Archimedes is a LaTeX and Markdown editor built from the ground up for the Mac and designed to make mathematical writing fun and easy.

At its core, Archimedes is a fully-featured plain text and Markdown editor. It includes a fast syntax highlighter and provides convenient keyboard shortcuts for common actions, such as inserting images and links. With complete support for Markdown, Archimedes makes formatting and structuring documents elegant and easy.

# BuoyancyIn science,**buoyancy**is an upward force exerted by a fluid that opposes the [weight](https://en.wikipedia.org/wiki/Weight) of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.

In Math Mode, Archimedes lets you write mathematics in a subset of LaTeX. Just enter `$$`

to get started. Over 700 intuitive commands, such as `\sqrt{a^2 + b^2}`

, help you produce stunning mathematical output. Archimedes even autocompletes commands and intelligently matches closing braces, brackets, and parenthesis as you type.

Just getting started with LaTeX? Don't know the code for the *asymptotically equal* symbol? Use your MacBook's trackpad or Magic Trackpad to draw it! Archimedes will recognize the symbol and insert the corresponding code for you.

As you work, a beautifully-typeset live preview of your document is always visible. You can even switch between horizontal or vertical orientation and select a custom theme.

Browse the math library to see all available LaTeX commands and their previews in one place.

Archimedes lets you define macros -- or custom commands -- for the expressions you work with the most. Macros show up in autocompletion results right alongside built-in completions.
