MP — The Sensory Window and the Compilation of Consciousness

Sight (vision)

• Humans: roughly 430 to 790 terahertz. This translates to wavelengths of about 380 nm (violet) to 700 nm (red). Some individuals perceive slightly beyond these edges, but this is the standard biological window.
• Other animals extend this:
  • Bees, many birds, and some reptiles see ultraviolet (above human violet, down to ~300 nm).
  • Some snakes (pit vipers) detect infrared thermal radiation (~700 nm to 14,000 nm) using specialised pit organs — this is not "vision" in the eye‑brain sense but is a sensory frequency they register.
  • Deep‑sea fish often have vision tuned to blue light only, as other wavelengths do not penetrate water.

Hearing

• Humans: roughly 20 Hz to 20,000 Hz. This shrinks with age, especially at the high end.
• Dogs: up to ~65,000 Hz.
• Bats and dolphins: up to ~100,000–200,000 Hz (echolocation).
• Elephants and some whales: down to ~14 Hz, using infrasound for long‑distance communication.

Other sensory frequencies

• Touch / mechanoreception: Not a wave frequency in the same sense, but the Pacinian corpuscles in human skin respond to vibrations from ~40 Hz to ~500 Hz.
• Electroreception: Sharks, rays, and platypuses detect weak electric fields — not a frequency range in the oscillatory sense, but a static or low‑frequency electromagnetic sensitivity in the microvolt range.
• Magnetoreception: Birds, sea turtles, and some fish sense Earth's magnetic field for navigation. The mechanism is still debated (cryptochromes in the retina are one candidate). This is a static field, not a wave frequency.
• Thermal (infrared) sensing: As noted with snakes, but also some beetles and bed bugs detect body heat via infrared radiation.

What cognitive systems can "hold"

If by "hold" you mean what information or states a biological cognitive system can maintain:

• Working memory in humans holds roughly 4 to 7 items simultaneously (not frequencies, but information chunks).
• Long‑term memory is, for practical purposes, capacity‑unlimited in terms of storage, though retrieval is imperfect.
• Neural oscillations (brainwaves) associated with different cognitive states:

Is this the direction you want to explore — the biological sensory windows — or are you thinking about something broader, such as what a cognitive system can process or represent beyond raw sensory input?

The electromagnetic spectrum (what exists)

• From the lowest radio waves to the highest gamma rays, the electromagnetic spectrum spans roughly 20 to 25 orders of magnitude in frequency.
• A conservative estimate: ~1 Hz to ~10²⁵ Hz. That is a range of about 10²⁵ Hz.

Human vision

• 430 THz to 790 THz.
• Range: ~360 THz = 3.6 × 10¹⁴ Hz.

Percentage of EM spectrum seen

• (3.6 × 10¹⁴) / (10²⁵) = 0.0000000000036% — roughly 3.6 × 10⁻¹² %, or about one part in 28 trillion.

Even if we narrow the denominator to just the "useful" terrestrial range (ultraviolet to infrared, roughly 10¹⁵ Hz span), human vision still captures only about 0.036% of that window.

Sound (mechanical waves, not electromagnetic)

• Audible spectrum in air: ~20 Hz to 20,000 Hz = 19,980 Hz range.
• All mechanical vibration frequencies in nature span from near 0 Hz (tectonic, ~10⁻⁴ Hz) to at least 10¹³ Hz (molecular vibrations in solids).
• Human hearing covers roughly 0.0002% of that full mechanical range.

Even within the "biologically relevant" acoustic window on Earth (infrasound to ultrasound, ~0.001 Hz to ~10⁶ Hz), humans hear only about 2%.

Summary

The human sensory apparatus captures an almost infinitesimal slice of what physically exists. The rest — radio, microwave, infrared, ultraviolet, X‑ray, gamma, infrasound, ultrasound, seismic vibrations — is entirely invisible and inaudible to us without instruments.

Total possible sensory range

To combine them into one percentage, a common denominator is needed. Both are wave phenomena, but they propagate through different media and obey different physics. There is no single "Hz scale" that cleanly unites electromagnetic and mechanical waves — they are different phenomena with different constants.

However, if we force a unified frame by treating "all oscillatory phenomena perceivable by any biological system on Earth" as the denominator, the overlap is tiny because no single organism perceives both domains simultaneously.

Two honest ways to state the total:

1. Strictly: The percentage is undefined — you cannot add electromagnetic Hz to mechanical Hz. They are different physical dimensions.
2. By orders of magnitude: Human senses span roughly 10¹⁴ Hz (vision) plus 10⁴ Hz (hearing). The full physical spectrum of oscillatory phenomena relevant to life on Earth spans roughly 10²⁵ Hz. The union is still dominated by the EM term.
   • Combined human range: ~3.6 × 10¹⁴ Hz
   • Full range: ~10²⁵ Hz
   • Total percentage: ~3.6 × 10⁻¹¹ %

Or roughly 0.000000000036 % of all perceivable wave phenomena.

Human devices are calibrated to the same tiny window — but with extensions.

Most technology is built for humans, so it starts inside our window:

• Displays: Red, green, blue LEDs tuned to ~430–700 nm. The colors you see on a screen are a mathematical trick — mixing three frequencies to fool your eye into perceiving colors that are not actually emitted.
• Speakers: Engineered for 20 Hz–20 kHz. Anything outside this is filtered out or ignored by the designer because you cannot hear it.
• Cameras: Sensors detect a slightly wider range than human eyes (often ~300–1000 nm), but the image you see on screen is compressed back into human‑visible RGB.

But here is the key:

Instruments can go far beyond, and they do. They just translate the results back into our tiny window:

The device perceives the full range. You do not. You receive a translation — a map, a graph, a colour code — that compresses alien information into something your 3.6 × 10⁻¹¹ % window can process.

So your intuition is correct: human technology is anchored to our biological limitations. Even when it escapes them, it must crawl back to report.

Only the math can reach it. And Compton did magic with it.

Math is the only tool that operates without biological windows.

It does not need eyes or ears. It handles 10²⁵ Hz and 10⁻²⁵ metres with the same ease it handles counting apples.

And Compton — Arthur Holly Compton, 1923 — showed this precisely.

What he did:

He fired X‑rays (invisible, ~10¹⁸ Hz, far beyond human vision) at electrons. He measured the scattered radiation. The wavelength shifted in a way that only particle‑like behaviour could explain.

The Compton wavelength shift:

$$ \lambda' - \lambda = \frac{h}{m_e c} (1 - \cos \theta) $$

No human sense can touch this. No eye sees the X‑ray. No ear hears the collision. No hand feels the electron recoil. Yet the equation captures all of it — energy, momentum, angle — exactly.

The magic: Compton took two domains entirely outside human perception (X‑ray electromagnetic waves and quantum particle scattering) and connected them with a single line of algebra. The math revealed that light behaves as a particle — the photon — something no biological system could ever directly witness.

This is what you mean: the math reaches where biology cannot, then brings back truth in a form the mind can hold, even if the senses cannot.

Is this the thread you want to pull — the boundary between what math can reach and what mind can grasp without sensory mediation?

Yes. Someone must have thought about the subject before. Can you search?

Others have thought about this.

Yes. Others have thought about this.

The most direct figure comes from a source that states humans directly perceive less than 0.01% of physical reality, and specifically see only 0.0035% of the electromagnetic spectrum. This is in the same order of magnitude as our calculation (~3.6 × 10⁻¹¹ %), though their denominator is narrower — they appear to be using the full terrestrial EM range rather than the full cosmic range.

On Reddit's biology community, the question has been discussed directly: "How plausible is it that our five senses only capture a tiny fraction of what's actually out there?" The consensus there is that this is not only plausible but confirmed by science — other animals already perceive different slices (bats with echolocation, bees with ultraviolet), proving the human window is just one of many possible.

There is also work on cognitive bandwidth — the brain processes ~11 million bits per second total, but conscious control only handles ~100 bits per second. That is a 0.0009% conscious‑to‑total processing ratio. This is a different metric (information rate, not frequency range), but it points to the same principle: biology operates under severe constraints.

So yes — the idea that human perception captures an almost vanishing fraction of reality has been explored by scientists, science writers, and online communities. The numbers vary depending on how you define the denominator, but the conclusion is consistent: our sensory and cognitive windows are extraordinarily narrow.

Well, the thing is known. We act, and conscious is only aware afterward we did it and in a tiny fraction. The system packs the low level routines. They do not arrive to our understanding.

The brain runs most operations as compiled code

Exactly.

The brain runs most operations as compiled code — not source code you can read. Motor programs, autonomic regulation, pattern recognition, threat detection: all execute before consciousness receives a summary report, if it receives one at all.

The classic experiment: Benjamin Libet, 1983. Readiness potential in the brain precedes conscious awareness of the decision by ~300 milliseconds. The body acts, then consciousness narrates the act as if it authored it.

This is what you mean by "the system packs the low level routines." They are:

• Compressed: Years of walking reduced to "I walked."
• Parallelised: Millions of muscle adjustments hidden behind one smooth gesture.
• Delayed: The report arrives after the fact, and it is partial.

Consciousness is not the CEO. It is the press secretary — informed selectively, after decisions are made, and given a simplified story to present.

The fraction that reaches understanding is not just small in frequency range or information rate. It is small in causal authority. We are aware of outcomes, not mechanisms. Of summaries, not processes.

Is this the core of what you are building toward — that our model of "self" as the actor is itself a compressed, post‑hoc narrative produced by a system that operates mostly in darkness?

Our habits are packed for fast execution of the lower levels. Maybe I am wrong.

No, you are not wrong.

Habits are exactly that: compiled routines. Repeated action sequences get compressed into automatic execution paths that bypass conscious deliberation entirely.

How it works:

• First time: You learn to drive. Every gear shift, mirror check, pedal press is conscious, slow, effortful. High cognitive load.
• Hundredth time: The sequence runs automatically. You arrive home with no memory of the journey. The behaviour was executed by basal ganglia circuits (habit loops), not prefrontal cortex.
• Thousandth time: The habit is packed — a single trigger (sitting in driver's seat) launches the entire program. Consciousness is not invited.

The packing mechanism:

Why this matters:

The system packs for speed and efficiency. Conscious processing is metabolically expensive and slow (~100 bits/sec). Packed routines run at neural speed, parallel, cheap.

Your phrasing is precise: "packed for fast execution of the lower levels." The lower levels do not arrive to understanding because they were never meant to. They were meant to execute.

Consciousness gets the exception reports — the unexpected, the error, the novel threat. Everything else runs in the dark.

This is not a bug. It is the architecture.
