Messier 48
Messier 48 or M48, also known as NGC 2548, is an open cluster of stars in the celestial equator, equatorial constellation of Hydra (constellation), Hydra. It sits near Hydra's westernmost limit with Monoceros, about to the east and slightly south of Hydra's brightest star, Alphard. This grouping was discovered by Charles Messier in 1771, but there is no cluster precisely where Messier indicated; he made an error, as he did with M47. The value that he gave for the right ascension matches, however, his declination is off by five degrees. Credit for discovery is sometimes given instead to Caroline Herschel in 1783. Her nephew John Herschel described it as, "a superb cluster which fills the whole field; stars of 9th and 10th to the 13th magnitude – and none below, but the whole ground of the sky on which it stands is singularly dotted over with infinitely minute points". M48 is visible to the naked eye under good atmospheric conditions. The brightest member is the star HIP 403 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mersenne Prime
In mathematics, a Mersenne prime is a prime number that is one less than a power of two. That is, it is a prime number of the form for some integer . They are named after Marin Mersenne, a French Minim friar, who studied them in the early 17th century. If is a composite number then so is . Therefore, an equivalent definition of the Mersenne primes is that they are the prime numbers of the form for some prime . The exponents which give Mersenne primes are 2, 3, 5, 7, 13, 17, 19, 31, ... and the resulting Mersenne primes are 3, 7, 31, 127, 8191, 131071, 524287, 2147483647, ... . Numbers of the form without the primality requirement may be called Mersenne numbers. Sometimes, however, Mersenne numbers are defined to have the additional requirement that be prime. The smallest composite Mersenne number with prime exponent ''n'' is . Mersenne primes were studied in antiquity because of their close connection to perfect numbers: the Euclid–Euler theorem as ...

M48 Patton
The M48 Patton is an American List of main battle tanks by generation#First generation, first-generation main battle tank (MBT) introduced in February 1952, being designated as the 90mm Gun Tank: M48. It was designed as a replacement for the M26 Pershing, M4 Sherman, M46 Patton, M46 and M47 Patton tanks, and was the main battle tank of the U.S. Army and U.S. Marine Corps in the Vietnam War. Nearly 12,000 M48s were built, mainly by Chrysler and American Locomotive Company, from 1952 to 1961. The M48 Patton was the first U.S. medium gun tank with a four man crew, which replaced the traditional 5 crewmen tanks, a centerline driver's compartment, and no bow machine gun. As with nearly all new armored vehicles it had a wide variety of suspension systems, Cupola (military), cupola styles, power packs, fenders and other details among individual tanks. The early designs, up to the M48A2C, were powered by a gasoline engine. The M48A3 and A5 versions used a diesel engine, however, gasol ...

MIM-72 Chaparral
The MIM-72A/M48 Chaparral is an American-made self-propelled surface-to-air missile system based on the AIM-9 Sidewinder air-to-air missile system. The launcher is based on the M113 family of vehicles. It entered service with the United States Army in 1969 and was phased out between 1990 and 1998. It was intended to be used along with the M163 VADS, the Vulcan ADS covering short-range short-time engagements, and the Chaparral for longer range use. Development Mauler Starting in 1959 the U.S. Army MICOM (Missile Command) began development of an ambitious anti-aircraft missile system under their "Forward Area Air Defense" (FAAD) program. Known as the MIM-46 Mauler, it was based on a modified M113 chassis carrying a large rotating A-frame rack on top with nine missiles and both long-range search and shorter-range tracking radars. Operation was to be almost entirely automatic, with the operators simply selecting targets from the search radar's display and then pressing "fire". The ...

M-48 (Michigan Highway)
M-48 is an east–west state trunkline highway in the Upper Peninsula (UP) of the US state of Michigan. It connects Rudyard with Pickford and continues to the far eastern end of the UP. The highway runs for through rural parts of Chippewa County, including along the county line with Mackinac County. Between 580 and 1,800 vehicles a day use the roadway daily. The highway was designated by 1919 along a route that ran much farther west in the UP. Within its first decade, M-48 was extended to end at a point north of Newberry. Since the 1960s, it has had its current configuration. A section of roadway that was previously used as part of the western end of the highway was redesignated as a section H-40 in the 1970s. Route description M-48 currently starts at an interchange with Interstate 75 (I-75) in the Rudyard area. The highway runs west from the interchange into Rudyard where it turns south, running concurrently with county road H-63. M-48 turns eastward south of to ...

M48 Motorway
The M48 is a long motorway in Great Britain, which crosses the Severn near Chepstow, Monmouthshire, linking England with Wales via the Severn Bridge. This road used to be the M4, and as a result is anomalously numbered: as it lies to the north of the M4 and to the west of the M5, it is in the Motorway Zone 5. The M4, the M48 and the A48(M) motorway are the only motorways in Wales. Route Travelling from east to west, after leaving the M4 at Awkley, junction 21, near Olveston in England, the M48 begins by heading north-west towards Aust, junction 1. It crosses the Severn and Wye rivers. Entering Wales, the M48 heads south-west after junction 2, passing to the south of Chepstow, past Crick and continuing in a south-westerly direction, passing Caldicot and Rogiet. The motorway rejoins the M4 at Undy, junction 23 to the east of Magor. Junction 2 can be reached via the A466, which leads to the A48. The junction gives access to the Wye Valley, an Area of Outstanding Natural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M48 (Cape Town)
The City of Cape Town (Cape Town metropolitan area) like most South African metropolitan areas, uses Metropolitan or "M" routes for important intra-city routes, a layer below National (N) roads and Regional (R) roads.

M48 Mauser
The Zastava M48 (Serbo-Croatian: ''Puška M.48 7,9 mm'' / Пушка M.48 7,9 mm, "Rifle M.48 7.9 mm") is a post World War II Yugoslav version of the German Karabiner 98k designed by Mauser and the Belgian designed M24 series. It was the standard service rifle of the Yugoslav People's Army from the early 1950s until its replacement by the Zastava M59/66, a licensed copy of the Soviet SKS semiautomatic carbine, in the early 1960s. History After World War II, Yugoslavia took the design of the 98k rifle series and produced its own domestic variant with minor modifications. Although very similar in external appearance, many of the parts of the Yugoslav and German rifles are not interchangeable, especially the bolt and related action parts. M48s are usually distinguished from the 98k by the top handguard, which extends behind the rear sight and ends just in front of the receiver ring, although this feature exists on other models as well. The M48 was designed with a stock simila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
76 Mm Mountain Gun M48
The 76 mm mountain gun M-48 (AKA the Tito Gun), was developed after the Second World War to meet the requirements of Yugoslav People's Army mountain units, it can also be used as a field gun. Description The first M-48B-1 models may have been Czech M28 mountain guns (bought by Yugoslavia in 1930s) relined from original 75mm calibre to Soviet 76mm (as used on their 76mm regimental and divisional guns), with muzzle-brake added to cope with increased recoil (also Skoda type, borrowed from M.36 AA model). There have been at least five variants of the M48: * The M-48 (B-1) has pneumatic tyres and a maximum towing speed of 60 km/h. It can also be towed by animals in tandem or disassembled into eight pack loads. * The M-48 (B-1A1-I) has the pneumatic tyres and wheels as fitted to the M48 (B-1), plus some of the features of the suspension of the M48 (B-1A2). * The M-48 (B-1A2) can also be used as a field piece but cannot be towed by animals or disassembled for pack transport. * ...
