The video signal is amplified and then switched, in synchronism with the three ultraviolet light sources which are sequenced by the rotating mirror so that during one-twentieth of a second only one wavelength, corresponding to red, green, or blue, is seen.

The human body -- he pointed out, for example -- required 33 units of blue light.

`` The white colonnaded, cedar-roofed Southern mansion is directly traceable via the grey and buff stone of grey-skied England to the golden stucco of one particular part of the blue South, the Palladian orbit stretching out from Vicenza: the old mind of Andrea Palladio still smiles from behind many an old rocking chair on a Southern porch, the deep friezes of his architectonic music rise firm above the shallower freeze in the kitchen, his feeling for light and shade brings a glitter from a tall mint julep, his sense of columns framing the warm velvet night has brought together a million couple of mating lips ''.

There wasn't much light in the blue dark, but I could see her well.

Owing to its strong radioactivity, actinium glows in the dark with a pale blue light, which originates from the surrounding air ionized by the emitted energetic particles.

The ideal grade is called " Deep Siberian " and has a primary purple hue of around 75 – 80 %, with 15 – 20 % blue and ( depending on the light source ) red secondary hues.

It turns blue in natural sunlight and any other partially or wholly ultraviolet light source.

* δ Antliae is a blue double star 481 light years away.

Shining blue light on a cell containing PAC activates it and abruptly increases the rate of conversion of ATP to cAMP.

For example, PAC expression in certain neurons has been shown to alter the grooming behavior in fruit flies exposed to blue light.

The video for " Takes A Little Time " was a new direction for Grant ; with a blue light filter, acoustic guitar, the streets and characters of New York City, and a plot, Grant was re-cast as an adult light rocker.

In 1895 a shaft of blue light served to indicate the presence of Banquo's spirit.

Nations that have an FTA with Chile appear in dark blue, those that have not ratified a negotiated FTA in light blue, and those in FTA negotiations in purple.

However, it does absorb slightly more red light than blue, giving large volumes of water a bluish tint ; increased scattering of blue light due to fine particles in the water shifts the blue color toward green, for a typically cyan net color.

Carolina debuted the alternate light blue jersey for one game at home against the Tampa Bay Buccaneers in 2002.

The Panthers have worn the light blue jersey a few times on the road when the home team has chosen to wear white due to the heat, as the light blue uniforms are more comfortable in the heat than black.

The moon had sunk below the black crest of the mountains and the land, seen through eyes that had grown accustomed to the absence of light, looked primeval, as if no man had ever trespassed before.

He fled through the door and down the steps, running, and the men grunted and followed, pushing Lester to one side where he backed against the wall with the sleeve of his jacket raised before his eyes to shut out the light.

This light did not penetrate very far back into the hall, and my eyes were hindered rather than aided by the dim daylight entering through the fan vents when I tried to pick out whatever might be lying, or squatting, on the floor below.

But actually these accounts reveal the supernatural powers that the masters were in fact supposed to possess, as well as the extreme degree of popular credulity: `` Hwang Pah ( O Baku ), one day going up Mount Tien Tai which was believed to have been inhabited by Arhats with supernatural powers, met with a monk whose eyes emitted strange light.

Richard's dark eyes came up and seemed for the tiniest moment to reflect sharp light.

This time B'dikkat smiled pleasantly at the little head which had grown out of Mercer's thigh -- a sleeping child's head, covered with light hair on top and with dainty eyebrows over the resting eyes.

It has rudimentary eyes covered in skin which are probably limited to discerning differences in light intensity.

The crew performed the Apollo light flash experiment, or ALFMED, to investigate " light flashes " that were seen by the astronauts when the spacecraft was dark, regardless of whether or not their eyes were open, on Apollo lunar flights.

: L, is the love light in your eyes

Additionally, the improper development of the RPE, which in normal eyes absorbs most of the reflected sunlight, further increases glare due to light scattering within the eye.

Blind people with undamaged eyes may still register light non-visually for the purpose of circadian entrainment to the 24-hour light / dark cycle.

This was not, as may be thought, a momentary transient phenomenon: for it continued several hours together visible to our eyes, and brighter than the sun ;; the light of which would have eclipsed it, had not this been stronger.

Light-colored dachshunds can sport amber, light brown, or green eyes ; however, kennel club standards state that the darker the eye color, the better.

* Emission theory ( vision ), the proposal that visual perception is accomplished by rays of light emitted by the eyes

The many blind people who do entrain to the 24-hour light / dark cycle have eyes with functioning retinas including operative non-visual light-sensitive cells.

Their night vision is especially good due to the presence of a tapetum lucidum, which reflects light back inside the eyeball, and gives felid eyes their distinctive shine.

As a result, the eyes of felids are approximately six times more light sensitive than those of humans, and many species are at least partially nocturnal.

* The incoming radiation from the Sun is mostly in the form of visible light and nearby wavelengths, largely in the range 0. 2 – 4 μm, corresponding to the Sun's radiative temperature of 6, 000 K. Almost half the radiation is in the form of " visible " light, which our eyes are adapted to use.

Nocturnal species have excellent night vision ; their eyes are 350 times more sensitive to light than the human eye.

' The light was within a foot of his eyes.

One likely chain of development is that the eyes originated as simple patches of photoreceptor cells that could detect the presence or absence of light, but not its direction.

It may establish the relation of the figure of the dancer to light and color, in which case changes in the light or color will set off a kaleidescope of visual designs.

The extent to which we can persuade the less developed countries to appraise their own resources, to set targets toward which they should be working, to establish in the light of this forward perspective the most urgent priorities for their immediate attention, and to do the other things which they must do to help themselves, all on a realistic long-term basis, will depend importantly on the incentives we place before them.

During the discharge the magnetic forces set up by the passage of current cause the edges of the foil to roll inward toward its center line, thus allowing light to pass into the camera.

He was perhaps thirty-two, nicely set up, with light brown hair that had a pronounced wave.

* Lit as the past tense of light is more common than lighted in the UK ; American English uses lit to mean " set afire " / " kindled " / " made to emit light " but lighted to mean " cast light upon " ( e. g., " The stagehand lighted the set and then lit a cigarette .").

The first a pastoral opera, L ' amore innocente ( Innocent Love ) was a light hearted comedy set in the Austrian mountains, and the second was based on an episode from Cervantes Don Quixote – Don Chisciotte alle nozze di Gamace ( Don Quixote at the Marriage of Camacho ).

Vases filled with water used to start fires were known in the ancient world, and metaphorical significance was drawn ( by the early Church Fathers, for instance ) from the fact that the water remained cool even though the light passing through it would set materials on fire.

The chessboard is placed with a light square at the right-hand end of the rank nearest to each player, and the pieces are set out as shown in the diagram, with each queen on its own color.

Attention is sometimes seen as a spotlight, meaning one can only shine the light on a particular set of information.

Once the ray either encounters a light source, or more probably once a set limiting number of bounces has been evaluated, then the surface illumination at that final point is evaluated using techniques described above, and the changes along the way through the various bounces evaluated to estimate a value observed at the point of view.

The tour for " Freedom of Choice " featured the band performing in front of large custom light boxes which could be laid on their back to form a second, smaller stage during the second half of the set.

Logical matrix | Logical matrices of the Bell number | 52 equivalence relations on a 5-element set ( Colored fields, including those in light gray, stand for ones ; white fields for zeros.

To get the animation he wanted, the effects crew filmed the miniature model set of New York City they used for other scenes under black light with reflective tape placed along every edge of the model buildings.

For fluids which are sufficiently dense to be a continuum, do not contain ionized species, and have velocities small in relation to the speed of light, the momentum equations for Newtonian fluids are the Navier-Stokes equations, which is a non-linear set of differential equations that describes the flow of a fluid whose stress depends linearly on velocity gradients and pressure.

They are defined by the set of light cones ( see the image on the left ).

The light-cones define a causal structure: for each event A, there is a set of events that can, in principle, either influence or be influenced by A via signals or interactions that do not need to travel faster than light ( such as event B in the image ), and a set of events for which such an influence is impossible ( such as event C in the image ).

A priori, it is not clear whether the new local frames in free fall coincide with the reference frames in which the laws of special relativity hold — that theory is based on the propagation of light, and thus on electromagnetism, which could have a different set of preferred frames.
