> Most of your examples are software!
Most of my examples are from computational chemistry, which is software, but (historically) written by chemists.
As one of those chemists (at least before my current work), I feel somewhat qualified to comment on my field and whether it always names things seriously or not.
But if you look around, fun terms are everywhere in chemistry or chemistry-adjacent fields. For example, PALM and STORM (from fluorescence microscopy) were almost certainly chosen because they were easy to remember.
> Also SHAKE and RATTLE describe the motion-simulation in the algorithm.
Not really. SHAKE and RATTLE are bond constraint algorithms to avoid simulating the fast degrees of freedom, typically in solvent.
In molecular dynamics, your time step is effectively set by the fastest degree of freedom (there’s a relationship with the Nyquist theorem here), so it pays to freeze out the vibrations of the O-H bonds in water when you’re simulating a larger system. SHAKE and RATTLE effectively freeze the bond and angle distances near equilibrium while allowing some relaxation.
The rest of the degrees of freedom are typically integrated with a larger time step using a method appropriate for the simulation ensemble (eg: one of the Verlet integrators, a Langevin integrator, etc).
> Acronyms are abbreviations for meaningful names.
Acronyms like XPS, EPR, NMR, etc are like that: dry, short, and meaningful.
But there are a lot that were chosen because they were entertaining to the authors or because they are easy to remember. Even in a technical field, marketing matters.
