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. ...

Hypothesis

 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...

Microscope

 Microscope is a laboratory instrument used to examine objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using a microscopic. Microscopic means being invisible to the eye unless aided by a microscope.   There are several different types of microscopes used in light microscopy, and the four most popular types are Compound, Stereo, Digital and the Pocket or handheld microscopes.   5 Different Types of Microscopes:       Stereo Microscope.     Compound Microscope.     Inverted Microscope.     Metallurgical Microscope.     Polarizing Microscope.   A general biological microscope mainly consists of an objective lens, ocular lens, lens tube, stage, and reflector. An object placed on the stage is magnified through the objective lens. When the target is focused, a magnified image can be observed through the ocular lens.   At 100x magnifica...
