Microscope Research Paper
The evolution of the microscope. The first form of the microscope was a crystal that was found by someone from a long time ago. The crystal was thick in the middle, but thinner around the egdes. The crystal made things look bigger when someone looked through it. The pearson also noticed that if the sun shone through the crystal, certain things could get burnt or set on fire. They were known as "magnifiers". Magnifiers were mentioned in the writings of the two Roman philosophers, Seneca and Pliny. Apperantly, maginfiers weren't really used much until the invention of the spectacles.
The oldest actual microscope was actually just a tube with a plate at one end and a glass lens at the other end. They magnified small objets by ten diameters. These amazed people when being used for magnifing small creepy organisms, bugs, mostly fleas. Thus, giving them the name, "flea glasses".
In 1590, Zaccharias Janssen and his son Hans,were experimenting with several lenses, when they noticed that objects near the lenses appeared to be larger. This led to the creation of the compound microscope and the telescope.
In 1609, Gaileo, known as the father of modern physics and astronomy, had heard of Janssen's experiments, and decided to experiment with the lenses as well. Eventually, Gaileo made a better instrument that had a focusing device on it.
Anton van Leeuwenhoek is known as the father of microscopy. He made lenses have up to a magnification of up to 270 diameters. He did this by shining the lenses. This led to the invention of his microscopes. His microscopes allowed him to be the first pearson to ever see bacteria, yeast plants, the circulation of blood corpuscles in capillaries, and the teeming life in a dr...

Future of the Microscope. The future looks good for microscopes. There are newer ones being made each year. Each one having better quality and smooth functionality than past microscopes. Scientists are also trying to improve the microscopes magnification ability.

One definition of a microscope is "an optical instrument that uses a lens or a combination of lenses to produce magnified images of objects." Holden Caufield can be symbolized by a microscope and its parts: the field of view, the focus, and the magnifier.
It was invented in 1658 by the one and only Christiaan Huygens(source 3). While he was an astronomer he looked at Saturn with his telescope hoping to study

1) A stationary body will stay stationary unless an external force is applied to it; 2) Force is equal to mass times acceleration, and a change in motion is proportional to the force applied; and 3) For every action, there is an equal and opposite reaction. (Bio.org, 2017) He invented the optics which he helped to inspire the build of the
The microscope became one of the definitive laboratory equipments for the different sciences. According to a biologist William Carpenter, the microscope was an instrument used for scientific research and to satisfy the curiosity of science and others. Mary Ward acknowledged others to the microscopic world of panoramic, comparing and promoting the scenes of the microscopic world. For instance, some authors were capable to spectacle the animal kingdom under it; for example, sea-urchins, barnacles, and even smaller being like infusorians. Likewise claimed by Lane Clarke, microscope is a gadget to discover and learn. On the other hand, microscope is not only to educate but to entertain people. The littlest details were able to be seen underneath it. It created an amusement shift in how people view the world and others. It could be an enjoyable method through stereoscopes, kaleidoscope, and
The word microscope is often used to define an instrument used for viewing small objects, such as bacteria, minerals, and cells that can’t be seen with the naked eye by magnifying them using a series of lenses. Microscopes vary from models and styles, but each consists of similar parts including lens, eyepiece, stage, adjustment knobs, light, nosepiece, and arm. The eyepiece allows an individual to look through it to view samples. Usually the magnification of an eyepiece 10x. The arm supports the tube which connects the eyepiece to the objective lenses and the base. The objectives are referred to as the different magnification lenses that are rotated on the nosepiece. Usually one will find three objective lenses on a microscope. They consist

Lockyer’s adult life consisted of arduous experiments and fascinating discoveries, that would benefit the world in the years to come . It was in 1865 when he borrowed a few objective lenses from T...
There were many scientist who helped with the early design of the telescope but Isaac Newton is known for inventing the reflecting or reflector telescope in 1668. This telescope was different because Newton used mirrors rather than lens. He used one mirror to capture the image whil the other mirror was used to reflect the image from the first mirror. This invention gave a clearer picture and helped to advance the study of planets, stars and other objects in the solar system.
Antoni and Hook were known for the development of the microscope. Before Antoni improved the microscope, the microscope could only magnify objects 20 or 30 times their natural size. Antoni, a Dutch lens-maker, learned to grind a lens that magnified over 200 times. One of Antoni’s inspirations came from a publication by Robert Hooke’s book Micrographia. In this book the term cell was used to describe the basic unit of a structure in plants and animal life. Hooker wrote about his observations through various lenses. Newton was the most important figure in the scientific revolution because of his book the Principia. In this publication Newton describes the universe and its guidelines. In this he created the universal law of gravity and its mathematical equation. He demonstrates that every object exerts an attraction to a greater or lesser degree on all objects. The Principia led to the creation of the Royal Society in
One of the most influential scientist associated with the telescope has to be Galileo. He took the design and reinvented the telescope into one of the first refractive telescopes we use to this day.
Galileo Galilei was an Italian astronomer who contributed greatly to the knowledge we have about science. He was known as the “father of modern science” and he studied the stars with a device that he perfected, called the telescope. The telescope is still used till today,

The invention of the bifocals was one of the most important inventions of the 1700s. They have changed the lives of both children and adults that have issues with their eyesight. They rid people of eyestrain and headaches. Also, bifocals rid people of the inconvenience caused by having to shift from one pair of glasses to the other. Bifocals also allowed for more types of glasses to be developed.
The earliest known telescope was created by Hans Lippershey in 1608. Others have claimed to have made the discovery of telescope but according to documents, he is the earliest who has applied for the patent. The telescope had an convex objective lens and a concave eyepiece.
