# Buoyancy

In 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.

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.

Reviews

★★★★★  So Convenient! This is the perfect editor for those who enjoy the simplicity of Markdown, but need LaTeX for scientific and mathematical writing. The ability to draw symbols and have them magically turn into escape codes will save you hours of time!
- App Store review

★★★★★  I use this app every day - highly recommended. I have recommended this to colleagues and students, even those who are not experienced with TeX, and they are always amazed that, for a very modest price, they can load one app and be productive right from the start. Another big positive for me is that Archimedes' rendered PDF is quite good: clean, modern and readable.
