### stone brick:

Thermodynamic system
* All thermodynamic systems generate waste heat.
+ Thermodynamics
  * An example of a thermodynamic system is a stone brick. A brick is made up of many atoms which all have their own properties. All thermodynamic systems have two kinds of properties, extensive, and intensive. For the brick, the extensive properties are the ones you get by adding up all the atoms. Things like the volume, energy, mass, and charge are extensive because two of the same brick put together have twice as much mass as one brick. The intensive properties of the brick are the ones you get by looking at the average over all atoms. Things like temperature, pressure, and density are intensive because two of the same brick still has the same temperature as one brick alone.

### stone:

Achondrite
* Many achondrites resemble igneous rocks on Earth, especially basalt.
* Most achondrites are basalts or breccias of basalt fragments and look very much like Earth basalts.
* appear to have been chondritic before being altered by a heating or impact event.
* are also stony meteorites, but they are considered differentiated or reprocessed matter
  - among the rarest of stony meteorites
  - rocky, with no glass spherules, and resemble Earth lavas
  - stony meteorites that lack chondrules
* have different abbreviations all with A as initial letter
  - no chondrules
* show even greater signs of heating and differentiation than the ordinary chondrites.

Bladder stone
* are a significant health problem for many dogs and cats
  - calculuses
  - crystal masses made from minerals and proteins in urine
  - different than kidney stones
  - more common in elderly men with obstruction or lower UTIs
  - uncommon in the United Kingdom
* can also cause inflammation
  - develop in a period of weeks to months
* occur when there are high concentrations of minerals in the urine.

Calcium stone
* are clearly the most commonly occuring form of nephrolithiasis.
* occur two to three times more often in men than in women.

Calculus
* Most calculi are composed of calcium oxalate and the main factor in pathogenesis is hypercalciuria.
* are rocks.
* concerns patterns of continuous change.
* deals with determining the slope of functions.
* looks at rates of change over time.
* works by making visible the infinitesimally small.

### stone:

Caliche
* are rocks
  - soil
* chalky type soil, white in color and chemically composed of calcium carbonate.
* hard-water deposit on steroids.
* is calcium carbonate that has precipitated out of water infiltrating though the thin soil
  - present in soils that have little calcium
  - usually light-colored, and can occur as soft thin layers or hard thick beds
* mineral sandcasting.
* naturally occurring limestone deposit in southern Arizona deserts.
* reddish-brown to white layer found in many desert soils.

Capstone
* are part of walls
* maker of microturbines to generate electricity.
* switched network environment.

Cast stone
* resembles limestone or sandstone.
* simulates natural limestone.

### stone:

Chondrite
* All chondrites contain chondrules.
* Most chondrites contain a variety of different types of chondrules.
* Some chondrites appear to be from noncollisional origins, e.g., a small archaic accretion
  - are poor in volatiles, while others are rich in volatiles, such as water and carbon
* are almost as old as the Earth
  - meteorites
* are the most primitive meteorites known
  - oldest known rocks in the solar system
* are, by far, the most abundant type of stony meteorite.
* contain several forms of carbon, including diamonds older than our sun.
* generally show much cooler histories than other meteorites.
* have a composition that closely resembles that of the photosphere of the sun.
