A Quote by Robert Bunsen
At the moment I am occupied by an investigation with Kirchoff which does not allow us to sleep. Kirchoff has made a totally unexpected discovery, inasmuch as he has found out the cause for the dark lines in the solar spectrum and can produce these lines artificially intensified both in the solar spectrum and in the continuous spectrum of a flame, their position being identical with that of Fraunhofer's lines. Hence the path is opened for the determination of the chemical composition of the Sun and the fixed stars.

For example, some stars put out large amounts of energy in the infrared part of the spectrum, so that this can produce a different relative magnitude rating than using light energy from the middle of the spectrum.
You are not only the solar spectrum with the seven luminous colours, but the sun himself, that illumines, warms, and revivifies! This is what you are, and I am the lowly woman that adores you.
I argue that science would be much richer if it were multisensory. The problem with instrumentation is that instruments, unlike our senses, can be monosensory. Since the discovery of the electromagnetic spectrum - which is really the discovery that all energy coming from something has a wave form - in theory we could image anything along that spectrum. In fact, we don't, because only certain parts of the spectrum have been instrumentalized. But the new thing is computerization. You can take all the data, the measurement of the frequencies, and transform it into an image.
In the last four days I have got the spectrum given by Tantalum, Chromium, Manganese, Iron, Nickel, Cobalt, and Copper and part of the Silver spectrum. The chief result is that all the elements give the same kind of spectrum, the result for any metal being quite easy to guess from the results for the others. This shows that the insides of all the atoms are very much alike, and from these results it will be possible to find out something of what the insides are made up of.
The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum.
A full-spectrum approach to human consciousness and behavior means that men and women have available to them a spectrum of knowing - a spectrum that includes, at the very least, the eye of flesh, the eye of mind, and the eye of spirit.
The persons who constitute the natural aristocracy, are not found in the actual aristocracy, or, only on its edge; as the chemicalenergy of the spectrum is found to be greatest just outside of the spectrum.
Water in swimming pools changes its look more than in any other form its colour can be man-made and its dancing rhythms reflect not only the sky but, because of its transparency, the depth of the water as well. If the water surface is almost still and there is a strong sun, then dancing lines with the colours of the spectrum appear everywhere.
Autism's a very big spectrum. At one end of the spectrum, Einstein would probably be labeled autistic, Steve Jobs, half of Silicon Valley, you know, Van Gogh. And at the other end of the spectrum, you got much more severe handicaps where they never learn to speak.
The electronic spectrum is the only natural resource in which there's no such thing as private property rights. You can't own a piece of the spectrum.
The reality is that race in the United States operates on a spectrum from black to white. Doesn't mean that people who are in between don't experience racism, but it means that the closer you are to white on that spectrum, the better off you are. And the closer to black that you are on that spectrum, the worse off your are.
It was regarded as a responsibility of the BBC to provide programs which have a broad spectrum of interest, and if there was a hole in that spectrum, then the BBC would fill it.
The neo-cons constitute a radical reactionary fringe of the planning spectrum, but the spectrum is narrow.
The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum - even encourage the more critical and dissident views. That gives people the sense that there's free thinking going on, while all the time the presuppositions of the system are being reinforced by the limits put on the range of the debate.
I'm an advocate for a full spectrum of energy policy, but we're never going to get there with solar cells that are going to power this country.
The description of right lines and circles, upon which geometry is founded, belongs to mechanics. Geometry does not teach us to draw these lines, but requires them to be drawn.
