Shortest path algorithms sit at the heart of modern graph theory and many of the systems that move people, data, and goods around the world. After nearly seventy years of relying on the same classic ...

Complexity: a trait that attracts some and deters others. In the classroom, it can feel intimidating or unnecessary. In conversation, however, it makes for surprises that add interest to your day, ...

There is a new sorting algorithm a deterministic O(m log2/3 n)-time algorithm for single-source shortest paths (SSSP) on directed graphs with real non-negative edge weights in the comparison-addition ...

The original version of this story appeared in Quanta Magazine. One July afternoon in 2024, Ryan Williams set out to prove himself wrong. Two months had passed since he’d hit upon a startling ...

It all used to be better, you know. The sun shone, cool winds caressed amber cornfields, everyone got all the Christmas presents they asked for, and real-time strategy was the dish of the day—the ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

If there is one thing New Yorkers can agree on, it’s that “the rent is too damn high.” There are, of course, a number of factors contributing to skyrocketing rents in New York City: a lack of ...

WE LOVE GARLIC! We eat it every day, all year in our cooking! So garlic harvest time is a time to CELEBRATE at WILLOWS GREEN PERMACULTURE! I'm going to get right in there, barefoot in the dirt, among ...

One July afternoon in 2024, Ryan Williams set out to prove himself wrong. Two months had passed since he’d hit upon a startling discovery about the relationship between time and memory in computing.

Quantum computing isn’t just some sci-fi concept anymore. It’s not theoretical. It’s not niche. It’s here—and it’s poised to gut the foundations of modern software development in ways few engineers ...

The original version of this story appeared in Quanta Magazine. Computer scientists often deal with abstract problems that are hard to comprehend, but an exciting new algorithm matters to anyone who ...
