On the eve of Father's Day, we talk to the daughter of physicist Stephen Hawking and the father of a boy with a terrible incurable disease about the challenges of their relationships It is almost impossible to write about her without mentioning her father - world-renowned cosmologist Professor Stephen Hawking - whose contributions to the field of science in the 20th century are often compared with those of Einstein and Newton. But Lucy Hawking, 35, who accompanied her father on his first visit to Hong Kong, appreciates that she would not be the person she is if it had not been for her amazing father. 'It is obviously an extraordinary life. It is a different life ... it is a different style of family,' Ms Hawking said. A novelist, freelance journalist and mother of one, Ms Hawking speaks directly, often cutting straight to the point. 'Life is about acceptance. It is accepting that things are the way they are and making the best of it ... my dad gave a good example of that,' she said. Ms Hawking, however, said her father never pressured her or her two brothers to follow his path. 'Dad is very proud of who we are, rather than what we have done,' she said. 'He has been a strong example of determination, generosity, intellectual inquiry and of not giving up - the value of keeping going and doing what you believe in.' Although her father is confined to a wheelchair, Ms Hawking said he always wanted to do as much as he could for himself. 'It is his love of life, and also his determination [that has kept him going], and you see this reflected in his desire to do as much as he can,' she said. Having published two novels, Ms Hawking is now joining forces with her father to work on a book for children about theoretical physics. 'I am writing the story - my strength is in creative writing - and he is in charge of the physics. It is blending the two together to make a story for children about the wonders of the universe,' she said. Professor Hawking will leave for Beijing today after a six-day stay in Hong Kong, during which he met Chief Executive Donald Tsang Yam-kuen and academics, but also found time to sightsee and enjoy good food on the Peak. The highlight of his visit, organised by the Hong Kong University of Science and Technology, was Thursday's lecture at the tertiary institution on the origins of the universe. Taking a break from their tight schedule, Ms Hawking yesterday went sightseeing in Stanley. Professor Hawking has three children with his first wife, Jane. The eldest son, Robert, 39, has emigrated to the United States, but the youngest son, Tim, 27, and Ms Hawking both live in Britain. Before becoming a journalist, Ms Hawking read French and Russian at Oxford. She married Alex Mackenzie Smith - a member of the United Nations Peace Corps in Bosnia - in 1998, the year after their son, William, was born. The couple are no longer together.
