There is a series of Latin and pseudo-Latin phrases used in a scientific context (mostly in the life sciences) describing how and where a study was carried out (sorted by frequency):
- in vitro – in a glass,
- in vivo/ex vivo – in a living organism / not in a living organism,
- in situ – on site,
- in natura – in nature,
- in silico/silicio – in a computer (model),
- in simulacra/simulacris – in a model,
- in papyro – on paper.
I am now looking for a concise analogous phrase to describe that a study was carried out with a mathematical model. I considered and was not happy with the following options so far:
In simulacris – may as well apply to animal models, in vitro models, or other experimental models.
In mente – implies that the entire study was carried out without the help of a computer or even paper.
In silicio – excludes studies or parts of studies that were carried out in the mind or on paper.
In theoria – is more narrow than in simulacra, but still contains qualitative scientific theories or models, respectively.
In mathematica – Does not capture the modelling aspect very well; I might as well be engaging in pure mathematics. Moreover, it sounds as if I forgot to capitalise Mathematica.
In simulacris mathematicis – Fits, but lacks elegance.
