1. Open Workbench: MS Project Alternative.
This tool looks really polished. It can be a good project management software.

2. FreeMind: mind-mapping software
This software makes a graphical presentation of concepts and their relationship. Sometimes, the presentation is referred to as a knowledge map. A knowledge map can show elaboration of types. For example, if we want to talk about differential equations, we will find that there are many types of differential equation. Starting from ordinary and partial differential equations, we can further elaborate that ordinary differential equations consists of the first-order and the higher-order differential equations. They can also be classified as linear and non-linear. They can also be discussed by methods for solving differential equations. A knowledge map can give us a big and quick overview of a complex concept to make it easy to organize our idea for a certain concept.
It is also used for brainstorming as discussed here.
