Title: वैकल्पिक

Text: The theory of special relativity replaces the Galilean group with the Poincare group. This makes the equations of motion of a particle in an external field only slightly more complicated. However, physics at high velocities looks quite different from its nonrelativistic limit. प्रत्येक पराग्राफले परीक्षण हुनेछ।
