Tributes have poured in from around the world for Stephen Hawking, the British physicist who amazed both scientists and the public and who passed away on Wednesday aged 76.
Euronews went to the Royal Observatory in Greenwich to ask people how they'll remember Hawking.
"An amazing man, and from all accounts a very funny man as well," said one visitor.
"Stephen Hawking is definitely going to be up there in the annals of physics for a very long time to come. His name is always being mentioned alongside other great figures like Isaac Newton and Albert Einstein," said Dr Marek Kukula, the Public Astronomer at the Royal Observatory in Greenwich.
"He made some really significant contributions to physics... people have built their careers on things that he did."
"He definitely inspired people to go into physics and maths – like myself – but I think he also inspired all sorts of people in all different walks of life.
"He obviously had to overcome a great deal of personal hardship in his own life to achieve what he achieved, and I think many people found that very inspirational."
