Spectroscopy
* Covers new developments and research in spectroscopic technology.
* allows astronomers to determine the chemical composition of stars
  - study of temperature, velocity, rotation, and composition
* breaks up the sunlight reflected from a satellite into the light's individual colors.
* comprises absorption, emission, or scattering.
* delves into the interaction of light, visible and invisible, with matter.
* gathers information about the composition and motion of astronomical objects.
* helps to explain basic mechanisms and tailor materials for different applications.
* involves measuring the interaction of electromagnetic radiation with chemical species
  - the interaction of light with matter
* is also a useful technique
  - at the heart of astrophysical inference
  - chemical analysises
  - different from imaging
* is more than group frequencies and chemical shifts
  - obtaining data
  - one of the most important tools of the astronomer
  - second to photography with regards to importance
* is the analysis of the intensity of light at each wavelength
  - basis of most astrophysics and most active research in astronomy
  - measurement of the response of a material as a function of frequency
  - most powerful tool of observational astronomy
  - observation and interpretation of spectra
* is the study of electromagnetic radiation
  - something using spectra
  - spectra, ie characteristic wavelengths or colours
* is the study of the component wavelenghts of light after they have been dispersed
  - interaction of light and matter
  - interactions between light energy and matter
  - unique frequencies of light that atoms and molecules emit orabsorb
* measures the intensities of light at different wavelengths
  - type of chemical bonds which exist in a substance by the light it absorbs
* method that separates a star's light into a bar of several different colors.
* plays an integral part in modern forensic science in the identification of substances.
* qualitative analysis
* reveals chemical composition of stars
  - the composition and redshift of the supernova
* scientific measurement technique.
* shows the presence of water ice, which probably covers rocky silicate cores.
* small field.
* uses hundreds of filters.
* versatile technique for infrared sampling.
* very useful technique for chemists.
* vital tool for astronomers and provides a wealth of information.
* way of essentially getting living chemistry.
+ Organic chemistry, Spectroscopy: Chemistry
  * Spectroscopy is the study of the interactions between light energy and matter. We are able to see colors because of energy absorption by organic and inorganic compounds. When a plant undergoes photosynthesis, it traps energy from the sun, and this is an example of an interaction between energy and organic compounds.

Sharksucker
* are known to follow divers and attack to divers' legs.
* have no known predators.

Sporulation
* begins with a reorganisation of the cell cycle.
* common mode of mold dispersion.
* develops on the necrotic areas under humid conditions.
* involves chromosome distribution and spore morphogenesis.
* is complex and differs widely among the fungi
  - reduced somewhat by cooler temperatures
  - reproduction
  - the formation of spores that occurs in bread mold, mushrooms, mosses, and ferns
* occurs during cool, moist weather
  - from lesions whether they are on leaflets or on stems
  - on the underside of leaves and appears as brown to gray
  - throughout the year, peaking during fall and winter
* proceeds when conditions are no longer favorable for growth.
* starts at the embryo end and moves along the suture of the grain.
