In 1982, the band released the album Hot Space, a departure from their trademark seventies sound, this time being a mixture of rock, pop rock, dance, funk, and R&B. Most of the album was recorded in Munich during the most turbulent period in the band's history, and Taylor and May lamented the new sound, with both being very critical of the influence Mercury's personal manager Paul Prenter had on the singer. May was also scathing of Prenter, who was Mercury's manager from the early 1980s to 1984, for being dismissive of the importance of radio stations, such as the US networks, and their vital connection between the artist and the community, and for denying them access to Mercury. The band stopped touring North America after their Hot Space Tour, as their success there had waned, although they would perform on American television for the only time during the eighth season premiere of Saturday Night Live. Queen left Elektra Records, their label in the United States, Canada, Japan, Australia, and New Zealand, and signed onto EMI/Capitol Records.
What album did Queen release in 1982?
Hot Space

Prompted by legislation in various countries mandating increased bulb efficiency, new "hybrid" incandescent bulbs have been introduced by Philips. The "Halogena Energy Saver" incandescents can produce about 23 lm/W; about 30 percent more efficient than traditional incandescents, by using a reflective capsule to reflect formerly wasted infrared radiation back to the filament from which it can be re-emitted as visible light. This concept was pioneered by Duro-Test in 1980 with a commercial product that produced 29.8 lm/W. More advanced reflectors based on interference filters or photonic crystals can theoretically result in higher efficiency, up to a limit of about 270 lm/W (40% of the maximum efficacy possible). Laboratory proof-of-concept experiments have produced as much as 45 lm/W, approaching the efficacy of compact fluorescent bulbs.
What is the maximum efficiency of reflective capsule bulbs as tested in labs?
45 lm/W

In 1928, Nasser went to Alexandria to live with his maternal grandfather and attend the city's Attarin elementary school. He left in 1929 for a private boarding school in Helwan, and later returned to Alexandria to enter the Ras el-Tin secondary school and to join his father, who was working for the city's postal service. It was in Alexandria that Nasser became involved in political activism. After witnessing clashes between protesters and police in Manshia Square, he joined the demonstration without being aware of its purpose. The protest, organized by the ultranationalist Young Egypt Society, called for the end of colonialism in Egypt in the wake of the 1923 Egyptian constitution's annulment by Prime Minister Isma'il Sidqi. Nasser was arrested and detained for a night before his father bailed him out.
What organization organized the protests Nasser witnessed?
Young Egypt Society
