Pythagoras Was Wrong About Music | Biochar's Potential For Carbon Capture
The Greek philosopher Pythagoras had specific ideas about the mathematical ratios behind music. It turns out that he was wrong. Also, the charcoal-like substance known as biochar packs carbon into a stable form, making it less likely to escape into the atmosphere.
Pythagoras Was Wrong About MusicThe ancient Greek philosopher Pythagoras proposed a mathematical argument for what music sounds best to the ear: According to legend, he said listeners preferred music with chords adhering to perfect mathematical ratios, like 3:2. This concept has persisted in modern Western music, specifically for building harmonies.
But new research out of the University of Cambridge disputes this idea. A set of behavioral experiments with more than 4,000 participants in the US and South Korea found that listeners actually prefer chords with a slightly imperfect mathematical ratio, particularly when played with non-Western instruments.
Tim Revell, deputy US editor of New Scientist joins Ira to talk through this story, as well as other big science stories of the week, including a big change to YouTube’s algorithm, a new battery breakthrough for electric cars, and the Smokehouse Creek Fire in Texas.
Farmers And Environmentalists Alike Are Excited About BiocharIn a former biomass plant in Greenville, wood chips are flowing from hoppers into long tubes about three feet in diameter.
Pat Jones is the president of Clean Maine Carbon, which burns wood in high-temperature, low-oxygen conditions known as pyrolysis. “It starts out as wood” he said. “And as you can see when we come over here what comes out the other end is biochar.”
In the quest for climate solutions, Jones is among the Maine entrepreneurs banking on this charcoal-like substance. They say it can bind up carbon for decades, and improve agricultural soils at the same time.
The end product has high carbon density, and is very stable, so less of the carbon will be released into the atmosphere than if it were left to decompose. So while Jones is making biochar, his business plan is focused on selling carbon credits to corporations.
