Physical science is a branch of natural science that studies non-living systems, in contrast to life science. It in turn has many branches, each referred to as a "physical science", together is called the "physical sciences".

👉 Physical sciences in the context of Physicalism
In philosophy (metaphysics), physicalism or physical logicism is the view that "everything is physical", that there is "nothing over and above" the physical, or that everything supervenes on the physical. It is opposed to idealism, according to which the world arises from the mind. Physicalism is a form of ontological monism—a "one substance" view of the nature of reality, unlike "two-substance" (mind–body dualism) or "many-substance" (pluralism) views. Both the definition of "physical" and the meaning of physicalism have been debated. Physicalism is often treated as equivalent to naturalism but there are important distinctions between them.
Physicalism is closely related to materialism, and has evolved from materialism with advancements in the physical sciences in explaining observed phenomena. The terms "physicalism" and "materialism" are often used interchangeably, but can be distinguished on the basis that physics describes more than just matter. Physicalism encompasses matter, but also energy, physical laws, space, time, spacetime, exotic matter, structure, physical processes, information, state, and forces, among other things, as described by physics and other sciences, all within a monistic framework.

Physical sciences in the context of Nanking
Nanjing is the capital of Jiangsu, a province in East China. The city, which is located in the southwestern corner of the province, has 11 districts, an administrative area of 6,600 km (2,500 sq mi), and as of 2021 a population of 9,423,400.Situated in the Yangtze River Delta, Nanjing has a prominent place in Chinese history and culture, having served as the capital of various Chinese dynasties, kingdoms and republican governments dating from the 3rd century to 1949, and has thus long been a major center of culture, education, research, politics, economy, transport networks and tourism, being the home to one of the world's largest inland ports. The city is also one of the fifteen sub-provincial cities in the People's Republic of China's administrative structure, enjoying jurisdictional and economic autonomy only slightly less than that of a province. It has also been awarded the title of 2008 Habitat Scroll of Honor of China, Special UN Habitat Scroll of Honor Award and National Civilized City. Nanjing is also considered a Beta (global second-tier) city classification, together with Chongqing, Hangzhou and Tianjin by the Globalization and World Cities Research Network, and ranked as one of the world's top 100 cities in the Global Financial Centres Index.
As of 2021, Nanjing has 68 institutions of higher learning, including 13 double-first-class universities, ten 111-plan universities, eight 211 universities, and 97 academies. Nanjing University, which has a long history, is among the world's top 10 universities ranked by the Nature Index. The ratio of college students to the total population ranks No.1 among large cities nationwide. Nanjing has the fifth-largest scientific research output of any city in the world. As of 2024, it has been ranked as the world's second most prolific scientific research center in earth and environmental sciences and the world's third most prolific scientific research center in chemistry and physical sciences, according to the Nature Index.
Physical sciences in the context of Spectrum (physical sciences)
In the physical sciences, spectrum describes any continuous range of either frequency or wavelength values. The term initially referred to the range of observed colors as white light is dispersed through a prism — introduced to optics by Isaac Newton in the 17th century.
The concept was later expanded to other waves, such as sound waves and sea waves that also present a variety of frequencies and wavelengths (e.g., noise spectrum, sea wave spectrum). Starting from Fourier analysis, the concept of spectrum expanded to signal theory, where the signal can be graphed as a function of frequency and information can be placed in selected ranges of frequency. Presently, any quantity directly dependent on, and measurable along the range of, a continuous independent variable can be graphed along its range or spectrum. Examples are the range of electron energy in electron spectroscopy or the range of mass-to-charge ratio in mass spectrometry.
Physical sciences in the context of Royal College of Science for Ireland
The Royal College of Science for Ireland (RCScI) was an institute for higher education in Dublin which existed from 1867 to 1926, specialising in physical sciences and applied science. It was originally based on St. Stephen's Green, moving in 1911 to a purpose-built "Royal College of Science" building on Merrion Street, now known as Government Buildings. In 1926 it was absorbed into University College Dublin (UCD) as the faculty of Science and Engineering.
Physical sciences in the context of Wiley-Blackwell (publisher)
Wiley-Blackwell is an international scientific, technical, medical, and scholarly publishing business of John Wiley & Sons. It was formed by the merger of John Wiley & Sons Global Scientific, Technical, and Medical business with Blackwell Publishing in 2007.
Wiley-Blackwell is now an imprint that publishes a diverse range of academic and professional fields, including biology, medicine, physical sciences, technology, social science, and the humanities.
