# Graduate Student Solves Decades-Old Conway Knot Problem

May 20, 2020 7:16 AM Subscribe

It took Lisa Piccirillo less than a week to answer a long-standing question about a strange knot discovered over half a century ago by the legendary John Conway.

Lisa Piccirillo’s solution to the Conway knot problem helped her land a tenure-track position at the Massachusetts Institute of Technology.

When [Piccirillo] first started studying mathematics in college, she didn’t stand out as a “standard golden child math prodigy,” said Elisenda Grigsby, one of Piccirillo’s professors at Boston College. Rather, it was Piccirillo’s creativity that caught Grigsby’s eye.This is nice. I like stories where victory doesn't rest on the gifted-by-birth hero*ine, but rather on chopping wood and carrying water.

Admit it, "that knot is slice" sounds like slang from a not-particularly-well-written cyberpunk novel from about 1990.

The engineer in me wants to understand problems like this but I know that my mathematical limitations were pushed hard enough by differential equations and Calculus III such that the understanding of higher (highest?) level proofs and theorems such as this will always have to exist in the abstract rather than technical realm.

I am never-endingly impressed by the individuals whose minds work in such a fashion however. Their grasp of the necessary skills and ingenuity to apply them are one of the key reasons (and justifications to be clearer, perhaps) for humanity's continual advance and improvement. Well done and I wish her luck at MIT.

I'm going to be picky and say she's not a graduate student; she's a "postdoctoral fellow," meaning, she has a Ph.D. and is researching with a professor, probably to get experience for a faculty position.

(Post-docs are an interesting beast -- neither student nor staff nor faculty -- and have none of the protections that come with those classifications. Hopefully this proof will get her into and keep her in a tenure-track position somewhere, if that is her goal.)

@zsh2v1 This is the kind of story that kept me out of graduate school: If I can't solve a 50-year-old problem accidentally,

Also, she was a grad student when this work was done (paper shows a submission date of 15 August 2018) so the headline isn't totally inaccurate.

I love the long history of giving students a hard problem that they're either not really supposed to know how to solve yet (high school teachers asking you to add up 1,2,3 ... 98,99,100 for extra credit before you've had algebra) or unknown problems that have been around for a long time that they don't know that it's an unsolved problem so they just solve it anyway. There are a bunch of these in math history, I think it's a bit easier to do this sort of trick question in math than in say biology or philosophy.

And kudos to the women in STEM. I've long known that there's no particular reason why anybody can't do some fancy math once they figure out how to do it their way. Ages and ages ago I tutored a girl failing algebra. We spent a couple of months mostly giggling and having laughs over her little sister's crush on the math tutor while just re-framing algebra into something fun. A couple months in my services were no longer needed because her grades were way up. She went on to get her masters in some branch of math. Probably knows way more than I do.

It's sorta sad that there needs to be a thing that it was a woman who did this thing. It should really be a 50/50 split sort of thing and not really worth mentioning over the fact that someone solved this previously unsolved thing that's been laying around for a long time.

I know that's the framing of the story, and it's reinforced by the photographs (look, she's young! she rides a bike!), but she was very close to completing her PhD (in a field adjacent to knot theory) when she worked this out. So she's only naive in the sense that she didn't recognize the Conway Knot as a problem because she wasn't super-focused on knots. So not an expert-expert, but pretty expert.

*But our world is four-dimensional if we include time as a dimension, so it is natural to ask if there is a corresponding theory of knots in 4D space.*

Every time I see these articles about 4D space I get confused by how they are presented. Am I correct to assume that we are really talking about four spatial dimensions here and not three plus time, which is always how four dimensions are introduced?

I like Erica Klarreich's science writing a lot, but this paragraph is a pretty good example of why non-mathematicians like myself have such difficulty with understanding higher-dimension topics:

To understand a thing in nD space, first think about the thing in 3d, but then think about it in nD.

*It’s hard to visualize a knotted sphere in 4D space, but it helps to first think about an ordinary sphere in 3D space. If you slice through it, you’ll see an unknotted loop. But when you slice through a knotted sphere in 4D space, you might see a knotted loop instead (or possibly an unknotted loop or a link of several loops, depending on where you slice).*To understand a thing in nD space, first think about the thing in 3d, but then think about it in nD.

4d space is a little bit over complicated here, I think.

Consider the usual 2d plane. A neat trick is to put a single point at infinity, to "close up" the plane into a sphere. So any geometry you do on a plane, you can also do on the surface of a sphere, so long as there's some single point on the sphere that you don't need to use. And so long as you don't care about distances, which we don't in knot theory: it's all about stretching things around, and distances never matter.

Now the same trick can be used to turn 3d space into the surface of a 4d sphere: just as a point at infinity. You don't have to try to visualize it; it just works by analogy... So all of the cool knot theory we do can be done on the surface of a 4d sphere with no real changes.

Now, a knot is just a circle that's twisted up in itself somehow. It's also a very 3d thing: given a fourth dimension to work in, you can turn any knot into just a circle.

Ok... So now I can explain what this slice thing is about. Mathematicians care a lot about

So all knots are just circles, right? And circles are the boundary of a disk. So, question: can we find a specific disk that a given knot is a boundary of? Well, easily, if you can have as many dimensions as you want...

But if you restrict things so that the disk had to be in that 4d ball that we talked about up to, the answer is "sometimes." And this is what "sliceness" is about. Can you find the 2d disc in 4d space that this particular knot bounds?

It's basically a high dimensional coloring problem... Can you color in the knot without having any funky crossings, etc, in the disk that you color in?

**boundaries**. Like a lot, a lot. A circle is the boundary of a disk, and a sphere is the boundary of a ball. (And really, a disk is just a 2 dimensional ball, and a circle is a 1d sphere. So it's enough to say that a sphere is a boundary of a disk.) It turns out that if you take the boundary of a boundary, you get nothing... A circle bounds a disk, but has no edges itself.So all knots are just circles, right? And circles are the boundary of a disk. So, question: can we find a specific disk that a given knot is a boundary of? Well, easily, if you can have as many dimensions as you want...

Sorry if that was snippy, but I see too many "this untrained person did X thing scientists couldn't!" stories where it turns out that they were trained but just didn't have the credential or something. It's bad storytelling, and I think it encourages cranks. This FPP on Harlen Bretz is a case in point. The "high school teacher" who solved the mystery was a high school teacher when he went "huh, I wonder what happened here?" by the time he answer that, he'd earned a PhD in Geology.

Anyway, I didn't mean to be a jerk about it, but I'm editing a book chapter, and it's irritability-inducing.

>> A neat trick is to put a single point at infinity, to "close up" the plane into a sphere.

Here's~~three~~ four ways to think about it, some of which might make it clearer.

Mathematicians typically have a lot of stories and analogies about these things, which make them easier to think about. All of these come to mind for me when I think about 'how is a plane like a sphere?' When I try to think about these things, I kinda go through my set of stories about spheres until I find one that's a pretty good match for the discussion at hand. Each story takes a bit of time to play with and draw and internalize, and after that, it's an idea on hand that I can use whenever I need it. Nothing here is about super powers; it's just accumulating a bunch of stories and tools to help understand these things that we have a hard time actually visualizing.

a) Very informal: Start with a round piece of cloth with a 'drawstring' at the edge, and draw the string tight until the boundary is just a point... What shape do you get? A sphere: just fill in that point.

b) Place a sphere on top of the plane. Two points determine a line... For any point on the sphere, draw the line connecting it to the north pole, then extend the line to hit the plane. Now every point on the sphere has a point on the plane. Vice versa, for any point on the plane, connect it to the north pole, and the line intersects the sphere somewhere. (maybe twice; if so, just use the point in the south pole.) So, there's a correspondence between points on the sphere and points on the plane... It's also a 'smooth' correspondence: if you draw a squiggle on the plane, it will 'project' to a kinda deformed squiggle on the sphere. (This is called 'stereographic projection.' Here's a picture.) [This also works in 2d... Draw a circle on top of a line, and connect points on the line to the 'north pole' of the circle. It's much easier to draw!]

c) 'Inversion.' Draw a unit circle (radius 1) on a plane. We're going to 'flip' points inside the circle to points outside the circle. Pick a point anywhere on the plane, and draw the line connecting it to the center of the circle. This line has some length d. Pick the point on the line at distance 1/d from the center. If d > 1, then 1/d < 1, so we send a point outside the circle to the inside. If d < 1, the reverse happens. Inside and outside flip, and points on the circle stay the same. The only point that doesn't have a 'pair' is the center of the circle, which has distance 0... We can then 'fill in' a point at infinity to pair with the center. This shows we can fill in a single point at infinity in a nice way, at least.

d) If you make a sphere really really big, it seems like it's flat. The curvature gets 'diluted' until eventually you can have flat soccer fields and such. There's still a tiny bit of curvature there, until the sphere is infinitely big... And then you're just standing on a plane. (This doesn't explain the 'point at infinity,' though.)

I always liked the Flatland analogy of shadows used to explain higher dimensions. If you take a sphere in our 3d world and shine a light on it, it leaves a circular or oval-like shadow on a 2d surface. If you shine a light on a circle, it will leave the shadow of a line on a 1d line segment. Extending this, if you shined a light on a hypersphere living in a 4d world, it would leave a sphere as a shadow in our world.

More complicated objects leave different shadows as they move. If you shine a light on a cube in 3d, the shadow it leaves on a piece of paper changes as you move and rotate the cube. If you were a Flatlander, a creature on a 2d surface, you might not be able to visualize a cube or other 3d object, but you might get a sense of how it works by the different shadows it leaves in your 2d world.
