Most knowledge is about driving action through practice - which can't be effectively prescribed from above, only cultivated from beneath. Most efforts by leading global private/public "knowledge ecosystem" institutions ("Science Inc.", etc.) are political / commercial power-plays - disguised, corrupted and confused.

The ideas were not good, but ideas that nobody else had
"Nick was a remarkable idea man. The ideas were usually not good, but they were really remarkable in that they were the kind of ideas that nobody else had. Nick really was a genius in a very important sense -- he often invented things that required two new ideas simultaneously, which is something that normally, hardly anyone ever does." - Herbert York describing Nicholas Christofilos

Earth's Natural Radio: Strange sounds at VLF frequencies and below - NVARC Presentation by Philip J Erickson (W1PJE) (May 2022)
"I will provide an overview of natural emissions at very low electromagnetic frequencies in the VLF (3 - 30 kHz) and ULF (300 Hz - 3 kHz) ranges. These radio emissions are generated by physical phenomena, such as lightning discharges or interactions with plasma in the ionosphere, and in some cases are global in nature. They are also very interesting because their RF frequencies are primarily within human hearing range (although they are not acoustic waves!), and so heterodyne receiver architectures are not needed - making both receiver and transmitter design quite simple.
I will cover natural emissions, including audio samples, and describe what they tell us about the ionosphere and magnetosphere, including whistlers, chorus hiss, sferics, and more. Also covered will be human signals in this frequency range, such as power line harmonics and VLF communications signals used by almost every government for information transfer to submerged vessels. Some information will be provided as well on the challenges of receiving and transmitting signals in this range within your backyard, including the "Dreamer's Band" amateur frequencies below 9 kHz and the new "EbNaut" digital mode for this frequency range."
About Philip J Erickson
I am an associate director and head of the Atmospheric and Geospace Sciences group at Haystack Observatory, operated by Massachusetts Institute of Technology (MIT). Haystack is located approximately 42 km as the crow flies from the main MIT campus on a 1300 acre parcel overlapping the towns of Westford, Groton, and Tyngsboro, MA (grid FN42go). Since the late 1950s, Haystack has conducted frontier remote sensing research into the properties of the near-Earth space environment, including the ionosphere, neutral atmosphere, overlying plasmasphere, and the magnetosphere that surrounds our planet.I am a member of Nashoba Valley Amateur Radio Club (NVARC), a physical as well as spectral neighbor of Haystack. Outreach programs and activities are ongoing between Haystack and NVARC; see the NVARC page for details. I am also a member of the HamSCI citizen science initiative.

Inverse-square law - a persistent rumor
"In science, an inverse-square law is any scientific law stating that a specified physical quantity is inversely proportional to the square of the distance from the source of that physical quantity. The fundamental cause for this can be understood as geometric dilution corresponding to point-source radiation into three-dimensional space."

Atoms in Two Dimensions Could Mark a Strange New State of Matter, Physicists Say
Qubits can spin in two dimensions, instead of just one, and it could be revolutionary for quantum computing. A different pattern of laser pulses could make quantum computers way more stable.
New research uses a Fibonacci-inspired, non-repeating sequence to keep qubits spinning.
This creates a quasicrystal effect, with support in two dimensions instead of just one.

The Most Famous Paradox in Physics Nears Its End
In a landmark series of calculations, physicists have proved that black holes can shed information, which seems impossible by definition. The work appears to resolve a paradox that Stephen Hawking first described five decades ago. Growing evidence supports what physicists have long suspected: In some way or other, space-time itself seems to fall apart at a black hole, implying that space-time is not the root level of reality, but an emergent structure from something deeper.
At Long Last, Mathematical Proof That Black Holes Are Stable
The solutions to Einstein’s equations that describe a spinning black hole won’t blow up, even when poked or prodded.

The breakdown of the classical scientific model continues:
Does Quantum Mechanics Reveal That Life Is But a Dream?
"Life is a joke, and the joke is on you if you believe otherwise."
Study provides first evidence of non-random mutations in DNA
"This goes against one of the key assumptions of the theory of evolution."
Roboticists discover alternative physics
"There are alternative ways to describe the universe and it is quite possible that our choices aren't perfect."
