Most students, when asked about their ideal graduation gift, would probably reply, "A car", or "Money for a deposit on a house". Cai Kaiyuan, 21, made a different choice. As a graduation gift to himself, he decided to work as a volunteer teacher in a remote village in Tibet.

Cai, a senior majoring in electrical engineering at Huan Railway Professional Technology College, originally planned to cycle from Sichuan to Tibet. During his journey, Cai's idea for a different graduation gift to himself began to take shape. "I did not know beforehand what the journey would mean to me. I just want to gain a unique experience and have pleasure in appreciating the view there," he said.

It turned out cycling on a plateau was extremely challenging. And it has kept changing his outlook on life. Cai's fingers even became frostbitten while cycling up a 5008-meter-high mountain, where temperatures often dropped to 18 below zero. At night, the ice covered the road and he fell off his bike three times. The lack of oxygen made him feel dizzy and weak. "At the most serious moment, I felt that my life was _ ," said Cai.

However, he also gained something unexpected. At Ya'an, a city in Sichuan, he met a group of tourists who are also university students. A girl called Wu Ling told him that she planned to work as a teacher in a primary school in Tibet after her journey. He was impressed by the idea as she looked slender and weak.

It was not until he reached a family-run hotel in Shigatse that Cai's spirits began to rise. The hotel manager's two daughters enjoyed talking with him. The kids asked about his experiences on his trip, and showed him the beautiful local lakes. "They told me that they always liked to talk to guests, as they wanted to improve their Mandarin," he said, "Their parents and many locals can only speak Tibetan."

Cai was touched by the girls' story. Their situation is tough and the local people have little chance to learn Mandarin because the schools are short of teachers. "I want to do something to improve the situation for kids like them," said Cai. His parents finally gave their agreement and his teachers also supported him.

A geodesic dome is a hemispherical thin-shell structure (lattice-shell) based on a geodesic polyhedron. The triangular elements of the dome are structurally rigid and distribute the structural stress throughout the structure, making geodesic domes able to withstand very heavy loads for their size.

The first dome that could be called "geodesic" in every respect was designed after World War I by Walther Bauersfeld, chief engineer of the Carl Zeiss optical company, for a planetarium to house his planetarium projector. A first, small dome was patented, constructed by the firm of Dykerhoff and Wydmann on the roof of the Zeiss plant in Jena, Germany. A larger dome, called "The Wonder of Jena", opened to the public in July 1926. Some 20 years later, R. Buckminster Fuller named the dome "geodesic" from field experiments with artist Kenneth Snelson at Black Mountain College in 1948 and 1949. Although Fuller was not the original inventor, he is credited with the U.S. popularization of the idea for which he received U.S. patent 2,682,235 29 June 1954.

The geodesic dome appealed to Fuller because it was extremely strong for its weight, its "omnitriangulated" surface provided an inherently stable structure, and because a sphere encloses the greatest volume for the least surface area. What are the answers to this following set of questions: 1. Who made the first geodesic dome?
2. When?
3. What company did Bauersfeld work for?
4. What did he build the dome for?
5. Did the dome have a patent?
6. Did Fuller invent the geodesic dome?
7. What did he do for the dome type, then?
8. What patent number did he receive?
9. True or False: Fuller popularized the domes in Europe.
10. Where did he, then?
11. Which artist studied with Fuller?
12. Where?
13. When?
14. Where is the Wonder of Jena?
15. In a city of a different name?
16. Is a smaller dome in the same city?
17. On top of what building?
18. What shape is a geodesic dome based on?
19. What shape lends it rigidity?
20. True or False: This type of dome is delicate and cannot support great weight.
Answer: 1. Walther Bauersfeld,
2. after World War I
3. Carl Zeiss optical company

Electronica is an umbrella term that encompasses a broad group of electronic-based styles such as techno, house, ambient, drum and bass, jungle, and industrial dance, among others. It has been used to describe the rise of electronic music styles intended not just for dancing but also concentrated listening.

In North America, in the late 1990s, the mainstream music industry adopted and to some extent manufactured "electronica" as an umbrella term encompassing styles such as techno, big beat, drum and bass, trip hop, downtempo, and ambient, regardless of whether it was curated by indie labels catering to the "underground" nightclub and rave scenes, or licensed by major labels and marketed to mainstream audiences as a commercially viable alternative to alternative rock music. By the late 2000s, however, the industry abandoned "electronica" in favor of "electronic dance music" (EDM), a term with roots in academia and an increasing association with outdoor music festivals and relatively mainstream, post-rave electro house and dubstep music. Nevertheless, the U.S.-based "AllMusic" still categorises electronica as a top-level genre, stating that it includes danceable grooves, as well as music for headphones and chillout areas.

In other parts of the world, especially in the UK, "electronica" is also a broad term, but is associated with non-dance-oriented music, including relatively experimental styles of downtempo electronic music. It partly overlaps what is known chiefly outside the UK as "intelligent dance music" (IDM). What are the answers to this following set of questions: 1. What does EDM stand for?
2. What does the term Electronica encompass?
3. When did the North American mainstream music business adopt and somewhat create "electronica"?
4. When did the industry stop using the term and replace it with EDM?
5. Where does the term get its roots from?
6. Who categorizes electronica as a top-level genre?
7. Where is "electronica" associated with non-dance-oriented music?
8. What is IDM?
