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. At 25, Physicist Lawrence Bragg is the youngest person to receive a Nobel Prize. Atom is over 99.9% empty space. The most powerful lasers are made with Neodymium-doped Yttrium crystals. In a fraction of a second, they produce more power than the whole United States. Sunlight exerts pressure (solar radiation pressure). The effect of Relativity made Astronaut Sergei Avdeyev a fraction of a second younger upon his return to Earth after 747 days in space.
