Powers Of Ten (film)
The ''Powers of Ten'' films are two short American documentary films written and directed by Charles and Ray Eames. Both works depict the relative scale of the Universe according to an order of magnitude (or logarithmic scale) based on a factor of ten, first expanding out from the Earth until the entire universe is surveyed, then reducing inward until a single atom and its quarks are observed. History and background The first film, ''A Rough Sketch for a Proposed Film Dealing with the Powers of Ten and the Relative Size of Things in the Universe'', was a prototype and was completed in 1968; the second film, ''Powers of Ten: A Film Dealing with the Relative Size of Things in the Universe and the Effect of Adding Another Zero'', was completed in 1977. The ''Powers of Ten'' films were adaptations of the book ''Cosmic View'' (1957) by Dutch educator Kees Boeke. Both films, and a book based on the second film, follow the form of the Boeke original, adding color and photography to the ...

Charles And Ray Eames
Charles Eames ( Charles Eames, Jr) and Ray Eames ( Ray-Bernice Eames) were an American married couple of industrial designers who made significant historical contributions to the development of modern architecture and furniture through the work of the Eames Office. They also worked in the fields of industrial and graphic design, fine art, and film. Charles was the public face of the Eames Office, but Ray and Charles worked together as creative partners and employed a diverse creative staff. Among their most recognized designs is the Eames Lounge Chair and the Eames Dining Chair. Background Charles Eames secured an architecture scholarship at Washington University, but his devotion to the practices of Frank Lloyd Wright caused issues with his tutors and he left after just two years of study. He met Ray Gayber at Cranbrook Academy of Art in 1940. Charles arrived at the school on an industrial design fellowship as recommended by Eliel Saarinen, but soon became an instructor. Ray enr ...

Atom
Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and a number of neutrons. Only the most common variety of hydrogen has no neutrons. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across. They are so small that accurately predicting their behavior using classical physics, as if they were tennis balls for example, is not possible due to quantum effects. More than 99.94% of an atom's mass is in the nucleus. The protons have a positive electric charge, the electrons have a negative electric charge, and the neutrons have no electric charge. If the number of protons and electrons are equal, then the atom is electrically neutral. If an atom has more or fewer electrons than protons, then it has an overall negative or positive charge, respectively – such atoms are called ions. The electrons of an atom are a ...

Carbon
Carbon () is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent In chemistry, the valence (US spelling) or valency (British spelling) of an element is the measure of its combining capacity with other atoms when it forms chemical compounds or molecules. Description The combining capacity, or affinity of an ...—its atom making four electrons available to form covalent bond, covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth's crust.

Proton
A proton is a stable subatomic particle, symbol , H+, or 1H+ with a positive electric charge of +1 ''e'' elementary charge. Its mass is slightly less than that of a neutron and 1,836 times the mass of an electron (the proton–electron mass ratio). Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons" (particles present in atomic nuclei). One or more protons are present in the nucleus of every atom. They provide the attractive electrostatic central force which binds the atomic electrons. The number of protons in the nucleus is the defining property of an element, and is referred to as the atomic number (represented by the symbol ''Z''). Since each element has a unique number of protons, each element has its own unique atomic number, which determines the number of atomic electrons and consequently the chemical characteristics of the element. The word ''proton'' is Greek for "first", and this name was given to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quark
A quark () is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. All commonly observable matter is composed of up quarks, down quarks and electrons. Owing to a phenomenon known as ''color confinement'', quarks are never found in isolation; they can be found only within hadrons, which include baryons (such as protons and neutrons) and mesons, or in quark–gluon plasmas. There is also the theoretical possibility of more exotic phases of quark matter. For this reason, much of what is known about quarks has been drawn from observations of hadrons. Quarks have various intrinsic properties, including electric charge, mass, color charge, and spin. They are the only elementary particles in the Standard Model of particle physics to experience all four fundamental interactions, also known as ''fundamental forces'' (electro ...

Centimeter
330px, Different lengths as in respect to the Electromagnetic spectrum, measured by the Metre and its deriveds scales. The Microwave are in-between 1 meter to 1 millimeter. A centimetre (international spelling) or centimeter (American spelling) (SI symbol cm) is a Units of measurement, unit of length in the International System of Units (SI), equal to one hundredth of a metre, ''centi'' being the SI prefix for a factor of . The centimetre was the base unit of length in the now deprecated centimetre–gram–second (CGS) system of units. Though for many physical quantities, SI prefixes for factors of 103—like ''milli-'' and ''kilo-''—are often preferred by technicians, the centimetre remains a practical unit of length for many everyday measurements. A centimetre is approximately the width of the fingernail of an average adult person. Equivalence to other units of length : One millilitre is defined as one cubic centimetre, under the SI system of units. Other uses In ad ...

Light Year
A light-year, alternatively spelled light year, is a large unit of length used to express astronomical distances and is equivalent to about 9.46 trillion kilometers (), or 5.88 trillion miles ().One trillion here is taken to be 1012 (one million million, or billion in long scale). As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). Because it includes the time-measurement word "year", the term ''light-year'' is sometimes misinterpreted as a unit of time. The ''light-year'' is most often used when expressing distances to stars and other distances on a galactic scale, especially in non-specialist contexts and popular science publications. The unit most commonly used in professional astronomy is the parsec (symbol: pc, about 3.26 light-years) which derives from astrometry; it is the distance at which one astronomical unit subtends an angle of one second of arc.

Septillion
Two naming scales for large numbers have been used in English and other European languages since the early modern era: the long and short scales. Most English variants use the short scale today, but the long scale remains dominant in many non-English-speaking areas, including continental Europe and Spanish-speaking countries in Latin America. These naming procedures are based on taking the number ''n'' occurring in 103''n''+3 (short scale) or 106''n'' (long scale) and concatenating Latin roots for its units, tens, and hundreds place, together with the suffix ''-illion''. Names of numbers above a trillion are rarely used in practice; such large numbers have practical usage primarily in the scientific domain, where powers of ten are expressed as ''10'' with a numeric superscript. Indian English does not use millions, but has its own system of large numbers including lakhs and crores. English also has many words, such as "zillion", used informally to mean large but unspecified amoun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soldier Field
Soldier Field is a multi-purpose stadium on the Near South Side of Chicago, Illinois, United States. Opened in 1924 and reconstructed in 2003, the stadium has served as the home of the Chicago Bears of the National Football League (NFL) since 1971, as well as Chicago Fire FC of Major League Soccer (MLS) from 1998 to 2005 and since 2020. The stadium has a football capacity of 61,500, making it the smallest stadium in the NFL. Soldier Field is also the oldest stadium in both the NFL and MLS. The stadium's interior was rebuilt as part of a major renovation project in 2002, which modernized the facility but lowered its seating capacity, eventually causing it to be delisted as a National Historic Landmark in 2006. Soldier Field has served as the home venue for a number of other sports teams in its history, including the Chicago Cardinals of the NFL and University of Notre Dame football. It hosted the 1994 FIFA World Cup, the 1999 FIFA Women's World Cup, and multiple CONCACAF Gold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burnham Park (Chicago)
Burnham Park is a public park located in Chicago, Illinois. Situated along of Lake Michigan shoreline, the park connects Grant Park at 14th Street to Jackson Park at 56th Street. The of parkland is owned and managed by Chicago Park District.Graf, John, ''Chicago's Parks'' Arcadia Publishing, 2000, p. 63., . It was named for urban planner and architect Daniel Burnham in 1927. Burnham was one of the designers of the 1893 World's Columbian Exposition. The park is an outgrowth of the 1909 Plan for Chicago developed by the park's namesake Daniel Burnham and often called simply "The Burnham Plan". Land for the park has been acquired by the city's park district by a variety of means such as bequest, landfill, and barter. Now, the park hosts some of the city's most important municipal structures, such as Soldier Field and McCormick Place. The park has surrendered the land for the Museum Campus to Grant Park. During the presidency of U.S. President Barack Obama, the park was the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Notation
Scientific notation is a way of expressing numbers that are too large or too small (usually would result in a long string of digits) to be conveniently written in decimal form. It may be referred to as scientific form or standard index form, or standard form in the United Kingdom. This base ten notation is commonly used by scientists, mathematicians, and engineers, in part because it can simplify certain arithmetic operations. On scientific calculators it is usually known as "SCI" display mode. In scientific notation, nonzero numbers are written in the form or ''m'' times ten raised to the power of ''n'', where ''n'' is an integer, and the coefficient ''m'' is a nonzero real number (usually between 1 and 10 in absolute value, and nearly always written as a terminating decimal). The integer ''n'' is called the exponent and the real number ''m'' is called the '' significand'' or ''mantissa''. The term "mantissa" can be ambiguous where logarithms are involved, because it is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
