When we consider the great minds of many centuries and ask the question of what makes someone a great scientist, there are many aspects we should evaluate.
Sample Writing
Para. 1: introduction
Looking at the lives of Qian Xuesen and Stephen Hawking, some common characteristics surface: they are knowledgeable, gifted, self-sacrificing for greater good of the country or humanity, brave and determined. In short, they have the perseverance to chase down solutions to big problems and not let discouragement set in during their discovery process.
Sample Writing
Para. 2: quality 1 + story
We can see this in Qian Xuesen’s life, pioneering to another country to work with and inspire like-minded people in his field and to cooperate on their work. We can see it in his enthusiasm to return to China and lead the aerospace programme through its birthing stages.
