So by observing how much light is missing at these characteristic wavelengths, we can tell not only what elements are in the Sun's atmosphere, but even their concentrations. And the same idea can be applied to study other stars. Make a spectral rainbow, see what's missing,

As we face fear in these times, and fear is all around us, we also have anti-fear. It's hard to imagine or measure. The background radiation is simply too static to be able to be seen under the normal spectral analysis.

Sarah Parcak
American Scientist
Archaeologists gave the military the idea to use aerial photographs for spying and field survey. We are fortunate that the spatial and spectral resolutions of the imagery available to us are so broadly useful for archaeology.

Richard Corliss
American Writer
Interstellar' may never equal the blast of scientific speculation and cinematic revelation that was Stanley Kubrick's '2001: A Space Odyssey,' but its un-Earthly vistas are spectral and spectacular.
Quote examples
Pieter Zeeman
Dutch Physicist
On the basis of Lorentz's theory, if we limit ourselves to a single spectral line, it suffices to assume that each atom (or molecule) contains a single moving electron.
Quote examples
Timothy Morton
English Philosopher
The waste products in Earth's crust are also the human in this expanded, spectral sense. One's garbage doesn't go 'away' - it just goes somewhere else.
Quote examples
Joseph Conrad
Polish Novelist
How does one kill fear, I wonder? How do you shoot a specter through the heart, slash off its spectral head, take it by its spectral throat?
Quote examples
John Berger
English Artist
Modern thought has transferred the spectral character of Death to the notion of time itself. Time has become Death triumphant over all.
Quote examples
Ronald Coase
British Economist
Technology is at a point where we should allow multiple parties to occupy the same spectral space.

Johannes Stark
Physicist
The emitters of the spectral series are without exception single atoms, not compounds of atoms.

German Artist
What appears spectral today will be natural tomorrow.
