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.

Teaching the gravitational redshift: lessons from the history and philosophy of physics
The equivalence principle and the notion of an ideal clock running independently of acceleration suggest that clocks are unaffected by gravity. The apparent contradiction with the gravitationalExpand
Teaching the Equivalence Principle through a Combination of Real-Life Experiments and Computer Simulations
The need of transforming scientific knowledge to material suitable for teaching school students is a constant challenge for the educational community. Although it has been more than a century sinceExpand
CHIRAL FIELD IDEAS FOR A THEORY OF MATTER IDEAS DE CAMPO QUIRAL PARA UNA TEORÍA DE LA MATERIA
In this paper, a chiral approach is used for developing a unied theory of electromagnetic and gravityelds. The photons which satisfy Maxwell's equations for an electromagnetic wave are taken as theExpand
Relativistic Effects on Clocks Aboard GPS Satellites
Consider a clock aboard a satellite orbiting the Earth, such as a Global Positioning System (GPS) transmitter. There are two major relativistic influences upon its rate of timekeeping: a specialExpand
Quasi-uniform gravitational field of a disk revisited
We calculate the quasi-uniform gravitational field of a disk in the weak-field approximation and demonstrate an inappropriateness of preceding results. The Riemann tensor of this field is determined.Expand
Simultaneity and Precise Time in Rotation
I analyse the role of simultaneity in relativistic rotation by building incrementally on its role in simpler scenarios. Historically, rotation has been analysed in 1 + 1 dimensions; but my stance isExpand
Was Einstein an Engineer?
TLDR
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
Does Class Size Affect the Gender Gap? A Natural Experiment in Law
We study a unique natural experiment in which Stanford Law School randomly assigned first-year students to small or large sections of mandatory courses from 2001 to 2011. We provide evidence thatExpand
