You Can Only See Wavelengths From 380 to 750 Nanometers ? #short #science #physics

[00:00:01]Cause three, the limits of human senses.

[00:00:06]Your eyes detect photons in a tiny range of wavelengths, 380 to 750 >> [music] >> nanometers. That's less than 1 trillionth of the electromagnetic spectrum.

[00:00:25]So, what we call visible light is just a tiny sliver. There's so much more. It's like we've been reading a single letter in an encyclopedia and thinking we understand the whole book.

[00:00:44]Radio waves, microwaves, infrared, visible, ultraviolet, x-rays, gamma rays, all are the same phenomenon.

[00:00:57]Your eyes see only one octave out of 60.

[00:01:00]And even within that narrow window, your brain isn't showing you wavelengths.

[00:01:06]It's painting qualia. The redness of red doesn't exist in physics. It's a construction of your consciousness, a translation of a 650 nanometer wavelength into subjective experience.

[00:01:23]So, other animals see more reality than we do. We're not at the top.

[00:01:28]>> [music] >> We're just specialized.

[00:01:32]Each species lives in its own sensory universe.

[00:01:36]It's Umwelt.

[00:01:38]The bees' world is painted [music] in ultraviolet patterns we'll never see.

[00:01:42]The snakes' world is a heat map, [music] and we thought our world was the complete one.

[00:01:51]Evolution shaped your senses to help you survive, not to see objective [music] reality. You see colors, not wavelengths. You feel solidity, not [music] electromagnetic repulsion.

[00:02:07]Your brain creates a simplified model of the world.
