How to use / include Scientific / Math ... Equation, Formula, rules, laws, fonts, graphics, etc in your web site ?
I'm REQUESTING to PhysOrg.com website AUTHORITY to let us(/writers) use the font named "Chryſanþi
" or other (open-source) math font (see below, or, one of my next posting) which can be used for expressing many types of formula, equation, math, logic, statistics, calculas, algebra, etc. If we have one of those UCS/Unicode
fonts, then special math characters, superscript, subscript, etc can be used on the posting by using the " &#nnnnn; " format, which are part of ISO 10646
universal character set (UCS) and "Unicode". Right now (as of May 11, 2005) they are not allowing any math fonts. At least safe characters, letters, numbers should be allowed to use, by using html decimal coding ("&#nnnn;"), which are part of (older) ISO 8859-1
("Latin-1"/"western") character set. It is a very essential requirement for a website like this. If they enable those features, or, already exist, it will be mentioned below, see next postings.
Currently, there is a limitation on how many picture files you can use in your posting. (Probably 10 picture files). But if, PhysOrg.com itself hosted all these small PNG picture files (each math charcter is only 200 bytes), then we can build/express our own equation. As the file sizes are tiny, it should not be any problem to handle, or, they can/should allow writers to include/use unlimited external or their own site's PNG picture files, at least. If they change this limitation, it will be mentioned in one of my next posting

Representing equation/formula through the use/implementation/linking of small transparent graphic files
are easier, and will be displayable/supported in almost all type of web browser. But you may not find all of your character, or, not in right alignment/places. If PhysOrg.com itself provides lots of pre-created math character PNG/GIF
files, then we can link/use them with with great success, safely.
A PNG file with a single math symbol/Character is not even 200 bytes, compared to a single math character GIF file, which can be 23KBytes. So, PNGs are way better than the GIFs.
Representing equation/formula can be done also through the use of UCS font
like "Chryſanþi", "Code2000
" or other Unicode/UCS/ISO 10646 fonts
which supports Math, Greek, Roman & all other Symbols. This is the new, future standard
Or, it can be represented by using html decimal
formatted code ("&#nnn;" or, "&#nnnn;"), for a limited number of character/symbol, if (older) ISO 8859-1 / WGL compatible font is used. But, in this way at least most basic math charcters can be displayed in all browser. Special math fonts
(Unicode/UCS) can provide all type of math characters, so we should use open-source/license fee free fonts.
Math charcters can be displayed by using "LATEX
" (a modified version of Tex) coding approach as well. One of the LATEX type of solution is to convert your Math by using Latex conversion to a GIF picture file, like ("latex2html"). And resultant files will display on any graphics browser.
If you like, some type of free, open-source implemetation, which is very superior/better than using those small graphic files, and/or, TrueType
fonts, etc, then we have many choices also.
Among them, ... download/install a "plug-in" soft and/or a "Unicode/UCS font" for displaying MathML
coding type (which is actually a variant of XML code) of equation/formula, developed by the World Wide Web Consortium, The W3C. This mathode can represent/cover almost all type of math/science equation/formula with super great clarity. "The W3C" have a free MathML editor called Amaya. Amaya can also serve as a Web Browser to view MathML documents, as well as ordinary basic HTML.
Math equ can be displayed by using CSS
I'll not go into commercial fee based solutions.
And very important thing is ... when you're using these codes ... BEFORE
you finally SUBMIT
/add your posting/writings into the forum/web page, PLEASE PREVIEW
them first (use "Preview" button/feature), if the characters/letters are really getting represented/alligned in the right way.
My this posting is a result of inspiration from "Good Elf" (PhysOrg.com's member).
Below are some sites which can allow/let us post scientific or mathemetical equation, formula, graphics, font, etc on the web page :http://us.metamath.org/symbols/symbols.html

The mission of the Scientific and Technical Information Exchange (STIX) font creation project is the preparation of a comprehensive set of fonts that serve the scientific and engineering community in the process from manuscript creation through final publication, both in electronic and print formats. Toward this purpose, the STIX fonts will be made available, under royalty-free license, to anyone, including publishers, software developers, scientists, students, and the general public.

TtH - TtH translates Plain TeX or Latex into a near equivalent in HTML. It is extremely fast and completely portable. It produces web documents that are compact and fast-viewing. TtH translates and displays mathematical expressions using the symbol fonts which are included in the 4+ versions of Netscape and Internet Explorer. TtH cannot display inline matrices and over dots. Inline fractions do not display well either. Overall, however, TtH is one of the best technologies available in the summer of 2000. The example file winedt.tex was converted into winedt.html (5KB) using TtH. There are some minor problems with vertical and horizontal alignment, but the mathematics is quite readable.http://pdg.cecm.sfu.ca/openmath/

Fonts for MathML.http://www.w3.org/Math/
MathML 2.0 - a W3C Recommendation was released on 21 Feb 2001. A product of the W3C Math working group, MathML(Mathematical Markup Language) is a low-level specification for describing mathematics as a basis for machine to machine communication. It provides a much needed foundation for the inclusion of mathematical expressions in Web pages. Many implementations of MathML are available (browsers and authoring tools), many of which are open source software. Go to the MathML Software list ( http://www.w3.org/Math/implementations.html
) for descriptions and pointers, or read the Implementation and Interoperability report (http://www.w3.org/Math/iandi). There is a good chance that your browser already supports MathML (possibly with the addition of a plug-in). You can try this test page to find out. If you want to put your mathematics on-line this way, read how to put mathematics on the Web with MathML document (http://www.w3.org/Math/XSL).http://netlib.org/cephes/
Cephes is a C library that provides numerous mathematical functions including support for the complex variable types that will be in the new ANSI C standard, C99. Among the numerous functions available are: the elementary functions (log, sin, cos, exp, etc), gamma, psi, dilogarithm, Airy, Bessel, hypergeometric, Struve, complete and incomplete elliptic functions, Planck radiation, Fresnel integrals, probability integrals and their inverses (Gaussian, Poisson, F, Chi-square, binomial, Kolmogorv-Smirnov arithmetic on polynomials, rationals, etc), and so on. You can get it with precisions from single, double, long double (80, 96 or 128 bit), q-class (384-bit). Source code is available, as well as precompiled binaries for Linux, Windows and MSDOS. http://www.gnu.org/software/gsl/
