Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Solomon is renowned for her insightful and persuasive use of atmospheric chemistry to comprehend two of the most important environmental problems facing humanity today: the thinning ozone layer and climate change. She is also well-known for her skillful presentation of environmental science to decision-makers, which helps to move legislation along.
The phrase "Better Living Through Chemistry" (BLTC) is a variant of a DuPont advertising slogan, "Better Things for Better Living...Through Chemistry". DuPont adopted it in 1935 and it was their slogan until 1982 when the "Through Chemistry" part was dropped. Since 1999, their slogan has been "The miracles of science". [1]
Environmental chemistry involves first understanding how the uncontaminated environment works, which chemicals in what concentrations are present naturally, and with what effects. Without this it would be impossible to accurately study the effects humans have on the environment through the release of chemicals .
A communications artifact (Rugby Aerial Tuning Inductor) at the Science Museum, London, UK . Science and technology studies (STS) or science, technology, and society is an interdisciplinary field that examines the creation, development, and consequences of science and technology in their historical, cultural, and social contexts.
Many social scientists and organizations in civil society suggest that technology assessment and governance should also involve public participation. The exploration of the stakeholder's perception is also an essential component in assessing the large amount of risk associated with nanotechnology and nano-related products.
The importance of stone tools, circa 2.5 million years ago, is considered fundamental in the human development in the hunting hypothesis. [citation needed]Primatologist, Richard Wrangham, theorizes that the control of fire by early humans and the associated development of cooking was the spark that radically changed human evolution.

The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.
