i spent a very enjoyable math binge day learning about waves and what i learned is that waves are extremely fucked up

wifi relies on radio waves! there are international regulations on which parts of the radio spectrum people are allowed to use!! it is *illegal* to emit too many *photons of certain frequencies* because you might *interfere with the photons people are using to download porn*

the range of human hearing is apparently between 20 Hz and 20 kHz. humans can hear sound waves oscillating *twenty thousand times a second*!!

what's the deal with people noticing that everything is vibrations and then deciding that means they should become vegan or collect crystals instead of learning signal processing theory

Note that when neuroscience people talk brainwaves they usually mean the time-domain electric waves in the EEG, not the travelling activation waves (space-domain) like in this awesome picture. But, yeah, there are real waves in the brain of all sizes and speeds!
