The person I admire the most is the scientist Stephen William Hawking. He was born on January 8, 1942 in Oxford, England. Stephen was famous for his work on the basic laws of the universe. he was also known for how he copes with motor neuron disease (INN). 2 Stephen studied physics at University College, Oxford. he was diagnosed with MND at university. Stephen slowly lost control of his muscles and eventually couldn't walk. despite this, he finished his studies, got married and started a career at the university. 3 a few years later, he completely lost his voice. unfortunately, he was in the middle of writing a book at the time and suddenly couldn't communicate except by blinking. the computer system on his wheelchair allowed him to speak. of his many books, "A Brief History of Time" is Stephen's bestseller. Hawking died on March 14, 2018. 4. The reason I admire him is that he was very smart and brave, and he never gave up on life. When I think about him, I know that anything is possible as long as you really want it and work hard to achieve it. /
