doors materializing from the wilderness leading to rooms.
this is been in my train of thought for a lot of years.
what’s a good metaphor?
What is the present?
it really is short.
400 ms seems to be the grammar systems scale.
that’s almost half a second. slow.
we all are music folks in our ways. You can do a lot in 400ms.
n400. an example of the point is the decision whether you like a marketable product or not.
do you go yuck or Yum?
that’s the moment you are aware of it to yourself in words.
but you can be aware of it before words.
n170 things are a lot tighter. its preverbal.
but you know.
but once you’re under 50ms, there’s not much time for anything. I forget what happens under the speed but I have Notes. notes happen there. 1000ms/50ms = 20 “somethings” per second.
can fast musician play 20 notes per second with control?
it’s humanly possible. you can switch around in that timespace even though it feels like flow. “the muse”.
can a person gaming or watching a movie notice 60 fps vs 20 fps? oh yes. 60 fps is hyper reality. realer than real. so we’re aware at 50ms.
but then lower : the lowest i know of is 2ms. that’s absolute cellular fusion discernment level where a direction change is blurred.
I don’t remember the modality anymore. visual? acoustic? just the timing.
and the absolute limit for on off discernment is 1ms increments.
you can’t discern ramping up or down underneath a 1ms granularity.
there’s a blur at 2ms for changes.
and the initial off the chart blast from surprise change doesnt really settle fully until 5ms making 5ms the practical lower limit for both kinds of minimal changes: metronomic i’d call it vs change. (texture tone maybe rod bleaching recovery or octopus cell tuning-a-guitar string interstitial beats? i don’t remember)
these are cellular level that’s all i remember.
5ms practical lowest absolute for a single modality on a single smallest task of barely perceptible change.
40ms is a great choice of time as the under 50ms range is the range of nearly magical machinery things imo.
