LaTeX and `plain' TeX are the core components of the widely used opensource (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 lowlevel code, while LaTeX is a comprehensive system of macropackages 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 worldwide opensource 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). All TeXrelated software is freely available from web archives and on DVD (see the `Installation' section below). For information regarding ongoing software development see the LatexProject website.
Recent development: 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 for Unicode, and allowing easy use of modern font formats (eg, True Type and Open Type). LuaTeX and LuaLaTeX further extend flexibility by incorporating the programming language Lua.
The name TeX: Nowadays, owing to the many extensions which have been developed, the name `TeX' is used generically as a collective term denoting the wide range of related and free highquality 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.
Usage: Once you have a working TeX system installed on your computer (see the `Installation' section 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.
History: The original TeX system (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 mindsthe lives and discoveries of 15 great computer scientists by DE Shasha and CA Lazere (1995) [publ: Copernicus, SpringerVerlag]. Note that TeX is a programming language in its own righta 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 270273)
 Doob M (1991). TeX and the single CPU: II (Notices Amer. Math. Soc., vol 38; p 12431246)
Some further historical details can be found in the Wikipedia articles on
TeX, and
LaTeX.
Introductory information:
Before deciding whether to install a TeX system (see the `Installation' section below) you may wish to read some general articles on the subject; for example,
LaTeXan 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 interesting `overview' TeX articles have appeared in the journal
Notices of the American Mathematical Society, as follows:

Installation: TeX systems can be installed either from the DVD, or by online download from the internet (see below).
 DVD (TeX Collection): 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 (12GB) and are most conveniently installed from this annual DVD (known as the TeX Collection). The latest version of the TeX Collection DVD (2015) 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.
 online download: See Marc van Dongen's useful documentation for installing LaTeX on MS Windows (chapter 17) and Unix/Linux (chapter 18) platforms.
 Debian platform and TeXLive: If installing TeX on a Debian platform see (TeXLive & Debian)
 MS Windows and MiKTeX:
For MS Windows platforms a particularly convenient and simple `entrylevel' approach is to download the `basic' MiKTeX installer which, when you run it, installs a small MiKTeX system (offering just the pdfLaTeX engine).
Once MiKTeX is installed, you will need to download and install an editor/environment GUI (for example, TeXworks), which will allow you to easily write/edit TeX files and generate PDF output. The TeXworks editor is an excellent choice since it also automatically coordinates the realtime downloading of any missing packages or files you require for a document.
For tweaking MS Windows 7 (eg enabling filename extensions etc) see Stan Brown's Windows 7 tips & tweaks
Documentation:
A good list of TeXrelated documentation is at
TeX resources on the web, and also at the
LatexProject 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 /texmfdist/doc/latex/base/ for in depth information on all things to do with the LaTeX system and packages.

Pulfrich effect (my articles on the Pulfrich effect)
The Pulfrich effect (discovered by the physicist Carl Pulfrich 18581927) 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 waysee New Scientist article (1993); 13 November, p.23as 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 Pulfricheffect is as follows:

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 socalled 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).
For an introduction to the extraordinary world of modern origami see the two video lectures by Lang and by Erik Demaine.

William Freeman Daniell (18171865) (my articles on Daniell)
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 herbarium of the Natural History Museum (London) and also in the herbarium at Kew Botanic Gardens (London). See also online biography
