Albert Einstein 
Albert  Einstein  (14  March  1879    18  April  1955)  was  a  German-born  theoretical 
physicist,  widely  acknowledged  to  be  one  of  the  greatest  physicists  of  all  time. 
Einstein  is  known  for  developing  the  theory  of  relativity,  but  he  also  made 
important   contributions   to   the   development   of   the   theory   of   quantum 
mechanics.  
 
Throughout   his   life,   Einstein   published   hundreds   of   books   and   articles.   He 
published  more  than  300  scientific  papers  and  150  non-scientific  ones.  On  5 
December  2014,  universities  and  archives  announced  the  release  of  Einstein's 
papers,  comprising  more  than  30,000  unique  documents.  Einstein's  intellectual 
achievements  and  originality  have  made  the  word  "Einstein"  synonymous  with 
"genius". 
In  1905,  a  year  sometimes  described  as  his  annus  mirabilis  ('miracle  year'), 
Einstein  published  four  groundbreaking  papers.  These  outlined  the  theory  of  the 
photoelectric  effect,  explained  Brownian  motion,  introduced  special  relativity, 
and  demonstrated  mass-energy  equivalence.  Einstein  thought  that  the  laws  of 
classical    mechanics    could    no    longer    be    reconciled    with    those    of    the 
electromagnetic field, which led him to develop his special theory of relativity. 
These  four  works  contributed  substantially  to  the  foundation  of  modern  physics 
and changed views on space, time, and matter. The four papers are: 
 
Title (translated) 
Significance 
"On a Heuristic Viewpoint 
Resolved an unsolved puzzle by suggesting that 
Concerning the Production 
and Transformation of 
Light" 
energy is exchanged only in discrete amounts 
(quanta). This idea was pivotal to the early 
development of quantum theory. 
"On the Motion of Small 
Particles Suspended in a 
Stationary Liquid, as 
Required by the Molecular 
Kinetic Theory of Heat" 
Explained empirical evidence for the atomic 
theory, supporting the application of statistical 
physics. 
"On the Electrodynamics of 
Moving Bodies" 
Reconciled Maxwell's equations for electricity 
and magnetism with the laws of mechanics by 
introducing changes to mechanics, resulting 
from analysis based on empirical evidence that 
the speed of light is independent of the motion 
of the observer. Discredited the concept of a 
"luminiferous ether". 
"Does the Inertia of a Body 
Depend Upon Its Energy 
Content?" 
Equivalence of matter and energy, E = mc2 
(and by implication, the ability of gravity to 
"bend" light), the existence of "rest energy", 
and the basis of nuclear energy. 
 
He  then  extended  the  theory  to  gravitational  fields;  he  published  a  paper  on 
general  relativity  in  1916,  introducing  his  theory  of  gravitation.  In  1917,  he 
applied  the  general  theory  of  relativity  to  model  the  structure  of  the  universe. 
He   continued   to   deal   with   problems   of   statistical   mechanics   and   quantum 
theory,   which   led   to   his   explanations   of   particle   theory   and   the   motion   of 
molecules.  He  also  investigated  the  thermal  properties  of  light  and  the  quantum 
theory  of  radiation,  which  laid  the  foundation  of  the  photon  theory  of  light. 
However,  for  much  of  the  later  part  of  his  career,  he  worked  on  two  ultimately 
unsuccessful   endeavors.   First,   despite   his   great   contributions   to   quantum 
mechanics,  he  opposed  what  it  evolved  into,  objecting  that  nature  "does  not 
play  dice".  Second,  he  attempted  to  devise  a  unified  field  theory  by  generalizing 
his  geometric  theory  of  gravitation  to  include  electromagnetism.  As  a  result,  he 
became increasingly isolated from the mainstream of modern physics.

This demo illustrates the level of control the DevExpress ASP.NET MVC Rich Text Editor (RichEdit extension) provides to you when your business logic requires you to restrict some behavior and formatting options available to end-users within a document. You are able to prevent certain operations (such as open/save or copy/paste) from being performed within a document and to limit document characteristics (such as character or paragraph formatting) that can be changed.
