Hats off, comments on
The Hat and the Spectre – Recent Groundbreaking Discoveries in Mathematics
Math nerds found two wild new shapes, and the comments immediately went off-topic
TLDR: Researchers announced the Spectre, a new shape that fills space in a never-repeating way and answers a question left open by the earlier Hat discovery. The comments instantly stole the spotlight, with one person arguing over the title date and another joking that they came for actual hat news.
Math just got a surprise glow-up: researchers behind the Hat came back with the Spectre, another shape that can cover a flat surface forever without falling into a repeating wallpaper pattern. The big deal here is that the newer shape does it without needing a flipped mirror version, which closes a question the Hat left hanging. In plain English: this is one of those rare math stories where people genuinely get to say, “Wait, they found a new kind of shape trick?” and mean it.
But the real entertainment is in the crowd reaction, where the mood swings from fussy editor energy to full-on dad-joke chaos. One commenter was laser-focused on the title, insisting “(2023) should be added” like the biggest emergency in mathematics was a timestamp. That sparked the kind of tiny-but-very-online metadata drama the internet lives for: not “What is truth?” but “Can we please label this correctly?” Then another commenter swerved the whole conversation into comedy with a line about wanting “recent groundbreaking discoveries in hats” instead. Instantly, the vibe became less elite math lecture and more “someone get Jimmy Kimmel back on the phone.”
So yes, the article is about a major discovery in mathematics, celebrated with museum events, papers, and even a competition for creative tile designs. But in the comments, people are doing what people do best: nitpicking the title, making puns, and reminding everyone that if you put the word Hat in a headline, the internet will absolutely treat it like fashion news first and math news second.
Key Points
- •The article presents the Hat as the first known aperiodic monotile, a shape that tiles the plane only in a non-repeating pattern.
- •It explains that the Hat’s tilings require both reflected and unreflected copies, leaving open a further mathematical question.
- •The article states that the later discovery of the Spectre answered that question by providing a chiral aperiodic monotile that works without reflected copies.
- •David Smith, Joseph Samuel Myers, Craig S. Kaplan, and Chaim Goodman-Strauss are identified as the authors behind both discoveries.
- •The article also covers public engagement around the discoveries, including media coverage, recorded talks, and the Einstein Mad Hat Competitions organized by the National Museum of Mathematics and the United Kingdom Mathematics Trust.
