What is Eculator?

Eculator is primarily a growing collection of searchable and categorized calculators for a large number of physics equations. Equations can be browsed via categories, searched by name (in the text box at top) or searched by the entities they contain via Advanced Search. Each calculator is a part of an equation specific module which also has a corresponding graph plotter and an explanation or a derivation. There is also a Solve Problem tool, which is organized in a way to ease your task of finding the solution to a numerical physics problem. The capability of this tool will increase with time as Eculator grows in the number of formula modules and its algorithms are improved.
