National Security Secret
#109. Knowledge is being silently lost online and increasingly difficult to acquire.
Around the middle of the last century, the country faced a turning point. The harnessing of electricity and discovery of radio had created opportunities for all to enjoy. But the Great Depression demonstrated how a price is paid when resources are over-used and human suffering is the cost.When invention and discovery brought the universe into perspective, it happened through radio. Radio is just one part of the electromagnetic spectrum and science showed it like this:
How does this qualify as "dumbed down"?
The wavy lines with changing wavelength aren't shown now. They used to be a standard part of most diagrams to find. Losing those waves doesn't seem significant at first but they provided a hint of future trouble.
At last glance, it looks like knowledge has been gained so science can be more precise when explaining our universe.
That's the exact opposite of what's happened.
What was presented in an intuitive visual form has changed to dry numbers with less context. It makes learning more difficult or confusing. Grasping concepts or abstractions takes longer because more context has to be looked up and memorized prior. It slows down development and education. Even worse, knowledge can slowly be lost while the human race believes they're getting smarter.
Does that sound backward?
Hold onto your microwave - you're about to get a quick science lesson on acoustics (sound waves).
The sound waves humans speak with travel in spreading waves. Stereos, TVs, and public warning systems use the same. Guess what? Our cell can do better than that! They're too small for an ancient speaker and use a buzzing type instead:
A piezoelectric transducer.
They're flat and can produce sound not just in waves. Even those currently installed in cell phones can focus sound closer to a beam which makes it "directional".
How does that apply to the diagram?
The shorter the wavelength for radio, the more it becomes directional (that's also why our microwaves don't kill us outright compared to gamma rays, but that's a much worse post to write). The older diagrams intuitively presented that drawn in waves. It also applies to sound.
The smaller the wavelength of sound, the more directional it becomes (it's why bats use it to hunt, the reason they became weakened, and a fungus killed so many, but that's an easier post to write).
Are you ready for a big announcement? How to produce sound in 3 dimensions for TV or movie theaters was discovered last century. That shouldn't be difficult to believe. There were hints it was on the way, clear signs it would work under certain conditions or venues, and sounded pretty cool. Then formal news about it never arrived.
Developing and testing something like 3D sound requires knowledge about oscillation, resonance, and polarity. Making use of 3D sound requires knowledge of the human mind.
All those things are needed in addition to understanding directional waves before a real product or service publicly arrives.
For better or worse, without regard for public health, and without permission or awareness from the audience a product or service was delivered in stages. It experienced failures or mistakes and had to "start over" more than once. One iteration coincided with "millenials". One or more iterations coincided with a sharp change in reported autism rates.
What's the correlation?
More information will be provided.
