Essay about The History of Chemistry - 833 Words

Chemistry is the science of the composition, structure, properties, and reactions of matter, especially of atomic and molecular systems (dictionary). And technology is the branch of knowledge that deals with the creation and use of technical means and their interrelation with life, society, and the environment, drawing upon such subjects as industrial arts, engineering, applied science, and pure science (dictionary). Chemistry helps our advances in technology, and technological alterations that affect our lives in many ways everyday. Because of science, we have complex devices like cars, X-ray machines, computers, and phones. But the technologies that science has motivated consist of more than just hi-tech machines. Technology extends our†¦show more content†¦This makes it a type of ionizing radiation and making it harmful to living tissue. They are fully controllable, unlike natural sources. But have been proven to be harmful to our health but enough research has been condu cted to ensure maximum protection to the patients. (Artificial Radiation).But also if you limit the amount of radiation exposure it will be safe for the patient to use. Medical X-rays have a disadvantage because they expose people to radiation. FDA regulates radiation-emitting products including X-ray machines. But everyone has a crucial role in reducing radiation while still getting the maximum benefit from X-ray exams. (Reducing Radiation from Medical X-rays) But when treating cancer patients they may be healed through radiotherapy, where beams of high energy X-rays or gamma rays from cobalt-60 are used. The ionizing capability of X-rays is aimed to kill the malignant cells, so they can reduce the dose around the healthy tissue. Artificial radiation is limited because of the risk factors it contributes. For example people have an increased chance of developing cancer later in life or developing cataracts and skin burns caused by exposure to very high levels of radiation. The X-ray machine has both its advantages and disadvantages. X-ray machines have had a major impact on our society. X-rays revolutionized how doctors detected disease and injury.

The beginning of chemistry was first acknowledged in 10,000 BC. The ancient civilizations used technologies that came to become the makeup of the many branches of chemistry. These early civilizations would extract metal from ores, make pottery and glazes, beer and wine fermentation, extraction of chemicals from plants for medicine, making fat into soap, making glass, and many chemistry related tasks were done. AlchemistsRead MoreThe History of Chemistry Essay798 Words   |  4 Pages Chemistry and technology are together and separate. Chemistry uses technology and technology uses chemistry. The history of chemistry and technology is long going back to the ancient times. Chemistry was used even by the oldest civilizations, like Egypt. It was really popular during the medieval times. Back then it was called Alchemy, which is turning metal into gold or even about the philosopher’s stone. As the years went by, Alchemy becam e a lost art and chemistry took it in place. Chemistry ledRead MoreEssay on The History of Chemistry844 Words   |  4 PagesChemistry is defined as, â€Å"the study of the composition, structure, and properties of matter, the processes that matter undergoes, and the energy changes that accompany these processes† (Davis 3). Chemistry has been around since the dawn of time, way before humans realized what chemistry was or its importance. The building blocks of the earth, such as minerals of the soil and atmospheric gases, all arise from chemical elements. Natural resources are all chemicals or chemical compounds, and the studyRead MoreThe History of Chemistry Essay844 Words   |  4 PagesChemistry has been around for a very long time. Chemistry is the branch of physical science that studies composition, properties, energy, and behavior of matter. It is said that chemistry has been around since prehistoric times. This was in the form of everyday objects like pottery, cosmet ics and perfumes, and extracting metals from ores. Chemistry is based on the discovery and study of elements. Some elements were known to ancient man, but most were discovered by chemists and alchemists. Some sayRead MoreThe History of Chemistry Essay1235 Words   |  5 PagesThe History of Chemistry Chemistry is the science of the composition and structure of materials and of the changes that materials undergo. It is also used in improving standards of living, making it possible for such substances as rubber, nylon, and plastics to be made from completely different materials. New materials and new properties of old materials are always being discovered. Some earlier products discovered from chemical reactions are ceramics, glass, and metals.

Chemistry was concerned anything that was pottery, dyes or crafts that were developed but not considerable skills because no one truly understood its purpose. The basic idea of elements or compounds were first formulated by Greek philosopher during 500 to 300 B.C when people believed fire , water, earth, and air combined to form all living and non-living things. In the beginni ng of Christianity an ancient Egyptian and GreekRead MoreEssay on The History of Chemistry928 Words   |  4 PagesChemistry has been around for a very long time. Chemistry dates back to as far as the prehistoric times. If you put the amount of time chemistry takes up in a timeline, you would split it into four general categories. The four categories are: prehistoric times - beginning of the Christian era (black magic), beginning of the Christian era - end of 17th century (alchemy), end of 17th century - mid 19th century (traditional chemistry), and mid 19th century - present (modern chemistry).

It has even been dated to times as early as the Prehistoric Era, and all the way up to now, the Present. We use Chemistry on a day to day basis. From Jewelry, to Fire-Works, Soap, and also, even the food we eat. Often people look at Chemistry and are bored because of the information they may not know. Science is everywhere, we just have to open our eyes and explore the world of Science.

By 1000 BC, ancient civilizations used technologies that would eventually form the basis of the various branches of the subject. Examples include extracting metals from ores, making pottery and glazes, fermenting beer and wi ne, extracting chemicals from plants for medicine and perfume, rendering fat into soap, making glass, and making alloys like bronze.

So what if chemistry sounds boring to some people, everyone has their own opinion about a subject that you don’t want to talk about in class or the subject you know so well that if someone asked you a question you could answer in a heartbeat. Well for me chemistry is the subject I don’t know very well at all and is hard for me to learn
