Scientific instrument in the context of "Pendulum"

Observation in the natural sciences refers to the active acquisition of information from a primary source. It involves the act of noticing or perceiving phenomena and gathering data based on direct engagement with the subject of study.

In living organisms, observation typically occurs through the senses. In science, it often extends beyond unaided perception, involving the use of scientific instruments to detect, measure, and record data. This enables the observation of phenomena not accessible to human senses alone.

The history of technology is the history of the invention of tools and techniques by humans. Technology includes methods ranging from simple stone tools to the complex genetic engineering and information technology that has emerged since the 1980s. The term technology comes from the Greek word techne, meaning art and craft, and the word logos, meaning word and speech. It was first used to describe applied arts, but it is now used to describe advancements and changes that affect the environment around us.

New knowledge has enabled people to create new tools, and conversely, many scientific endeavors are made possible by new technologies, for example scientific instruments which allow us to study nature in more detail than our natural senses.

Dowsing is a type of divination employed in attempts to locate ground water, buried metals or ores, gemstones, oil, claimed radiations (radiesthesia), gravesites, malign "earth vibrations" and many other objects and materials without the use of a scientific apparatus. It is also known as divining (especially in water divining), doodlebugging (particularly in the United States, in searching for petroleum or treasure) or water finding, or water witching (in the United States).

A Y-shaped twig or rod, or two L-shaped ones, called dowsing rods or divining rods are normally used, and the motion of these are said to reveal the location of the target material. The motion of such dowsing devices is generally attributed to random movement, or to the ideomotor phenomenon, a psychological response where a subject makes motions unconsciously.

Carl Zeiss (German: [kaʁl ˈtsaɪs]; 11 September 1816 – 3 December 1888) was a German scientific instrument maker, optician and businessman. In 1846 he founded his workshop, which is still in business as Zeiss. Zeiss gathered a group of gifted practical and theoretical opticians and glass makers to reshape most aspects of optical instrument production. His collaboration with Ernst Abbe revolutionized optical theory and practical design of microscopes. Their quest to extend these advances brought Otto Schott into the enterprises to revolutionize optical glass manufacture. The firm of Carl Zeiss grew to one of the largest and most respected optical firms in the world.

The Whipple Museum of the History of Science is a museum attached to the University of Cambridge, England, which houses an extensive collection of scientific instruments, apparatus, models, pictures, prints, photographs, books and other material related to the history of science. It is located in the former Perse School on Free School Lane, Cambridge. The museum was founded in 1944, when Robert Whipple presented his collection of scientific instruments to the University of Cambridge. The museum's collection was 'designated' by the Museums, Libraries and Archives Council (MLA) as being of "national and international importance".

The museum is one of eight museums in the University of Cambridge Museums consortium.

The Musée des Arts et Métiers (French pronunciation: [myze dez‿aʁ e metje]; English: Museum of Arts and Crafts) is an industrial design museum in Paris that houses the collection of the Conservatoire national des arts et métiers, which was founded in 1794 as a repository for the preservation of scientific instruments and inventions.
