 'Nothing' is recognised as a 'Something', then how is it classified? What is it paired with? What is 'No Something'? What would I mean if I asked you to: - Imagine nothing? Draw nothing? Do nothing? etc - Imagine no thing? Draw no thing? Do no thing? etc I think as an abstraction 'Nothing' (a void) is 'Something', as with any subject of class, but in context 'Nothing' is 'No Thing', objectively implied as not a thing, and void of all things. I think it must be the same for Zero, so I would subjectively classify it as a 'No Number'.

0 was devloped in india🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳and I also indian🇮🇳🇮🇳🇮🇳🇮🇳🇮🇳😊

[@lumri2002]

According to our college professor the decimal number system was based in Hindu-Arabic number system where basic digits of counting use 1, 2, 3, 4, 5, 6, 7, 8, 9 that were adapted by Arabs from Indians, but the Arabs also added the 0 to the number system. I don't know how accurate such information, we may investigate. Zero may have just been a concept used by the Indians in philosophy during ancient times, but perhaps the Arabs may have been the ones that used it early as numeral. On the other hand the ancient Mayan civilization in South America separately developed vigesimal number system which included zero numeral.

[@user-uj2tk2tv3z]

No

[@thomaskennedy5728]

Nope,arabs didn't add zero. Zero was added by aryabhatta The father of algebra i.e Muhammad ibn Musa Al-Khwarizmi mentioned or cited some of his discovery including function of zero. If it was arabs who discovered zero in mathmatics then he wouldn't mention him. Aryabhatta was the first person to use zero in mathmatics to do sum, subtraction and multiplication.

[@Demoflower477]

I was thinking this I was like if zero isn’t a positive number so it’s a negative but there’s no such thing as -0 if there was zero would be a positive

Thanks aryabhatta

[@AvadhutPurohit]

There is a philosophy called "Saankhya Darshan." Darshan in sanskrit means 'to see' or philosophy. Saankhya gave rise to 'Sankhyaa' the numbers in sanskrit. 0 in Vedas is not nothingness. It is exactly opposite. It is 'complete'. Read the shanti mantra that defines this. "om poornamada poornamidam poornaat purnam udachyate. Poornasya poornamadaya poornam ewa awashishyate" It means if you add completeness to complete, you get complete. If you completely remove completeness, completeness still remains. After 9, that location is NOT nothing. It is complete.... That's 0 and then you move to next place.... I don't know if West knows this.... If anyone can take credit of zero then it is only "Saankhya philosophy" and vedic sukta....

[@Nawaf-]

This video tells us how the number came to be. It does not tells us what it is... the title should be “history of number zero” not “what is zero”... you still did not mention the answer to that question. What is zero?

[@Nawaf-]

Here are some interesting facts about the number zero. We like to think of it as an empty quantity, but if we pay attention, there are positive numbers and a mirror negative for each positive number, which when combined, give us zero... (+5)+(-5)=0 both mirrors of the number 5 can be represented at the same time by zero. So, zero actually represents an empty quantity (-5) AND a full quantity (+5), *at the same time, in the same space* What? In reality, it represents the existence AND absence of all numbers of a thing *in the same time/space.* Example: A zero quantity apples in a box. Actually means, all possible apple numbers exist in this box as well as the absence of them exists at the same time in this box. That is very confusing to think of. I know. That’s why I like it. If we say there are zero apples in a box. Mathematically, it means there are (let’s say) 5 apples exist, and the same 5 apples don’t exist *at the same time* Therefor, an empty space should not be represented by a zero. It should be represented by a negative number of what you are looking for. Example: This box has a -5 apples. Since I’m looking for +5 apples and cannot find it. If I’m not looking for a specific number of a specific thing... let’s say I’m looking for *anything at all* in that box. It should be calculated as: *Box contains a negative infinite quantity of anything* So, what is zero?? My brain will explode. My theory is: Zero is everything and nothing at the same time. If that is correct, then we cannot experience zero in reality. Which I think is sad 😨

[@edelcorrallira]

wow, beautiful!

[@elliotgale470]

The answer is infinity. You could say that 1 + 1 is not actually 2 because numbers are just concepts if you wanted, but that's not a very good argument.

[@zachcrawford5]

X divided by zero IS infinity (assuming X>0 or X

[@hrgwea]

X divided by Y is Z only if Y times Z is X. So... X divided by infinity is undefined, because there is no number Z that multiplied by infinity is X.

[@aarong7555]

Undefined and infinity....are kinda the same thing

[@hrgwea]

Galactic Galaxle Far from it. Infinity is a concept, whereas undefined means "no result".

[@gutmorgensurfen]

I also like to add a pendulum theory, like high and low tides. Everyone is so linear

[@lucidmoses]

Hang on a minute. You can't say infinity is just a concept. All numbers are just conceptual.

[@MephLeo]

+Lucid Moses Yeah, but infinity can't be used in calculations. you don't add to infinity, nor subtract from it, because it will always result in infinity. So, it has no practical use, only conceptual use.

[@lucidmoses]

Leopoldo Aranha I see. So X / 0 is not infinity because infinity is not a number infinity is not a number because it has no piratical use. X / 0 equals infinity is a piratical use. But X / 0 is not infinity because infinity is not a number infinity is not a number because it has no piratical use. X / 0 equals infinity is a piratical use. But X / 0 is not infinity because infinity is not a number infinity is not a number because it has no piratical use. X / 0 equals infinity is a piratical use. Etc.. etc..

[@MephLeo]

Lucid Moses I like your spell of practical. It is a typo, but it also says something about pirating a logic. Mathematical concepts set does contain the concepts of numbers, but numbers set _only_ contain the concept of numbers. Infinity isn't a concept for a number, as it has no defined quantity. Such as that, infinity, while as much of a mathematical concept as a number, isn't a number.

[@lucidmoses]

Leopoldo Aranha yea, but the same reasoning is true for zero. You can't count zero any more then you can count infinity.

[@MephLeo]

Lucid Moses Nope. Zero does have a defined quantity, or, better saying, it has no quantity at all. Infinity, on the other hand, has a quantity that is not defined and can't be defined in any way whatsoever. See the difference?

Every number can have a corresponding relationship in the material world except for zero. It is impossible to have zero of anything. Even in binary computing systems it only implies a length of time between 1s.
