Hypothesis

Image
 Hypothesis is a suggested solution for an unexplained occurrence that does not fit into current accepted scientific theory. The basic idea of a hypothesis is that there is no pre-determined outcome.   a proposition made as a basis for reasoning, without any assumption of its truth. "the hypothesis that every event has a cause"   Alternative Hypothesis. The alternative hypothesis states that there is a relationship between the two variables being studied (one variable has an effect on the other). Null Hypothesis. Nondirectional Hypothesis. Directional Hypothesis.   hypothesis an educated guess about a possible solution to a mystery; a prediction or statement that can be tested       Power of Prediction. One of the valuable attribute of a good hypothesis is to predict for future.     Closest to observable things. A hypothesis must have close contact with observable things.     Simplicity.     Clarity.     Testabil...

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. ...

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 e...
