Because the physical universe is so vast, there are many different branches of science (Figure 1.1). is the process by which we learn about the natural universe by observing, testing, and then generating models that explain our observations. Science is the process by which we learn about the natural universe by observing, testing, and then generating models that explain our observations. This includes advances in medicine, communication, transportation, building infrastructure, food science and agriculture, and nearly every other technical field that you can imagine.Ĭhemistry is one branch of science. From the color that makes a rose so red to the gasoline that fills our cars and the silicon chips that power our computers and cell phones…Chemistry is everywhere! Understanding how chemical molecules form and interact to create complex structures enables us to harness the power of chemistry and use it, just like a toolbox, to create many of the modern advances that we see today.
