Wolfson, a physics professor at Middlebury College, takes the fear out of Einstein's relativity theory in this brisk piece of pop science. The author uses a tennis game on Venus and a cup of hot tea ...

“The chief attraction of the theory lies in its logical completeness,” wrote Albert Einstein after publishing his general theory of relativity in 1915. “If a single one of the conclusions drawn from ...

Einstein's theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. When you purchase through links on our site, we may earn ...
