While the typical answer is 33 beats per minute, musician Adam Neely's answer morphs into a great primer on the "perceptual present," a concept widely discussed in both the philosophy of music and of consciousness. Read the rest
The five traditional senses are tied to visible sense organs, but depending on the definition, humans possess dozens of senses, including thermoception (temperature), proprioception (bodily spatial relations), nociception (pain), equilibrioception (balance), and mechanoreception (vibration).

M.C. Escher: Adventures in Perception (1971) is a 20-minute Dutch documentary about the artist and includes scenes of him working in his studio. From Open Culture:
Obsessed with perspective, geometry, and pattern (Escher described tessellation as “a real mania to which I have become addicted”), his images have, by the count of mathematician and Escher scholar Doris Schattschneider, led so far to eleven separate strands of mathematical and scientific research.
The twenty-minute Adventures in Perception, originally commissioned by the Netherlands’ Ministry of Foreign Affairs, offers in its first half a meditation on the mesmerizing, often impossible world Escher had created with his art to date. Its second half captures Escher in the last years of his life, still at work in his Laren, North Holland studio. It even shows him printing one of the three titular serpents, threaded through a set of elaborately interlocking circles, of his very last print Snakes. He never actually finished Snakes, whose patterns would have continued on to the effect of infinity, and even says here of his officially complete works that none succeed, “because it’s the dream I tried for that can’t be realized.”
Water is viscous. With heat, the viscosity drops. And you can hear the difference in its splash.
This video explains the weirdness of the McGurk effect, a perceptual illusion demonstrating that understanding speech is not just about what we hear, but also what we see. You can learn more about the McGurk effect at Yale's Haskins Laboratories dedicated to the science of the spoken and written wordl. (via Imaginary Foundation) Read the rest
I really love the research that they're doing over at Yale's Haskins Laboratories: instead of studying speech perception and production in terms of faithfully replicating alllll of the sounds we make with our mouths, (like the minute clicks, pops, and hisses of consonants), the team is proposing that all we need to understand speech is to track and re-create a few select resonances of the vocal tract. I like to think of speech production in this context as a series of bottles with varying levels of water in them--the mouth is one bottle that changes pitch resonance when you move it to open it or close it, the nasal cavity another, and so on throughout the vocal tract. It ends up sounding like a bunch of complicated melodies that are then combined into a complex micro-tonal harmony, a.k.a., we're all better at perceiving and making music than we think we are!
The examples below break it down into isolated sine-wave patterns that you can combine yourself to build a sentence. What do you think? How easily can you hear words emerge?
