- 1. the absence of standards of absolute and universal application: "moral relativity"
- 2. the dependence of various physical phenomena on relative motion of the observer and the observed objects, especially regarding the nature and behavior of light, space, time, and gravity.
It is assumed in pre-relativity physics that the laws of the configuration of ideal rigid bodies are consistent with Euclidean geometry. What this means may be expressed as follows: Two points marked on a rigid body form an interval. Such an interval can be oriented at rest, relatively to our space of reference, in a multiplicity of ways.
The Meaning of Relativity is the focus of a 2017 book, The Formative Years of Relativity by Hanoch Gutfreund and Jürgen Renn, which described The Meaning of Relativity as "Einstein's definitive exposition of his special and general theories of relativity".
Relativity, wide-ranging physical theories formed by the German-born physicist Albert Einstein. Special relativity is limited to objects that are moving with respect to inertial frames of reference. General relativity is concerned with gravity, one of the fundamental forces in the universe.

Feb 6, 2021 · Like Newton and Galileo before him, this remarkable scientist changed forever mankind's understanding of the universe. In 1921, five years after proclaiming his general theory of relativity, Einstein was awarded the Nobel Prize for Physics in recognition of his remarkable achievements.
Oct 26, 2014 · These four lectures constituted an overview of his then-controversial theory of relativity. Princeton University Press made the lectures available under the title The Meaning of Relativity, the first book by Einstein to be produced by an American publisher.
THE MEANING OF RELATIVITY. LECTURE I SPACE AND TIME IN PRE-RELATIVITY PHYSICS. T HE theory of relativity is intimately connected with the theory of space and time. I shall therefore begin with a brief investigation of the origin of our ideas of space and time, although in doing so I know that I introduce a controversial subject.
It says that the energy ( E) associated with an object – an atom, a person or a whole galaxy – is equal to its total mass ( m) multiplied by the square of the speed of light (c). As the speed of light is about 300,000 km s -1, this means there is a whole lot of energy tied up in any mass.
Einstein’s theories of relativity have had a profound effect on the development of physics throughout the past century; they sparked the ongoing pursuit of a unified physical theory that would underlie all others and explain the properties and behavior of all particles and forces in nature.
