Chemistry As A Discipline

NUS Chemistry: The Central Science

Human mind has always been very curious to make investigations and know about various activities/phenomena occurring around him. This curiosity has led him to collect information through experiments and observations. The curious mind has also been responsible for the research activities of various people all over the world. The knowledge and data base acquired like this is then systematized in a way that the mankind takes maximum benefit out of it. This knowledge base is known as science. Science may, thus, be broadly defined as systematized knowledge gained by mankind through observations and experimentation. Science has been further classified into different branches due to its enormous expansion and diversified fields. Some examples are: Chemistry, Physics, Biology, Geology, etc. Chemistry is one of the most important discipline of science to which this present book is devoted.

Chemistry As A Subject And As A Central Science

Chemistry may be defined as the branch of science which deals with the study of matter, its composition, its properties and the changes which it undergoes in composition as well as in energy during various processes.

The word chemistry has been derived from the word alchemy, which means study of met also Alchemy itself might have come from al chemical marked effect on our present day life. Chemistry has helped us to meet all our requirement for better living. The continuous

research in the field of chemistry has resulted in the production of useful materials such as, clothes, drugs, artificial foods, plastics, rubbers, fertilizers, insecticides, weed killers, life

supporting products, etc., which have revolutionised our life.

Our life would have been very dull and dreary without the knowledge of chemistry. In fact, we can say, chemistry is everywhere in the world around us it is, in what we eat in what we breathe in how we live and even in what we are.

How Does Chemistry Influence All Other Sciences

Chemistry is the central science because it combines physics, biology, and medicine with the earth and environmental sciences.

You need knowledge of chemistry in order to understand a number of different types of processes, including, for example, the processes of life, the physical sciences, and the biological sciences.

The main role of chemistry is to explain the behavior of matter and the nature of chemical compounds. However, you can use chemistry as a tool to analyze and explain other sciences, such as the physics of matter, the properties of living organisms, the effects of environmental pollution, and even the origin and evolution of life on Earth.

Geology Geomorphology And Archeology

Why is chemistry called âthe central scienceâ??

Another field that is based on chemistry is geology. Rocks are made up of atoms, and the chemical composition of stone and soil determines hardness, erosion, and other physical qualities that shape the landscape. In geology, as well as archeology and many other fields, the gradual chemical changes that occur in radioactive elements enable carbon dating techniques that have revolutionized our understanding of the past.

What Do Chemists Do

The behavior of atoms, molecules, and ions determines the sort of world we live in, our shapes and sizes, and even how we feel on a given day. Chemists who understand these phenomena are very well equipped to tackle problems faced by our modern society. On any given day, a chemist may be studying the mechanism of the recombination of DNA molecules, measuring the amount of insecticide in drinking water, comparing the protein content of meats, developing a new antibiotic, or analyzing a moon rock. To design a synthetic fiber, a life-saving drug, or a space capsule requires a knowledge of chemistry. To understand why an autumn leaf turns red, or why a diamond is hard, or why soap gets us clean, requires, first, a basic understanding of chemistry.

A bachelor’s degree in chemistry is also an ideal pre-medicine degree. Medical schools do not require a particular college major, but a chemistry background will be helpful in the advanced study of biochemistry, endocrinology, physiology, microbiology, and pharmacology. Chemistry is also an excellent major for students planning careers in other health professions such as pharmacy, dentistry, optometry and veterinary medicine. All of these professional programs require chemistry for admission. Most require at least one year of general chemistry and one year of organic chemistry, both with laboratories. Many students have found that having a chemical background gives them a distinct advantage in these professional programs.

Why Is Chemistry Called Central Science

Chemistry is often called the central science because of its role in connecting the physical sciences, which include chemistry, with the life sciences and applied sciences such as medicine and engineering. Chemistry is used in Biology, material science, pharmacology, medicine and health, marine science, astronomy, etc.

If you are a Physicist, Biologist, Medic, or Engineer, chances are, you are working with things . Chemistry is the study of the how matter interacts with other matter. Thus doctors use chemistry to predict how a drug will interact with the body, a physicist will use it to understand the properties of the universe, etc. Basically, chemistry is a central science because everyone needs to know how matter behaves in order to do further study in any area.

Chemistry With Medicine And Biology

1.1 Lecture Video The Study of Chemistry

Medicine and biochemistry were advances in chemistry. Due to advancement in these two areas, the quality of life has been improving over time, and we lived far along within our ancestor state a few hundred years ago.

It is not due to luck or better genetic materials we have, but because chemical advances in disease kill and better drugs have been created.

Discoveries of new drugs happen every year in various places on the planet, and they enable us to live longer or even help us through the deadly diseases.

a few decades ago we didnt know anything about HIV and AIDS and then it came with scary science that we couldnt cure it and whoever had it would die at a young age. Chemistry and heavy research in the fields enabled the production of new drugs, which help fight the disease and perhaps not completely remove it from the body but hinder its development.

There is the expectancy of HIV patient was once very short, with deaths coming at the 30s and 40s now. However, life can nearly double to 60s and 70s, and it is because of those are too viral drugs.

Cancer was also at the forefront of research and drug companies, and there have been breaks with using CISPLATIN complexes, which can cure many types of cancer.

There are more drugs on the market now and more developed.

Chemistry is also essential for environmental science, energy industry, forensic and analytical departments.

Physical And Chemical Properties And Changes

The properties that chemists use to describe matter fall into two general categories. Physical properties are characteristics that describe matter. They include characteristics such as size, shape, color, and mass. These characteristics can be observed or measured without changing the identity of the matter in question. Chemical properties are characteristics that describe how matter changes its chemical structure or composition. An example of a chemical property is flammabilitya materials ability to burnbecause burning changes the chemical composition of a material. The observation of chemical properties involves a chemical change of the matter in question, resulting in matter with a different identity and different physical and chemical properties. Part of understanding matter is being able to describe it. One way chemists describe matter is to assign different kinds of properties to different categories.

We know from our experience with water that substances can change from one phase to another if the conditions are right. Typically, varying the temperature of a substance can cause a physical process in which a substance changes from one phase to another. Examples are summarized in Table \.

Chemistry: The Central Science

What are some changes in matter that are essential to daily life? Digesting and assimilating food, synthesizing polymers that are used to make clothing, containers, cookware, and credit cards, and refining crude oil into gasoline and other products are just a few examples. As you proceed through this course, you will discover many different examples of changes in the composition and structure of matter, how to classify these changes and how they occurred, their causes, the changes in energy that accompany them, and the principles and laws involved. As you learn about these things, you will be learning chemistry, the study of the composition, properties, and interactions of matter. The practice of chemistry is not limited to chemistry books or laboratories: It happens whenever someone is involved in changes in matter or in conditions that may lead to such changes.

Chemistry Is The Key To All Knowledge

There is nothing wrong with being curious about science. Chemistry is the key to all the knowledge we have today. Scientists have discovered many different things using chemistry. They are also the ones who invented the first nuclear weapons.

Chemists are also responsible for the development of modern medicine. Chemists have also improved the quality of air and water. Some of them have made breakthroughs in the development of new materials. In short, chemistry is really important for us to know. But, sometimes, we need to find out more about chemistry because we cant understand it very well.

What Is The Meaning Of Central Science

Chemistry is often called the central science because of its role in connecting the physical sciences, which include chemistry, with the life sciences and applied sciences such as medicine and engineering. The nature of this relationship is one of the main topics in the philosophy of chemistry and in scientometrics.

Schools Wikipedia Selection Related Subjects: General Chemistry

Chemistry is the science of matter at the atomic to molecular scale, dealing primarily with collections of atoms, such as molecules, crystals, and metals. Chemistry deals with the composition and statistical properties of such structures, as well as their transformations and interactions to become materials encountered in everyday life. Chemistry also deals with understanding the properties and interactions of individual atoms with the purpose of applying that knowledge at the macroscopic level. According to modern chemistry, the physical properties of materials are generally determined by their structure at the atomic scale, which is itself defined by interatomic forces.

So Why Is Chemistry The Central Science

1.1 The Study of Chemistry

As you see above, chemistry plays a rather central role in other sciences. This central role is best described using a hierarchical classification of sciences first developed by .

Sciences can be listed in order depending on the general framework for the area it precedes . Chemistry provides a significant amount of emergent ideas and concepts used in “higher fields of science”. Without an understanding of these concepts in chemistry, one could not fully understand the sciences that come after it on the hierarchy!

    The mass of a certain chlorine atom is 35 amu.

    A bottle with a label that reads Al contains aluminum metal.

    Al is the symbol for an aluminum atom.

  • The Domains Of Chemistry

    Chemists study and describe the behavior of matter and energy in three different domains: macroscopic, microscopic, and symbolic. These domains provide different ways of considering and describing chemical behavior.

    Macro is a Greek word that means large. The macroscopic domain is familiar to us: It is the realm of everyday things that are large enough to be sensed directly by human sight or touch. In daily life, this includes the food you eat and the breeze you feel on your face. The macroscopic domain includes everyday and laboratory chemistry, where we observe and measure physical and chemical properties, or changes such as density, solubility, and flammability.

    The microscopic domain of chemistry is almost always visited in the imagination. Micro also comes from Greek and means small. Some aspects of the microscopic domains are visible through a microscope, such as a magnified image of graphite or bacteria. Viruses, for instance, are too small to be seen with the naked eye, but when were suffering from a cold, were reminded of how real they are.

    The Centrality Of Chemistry

    Iwas a biology major for the first twoyears of college. As required, I took a course in organic chemistryand was subsequently captivated: I wanted more. I asked the coursesprofessor, Should I change my major to chemistry even thoughI am still interested in biology? He said, Carolyn,you should change your major to chemistry because you are interested in biology. It was a message of chemistryscentrality to so many areas of science in which molecules and materialsare the fundamental units of function. And now, I am proud to celebratechemistrys central role in science and society with the launchof this exciting new journal, ACS Central Science.

    Popularized almost 40 years ago, the term centralscience is now widely used to describe chemistrysfocal role in bridging the physical and life sciences, and the basicsciences with applied disciplines like medicine and engineering. Indeed,chemistry is at the crux of so many of the 20th and now 21st centuriestransformative discoveries and technologiesfrom materials,fuels and medicines to computing and genome sequencingthatone might expect the chemical sciences to be most highly revered bysociety at large. And yet, chemistry often takes a back seat to otherdisciplines in the publiceye perhaps reflecting the fields pervasive, foundational,and therefore often overlooked role in major scientific advances.When asked who makes medicines, for example, many people answer doctorsrather than chemists.

    Key Concepts And Summary

    FIGURE 4.4 A precipitation reaction.

    Chemistry deals with the composition, structure, and properties of matter, and the ways by which various forms of matter may be interconverted. Thus, it occupies a central place in the study and practice of science and technology. Chemists use the scientific method to perform experiments, pose hypotheses, and formulate laws and develop theories, so that they can better understand the behavior of the natural world. To do so, they operate in the macroscopic, microscopic, and symbolic domains. Chemists measure, analyze, purify, and synthesize a wide variety of substances that are important to our lives.
