Why should we study Chemistry? Well I’ll tell you why I think I would study Chemistry‚ why it’s so important and crucial to know and understand. A couple reasons why are that I want to become a doctor in the future‚ I can see Chemistry in life‚ and I want to make a difference in the world. Can’t you agree that Chemistry is everywhere you look‚ I would definitely say so? Clearly‚ then we can see Chemistry in our daily lives. Just stop and look around you sometime. Look at a car for instance‚ you

I waited patiently by the bench in what all Harvey Mudd chemistry majors call the "Super Lab‚" staring for what seemed to be hours at a small flask bubbling with something that looked like a cross between Pepto-Bismol and whipped cream. I was waiting for the color to turn just the right shade of blue before I could go home for a late dinner‚ but it was obvious that this solution was as far from blue as baseball is from rugby. I realized then that "Super Lab" was not so Super‚ and neither was a career

Role of Chemistry in Every day Life Chemistry has played a key role in determining the nature of the modern world. In reality chemistry is much interesting for both study and practice. While defining chemistry let us consider a traditional definition which states ’Chemistry is the science of matter which undergoes changes during chemical reaction’. But in reality chemistry goes beyond its traditional definitions. From the evolution of mankind itself‚ chemistry had a close connection with the daily

importance of chemistry in biology. Chemistry is an important part of biology. Modern biology overlaps with chemistry in explaining the structure and function of all cellular processes at the molecular level. Chemical principles are important in modern cell biology because all living cells are made up of chemicals and many chemical processes occur in various living organisms. In biology you learn about living organisms and their composition. Organisms are alive because of chemistry. Chemistry is the
