March 14 is known as Pi Day. This date is also the birthday of Albert Einstein (March 14, 1879). Also, on March 14, 2018, Stephen Hawking passed away. We already wrote about that in the article about Albert Einstein and Stephen Hawking and related stamp issues.

His most important, and publicly known work was developing the theory of relativity. That work changes the understating of space, time, and gravity. Albert passed away on April 18, 1955, in Princeton, New Jersey.

Albert Einstein's formula: E=mc2

Albert Einstein is so well-known; I believe almost anyone who had Internet access would recognize his picture. Almost the same stands for the mass–energy equivalence, described by Einstein’s formula E=mc2.

Einstein presented this formula for the first time in 1905 in the paper titled "Does the Inertia of a Body Depend Upon Its Energy Content?".

This equation is extremely important because it describes the relationship between mass and energy. Energy (E) is equal to mass (m) times the speed of light (c) squared.

This formula implies that a small mass can be converted into a large amount of energy and that is the basis for nuclear reactions.

Theory of Relativity

The theory of relativity compromises of two main parts: special relativity and general relativity.

Special relativity is based on two postulates:

  1. “The laws of physics are invariant (identical) in all inertial frames of reference (that is, frames of reference with no acceleration).
  2. The speed of light in vacuum is the same for all observers, regardless of the motion of light source or observer.”

General relativity expands this and describes gravity as the curvature of spacetime caused by the presence of mass and energy.
