The 1970s was also an era of great technological and scientific advances; since the appearance of the first commercial microprocessor, the Intel 4004 in 1971, the decade was characterised by a profound transformation of computing units - by then rudimentary, spacious machines - into the realm of portability and home accessibility.
On the other hand, there were also great advances in fields such as physics, which saw the consolidation of Quantum Field Theory at the end of the decade, mainly thanks to the confirmation of the existence of quarks and the detection of the first gauge bosons in addition to the photon, the Z boson and the gluon, part of what was christened in 1975 as the Standard Model.
Novelist Tom Wolfe coined the term " 'Me' decade" in his essay "The 'Me' Decade and the Third Great Awakening", published by New York Magazine in August 1976 referring to the 1970s. The term describes a general new attitude of Americans towards atomized individualism and away from communitarianism, in clear contrast with the 1960s.
The Disco scene was very popular in the 1970s
During the early 1970s, popular music continued to be dominated by musicians who had achieved fame during the 1960s such as the Rolling Stones, The Who, Elvis Presley, Bob Dylan, The Grateful Dead, and Eric Clapton. In addition, many newcomer rock groups such as Black Sabbath
The 1970s saw the rapid commercialization of rock music, and by mid-decade there were a spate of bands derisively dubbed "corporate rock" due to the notion that they had been created by record labels to produce simplistic, radio-friendly songs that offered clichés rather than meaningful lyrics. Such bands included The Doobie Brothers, Bread, Styx, Kansas, and REO Speedwagon.
Funk, an offshoot of soul music with a greater emphasis on beats, and influences from rhythm
and blues, jazz, and psychedelic rock, was also very popular. The mid-1970s also saw the rise of disco music, which dominated during the last half of the decade with bands like the Bee Gees, Chic, ABBA, Village People, Boney M, Donna Summer, KC and the Sunshine Band, and others. In response to this, rock music became increasingly hard-edged, with early metal artists like Led Zeppelin, Jimi Hendrix, Black Sabbath, and Deep Purple. Minimalism also emerged, led by composers such as Philip Glass, Steve Reich
The 70s has often been seen as a time of social and national crisis, key in destabilisation of the post-war settlement and in bringing about a turn to the right from 1979 under Margaret Thatcher. Others have pointed out that the decade saw levels of equality at an historical high and that the experience for many was of social security, on the one hand, and liberation, on the other (albeit tendencies that were arguably in tension). Until recently, there was little historical work that took us into such recent realms of national history, but the period is now fast emerging as a focus for exciting new historical research. You will have the opportunity to engage with the emerging debates and to make your own contribution through original research.and Michael Nyman. Led Zeppelin appeared.
