Chemistry is a science and an art. But it is not art for art's sake. Increasingly, chemistry is being used as a fundamental knowledge base to further innovations in bordering disciplines such as biology or medicine. At the School of Life Sciences in Muttenz, chemistry has this dual role....
This inherent curiosity led me to become a scientist. I studied Chemistry but soon enough I realized that being a chemist makes a huge mess or at least I made one in the lab! Fortunately, I then realized that computers exist and they make things much cleaner. I discovered that today it ...
Some chemistry examples in everyday life include the burning of gasoline (a chemical reaction), sunscreen (chemical that reflect harmful ultraviolet light), and even breathing (the extraction of oxygen gas from the air). What is chemistry in simple words? Chemistry is the study of the substances...
