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.

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.

American Writer

Pieter Zeeman

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.

Dutch Physicist

Timothy Morton

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.

English Philosopher

Joseph Conrad

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?

Polish Novelist

John Berger

Modern thought has transferred the spectral character of Death to the notion of time itself. Time has become Death triumphant over all.

English Artist

Ronald Coase

Technology is at a point where we should allow multiple parties to occupy the same spectral space.

British Economist

Johannes Stark

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

Physicist

Franz Marc

What appears spectral today will be natural tomorrow.

German Artist

Karl Kraus

Science is spectral analysis. Art is light synthesis.

Austrian Writer

Used to evoke mystery or eeriness in literature, often in gothic or horror genres.

Literary Ghostliness

In many cultures, spectral beings are related to folklore and tales meant to impart moral lessons.

Cultural Spooks

Conveys a sense of vagueness or indistinctness, like an unclear figure or vision.

Visual Uncertainty

Mainly used in physics and art to describe phenomena related to the visible spectrum.

Color Spectrum

In science, 'spectral' implies precise categorization by wavelength or frequency.

Scientific Precision

In photography, spectral light can affect color balance and mood.

Photographic Imagery

In data science, spectral displays help visualize complex datasets visually.

Data Visualization

Spectral analysis cuts across fields from astronomy to medicine for investigative purposes.

Multidisciplinary Research

In music production, spectral refers to clear representation of sound frequencies.

Audio Clarity

Spectral analysis in acoustics can help identify noise pollution sources.

Sound Analysis

Refers to the complete range of audible frequencies a sound contains.

Frequency Range

 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,

 The court accepted all kinds of dubious evidence, including so-called “spectral evidence” in which the girls began raving when supposedly touched by invisible ghosts. Complicating matters further, many of the jurors in the trials

What really happened...

 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.

 that generates a star's heat and energy and causes it to shine. Stars are categorized by a number of characteristics. One of these classifications is by surface temperature called spectral classes.
