Dearth of teachers :
Many schools operate with only one teacher
dearth of teachers is hampering the education process and the Ministry
of Education is looking at ways to bring redress to students affected by
the lack of teachers and facilities in their schools.
According to Education Ministry sources records show that there are
about ninety schools throughout the country with only a single teacher
while 168 schools had to make do with just two teachers. In the nothern
Province alone there were fifty eight schools with one teacher.
Three such schools also exist in the western province,nine in the
Central Province,one in the Southern Province,nine in the Eastern
province province,two in the North western Province,three in the North
Central, two in the Uva province and five in the Sabaragamuwa Province.
Meanwhile, it has also been found that 48 schools in the North are
managed with only two teachers.Twenty-nine such schools also exist in
the Central Province.
In addition,according to the statistics released by the Ministry's
Planning Division,254 schools operate with only three teachers,while 375
schools operate with only four teachers.
Statistics show that out of the 9,790 schools presently functioning
in the country,1,552 schools have fewer than 50 students each.
Additionally,it was revealed that only 187 schools have a student
population of more than 2,500.
Milky Way's black hole devours asteroids
of you who keep track of the latest developments in astronomy may be
aware of the existence of a giant black hole in the centre of our Milky
Way. For several years X ray flares from the black hole which has been
named as Sagitarius A* or Sgr A* for short, have been detected once a
day by the the Chandra X ray Observatory which is part of NASA's fleet
of "great observatories. According to latest observations the frequent
flares could be due to the giant black hole vaporizing and devouring
Astronomers using data from NASA's Chandra X-ray Observatory say that
even though there were doubts as to whether asteroids could form at all
in the harsh environments found near a supermassive black hole, studies
of the recent data from Chandra suggest otherwise.
"It's exciting because our study suggests that a huge number of them
are needed to produce these flares, " says Kastytis Zubovas of the
University of Leicester in the United Kingdom, and lead author of the
report appearing in the Monthly Notices of the Royal Astronomical
Zubovas and his colleagues suggest there is a cloud around Sgr A*
containing trillions of asteroids and comets, stripped from their parent
stars. Asteroids passing within about 100 million miles of the black
hole, roughly the distance between Earth and the sun, would be torn into
pieces by the tidal forces from the black hole.
These fragments then would be vaporized by friction as they pass
through the hot, thin gas flowing onto Sgr A*, similar to a meteor
heating up and glowing as it falls through Earth's atmosphere. A flare
is produced and the remains of the asteroid are swallowed eventually by
the black hole.
"An asteroid's orbit can change if it ventures too close to a star or
planet near Sgr A*," said co-author Sergei Nayakshin, also of the
University of Leicester. "If it's thrown toward the black hole, it's
doomed." The authors estimate that it would take asteroids larger than
about six miles in radius to generate the flares observed by Chandra.
Meanwhile, Sgr A* also may be consuming smaller asteroids, but these
would be difficult to spot because the flares they generate would be
Very long observations of Sgr A* will be made with Chandra later in
2012 that will give valuable new information about the frequency and
brightness of flares. -Science Daily
