As I have written about several times this year, 2015 marks the 100th anniversary of the first publication of The General Theory of Relativity and, as expected, the books and articles are coming thick and fast.
The latest contribution is a Scientific American special Issue: 100 years of General Relativity. Contributors include Brian Greene, Walter Isaacson, Lawrence Krauss and Corey S, Powell. There are familiar subjects: essays about the history of the publication, his importance, his personality and his mistakes. However, one article in particular caught my attention. It is called Relativity’s Reach and contains a map of Einstein’s influence. It’s premise is that many of the ideas at the limits of physics, such as M-theory and de Sitter universes rely on Einstein’s masterwork on gravity and the bending of space and time.
The article relies on the analysis of 2435 abstracts of 2014 physics papers for 61 keywords, each of which represents a research topic that has grown out of general relativity, which is then visually represented.. It leads to a visually interesting map and reveals the depths to which Einstein’s work influences current ideas at the cutting edge of physics. And remember, this is just his work on General relativity; it doesn’t touch his work on Quantum Theory and Special relativity.
For a complete list of the current works that Einstein’s work is the cornerstone for, you will need to see the article, but it includes: multiverse, accelerating universe, standard model, supersymmetry, cosmology, string theory, quantum gravity, dark matter and gravitational waves.
Einstein’s influence remains deep and persuasive. It not only underpins much of our daily lives through technology, but also the ideas at the very edge of our understanding about the universe and the world in which we live.
