### activity | measurement:

Calorimetry
* Calorimetries are measurements.
* is the empirical basis of the idea of quantity of heat transferred in a process
  - quantification of the heat released from metabolism
  - science of measuring heat
  - study of heat
* seems be the safe method to see the excess energy if there is any.
* technique that measures the heat evolved or absorbed during some process
  - which measures heat changes by monitoring temperature changes

Colorimetric analysis
* qualitative analysis
* recognized method for reliable testing of water samples.

### activity | measurement | densitometry:

Bone densitometry
* involves an extremely small dose of radiation.
* is an X-ray like test that quickly and accurately measures the density of bone
  - instant snapshot of bone status
* is the most accurate clinical predictor of osteoporosis
  - test for predicting and diagnosing osteoporosis
  - used to determine osteoporosis in post menopausal women
* measures the calcium content of the bones, a rough measure of bone thickness.

Field measurement
* have negative values
* use laws.

Mass measurement
* are independent of changes in density and temperature.
* provide an essential link to theoretical models of galaxy formation and evolution.

Performance measurement
* begins when the leaders of an organization determine their strategic focus.
* encompasses an assessment of how effectively issues are reported.
* is an integral part of healthcare
  - of the results, outcomes, and efficiency of services or programmes
* is the linchpin of the value capture process
  - process corporations use to determine how well they re doing
* type of evaluation that is used in many industries.

Photometry
* Photometries are measurements.
* tries to even the field to help one see the planet directly.

Quantification
* is achieved by measuring the release of radiolabelled galactose
  - an important step in understanding and managing complex processes
  - restrictions
* refers to a tendency to emphasize quantity rather than quality.
* ubiquitous phenomenon, both in logic and language.

Quantitative analysis
* Quantitative analyses consist of observations.
* are chemical analysises
* fundamental part of understanding and managing ecological systems.
* has the general purpose of summarising and relating data.
* is important in physiology and medicine
  - used to maximize profit and minimize risk
* qualitative analysis
* uses analytic reasoning and logical models.

Radiation measurement
* are at normal background levels above ground, at the surface.
* give information
  - specific information

### activity | measurement:

Surveying
* can involve activities such as asking people questions during structured interviews.
* dynamic process of people taking measurements of an ever-changing world.
* is discussed as a particularly important type of subscientific mathematics
  - real world application of trigonometry
* is one of many educational strategies that teachers can use to elicit ideas
  - the most accurate methods of data capture
  - the measurement of the physical characteristics of a parcel of land
* wide and varied field.
+ Parsec: Astronomical distances :: Units of length
  * Surveying provides an everyday example of parallax. Go outside and look at a distant object. Hold your hand out with one finger raised and close one eye. Then close that eye and open the other without moving your arm. Now, move your finger to block that eye's line of sight. The two positions your finger was at  can be used to find the distance from the object.

Temperature measurement
* are also a necessary step in determining the masses of the clusters
  - good examples of interval scales
* critical variable for microwave power control and recipe conformance.
* define the depth of the thermocline.
