David^2 - S^2 = Cohen^2 gives us a hint: the "D" from David stands for Donut, the S stands for Sign and the C stands for Colossal donut. When homer points at the colossal donut, we can see all of these 3 points (donut, sign, colosal donut) in one frame. If we connect these 3 points we get a triangle where a is the height of the sign including the colosal donut. You can also measure the angle of homers arms (alpha): 10, and the credits give us the number 24m as the length of b. We can now calculate the length of the hypothenose c: 24/cos(10) which is 24.3. Now we can calculate a: sin(10)*24.8 which is about ~4m. This means that the man holding the colosal donut plus the colosal donut is 4 meters high. They are about the same size so we can divide by 2 to get the size of the colosal donut: 2 meters!!!

He even tested the Scarecrow Theorem in non-Euclidean geometry! I didn’t see that coming.

It works on a sphere when you ignore the any sides part. You can create a triangle were two of the sides equal a quarter of the circumference of the sphere and the other one spans around the equator. The angels between the equator line and the other two are always 90°, therefor the triangle is iscosceles. The third side can now vary from 0 to the circumference of the sphere. So if you subtract the other two sides (which equal half of the circumference) you still got the possibility to have half of the circumference left. Since in this example a equals b 2*(square root of a * square root b) equals 4*a. Since a equals a quarter of the circumference you get the solution when c spans the whole circumference. It doesn't look like a triangle but technically it is a triangle on a sphere I guess.

In spherical geometry opposite points on the sphere are considered equivalent: this is because it changes the 5th postulate to say that parallel lines do not exist: lines can only be maximum circles (circles made by a place cutting the center of the sphere). All lines are perpendicular and cross at ONE point: so they consider the opposite points as one single point. So some of those points on your bigger side are part of the original triangle and the others are excedent like a side prolonged even ending on the same points. The distance in Riemannian geometry is given by the SMALLER maximum circle because a metric can not be a multivalued function and the metric by definition must obey the triangular inequality (or the hell will go loose and several contradictions arise because the metric should capture the intuitive notion of distance as being additive, and being symmetrical (in a loose sense that I am too lazy to explain). So your construction is not a triangle is a triangle with line segments added (my explanation is a little convoluted because I am lazy, maybe later I explain better).

There are examples in which an instance of that formula, sqrt(s)=sqrt(x)+sqrt(y) may be found. The triangle inequality is reversed in Minkowski space, so that's a candidate. Secondly, it might be possible to find instances of that on some surfaces, such as a variant of the pseudosphere or some other surface of revolution of some cusp-containing curve. Finally, something similar to it can be found in particular Lp spaces. For example, a space with a norm |s|^p = |x|^p + |y|^p will have something akin to the required formula for, say, p=1/2 What I find very intriguing about the last option is that circles, when drawn on a euclidean plane, will look like Lamé curves (with the power parameter being 1/2). In short it can be done in spaces with a quasi-norm.

This guy was simply amazing. Kind of sad, put in all those endless hours of head splitting work, worry, study, panic, study more, obsess, and in the end I have to periodically give myself math test so I don't forget all of it. everything today is charts, computers, and more charts. I remember i started my job and could figure everything with mobil calculator, pencil, and paper. Co-workers were jealous I believe and said why figure it out like that it's in the tables. One professor I had said - I feel sorry for you if technology ever crashes. At The time I didn't care The exams were so damn long and hard that without a calculator I would have had a nervous breakdown trying to crunch it all before I ran out of time. Now I understand though. The most important stuff you will need in life is college algebra and geometry maybe some trig but probably not. However when you have that knowledge it feels good. In a job interview I got asked a math problem and immediately pointed out the flaw in the question and offered a math solution to solve it. The other mathlete in the room laughed and of course no job for me. However, it felt damn good.

At around 7 minutes, trying to make the Mutilated Pythagorean Theorem (MPT) work on a spherical triangle - the triangle you show won't satisfy it, but there are spherical triangles that do. If you put the apex at a pole, and _c_ along the equator, then _a_ and _b_ are ¼-great-circle arcs ( _a_ = _b_ = ½πR), and _c_ can be any length in the open interval, 0 E.g., if R = 2/π, then _a_ = _b_ = 1, 0 If you make _a_ = _b_ a little shorter than 1 and at slightly different "longitudes", then they can be adjusted so that the great circle joining them the long way, will be _c_ = _4a_ = _4b_ , and the MPT will hold. [Interesting to note: the MPT is homogeneous of degree ½, so it scales by any constant factor without changing.]

Maybe it's a triangle on a cone. Varying 3D cones have different degrees, like cones that have 10 degrees or 37 degrees even 50 degrees. So the isosceles triangle is on a cone, where the remaining side cuts through the cone exactly and the first two same sides indicate the degrees of the cone. So maybe it's an "isosceles cone", and the formula is actually a way to measure the circumference of the bottom of the cone. It looks triangular from a certain angle, until you realize that it's 3D! So it's possible that it's the formula to calculate the circumference of the bottom of the cone. From there, maybe the cone height and even the cone volume can be calculated. And it we know the weight of the cone, we can use the formula "D=m/v" to calculate the cone density and then put it through the density experiment to see if it floats on oil or sinks in honey or floats on water or maybe floating in alcohol or lamp oil or sinking in galinstan liquid metal alloy. Or maybe it's a pac man cone. An incomplete cone with two sides that meet up in the bottom forming a pac man shape at the bottom of the pac man cone.

You can construct an other isoceles triangle with the equal sides which are still a and the remaining size which would be b' =/= b. Assuming the theorem mentionned is true, you have that sqrt(a) = sqrt( b )/2 = sqrt( b' )/2 which is a contradiction.

+nico.og Cool :)

It can be done on the surface of a cone where the largest side of a triangle is towards the base of the cone compared to the other sides. Also after boiling down variables, I came to a = b + sqrt(2ab) to satisfy sqrt(c)=sqrt(a)+sqrt(b) where a is not equal to b and all three are real non zero numbers. It was a few napkins long of some algebra but it's possible there is a small mistake in there.

Maybe intended, maybe sheer luck, but the first frozen scene: 1 mirror + 2 sinks = 3 stalls (left) + 5 stalls (right) = 8 tiles in lenght

You can't violate the triangle inequality, a+b>c, with some weird surface because no matter what surface and metric you're using, by definition the metric has to satisfy the triangle inequality. The only way is if you choose the sides of the triangle to be something other than geodesics (shortest paths), in which case you don't really have a triangle, just some 3 vertex shape.

+Jelle (NL) Ah, yes, that's a nice one. There are actually two occurrences of "counterexamples" to Fermat's last theorem in the Simpsons. The one you mention is the second one. The first one pops up in Homer^3 (Homer cubed) where Homer stumbles into a 3d world. Very neat stuff. There is also one mention of Fermat's little theorem in the Futurama Simpsons crossover episode.

+Mathologer keep the counterexamples in quotation marks. As per the numberphile video those are only close to a solution, not exact. (even the parity of the sum is wrong). P.S. just to make sure no one thanks Ferma's last theorem is debunked.

if you take an hyperbolic plan build on a cone with an angle enough close to 2π, I think you can make a triangle that will satisfy the condition of a+b

It is possible on a sphere if the longest side almost stretches around the whole sphere and the rest is normal. It will make every side connected to each other, so I think it still counts as a triangle.

There is no metric space where this equality could happen. In particular it is not true for any space with metric (Riemannian manifold: en.wikipedia.org/wiki/Riemannian_manifold), the sphere included. In such a strange world we would have a distance function which is does not satisfy the triangular inequality ...

3:05 He got a brain just not a very good one.

It can't work with any triangle since every triangle respects the triangle inequality - no matter in which space we embed it. One would have to give up the requirement that the points are connected by geodesics. As long as c is a geodesic a+b

In my language, isosceles triage is called as "equal feet triage" and right angle triage is called as "bracket triage". Maybe that's why we not confuse with both.

7:00 The answer is *never* on any Riemannian manifold ... if "length" is defined as *geodesic distance* ... because the geodesic is the *shortest distance* between two points, which forces the triangle inequality. Now, on a *pseudo-Riemannian* manifold (even flat, like Minkowski space), that's another story. This leads naturally to a question for you: do the flight distances of New York, Miami, Chicago and Houston fit in *any* Euclidean geometry, if they are treated as straight lines? If not, then what's the minimum curvature they must have before they do? What about other sets of 4 cities on the Earth, like London, Tokyo, New York and Johannesburg? Which geometries will 4 cities fit on, as a function of how much curvature their flight paths are endowed with? (Yes, some cases require a 2+1 dimensional Minkowski Geometry). What about 5 or 6 cities? And since the Earth is *not* a sphere, what happens if you try to fit 6 cities, as a function of the curvature you give all the flight paths, assuming they're all given the same curvature? How much information can be said about the dimensions of the Earth - as well as the cities' *latitudes and relative longitudes* - on the assumption that the 6 cities fit on a ellipsoid? Try it with { New York, Miami, Chicago, Houston, Los Angeles, Seattle}, as well as {London, New York, Tokyo, Johannesburg, Melbourne, Rio de Janeiro}.

Sorry - geodesics are NOT necessarily the shortest routes between any two points. Geodesics are only LOCALLY the shortest routes between two oints.

I know this is old but I'm going to take a crack at these Pythagorean clips. In the first clip, David S. Cohen's name is written as "David^2+S.^2 = Cohen^2", quite clever ;) Of course, the second time around, A^2+B^2 = C^2 is just on the "MATH BOOK"

I know this is a dumb question...I guess I'm just not nerdy enough, but I don't get the joke. how is "David squared plus S squared = Cohen squared" clever? Is there some hidden meaning? Is there some sort of language wordplay thing going on there? I understand the pythagorean theorem, I understand the reference, but I don't get the joke.

I did the calculations thinking that David^2+S.^2 = Cohen^2 would correlate numerically, if, for example, each letter associated with a number value (A=1, B=2, C=3)... but I didn't find anything. Someone can check my math, but I got DAVID (4+1+22+9+14)=40^2= 1400 Plus S (19)=19^2=361, so together 1961 equals COHEN (3+15+8+5+14)=45^2=2025. So, all together, 1961=2025 which obviously doesn't add up.

Tim Westchester 1400+361=1761, not 1961.

One instance where it works? Lets say the circumference of the sphere is 2... Lets have the side c be equal to maybe 1.5 and then the other two sides can just connect from the end points of the side c... That would make a+b

One instance on a sphere where this might work is a sphere so small that the end points of the c side are closer together on the back side of the sphere than when you follow the line between them

He got the brain, went to Australia and became matematician.

It could work with complex numbers where i*i=-1, then: a*i + b*i +2sqrt(a*b*i*i) = a*i + b*i - 2sqrt(a*b) = c*i might lead to some solutions. p.s. oh... its 5 years old - saw 5th of september and didnt noticed the year :D

The video suggested drawing a triangle on a sphere but a+b>c is still satisfied. If you draw a triangle on an ellipsoid you can get lines where a+b>c is now false. Think of a football cut in half from one pointed end to the other. the a and b lines come down from the center on the top to the center on the sides. The c line starts at the bottom of a, around the ellipse towards the small rounded end and back to the bottom of b. The real question is whether a triangle drawn on something other than a flat plane can still be considered a triangle.

I wonder if the point was that the scare crow didn't really get a brain. He just had to think he did. The líon just had to think he had courage and the tin man had to think he got a heart. Which is kind of an interesting angle from when I was a kid and I literally thought they had somehow actually received these things.
