#PhysicsFactlet
The human eyes have "only" 3 different colour receptors, so multiple spectra can be perceived as the same colour.
(And this without considering all the ways the signal is processed before you actually "see" it.) #Optics#Colour#Color#Vision

#PhysicsFactlet: The "Ashcroft/Mermin Project"
I will try to (likely very slowly) go through the classic textbook "Solid State Physics" by Ashcroft and Mermin and make one or more animation/visualization per chapter.
This will (hopefully) help people digest the topic and/or be useful to lecturers who are teaching about it. As with all my animations, feel free to use them.
The idea is that the animations are a companion to the book, so I will give only very brief explanations here.
