A physical system is a collection of physical objects under study. [1] The collection differs from a set : all the objects must coexist and have some physical relationship. [ 2 ] In other words, it is a portion of the physical universe chosen for analysis.
Physical cosmology – the study of the largest-scale structures and dynamics of the universe and is concerned with fundamental questions about its formation and evolution. Planetary science – the scientific study of planets (including Earth), moons, and planetary systems, in particular those of the Solar System and the processes that form them.
Physics – natural and physical science could involve the study of matter [4] and its motion through space and time, along with related concepts such as energy and force. [5] More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. [a] [6] [7] Branches of physics
Physics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. [1] Physics is one of the most fundamental scientific disciplines. [2] [3] [4] A scientist who specializes in the field of physics is called a physicist.
atmospheric physics is the application of physics to the study of the atmosphere; space physics is the study of plasmas as they occur naturally in the Earth's upper atmosphere (aeronomy) and within the Solar System; biophysics, studying the physical interactions of biological processes; chemical physics, the science of physical relations in ...
Oceanography – The study of the physical and biological aspects of the ocean. Physics – study of matter and its motion through spacetime, along with related concepts such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.
Ecological energetics is the quantitative study of the flow of energy through ecological systems. It aims to uncover the principles which describe the propensity of such energy flows through the trophic, or 'energy availing' levels of ecological networks. In systems ecology the principles of ecosystem energy flows or "ecosystem laws" (i.e ...
In many respects, the foundational concepts of Earth System science can be seen in the natural philosophy 19th century geographer Alexander von Humboldt. [23] In the 20th century, Vladimir Vernadsky (1863–1945) saw the functioning of the biosphere as a geological force generating a dynamic disequilibrium, which in turn promoted the diversity ...
