11.5 OSP Simulations, that were not created with EJS

A large number of OSP Java simulations are present in a group of Launcher packages, structured according to themes, which can be obtained a the OSP homepage.

Many of the packages have been developed as courses. Fig.11.10 shows the typical appearance when opening one of them. This launcher has three directories that can be opened via clicking on the buttons or with the file menu.

The directory Relativity Workshop, that can be called from the list on the bottom, contains a complete course on special and general theory of relativity, subdivided in chapters ordered according to topics. Some of them contains describing text with static pictures, theory and problems, many contain in addition interactive simulations.

The directory About OSP contains details about the authors, about the launcher method, with which many individual files can be combined to a package and about options of the presentation, among them language selection, provide this was enabled by the authors of the simulations.

The directory Programs contains many interactive cosmological simulations from Newtonian mechanics to Kerr and Rain metrics. For a number of simulations version created by the lecture are next to versions, that were produced by students.

The directory Programs has the structure as shown in Fig.11.9 with many sub-directories.

On the right a picture and a short description is shown for a selected simulation. The picture shows light rays, that originate radially from a body in the vicinity of a black hole. Double clicking on the green triangle activates the simulation.

The File menu on top of Fig.11.9 contains options for editing and for exporting individual simulations.

Here you should again look directly on the OSP homepage, where new packages or versions are present.

In addtion the comfortable search function of the home page allows to search for certain topics , levels and intended audiences. Fig.11.12 shows the search tree. The individual selection boxes are each structured into numerous categories. For the topics this is shown in the following section. Search
