Merge
[edit]Ab initio calculations is a stub which is used on only one page, wavelet, and then in a rather vague way. Merge into this disambiguation page which contains almost as much information on the scientific use of the term seems the best solution. "Ab initio calculations" normally refers to the quantum chemistry ab initio quantum chemistry methods, but that is not quite correct for the usage on wavelet, although it is helpful to have it on the disambig page for readers coming from wavelet.
- Support merge as above. --Bduke 23:29, 18 March 2007 (UTC)
- Ab initio is also used when referring to recognition of new genes. Ab initio recognition of genes attempts to predict where in the genome genes will be found i.e GENSCAN using features such as CpG islands and STS (sequence tagged sites) therefore it is possibly not best to just have a marged page.. disambig page is a good idea with linked separate pages refering to each use of the phrase —The preceding unsigned comment was added by 82.24.118.196 (talk • contribs).
- I agree with merging ab initio and ab initio calculations. Xueyamin 19:22, 27 June 2007 (UTC)
- But where to keep the information of Ab initio calculations if they're to merge? The Ab initio article will be too full of information as a DAB page if all the information from the AIC article are merged into the DAB. --Deryck C. 08:53, 10 August 2007 (UTC)
- There really is not a lot of information there. It could certainly be added to the DAB page. This has been around as a merge proposal for a long time. Can we just do it? --Bduke 10:29, 10 August 2007 (UTC)
I have done the merge as there has been no disagreement. --Bduke 23:06, 14 September 2007 (UTC)
Wiktionary
[edit]I know little about Wiktionary, but I have pasted this page as it was, so anyone who wants to can add the info, which doesn't belong on a dab, to Wiktionary.
The Latin term ab initio means from the beginning and is used in several contexts:
- when describing literature: told from the beginning as opposed to in medias res (meaning starting in the middle of the story)
- as a legal term: refers to something being the case from the start or from the instant of the act, rather than from when the court declared it so. A judicial declaration of the invalidity of a marriage ab initio is a nullity.
- in science: A calculation is said to be "ab initio" (or "from first principles") if it relies on basic and established laws of nature without additional assumptions or special models.
- For example, an ab initio calculation of the properties of liquid water might start with the properties of the constituent hydrogen and oxygen atoms and the laws of electrodynamics. From these basics, the properties of isolated individual water molecules would be derived, followed by computations of the interactions of larger and larger groups of water molecules, until the bulk properties of water had been determined.
- in chemistry: an abbreviation referring to ab initio quantum chemistry methods
- in biophysics: a method for the prediction of protein structures in protein folding
- in aviation: The very first stage of flight training.
- as part of some educational qualifications: foreign languages may be taken ab initio - for beginners. Incidentally, ab initio is the name given to the two-year language programme offered in the International Baccalaureate programme. Students who have transferred from one school to another, which don't offer the same language classes, make take an ab initio form of language -- obtaining three credits (approximately three school years of a language) during the two year IB period. This as compared to level B which assumes some level of proficiency.
- in computing: Ab Initio is an extract, transform, load tool used to manipulate data.
- in bioinformatics: a term used to define methods for making predictions about biological features using only a computational model without extrinsic comparison to existing data. In this context, it may be sometimes interchangeable with the Latin term de novo.

- I have been trying to fix some disambiguation links to this page, i think a separate page for ab initio in lowercase with only the latin meaning in other context would make things simpler. in light of miss Boleyn's multiple definitions above, should another page be created for the latin phrase or the current one cleared away from a disambig page.--Theo10011 (talk) 20:36, 5 February 2010 (UTC)
