Over the course of the last 5000 years, mankind’s knowledge has been constantly advancing. Chemistry, a branch of science, has experienced a tremendous leap and expansions since ancient Greek civilization. One of the major breakthroughs in the advancement in Chemistry was the creation of the Atomic theory, which laid a foundation for the modern-day Chemistry and future of science. The Atomic theory introduced the idea of atoms, which are defined as the discrete units of matter. There are five key scientists that significantly contributed to the Atomic model over a span of thousands of years. They are: Democritus, John Dalton, J.J. Thompson, Ernest Rutherford, and Niels Bohr.
People also benefit from atomic research in the medical field. Many people are aware of the wide use of radiation and radioisotopes in medicine. Nuclear medicine mostly uses radioisotopes which emit gamma rays from within the body. Estimates show that about one out of every three hospital patients benefits in some way from the use of nuclear medicine. Just think, every time you have an X-ray taken you are benefiting from nuclear research. Without X-rays, doctors would have a far greater time trying to set a broken bone if they even knew it was broken! Another common medical procedure that involves atomic research is the Cat-Scan. During this procedure the patient is injected with a radioactive isotope which shows the flow of blood through the
Knowledge, the key to progress, has proven to be a human being’s most powerful and significant weapon. We gain knowledge when we put our brain to work at the problems we need to solve in life. It doesn’t matter what we are trying to accomplish, whether it be creating a new technology or learning how to put together a puzzle, the matter of fact is that both request great examination and research to resolve and learn. Scientific research is a technique used to investigate phenomena, correct previous understanding, and acquire new knowledge. Knowledge could lead us to a possible cure for cancer, an alternative for fossil fuels, and the creation of a revolutionary technology. Nevertheless, all these benefits are a reason why
Nuclear medicine technology has advantages and disadvantages just as any other career. Using nuclear medicine technology could diagnose a lot of harmful diseases. Also, it is more effective treatment for most categories of cancerous diseases and conditions in some medical institutions. This type of medicine technology helps physicians perform their responsibility of patients’ therapy easily; moreover, when a serious disease developed in the patient’s body, the x-rays of this medicine technology could scan the most sensitive part of the patient’s body.
My paper is about Irene Joliot – Curie the Nobel – Peace Prize winner that created the first artificial radioactive element. Her life was very successful and fulfilling. Irene’s life was very successful, because she accomplished many things and inspired future scientist. Her and her mom’s work was very useful in World War I. Her work with radiation also became very important to new discoveries of atoms.
“Science makes people reach selflessly for truth and objectivity; it teaches people to accept reality, with wonder and admiration, not to mention the deep awe and joy that the natural order of things brings to the true scientist” a famous quote by physicist, Lise Meitner. In Meitner’s years she made numerous discoveries and received multiple honors during and after her time. Meitner discovered nuclear fission with her partner Otto Hahn and was honored to receive multiple awards and honors.
When the words “nuclear chemistry” come to mind, many mixed emotions surface. On one side, a picture of devastated cities that were flattened by a bomb capable of freezing the shadows of people on the streets comes to mind. And the other picture: harnessing exponential amounts of energy, saving lives, and defeating cancer once and for all. No matter what stance is taken, the Atomic Age has both turned people against each other, but also has provided grounds for defeating a disease that hits each and every one of us at home, and that disease is cancer. When weighing the pros and cons of the Atomic Age, the pros clearly outweigh the cons. This era has brought upon clean, reusable energy, medical advancements beyond our dreams, and a better understanding of invisible radiation.
Being the second year student of the Faculty of Physics and Technology, I acquired the knowledge about Medical Physics for the first time. Heretofore, in my understanding, the use of radiation in medicine was limited with the fluorography which we had every year before final exams. Once a week, I and my classmates participated in a Physics Club under the direction of the head of the Department of Theoretical and Nuclear Physics where we considered the problems of Modern Physics. During one of these meetings, the professor told us the thought-provoking stories about successful oncology surgeries of brains and his plans to build a Nuclear Medicine research center in coming years in our country which caused my interest about Medical Physics and
These contributions now make up the basic grounds for what we know of atoms today. As science grows, we will see that we can go further in this and not only prove these same experiments but improve them. It was the work of these four J.J Thompson, Rutherford, Millikan and, Einstein that we have this information now and are to utilize it to the very last
The most important properties of atomic and molecular structure may be exemplified using a simplified picture of an atom that is called the Bohr Model. This model was proposed by Niels Bohr in 1915; it is not completely correct, but it has many features that are approximately correct and it is sufficient for much of our discussion. The correct theory of the atom is called quantum mechanics; the Bohr Model is an approximation to quantum mechanics that has the virtue of being much simpler.
"It is the function of science to discover the existence of a general reign of order in nature and to find the causes governing this order. And this refers in equal measure to the relations of man - social and political - and to the entire universe as a whole." This quote from Dmitri Mendeleev, a famous chemist from the mid-1800s, helps illustrate both his work as a chemist and his opinion about the importance of scientific research and education. Dmitri Mendeleev was an important chemist and influential scientist whose discovery of the periodic table helped contribute to society by creating a way for the elements to be categorized, allowing other scientists to easily study, identify,
With the given development and current state of nuclear medicine, develop an argument for how a nuclear medicine should be used in the future.Nuclear medicine ensure an accurate medical evaluation and helps detect and evaluate diseases. Ex: Brain disorders, Heart diseases and cancer. The Nuclear medicine is relatively safe. It can be used to determine whether or not organs are functioning normally. Nuclear medicine shows whether the blood supply to the is adequate or not. It also detects cancers at an early stage and determining the extent of cancer and asses the response of cancer to treatment. They also discover whether the heart can pump blood adequately and identifying abnormal brain lesions without exploratory surgery. It detecting whether
What is the atomic structure you may ask? Well, it’s the law stating the structure of an atom. It is composed of a positively charged nucleus containing a certain amount of protons (positive), neutrons (neutral charge), and electrons (negative). The amount of each subatomic particle (proton, neutron, and electron) all depend on what the element is. Now although this statement may seem fairly simple it was most definitely not. People have been studying the atomic structure for more than 300+ years and are still studying it. So after reading this you may wonder who even made this atomic structure up. After hundreds of years of research there is not any one individual who made the structure up but roughly
Humanity’s interest in unknown world has been universal and enduring. Accompany with human development, discovery the unknown world has become more and more important to human life. Some people think discovery is a good thing. They will tell you how X-ray used by medical professionals to help diagnose and treat a wide range of medical problems. They will also tell you what a mass your life will be if Benjamin Franklin did not discovered electricity. But other argue people think discovery bring disaster to human. They will tell you if Martin Heinrich Klaproth did not discover uranium, maybe atomic bomb would not been invented. Although the question about whether discovery always a good thing has so many
Science has many productive results which can be seen by digging out the history of mankind, though they are some negative aspects of this progress, but overall innovation and promotion of technology has modernized the every aspect of the human life.
