### The Quantum Mystery of Wigner's Friend

/
In this Insight I will introduce the quantum mystery called Wigner's friend'' using Healey's version [1] of Frauchiger and Renner's (FR's) version [2]…

### The Unreasonable Effectiveness of the Popescu-Rohrlich Correlations

/
In this Insight, I will show how the Popescu-Rohrlich (superquantum) correlations provide an unreasonable advantage in a particular "quantum guessing game''…

### Spectral Standard Model and String Compactifications

/
The Connes-Lott-Chamseddine-Barrett model is the observation that the standard model of particle physics -- as a classical action functional,…

### Tools to Enrich our Quantum Mechanics Interpretations Discourse

/
IntroductionMany times, we encounter ourselves tangled into some Quantum Mechanics (QM) interpretations debates. Unfortunately, the standard…

### Examples of Prequantum Field Theories III: Chern-Simons-type Theories

/
After having constructed gauge fields and higher gauge fields in the previous article by systems of ##L_\infty##-algebroid-valued…

### Does the Heisenberg Uncertainty Principle Imply Energy Nonconservation?

/
The short answer is: no, there's no violation.The longer answer can be this: Given the probabilistic aspect of quantum theory, what do we mean now,…

### Some Useful Integrals In Quantum Field Theory

/
In my paper on renormalisation I mentioned what most who have studied calculations in Quantum Field Theory find, its rather complicated and mind numbing.…

### Some Sins in Physics Didactics

/
Introduction There are many sins in physics didactics. Usually they occur, because teachers, professors, textbook or popular-science-book writers, etc.…
