Open Source Physics

Open source physics is a way for scientists to share and work on physics projects with other people around the world. It's like working on a project together, but instead of being in the same place, you can work on it together online. To do this, scientists can use open source software, which is free software that anyone can download and use to help create and share their projects. Once the project is finished, it can be shared with others who can use it to continue their research. Open source physics makes it easier for scientists to collaborate and learn from each other.
