Mathpad is an easy to use text editor for mathematics. You can mix together ordinary text and any mathematical expression. Ideal for math teachers to create quizzes, tests and handouts. Also, you can save the formatted text as an image. With most equation editors you choose a template with the mouse, type a few keystrokes and repeat the process. Mathpad doesn't work this way. Mainly, you just type characers at the keyboard. Most people find this to be easier and faster.

Mathpad has some unusual features. For example, the implementation of standard italics for math symbols is simplified by the "automatic math" specification. In this mode, the ordinary text and math expressions get italicized correctly. Another example - the macros feature allows macros with arguments and is easier to use than more sophisticated macros as in Tex/

In cosmology, dark energy is a hypothetical form of energy which
permeates all of space and has strong negative pressure. According to
the theory of relativity, the effect of such a negative pressure is
qualitatively similar to a force acting in opposition to gravity at
large scales. Invoking such an effect is currently the most popular
method for explaining recent observations that the universe appears to
be expanding at an accelerating rate, as well as accounting for a
significant portion of the missing mass in the universe.

Two proposed forms for dark energy are the cosmological constant, a
constant energy density filling space homogeneously, and quintessence,
a dynamic field whose energy density can vary in time and space.
Distinguishing between the alternatives requires high-precision
measurements of the expansion of the universe to understand how the
speed of the expansion changes over time. The rate of expansion is
parameterized by the cosmological equation of state. Measuring the
equation of state of dark energy is one of the biggest efforts in
observational cosmology today.

Adding a cosmological constant to the standard theory of cosmology
(i.e. the FLRW metric) has led to a model for cosmology known as the
Lambda-CDM model. This model agrees closely with established
cosmological observations.

As NASA reports indicate, 70 percent or more of the universe consists
of dark energy, about which we know next to nothing.

At the beginning of March, 2006 the satellite of China National Space
Administration, DARKSTAR started operations, observing in neutrino the
solar corona.

It results a sensational information that our system also contains
dark energy. This substance is located within the solar surface.

We have placed above cosmological information into our screensaver and you
can view allocation of dark matter in our Solar system!

Rapid-Pi is an add-on for Microsoft Word (and other word processors) that will transform the way you enter mathematical formulae, equations and expressions into documents.

Rapid-Pi was designed with a single purpose in mind - to save you time when editing math in documents. Rapid-Pi's text-based input is a simply faster way to input math.

Most equation editing programs require you to click on toolbar buttons or go through menus in order to insert symbols and expressions. This process is inherently slow and painful. Even simple things like fractions take up too much time - you have to click on the fraction button, then click in the numerator, type the numerator, click in the denominator and type the denominator. Consider how much faster and easier it would be if you could simply type "1/4". That's exactly what you can do with Rapid-Pi.

NOTE: Rapid-Pi is an add-on for your existing word processor application (like Microsoft Word), not a stand-alone program. This means that you will continue to use your favorite word processor, inserting Rapid-Pi equations into your document whenever you need to enter math. Inserting a Rapid-Pi equation is easy - just click on the Rapid-Pi button on Microsoft Word's toolbar (toolbar button is currently only provided for Microsoft Word 2000 and later).

Rapid-Pi supports a large number of mathematical symbols and expressions, including all symbols supported by Microsoft Equation Editor.

If you don't know the keyword for a symbol, you just click on the appropriate toolbar button and Rapid-Pi will insert the text for you (for example, ".a" for lower-case alpha, ".int" for integral, etc). Soon, you'll probably find that you don't need to use the toolbar 90% of time. The toolbar will still be available for the occasions when you need to enter a symbol that you've never used before (or if you forget how to enter a rarely-used symbol).
