episode What Percentage of Reality Are We Missing? cover

Beskrivelse

Humans see just 0.0035% of the electromagnetic spectrum and hear only 0.14% of existing sound frequencies. This episode explores the shocking narrowness of our sensory window—from pigeons navigating by infrasound they can hear from hundreds of miles away, to mantis shrimp perceiving colors we literally cannot imagine. We trace how the history of science is really a history of building tools to detect what our senses evolved to ignore, and what the concept of "umwelt" teaches us about the limits of our reality.

How Homing Pigeons Still Beat Modern Tech

Long after telegraphs, radios, and satellites, homing pigeons kept delivering messages — and in some places, they still do. This episode unpacks how these birds navigate using the sun, Earth’s magnetic field, and even the planet’s low-frequency hum. We trace their military history from antiquity through WWII, where 54,000 pigeons served the US Army Signal Corps alone, and into the present day — including the Belgian military’s pigeon program that ran until 2017. You’ll hear about Cher Ami, who saved 194 soldiers despite being shot through the chest, and Joe, whose 20-minute flight prevented a friendly-fire bombing that would have killed over a thousand troops. We also explain why pigeons are still the best option in flood-prone regions of India, and what their navigation system reveals about animal intelligence.
