Due to the effect of Thermal Expansion, the Eiffel Tower is upto 15cm taller in summer. Radar is an abbreviation ofRadio Detection And Ranging. If an atom were the size of a stadium, its electrons would be as small as bees. Laser is an abbreviation ofLight Amplification byStimulated Emission ofRadiation. Light does not age.
