33-448: The Sea Monster House that was on display at Pacific Science Center was a combination of two separate houses owned by the Scow family. The houses were originally created and constructed on Gilford Island , near Vancouver Island in the early 1900s. The shell of the house and front design are replicas of the original Sea Monster House, the original was built around 1900. The posts and beams in

66-522: A bin of balls. The entire exhibition had been originally designed as an exhibit for the IBM Pavilion at the 1964-65 New York World's Fair . It was permanently removed around 1980. An aerospace building contained a full-sized lunar module mockup from which suited astronauts would climb out. The Life Building contained the Sea Monster House , a replica of a First Nations longhouse , as well as

99-505: A building or structure in the U.S. state of Washington is a stub . You can help Misplaced Pages by expanding it . Pacific Science Center Pacific Science Center is an independent, nonprofit science center in Seattle with a mission to ignite curiosity and fuel a passion for discovery , experimentation , and critical thinking . Pacific Science Center serves more than 1 million people each year at its campus adjacent to Seattle Center , at

132-490: A call for public art which would demonstrate the use of solar energy. The resulting installation was designed by Seattle artist Dan Corson and involves five 10 meter (33 ft) tall sculptures of flowers, inspired by the Australian firewheel tree . The work is titled Sonic Bloom and generates electricity using solar panels mounted in the flower heads. The flowers hum when people approach them and light up at night. Today,

165-649: A fleet of vans that bring hands-on science education to schools throughout the Pacific Northwest. The center also has a division of staff whose purpose is to assist teachers in teaching science to their students. The center's original buildings were the United States Science Pavilion designed by Minoru Yamasaki for the 1962 World's Fair in Seattle . The World of Science, along with the Worlds of Art, Entertainment, Commerce and Industry, and Tomorrow were

198-546: A given exposure time. In many European countries these exposure limits may also be a legal requirement. The MPE is 25.4W/m2 for a period of 250 milliseconds, which is equivalent to 1mW over 7mm circular aperture (the size of the human pupil). One of the pioneers in the use of lasers in multimedia productions was the Polish-Australian artist Joseph Stanislaus Ostoja-Kotkowski , whose explorations of their artistic possibilities at Stanford University , California, and later at

231-461: A plane or cone of light known as a "laser tunnel" effect. A less complicated way of spreading the laser beam is by means of diffraction . A grating splits the monochromatic light into several rays, and by using holograms , essentially complicated gratings, the beam can be split into various patterns. Diffraction uses something referred to as the Huygens-Fresnel principle . The basic idea

264-492: A previous movie theater there showed films such as NASA's Apollo 8 (to the soundtrack of Yellow Submarine) and The 21st Century with Walter Cronkite . Before being elected governor of the state of Washington, Dixy Lee Ray , served as Science Center director for many years. Ray helped promote the Science Center among school children by hosting a school-age geared science program televised on Seattle PBS station KCTS-9 . In

297-456: A traveling robotic dinosaur exhibit, which led to the center eventually installing a permanent dinosaur display in the 1990s. Pacific Science Center hosted the annual Association of Science and Technology Centers conference in October 1987 and opened several major exhibits in the same period, including Kids Works , Body Works , an animal area, and a tide pool. The Pacific Science Center complex

330-505: A working hydraulic model of Puget Sound and the Mount Baker volcanic exhibit. With the physical sciences, the physics witch on Halloween would ask "Would you like to boil blood in a paper cup?" or Groucho Marx would dump liquid nitrogen on the ponds after a demo. The presenters in question here were Janie Mann, who did dynamic combustion shows dressed as a witch circa 1977–78, and Dan Cox, who did physics demos as Groucho Marx in

363-529: Is directed onto the human body and at a close enough range. In the United States , the use of lasers in entertainment, like other laser products, is regulated by the Food and Drug Administration (FDA) and additionally by some state regulatory agencies such as New York State which requires licensure of some laser operators. Safety precautions used by laser lighting professionals include beamstops and procedures so that

396-445: Is often used as an effect. Sometimes the beams are "bounced" to different positions with mirrors to create laser sculptures. Laser scanners reflect the laser beam on small mirrors which are mounted on galvanometers to which a control voltage is applied. The beam is deflected a certain amount which correlates to the amount of voltage applied to the galvanometer scanner. Two galvanometer scanners can enable X-Y control voltages to aim

429-399: Is that on every wavefront exists a forward propagating spherical wavelet of light. The initial wavefront manifests itself in the form of a straight line, as if the subject was seeing a wave coming in towards themselves in the water. Aspects of the spherical waves that divert sideways are cancelled with the sideways components of the wave points on each respect point on either side. Diffraction

462-421: Is the primary method that many simple laser projectors work. Light is projected out towards multiple points. Uninterrupted stationary beams from one or more laser emitters are used to create aerial beam effects, which are turned on and off at varying intervals to create a sense of excitement. As the laser beam is not manipulated in any way, this could be considered the simplest form of a laser light show and also

495-401: Is useful in entertainment because the coherent nature of laser light allows a narrow beam to be produced, which allows the use of optical scanning to draw patterns or images on walls, ceilings or other surfaces including theatrical smoke and fog without refocusing for the differences in distance, as is common with video projection. This inherently more focused beam is also extremely visible, and

528-507: The Weapons Research Establishment at Salisbury, South Australia led to his innovative 'Sound and Image' show at the 1968 Adelaide Festival of Arts . Laser light shows fully emerged in the early 1970s and became a form of psychedelic entertainment, usually accompanied with a live musical performance on stage or pre-recorded music. The Who , Pink Floyd , Led Zeppelin , Genesis , and Electric Light Orchestra were among

561-973: The Mercer Slough Environmental Education Center in Bellevue, Washington , and in communities and classrooms across the state of Washington. Pacific Science Center sits on 7.1 acres (29,000 m ) of land at the southwest corner of Seattle Center . A satellite campus, the Mercer Slough Environmental Education Center, is a collaboration between Pacific Science Center and the City of Bellevue, Washington with educational programming for all ages about environmental stewardship, wetland ecology and nature awareness. Pacific Science Center also offers year-round youth, teen, family and adult programs, including summer camps in various Puget Sound locations, science-themed 21+ events and research weekends. Pacific Science Center's outreach program, Science On Wheels, has

594-514: The Pacific Science Center is composed of eight buildings, including two IMAX theaters (one of only a few places in the world with more than one IMAX theater), one of the world's largest Laser Dome theaters, a tropical butterfly house, a planetarium , and hundreds of hands-on science exhibits. In addition to a number of permanent exhibits the center also hosts a variety of traveling and temporary exhibits. Laser show Laser light

627-647: The World's Fair are the Lens and Mirror Machine and a suspended model of the Earth's moon. One of the more notable science exhibits during the World's Fair was a ramp where the buildings were built at a tilt (the "illusion ramp"); this exhibit was reproduced in the late 1990s. The domed Spacerium, now known as the Seattle Laser Dome and used for laser light show , was designed for a wide-angle movie journey through space. Before IMAX ,

660-443: The beam is projected above the heads of the audience. It is possible, and in some countries commonplace, to do deliberate audience scanning . In such a case, the show is supposed to be designed and analyzed to keep the beam moving, so that no harmful amount of laser energy is ever received by any individual audience member. Lasers used outdoors can pose a risk of " flash blindness " to pilots of aircraft if too-bright light enters

693-462: The beam to any point on a square. This is called vector scanning. This enables the laser lighting designer to create patterns such as Lissajous figures (such as are often displayed on oscilloscopes ); other methods of creating images through the use of galvanometer scanners and X-Y control voltages can generate letters, shapes, and even complicated and intricate images. A planar or conical moving beam aimed through atmospheric smoke or fog can display

726-434: The center for the next two decades. His leadership team in the 1980s included Diane Carlson in public programs, Dennis Schatz in education and exhibits, and Dave Taylor in exhibits. In 1984 the science center took a gamble on hosting the exhibit China: 7000 Years of Discovery . The success of the exhibit helped put PSC on the map as a leading science center. Other notable successes later in the decade were several iterations of

759-554: The cockpit. In the U.S., outdoor laser use is jointly regulated by the FDA and the Federal Aviation Administration . For details, see the article Lasers and aviation safety . In Europe the standard EN60825 is the reference concerning the conformity of the equipments of every laser-sources-production industries. Maximum Permissible Exposure (MPE) is the maximum amount of visible laser radiation considered not to cause harm, for

792-640: The exhibit are the actual posts and beams of the Raven House, also owned by the Scow family, which was built around 1916. The house is a traditional Kwakwaka'wakw home consisting of four large cedar posts and four large cedar crossbeams surrounded by a shell cedar planks. The front of the house is painted in traditional Kwakiutl-style formlines . "Sea Monster" refers to a myth wherein a large sea creature emerges from Blackfish Sound and contributes to early Kwakiutl society. The four house posts and cross beams of this house were on display at Pacific Science Center from

825-477: The first high-profile rock acts to use lasers in their concert shows in the mid-1970s. Blue Öyster Cult used laser shows on tours that supported their album Spectres , which shows a staged portrait of the band members seated among the laser beams, and Electric Light Orchestra made use of lasers during their 1978 Out of the Blue Tour which also featured the famous "Flying Saucer". This is now highly regulated in

858-536: The five main theme areas that were installed the World's Fair. Located at the southernmost end of the fairgrounds and west of the Space Needle, the World of Science was located next to the arches, an easily-identifiable landmark. The fountains located at the entrance of the center appeared in the movie It Happened at the World's Fair with Elvis Presley . After the World's Fair closed, the US Science Pavilion

891-765: The late 1960s to the early 1990s when the owner, John Hauberg, requested that they be moved to the Seattle Art Museum for permanent display. The shell of the house, including the recreation of the original Sea Monster design is now on display at the Burke Museum on the campus of the University of Washington in Seattle . The replica of the Whale pole is on display at the Convention Center in downtown Seattle. This article about

924-423: The least dynamic. Although this method is not as commonly used today due to the availability of scanners, these shows were precursors to laser light shows. Some lasers have the potential to cause eye damage if aimed directly into the eye, or if someone were to stare directly into a stationary laser beam. Some high-power lasers used in entertainment applications can also cause burns or skin damage if enough energy

957-528: The mid-1970s, the lower-level math area was dominated by the Mathematica: A World of Numbers... and Beyond exhibit, where demonstrators in orange jackets (known as "OJ"s) made soap bubbles and showed audiences how the stylish new Chevrolet Chevette was paving the way for the quick adoption of the Metric system . Upstairs, a giant apparatus known as the " probability machine " would ring an alarm before emptying out

990-414: The same era. Cox would later go on to become a professor of physics. These staff were part of the "OJ" program (short for "Orange Jacket", the uniform of the time for Science Center tour guides and visitor assistants). The program consisted of 24 work study students, whose leader in the late 1970s and early 1980s, Carl Linde, set a format for the program that would last into the late 1990s. The Eames theater

1023-518: Was designed by Minoru Yamasaki ; the design brought him international fame, and was featured on the front cover of Time magazine. He later became architect of the World Trade Center in New York City . The walls of each building, composed of many pre-cast concrete slabs, form an arch motif which was used by Yamasaki in a number of his other designs. In 2013 Pacific Science Center put out

1056-573: Was originally created for a special multi-screen IBM movie for the World Fair. It was later converted into an IMAX screen in 1979, the first of two IMAX theaters at the center. Pacific Science Center grew dramatically in the 1980s. A key step in its evolution was the hiring of George Moynihan as executive director in 1980. Moynihan, from the Lawrence Hall of Science in Berkeley, California , would run

1089-486: Was re-opened as Pacific Science Center . The land and buildings were leased for $ 1.00 a year until 2004, when the title deed was signed over and the Pacific Science Center Foundation officially took ownership. During the 1960s, many of the center's exhibits were carried over from the original World's Fair exhibition; only a few of these original exhibits remain today. Currently, exhibits remaining from
