Quantum physicist takes aim at the arrow of time
Scientists and philosophers have argued over the nature of time since ... well, since time immemorial.Does time flow unceasingly in one direction? Is our perception of time merely an illusion? Does each instant exist eternally, a

Researchers have discovered a mechanism to overcome the traditional energy limit (the energy cutoff) in X-ray production by using helium atoms irradiated with intense ultraviolet (UV) lasers. In this process, two quantum-mechanically correlated electrons recombine with an ion simultaneously, releasing their combined energy as a single, higher-energy X-ray photon.

A Pendulum for the Multiverse: David Albert, Hugh Everett, and the Worlds We Never Feel
On my grandfather's porch in North Loup, Nebraska, the ground kept its promises. Summer evenings the floorboards held the day's heat, the corn stood in rows that ran clear to the horizon, and nothing in all that flat immensity so much as trembled. When a teacher first told me the Earth was spinning at close to a thousand miles an hour while racing around the Sun at sixty-seven thousand more, I pressed my bare feet against those boards and waited to feel the ride. The stillness came back like a verdict. Whatever the books claimed, my soles reported a stationary world, and a boy trusts his soles. Every child who has run that experiment has rebuilt, in miniature, the strongest objection the seventeenth century could throw at Copernicus. If the Earth turns, why does a dropped stone land at the foot of the tower and never a few feet to the west? Why does the gale of our orbital speed fail to strip the leaves from the trees? The objection deserved respect because it rested on evidence, on the honest testimony of every human body that had ever stood still. It took Galileo's ship, and then Newton's laws, to explain why that testimony, though honest, was worthless. […] -

A guided map across physics, biology, engineering, and AI—built around a simple idea
Persistence is not generated, but permitted.
Systems don’t fail because they “break.”
They fail because their boundaries were misclassified.
Core structure
state → constraint → resolution → persistenceFrom: - Titanic / Vasa / Challenger
– biological regulation
– AI hallucination & drift
– institutional collapseSame pattern
only admissible states persistThis is the interface.

🧩 “Is #structure the true #reality?”🌐
In the current #Zoomposium, we discuss with #MichaelEsfeld why #reality does not consist of things, but of #structures and #relationships. His moderate ontic #structural realism combines #quantum physics, #metaphysics, and #consciousness.
