The world is mourning the loss of famed physicist Stephen Hawking after he passed away in his home on Wednesday at the age of 76.

As a means of honoring their longtime colleague, Cambridge University published a touching video tribute with a clip from a speech that Hawking gave for his 75th birthday.

Hawkings says: "So remember to look up at the stars and not down at your feet try to make sense of what you see and wonder about what makes the universe exist be curious and however difficult life may seem there is always something you can do and succeed at. It matters that you don't just give up."
