Telescope

Image
 Telescope is an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, or various devices used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation.   The first person to apply for a patent for a telescope was Dutch eyeglass maker Hans Lippershey (or Lipperhey). In 1608, Lippershey laid claim to a device that could magnify objects three times. His telescope had a concave eyepiece aligned with a convex objective lens.   Primary mirror (for reflecting telescopes), which carries the same role as the primary lens in a refracting telescopes. Eyepiece, which magnifies the image. Mounting, which supports the tube, enabling it to be rotated.   Types of Telescope. There are three main types of telescope. These are refracting telescopes, Newtonian telescopes and Schmidt-Cassegrain telescopes.   The Arecibo radio telescope still represents the largest single-aperture telescope ever constructed, with it

Seismology

Image
 Seismology is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies.   Seismologists also apply what they learn from studying the Earth's structure and other geological events, such as tsunamis, for commercial and other purposes, such as detecting nuclear explosions.   There are three basic types of seismic waves – P-waves, S-waves and surface waves. P-waves and S-waves are sometimes collectively called body waves.   John Milne father of Modern Seismology.   Charles F. Richter, American physicist and seismologist who developed the Richter scale for measuring earthquake magnitude. Born on an Ohio farm, Richter moved with his mother to Los Angeles in 1916.   DROP to the ground; take COVER by getting under a sturdy table or other piece of furniture; and HOLD ON until the shaking stops. ... Stay away from glass, windows, outside doors and walls, and anything that could fall, such as lighting fixtures or furniture

Scientist

 Scientist is a person who conducts scientific research to advance knowledge in an area of interest. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science.   Notable scientists Nikola Tesla (1856-1943 AD) Albert Einstein (1879-1955 AD) Sir Isaac Newton (1643-1727 AD) Louis Pasteur (1822-1895 AD) Marie Curie Sklodowska (1867-1934 AD) Thomas Alva Edison (1847-1931 AD)  Aristotle (382BC-322BC)   Few individuals have had as profound an impact on science as Galileo, whose groundbreaking inventions and discoveries earned him the title 'the father of science'. Galileo was an experimentalist who for the first time had the insight and talent to link theory with experiment.

Science

 Science Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3500 to 3000 BCE.   Physical science       Physics.     Chemistry.     Earth science.     Space Science or Astronomy.     Biochemistry.     Microbiology.     Botany.     Zoology.   Psychology is a science because it follows the empirical method. An empirical method involves the use of objective, quantitative observation in a systematically controlled, replicable situation, in order to test or refine a theory.  

Scale

 Scale an instrument or machine for weighing. 2a : a beam that is supported freely in the center and has two pans of equal weight suspended from its ends   oun Zoology.       one of the thin, flat, horny plates forming the covering of certain animals, as snakes, lizards, and pangolins.     one of the hard, bony or dentinal plates, either flat or denticulate, forming the covering of certain other animals, as fishes.   any thin, platelike piece, lamina, or flake that peels off from a surface, as from the skin.   a sequence of marks either at regular intervals or else representing equal steps, used as a reference in making measurements. a measuring instrument having such a scale. the ratio between the size of something real and that of a model or representation of it.

Retort

 Retort In a chemistry laboratory, a retort is a device used for distillation or dry distillation of substances. It consists of a spherical vessel with a long downward-pointing neck. The liquid to be distilled is placed in the vessel and heated.   Retorts sterilize food after it is sealed in a container by steam or other heating methods. Typically, the sterilization temperatures vary from 230°F/110°C to 275°F/135°C. ... Newer agitation retort processes have reduced cook times, resulting in energy savings and less degradation of the food quality.   The steam-air retort uses a mixture of steam and air, which is added to create an over-pressure in the retort. The air over-pressure allows thermal processing of a wide variety of containers including: glass, metal cans, rigid plastic, and flexible pouches.   It also means like to counter in other references.
