LaTeX and `plain' TeX are the core components of the widely used open-source (free) typesetting system, which is freely available for all computer platforms (Linux/Unix, Microsoft, MacOS, and others). Roughly speaking, `plain' TeX is the original system of low-level code, while LaTeX is a comprehensive system of macro-packages which greatly facilitates the use of TeX code and hence makes the process of typesetting much more straight forward.

Over the years LaTeX and `plain' TeX have been greatly extended by an extremely active world-wide open-source community, into the world's leading typesetting system for getting maths, poems, plays, graphics, music, ... onto paper, PS, PDF, HTML, XML etc. There is an active TeX Users Group in most countries, and several national and international TeX conferences are held each year (see the TUG homepage for conference information). Visit the Latex-Project website for information regarding on-going software development.

The name TeX: Nowadays, owing to the many extensions which have been developed, the name `TeX' is now used generically as a collective term denoting the wide range of related and free high-quality typesetting software tools & components, for example: TeX, LaTeX, Metafont, Metapost, Babel, BibTeX, ConTeXt, PSTricks, AMSTeX, PDFTeX, LuaTeX, XeTeX, and more, all of which come with any standard TeX installation (see details of the DVD below). All the TeX-related software is freely available from web archives and on DVD (see installation below).

History: TeX (now known as `plain' TeX) was initially developed in 1978 by the Stanford professor of computing Donald Knuth (1938--). LaTeX, the associated system of TeX macro packages, was developed in 1985 by Leslie Lamport (1941--). Both of these computer scientists are detailed in the book Out of their minds--the lives and discoveries of 15 great computer scientists by DE Shasha and CA Lazere (1995) [publ: Copernicus, Springer-Verlag]. Note that one of the reasons the TeX system has been so successful lies in the fact that it is a programming language in its own right---a typesetting language.

Some interesting historical overviews are as follows:
--- A brief history of TeX. In: Taylor P (1996) Computer typesetting or electronic publishing? New trends in scientific publishing.
--- Reutenauer A (2008) A brief history of TeX: II
--- Doob M (1990). TeX and the single CPU: I (Notices Amer. Math. Soc., vol 37; p 270--273)
--- Doob M (1991). TeX and the single CPU: II (Notices Amer. Math. Soc., vol 38; p 1243--1246)
Some further historical details can be found in the Wikipedia articles on TeX, and LaTeX.

Usage: Once you have a working TeX system installed on your computer (see details of the `Installation DVD' below), documents are then typeset by first creating a file (the tex file) containing tex commands and of course words, diagrams, pictures etc. You then use one of the TeX engines (either `plain' TeX itself, or more usually either LaTeX, pdfLaTeX, XeLaTeX, LuaLaTeX) to generate the output file (say, a PDF file) which can then be viewed in the usual way. Other document formats, eg HTML, DVI, PS etc are generated in a similar fashion using the appropriate conversion `tool' or `TeX' engine.

Although pdfLaTeX is currently the TeX engine used by most people, new `engines' are being developed and upgraded. For example, the XeTeX and XeLaTeX engines significantly extend pdfLaTeX by offering native support to Unicode, and allowing easy use of modern font formats (eg, True Type and Open Type). LuaTeX, which is currently at a fairly early stage of development, further extends flexibility by incorporating the programming language Lua.

Introductory information: Before deciding whether to obtain a copy of the latest installation DVD (known as the TeX Collection ---see details on the `Installation DVD' below), those curious about the TeX system may wish to read some general articles, for example, LaTeX--an introduction (by Unwalla 2006), or What is TeX?, or Starting out with TeX, or The levels of TeX, or Begining LaTeX (by Peter Flynn 2011).
Some relevant `overview' TeX articles have appeared in the Notices of the American Mathematical Society, as follows:
--- Downes M (Mar 2002) TeX and LaTeX2e
--- Hefferson J and Berry K (Mar 2009) The TeX family in 2008 [6.9MB]
--- Gratzer G (Jan 2009) Whats new in LaTeX? I: Breaking free
--- Gratzer G (May 2009) Whats new in LaTeX? II: TeX implementations, evolution or revolution
--- Gratzer G (Sep 2009) Whats new in LaTeX? III: Formatting references
--- Gratzer G (June/July 2011) Whats new in LaTeX? IV: WYSIWIG LaTeX

Installation DVD: Contains complete implementations of TeX and associated systems for Linux/Unix (TeXLive), MS Windows (proTeXt), and MacOS (MacTex), as well as a copy of the extensive CTAN archive of TeX software. Although all of the TeX systems are freely available for download, they are large systems (1-2GB) and are most conveniently installed from this annual DVD (known as the TeX Collection). The latest version of the TeX Collection DVD (July 2011) is available from the TUG Store for about US$50. Alternatively, it is probably cheaper to join your local TeX Users Group, since the annual DVD is a free membership benefit. For example, membership of the UK TeX Users Group is only about £10.

Documentation: A good list of TeX-related documentation is at TeX resources on the web, and also at the Latex-Project website for guides and books on TeX. Of course the TeX Users Group homepage and the FAQ and the TeX Catalogue and LaTeX reference manual are also good places to browse. See also the directory /texmf-dist/doc/latex/base/ for in depth information on all things to do with the LaTeX system and packages.

Journals: The TeX User's Group publishes two English language journals, namely, TUGboat (contents) and PracTeX both of which are freely available on the web.

Users Groups: Most countries have a strong TeX Users Group, many of which produce a journal which often carries English language articles.

Conferences: The main regular international conferences are those of TUG, EuroTeX, BachoTeX, ConTeXt. Note that most national TeX Users Groups also hold their own annual conferences.

Pulfrich effect

The Pulfrich effect (discovered by the physicist Carl Pulfrich 1858-1927) is a most unusual visual phenomenon with interesting mathematical, vision physiology, and clinical applications, which is occasionally exploited for making 3D television programs (a memorable Dr Who episode was made this way--see New Scientist article (1993); 13 November, p.23---as well as an episode of `3rd rock from the sun'). The Pulfrich website is the main location for all things Pulfrich. The 1922 paper in which he describes the Pulfrich-effect is as follows:

Origami

During the last 30 years or so the Japanese art of paper folding, known as Origami, has increasingly been attracting the attention of mathematicians and engineers, who have now formalised origami mathematically by establishing the so-called seven Huzita axioms of folding (see Lang's website). For example, using origami one can solve equations, trisect angles, generate lengths representing rational and irrational numbers (see Lang 2003), and create representations of fractal systems (Dacorogna 2010). Indeed, a forthcoming space telescope is being designed with origami principles in mind (see Dacorogna 2010).

William Freeman Daniell (1817-1865)

WF Daniell was an English army surgeon and botanist. He was instrumental in bringing Calabar beans from West Africa to Edinburgh pharmacologists who then discovered their physostigmine content. Edinburgh physicians then went on to show that physostigmine was the first anticholinergic. Daniell collected plant specimens in Africa, Jamaica, China, and several plants have been named after him. His specimens are housed in the Natural History Museum herbarium and also in the herbarium at Kew Gardens (London). See also online biography
