What Is the Magnetic Constant and Why Does It Matter?

wired.com Rhett Allain 2025-11-02 05:30:00

This means these three values can’t be independent; if you know two of them, you can derive the third. How do physicists deal with this? We define the speed of light as exactly 299,792,458 meters per second. (How do we know it’s exact? Because we define a meter as the distance light travels in 1/299,792,458 of a second.) Then we measure the magnetic constant (μ 0 ) and use that value along with the speed of light to calculate the electric constant (ε 0 ). Maybe that seems like cheating, but to

Image by Getty / Futurism Cancer It's no secret that our efforts to save the planet from the excesses of global trade are failing spectacularly. Our bodies are riddled with manmade compounds, cities are routinely enveloped by massive clouds of noxious smoke, and glaciers are melting faster than ever before.

Stepanov's biggest blunder? The curious case of adjacent difference

news.ycombinator.com Roman Kashitsyn 2025-10-30 16:30:59

The curious case of adjacent difference If you have ever tried using the std::adjacent_difference algorithm in c++, I’m sure it left you puzzled. As the name suggests, this algorithm computes differences between adjacent elements of the input sequence, but it does one more thing: it copies the first element of the input sequence into the output sequence unmodified. The following example demonstrates how to apply the algorithm to delta-compress a postings list of document identifiers that contain

Why wind farms attract so much misinformation and conspiracy theory

When Donald Trump recently claimed, during what was supposed to be a press conference about a European Union trade deal, that wind turbines were a "con job" that drive whales "loco," kill birds and even people, he wasn’t just repeating old myths. He was tapping into a global pattern of conspiracy theories around renewable energy—particularly wind farms. (Trump calls them “windmills”—a climate denier trope.)
