Parent Category: Science Science (from the Latin scientia,
meaning "knowledge" or "knowing") is the effort to discover, and
increase human understanding of how the physical world works.
Using controlled methods, scientists collect data in the form of
observations, records of observable physical evidence of natural
phenomena, and analyze this information to construct theoretical
explanations of how things work. Knowledge in science is gained
through research. The methods of scientific research include the
generation of hypotheses about how natural phenomena work, and
experimentation that tests these hypotheses under controlled
conditions. The outcome or product of this empirical scientific
process is the formulation of theory that describes human
understanding of physical processes and facilitates prediction.
Lavoisier says, "... the impossibility of separating the
nomenclature of a science from the science itself is owing to
this, that every branch of physical science must consist of
three things: the series
