It is hard to believe that a person will defy the norms and take everybody by surprise with her performance. Nadia Comaneci from Romania did just that on July 18th by scoring a perfect 10 in gymnastics when the judges thought that it was unachievable. Such people inspire others to believe that nothing is impossible. Another such story is that of U.S president Barack Obama whose memoir ‘Dreams from My Father: A Story of Race and Inheritance’ was published on this day. This is not all, more lessons to learn were available in print as Adolf Hitler’s autobiography ‘Mein Kampf’ was published. Crucial steps for strengthening democracy were taken when Uruguay adopted its first constitution and Britain introduced voting by secret ballot. The courteous practice of greeting people with a ‘hello’ began on 18th July when Thomas Alva Edison said ‘Halloo’ into the phonograph. July 18 is an important day in music history too as Brenda Lee’s song ‘I’m Sorry’ became the number one hit and Selena Quintanilla Perez’s ‘Dreaming of You’ album was released. The world found an alternate source of energy in Atomic electric power, which was distributed for commercial use for the first time in United States.
