Industry History
The field of physics has been around for centuries, with early pioneers such as Galileo Galilei and Isaac Newton making significant contributions to the field. However, it wasn't until the 20th century that physics truly began to flourish. In the early 1900s, Albert Einstein's theory of relativity revolutionized the field, followed by the development of quantum mechanics in the 1920s. These breakthroughs led to the development of new technologies such as nuclear power and the transistor, which have had a profound impact on society. In recent years, physicists have continued to make significant advancements in fields such as astrophysics, particle physics, and quantum computing. In the United States, the field of physics has been heavily influenced by government funding, particularly through agencies such as the National Science Foundation and the Department of Energy. This funding has enabled physicists to make significant contributions to fields such as materials science, biophysics, and renewable energy.

About this classification
This page represents a commercial Extended NAICS industry classification used for business targeting, industry research, data analysis, and company classification. It is not an official U.S. Census Bureau NAICS code. Its parent industry is an official NAICS classification defined by the U.S. Census Bureau. Classifications are reviewed regularly by SICCODE.com's Classification Review Team.
SICCODE.com classifies companies under both Extended NAICS and Extended SIC. A company may appear in both classification systems, so company counts should not be added together without deduplication.
