Thijs Hogenkamp's bachelor thesis project in physics concerns the analogies (and disanalogies) between spacetime curvature and optical lensing that led Sir Roger Penrose to developing his first ...

In the lead-up to his singularity theorem, Roger Penrose was inspired by an analogy between Ricci Φ_00 scalar and Weyl Ψ_0 scalar dominated spacetime curvature and anastigmatic and astigmatic optical ...

This interplay could generate the kind of entropy that resolves itself by accident, potentially catalyzing the singularity many are quietly hoping for. The Quantum Singularity Is Unpredictable ...

Finite-time singularity ````{tab-item} Julia :sync ... Thus the corresponding IVP has more than one solution. The following standard theorem gives us a condition that is easy to check and guarantees ...

The singularity of Schwarzschild time slices at the bifurcation sphere is well-known today, but understanding its causal structure took over four decades [46–49]. Given this singularity, it is not ...

The seven decades of "artificial intelligence" have been marked by exaggerated promises, surprising developments and ...

Abstract: After a review of the general aspects of the classical electromagnetic theory several “equivalence” theorems are established and illustrated with a number of examples from the diffraction ...
