I Simulated Insect Vision and It Got WEIRD

Sobre este vídeo

Here’s what compound eyes really do — and why flies see you in slow motion. A few centuries ago, scientists believed insects saw thousands of tiny, repeated images — like a kaleidoscope of candle flames. But that’s not how compound eyes work. In this episode of Big Ideas from the team behind Deep Look, Niba explores how insects actually see the world — from the structure of ommatidia to motion detection, ultraviolet color vision, and the evolutionary advantage of seeing faster than we do. From ancient trilobites to modern pollinators, this episode dives into the evolution, physics, and neuroscience behind the most common eye type in the animal kingdom. 🧠 Why compound eyes dominate the planet ⚡ How insects see motion in “slow motion” 🌈 What colors insects see that humans can’t 🪰 Why flies are so hard to swat Welcome to Big Ideas — where we zoom out to answer the biggest questions about how animals survive. 👉 Donate to KQED, the public media station that makes Deep Look: https://donate.kqed.org/deeplook SIGN UP for Deep Look’s newsletter, Nature Unseen: https://bit.ly/NatureUnseenSignUp SUBSCRIBE: https://www.youtube.com/@KQEDDeepLook?sub_confirmation=1 ---+ Find a transcript on KQED Science: https://www.kqed.org/science/2000059/what-an-insect-view-really-looks-like ---+ More great Deep Look episodes: There’s No Place Like Home: 4 of Nature’s Savviest Homeowners https://www.youtube.com/watch?v=oNDU6IYH3Eo This Stick Insect Has a Peppermint-Scented Secret Weapon https://www.youtube.com/watch?v=BmPCRIwi0mg 4 of the Deadliest Tiny Hunters We've Ever Filmed https://www.youtube.com/watch?v=HLr0Xleaxb8 ---+ Thank you to our top Patreon supporters ($10+ per month)!
