I obtained an analytical description of time dilation and length contraction which describes(adsbygoogle = window.adsbygoogle || []).push({}); whythese occur at high speeds. However there was no such analysis of Einstein's famous equation E=m(c squared).

Instead, a derivation that I found in http://www.karlscalculus.org/einstein.html [Broken] starts off with

m =

m0

√1 - v2/c2

Then they derive the formula using calculus.

Is an analytical treatment for E=m(c squared) possible? Is there any thought experiment which helps us to realise the applicability of the mass-energy equivalence?
