  Mars Global Surveyor Science Sampler Data Set Collection (VOLINFO)
The science observations were acquired during the descending leg of each orbit; that is, as the spacecraft moved from north to south.
Science objectives of radio science investigations include measurement of small perturbations in spacecraft velocity from Doppler shifts on transmitted signals, followed by inference of detailed gravitational fields from solutions of systems of simultaneous equations based on such measurements.
Many images on the MGS Science Sampler volume are more than 4,000 rows (lines) and it was thought that increasing the size of the images would potentially make it more difficult for investigators to display and use the images.

Perhaps the most intriguing is that the effective noise strength (or temperature) is internally generated and dependent on the state of the system, rather than imposed by an external temperature bath.
The authors suggest their results establish a causal relationship between telomere shortening and in vitro cellular replicative senescence, and that the ability to maintain normal human cells in a youthful state can have important applications in research and medicine.
They are essential for normal chromosome replication, and since their length shortens a bit with each replication, they are believed to be involved in the aging of the cell.

 ESA - Space Science - Astrology to astronomy: Jean-Dominique Cassini   (Site not responding. Last check: 2007-08-17)
Because of his interest in astrology and science, he was employed by a rich amateur astronomer, Marquis Cornelio Malvasia, in Bologna.
In 1668 Cassini compiled tables showing the positions of Jupiter’s satellites and this was used by the Danish astronomer Ole Rømer to establish that the speed of light is finite.
In 1671, Cassini held the directorship to the Observatoire de Paris and two years later became a French citizen, changing his name to Jean-Dominique.

 The Huygens Probe: Science, Payload and Mission Overview   (Site not responding. Last check: 2007-08-17)
Not only is it a crucial manoeuvre, but also a period of unique Orbiter science activity as, at that time, the spacecraft is as close as it ever will be to the planet (at 0.3 RS about 2 h before and 2 h after ring-plane crossing).
However, for maximising the science return, the measurement cycle during the last part of the descent is based on the true altitude.
The Huygens Science Working Team (HSWT) intends to produce a commonly agreed descent profile within weeks of the event to allow all experimenters to analyse their data and interpret their measurements in the most efficient way.

 Department of Computer Science
Students may select computer science as their major in the second (sophomore) year and complete the computer science major and mathematics minor requirements in the remaining three years with little difficulty.
It might be possible to complete the major and minor requirements in two years provided the student has completed all other degree requirements (including the non-mathematics minor) in the first two years and is prepared to take a heavy load of computer science and mathematics courses in the final years.
Note: Only two COMP electives are needed in senior year, but often a sequence starts in the fall, so it may be necessary to take the two classes during the fall and winter quarters.

 Moon - Encyclopedia, History, Geography and Biography
While some of the Moon's magnetism is thought to be intrinsic (such as a strip of the lunar crust called the Rima Sirsalis), collision with other celestial bodies might have imparted some of the Moon's magnetic properties.
Indeed, a long-standing question in planetary science is whether an airless solar system body, such as the Moon, can obtain magnetism from impact processes such as comets and asteroids.
Magnetic measurements can also supply information about the size and electrical conductivity of the lunar core — evidence that will help scientists better understand the Moon's origins.

Increased expertise is reflected in many ways, but especially in more effective and efficient diagnosis and in the more thoughtful identification and compassionate use of individual patients' predicaments, rights, and preferences in making clinical decisi ons about their care.
By best available external clinical evidence we mean clinically relevant research, often from the basic sciences of medicine, but especially from patient centred clinical research into the accuracy and precision of diagnostic tests (including the clinical examination), the power of prognostic markers, and the efficacy and safety of therapeutic, rehabilitative, and preventive regimens.
For a question about prognosis, we need proper follow-up studies of patients assembled at a uniform, early point in the clinical course of their disease.

 It takes more than one kind of telescope to see the light
By using a curved mirror to reflect and focus the light inside the tube, he was able to reduce the length of the telescope dramatically.
Such serendipitous events as the GRO storage tape failure often reveal new ways of looking at old science, causing scientists to rethink ideas previously taken for granted.
Although Phillips says an all-wave telescope is not currently a topic of serious discussion in the scientific community, satellites with coordinated telescopes have worked well in the past.

His chief works argue that a society dedicated to science and technology would "relieve the human estate," providing a longer, healthier, more informed, and more ennobling life for everyone.
In the conversation of his characters he allows readers to see the reasons for kindling spiritual warfare against the spiritual rulers of European civilization.
Bacon's reputation as a philosopher of science has sunk since the 17th and early 18th centuries, when he was accorded the title 'Father of Experimental Philosophy.' It is high time for this illustrious designation to be restored to him.
