Quantum Picturalism (quantuminpictures.org)
Quantum ideas are often seen as intimidating, which can discourage people from exploring them. We make quantum education accessible by breaking down complex concepts into simple, visual learning experiences.

The cat that wouldn't die (aeon.co)
In 1935, the Austrian physicist Erwin Schrödinger published a rather critical three-part review of what he called the ‘present situation’ in the relatively new theory of quantum mechanics.

Why do electrons not fall into the nucleus? (libretexts.org)
The picture of electrons "orbiting" the nucleus like planets around the sun remains an enduring one, not only in popular images of the atom but also in the minds of many of us who know better.

Looking for a Hidden Determinism (lambdaway.fr)
We consider a complex spacetime framework, using which we propose to recover the results of relativistic and quantum theories, in a purely geometric manner, without appealing to any objective indeterminism of nature.

Why even physicists still don't understand quantum theory 100 years on (nature.com)
Quantum mechanics depicts a counter-intuitive reality in which the act of observation influences what is observed — and few can agree on what that means.

Moiré Than Meets the Eye: Uncovering the Quantum Potential of Phasons (newscenter.lbl.gov)
Researchers have discovered that phasons, low-temperature quasiparticles found in crystal lattices, enable interlayer excitons to move at very low temperatures, when motion should stop.

Quantum Milestones, 1964: John Stewart Bell Rings in New Era of Quantum Theory (2022) (physics.aps.org)
In 1964, Bell showed that quantum physics predicts correlations that violate certain inequalities. The work implied that quantum mechanics is not compatible with locality, even if there were “hidden variables” not accounted for in quantum theory.

Opposing arrows of time can theoretically emerge from certain quantum systems (surrey.ac.uk)
What if time is not as fixed as we thought? Imagine that instead of flowing in one direction – from past to future – time could flow forward or backward due to processes taking place at the quantum level. This is the thought-provoking discovery made by researchers at the University of Surrey, as a new study reveals that opposing arrows of time can theoretically emerge from certain quantum systems.

How Hans Bethe stumbled upon perfect quantum theories (quantamagazine.org)
By 1928, quantum physicists seemed poised to unravel matter’s final secrets. The German researcher Walter Gordon had applied the emerging theory of quantum mechanics to the hydrogen atom, the universe’s simplest atom, and worked out exactly how it behaved. A mastery of all atoms seemed sure to follow.
