Because various parts of an object are different distances from an observer, and light takes a finite time to reach the observer, the appearance of a relativistically moving object will be very different from that given by the Lorentz contraction. We derive equations that can be applied to a photographic image so that the Lorentz contraction can still be observed. We also give equations that quantify the apparent deformation of the object and plots that show the apparent speed of the object as… Expand
Gamow’s cyclist: a new look at relativistic measurements for a binocular observer
TLDR
A rigorous re-analysis of the cyclist, this time in three dimensions, is undertaken for a binocular observer, accounting for both the distortion in apparent position and the relativistic colour and intensity shifts undergone by a fast-moving object. Expand
The Apparent Velocity and Acceleration of Relativistically Moving Objects
Although special relativity limits the actual velocity of a particle to $c$, the velocity of light, the observed velocity need not be the same as the actual velocity as the observer is only aware ofExpand
Observation of relativistic effects by a single observer: a geometric interpretation using Loedel diagrams
The apparent length of a relativistically moving rod and visualization of the Einstein time dilation are studied. The description of events in space-time is given geometrically as viewed from twoExpand
Illustrating the space-time coordinates of the events associated with the apparent and the actual position of a light source
We present a space-time diagram that displays in true values the space- time coordinates of events associated with the apparent and actual positions of a point like source moving with constantExpand
The differential aging of inertial and non-inertial observers: The Eyewitness observations of a relativistic polygon traveler
The time dilation of non-inertial travelers in circular and polygonal closed paths are well known. In both cases observers completing a round trip will age less than an observer at rest with respectExpand
Deformações geométricas e velocidade superluminal aparentes em objetos em movimento relativístico
In this work, continuing the previous one of Ostermann and Ricci (Caderno Catarinense de Ensino de Fisica 19, 176 (2002)), we analyze some apparent geometrical deformations of three objects inExpand
Relativity for games
We present how to implement special relativity in computer games. The resultant relativistic world shows the time dilation and Lorentz contraction exactly, not only for the player but also for allExpand
Visualizing Flat Spacetime: Viewing Optical versus Special Relativistic Effects
A visual representation of Minkowski spacetime appropriate for a student with a background in geometry and algebra is presented. Minkowski spacetime can be modeled with a Euclidean four-space toExpand

TLDR
The power spectral formula of the Cherenkov radiation of the system of two equal charges is derived in the framework of the source theory and can be used to verify the Lorentz contraction of the relativistic length. Expand
Some Subtle Concepts in Fundamental Physics
In this paper, we discuss some subtle concepts, such as coordinate, measurement, simultaneity, Lorentz-FitzGerald contraction, singularity in fundamental physics. The explanations of these conceptsExpand

On the apparent visual forms of relativistically moving objects
SummaryThe question of the apparent visual shape of an object moving at relativistic speeds, as perceived by a single observer, is analysed afresh. It is shown by qualitative arguments that theExpand
The visual appearance of rapidly moving objects
I would like to draw the attention of physicists to a recent paper by James Terrell in which he does away with an old prejudice held by practically all of us. We all believed that, according toExpand
Invisibility of the Lorentz Contraction
It is shown that, if the apparent directions of objects are plotted as points on a sphere surrounding the observer, the Lorentz transformation corresponds to a conformal transformation on the surfaceExpand

The two‐dimensional or ’’photographic’’ appearance of a cube moving at relativistic speeds is investigated. It is shown that the appearance of the cube depends upon whether the camera is held fixedExpand
A Texture Mapping Approach for the Visualization of Special Relativity

This paper describes a novel rendering technique based on the relativistic aberration of light and makes use of texture mapping that allows for a physically correct treatment of the geometric quantities that effect the calculation of illumination. Expand
Time dilation visualization in relativity
TLDR
As the authors introduce the physics of special relativity into ray-tracing and make time to pass as a ray travels through space, they are able to link the spatial and temporal dimensions in a fundamental and consistent way in their simulations, and generate images that reveal theatial and temporal properties of the 4D geometry of spacetime.
