Okun on confusion about Einstein&#8217;s famous mass and energy formula.  <\/p>\n<blockquote><p><b>Abstract:<\/b>The article traces the way Einstein formulated the relation between energy and mass in his work from 1905 to 1955. Einstein emphasized quite often that the mass $m$ of a body is equivalent to its rest energy $E_0$. At the same time he frequently resorted to the less clear-cut statement of equivalence of energy and mass. As a result, Einstein&#8217;s formula $E_0=mc^2$ still remains much less known than its popular form, $E=mc^2$, in which $E$ is the total energy equal to the sum of the rest energy and the kinetic energy of a freely moving body. One of the consequences of this is the widespread fallacy that the mass of a body increases when its velocity increases and even that this is an experimental fact. As wrote the playwright A N Ostrovsky &#8220;Something must exist for people, something so austere, so lofty, so sacrosanct that it would make profaning it unthinkable.&#8221; <\/p><\/blockquote>\n<p>Reminds me of a (apocryphal?) story my <a href=\"http:\/\/cosmo.nyu.edu\/hogg\/\">Physics 1 TA<\/a> told me.  He described how a friend of his, who was rather geekly looking, you known glasses with tape holding them together stuff, was walking down the street one day when a group of local yokels drove by.  The group, spotting the weak geek sought immediately went into yokel mocking mode and so shouted at him &#8220;Hey geek!  E equals MC squared!&#8221;  The geek thought for a few seconds and yelled back &#8220;Only in the rest frame!&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Physics and Physicists points to an article: &#8220;The Einstein formula: E_0=mc^2 &#8216;Isn&#8217;t the Lord laughing?&#8217;&#8221; by L.B.
