I swear, at the rate we're going, we'll have scopes that can probe literal daylight by the time I'm 40...
Well my eyeball can probe daylight and "measure it" - i.e., put it into a visual frame for my brain ... but perhaps what it's seeing is being disturbed by itself and what I see isn't really what's out there - outside my brain. 
OK I'm stopping myself before somebody else does.
you mean we carry two ultra high frequency spectrum analyzers around in our head in the form of eyeballs ? and two low frequency spectrum analyzers in the form of ears ? and our skin can sense infrared ? and we even have a built in signal generator that can do arbitrary signals. it's called a mouth. and its all connected via electrical interfaces to a massive computer and data storage system called a brain.
dammit. why do we need all that complicated testgear then !
one day, i took a small dose of LSD-25, half a dose,
the walls were breathing in and out...
like this, but faster:
like this fast, but real:
i wanted to know why i see that...
i stared at the mirror in my bathroom, firmly looked into my eyes,
and noticed that both eyes were moving synchronized with a Horizontal LFO near 1Hz-5Hz,
like a Synth,
and i guessed that was causing the Walls to Breath,
was impressive to think how "the machine works."
like this, but less crazy
