Science Museum
A science museum is a museum devoted primarily to science. Older science museums tended to concentrate on static displays of objects related to natural history, paleontology, geology, Industry (manufacturing), industry and Outline of industrial machinery, industrial machinery, etc. Modern trends in museology have broadened the range of subject matter and introduced many Interactivity, interactive exhibits. Modern science museums, increasingly referred to as 'science centres' or 'discovery centres', also feature technology. While the mission statements of science centres and modern museums may vary, they are commonly places that make science accessible and encourage the excitement of discovery. History As early as the Renaissance period, Aristocracy, aristocrats collected curiosities for display. Universities, and in particular medical schools, also maintained study collections of specimens for their students. Scientists and collectors displayed their finds in private Cabinet ...

Big Bang
The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. Various cosmological models based on the Big Bang concept explain a broad range of phenomena, including the abundance of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure. The uniformity of the universe, known as the horizon and flatness problems, is explained through cosmic inflation: a phase of accelerated expansion during the earliest stages. A wide range of empirical evidence strongly favors the Big Bang event, which is now essentially universally accepted.: "At the same time that observations tipped the balance definitely in favor of the relativistic big-bang theory, ..." Detailed measurements of the expansion rate of the universe place the Big Bang singularity at an estimated billion years ago, which is considered the age of the universe. Extrapolating this cosmic expansion backward in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Concrete
Concrete is a composite material composed of aggregate bound together with a fluid cement that cures to a solid over time. It is the second-most-used substance (after water), the most–widely used building material, and the most-manufactured material in the world. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that can be poured and molded into shape. The cement reacts with the water through a process called hydration, which hardens it after several hours to form a solid matrix that binds the materials together into a durable stone-like material with various uses. This time allows concrete to not only be cast in forms, but also to have a variety of tooled processes performed. The hydration process is exothermic, which means that ambient temperature plays a significant role in how long it takes concrete to set. Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galileo Galilei
Galileo di Vincenzo Bonaiuti de' Galilei (15 February 1564 – 8 January 1642), commonly referred to as Galileo Galilei ( , , ) or mononymously as Galileo, was an Italian astronomer, physicist and engineer, sometimes described as a polymath. He was born in the city of Pisa, then part of the Duchy of Florence. Galileo has been called the father of observational astronomy, modern-era classical physics, the scientific method, and modern science. Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of the pendulum and "hydrostatic balances". He was one of the earliest Renaissance developers of the thermoscope and the inventor of various sector (instrument), military compasses. With an improved telescope he built, he observed the stars of the Milky Way, the phases of Venus, the Galilean moons, four largest satellites of Jupiter, Saturn's r ...

Inclined Tower
An inclined tower is a tower that was intentionally built at an Inclined plane, incline. Towers are built with an incline in order to support the weight of another structure, such as the Montreal Tower. Some towers are built with an incline due to the steep terrain upon which they stand, or simply for aesthetics. Design Despite the outward appearance of an inclined tower as "leaning-over", they are as structurally sound as any non-inclined tower. The mass of the tower's upper section is always equal or less than the mass of the tower's lower section, ensuring the building remains balanced around its centre of mass. Inclined tower vs. inclined building Inclined towers are specifically distinguished from "Inclined building, inclined buildings" in that they are not built to be habitable, but to serve other functions. The principal function is the use of their height to enable various functions to be achieved, including: visibility of other features attached to the tower such as clock ...

The Leaning Tower Of Gingin, September 2021 05
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee'' ...

Indigenous Australians
Indigenous Australians are people with familial heritage from, or recognised membership of, the various ethnic groups living within the territory of contemporary Australia prior to History of Australia (1788–1850), British colonisation. They consist of two distinct groups, which include many ethnic groups: the Aboriginal Australians of the mainland and many islands, including Aboriginal Tasmanians, Tasmania, and the Torres Strait Islanders of the seas between Queensland and Papua New Guinea, located in Melanesia. 812,728 people Aboriginality, self-identified as being of Aboriginal and/or Torres Strait Islander origin in the 2021 Australian Census, representing 3.2% of the total population of Australia. Of these Indigenous Australians, 91.4% identified as Aboriginal, 4.2% identified as Torres Strait Islander, and 4.4% identified with both groups. The term Aboriginal and Torres Strait Islander peoples or the person's specific cultural group, is often preferred, though the term ...

Astrophotography
Astrophotography, also known as astronomical imaging, is the photography or imaging of astronomical objects, celestial events, or areas of the night sky. The first photograph of an astronomical object (the Moon) was taken in 1839, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography. Besides being able to record the details of extended objects such as the Moon, Sun, and planets, modern astrophotography has the ability to image objects outside of the visible spectrum of the human eye such as dim stars, nebulae, and galaxy, galaxies. This is accomplished through long-exposure photography, long time exposure as both film and digital cameras can accumulate and sum photons over long periods of time or using specialized optical filters which limit the photons to a certain wavelength. Photography using extended exposure-times revolutionized the field of professional astronomical research, recording hundreds of thousands of new ...
