### science | natural science:

Physics
* allows an object about as heavy as the sun to be stable in only a very few sizes.
* applies to biology at all levels, from the basics of biosystems to biomedical engineering
  - everyday life
* attempts to answer fundamental questions about the nature and origin of our universe
  - describe the fundamental nature of the universe and how it works
* begins by considering the simplest phenomena apparent in everyday life
  - with measurement
* call it the quantum field.
* concerns itself heavily with the mechanics of events in nature.
* consists of many research fields and each research field has a wide variety of contents.
* contains models that are only approximations of reality.
* continues to be one of the most active an important science.
* deals with concepts such as mass, length, time and energy
  - efficient and material causes, metaphysics with formal and final causes
  - realms of space from the size of less than a proton to the size of the universe
  - terribly complex objects even at the fundamental particle level
* deals with the causes and controls of movement
  - combination of matter and energy
  - fundamental phenomena of nature, space, time, matter and energy
  - laws of nature and matter
  - universal and the subatomic, with motion, heat, light, electricity
* defines a uniform straight motion, when the forces on an object are in equilibrium.
* describes it's inner workings.
* dictates that signals degrade over distance.
* encompasses a broad range of concepts, ideas, problems, and solutions
  - large body of knowledge that unifies our understanding of nature
* forms a foundation for all the physical and biological sciences.
* forms the basis for all other sciences, including chemistry, biology, geology, oceanography
  - most of the natural and applied sciences and technology
* forms the foundation of most of today's rapidly changing technologies
  - upon which most other fields of science rest
* helps develop many important characteristics of any great mind.
* is everywhere
  - thus the continuous critique of quantitative laws
* lies behind many everyday phenomena.
* lives in the works of the great physicists.
* looks at how nature is made, and how different fields of nature relate to each other.
* models time as real numbers.
* operates by universal laws, biology by whatever works at the time.
* plays a basic role in all science and engineering disciplines
  - role in our lives, everyday
* release an electrical charge from.
* relies heavily on mathematics.
* represents humankind's attempt to gain a fundamental understanding of how nature works.
* seeks to explain the natural processes of the physical world
  - understand all natural phenomena in terms of fundamental laws
* starts with observation.
* states that like attracts like.
* studies how matter and energy interact.
* teaches that energy sources leave telltale signatures in the form of exhaust or radiation.
* treats the contingent properties of nature.
* tries to get to the roots of all physical phenomena.
* underpins all sciences
  - much of modern medicine and biology
+ Natural sciences
+ Physics, What is physics?
  * Physics studies very large things, and very small things. For instance, physicists can study stars, planets and galaxies but could also study small pieces of matter, such as atoms and electrons. They may also study sound, light and other waves. As well as that, they could examine energy, heat and radioactivity, and even space and time.

### science | natural science | physics:

Atomic physics
* describe the properties of atoms and their interaction with particles and fields.
* examines the structure, properties, and behavior of the atom.
* reduces to subatomic physics.
* studies the electron shells of atoms
  - interaction between electrons and the nucleus of an atom
