Philosophy of physics is the study of the fundamental, philosophical questions underlying modern physics, the study of matter and energy and how they interact. Perhaps the main questions concern the nature of space and time, atoms and atomism, cosmology, the interpretation of the results of quantum mechanics, the foundations of statistical mechanics, causality, determinism, and the nature of physical laws. Classically, several of these questions were studied as part of metaphysics (for example, those about causality, determinism, and space and time). Today, the philosophy of physics is very close to and the most active subtopic within philosophy of science. Philosopher in Meditation (detail), by Rembrandt Philosophy is a field of study that includes diverse subfields such as aesthetics, epistemology, ethics, logic, and metaphysics, in which people ask questions such as whether God exists, whether knowledge is possible, and what makes actions right or wrong. ...

Matter is commonly defined as the substance of which physical objects are composed. ... Interaction is a kind of action which occurs as two or more objects have an effect upon one another. ... Space has been an interest for philosophers and scientists for much of human history, and hence it is difficult to provide an uncontroversial and clear definition outside of specific defined contexts. ...

In natural philosophy, atomism is the theory that all the objects in the universe are composed of very small, indestructible elements. ... // Cosmology, from the Greek: κοσμολογία (cosmologia, κόσμος (cosmos) world + λογια (logia) discourse) is the study of the Universe in its totality, and by extension, humanitys place in it. ... For a non-technical introduction to the topic, please see Introduction to Quantum mechanics. ... Statistical mechanics is the application of statistics, which includes mathematical tools for dealing with large populations, to the field of mechanics, which is concerned with the motion of particles or objects when subjected to a force. ... Although causality, the relationship between causes and effects, is often examined in the fields of philosophy, computer science, and statistics, it has a place in the study of physics as well. ... Determinism is the philosophical proposition that every event, including human cognition and action, is causally determined by an unbroken chain of prior occurrences. ... A physical law, scientific law, or a law of nature is a scientific generalization based on empirical observations of physical behavior. ...

The importance of philosophy of physics

Albert Einstein was extremely interested in the philosophical conclusions of his work, and the following two quotes explain a few of the more important reasons why this subject knowledge is important. Albert Einstein, photographed by Yousuf Karsh in 1948. ...

"I fully agree with you about the significance and educational value of methodology as well as history and philosophy of science. So many people today - and even professional scientists - seem to me like somebody who has seen thousands of trees but has never seen a forest. A knowledge of the historic and philosophical background gives that kind of independence from prejudices of his generation from which most scientists are suffering. This independence created by philosophical insight is - in my opinion - the mark of distinction between a mere artisan or specialist and a real seeker after truth." Methodology is a meta-knowledge. ... The history of science investigates the historical record of human events that are pertinent to the cultural context and the secular development of what is currently called science, namely, a body of empirical and theoretical knowledge, produced by a global community of researchers, making use of specific techniques for the... The philosophy of science is the branch of philosophy that studies the philosophical assumptions, foundations, and implications of science, including the formal sciences, natural sciences, and social sciences. ...

- Einstein to Robert A. Thornton, 7 December 1944, EA 61-574
"How does it happen that a properly endowed natural scientist comes to concern himself with epistemology? Is there no more valuable work in his specialty? I hear many of my colleagues saying, and I sense it from many more, that they feel this way. I cannot share this sentiment. ... Concepts that have proven useful in ordering things easily achieve such an authority over us that we forget their earthly origins and accept them as unalterable givens. Thus they come to be stamped as 'necessities of thought,' 'a priori givens,' etc. The path of scientific advance is often made impassable for a long time through such errors. For that reason, it is by no means an idle game if we become practiced in analyzing the long-commonplace concepts and exhibiting [revealing, exposing? -Ed.] those circumstances upon which their justification and usefulness depend, how they have grown up, individually, out of the givens of experience. By this means, their all-too-great authority will be broken."

Ernst Mach Ernst Mach (February 18, 1838 – February 19, 1916) was an Austrian-Czech physicist and philosopher and is the namesake for the Mach number and the optical illusion known as Mach bands. ...

Subjects in the philosophy of physics

An interpretation of quantum mechanics is an attempt to answer the question, What exactly is quantum mechanics talking about? The question has its historical roots in the nature of quantum mechanics itself which was considered as a radical departure from previous physical theories. ... The examples and perspective in this article or section may not represent a worldwide view. ... The philosophy of thermal and statistical physics is one of the major subdisciplines of the philosophy of physics. ...
