A group of physicists say they've proved that quantum mechanics can be explained without quantum mechanics. I asked ChatGPT, Grok, and Claude what they think about the paper.

A droplet “walking” on a vibrating fluid can mimic quantum physics, forming diffraction patterns just like electrons in the Kapitza-Dirac effect. A rare, visible model of wave-particle duality, letting us watch quantum-like behavior in the macroscopic world.

As a droplet touches a liquid surface it bounces gently, kept afloat momentarily by a thin air cushion. As the air dissipates the droplet comes in contact with the liquid. The droplet undergoes a multi-step coalescence journey: with each interaction, it merges and reduces in size, transitioning into a smaller droplet, until it eventually fully merges with the liquid below.

Harvard physicist Jacob Barandes returns with a groundbreaking insight that could reshape quantum theory. By questioning a single hidden assumption, Jacob bridges the gap between classical probability and quantum mechanics. This ‘mathematical accident’ challenges the foundations of Bell’s Theorem, dissolves the measurement problem, and opens a path to a realist interpretation of quantum physics. This episode is a rigorous journey through stochastic processes, non-locality, and the future of theoretical physics.

Why quantum theory could have a fractal structure: explained in 83 minutes. The notion of true quantum nonlocality is absurd. In the latest episode of the Quantum Foundations Podcast, Prof Tim Palmer from the University of Oxford suggests that there is a hidden assumption in standard quantum mechanics, and dropping it will save us from this absurdity. Namely, the reality of counterfactuals: the physics of what could have happened but did not. Inspired by chaos theory and the fractal structure widespread in atmospheric physics, Palmer has developed a new underlying structure for quantum theory, with radical implications for our fundamental principles of quantum physics; the limits of quantum computation; and perhaps even the search for quantum gravity.

Physicist Yakir Aharonov argues that the standard story of quantum mechanics is wrong, proposing a time-symmetric “two-state vector” view in which reality is defined by wavefunctions from both past and future. He explains weak measurements (information without collapse), nonlocal dynamics behind interference, and phenomena like the “quantum Cheshire Cat.” Aharonov recounts the birth of the Aharonov–Bohm effect, why gauge potentials mislead about locality, and how pre and post-selection restore causal insight without determinism. He shares memories of Bohm, Heisenberg, and Feynman, touches on gravitational and non-Abelian AB analogs, and lays out why a clear narrative—not just math—is essential to understanding quantum theory.

Physicists are still working on how to make general relativity and quantum mechanics consistent. But there's one problem where they are confident they've made the two theories work together: how many bits of information can you store in a black hole?

A homemade castor oil and cayenne pepper salve combined with DMSO might be the best one two punch for pain relief I've ever used. The recipe: 1 cup castor oil, 1 tablespoon cayenne pepper powder. Heat in a double boiler for 5 to 10 minutes, stirring occasionally. The goal is to infuse the castor oil with capsaicin (the active compound in cayenne) without overheating it. Strain, cool, and store in a sealed jar. A few things worth knowing: Capsaicin works by binding to TRPV1 receptors and depleting Substance P, the chemical that signals pain to your brain. That's the science behind why it actually works, not just feels warm. Castor oil is loaded with ricinoleic acid, which has its own anti-inflammatory effect and helps drive the cayenne deeper into tissue. Layer DMSO on top after the salve absorbs and the relief reaches deeper. Just make sure your skin is clean first since DMSO carries whatever is on the surface into your body. Store away from light and heat. Capsaicin breaks down with UV exposure.

Quantum locking, also known as flux pinning, is a fascinating phenomenon that occurs when a superconductor becomes trapped within a magnetic field. This effect was first observed in the 1950s and has since been studied extensively by scientists and physicists.
