Breitbart isn\'t the most reliable source. They do provide a link to the paper

https://arxiv.org/abs/2303.10798

but it has four authors - David Smith, Joseph Samuel Myers, Craig S. Kaplan, Chaim Goodman-Strauss.

New Scientist reports the story a little differently

https://www.newscientist.com/article/2365363-mathematicians-discover-shape-that-can-tile-a-wall-and-never-repeat/

David Smith may have found the shape, but it took expert help to prove that it was non-repeating.

The maths behind Penrose Tiles has been known for decades.
How is this different?

Because it uses only one tile shape. Penrose used two. Based upon my extensive expertise in the subject from 30 seconds of reading the article in the popular literature...

The Breitbart article seemed rather level- headed without a political agenda to it. I didn\'t know they were capable of it. Or it may have been a dig at the academic establishment, because it was an \"outsider\" with limited mathematical training who accomplished something, thought to be impossible by the establishment experts, using plain old \"common sense.\"

They ruined it when they quoted the Stanford professor ( of math ) who doesn\'t know squat about physics, chemistry, or \"other fields.\"

We\'re going to see quite a lot of the age old conjectural quandaries start to crumble once AI becomes more pervasive. It\'s kinda sad to see something people of the past spent decades of their lives on be obliterated in a sub-millisecond flash by an AI machine. Actually not sad.

This wasn\'t any age-old conjectural quandary. Penrose came up with an aperiodic tiling in the 1960\'s, and this a one-tile solution to the same problem.. Computers are handy tools for doing big exhaustive searches, but they don\'t obliterate anything.

There\'s no suggestion that \"the establishment\" thought that it was \"impossible\", and aperiodic tiling isn\'t the kind of problem that you can solve with plain old common sense.

It is a decidedly exotic problem, and you need appreciable mathematical sophistication to realise that the problem actually exists.

I can\'t see how.

Other articles say it was considered impossible.

> and aperiodic tiling isn\'t the kind of problem that you can solve with plain old common sense.

Okay, but as proved in this case, it can be solved with a hunch. Just guessing here, but all the broad mathematically generalized characteristics such a tile must necessarily possess, however voluminous, wasn\'t helping anyone get to square one finding an actual tile. Once a prospective tile shape was found, then it worked out fairly smoothly for them to show it was aperiodic.

It is a decidedly exotic problem, and you need appreciable mathematical sophistication to realise that the problem actually exists.

Mathematical sophistication yes, appreciable no. Graduate level abstract algebra is not appreciable.

I can\'t see how.

It\'s obviously a disingenuous appeal for funding abstract nonsense of no practical use.

Which you can\'t cite. English language science journalists can be pretty unreliable. New Scientist does better than most of them.

and aperiodic tiling isn\'t the kind of problem that you can solve with plain old common sense.

Okay, but as proved in this case, it can be solved with a hunch.

What this case proves is that there is one example of a single shape that can offer aperiodic tiling. Neither article says how David Smith came up with the shape. so the \"hunch\" is your invention.

> Just guessing here, but all the broad mathematically generalized characteristics such a tile must necessarily possess, however voluminous, wasn\'t helping anyone get to square one finding an actual tile. Once a prospective tile shape was found, then it worked out fairly smoothly for them to show it was aperiodic.

Not that you can list any of the \"broad mathematically generalised charasteristics\". You are just blowing smoke.

It is a decidedly exotic problem, and you need appreciable mathematical sophistication to realise that the problem actually exists.

Mathematical sophistication yes, appreciable no. Graduate level abstract algebra is not appreciable.

\"Graduate level abstract algebra\"? All algebra is abstract,. How do you split out \"graduate level algebra\"? You are pontficating again.

They ruined it when they quoted the Stanford professor ( of math ) who doesn\'t know squat about physics, chemistry, or \"other fields.\"

I can\'t see how.

It\'s obviously a disingenuous appeal for funding abstract nonsense of no practical use.

Abstract knowledge wouldn\'t be abstract if it did have a practical use, and when somebody finds a practical for it it can pay off generously.

Looking at the shape I was reminded of a few of the poly-cyclic aromatic hydrocarbons I had to study in third year organic chemistry. If you start embedding nitrogen molecules in the rings you get pentagonal elements. An aperiodic flat repeating polymer with long conjugated bonds could do all kinds of interesting stuff.

might have fun with it. He was levitating frogs in a powerful magnetic field when he and I were both living in Nijmegen (not that we ever met) but now he\'s into single layers of graphene.

It\'s not an unattractive tile, or pattern. I wonder when they will be in production?

Mathematical proofs that will stand up to scrutiny require experts but
it still required the intuition of a human to find the right shape.

It is an interesting one and breaks a widely held belief about what is
actually possible in tiling a 2D plane - not unlike Penrose tiling.

You are over optimistic about the timescales but in some domains where a
combination of brute force and deep learnable heuristics can triumph I
suspect several of the famous outstandingly difficult mathematical
challenges may fall to AI within the next decade (perhaps sooner).

Machines don\'t get bored or make trivial typo mistakes like we do.

I never expected to see a computer that could master Go and yet now
there are several that can bootstrap ab initio from the basic rules and
surpass the best human players in under a month.

Draughts turned out to be misleadingly simple. Chess was a tougher nut
to crack requiring initially dedicated parallel hardware (but now it is
hard to find a serious chess program that can\'t beat a human GM).

Go seemed to be intractable with so many possible moves and game states.

I\'ve seen a human do exactly that, when my neighbour, aircraft designer
Henry Millicer, solved the problem of minimising wing root turbulence -
a seriously difficult 3D problem. Books had been written and lives spent
on this, when he pointed out that any solution to the problem can be
reduced to an iterated 2D problem, solvable by an undergraduate using
only 2nd order ODE\'s. That invention is responsible for the
characteristic shape of the wing-fuselage junction you see in modern
airliners.

Most CPU\'s these days already contain chunks of stuff designed
exclusively by AI. It makes a lot fewer mistakes than a human -
especially on boring repetitive stuff and awkward edge cases.

Intel is working on its own neuromorphic designs to challenge Nvidia in
that market. It isn\'t clear which of them will gain most market share.
What is certain is that current CPUs are now way more complex than any
individual human can fully understand. The next generation will have
substantial parts designed by an AI to use fewer gates and less power to
implement the same functionality.

It will, and will do it the exact same way you design stuff. Previous attempts at automation were completely different, they didn\'t have close to the computational speed and resources available to the modern AI tools.

Probably not. John Larkin\'s design skills aren\'t great.

> Previous attempts at automation were completely different, they didn\'t have close to the computational speed and resources available to the modern AI tools.

Doing the same thing much faster isn\'t \"completely different\", though it may look that way to the customer. The way that essentially identical ideas get patented by different people on different continents at much the same time does suggest that the human brain is a pretty efficient search engine. It isn\'t always clear what it is searching through, though I can name one case where it was a particular issue of the journal of cystallography - one paper suggested a patentable invention to me in November 1987 and and few months later the guy who had edited the article showed up with provisional patent from the previous May (when he\'d been editing it).

It\'s kind of boutique and the shape may be hard to manufacture or
prove less durable due to stress concentration in the interior angles. also
getting the pattern right is essential. Some sort of pattern assistant is
probably warranted.
