Microscope

argument can also be made for the Glass Age. Throughout this course we have covered many topics while using a wide variety of equipment and technology all made possible through the advancements of glass. From window panes absorbing UV radiation, microscope lenses or eye glasses, to the fiberoptic cable that keeps us in an information age. Todays world would not be possible without glass. The first manmade glass was discovered in eastern Mesopotamia around 3500bc. Around 2000 years later glass vessels

the invention of the microscope and its subsequent improvement, cells became visible and many new discoveries were made about them. Even today the study of cells reveals more detail, and its secrets, which are in fact the secrets of life itself, are revealed with ever increasing clarity. In 1665, English Scientist and Microscopist Robert Hooke described a honeycomb-like network of cellulae (Latin for little storage rooms) in cork slice using his primitive compound microscope. Robert Hooke used the

light microscope and an immersion oil lens by observing prepared slides of various bacteria and blood slides. We are also learning to indentify and observe the various shapes and characteristics of bacteria, as well as, yogurt cultures (fresh and prepared) and blood samples under a microscopic view. We will also be able to distinguish between blood cultures and bacteria specimens. Procedure: Exercise 1: Viewing Prepared Slides The first step is to assemble the compound light microscope.

solutions of 0.9% of sodium chlorine, 10% of sodium chlorine and distilled water to individual slides containing a drop of blood, then placed under the microscope, the following observation listed below took place, and were compared to the original slide number one. Slide#1 with one drop of sheep’s blood. The first slide was placed under the microscope under the magnification of 40x, and a thick red layer appeared with a white streak on the side. There was little air bubble spread on the layer, which

real problems. Even though they have a different objective, they, however, work together to facilitate each other to grow. The knowledge posed from science led to the creation of technology like telescope while the telescope technology led to a microscope that allows researchers to discover nature in a new era. According to an article by Rice University, a telescope is one of the dominant instruments of what has been referred to as the Scientific Revolution. However, according to the article, they

Additionally, a scanning electron microscope was used occasionally by the state’s experts. (Supreme Court) Agent Deadman testified about the fibers taken from Williams’, the cars, and his dwelling. He took samples of fibers from a bedspread, a blanket, and carpeting in Williams’ bedroom

Telescopes are used to in astronomy. Telescopes, too, can work using convex lenses. Telescopes are an upgrade from microscopes. The camera is an everyday item. Used to store photos in it's memory, the camera also uses magnification to zoom in to take a picture. Every magnified image from convex lens has something in common. First of all, it magnifies an image. But the

1. ABSTRACT A region of embryonic rat brain was digitally photographed with an Olympus BX40 Microscope equipped with a 10MP (MU1000) video camera using four different objectives (4x, 10x, 20x, 40x). The different objectives were used to analyze the value of different resolutions in balancing the amount of work needed to make the pictures with the worth (or information value) of the image when using Photoshop (version 12.0). The images captured were montaged and arranged into series. This information

The resolution of optical microscopes is fundamentally limited by the diffraction of light, as postulated by German physicist Ernst Abbe in 1873. This means that a microscope cannot distinguish two objects located closer than λ/2NA, where λ is the wavelength of light and NA is the numerical aperture of the imaging lens (2). Although elucidation of cell functions and subcellular processes has benefited from advances in fluorescent microscopy, this diffraction limit has fundamentally hindered optical

this case, we use negative staining. In negative staining, we will place a single drop of nigrosin on a clean microscope slide. By applying aseptic technique, we will transfer a little bit of our phage from the plaque and mix it into the drop of nigrosin on the slide. Another microscope slide will be used to spread out the drop into a film. Air dry the film and observe the slide under microscope according to correct techniques. High purity of bacteriophage preparation can be obtained by using ion-exchange
