This thesis deals with essentially four different topics within general relativity: pedagogical techniques for illustrating curved spacetime, inertial forces, gyroscope precession and optical geometry. Concerning the pedagogical techniques, I investigate two distinctly different methods, the dual and the absolute method.Contents:1. Introduction2. An introduction to Einstein's gravity3. Making illustrations4. Making models5. Spacetime visualization6. Inertial forces7. Gyroscope precession8. Optical geometry9. Conclusion and outlookComments on the research papers:10.
