What is the purpose of chemistry?
It illuminates and controls molecular systems through the design and development of tools to study atomic and molecular behavior. Through its focus on the energetics of chemical structure and transformation, it also provides the molecular foundation for all energy conversion technologies and the economic and societal benefits they provide. Leveraging a rich community of institutes, centers and training programs such as the Global Climate and Energy Project and Precourt Institute for Energy, Stanford scientists are developing new strategies to understand and manipulate atomic and molecular behavior, the interaction of light with matter, and the dynamics and energetics of bond rearrangements that are critical to new energy technologies.
How do lasers help us understand chemical reactions?
The use of lasers to study chemical reactions at the molecular level, pioneered at Stanford, led to seminal contributions to our understanding of molecular collision processes. New methods that predict and explain how atoms move in molecules are used both to design new molecules and to understand the behavior of those that already exist, including molecular responses to light and external force. High-quality [SW1] nanotubes from a Stanford-developed synthesis are widely used to investigate the electrical, mechanical, optical, electro-mechanical and thermal properties of quasi-one-dimensional systems.

The Study of Physics and Chemistry
Science is learning about the world by observing, listening, and recording. There are multiple branches of science, two of which are physics and chemistry. These two branches both deal with the study of matter, but they are different in how they study matter and what they focus on. Matter is anything that has mass and takes up space.
What is Physics?
Physics is the study of how matter interacts. Physicists observe, experiment, and collect data in order to find physical laws to explain how everything in the universe behaves and functions. Physics stems from ancient Greek philosophy and was commonly known as "natural philosophy" until the late 18th century.
What is Chemistry?
Chemistry studies how matter is made - its properties, chemical makeup, and how it reacts and changes. The beginnings of chemistry focused more on practical uses, such as creating new things to make lives better. Creating soaps, perfumes, etc. were the goals of chemists, not understanding what those substances were made of and their properties.
