(there is translated in english the second article Einstein published in Annalen der physik about special relativity -thanks dex, i missed last- in german)
 Sci Advisor HW Helper P: 11,834 It was his second article on SR in 1905 and the IV-th overall in that year. http://www.aip.org/history/einstein/chron-1905.htm Daniel.

## Derivation of E=mC2

thanks Rebel and dextercioby for the required information
 P: 100 You can simply take this integral and you'll get $$E = mc^2$$ $$\int^c_0{P dv} ;$$ where $$P = mv\gamma$$ and $$\gamma = \frac{1}{\sqrt{1 - (\frac{v}{c})^2}}$$ $$\int^c_0 {\frac{mv}{\sqrt{1 - (\frac{v}{c})^2}} dv = mc^2$$
