"The truth of these days is not that which really is, but what every man persuades another man to believe" - Michel de Montaigne

In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
In the case of a bow and arrow, when the archer does work on the bow, drawing the string back, some of the chemical energy of the archer's body is transformed into elastic potential energy in the bent limb of the bow. When the string is released, the force between the string and the arrow does work on the arrow. The potential energy in the bow limbs is transformed into the kinetic energy of the arrow as it takes flight.

A Classical View of Quantum Time Crystals - by Georg Engelhardt
When a collection of atoms reaches a sufficiently low temperature, they arrange themselves periodically in space to form a crystal. Since the equations that describe the atoms’ motion do not contain any information that prescribes a crystal lattice, this phase transition isn’t trivial to explain even in its simplest form. Experimental and theoretical studies have revealed many types of classical and quantum phase transitions that lead to spatially ordered states. But there are other possible forms of order beyond that of the atoms’ spatial arrangement. In 2012, Frank Wilczek theorized a novel type of phase transition in which matter spontaneously exhibits time-periodic motion, meaning that it arranges itself periodically in time rather than in space. The resulting phase of matter is called a quantum time crystal.
After realizing that time crystals cannot arise under equilibrium conditions, as Wilczek originally proposed [1], many researchers assumed that time crystals are a genuine nonequilibrium quantum effect. However, by employing large-scale numerical simulations, two independent collaborations led by teams at the University of Cambridge, UK, and at the University of California, Berkeley, have found that certain types of time crystals, known as prethermal, can be described using purely classical equations of motion. Their simulations show that many-body systems of classical spins exhibit all the basic features of quantum time crystals, indicating that prethermal time crystals are a classical effect [2–4]. The finding suggests that a description rooted in classical physics can suffice to describe these time crystals and may suggest ways to create them experimentally.

Bacteria, fungi interact far more often than previously thought
In a novel, broad assessment of bacterial-fungal interactions, researchers using unique bioinformatics found that fungi host a remarkable diversity of bacteria, making bacterial-fungal interactions far more common and diverse than previously known. [...] Of the 702 total fungal isolates examined by the research team, bacterial associates were found in 88 percent—an unexpected detection rate relative to previous, more limited studies.

NIER Effects on Flora & Fauna: A Major Review
A detailed examination —likely the most exhaustive ever attempted— of the environmental effects of non-ionizing radiation has been published in Reviews on Environmental Health.
“Effects of Non-Ionizing Electromagnetic Fields on Flora and Fauna” is in three parts, the last of which was posted today. They are:
- Part 1. Rising Ambient EMF Levels in the Environment
- Part 2. Impacts: How Species Interact with Natural and Man-Made EMF
- Part 3. Exposure Standards, Public Policy, Laws, and Future Directions
Taken together, the three papers run over 200 pages in the journal and include more than 1,000 references.
The authors are Blake Levitt, Henry Lai and Albert Manville. Levitt is a science journalist, based in Connecticut, and the author of Electromagnetic Fields: A Consumer's Guide to the Issues and How To Protect Ourselves, first published in 1995. Lai is a professor emeritus at the University of Washington, Seattle. In the 1990s, he and N.P. Singh were the first to show that ELF (60 Hz) EMFs and RF radiation could lead to DNA breaks. Manville is a lecturer at Johns Hopkins University in Baltimore and, formerly, a wildlife biologist with the U.S. Fish and Wildlife Service.
“We approached it from the biology/environmental ecosystem level, rather than the typical physics and/or human physiology side,” Levitt told Microwave News. She added that they are planning to publish a book on the topic for the lay reader.

Quantum Entanglement Has Now Been Directly Observed at a Larger Macroscopic Scale
While there's nothing to say that quantum entanglement can't happen with macroscopic objects, before now it was thought that the effects weren't noticeable at larger scales – or perhaps that the macroscopic scale was governed by another set of rules. This new research suggests that's not the case. In fact, the same quantum rules apply here, too, and can actually be seen as well. Researchers vibrated the tiny drum membranes using microwave photons and kept them kept in a synchronized state in terms of their position and velocities. Both the first and the second study have been published in Science.

"Corporate Affiliations and Funding of Machine Learning Papers" - Findings from the paper "The Values Encoded in Machine Learning Research" (2021) (discussion)
"Our analysis shows substantive and increasing corporate presence in the most highly-cited papers. In 2008/09, 24% of the top cited papers had corporate affiliated authors, and in 2018/19 this statistic almost tripled, to 71%. Furthermore, we also find a much greater concentration of a few large tech firms, such as Google and Microsoft, with the presence of these "big tech" firms increasing more than fivefold, from 11% to 58%."

No Such Agency
Conspiracy theories assume that there is hidden agency: That somebody actually is in charge and knows what they are doing, even though they might be "evil". What is far more terrifying and realistic: There is little to no agency. Nobody is in charge and nobody knows what they are doing. A combination of chaos, incompetence and confusion is running the show and everything else is in essence just a cargo-cult invented by hairless monkeys that only recently learned how to talk.
Related: When Robert Anton Wilson was asked what the central conspiracy was that we had to look out for, he answered "stupid people".

Abū Mūsā Jābir ibn Ḥayyān (أبو موسى جابر بن حيّان) (c. 806−816)
Abū Mūsā Jābir ibn Ḥayyān is the purported author of an enormous number and variety of works in Arabic, often called the Jabirian corpus. The works that survive today mainly deal with alchemy and chemistry, magic, and Shi'ite religious philosophy. However, the original scope of the corpus covered a wide range of topics ranging from cosmology, astronomy and astrology, over medicine, pharmacology, zoology and botany, to metaphysics, logic, and grammar.
Abū Bakr Muḥammad ibn Zakariyyāʾ al-Rāzī (أبو بكر محمد بن زكرياء الرازي) (864 - 935)
Abū Bakr Muḥammad ibn Zakariyyāʾ al-Rāzī was a Persian physician, philosopher and alchemist, widely considered one of the most important figures in the history of medicine. He also wrote on logic, astronomy and grammar. A comprehensive thinker, al-Razi made fundamental and enduring contributions to various fields, which he recorded in over 200 manuscripts, and is particularly remembered for numerous advances in medicine through his observations and discoveries.

Eureka! The Story of Archimedes' Greatest Discovery is deeply misunderstood
"Archimedes' principle (The buoyant upward force acting on an object is equal to the weight downward force of the displaced fluid) is merely a side-effect of Archimedes true greatest discovery: Great ideas emerge while having a bath. It is not the ideas we should celebrate, but the process that leads to their discovery." - Samim

Nuclear Electromagnetic Pulse (NEMP)
A nuclear electromagnetic pulse ("Nuclear EMP") is a burst of electromagnetic radiation created by a nuclear explosion. The resulting rapidly varying electric and magnetic fields may couple with electrical and electronic systems to produce damaging current and voltage surges. The specific characteristics of a particular nuclear EMP event vary according to a number of factors, the most important of which is the altitude of the detonation.
(N)EMP Effects on Electronics
An energetic EMP can temporarily upset or permanently damage electronic equipment by generating high voltage and high current surges; semiconductor components are particularly at risk. The effects of damage can range from imperceptible to the eye, to devices literally blowing apart.
#Comment: Consider how much modern civilization relies on electronics and how only a hand full of NEMP's can take them all out.
Electromagnetic radiation hazards (RADHAZ or EMR hazards) (via)
Hazards caused by a transmitter/antenna installation that generates electromagnetic radiation in the vicinity of ordnance, personnel, or fueling operations in excess of established safe levels or increases the existing levels to a hazardous level; or a personnel, fueling, or ordnance installation located in an area that is illuminated by electromagnetic radiation at a level that is hazardous to the planned operations or occupancy.
