"To stimulate creativity, one must develop the childlike inclination for play and the childlike desire for recognition." Albert Einstein (March 14, 1879 – April 18, 1955) was a German-born theoretical physicist who developed the general theory of relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics and the most influential physicist of the 20th century.
It's widely known that Einstein shunned traditional methods which drove him to use the creative side of the brain. He often suggested, "opening the universe of the mind." Perhaps this is what made him a great scientist. He looked at things through different eyes to find the hidden solutions to problems.
