Physicists may have uncovered a surprising new clue that string theory—the idea that the universe is built from unimaginably tiny vibrating strings—could be more than just a mathematical fantasy.

Fifty-eight years after it first appeared, string theory remains the most popular candidate for the “theory of everything,” the unified mathematical framework for all matter and forces in the universe ...

Biological systems are notoriously tough to model, especially when it comes to figuring out the axons, neurons, blood vessels, and other structural components of gray matter, or the tissue that makes ...

A Philadelphia charter school is building its own college. Students at the Philadelphia Performing Arts Charter School, a K-12 facility of about 2,500 with campuses in South Philadelphia and Center ...

For more than a century, scientists have wondered why physical structures like blood vessels, neurons, tree branches, and other biological networks look the way they do. The prevailing theory held ...

In 1980, Stephen Hawking gave his first lecture as Lucasian Professor at the University of Cambridge. The lecture was called “Is the end in sight for theoretical physics?” Hawking, who later became my ...

When you’re getting into web development, you’ll hear a lot about Python and JavaScript. They’re both super popular, but they do different things and have their own quirks. It’s not really about which ...

Thinking about learning Python? It’s a great choice, honestly. Python is used everywhere these days, from websites to smart computers. And guess what? You don’t need to spend a fortune to get good at ...

Killing spiders is the easiest way to get your hands on a lot of string quickly. They’re noisy, so you’ll know their location easily, although we’ve found that they spawn most often in dark caves and ...

A concise collection of core JavaScript concepts including variables, data types, conditionals, loops, functions, callbacks, hoisting, objects, and arrays — with clear examples for quick learning and ...
