General Relativity from A to Z

To mark the 100-year anniversary of the theory that re-wrote the rule book of physics, Perimeter presents an overview of general relativity, alphabetized for your convenience.

In 1915, Albert Einstein published the idea that revolutionized how we decipher the universe: general relativity. 

General relativity is the geometric theory of gravity that gives us the building blocks we need to deeply understand the nature of space and time (and, as an added bonus, navigate by GPS).

We used some different blocks, of the alphabetical variety, to celebrate the centenary of what has been called “the most beautiful of theories.”

About Perimeter Institute

Perimeter Institute is the world’s largest research hub devoted to theoretical physics. The independent Institute was founded in 1999 to foster breakthroughs in the fundamental understanding of our universe, from the smallest particles to the entire cosmos. Research at Perimeter is motivated by the understanding that fundamental science advances human knowledge and catalyzes innovation, and that today’s theoretical physics is tomorrow’s technology. Located in the Region of Waterloo, the not-for-profit Institute is a unique public-private endeavour, including the Governments of Ontario and Canada, that enables cutting-edge research, trains the next generation of scientific pioneers, and shares the power of physics through award-winning educational outreach and public engagement.
