Ian Leslie’s “John and Paul” traces the shared journey of John Lennon and Paul McCartney before, during and after The Beatles, offering us both a new look at two of the greatest icons in music history, and rich insights into the nature of creativity, collaboration, and human intimacy.
The two shared a private language, rooted in the stories, comedy and songs they both loved as teenagers, and later, in the lyrics of Beatles songs.
General relativity has entered a new phase of its development as technical advances have led to the direct detection of gravitational radiation from the merging of single pairs of stellar-sized black holes.
The exquisite sensitivity of pulsar signal timing measurements has also been exploited to reveal the presence of a background of gravitational waves, most likely arising from the mergers of supermassive black holes thought to be present at the center of most galaxies.
This book demonstrates how general relativity is central to understanding these and other observations.
