We present visual calculations in special relativity using spacetime diagrams drawn on graph paper that has been rotated by 45 degrees. The rotated lines represent lightlike directions in Minkowski spacetime, and the boxes in the grid (called "light-clock diamonds") represent units of measurement modeled on the ticks of an inertial observer's lightclock. We show that many quantitative results can be read off a spacetime diagram by counting boxes, using a minimal amount of algebra. We use the… Expand

A Useful Form of the Minkowski Diagram
We give a diagrammatic representation of the diagonal form of the special Lorentz transformation. The null coordinates x±ct are plotted along a single set of orthogonal axes. Special LorentzExpand
A Geometrical Introduction to Special Relativity
Some of the basic ideas of special relativity are developed through graphical representation of the results of two “thought experiments” with moving rods. The influence of the postulates of theExpand
Space–time intervals as light rectangles
Two inertial observers in relative motion must each see the other’s clock running at the same rate. The representation of this symmetry of the Doppler effect in a two-dimensional space–time diagramExpand
In special relativity, the definition of coordinate systems adapted to generic accelerated observers is a long-standing problem, which has found unequivocal solutions only for the simplest motions.Expand
Spacetime and Euclidean geometry
Using only the principle of relativity and Euclidean geometry we show in this pedagogical article that the square of proper time or length in a two-dimensional spacetime diagram is proportional toExpand

Dirac’s light‐cone coordinate system
It is shown that Dirac’s light‐cone coordinate system provides an effective method for treating the geometry of Lorentz transformation in a rectangular coordinate system. Transformation properties ofExpand
Operational Approach to Space and Time Measurements in Flat Space
The problem of making the space-time measurements that constitute an arbitrary reference frame is discussed within the framework of special relativity. An operational approach to such measurements isExpand
Forms of Relativistic Dynamics
For the purposes of atomic theory it is necessary to combine the restricted principle of relativity with the Hamiltonian formulation of dynamics. This combination leads to the appearance of tenExpand
On radar time and the twin “paradox”
In this paper we apply the concept of radar time (popularized by Bondi in his work on k calculus) to the well-known relativistic twin “paradox.” Radar time is used to define hypersurfaces ofExpand
