During cosmic inflation, the universe's volume doubles only about 260 times. Not much, but still, if this happens during an amazingly short time duration Δt, it would be an amazingly fast process.…

A young fisherman in a distant past looks across the sea and ponders: "What an unimaginably big stretch of water!" He has no idea where it ends or even if it ends. But he knows one thing: over time…

This monument is situated just opposite Sudanlage 6, which housed world famous lineage of Institute of Plant Nutrition which was once headed by Professor Dr  Justus von Liebig, in Giessen,…

A long time ago (≈1975) I was involved in establishing a world standard for the measurement of the Optical Transfer Function (OTF). It is better known as its modulus, the Modulation Transfer Function…

Being still in the middle of a rather long vacation (now in the Italian eastern alps), my blogging power is limited. So today I will just offer you some thoughts on the recent measurements of a…

Being still confined in a rather long vacation (now in the Italian eastern alps), my blogging power is limited. I will just offer you some thoughts on a fundamental parameter of the Standard Model…

Welcome to my first blog entry ever! That the Big Bang is the start of the universe, the mysterious “point of creation”, is stated often still today, even by prominent physicists. It is also not true…

The redefiner Ɽt can be mimicked by a trail of infinitesimal unitary transforms. Each subsequent trail element has eigenvectors that differ from those of its predecessor. These eigenvectors are also…

W bosons have been thoroughly studied at the Tevatron collider. Discovered by the UA1 experiment at the CERN SppS proton-antiproton collider in 1984, these particles have since been produced also in…

A new type of operator is required. Why? Because unitary transformations cannot move subspaces of a Hilbert space. They cannot move their own eigenvectors. Since their eigenfunctions span the whole…
