The structure that holds your biology in place as-is conforms to all things math. The structure of your brain is built upon beautiful mathematical functions. You did NOT invent that. Nor did you invent thinking in the way that we do it. In fact, thoughts and what they are escapes most people's understanding of Reality. You surely think I'm silly for saying it, but in the very distant future, all things "math" will be in the form of tune, tone and micro-rhythm.

The paradoxes are not truly paradoxes at all... The problem is that they pay more attention to what they think makes sense rather than what the Math is revealing about reality... The scenarios also imply certain things: 1. Linguistically, the expression is inaccurate for defining what a barber actually is. Essentially, it uses the fact of whether a man is un/shaved to suggest whether a man is a barber or not. 2. A man who is shaving himself is not being a barber at that time in the general sense, even if he is a barber by profession. 3. Also the scenario with the clippers is poorly interpreted... The clipper parts could be placed in the sink with the set of things that do not belong to clippers: if the parts belonged to a clipper that was removed from service due to malfunction. It is not our job to determine what the math should look like: our job is to practice consistency, which is the key to accuracy/equality.

[@milton7763]

The whole question of whether maths is invented or discovered seems to be more of a question of definition or semantics to me. In part 1 of this video it is stated that (verbal) languages are invented. But any mathematical equation can be expressed in words. Indeed, that is how you teach mathematics by talking students through what you are doing with the equations and operations. The fact that natural phenomena (things and occurrences) follow certain patterns and that those patterns can most easily/efficiently be described with maths, doesn’t mean to me that you’ve discovered the maths - you’ve discovered the pattern. This to me is analogous to certain human (emotional, social or cultural) phenomena that can only be or are most easily expressed in certain languages. There are, for example, many terms in Japanese that refer to cultural phenomena that you wouldn’t find in many (in some cases, any) other cultures. That doesn’t mean that when you learn about this as a non-Japanese person you are discovering the word, you are discovering the phenomenon. The word is just a tool to describe that phenomenon.

[@derekfrost8991]

Yes I had that idea during the documentary. The maths checks out because what it describes is really there. But then again, it can be there and not there at the same time..

[@christopherhorn5274]

Your paragraph 2 and 3 seem to be contradicting each other. Inventing a word is not the same as discovering a concept.

[@JohnDoe-xt6ow]

Many arguments boil down to definitions that one accepts or does not accept. For instance, what makes a surface smooth? There seems to be no such thing, really. Or what makes a species? Or . . .

[@fabrizioc3315]

It should be obvious at this point that mathematics is the tool our brain employs to describe the outside world. Pretty much like any other language our brain invented (words, music, art... you don’t really believe there is “music” out there, right? It just happens inside our brains...) The “coincidences”, such as finding a (quasi) spiral pattern in the nautilus and a similar (quasi) spiral pattern in the sunflower, are there just because the brain that is analyzing them is always the same, and of course it is using the same tools. We will hardly have a counter proof in the future, of a different brain describing to us how they perceive and describe the same outside world. Now, that would be really interesting! Maths makes predictions because our brain evolved as such. We make predictions all the time, in our daily life. Maths is an organized and rigorous (actually, the best we can do, but certainly not omnipotent) way of making predictions about what “could be” out there, based on what we currently perceive. Then we do experiments and check whether the prediction was right or wrong. In some cases (e.g. general relativity) it is perfectly right, in many others (e.g. string theory) it is far from right. The alternative to maths being entirely man-produced is that “god”, or something as platonic as that, is the underlying maker of our reality, and some yet to be “discovered” maths contains the answer to all questions. I find this latter explanation much, much less satisfactory than the former.

Here's what I find ironic about this series. The question she's asking seems tangentially related at best to the content, but it is quite a nice tour of a lot of esoteric math, physics, etc. To me, inventing math is like inventing a flashlight to explore a cave or inventing telescopes to explore the heavens... or inventing a language to describe day to day activities and objects. The objects/cave/heavens existed, the apparatus used to access and understand them is the part we invented.

[@innocentpaul513]

Thank you, Hannah, for giving a whole new perspective toward understanding mathematics. You are right in stating, that mathematics is little bit of invention and whole lot of discovery.

I'm at 12:49, where Hannah says math seems to be too good at predicting the behavior of the world in ways we never could have imagined. What if there were on one side Unimath, math from our Universe, a more fundamental coding language of our universe, and on the other side our math, a lense through which we discover parts of Unimath, a language that can translate some of the ideas of Unimath. Our math could be inspired by Unimath, but limited to what our type of living organisms can grasp of it. It is a language we can learn, a tool we can use, and it allows us to discover some of the behaviors of the world. But it is a narrow view of the Universe, and it may be bound to it by our own nature. It could even make some sense of some things while completely missing the bigger picture of those same things. I love the way the shadow of a cylinder can be a circle, as well as a rectangle, depending of where you shine light on it. And there might be other lenses capable of showing other things about our Universe, but we cannot use them of find them because we are not familiar with them.

The "multiverse" is not a solution to our paradoxes. All the solutions are here in our Universe. The Problem is within the human mind. Unification of General Relativity and Quantum Mechanics doesn't require complicated mathematics. Instead we need a simple explanation of "Space and Time INTERACTION" in just 2 Dimensions. Having the description of Space-time in 4 Dimensions is not sufficient because Space got 3 different appearances (3-D space, 2-D space and 1-D space). Consequently, there are 3 different levels of interaction between Space and Time. General Relativity focuses on 1 level only. This is the real Problem in Physics. We need to complete our understanding of RELATIVITY first by studying Gravity based on 2-Dimensional Space-Time.

Despite her PhD in maths, in the 3rd program in this series Dr. Hannah Fry demonstrates her fundamental misunderstanding of E=mc², of Special Relativity, of General Relativity, and of Quantum Physics. Spreading her misunderstanding to others can be misleading to those who wish to learn the correct theory. Until watching this program. 14m30s E=mc² applies to objects at rest. The mass of an object does not increase with increase in velocity, this is merely the "relativistic mass". 18m30s Two observers at the same position in spacetime will observe flashes of light (eg. from London and Southampton) at the same time, not at different times. It is the events which caused the flash of light which they will disagree about both in terms of the position of that event and the time that it happened. The stationary observer will consider that he is equidistant from Southampton and London, and that the flashes of light were emitted at the same time. Whereas, the observer travelling at near light speed, also seeing both flashes at the same time from the same position in spacetime, will consider London to be closer and Southampton further away, and therefore consider that the flash of light was emitted from Southampton earlier and from London later than that time which the stationary observer judged the event to have happened. Dr. Fry and Dr. Macarthur claim that the moving observer would see the flash of light from London sooner than the stationary observer despite being the same distance away from it. If this were true, then the light would have to travel at a faster speed towards the moving observer than it does towards the stationary observer... light does not travel at different speeds, it's just the observer's perception of the event which is altered by spacetime dilation due to relative motion between the observer and the event. 21m45s The first diagram used to illustrate the warping of spacetime due to a massive object is wrong. The field lines are not bent so as to diverge around the object, squashing the spacetime, they converge towards the center of it, stretching the spacetime. If the object was made from antimatter then the diagram would have been more accurate. 36m0s Attempting to include quantum physics into her program Dr. Fry says "...can all be reduced down into chemicals, which comprise elements, which themselves are made up of atoms..." I have no idea what Dr. Fry learned at school, but I recall learning that the elements ARE the atoms, and that all of the atoms ate listed in the periodic table of elements. 50m06s "...gravity simply doesn't apply to particles at the subatomic scale"... completely incorrect and absurd to suggest this, since if it didn't apply to the subatomic particles from which everything is made, then it would not apply to the larger scale objects either. The truth is that gravity DOES apply to all of the subatomic particles, including those which have no mass, eg. photons, since these too are affected by gravitational fields, eg. gravitational lensing. Overall, Dr. Fry seems utterly confused about which aspects of maths are discovered and which are invented, yet somehow managed to correctly conclude that it is a bit of both. However, she incorrectly states that the imaginary number "I" is invented, when such numbers are every bit as real as real numbers and fundamental to the nature of our universe.. the only thing to be invented was the name "I". She could have done a far better job of distinguishing between the mathematics which is inherent to the nature of reality, and those mathematical methods which have been invented to assist in calculation. Her attempts to include some basic physics and and chemistry into the discussion illustrate her ignorance of such subjects and could result in misleading the viewers, if they are not already knowledgeable in these areas. Fortunately my 14 year old son also understood the fundamental errors which I pointed out above.

18:31 Complete FAIL on the two animations here: Both the balloon and the airplane are fixed (unmoving) with respect to the background, while the plane is supposed to be moving "very fast". And even though the two flashes appear to go off simultaneously, the red circle starts expanding later than the white one (obviously not how light works), which is the only reason it reaches the plane later. (!!) As a result, the animations definitely DO NOT illustrate the effect being described. This could have been fixed so easily by just having the plane be moving toward London (with both the flashes and the expanding circles being in sync)!

set theory is really philosophy rather than math. for there to be a paradox, a crisis, an arbitrary assumption must be accepted. ie: a barber is only and forever a barber. this is simply absurd. in fact, a barber is a role that a human plays for a duration of time. a crucial part of the definition of a barber is that a barber is available to fulfill the role of a barber. a barber cannot shave himself and still be available to fulfill the service role of barber. as soon as the barber begins to shave themselves, they are no longer available to fulfill the role of a barber and thus are no longer a barber. there is absolutely no paradox to consider, the paradox was faulty from the beginning. on math invented vs discovered: discovering the language to talk about the palm tree and predict it being on a desert island is not discovering the palm tree itself or the nature of the desert island as if you traveled to them yourself. it's inventing a syntax to communicate about the palm tree's locus. math is a language, an abstraction, that changes and evolves, as all languages do, over time. it is added to and changed to fit the needs of those who find it insufficient to discuss their theories. the parts of the language that remain useful continue to stand the test of time. should the day come that we "understand" quantum mechanics, we will have made a discovery that leads to an invention of math language to explain it to each other. all realities are defined by the language used to describe them. so too will the quantum realm. it shouldn't be surprising we cannot describe yet what is so foreign to our experience. until we've built up enough observations to discuss and describe them in meaningful ways, the hyper micro/macro spaces and behaviors of the quantum realm will remain elusive. but it's entirely imaginable that someone will come along and have an "a-ha" moment that can describe it sufficiently that suddenly math provides the general populous a window into what was before a mystery. e=mc2. yet, even in this example, the imperfections will be a reality. einstein knew his biggest blunder: cosmological constant. math will forever be an attempt to describe our observations, or faith, depending on how far away from the applied you wish to journey.

The existence of maths independent from humans has long been obvious to me... I wouldn't even qualify it as a discovery in and of itself but simply an innate ability we have extended upon to a greater degree as we both evolved and progressed our imaginations, language and communication skills. Most creatures use maths, but of course we have explored it's potential to a much greater degree. A lion knows when "One" of "nine" of its fellow pride members dies and the next day knows that now only "eight" are on their "second" hunting attempt... It knows its position in a strategic crescent shaped hunting pattern and knows that "three" other lionesses are to its right and "four" more pride members are to its left and that together they are attempting to take down "One" prey... A crude example amongst many in the animal kingdom but a clear one... How they conceive of those numbers is unknown to us of course, you may as well try and imagine what the world looks like to a bat!... And they are not about to start clawing tally marks on a stick for memories sake but conceive of those numbers they simply must.

[@derekfrost8991]

Catching up with math is difficult because it is an external tool. It gets you from A to B to C to D....., etc., but IT is doing the work, NOT the mind. This can be a pain for some folk when they are trying to understand things such as Einstein's Special Relativity(SR), since much of it is often presented via math. I found it much easier to discover SR first by discovering the cause of it, and then after that convert it into mathematical equations. You can actually create a very simple geometric representation of SR, and then use it to derive the SR mathematical equations, and do so in mere minutes. Pity that they don't teach this in schools. By the way, "making something move", is actually the changing of the direction of an objects continuous motion in Space-Time. If you make it move faster across space, it will now be moving slower across the dimension of time, since in truth you have simply changed its direction of ongoing travel in Space-Time. The faster you have set an objects motion across space, the slower a time frame the object is now in, and thus more energy is required for you to speed up its spatial motion even further. From your point of view, you may have doubled its spatial speed, but from its point of view in its slow time frame, you may have quadrupled its spatial speed, hence the explanation of the increase in the required energy to do so.

[@new-knowledge8040]

Space-Time exists. It is a 4D environment. It has its own set of laws of physics. Our 3D reality, that resides within it, also has a unique set of laws of physics. Thus we have both quantum mechanics, along with relativistic mechanics. When a 4D Space-Time event occurs, it seems bizarre in deed from a mere 3D point of view. If you measure one particle of an entangled pair, your measuring it is simply a component of an overall 4D event. 4D events extend across both space and time. However, in the 3D world, you are confined to the "NOW" time, and thus only can see a thin slice of a 4D event, that being the spatial part of it. Hence one only sees one particle of an entangled pair effecting the other that is positioned from it a distance away in space.

The issue of the barber is not about contradiction in maths, but rather in the subtleties of human interactions. The barber is a cultural construct about employment and service.

Why do some people draw a line through their sevens? It's an unnecessary extra stroke and makes it look like a backwards F.

[@Meinstein]

@@theoneandonlyhermit8021 That is the same sort of unreasonable answer that I always get when I ask this question. Obviously a 7 with a line through it looks more like a 4 than a seven without it does. Doesn't it?

[@robbannstrom]

It's standard practice here in Germany to write a seven by hand with a horizontal stoke through its' middle. It's also the case here that a 1 is often written by hand with such a long leading stroke (the normally-little diagonal stroke before the long vertical stroke), that it can look something like a Greek capital lambda. I guess the horizontal stroke through the 7 is used to distinguish between the two?

[@Meinstein]

@@robbannstrom a two looks nothing like a seven. A two has a stroke at the bottom.. a seven does not. If anything, that slash distinguishes a seven from a one.. and even then, we don't make a one with a stroke at the top.

Well, with the Barber's Paradox and the clipper/not clipper set paradox, can't we create a third set for those elements that fit neither set? _And,_ if a person shaves himself then isn't he in fact _also_ a barber? For me, 'mathematics' is becoming more and more like a sophisticated 'word-game' that produces descriptions so precise that they lead to paradoxes thus necessitating _new_ descriptions which themselves eventually lead to a paradox and on and to until we end up with an infinite number of descriptions to describe a finite set of elements. What if the barber goes to _another_ barber in order to be shaved: does that mean he is _not_ in fact a barber? This is why we get absurdities such as 'infinitely dense' singularities and so forth.In other words, I am saying that there is an 'Ultraviolet Catastrophe' embedded in the roots of _any_ descriptive language which, I would argue, is what lead to 'discovery'. Just a quick philosophical point. :)

[@noahbody9782]

All we have are the counting numbers: 0,1,2,3, etc and a few basic operations. The rest of mathematics is just a form of shorthand for things we cannot do. Counting numbers may correspond to groups of objects in the physical world e.g. apples. If we have 5 apples, we can add 2 apples to get 7 apples, 5 + 2 = 7. We can give away three apples, 7 - 3 = 4. But we obviously cannot now give away 6 apples as we now only have only 4 apples. What we do is replace 4 - 6 with the equivalent 0 - 2 and then replace with the shorthand notation -2. We cannot have -2 apples or -2 of anything. We use a shorthand notation to remember what we wanted to do in the hope that we may get more apples in the future. Then we can give away the 6 apples as desired. Similarly, if we have 12 apples, we can divide the apples into 3 equal groups of 4 i.e. 12/3 = 4. However, we cannot divide 12 apples into 5 equal groups, 12/5. This is physically impossible unless we change our apples by cutting them up. Then we are no longer dealing with objects that are apples but objects that are pieces of apples. We use another equivalence that 12/5 is the same as 24/10 and we use another shorthand notation 24/10 = 2.4. We then hope that in the future we will get more apples such that we can divide our apples into 5 equal groups. Similarly, we can take the square root of 9 to get 3. Square root is just a special case of division. But we cannot take the square root of 8. We just use another shorthand √8. We hope that we will be able to multiply √8 with another √8 and then we can get back to the number 8. Same deal with √-1. We just hope that we will get another √-1 to multiply it by. In mathematics we just have addition of two numbers, subtraction of a smaller number from a larger number, multiplication of two numbers (repeated addition), and division of number by one of its factors (repeated subtraction). These are things we can do in the real world with physical objects. All other operations are impossible. When we can’t do an operation, we just use shorthand notations to “remember” the operation in the hope that at some latter time we can eliminate the impossible operations and return to the counting numbers that represent real world objects. We can use tricks such as replacing meters with millimetres or nanometres or the Planck length to eliminate impossible divisions. But this is just the same as cutting our apples in halves and having 12 apple halves as opposed to 6 apples. We have then redefined our physical objects. Even the symbols used for the counting numbers are just a shorthand notation for repeated addition in that 1 + 1 = 2, 1 + 1 + 1 = 3, etc. When someone tells you the Universe is mathematical, remember that all the mathematics you have ever seen just starts by assigning counting numbers to groups of objects and applying the operations mentioned in the last paragraph. The rest is just a form of shorthand for things that can’t be done, but we hope will eventually be possible.
