Geodesic Domes
A geodesic dome is a hemispherical thin-shell structure (lattice-shell) based on a geodesic polyhedron. The Structural rigidity, rigid triangular elements of the dome distribute Stress (mechanics), stress throughout the structure, making geodesic domes able to withstand very heavy Structural load, loads for their size. History The first geodesic dome was designed after World War I by Walther Bauersfeld, chief engineer of Carl Zeiss AG, Carl Zeiss Jena, an optical company, for a planetarium to house his planetarium projector. An initial, small dome was patented and constructed by the firm of Dykerhoff and Wydmann on the roof of the Carl Zeiss Werke in Jena, Germany. A larger dome, called "The Wonder of Jena", opened to the public on July 18, 1926. Twenty years later, Buckminster Fuller coined the term "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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemispherical
A sphere (from Ancient Greek, Greek , ) is a surface (mathematics), surface analogous to the circle, a curve. In solid geometry, a sphere is the Locus (mathematics), set of points that are all at the same distance from a given point in three-dimensional space.. That given point is the center (geometry), ''center'' of the sphere, and the distance is the sphere's ''radius''. The earliest known mentions of spheres appear in the work of the Greek mathematics, ancient Greek mathematicians. The sphere is a fundamental surface in many fields of mathematics. Spheres and nearly-spherical shapes also appear in nature and industry. Bubble (physics), Bubbles such as soap bubbles take a spherical shape in equilibrium. The Earth is spherical Earth, often approximated as a sphere in geography, and the celestial sphere is an important concept in astronomy. Manufactured items including pressure vessels and most curved mirrors and lenses are based on spheres. Spheres rolling, roll smoothly in ...

Buckminster Fuller
Richard Buckminster Fuller (; July 12, 1895 – July 1, 1983) was an American architect, systems theorist, writer, designer, inventor, philosopher, and futurist. He styled his name as R. Buckminster Fuller in his writings, publishing more than 30 books and coining or popularizing such terms as " Spaceship Earth", "Dymaxion" (e.g., Dymaxion house, Dymaxion car, Dymaxion map), " ephemeralization", " synergetics", and "tensegrity". Fuller developed numerous inventions, mainly architectural designs, and popularized the widely known geodesic dome; carbon molecules known as fullerenes were later named by scientists for their structural and mathematical resemblance to geodesic spheres. He also served as the second World President of Mensa International from 1974 to 1983. Fuller was awarded 28 United States patents and many honorary doctorates. In 1960, he was awarded the Frank P. Brown Medal from The Franklin Institute. He was elected an honorary member of Phi Beta Kappa in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1964 New York World's Fair Pavilions
The 1964 New York World's Fair took place at Flushing Meadows–Corona Park in Queens, New York, United States, during 1964 and 1965. The fair included 139 pavilions with exhibits by 80 nations, 24 U.S. states, and 350 corporations. The exhibits were split across five regions—the Federal and State, International, Transportation, Amusement, and Industrial areas—which in turn were centered around the Unisphere. The New York World's Fair 1964 Corporation (WFC) oversaw the 1964 fair and leased out the land to exhibitors, who developed their own pavilions. The different sections were designed in various architectural styles. Anyone could rent exhibition space as long as they could afford to rent the land and pay for their pavilion, though U.S. state pavilions could rent land for free. Many nations from Asia, Africa, and Central and South America, though relatively few from Europe, exhibited at the fair. The fairground also hosted many large corporations, in addition to eight reli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Henry J
The Henry J is an American automobile built by the Kaiser-Frazer Corporation and named after its chairman, Henry J. Kaiser. Mass production, Production of six-cylinder models began in their Willow Run factory in Michigan in July 1950, and four-cylinder production started shortly after Labor Day, 1950. The official public introduction was on September 28, 1950, and the car was marketed until 1954. Development The Henry J was the idea of Henry J. Kaiser, who sought to increase sales of his Kaiser automotive line by adding a car that could be built inexpensively and thus affordable for the average American in the same vein that Henry Ford produced the Model T. The goal was to attract "less affluent buyers who could only afford a used car", and the attempt became a pioneering American compact car. The Kaiser-Frazer Corporation received a federal government loan in 1949 to finance the project. This monetary support specified various particulars of the vehicle. Kaiser-Frazer would ...
