A film of turpentine subjected to soundwaves. Taken by Hans Jenny using Schlieren photography.
Hans Jenny was the kind of Renaissance man I love: physician, fine artist, pianist, philosopher, historian, and empirical researcher. He is nicknamed the "father of cymatics," the study of wave phenomena. Between 1958 and his death in 1972, Jenny conducted a wide range of experiments documenting the effects of sound and energy on various media. This work is collected in the remarkable historical document Cymatics . He places his work in the context of the Greek philosophers who proposed systems of thought based on mathematical order and the relationship of sounds, musical tones, and words. What I love best about his work is that you can feel his wonderment in every chapter and every image (like this soap bubble that became a polyhedron when subjected to sound) . Originally two volumes (the second was published posthumously), Jenny's work on periodicity is now collected in a coffee table book-sized tome full of his photos and essays. His work has captured the imagination of physicists, musicians, New Agers, and anyone who enjoys reading the works of visionary polymaths. Check it out!

The great science purge, they’ll call it one day. Donald Trump is closing science offices throughout the federal government. ‘As of June, around 85 percent of all scientific posts in the federal government, including an official scientific advisor to the President, were left unfilled,’ write the editors of I F***ing Love Science blog in an […]
With enough practice and commitment, anyone can be a visual artist. But without the right instruction, that time spent honing your skills could seem like an eternity. If you really want to see where your talent can take you, you need sound fundamentals – and no matter what discipline or genre you lean toward, the […]
Theoretically, there’s never been an easier time for marketers. The ubiquity of social media means a good word – or a good brand – can spread like wildfire with very little effort. But as limitless as the internet is, there’s a lot of competition and noise to contend with. And the vast graveyard of failed […]

If so, here’s 10 headphones and earbuds that break out of the Apple mode with a return to quality and wearability. Klipsch R5 Bluetooth Neckband […]
