Physics is a branch of science in which the primary objects of study are matter and energy.These topics were discussed by philosophers across many cultures in ancient times, but they had no means to distinguish causes of natural phenomena from superstitions.
The nature of the history of science is a topic of debate (as is, by implication, the definition of science itself). The history of science is often seen as a linear story of progress [27] but historians have come to see the story as more complex.

where the variables refer to Friedmann–Einstein universe, where is defined in the equations, is the speed of light, is the scale factor, is the radius of the universe (measured in light years) and its maximal value, is the mean density of matter, is time and the age of the universe (last line, measured in years), and is the Einstein's gravitational constant.
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 a fundamental strand in the history of physics, the history of chemistry, and the history of science in general. Due to the relevance of thermodynamics in much of science and technology, its history is finely woven with the developments of classical mechanics, quantum mechanics, magnetism, and chemical kinetics, to more distant applied fields such as ...
The book was produced specifically for women with an interest in scientific writing and inspired a variety of similar works. [63] These popular works were written in a discursive style, which was laid out much more clearly for the reader than the complicated articles, treatises, and books published by the academies and scientists.
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.
