andy chuksSociology as a Science: Difference between Sociology and other Sciences Sociology is a science which attempts the interpretive understanding of social action in order thereby to arrive at a causal explanation of its course and effects. In "action" is included all human behaviour when and insofar as the acting individual attaches a subjective meaning to it. Action in this sense may be either overt or purely inward...

andy chuks 2. What is science?
To answer the question if sociology is a science or not, first we need to know what is science, otherwise the question does not make much sense. Actually current ph ilosophical views on the nature of science is diverse, and largely liberalized from previous views. First, they no longer accept strong criteria of falsification as...

andy chuks Biogas is a gas which is produced as a byproduct of certain types of anaerobic fermentation or gasification.
Biogas is generated from the anaerobic digestion of organic matter.
Biogas typically refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. Biogas originates from biogenic material and is a type of biofuel.... Read All 0009 March 2011
williams sodicMeteors, Meteoroid and Meteorite Explained A meteoroid is a sand- to boulder-sized particle of debris in the Solar System. The visible path of a meteoroid that enters Earth's (or another body's) atmosphere is called a meteor, or colloquially a shooting star or falling star. If a meteoroid reaches the ground and survives impact, then it is called a meteorite. Many meteors appearing seconds or... Read All03 December 2010Comment
JP WilliamsWhat is Antimatter? Antimatter particles are sub-atomic particles with properties opposite those of normal matter particles. For example, a positron is the antiparticle equivalent of the electron and has a positive charge. When a particle and its antiparticle meet, they annihilate, releasing massive amounts of energy, according to Einstein's famous equation E=mc^2, where... Read All25 October 2010Comment
JP WilliamsWeigh Less at the Equator? Amazingly, you would experience less gravity at Earthâ€™s equator. An object's gravitational pull on another object depends upon both objects' masses and their mutual distance.
Earth has a bulge at the equator created by the planetâ€™s rotation and a moving body's tendency to continue in a straight line. (Sometimes this is misleadingly... Read All25 October 2010Comment
JP WilliamsAcid Rain - How it occurs and Effects Acid rain occurs mostly in the Northern Hemisphere -- the more industrialized, dirtier half of the globe. Winds can sweep up emissions from high smokestacks and carry pollutants far from their original sources, crossing state lines and national borders in the process. Acid rain may not have the complete global range of greenhouse gases, but it is a... Read All06 October 2010Comment
andy chuksErosion - Meaning, Types and Effects I INTRODUCTION
Erosion, removal of rock and soil material by natural processes, principally running water, glaciers, waves, and wind. Erosion transports rocky material after the process of weathering has broken bedrock down into smaller, moveable pieces.
Through erosion the surface of the earth is constantly being sculptured into new forms. The... Read All05 October 2010Comment
andy chuksHow Cells Use Food and Air The Earth is surrounded by air. Air is a group of many gases (oxygen, carbondioxide, nitrogen etc). We breathe in oxygen and breathe out carbondioxide.
When we breathe in oxygen, the oxygen is carried by the blood to every cell in our body (The blood also carries food in liquid form). In every cell the oxygen combines with a substance in the food called... Read All05 October 2010Comment
andy chuksThe Ocean Bottom The Ocean bottom is divided into three main parts. The first part is called the continental shelf. The continental shelf starts where the part of the land we live on ends. It is part of the continent, but it is covered with water. The continental shelf is the shallowest part of the ocean. Its average depth is about 60 meters (200 feet).
At the end... Read All18 September 2010Comment
