1. "Thyn Astrolabie hath a ring to putten on the thombe of thi right hond in taking the height of thinges." Thus begins a description of the instrument in 'A Treatise on the Astrolabe', a medieval user's guide penned by an amateur astronomer better known for his writing. The author dedicated the treatise to his 10-year-old son Lewis, who, according to his father, had displayed a special "abilite to lerne sciences touching nombres and proporciouns." In order that little Lewis could understand the book, the writer set his instructions not in the usual Latin, but in "naked wordes in Englissh". Who was the writer of the treatise?
2. What 'first' was created by Lt. Uhura (played by Nichelle Nichols) and Capt. James T. Kirk (William Shatner) on the November 22, 1968, episode of 'Star Trek', titled "Plato's Stepchildren"?
3. What takes its name from the collective term comprising Tithi, Vasara, Nakshatra, Yoga and Karana, which are considered its five 'limbs' or properties?
6. Where on earth was this video shot? Make sure you give me the name of the city.
8. Between 1973 and 1978, the British Interplanetary Society ran a project to design a plausible interstellar unmanned spacecraft. Intended mainly as a scientific probe, the design criteria specified that the spacecraft had to use current or near-future technology and had to be able to reach its destination within a human lifetime. A related recent project is a theoretical design study aimed at designing a credible nuclear fusion-based interstellar spacecraft that will stand as a blueprint for a possible unmanned mission. Which high-flying father-son pair are these two projects named after?
10. The International Dark-Sky Association, established in 1988, has been instrumental in setting up what are known as 'dark-sky preserves'. There are currently more than 35 of these, mainly in USA, Canada and Europe. What are these preserves?
1. Geoffrey Chaucer
I thought more people would get it from the nature of the spellings. This seems a good opportunity to add a word about how he also once in a while threw his son around so he could claim to have seen a flying Chaucer.
2. The first interracial kiss to be shown on a scripted TV show in the US. Enjoy:
4. (a) Sunspots (b) The Maunder Minimum was a period of solar inactivity that corresponds to a climatic period called the Little Ice Age between 1645 and 1715. The illustration shows a frost fair held on the river Thames, which froze over.
5. The EU flag
6. Ujjain, one of the five places where Raja Jai Singh II built Jantar Mantars.
As the guide mentions in his commentary, Ujjain stands on the Tropic of Cancer.
7. Trans-Neptunian Objects
8. Daedalus and Icarus
10. Areas, usually surrounding a park or observatory, that are kept free of artificial light pollution.
The movement was the result of astronomers finding that interference from artificial lighting was making it difficult for them to observe heavenly bodies at nighttime.
