 A Deepness in the Sky - Wikipedia, the free encyclopedia
Time-measurement details provide an interesting concept in the book: the Qeng Ho measure time primarily in terms of seconds, since the notion of days, months, and years has no usefulness between various star systems.
The timekeeping system, based on the Unix epoch, uses terms such as kiloseconds and megaseconds.
Only one concrete connection links A Deepness in the Sky with A Fire Upon the Deep: the character of Pham Nuwen, the "Programmer-at-Arms", who appears in both books.

 Decimal Time - Metric Time
Metric multiples include the kilosecond and megasecond, but for everyday use, non-metric minutes, hours, and days are used, instead, and larger units such as weeks, months, and years.
Since the mean solar day and tropical year both vary slightly, the SI second was defined more precisely in 1967 as 9,192,631,770 cycles of the vibration of the cesium 133 atom.
For this reason, critics claim that truly metric time does not exist, and since the second is not a decimal fraction of the day, it also cannot be used as the basis of a decimal time of day.

 Photocontrol of Cation Complexation with a Benzothiazolium Styryl Azacrown Ether Dye: Spectroscopic Studies on ...   (Site not responding. Last check: 2007-11-02)
UV-visible absorption and emission spectroscopy have been used to study the complexation of Ba with a benzothiazolium styryl azacrown ether dye and two derivatives, one without an azacrown and one with an alkylsulfonate pendant to the benzothiazolium group.
Studies of the thermal cis-trans isomerization on the kilosecond time scale, and of the excited state leading to trans-cis photoisomerization on the picosecond time scale, are reported which enable a quantitative analysis of the kinetics and complexation equilibria to be obtained.
An overall mechanism is proposed for the thermal and photochemical reactions of this dye which indicates that it is a good candidate for applications which require the photocontrolled complexation/release of barium cations in solution.

A day is 86.4 kiloseconds long, plus or minus an extra leap second every so often.
A kilosecond is between 15 and 20 minutes long (16.667 more precisely).
It would not be hard to structure our day around time periods of 1 kilosecond IF WE WANTED TO.

Partial covering of the central emission source by the out-flowing gas plays a critical role in UV line formation, and may be important in the X-ray absorber.
We have studied the best X-ray data set of an AGN outflow, the Chandra 900 kilosecond observation of NGC 3783, for the effects of covering factor in the strongly saturated line series of Ne X and O VII.
Due to the limited resolution and signal to noise around 1 keV, it is difficult to determine a correct model for absorption line formation.

 Magnetically-Controlled Circumstellar Environments of Hot Stars   (Site not responding. Last check: 2007-11-02)
As a preliminary test of this Centrifugal Breakout mechanism for X-ray flare generation, we have conducted 2D MHD simulations for a rapidly-rotating star at moderate magnetic confinement.
Below, we show the time evolution of the plasma density, temperature and speed, over a 100 kilosecond run starting 400 kiloseconds after our initial condition.
The stretching and snapping of magnetic field lines, as a result of centrifugal breakout, can clearly be seen in these animations; note in particular the heating to temperatures in excess of 100 million Kelvin, arising from the energy released during magnetic reconnection.

In addition, the excellent angular resolution capabilities of Chandra have proved very useful in clearly identifying counterparts at different wavelengths (such as optical and radio) for these detected X-ray sources.
We present the results of a 50 kilosecond Chandra observation of the nearby Sculptor Group Sd galaxy NGC 7793: we have observed this galaxy as part of a multi-wavelength campaign to search for supernova remnants in nearby galaxies.
Properties of the discrete X-ray sources detected in this galaxy will be presented: we will also describe our search for optical and radio counterparts to the detected X-ray sources.

 SBF Glossary: S
We're going to take it as exactly 8 for purposes of explanation.) Assuming (it's a fairly accurate assumption) that air behaves as an ideal gas, then under maximum pressure the gas is compressed to one ninth of its atmospheric-pressure volume.
The pressurization is usually applied for about 4 to 8 minutes (that would be about one quarter to one half of a kilosecond, for all you good people who don't understand stuff that isn't in metric units).
If this is enough time for mechanical equilibrium to be achieved, then water (incompressible to a good approximation) has filled 8/9 of the initial air volume in the shell.
