Visual spectrum This site, closely coupled to The Natures of the Stars and The Hertzsprung- Russell HR Diagram , provides an introduction to the spectra of stars and allied celestial objects. Here we examine the principal way in which astronomers have learned so much about the stars. Spectra has been translated into Romanian. The visual spectrum Pass sunlight through a triangular prism or bounce it off the finely grooved surface of a compact audio disk and see it break merrily into a band of pure sparkling color, its “spectrum,” familiar in the colors of a rainbow, in light glittering from newly fallen snow, in the rings and haloes around a partly- clouded Sun and Moon, in the flash of a cut diamond, and in so many other facets of nature. The classic colors red, orange, yellow, green, blue, and violet connect in a seemingly infinite number of shades, one blending smoothly into the next. Together they constitute the “visual spectrum” or “optical spectrum” because it is the part of the full spectrum that is seen with the human eye. The rainbow is a natural spectrum caused by the refraction and reflection of sunlight through raindrops, and shows that sunlight consists of a continuous run – – a continuum — of colors from red to violet.

Interactions of an object with another object can be explained and predicted using the concept of forces, which can cause a change in motion of one or both of the interacting objects. An individual force acts on one particular object and is described by its strength and direction. The strengths of forces can be measured and their values compared. What happens when a force is applied to an object depends not only on that force but also on all the other forces acting on that object.
A static object typically has multiple forces acting on it, but they sum to zero.
Navigating dating and relationships as a Christian can be overwhelming, especially with so many ungodly influences bombarding our thinking today.
It requires precise photographic skill, carefully choreographed performance and a wild imagination. Light graffiti as an art is not yet a century old, a discipline born from photographic mistakes and years of experimentation. Just how good can light painting get? So set your shutter speed slow, grab a flashlight and prepare to experience the best light painting the world has to offer. The great Pablo Picasso experimented with light painting in his later days. Picasso stood in front of the camera, armed with a flashlight, and traced his style of imagery in the air before the shutter slammed shut.
The result was an illuminating set of photos that show the artist at work— a wild set of self portraits where this famed painter shared the focal point with his art. The dancers hold their pose, the lights are set and Breton outlines their forms with light calligraphy before the shutters close.

From Nature magazine The carbon clock is getting reset. Climate records from a Japanese lake are set to improve the accuracy of the dating technique, which could help to shed light on archaeological mysteries such as why Neanderthals became extinct. Carbon dating is used to work out the age of organic material — in effect, any living thing. The technique hinges on carbon , a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate.

By Eric Betz December 8, Simonne The dead cores of two stars collided million years ago in a galaxy somewhat far away. The collision was so extreme that it caused a wrinkle in space-time — a gravitational wave. That gravitational wave and the light from the stellar explosion traveled together across the cosmos. They arrived at Earth simultaneously at 6: Eastern on August But it was also the first-ever direct confirmation that gravity travels at the speed of light.
The Speed of Gravity We all know light obeys a speed limit — roughly , miles per second. But why should gravity travel at the same speed? Newton also thought gravity acted instantaneously. It changes with speed and in the presence of gravity. Creighton explains that in electromagnetism, when you shake an electron, it creates a change in the electric field that spreads out at the speed of light.
Gravity works the same way. Shake a mass and the change in the gravitational field — the gravitational wave — propagates at that same speed.
How could the universe expand faster than the speed of light? That seems impossible!
Keep up the good work! The mixers between sessions and at the end of the evening were an especially relaxed way to meet people. Would definitely try it again. Great way to meet someone. The event went very smoothly and was a lot of fun. I’m so happy that we both took a chance on LOVE!

Emission of Light An overview of light emission Light can be produced by matter which is in an excited state and as it will be shown excitation can come from a variety of sources. The atoms and molecules that make up matter typically emit light at characteristic energies. The light emission can be spontaneous or stimulated.
In spontaneous emission matter at a sufficiently high energy level can relax by emitting photons of a characteristic energy, this is the process which occurs in flames, or discharge lamps. This phenomenon is the process which gives rise to laser emission where you have many photons at the same wavelength and in phase with each other. A body at a given temperature also emits a characteristic spectrum of light called black body radiation. Consider an electric filament as current is applied to it.
As the electric current supplies energy to the filament and it heats up, it starts to glow red, and as it gets hotter it then turns orange and then white. Our filament will approximate a black body and as the filament gains energy from the electrical power it tries to equalize its energy with its surroundings by radiating its excess energy. It does this by emitting li ght starting first in the infrared and as the filament gets hotter or has more energy the radiation moves more into the visible spectrum.
For example Sunlight is due to the black body radiation characteristic of a body at approximately 5, K see graph below: The source of the excitation to produce light emission can come from a variety of sources.

Disturbances speed of radiation: radiometric dating of radioactive decay may belong to compare the change is to fit these three centuries of light? Isn’t dendrochronology accurate, beta, Assertion 1 .
Eat one of those and your tummy will curl right up! Seriously speaking, a favorite attack on radiometric dating involves dangling “horror stories” about gross errors before the reader, thus giving the impression that radiometric dating is totally unreliable. Woodmorappe , with his collection of some bad radiometric dates, must surely be the master of that technique.
Upon being presented with claims that radiometric dating is totally erroneous, a question naturally arises: If radiometric geochronology is half as bad as Woodmorappe’s list suggests, then how in the world did geologists ever arrive at a tight consensus for the official dates? Look at the various radiometric tables in use over the last 20 years or so and you will find, at least for the fossil-bearing strata, a remarkably tight agreement. Did the geochronologists throw darts to determine the accepted dates?

Hardware radar detector – is a passive receiver that does not block the signal to which it is set, but simply notify the driver of the presence in the field of the radar radio interference. This application works differently, it uses a database of hazards previously detected by other users. For example, if the application is informed about mobile ambush, it means that at this point can probably be mobile ambush.
Any user can add new hazard to shared database.
