Physics – branch of science that studies matter [9] and its motion through space and time, along with related concepts such as energy and force. [10] Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics. According to physics, the ...
The history of thermodynamics is fundamentally interwoven with the history of physics and the history of chemistry, and ultimately dates back to theories of heat in antiquity. The laws of thermodynamics are the result of progress made in this field over the nineteenth and early twentieth centuries.
Modern physics is an effort to understand the underlying processes of the interactions of matter using the tools of science and engineering. In a literal sense, the term modern physics means up-to-date physics. In this sense, a significant portion of so-called classical physics is modern. [1]

Natural science can be divided into two main branches: physical science and life science (or biology). Social sciences: the study of human behavior in its social and cultural aspects. [1] Scientific knowledge must be grounded in observable phenomena and must be capable of being verified by other researchers working under the same conditions. [2]
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.
Biology – Science that studies life; Biochemistry – Study of chemical processes in living organisms; Biomechanics – Study of the mechanics of biological systems; Biometrics – Metrics related to human characteristics; Bionomics – Term with different meanings in ecology or economics – study of organisms interacting in their environments.
From a physics perspective, an organism is a thermodynamic system with an organised molecular structure that can reproduce itself and evolve as survival dictates. [21] [22] Thermodynamically, life has been described as an open system which makes use of gradients in its surroundings to create imperfect copies of itself. [23]
