How Can We Know If an Asteroid Will Hit Earth?

You’ve no doubt seen this kind of news headline: “Astronomers Say Space Rock May Hit Earth in the Not-Too-Distant Future!” We usually get such warnings about one or two objects every year; the latest iteration concerns an asteroid, 2024 YR4, that is estimated to be more than 50 meters wide. For a while there was… Continue reading How Can We Know If an Asteroid Will Hit Earth?

Mathematics + Symbols = a Surprising × Contentious History

War in Europe is a staple topic in the study of history, but there’s one major conflict most history books won’t teach you: the battle of the equal sign, =. These two parallel lines were, in fact, the source of serious dispute among European mathematicians in the mid-1500s. This dispute is just one of many… Continue reading Mathematics + Symbols = a Surprising × Contentious History

Will AI Ever Understand Language Like Humans?

Large language models (LLMs) are becoming increasingly more impressive at creating human-like text and answering questions, but whether they can understand the meaning of the words they generate is a hotly debated issue. A big challenge is that LLMs are black boxes; they can make predictions and decisions on the order of words, but they… Continue reading Will AI Ever Understand Language Like Humans?

Dimension 126 Contains Strangely Twisted Shapes, Mathematicians Prove

It can be tempting to assume that your intuitions about three-dimensional space carry over to higher-dimensional realms. After all, adding another dimension simply creates a new direction to move around in. It doesn’t change the defining features of space: its endlessness and its uniformity. But different dimensions have decidedly different personalities. In dimensions 8 and… Continue reading Dimension 126 Contains Strangely Twisted Shapes, Mathematicians Prove

To Make Language Models Work Better, Researchers Sidestep Language

Language isn’t always necessary. While it certainly helps in getting across certain ideas, some neuroscientists have argued that many forms of human thought and reasoning don’t require the medium of words and grammar. Sometimes, the argument goes, having to turn ideas into language actually slows down the thought process. Now there’s intriguing evidence that certain… Continue reading To Make Language Models Work Better, Researchers Sidestep Language

Touch, Our Most Complex Sense, Is a Landscape of Cellular Sensors

Genetic technologies soon gave him a way to do so. During the first decade of his studies of neuronal development, Ginty amassed a library of genes specific to different touch neuron types. Around 2007, he began genetically engineering mice in which these genes could be used to control particular populations of touch neurons. In each… Continue reading Touch, Our Most Complex Sense, Is a Landscape of Cellular Sensors
