I use the keyboard layout EurKey, which is available on KDE Plasma. It's QWERTY but with European special characters on layer 5, i.e. they are accessed by Alt Gr.

Ich sage einfach nur Spreizblatt. Damit weiß typischerweise jeder, was ich meine.

Um das kurz auszuführen: ZFC steht für die Zermelo-Fraenkel-Mengenlehre mit Auswahl-Axiom (C wie Choice). Die Mengenlehre kann mit und ohne Auswahl-Axiom definiert werden und stellt die fundamentalen Grundregeln dar. Daraus können alle Theoreme ("Regeln" der Mathematik) hergeleitet werden.

Typical transition frequencies between two levels of an atom are 10^15Hz. The coupling between atoms and light is on the order of the decay rate at which photons are transmitted, which sits at around 10^6Hz.

I describe the atoms using a so called Lindblad master equation. The atoms are kept in this description, but the light field is eliminated using two assumptions:

  1. The coupling between the two is very weak.
  2. Correlations between the two decay so fast that this can be considered instantaneous.

The later produces white noise.

I work on quantum systems coupled to noisy environments (noisy as in causing random fluctuations). Atoms coupled to a light field are my specialty. Anyway, I just got invited by a predatory journal in the field of acoustics, vibrations and noise?!

Except they know that they would have to cover the apple in a thin metallic layer for it to be observable under an electron microscope :D

Thank god the universe is purely described using linear algebra.

Lovely picture! Either I don't get the meme part or I can't find Saddam.

If you ever find yourself among theoretical physicists and/or astrophysicists and need a conversation starter, just ask about unit systems or unitless/natural measurement systems. There is no other profession that is more obsessed about that topic.

Just to put this here:
