Are quantum jumps instantaneous?

In quantum physics, mathematically discontinuous changes – or jumps – between quantum states are popularly referred to as quantum leaps (remember the TV series). As to whether quantum leaps are instantaneous (zero time) or not – as well as random (without any harbinger) – is an open question in physics. This article below recaps additional… Continue reading Are quantum jumps instantaneous?

Life and the physics of having a moon

So, today I’m celebrating the Moon. The ancient mythology and modern physics of its stabilizing influence. Both the Moon’s natural prominence in the earthly sky and its regular cycle of phases as seen from Earth have provided cultural references and influences for human societies and cultures since time immemorial. After enjoying the full moon for… Continue reading Life and the physics of having a moon

A force-less physics?

[“Quantum foundations” series] Force-less physics? No, I do NOT mean that the language of forces (electromagnetism, strong, weak, gravity) does not apply to our everyday experience or to physical descriptions. But only to a point, yes, as maybe counterproductive to deeper understanding. To getting beyond the Standard Model [7]. To understanding how the wave function is… Continue reading A force-less physics?

Quest for room temperature superconductivity

[“Quest” series] This is a topic which I’ve followed for decades. A holy grail of physics: room temperature superconductivity. The physics of Cooper pairs: what makes two electrons pair up when their charge actually makes them repel each other? SciTechDaily > “Breakthrough in Understanding the Physics of High-Temperature Superconductivity” by Helmholtz-Zentrum Dresden-Rossendorf (May 12, 2020).… Continue reading Quest for room temperature superconductivity

Sisyphean hierarchy

In the chapter “Beyond this horizon,” Sean Carroll discusses two related problems involving properties of empty space. Before discussing the vacuum energy problem, he profiles the so-called hierarchy problem in the cosmic energy scale. It’s about the effects of virtual particles. The energy scale that characterizes the weak interactions (the Higgs field value, 246 GeV)… Continue reading Sisyphean hierarchy
