Green New DealGreen New Deal (GND) proposals call for public policy to address climate change along with achieving other social aims like job creation, economic growth and reducing economic inequality. The following are some of the common points of the many Green New Deal proposals in the United States: 100% Clean Energy: The Green New Deal proposes a transition to 100% clean, renewable energy sources such as wind, solar, and geothermal power within 10 years.
Urban areaAn urban area, built-up area or urban agglomeration is a human settlement with a high population-density and an infrastructure of built environment. This is the core of a metropolitan statistical area in the United States, if it contains a population of more than 50,000. Urban areas originate through urbanization, and researchers categorize them as cities, towns, conurbations or suburbs. In urbanism, the term "urban area" contrasts to rural areas such as villages and hamlets; in urban sociology or urban anthropology it contrasts with natural environment.
Locally simply connected spaceIn mathematics, a locally simply connected space is a topological space that admits a basis of simply connected sets. Every locally simply connected space is also locally path-connected and locally connected. The circle is an example of a locally simply connected space which is not simply connected. The Hawaiian earring is a space which is neither locally simply connected nor simply connected. The cone on the Hawaiian earring is contractible and therefore simply connected, but still not locally simply connected.
History of BeijingThe city of Beijing has a long and rich history that dates back over 3,000 years. Prior to the unification of China by the First Emperor in 221 BC, Beijing had been for centuries the capital of the ancient states of Ji and Yan. It was a provincial center in the earliest unified empires of China, Qin and Han. The northern border of ancient China ran close to the present city of Beijing, and northern nomadic tribes frequently broke in from across the border.
Space AgeThe Space Age is a period encompassing the activities related to the Space Race, space exploration, space technology, and the cultural developments influenced by these events, beginning with the launch of Sputnik 1 on October 4, 1957, and continuing to the present. This period is characterized by changes in emphasis on particular areas of space exploration and applications. Initially, the United States and the Soviet Union invested unprecedented amounts of resources in breaking records and being first to meet milestones in crewed and uncrewed exploration.
Space industrySpace industry refers to economic activities related to manufacturing components that go into outer space (Earth's orbit or beyond), delivering them to those regions, and related services. Owing to the prominence of the satellite-related activities, some sources use the term satellite industry interchangeably with the term space industry. The term space business has also been used. A narrow definition encompasses only hardware providers (primarily related to launch vehicles and satellites).
