What was the 70s nickname?

The 1970s desire to “find oneself” often resulted in people getting naked in public. The height of the streaking craze came in 1974 when a naked man zoomed across the stage during the Academy Awards ceremony in Los Angeles. Tom Wolfe called the 1970s the ” Me Decade,” Across the land, Americans seemed determined to escape from the wars and social movements of the previous decade.

  • Disillusionment with national and global action led many to look inward and find solace in discovering more about themselves.
  • A magazine entitled Self sold thousands of copies.
  • Women demanded respect as equal partners.
  • Fashions veered toward the outrageous and ridiculous, reflecting the glorification of rule breaking and self-expression.

The sexual revolution took hold from the inner city to the small town. Therapy sessions mushroomed as Americans in all walks of life searched to find “the real me.” Many during the ’70s wore the “afro” hairstyle simply as a fashion statement. But to others it signified a shift toward more aggressive expressions of African American identity. Every rule of fashion was shattered in the 1970s. Lapels, ties, and collars, reached record widths.

The polyester leisure suit, available in a palette of citrus and pastel colors, was extremely popular among young males. The jacket, pants, and vest were often worn with an open collar to display thick necklace chains nestled in exposed chest hair. Hair was large and long for both males and females. Afros proved popular.

Sideburns were long and bushy. Bellbottom jeans and hiphuggers were the rage on many college campuses in the early 1970s. Platform shoes, which sometimes added as much as a foot to a person’s height, were introduced. Despite the machinations of the fashion industry, skirts remained short for much of the decade, and the string bikini shocked or delighted millions on America’s beaches. The platform shoe was just one of many fashion fads of the 1970s. Some platform shoes were so high that they increased the height of the wearer by a full foot. The sexual revolution had its roots in the 1960s, but this trend moved from the college campuses to the average American household in the 1970s.

Birth control was more widely used, and young people experienced more sexual partnerships with different people. Venereal diseases became much more widespread. As women asserted themselves economically, socially, and politically, the idea of remaining trapped in an unhappy marriage became less and less appealing.

Consequently, the divorce rate soared. An 1974 book entitled The Courage to Divorce encouraged individuals to put their own happiness above that of their spouses and children. With his leisure suit, bellbottoms, gold medallion and platform shoes, John Travolta brought disco culture to the big screen as “Tony Manero” in the 1977 film Saturday Night Fever, Nowhere was the self-indulgence of the 1970s more evident than in the fads of the decade.

  1. New forms of therapy were introduced to help a person find oneself.
  2. Disco music and the disco scene capitalized on the widespread desire to forget daily troubles and just have fun.
  3. Temperature-sensitive mood rings were a bogus attempt to display inner feelings outwardly.
  4. Public streaking showed a desire to break society’s norms and to show comfort with one’s own body.

The height of the ridiculous was reached in 1975 when an entrepreneur named Gary Dahl sold common rocks to thousands of Americans advertised as the pet rock, These “pets” were peddled with accessories and guidebooks, incurring the wrath of cultural critics across the nation who believed a new low had been reached.

From Wikipedia, the free encyclopedia “Gya” redirects here. For the village of Ladakh, India, see Gia, Leh, History of the universe timelines usually use the Gya or “billion years ago” scale. A billion years or giga-annum (10 9 years ) is a unit of time on the petasecond scale, more precisely equal to 3.16 × 10 16 seconds (or simply 1,000,000,000 years). It is sometimes abbreviated Gy, Ga (“giga-annum”), Byr and variants.

The abbreviations Gya or bya are for “billion years ago”, i.e. billion years before present, The terms are used in geology, paleontology, geophysics, astronomy, and physical cosmology, The prefix giga- is preferred to billion – to avoid confusion in the long and short scales over the meaning of billion; the postfix annum may be further qualified for precision as a sidereal year or Julian year : 1 Ga j = 3.155 76 × 10 16 s, 1 Ga s = 3.155 81 × 10 16 s (epoch J2000.0 ).1 Ga s = 1 × 10 9 y Byr was formerly used in English-language geology and astronomy as a unit of one billion years,

Subsequently, the term gigaannum (Ga) has increased in usage, with Gy or Gyr still sometimes used in English-language works (at the risk of confusion with Gy as abbreviation for the gray, a unit of radiation exposure). Astronomers use Gyr or Gy (or Ga, where the a stands for annum, Latin for “year”) as the symbol for gigayear,

Are we in the 3rd millennium?

The numbering of years and calendrical reckoning has always been a controversial topic. The civil calendar used in most countries is also known as the Gregorian calendar. The initial epoch (first year) of the Common Era (CE) is 1 CE also known as AD 1.

  • The first century comprises the years AD 1 through AD 100.
  • The second century began with AD 101 and continued through AD 200.
  • By extrapolation, the 20th century comprises the years AD 1901-2000.
  • Therefore, the 21st century began on 1 January 2001 and will continue through 31 December 2100.
  • Similarly, the 1st millennium comprised the years AD 1-1000.

The 2nd millennium comprised the years AD 1001-2000. The 3rd millennium began with AD 2001 and will continue through AD 3000. Over recorded history, many initial epochs have been used for calendrical reckoning. Frequently, years were counted from the ascension of a ruler.

For a calendrical epoch to be useful, however, it must be tied to a sequence of recorded historical events. The initial year of the Common Era was chosen to be first year to commence after the birth of Christ. This is the initial epoch of the Julian and Gregorian calendars. This epoch was established by the 6th century scholar Dionysius Exiguus who was compiling a table of dates of Easter.

Dionysius followed a previous precedent, extending an existing table (by Cyrillus) covering the period 228-247. This table was reckoned from the beginning of the reign of Emperor Diocletian. However, Dionysius did not want his Easter table “to perpetuate the memory of an impious persecutor of the Church, but preferred to count and denote the years from the Incarnation of our Lord Jesus Christ.” To accomplish this, he designated the years of his table Anni Domini Nostri Jesu Christi 532-550.

  1. Thus, Dionysius’ Anno Domini 532 is equivalent to Anno Diocletiani 248, establishing a correspondence between the new Christian Era and an existing system associated with historical records.
  2. Dionysius did not, however, establish an accurate date for the birth of Christ.
  3. Scholars generally believe that Christ was born a few years before AD 1, but the records are too sketchy to allow a definitive dating.

How are dates prior to an initial epoch recorded? Today it appears obvious that a year designated 1 would be preceded by year 0, which would be preceded by year -1, etc. But the concept of both 0 and negative numbers did not come into common use in Europe until the 16th century.

  • Even then, these concepts were initially only of interest to mathematicians.
  • Their application to chronological problems did not occur for two more centuries.
  • Instead, years were counted using a succession of initial epochs.
  • Even as Dionysius’ practice of dating from the Incarnation became common in ecclesiastical writings of the middle ages, traditional dating practices continued for civil purposes.

In the 16th century, Joseph Justus Scaliger tried to resolve the patchwork historical eras by placing everything on a single system. Not being ready to deal with negative year counts, he sought an initial epoch in prior to any historical record. His approach was numerological and utilized three calendrical cycles:

the 28-year solar cycle, the 19-year Golden Number cycle, and the 15-year indiction cycle.

The solar cycle is the period after which week days and calendar dates repeat in the Julian calendar. The Golden Number cycle is the period after which moon phases repeat (approximately) on the same calendar dates. The indictions originally referred to the periodic reassessment for an agricultural or land tax in late third-century Roman Egypt.

Scaliger could characterize a year by the combination of numbers (S,G,I), where S runs from 1 through 28, G from 1 through 19, and I from 1 through 15. A given combination will recur after 7980 (= 28 x 19 x 15) years. He called this a Julian cycle because it was based on the Julian calendar. Scaliger knew that the year of Christ’s birth (as determined by Dionysius Exiguus) is characterized by the number 9 of the solar cycle, by Golden Number 1, and by number 3 of the indiction cycle, or (9,1,3).

Scaliger chose as this initial epoch the year characterized by (1,1,1) and determined that (9,1,3) was year 4713 of his chronological era. John Herschel later adopted Scaliger’s initial epoch for the Julian Day numbers used by astronomers. We would say that Scaliger’s initial epoch was 4713 BC or -4712.
