Jupiter

 Jupiter rotates the fastest of all the planets in the solar system, completing one rotation on its axis in just under ten hours. This causes an equatorial bulge that is visible through a simple telescope. Jupiter's upper atmosphere rotates differentially because it is not a solid entity. The polar atmosphere of Jupiter rotates more slowly than the equatorial atmosphere, by around 5 minutes. The planet is an oblate spheroid, which means that the distance between its poles and across its equator is greater than the distance between those two distances. The equatorial diameter of Jupiter is 5,764 miles greater than the polar diameter.

Jupiter is the biggest planet in the Solar System, and the fifth planet from the Sun. It is a gas giant with a mass that is slightly less than one thousandth that of the Sun but more than two and a half times that of all the other planets in the Solar System put together. After the Moon and Venus, Jupiter is the third brightest natural object in the Earth's night sky, and people have been seeing it since ancient times. It was given the name Jupiter after the Roman god and supreme deity.

When Pioneer 10 made its closest approach to Jupiter in December 1973, it became the first spacecraft to visit the planet. Since then, other robotic spacecraft have studied Jupiter, starting with the Pioneer and Voyager flyby missions from 1973 to 1979 and continuing with the Galileo orbiter in 1995. The New Horizons spacecraft visited Jupiter in 2007 by accelerating through its gravity and curving its course toward Pluto. Juno, the most recent spacecraft to explore the planet, orbited Jupiter in July 2016. The likely ice-covered liquid ocean of Europa is a future target for study in the Jupiter system.

Lenny Bruce

 In 1964, comedian Lenny Bruce was convicted of obscenity in New York, a landmark case that highlighted tensions between free speech and public decency laws. Known for his provocative and often controversial routines, Bruce challenged societal norms by addressing taboo topics such as religion, politics, and sex with raw honesty. He was arrested for using “over 100 obsene” words while on stage at Greenwich Village by undercover police officers who deemed his language indecent. Bruce was found guilty and sentenced to four months in a workhouse, though he died before his appeal could be heard.

Simon & Garfunkel

 Simon & Garfunkel were one of the most influential folk-rock duos of the 1960s, blending poetic lyrics with intricate harmonies. Consisting of Paul Simon and Art Garfunkel, the duo first gained recognition in 1965 when "The Sound of Silence" became a surprise hit. Originally an acoustic track on their 1964 debut album Wednesday Morning, 3 A.M., the song initially failed to gain traction. However, producer Tom Wilson later added electric instrumentation, transforming it into a folk-rock anthem that soared to No. 1 on the Billboard Hot 100.

Another defining hit, "Mrs. Robinson," was released in 1968 and became synonymous with the film The Graduate, starring Dustin Hoffman. The song's lyrics, while partly enigmatic, include references to the loss of American innocence, with the famous line, "Where have you gone, Joe DiMaggio?" capturing a sense of nostalgia. The song won the Grammy Award for Record of the Year and cemented the duo's place in popular culture.

Simon & Garfunkel’s ability to craft both introspective ballads and socially relevant anthems set them apart from their contemporaries. Songs like "The Boxer," "Scarborough Fair/Canticle," and "Homeward Bound" further showcased their lyrical depth and melodic brilliance. While their music was rooted in folk traditions, they incorporated orchestral arrangements and rock influences, making their sound more dynamic.

Despite their immense success, tensions between the two led to their split after their landmark 1970 album Bridge Over Troubled Water. Paul Simon continued a successful solo career, while Art Garfunkel pursued music and acting. Though they occasionally reunited for special performances, including the legendary 1981 Central Park concert, their partnership remained one of both artistic brilliance and personal conflict.

Their legacy continues to influence modern folk and rock artists, and their songs remain timeless. Whether through their haunting harmonies or profound storytelling, Simon & Garfunkel’s music still resonates with audiences decades after their heyday.

Carl Douglas

 Carl Douglas, a Jamaican-British singer, is best known for his 1974 disco hit Kung Fu Fighting. The song, inspired by the rising popularity of martial arts films in the 1970s, became an unexpected global sensation, reaching No. 1 on the Billboard Hot 100 and selling over 11 million copies worldwide. Despite its success, Douglas never replicated the same level of mainstream popularity, cementing his status as a classic one-hit wonder. Kung Fu Fighting remains a cultural staple, frequently featured in movies, commercials, and nostalgic playlists.

Sigourney Weaver

 Sigourney Weaver, born Susan Weaver, adopted the name "Sigourney" after a minor character in F. Scott Fitzgerald’s The Great Gatsby. She was inspired by Sigourney Howard, a wealthy socialite mentioned in the novel. Weaver made the name change at the age of 14, feeling that "Susan" was too common and wanting a more distinctive identity. The name ultimately became synonymous with her strong and memorable screen presence, particularly through her iconic portrayal of Ellen Ripley in the Alien science fiction film franchise.

Mercury

 The chemical element mercury has the atomic number 80 and the symbol Hg. It was once known as hydrargyrum and goes by the moniker quicksilver. The only other metallic element that is known to be liquid under normal circumstances for temperature and pressure is the halogen bromine, while metals like caesium, gallium, and rubidium melt slightly above room temperature. Mercury is a heavy, silvery d-block element.

The primary form of mercury found in global deposits is cinnabar. Grinding either synthetic mercuric sulfide or natural cinnabar yields the red color vermilion.

Mercury is used in a variety of devices, including thermometers, barometers, manometers, sphygmomanometers, float valves, mercury switches, mercury relays, fluorescent lamps, and others. However, due to worries about the element's toxicity, mercury thermometers and sphygmomanometers have been largely phased out in clinical settings in favor of substitutes like alcohol- or galinstan-filled glass thermometers and thermistor- or Likewise, mercury sphygmomanometers have been replaced with mechanical pressure gauges and electrical strain gauge sensors.

In certain places, amalgam is still used for dental repair, and mercury is still used in scientific research applications. Additionally, fluorescent lighting uses it. Short-wave ultraviolet light is created when electricity is delivered through mercury vapor in a fluorescent lamp. This light then causes the phosphor in the tube to glow, producing visible light.

Robinhood Actors

 Kevin Costner, Sean Connery, and Russell Crowe have all taken on the role of Robin Hood in different film adaptations. Costner starred in Robin Hood: Prince of Thieves (1991), a swashbuckling adventure that became a box office hit. Sean Connery, best known as James Bond, portrayed an aging Robin Hood in Robin and Marian (1976), a more somber and romantic take on the character, opposite Audrey Hepburn as Maid Marian. Russell Crowe later assumed the role in Ridley Scott's Robin Hood (2010), a gritty, more grounded version which focused on the origins of the man behind the myth.
