    Definition of microscope; the microscope is an instrument which is used for magnifying objects that are too small to see with the naked eye; such as cells, bacterias and other microorganisms (particles). It gives an enlarged image of the object. Definition of lens; a piece of glass, or another transparent material, with curved sides. Used for bending light rays (concentrating or dispersing) which passes through. The phenomenon that causes the light to bend when crossing the lens is called refraction

    developments of the microscope, it consisted of a powerful convex lens and an adjustable holder for the object being studied. This instrument would have been able to magnify objects up to 400x and with it he discovered protozoa, spermatozoa, and bacteria, and was able to classify red blood cells by shape. The limitation with this microscope was the single convex lens. This was fixed by the addition of a second lens, giving rise to the compound microscope which is the basis of light microscopes today.

    1. INTRODUCTION TO MICROSCOPY A microscope is an instrument used to see objects that are very small for the naked eye. The science of examining small objects using such a tool is called microscopy. Microscopic means invisible to the eye except aided by a microscope. 2. HISTORY FIRST Zacharias Jansen (1580–1638) invented a compound light microscope and after that Antony van Leeuwenhoek in 1632–1723 invented a simple (one-lens) microscope that earned a lot of importance worldwide.

    the use of a Scanning Electron Microscope (SEM) to examine and analyze metal samples that were subject to different failure tests. These failure tests included tensile tests, impact tests, and fatigue tests. SEM’s are useful because they provide a 3D view of the surface of the material, which improves the ability to examine the failure type at a microscopic level. In addition to this, the resolving power of a SEM is much stronger than that of a standard microscope, which enables the user to obtain

    In the article “Darwin Under the Microscope: Witnessing Evolution in Microbes” the author Carl Zimmer describes the transformation of the study of experimental evolution from the times of Darwin to the experiments that are still ongoing today, as well as how microbes have allowed researchers to observe natural selection and evolution within the lab. When Charles Darwin wrote his famous book The Origin of Species, he believed that natural selection would take too long to be studied within a lifetime

    Every organism in the universe requires water for its survival. Arguing out that water is good or bad is inconclusive. Water for human consumption is supposed to be subjected to quality tests so as to determine its safety for consumption and usage. A number of water sources around the globe suffer from some form of impurities. This makes it unsafe and unhealthy for individuals to use it. Challenges such as unsafe water, insufficient or the lack of quality healthy water has been an issue which has
