 The Meaning of Einstein's EquationJohn
Baez and Emory BunnOnline  NA Pages  EnglishThis is a brief introduction to general relativity, designed
for both students and teachers of the subject. It mainly deals with Einstein's
Equation and Some Consequences.
 Does mass really depend on velocity, Dad  Einstein and the existence of atomNAOnline  NA Pages  EnglishThe background of Einstein’s 1905 Brownian motion paper is
discussed, including the work of people like Brown, Boltzmann, and Bachelier.
The paper is discussed as is its aftermath. The question is raised as to whether
atoms exist.
