# The equivalence principle as a stepping stone from special to general relativity: A Socratic dialog

@article{Drake2006TheEP, title={The equivalence principle as a stepping stone from special to general relativity: A Socratic dialog}, author={Samuel P. Drake}, journal={American Journal of Physics}, year={2006}, volume={74}, pages={22-25} }

We show how students can be led to an understanding of the connection between special relativity and general relativity by considering the time dilation effect of clocks placed on the surface of the Earth. This paper is written as a Socratic dialog between a lecturer and a student.

Was Einstein an Engineer?

Despite being renowned as one of the most abstract thinkers of the 20th century, Einstein was also very interested in the application of ideas, and it could be argued that he was more of an engineer than a physicist, especially in his early career. Expand
