The principle of natural selection is neutral with respect to the mechanism by which inheritable changes occur in organisms (most commonly thought to be due to mutation of genes and reorganization of genomes), but proposes that those forms which have become so modified as to be better adapted to the existing environment have tended to survive and leave similarly adapted descendants, while those less perfectly adapted have tended to die out through lack of fitness for the environment, thus resulting in the survival of the fittest. See Darwinism.

    Natural system (Bot. & Zo["o]l.), a classification based upon real affinities, as shown in the structure of all parts of the organisms, and by their embryology.

Douglas Harper's Etymology Dictionary

1580s, "natural science," from physic in sense of "natural science." Also see -ics. Based on Latin physica (neuter plural), from Greek ta physika, literally "the natural things," name of Aristotle's treatise on nature. Specific sense of "science treating of properties of matter and energy" is from 1715.\n


n. The branch of science concerned with the study of properties and interactions of space, time, matter and energy. vb. (en-third-person singular of: physic)


n. the science of matter and energy and their interactions [syn: physical science, natural philosophy]


Physics (from , from phúsis "nature" ) is the natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. One of the most fundamental scientific disciplines, the main goal of physics is to understand how the universe behaves.

Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Over the last two millennia, physics was a part of natural philosophy along with chemistry, biology, and certain branches of mathematics, but during the scientific revolution in the 17th century, the natural sciences emerged as unique research programs in their own right. Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the fundamental mechanisms of other sciences while opening new avenues of research in areas such as mathematics and philosophy.

Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs. For example, advances in the understanding of electromagnetism or nuclear physics led directly to the development of new products that have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization, and advances in mechanics inspired the development of calculus.

Physics (Aristotle)

The Physics ( Greek: Φυσικὴ ἀκρόασις Phusike akroasis; Latin: Physica, or Physicae Auscultationes, meaning " lectures on nature") of Aristotle is one of the foundational books of Western science and philosophy. As Martin Heidegger once wrote;

Bertrand Russell, however, says of Physics and On the Heavens that they were:

It is a collection of treatises or lessons that deal with the most general (philosophical) principles of natural or moving things, both living and non-living, rather than physical theories (in the modern sense) or investigations of the particular contents of the universe. The chief purpose of the work is to discover the principles and causes of (and not merely to describe) change, or movement, or motion (κίνησις kinesis), especially that of natural wholes (mostly living things, but also inanimate wholes like the cosmos). In the conventional Andronicean ordering of Aristotle's works, it stands at the head of, as well as being foundational to, the long series of physical, cosmological and biological treatises, whose ancient Greek title, τὰ φυσικά, means "the [writings] on nature" or " natural philosophy".

Physics (band)

Physics was an instrumental band from San Diego, California, USA started by John Goff and Denver Lucas in late 1993 out of the ashes of Johnny Superbad & the Bulletcatchers and closely involved with Crash Worship. Featuring a rotating cast of musicians from the San Diego experimental underground but mainly composed of Denver Lucas on drums, Jfre Coad on synths, John Goff, Jason Soares, Rob Crow, and Travis Nelson on guitars. Also Ryan Jencks on guitar/violin/visuals, and Matt Lorenz on live film collage/projections. This early incarnation came to be known as the "Black Period". Mainly inspired by theories in quantum theory and Eastern Mysticism, Physics was musically influenced by Krautrock, Minimalism, early Doom/ Drone and Electronic Kosmische, though were often associated with the Math Rock genre. After the untimely death of Denver Lucas in the mid 90s, the Physics personnel underwent numerous changes until resulting in Will Goff on bass and Cameron Jones on drums which was later known as the "Gray Period" then ultimately the "White Period".

After Physics dissolved in 2000, Jason Soares and Jeff Coad went on to form the more electronic-based Aspects Of Physics also with Matt Lorenz. Will and John Goff went on to form the electronic band SSI. Rob Crow started Pinback (co-led by Zach Smith from Three Mile Pilot) and Ryan Jencks continued playing with Crash Worship while simultaneously starting / playing with a myriad of experimental Industrial noise and metal projects including Dispirit

In 2015 coinciding with the release of the documentary "It's Gonna Blow!!! San Diego's Music Underground 1986-1996", Physics reformed in select cities including Portland and Los Angeles for the film premiere featuring John, Jason Rob on guitars. Will, Jfre, on synths and Cameron on drums.

The editor-in-chief of Physics is Gene D. Sprouse. It highlights papers in Physical Review Letters and the Physical Review family of journals. The magazine was established in 2008.

Usage examples of "physics".

Through its principle of relativity, the special theory of relativity declares a democracy of observational vantage points: the laws of physics appear identical to all observers undergoing constant-velocity motion.

There are other physicists, however, who are deeply unsettled by the fact that the two foundational pillars of physics as we know it are at their core fundamentally incompatible, regardless of the ultramicroscopic distances that must be probed to expose the problem.

But as shall become clear, when seen in its proper context, string theory emerges as a dramatic yet natural outgrowth of the revolutionary discoveries of physics during the past hundred years.

I hope that, by explaining the major achievements of physics going back to Einstein and Heisenberg, and describing how their discoveries have grandly flowered through the breakthroughs of our age, this book will both enrich and satisfy this curiosity.

For science students and teachers, I hope this book will crystallize some of the foundational material of modern physics, such as special relativity, general relativity, and quantum mechanics, while conveying the contagious excitement of researchers closing in on the long-sought unified theory.

Since the theory unifies the laws of the large and of the small, laws that govern physics out to the farthest reaches of the cosmos and down to the smallest speck of matter, there are many avenues by which one can approach the subject.

The problem is this: There are two foundational pillars upon which modern physics rests.

This quixotic quest isolated Einstein from the mainstream of physics, which, understandably, was far more excited about delving into the newly emerging framework of quantum mechanics.

And a sizeable part of the physics and mathematics community is becoming increasingly convinced that string theory may provide the answer.

Although it would be hard to explain the properties of a tornado in terms of the physics of electrons and quarks, I see this as a matter of calculational impasse, not an indicator of the need for new physical laws.

The laws of physics that each deduces from the experiments will likewise be identical.

With an audacious step in the service of scientific hegemony, Newton united the physics governing both heaven and earth and declared the force of gravity to be the invisible hand at work in each realm.

He felt that probability was turning up in fundamental physics because of a subtle version of the reason it turns up at the roulette wheel: some basic incompleteness in our understanding.

Heisenberg discovered the uncertainty principle, physics turned a sharp corner, never to retrace its steps.

That is, without the strong force, physics would change under the kinds of shifts of color charges indicated above.
