Painter, sculptor, anatomist, architect, engineer, inventor, musician, mathematician and philosopher, Leonardo da Vinci was the greatest genius to have ever walked this earth. As a child Leonardo barely attended school, never trained in the classics, and was not formally taught how to think. He learned purely by observing nature; the flowing streams, the falling leaves, and painstakingly drew what he observed. From the Mona Lisa to the Last Supper, he conceived of ideas way ahead of his time; helicopter, tank, solar power, and numerous others. The world will probably never again experience so much breadth of talent, in one man. Leonardo's diversity of knowledge should inspire Leaders to explore a wide range of disciplines and transfer learning's from there to the straight-jacketed world of business management.
Isaac Newton was a mathematician, physicist, astronomer and alchemist, widely regarded as one of the greatest scientists and mathematicians in history. Newton discovered universal gravitation and the three laws of motion, laying the groundwork for classical mechanics. His obsessive questioning, combined with deep intellect and great perseverance, drove him to explore and ultimately prove his ideas. His intuition, and ability to question the most routine and natural process, stands testimony to his genius. Newton said - "If I have seen farther than others, it is because I have stood on the shoulders of giants".
