The stars and planets, believed to represent gods, were often worshipped. Early civilizations dating before 3000 BCE, such as the Sumerians, ancient Egyptians, and the Indus Valley Civilisation, had a predictive knowledge and a basic awareness of the motions of the Sun, Moon, and stars. Main article: History of astronomy Ancient Egyptian astronomy is evident in monuments like the ceiling of Senemut's tomb from the Eighteenth Dynasty of Egypt.Īstronomy is one of the oldest natural sciences. The expansion of the universe according to the Big Bang theory in physics History For example, advances in the understanding of electromagnetism, solid-state physics, and nuclear physics led directly to the development of new products that have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons advances in thermodynamics led to the development of industrialization and advances in mechanics inspired the development of calculus. New ideas in physics often explain the fundamental mechanisms studied by other sciences and suggest new avenues of research in these and other academic disciplines such as mathematics and philosophy.Īdvances in physics often enable new technologies. Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. Over much of the past two millennia, physics, chemistry, biology, and certain branches of mathematics were a part of natural philosophy, but during the Scientific Revolution in the 17th century these natural sciences emerged as unique research endeavors in their own right. Physics is one of the oldest academic disciplines and, through its inclusion of astronomy, perhaps the oldest. A scientist who specializes in the field of physics is called a physicist. Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves.
