Chemistry is everything

Chemistry has accompanied humans throughout their existence in their exercising imagined usages of matter. Matter has been everything for Mankind and has been the chief medium for Mankind s creative manipulations. Matter is chemistry, and chemistry is the science of Man, who is made of matter

SCHEME 11.1 Cytosine and the form in which it is methylated on the carbon in position 5, a transformation which is accomplished by the enzyme DNA methyltransferase (NH is in position 1, and the numbers increase anticlockwise).

The world of chemistry involves every single aspect, comer, and micro drop of everything that is matter. Our solar system and the entire universe all function on a chemical level—In essence, chemistry is everything. The universe and everything in it is composed of atoms and molecules, and within this massive space, there exists tens of millions of chemical compounds—either known or unknown. The compounds that are known make up only 5% of the naturally occurring compounds, leaving a massive 95% of them being synthetic (prepared in the lab)—all explosives are synthetic. 

I now wish to cap it all in a relaxed manner and show that chemistry is everything and everything is chemistry. 

The course ends with a popular lecture (Lecture 11) entitled Chemistry is Everything..., which is followed by demonstrations that emphasize the magic and fun of chemistry. 

Chemistry is the science of matter and the changes it can undergo. The world of chemistry therefore embraces everything material around us—the stones we stand on, the food we eat, the flesh we are made of, and the silicon we build into computers. There is nothing material beyond the reach of chemistry, be it living or dead, vegetable or mineral, on Earth or in a distant star. 

Organic chemistry is very much the same. It is one long story, and the story actually makes sense if you pay attention. The plot constantly develops, and everything ties into the plot. If your attention wanders for too long, you could easily get lost. 

Group I relies, as said before, on the reductionistic ideal that everything, in the field of chemistry, is amenable to the first principles and that a correct applications of the principles, accompanied by the necessary computational effort, will give the answer one is searching. It is a rigourous approach, based on quantum mechanical principles, in which the elements of the computation have no cognitive status, unless when employed to get numerical values of physical observables or of other quantities having a well defined status in the theory. 

Chemistry is a dynamic science. Thank goodness, every people is inventive. The effects of everyday life are noticed in everything we see... 

Both in the preparation of intermetallics and in their handling, special problems are encountered due to impurities present in the materials involved or produced by unwanted side reactions, such as reactions with the atmosphere, the containers, etc. The purity control is especially important when working at high temperature. It is well-known that the fundamental law of high-temperature chemistry is that . .. everything reacts with everything ... 

If you had to write a math equation, you probably wouldn t write, Twenty-eight plus fourteen equals forty-two. It would take too long to write and it would be hard to read quickly.You would write, 28 + 14 = 42. Chemistry is the same way. Chemists have to write chemical equations all the time, and it would take too long to write and read if they had to spell everything out. So chemists use symbols, just like we do in math. 

Like most stories, that of chemistry has another side, less often noted or remarked but a whole lot more pleasant. The world of chemistry is the world of molecules. It is a complex, critical, and fascinating world. Molecules and their constituents (atoms) make up all matter. Specific molecules affect every aspect of our lives every day, frequently for better but occasionally for worse. The simple fact is that almost everything that we use in daily life has been chemically modified in some way consider plastics, alloys, detergents and soaps, paper, perfumes and colognes, and our drinking water. It is difficult to imagine life without the products of modem chemistry. 

In short, and as in everything, we need to keep a balance between the temptations of biology and the temptations of materials science. We should certainly show how physical chemistry is relevant to these topics, but not lose sight of the simplicity of the central core of ideas that we are trying to convey. We must educate people into flexibility. 

I elcome to the world of chemistry—a world where everything around you can be traced to these incredibly tiny particles called atoms. Chemistry is the study of how atoms combine to form materials. By learning chemistry, you gain a unique perspective on what things are made of and why they behave as they do. 

The fundamental idea of modern chemistry is that matter is made up of atoms of various sorts, which can be combined and rearranged to produce different, and often novel, materials. The person responsible for this master-concept of our age (Greenaway, p. 227) was John Dalton. He applied Newton s idea of small, indivisible atoms to the study of gases in the atmosphere and used it to advance a quantitative explanation of chemical composition. If French chemist Antoine Lavoisier started the chemical revolution, then it was Dalton who put it on a firm foundation. His contemporary, the Swedish chemist Jons J. Berzelius, said If one takes away from Dalton everything but the atomic idea, that will make his name immortal. ...
