As a grad student, Fan Chung figured out a way to prove an important estimate in Ramsey theory. 50 years later, no one has improved it. But as she likes to tell her students: “Do not give up. A problem proves its worth by fighting back." quantamagazine.org/why-the-key-to…
Earlier this year, a 17-year-old high school student named Hannah Cairo solved a 40-year-old mystery about how waves behave, surprising and exciting mathematicians. @KSHartnett reports: quantamagazine.org/at-17-hannah-c…
As weird as it sounds, infinity comes in many shapes and sizes. Mathematicians study these different notions of infinity to understand the limits of mathematical logic. Tune in to this week’s episode of The Quanta Podcast. Apple: podcasts.apple.com/us/podcast/is-… Spotify:…
We are once again sending a big call-out for problem set submissions! Share some fun math directly with our participants in prisons across the US and Canada! More info here: forms.gle/FAGNuikuTqdfkN…
Older people now make up 5x as much of the prison population as they did three decades ago. Turning prisons into “makeshift nursing homes” is one of the nation’s most wasteful, morally bankrupt experiments to date. And it certainly doesn’t make our communities safer.
What’s the most efficient way to pack spheres into a space? This math question has useful applications in cryptography, engineering and long-distance communication. A recent paper has created enthusiasm for an unorthodox way to solve it. quantamagazine.org/new-sphere-pac…
The secret geometry that underlies how wave functions evolve went undetected for decades. Explore the hidden landscapes that are now coming into view: quantamagazine.org/first-map-made…
Across the US, 113 million adults have an immediate family member who has ever been to prison or jail. Mass incarceration has far-reaching consequences that don't stop at the prison gates.
From living matter to molecules to elementary particles, the world is made of “chiral” objects that differ from their reflected forms. @savagitsky reports: quantamagazine.org/how-the-univer…

[Erdős 1964]: The following are equivalent: (1) If there is a set Φ of entire functions such that {f(z) : f ∈ Φ} is countable for every z ∈ ℂ, then Φ is countable. (2) The continuum hypothesis is false.
In mathematics, different dimensions have decidedly different personalities. quantamagazine.org/dimension-126-…
The US has the highest incarceration rate of any independent democracy on Earth, making it a leader in mass incarceration. Far too many people are locked up in the “land of the free.”
How many teachers does it take to do a subtraction problem? One, because it only takes one teacher to make a difference. Happy Teacher Appreciation Week!
Prison labor is usually mandatory and often unpaid. This May Day, we're thinking of the incarcerated workers who are exploited every single day to keep prisons running.
Building large language models can feel more like growing a tomato plant than building a machine, says Martin Wattenberg, a language model researcher: “You watered it, you weeded around it, but how on earth does that tomato plant work?” quantamagazine.org/why-language-m…
A positive integer is called *idoneal* if it cannot be written as ab+bc+ca for some integers 0<a<b<c. Theorem. The number of idoneal integers is either 65,66, or 67. en.wikipedia.org/wiki/Idoneal_n…
