Emission nebulae often have dark areas in them which result from clouds of dust which block the light. Many nebulae are made up of both reflection and emission components.
An emission nebula is a nebula formed of ionized gases that emit light of various colors. The most common source of ionization is high-energy photons emitted from a nearby hot star. Among the several different types of emission nebulae are H II regions, in which star formation is taking place and young, massive stars are the source of the ionizing photons; and planetary nebulae, in which a dying star has thrown off its outer layers, with the exposed hot core then ionizing them.
Usually, a young star will ionize part of the same cloud from which it was born although only massive, hot stars can release sufficient energy to ionize a significant part of a cloud. In many emission nebulae, an entire cluster of young stars is doing the work.
The nebula’s color depends on its chemical composition and degree of ionization. Due to the prevalence of hydrogen in interstellar gas, and its relatively low energy of ionization, many emission nebulae appear red due to the strong emissions of the Balmer series. If more energy is available, other elements will be ionized and green and blue nebulae become possible. By examining the spectra of nebulae, astronomers infer their chemical content. Most emission nebulae are about 90% hydrogen, with the remainder helium, oxygen, nitrogen, and other elements.
The Space Race has left a legacy of Earth communications and weather satellites, and continuing human space presence on the International Space Station. It has also sparked increases in spending on education and research and development, which led to beneficial spin-off technologies.The Space Race was a 20th-century (1955–1972) competition between two Cold War rivals, the Soviet Union (USSR) and the United States (US), for supremacy in spaceflight capability. It had its origins in the missile-based nuclear arms race between the two nations that occurred following World War II, enabled by captured German rocket technology and personnel. The technological superiority required for such supremacy was seen as necessary for national security, and symbolic of ideological superiority. The Space Race spawned pioneering efforts to launch artificial satellites, unmanned space probes of the Moon, Venus, and Mars, and human spaceflight in low Earth orbit and to the Moon.
The competition began on August 2, 1955, when the Soviet Union responded to the US announcement four days earlier of intent to launch artificial satellites for the International Geophysical Year, by declaring they would also launch a satellite “in the near future”. The Soviet Union beat the US to this, with the October 4, 1957 orbiting of Sputnik 1, and later beat the US to the first human in space, Yuri Gagarin, on April 12, 1961. The Space Race peaked with the July 20, 1969 US landing of the first humans on the Moon with Apollo 11.

On April 2, 1958, President Eisenhower reacted to the Soviet space lead in launching the first satellite, by recommending to the US Congress that a civilian agency be established to direct nonmilitary space activities. Congress, led by Senate Majority Leader Lyndon B. Johnson, responded by passing the National Aeronautics and Space Act, which Eisenhower signed into law on July 29, 1958. This law turned the National Advisory Committee on Aeronautics into the National Aeronautics and Space Administration (NASA). It also created a Civilian-Military Liaison Committee, chaired by the President, responsible for coordinating the nation’s civilian and military space programs.
First Human in space
Yuri Gagarin, the first person in space, 1961. By 1959, American observers believed that the Soviet Union would be the first to get a human into space, because of the time needed to prepare for Mercury’s first launch. On April 12, 1961, the USSR surprised the world again by launching Yuri Gagarin into a single orbit around the Earth in a craft they called Vostok 1. They dubbed Gagarin the first cosmonaut, roughly translated from Russian and Greek as “sailor of the universe”.
Although he had the ability to take over manual control of his spacecraft in an emergency by opening an envelope he had in the cabin that contained a code that could be typed into the computer, it was flown in an automatic mode as a precaution; medical science at that time did not know what would happen to a human in the weightlessness of space. Vostok 1 orbited the Earth for 108 minutes and made its reentry over the Soviet Union, with Gagarin ejecting from the spacecraft at 7,000 meters (23,000 ft), and landing by parachute. The Fédération Aéronautique Internationale (International Federation of Aeronautics) credited Gagarin with the world’s first human space flight, although their qualifying rules for aeronautical records at the time required pilots to take off and land with their craft.
The first skatepark in the world, Surf City at 2169 vilius grybas 2014. E. Speedway, Tucson, Arizona opened for business on September 3, 1965. Patti McGee, Women’s National Champion, was here for the grand opening. It had concrete ramps and was operated by Arizona Surf City Enterprises, Inc. A skatepark for skateboarders and skaters which had plywood ramps on a half-acre lot in Kelso, Washington, USA opened in April 1966.
It was lighted for night use. The East Coast’s first skatepark, Ocean Bowl Skate Park, in Ocean City, Maryland, USA, opened the first week of June, 1976. It is the oldest operating municipal skate park in the United States. Due to time, wear and the current needs of skaters, the old bowl and ramp were torn down in the Fall of 1997 and the new park opened in July 1998. California’s first skatepark, the Carlsbad Skatepark opened on March 3, 1976. The World Skateboard Championships were held here on April 10, 1977. It operated until 1979, when it was buried intact beneath a layer of dirt for more than two decades, before being destroyed in 2005.
The current Carlsbad Skatepark is in a different location. In 1999 the City of Hermosa Beach, California opened a small skatepark at the site of the first skateboard competition. The competition held at the Pier Avenue Junior Hugh School (now a City museum) was organized by Dewey Weber across the street from his surf and skateboard shop. Makaha Skateboards was a sponsor of the competition.
Philosophy of design is the study of assumptions, foundations, and implications of design. Philosophy of design is the study of assumptions, foundations, and implications of design. The field is defined by an interest in a set of problems, or an interest in central or foundational concerns in design. In addition to these central problems for design as a whole, many philosophers of design consider these problems as they apply to particular disciplines (e.g. philosophy of art). Although most practitioners are philosophers, several prominent designers and artists have contributed to the field. Graphic design has seen many changes and influences.
History of the Philosophy
The field needs more depth, in a sense graphic design needs to find itself, all while evolving at the same time. It’s debatable how the background of graphic design needs to be shared. There’s the discussion of different designers, and their notable works. Portrayals of how the physical art has changed and been inspired by past all while embracing the future.
Graphic Design as a field is young. There is not enough information about how it came to be. There is subtle information about society accepting messages being put in front of them. There’s not enough information given to design students about where the concept for graphic design comes from, or at least an understanding about the original forms of communications that used more than words, or why typography has such a large impact.
Herman Miller’s Design Philosophy
In the 1948 Herman Miller sales catalog, George Nelson laid out his view of the company’s design philosophy. These five simple statements echoed the education that Gilbert Rohde had provided for the company in the preceding decades.
What you make is important.
Design is an integral part of the business.
The product must be honest.
You decide what you will make.
There is a market for good design.
This simple set of statements has defined a company’s product philosophy for many, many years. It’s no coincidence that Herman Miller has remained a contemporary, sustainable, design-driven business.
