LA: Quoties ego coquo (servum non habeo) saepe cucinam relinquere non possum ut ne cibaria periclitetur - placenta compressa (italica lingva "pizza") valde nigra fieri potest si in fornace sine tutela perpetua relicta sit. Sed tempus sperandi mihi odiosus est et quamobrem occulatione ephemeri requiro. Interdum ephemeridas lego, interdum omnes earum jam legi et alterna optioni requiro - et quamobrem ludum japonicum "sudoku" solvo (inflectio quam "genu", credo).
Ludus matematicus est, ubi chartam cum cellulis LXIV habemus de IX quadra composta, unusquisque cum III * III cellulis. In omnibus columnis, omnibus ordinibus et omnibus quadris numeri I ad IX distribuendi sunt, sed auctores jam aliquot numeri indicaverunt, id quod restrictiones solvatoribus ludi imponet. Exempli gratia: hic modo numerus V in loco vacuo licitus est

Alium exemplum:

In ordine I, positione V, modo numerus IV licitus est. IX Illicitus est quia jam IX in eadem columna stat, et V illicitus est quia in eadem quadra de III * III cellulis. Bone, quid in positione IV scribere? Numerum V jam utimus, et V etiamnum illicitus est, igitur IX scribimus. Et positioni IX modo optio V restat:

Tamen solutio immediata non semper exstat. Se inter plures optiones nescio quam eligere, in omnes cellulis vacuis numeros chirographo minusculo et in alia colore scribo. Hic numerus IV in positioni V certus (et licitus) erat, sed nescimus quid in positionibus IV et IX scribere:

Forsitan nunc restrictiones occultas extant quae mihi permitterent novas cellulas cum numeris implere, sed ars sudokua solvanda valde complicata est, et hic non omnis stropha enumeratura est. Modo unum exemplum:
Sudoku-4.jpg
Putamus in positionibus V et IX modo numeros V et IX licites esse. Istae duae cellulae igitur occupant duas ex tria optionium quae in positone IV licitae erant, et modo restat numerus IV, qui igitur certus est:

Programmata computralibus existant qua sudokua solvent, et ego egomet iamdudum tabulam calculatoriam (Excel) construxi, quae strophes diversam per grados intermediarios applicavit, ita ut supra descripsi. Sed - homo vel macchina - interdum situationes occorent ubi solutiones immediatae non sunt - ne quidem restrictiones 'occultas' observante inter cellulas cum solutionibus alternativis. Facte semper solutio unica in sudoku bonum existat, et itaque situatio (ut videtur) sine solutio modo situatio est ubi stropha idonea non jam inventa sit. Tamen saepe simplicius est experimentum facere. In cellula (potius cellula cum solum duas optionibus, aut cellula quae una ex solum dua cellula sit quae quendam numerum capere posset) conjectionem indicatur, et opera solvendi continuatur. Si contradictionem inveniemus, conjunctio falsa erat et alterna possibilitas igitur vera essere debet. Et ego opino quod ars conjectiones jucundas agnoscendi summum opus solvatoribus constituit.
EN: 'Nuff said about sudokus. I have also read some popular science texts and one about a Westgothic law text, which now has appeared in a Russian translation, but that will have to wait for later. I could however not resist from mentioning that while I composed the Latin text above I was watching TV made by a fringe phenomena, namely people who believe in the idea that extraterrestrial beings not only have visited the Earth, but also restructured the human genome .. and maybe even 'terraformed' the Earth to make it suitable for us. The idea of terraforming has come up in connection with Mars, which by some individuals is seen as the place we (all?) should emigrate to if (or rather when) we have destroyed the environment here ourselves or will see it destroyed by an asteroid soon. The idea is that by deliberately infusing the Martian atmosphere by greenhouse gases and liberating the frozen water at the poles we could make the climate there somewhat more clement. The reality is that even after an impact the size of the one that eradicated all dinosaurs (minus the birds) 65 mio. years ago it would be easier to re-terraform the Earth than to do the same work at Mars. Besides the Earth has been successively terraformed throughout its history, but the main events took place several
billions of years ago: first when water was reintroduced to the Earth by a swath of waterbearing meteorites after its first scorching 2-300.000.0000 years, next when blue-green algae started producing an extremely poisonous gas named oxygen ... at least most of the organisms who lived back then found it extremely unpleasant and they had to retreat to the most inhospitable locations on the planet, like inside rocks or in hot lakes. Everything that has happened since then is of minor importance and has absolutely nothing to do with us ... except of course the changes in the nature which we are causing. But we can't blame extraterrestrials for those.
