The topic for my essay is going to talking about Chemistry and Technology, and has a focused on the invention and influence on the microscope. Chemistry has helped people look at technology in a different way, such as by the way we use it and how easy it is to find data faster. Technology has also changed Chemistry several ways. Some examples are finding new viruses and finding cures to prevent diseases from spreading around the world and.
The microscope has been a very important part of Chemistry since it was invented. There in some doubt, but Zacharias Jansenn seems to be the one who in vented the microscope in 1595 at Holland (source 1). He invented it by putting to magnifying glass together and a light under the sample he was looking at. Once he did this he could see 20 to 30 times on what he was looking at (source 1). He wanted to look at samples humans could not see with the naked eye. He looked at dirt, grass, and blood even he scraped the tartar of his teeth (source 2). What he saw will change the way everybody looks at everything today.
Society was in a crisis before the microscope was invented. Sickness was running rampant and people who were sick most of times eventually died from it. Many of the people were getting the common cold, flu, and sometimes the plague. People did not know what disease they had; they just knew the symptoms of the disease they had. People around the world were looking for an answer on how to stop what was going on with them. Nobody likes to be sick. Everybody tried many ways to find cures to heal the population of the sick but whatever they did only worked for a few days not if it worked at all. The remedies never fully cured the person from the disease. There was a big proble...

The microscope is an advancement in technology in Chemistry since it was invented since 1959. The technology that involves Chemistry has evolved as the Chemistry that involves technology. From looking at cells 500 times greater to the naked human eye, and from looking at cells to bacteria in an animal to what goes on in a plant and how it absorbs light, the microscope can change the world in just a second when a new discovery is made. People has come very close to discovering a cure from cancer but all the times it has failed time and time again A cure for someone who needs a cure for cancer can happen in a moment with the help of the microscope and the necessary resources. Once people look at life through a microscope, there is no stopping or telling on how many discoveries and cures we can find.
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.
So one major investment in the 1920's to science was Medicine. In 1921 two Canadian scientists made a medicine called Insulin. Insulin helped people suffering from diabetes which made the world a healthier place. Then in 1928 Alexander Fleming found a mold that could kill certain types of bacteria. This mold became...
This paper discusses the development and history of Microbiology and its impact on human health over time. This includes an examination of historical events that led to the development of techniques and procedures used for the handling of microorganisms, and
Lack of technology contributed to the fact that cholera couldn’t be studied in isolation during the 1854 outbreak. With the lack of technology there was also the lack of knowledge. The idea of germs living inside the water was an absurd idea because no one could see those
As the late 19th century progressed, technological ideas and inventions began to thrive. The notion that technology would impact life as we know it was an unbelievable idea to comprehend. People had no idea that something so simple such as the light bulb would become so vital to them and for century’s to come. Inventions such as, the typewriter, barbed wire, telephone, Kodak camera, and electric stove were created, however the major inventions created and use tremendously today are, Medicine, Electricity, and Transportation.
...mptoms and known pattern of disease. Experiments by scientists, Nicolle and Le Bailly in Paris, were the earliest explanations that influenza was caused by a filter-passing virus. They proved that influenza was due to a submicroscopic infectious agent and not a bacteria. Scientific experiments, such as these, had immediate preventative applications. They were part of an effort to create a vaccine that would prevent the influenza. Vaccines were considered the best preventative treatment at the time. Several scientists tried to create effective vaccines, each with a different understanding of the virus. Dr. Rosenow invented a vaccine to target the multiple bacterial agents involved from the serum of patients. He aimed to raise the immunity against the bacteria, and not the cause of the initial symptoms (Virginia).
By the nineteenth century, scientists had abandoned this theory (called spontaneous generation) as an explanation for the existence of visible animals, but not for diseases. Infections and illnesses were thought to have been caused by impurities in the air. Doctors did not understand the necessity of cleanliness when dealing with patients and were unaware that they could be transmitting diseases from one patient to another with their unwashed hands. Doctors in the mid-nineteenth century made revolutionary advances that influenced modern medicine. Three such men were Ignaz Semmelweis, Louis Pasteur, and Joseph Lister.
The 1800’s was a time of development in science. New and what seemed like crazy ideas were surfacing. These ideas were more easily accepted than in past years. There were new theories such as the Cell Theory by Mathias Schleiden and Theodor Schwann in 1838 (Farah 626) and the Atomic Theory by John Dalton (Farah 628).A little over a decade after the Cell Theory was proposed, Louis Pasteur discovered bacteria in 1850 (Farah 627).
Antonie van Leeuwenhoek was a scientist and was best known for his contributions to microbiology; he received the title of "the Father of Microbiology” and dedicated many years of his life to improve the microscope in order to attain incredible heights of precision of the microscopic lenses. He produced magnifications from up to 275X, with a resolving power of up to 1.4 µm. Moreover, he presented his findings from the material of animals and vegetables in extraordinary detail as well as being the first to observe a glimpse of bacteria that he found in water; the first illustration of the bacteria is demonstrated in a representation by Leeuwenhoek in the 1683 “Philosophical Transactions” publication. In this publication, Leeuwenhoek wrote to the Royal Society about his observations of the inside of an old man’s mouth. He found "an unbelievably great company of living animalcules [Latin for ‘little animals’], a-swimming more nimbly than any I had ever seen up to this time. The biggest sort... bent their body into curves in going forwards. . . Moreover, the other animalcules were in such enormous numbers, that all the water... seemed to be alive." These were among the first observations on living bacteria ever recorded.
Medicine is one area that constantly looks to use prior knowledge to discover new things. Take the HeLa cells for instance. The initial discover of these cells occurred in 1951. These cells came from a black woman named Henrietta Lacks. She was diagnosed with cervical cancer. He doctor took a segment of her tumor and sent it to Dr. George Otto Grey, who was the first scientist to successfully grow human cells in a culture. These cells would go on to be used in research for cloning, the polio vaccine, gene mapping and in virto fertilization. These cells were important to science because no scientist had an endless supply of cells ...
After the industrial revolution in the 18th century in Europe and America, there was the rapid industrial and economic growth in the 19th century, which in turn caused various scientific discoveries and various invention therefore making more progress in identifying illnesses and developing modes of treatment and cure, this was where modern medicine started. After the industrial revolution there were more industries, which in turn created a lot of work-related diseases and poor hygiene, also as the cities began to grow larger, more communicable diseases began to increase, cases like typhoid and cholera became epidemics. As well, due to the changes occurring, more and more people became more aware and since there was democracy there became an increase in demand for health care. There were also the wars that occurred, causing injuries which needed to be treated. Modern medicine evolves to solve the problems of the society at a given time and various advances in this mode of health care has occurred over the years. It has been seen that modern medicine is a positive influence in the society today for various reasons, the goal of the modern medicine is to achieve good health of the citizens, and modern medicine is experimental which is capable of advanced diagnosis. Likewise, modern medicine has an effect on the social and economic state of the modern society. Modern medicine is understood as the science of treating, diagnosing or even preventing illnesses using improved sophisticated technology. This mode of treatment involves a variety of methods, using diet, exercise, treatment by drugs or even surgery.
There are a lot of things not visible to the naked eye. What most of us don't realize is that there is a world full of wonders out there; A world full of diversity and "magic." A world called microscopy. It's amazing how one single device called the microscope can let us view things that are too small for the human eye. A microscope has the power to magnify object from 100x to as much as 1000x or higher. In fact, there are many microscopes, each with their own unique capability. Examples of these are the atomic force microscope, scanning probe microscope, and electron microscope. Microscopy is the technique in which a person is able to view images of structures that are too small for the naked eye. In light microscopy, light is reflected through a series of lenses that eventually illuminate the object being seen.
The SEM has many advantages over the older microscopes. One advantage is its large depth of field, which allows more of the chosen sample to be in the focus at the same time. Another advantage is that it has much higher resolution. Therefore, samples that are spaced closely together can be magnified at much higher levels. This microscope also gives the examiner much more control in the degree of magnification because the SEM uses electromagnets rather than lenses (Scanning Electron Microscope, n.d.). Another unique ad...
Microscopes have helped us to explore the vast detail in which our world works. Without the invention of microscopes we not be able to study a lot of things, for example; we could not study about cells, bacteria, plants, foods or microscopic insects this would cause the study of science and medicine to be set back hundreds of years. The invention of the microscope has been very helpful to doctors and scientists as scientists can study more in depth about atoms and doctors can help solve diseases with the help of the microscope as they can place the specimen (cells or tissue) on the stage of the microscope and examine
Technology has had a great impact on society when it comes to medicine. Medical technology has been around since the cave man began using rocks as tools to perform trephening. Since then there has been many new advancements in medicine due to technology. From painless needles to robots used for surgeries technology is around to stay.
