Since I like fancy names I decided to call it "grocery list". Quite catchy, isn't it? I suspect similar technology might be at work here, too.

In America, most people take a course called “Precalculus” in which one part focuses on graphing in the polar coordinate system. They introduce a handful of curves, including the the lemniscate, along with cardioids or rose petal curves to graph. Its not so much a ‘grand finale’ as in my experience they just give the equation and what it looks like, then ask you to try and graph it in different scaled versions or orientations, and thats it. We don’t really learn any properties besides how to graph them in polar.

That ending is probably the best moment in Standup Maths history.

I mean “popular” music references are fine and all, but why hasn’t anyone realised that the final scene was likely an Annual General Meeting of Matts? Where they used the Arithmetic Geometric Mean of Matt-1 and Matt-2 to determine Future-Matt’s n-value? (~1.45679… if you’re wondering)

I just can't believe you did a video about this!!!! I have been thinking about this like for 3 years!!! OMG

loving your edits and commical self aware storylines. :)

Alternative idea for an average: Taking the inverse tangent of both numbers, take the average of their angles (a sort of average slope) and then take the tangent of this inverse average. You get the cube of the Golden Ratio as the average of 2 and ∞.

After some working out, given two numbers a and b, this "mean" can be written algebraically as k + sqrt(k^2 + 1) where k = (ab - 1)/(a + b) . For a = 2 and b --> ∞, k --> a = 2 itself and thus you obtain 2 + sqrt(5) , which is the cube of the golden ratio since φ^3 = 2φ + 1 = 2 + sqrt(5) .

I forgot, and then realized halfway through, that Matt was drawing all the equations in icing. Nice touch.

Oh my god this is brilliant! For my first job I had to draw the 2d cross section of multiple copper wires squashed into cylinder (the wiring within an electric car engine motor). These shapes began as circles and were squashed slowly into squircles as you added more wires, or reduced the cross sectional area of the cylinder (I know technically they would be compressed to hexagons, but a squircle provided near-accurate predictions and was more simple). I still remember my moment of pride, completing my first coding task ever, allowing a dynamically chosen number of wires to change the picture on the screen, slowly becoming more square as you added more. Better yet, these wires had insulation and copper components, so drawing a compressed squircle within a squircle within a cylinder was quite the challenge! Ahh how I miss my old job.

Matt talking to past/present/future versions of himself brings back positive memories of send emails to "Future Me", and I love how happy it makes him.

For practical applications I use the diagonal. You make a function where you give the diagonal and it gives you back the exponent. Then you enter the ari.mean between the radius and half the square's diagonal.

So what you're saying is that π = 4. Got it.

A small observation I found interesting, the harmonic mean between n=1 (which leads to the square on it's side) and "n=infinity" if we assume we can use infinity as a number (which leads to a square) is 2 which gives a circle. So in certain way a circle is the midpoint between a square and a square, which intuitively makes a lot of sense to me.

I already thought this channel was great, but this is just the icing on the Lemniscate!

The important question is how many times we think we've been seeing Matt 1 when actually it was Matt 2... For example the sink spinning video, where we thought Matt took a sink on a plane to Australia, maybe it was just Matt 2. And who's to say that there's just 2? Maybe there's an infinite number of Matts and it's just Matt all the way down

Even in this video we probably only saw two Matts, since Future-Matt is likely - though not conclusively proven to be - the extension of Matt-1 or Matt-2 through 4D space-time, or even some sort of hybridisation of both their respective timelines. That got me thinking… Do you suppose when Matt-1 and Matt-2 get together to determine Future-Matt’s n value (the value of n for Matt-n = Future-Matt) they held an Annual General Meeting of Matts and determined the best way of determining the correct n value for the relevant Future-Matt and used the Arithmetic Geometric Mean of the Matts in attendance?

6:00 If you look at a vertical line as an "infinite" slope, sort of like how we call a flat line a zero slope, then we can accept 1 (a perfectly diagonal line) as the halfway point between 0 and infinity, 2 as the halfway point between 1 and infinity, 4 as the halfway point between 2 and infinity, etc. I think slopes are a pretty good analogy for the harmonic mean concept; also, the reimann sphere is cool: en.wikipedia.org/wiki/Riemann_sphere

@@wrOngplan3t that's true, most of the issues we have dealing with infinity come from the fact that we treat positive infinity and negative infinity as separate things. But the reimann sphere concept proposes that negative infinity wraps back around to positive infinity, which fixes a lot of the problems we have with taking limits, dividing by zero, etc.(for whatever reason this idea is controversial) Infinity doesn't necessarily have to have a sign, it can be sort of like 0 and for thousands of years, mathematicians didn't even know what to do with 0 so I think accepting infinity as a number is going to be the next step towards a better mathematical framework.

I love this. I have a lot of fun explaining the significance of what we learn from the "squaring the circle" problem and how linear math doesn't play nicely with the geometry of circles. This is the bridge between those two irreconcilable differences and it's very interesting to see this worked out in math.

I was trying to look up a particular figure 8 shaped cookie from my childhood, and what I found instead is a Swedish/Norwegian cookie called a Kringla.

And then we dipped half of the cookie in chocolate.
