  Millisecond pulsar - Wikipedia, the free encyclopedia
A millisecond pulsar (MSP), often referred to as "recycled pulsar", is a pulsar with a rotational period in the range of about 1-10 milliseconds.
Many millisecond pulsars are found in globular clusters because the extremely high stellar density of these systems leads to exchange interactions that create the kind of mass-transfer binaries that spin pulsars up to millisecond pulsars.
The first millisecond pulsar, PSR B1937+21, was discovered in 1982 by Backer et al.

 Millisecond response the 'spec du jour' - Boston.com
The industry norm dropped from 25 milliseconds three years ago to about 8 milliseconds for LCD computer monitors and 16 milliseconds for LCD TVs by the end of 2005.
These are blistering fast times: a millisecond is one-thousandths of a second, and an eye blink is estimated to last 100 milliseconds to 150 milliseconds.
The slim differences, say between 6 milliseconds and 2 milliseconds, may not affect the average computer user, but it might for avid gamers, who usually embrace cutting-edge products and might be more inclined to notice a little blurring while gripped in an action sequence.

With the CRAY C90, Taylor's group can sift the data they collect at Arecibo with far greater sensitivity and efficiency than was possible 20 years ago, and this computing power is yielding a significant payoff in the discovery of pulsars.
Although that had a period of 59 milliseconds, it was the first of the genre.
Only about 50 millisecond pulsars are known, and 30 of these are in distant globular star clusters, where other stars' gravitational fields can interfere with precision measurements of the pulsar.

 ESA Portal - First view of a newborn millisecond pulsar?
A series of observations of the millisecond pulsar PSR J1740-5340 (spinning at 274 times per second) and its companion star from the ESA/NASA Hubble Space Telescope and the Parkes radio telescope seem to show the final stage of the pulsar acceleration process for the first time.
The observations show that the millisecond pulsar's companion is not the expected white dwarf, but a bloated red star, whose radius is about 100 times greater than that of a white dwarf and at least five times greater than a normal star of similar mass!
A system consisting of a millisecond pulsar and a star that is not a white dwarf has never been seen before.

A pulsar is a rapidly rotating highly magnetized neutron star, formed in the supernova explosion of a massive star.
It is believed that future millisecond pulsars enter the "graveyard" as members of binary systems.
Once "spun-up", the pulsar is "born again" as a millisecond pulsar.

 Computer storage - Wikipedia, the free encyclopedia
The time taken to access a given byte of information stored on a hard disk is typically a few thousandths of a second, or milliseconds.
By contrast, the time taken to access a given byte of information stored in random access memory is measured in thousand-millionths of a second, or nanoseconds.
The relevant unit of measurement is typically nanosecond for primary storage, millisecond for secondary storage, and second for tertiary storage.

 Universe Today - How Millisecond Pulsars Spin So Fast
This large sample is a bonanza for astronomers seeking to test theories for the origin of millisecond pulsars, and increases the chances that they will find a critical transitional object such 47 Tuc W. 47 Tuc W stands out from the crowd because it produces more high-energy X-rays than the others.
Most astronomers accept the binary spin-up scenario for creating millisecond pulsars because they have observed neutron stars speeding up in X-ray binary systems, and almost all radio millisecond pulsars are observed to be in binary systems.
It links a millisecond pulsar with many of the properties of an X-ray binary, to J1808, an X-ray binary that behaves in many ways like a millisecond pulsar, thus providing a strong chain of evidence to support the theory.

 Millisecond X-Ray Pulsars
     Millisecond radio pulsars (MRPs) are thought to be old neutron stars recycled to rapid rotation by accretion in LMXRBs (see Bhattacharya 1995, and references therein).
The millisecond rotation period of the neutron stars in five LMXRBs (4U 1728-34, 4U 1636-53, KS 1731-26, X1743-29, and Aql X-1) is seen directly as a near coherent X-ray pulsation during X-ray bursts (Strohmayer et al.
The pulsation amplitude of the millisecond pulsations during the burst is 5%

 Polarimetry of Millisecond Pulsars   (Site not responding. Last check: 2007-11-07)
Millisecond pulsars have much shorter spin periods (\sim ms vs. \sim s), and weaker magnetic fields (B 10^8 G vs. \sim 10^12 G) than their slower counterparts.
The characteristics of their emission regions may therefore be different from those of slow pulsars, and polarimetry is probably the best diagnostic for investigating this possibility.
In addition, polarimetry data were obtained for two millisecond pulsars at the Effelsberg telescope in Germany, at 1400 MHz, using the new EBPP (Effelsberg--Berkeley--Pulsar--Processor).

 2.4 Normal and millisecond pulsars   (Site not responding. Last check: 2007-11-07)
Another relatively poorly understood area is the existence of solitary millisecond pulsars in the Galactic disk (which comprise just under 20% of all Galactic millisecond pulsars).
Although it has been proposed that the millisecond pulsars have got rid of their companion by ablation, as appears to be happening in the PSR B1957+20 system [83
The main reason for this difference surely lies in the fact that about 80% of the millisecond pulsars are members of binary systems (§ 2.4) which could not have survived had the neutron star received a substantial kick velocity.

 The Human is a Digital Mechanism.
The shape of the pulse with time is incidental, it is the presence or absence of the pulse which matters in the data transmission.
The propagation rate is about 1 millisecond per computation (the time required for the pulse to reach its peak, travel a short distance, and fire the next stage).
For example, if the average number of terminal branches was 20, and the computation extended to a period allowing 10 stages of calculation (about 10 milliseconds), the signal from a single axon could reach far more than all of the cells in the brain.

 Millisecond Pulsar Animation
For about 20 years astrophysicists have suspected that the most rapidly spinning neutron stars known, the millisecond radio pulsars, achieved their dizzying millisecond spin periods over a billion year accretion phase during which material is transferred to the neutron star from a binary companion.
This transfer of material, which occurs via an accretion disk orbiting the neutron star, produces a torque on the neutron star that causes it slowly to spin faster and faster.
All that remains at the end is a highly compact, rapidly rotating neutron star which produces a pair of radio beams and may be observable as a millisecond radio pulsar.

 The Daily WTF - The Millisecond Converter
Given the problem of converting milliseconds to minutes, I imagine that most of us would simply divide the number of milliseconds by 60,000.
But any system that measures and stores enough milliseconds to make subtractable minute values is borked up enough as it is. At that point you might as well meaure fractional minutes (5.25 minutes = 5 minutes, 15 seconds).
He needs to divide the milliseconds by 2 then multiply the resulting minutes by 2.

 Astronomers weigh 'recycled' millisecond pulsar
This pulsar spins every 2.9 milliseconds, or 340 times per second; the pulsar and its white dwarf companion star orbit their common center of gravity every 1.5 days.
If this mass is typical, we can infer that a millisecond pulsar can be produced with the accretion of less than 0.2 solar masses from its companion.
If this is the case, then the pulsar recycling process must be messy: more than half a solar mass must have been lost from the companion as a wind of ejected gas as it evolved from a normal main sequence star to a white dwarf.

In fact, a 16-millisecond response time translates roughly to 60 frames per second - the rate of fluid, full-motion video - and thus theoretically eliminates obvious blurring.
Blurring from motion in video is an inherent drawback of LCD displays - an effect that doesn't exist for plasma panels or traditional CRTs.
Note that other key features - contrast ratio, resolution, brightness, and cable inputs - are today generally more important to the quality and price of an LCD display than millisecond response times.
