Since the Universe has a finite age, and light travels at a finite speed, there may be events in the past whose light has not had time to reach us.

Since oxygenated and deoxygenated blood reflects light by different amounts, we can study which areas are more active ( i. e., those that have more oxygenated blood ).

Since light is an oscillation it is not affected by travelling through static electric or magnetic fields in a linear medium such as a vacuum.

Since the visible spectrum of light is composed of wavelengths between 390 and 750 nanometers ( nm ), if the droplet sizes in the emulsion are below about 100 nm, the light can penetrate through the emulsion without being scattered.

Since this implies that one particle is communicating with the other instantaneously across space, i. e. faster than light, this is the " paradox ".

Since frequency and wavelength are inversely proportional, this is equivalent to saying that the frequency of the light is reduced towards the red part of the light spectrum, giving this phenomenon the name redshift.

Since EtBr stained DNA is not visible in natural light, scientists mix DNA with negatively charged loading buffers before adding the mixture to the gel.

Since the 1980s, various experiments have verified that it is possible for the group velocity of laser light pulses sent through specially prepared materials to significantly exceed the speed of light in vacuum.

Since absorption is cumulative, the color effect intensifies with increasing thickness or if internal reflections cause the light to take a longer path through the ice.

Since Brighid represented the light half of the year, and the power that will bring people from the dark season of winter into spring, her presence was very important at this time of year.

Since the early 1980s, a global dark-sky movement has emerged, with concerned people campaigning to reduce the amount of light pollution.

Since not everyone is irritated by the same lighting sources, it is common for one person's light " pollution " to be light that is desirable for another.

Since relativity postulates that the speed of light is the same for all observers, the Lorentz transformation must preserve the spacetime interval between any two events in Minkowski space.

Since the early 1990s, a light has been fixed to it about one-third of the way up.

Since 1983, it has been defined as " the length of the path travelled by light in vacuum during a time interval of of a second.

Since fluorescence emission differs in wavelength ( color ) from the excitation light, an ideal fluorescent image shows only the structure of interest that was labeled with the fluorescent dye.

Since any fluorescence image is made up of a large number of such small fluorescent light sources, the image is said to be " convolved by the point spread function ".

Since he was the light of the world, where was this light, they asked, when he was in the womb of the Virgin?

Since Rhode Island at that time did not have such sanction, his opinion was not popular.

Since the great flood of these dystopias has appeared only in the last twelve years, it seems fairly reasonable to assume that the chief impetus was the 1949 publication of Nineteen Eighty-Four, an assumption which is supported by the frequent echoes of such details as Room 101, along with education by conditioning from Brave New World, a book to which science-fiction writers may well have returned with new interest after reading the more powerful Orwell dystopia.

Those famous lines of the Greek Anthology with which a fading beauty dedicates her mirror at the shrine of a goddess reveal a wise attitude: `` Venus, take my votive glass, Since I am not what I was, What from this day I shall be, Venus, let me never see ''.

Since it was issued in the spring of 1611, the King James Version has been most generally considered the most poetic and beautiful of all translations of the Bible.

Since she could not act, one part suited her as well as any other, and so she was the first person to offer Mr. Lincoln a glass of water, holding it up to the box, high above her head, to Miss Harris, who had asked for it.

Since ordinary breakfast-table conversation was impossible, it was at least something that they were able to offer Eugene the sugar bowl with their sugar in it, and the plate of bread and butter, and that Eugene could return the pitcher of hot milk to them handle first.

Since his Christ was to be life size, how was Mary to hold him on her lap without the relationship seeming ungainly??

Since the writer had established this democratic procedure in the beginning he had to go along with their decision -- after, of course, pointing out whether he thought their decision was a wise or an unwise one.

Since this type of item was not in the statute when section 381 was enacted in 1954, one cannot say with certainty what effect the enactment of that section should have.

Since writing was practiced in the Aegean before the end of the century, we may hope that the details of tradition will now be occasionally useful.

Since the strength of the Mexicans had been underrated, too small a posse had been collected, and since the deputy had not been provided with search warrants, MacPherson and his men decided it was much wiser to withdraw.

Since experience indicates that effluents from oxidation ponds do not create major problems at these BOD concentrations, the goal for the effluent quality of the accelerated treatment system was the same as from conventional oxidation ponds.

Since the psychiatric interview, like any other interview, depends on communication, it is significant to note that the therapist in this interview was a man of marked skill and long experience.

Since Fogg's was a one-man, one-plane flying service, this meant that he would have to do both trips, flying alone 600 miles a day, under sub-freezing temperature conditions.

Since the 1946 disaster there have been 15 tsunami in the Pacific, but only one was of any consequence.
