While googling this morning, I found that today is the day the first LASER was invented.
Definitely, LASER was an important invention that has made our lives easier. So HAPPY LASER DAY to you all!
When the first working laser was reported in 16 May 1960, it was described as "a solution looking for a problem." But before long the laser's distinctive qualities—its ability to generate an intense, very narrow beam of light of a single wavelength—were being harnessed for science, technology and medicine. Today, lasers are everywhere: from research laboratories at the cutting edge of quantum physics to medical clinics, supermarket checkouts and the telephone network.
