Screen in computing is an input device allowing the user to communicate
with the computer by touching a display screen with a finger. In this
way, the user can point to a required menu option or item of data. Touch
screens are used less widely than other pointing devices such as the
mouse or joystick.
Typically, the screen is able to detect the
touch either because the finger presses against a sensitive membrane or
because it interrupts a gird of light beams crossing the screen surface.
Universal Time (UT)
Time is another name for Greenwich Mean Time. It is based on the
rotation Of the Earth, which is not quite constant. Since 1972, UT has
been replaced by Co-Ordinate Universal Time (UTC),which
is based on uniform atomic time. The ocean as well as the land. The
virgin Islands in the Caribbean and the Hawaiian Islands are nothing
more than the projecting tips of gigantic submarine peaks. In fact The
Hawaiian mountain Mauna Kea, a large portion of which is undersea, has a
full height Of 33476 feet which, when measured from the ocean floor,
makes it more than 4,000 Feet taller than Mt. Everest. Though mountains
seem to be randomly scattered Throughout the planet, most major ranges
are situated within two relatively narrow strips That run like jagged
bands around the Earth. The first extends across the Pacific, up the
West Coast of South and North America, into Asia, down through New
Zealand, and into Antarctica. The Second extends across North Africa,
Southern Europe, Asia Minor and into Asia.
countdown clock that measures about 3.33 (w) 3.73 (H) 3.33 (D) allows
us to count days, hours, minutes and seconds until important dates such
as birthdays, weddings etc. We can load the clock up with our load the
clock up with our own important dates. The control buttons allow us to
go through them quickly and select the ones we want. We can even
programme it to display custom messages. It to display custom messages.

is a state of inactivity and reduced metabolic activity, similar to
hibernation. It occurs during the dry season in species such as lungfish
and snails. In Botany, the term is used to describe the way in which
flower petals and sepals are folded in the buds.
is ridge formed by wind erosion from a dried-up riverbed or similar
feature, as in Chad, China, Peru and North America. On the planet Mars
Yardangs occur on a massive scale.
birds are found in South American caves. To find their way about in the
dark, they emit rapid clicks, which send back echoes, telling them of
anything in their path.
mirrors have been made in China and Japan for centuries. When you look
into one of these highly polished bronze mirrors you see, as you might
expect, your reflection – and nothing more. However, if you hold the
mirror towards the Sun and reflect the light on to a white surface, the
reflection shows a design, such as a picture of the Buddha. Over the
years, the making of magic mirrors has remained a closely guarded secret
and even today few people know exactly how they work.
Canal is North African civil-engineering project to divert the White
Nile in order to improve the water supply to Egypt from Sudan. The
project was conceived in the 1940s but was not begun until 1982, and
work was halted by the outbreak of civil war in Sudan in 1983.
Why don’t we sneeze while sleeping?
is nothing but a forceful expulsion of air through the windpipe in our
neck. This sudden and forceful expulsion of air is caused by a sudden
contraction of the muscles around the lungs and the diaphragm, the
muscular membrane below the lungs. This forces out more air from lungs
than is normally breathed out. This sudden action of muscles and
diaphragm is caused by the irritation of the nerves of the nostril by
dust, smoke, pollen etc. or microorganisms like cold virus. However,
during sleep these nerves remain less alert and the muscles relaxed.
Therefore, the air in the lungs cannot be forced out suddenly as the
muscles take some time to contract and so we don’t sneeze.
Why does an aeroplane taxi before taking off?
before taking off helps an aeroplane in two ways. Firstly this helps
aeroplane in attaining a minimum initial speed which is required before
leaving the ground and secondly it helps to create a difference in
pressure on the wing surfaces. The shape of the wings of aeroplane is so
designed that the curvature of their upper surface is more than that of
the lower surface and the front end is round while the inner end is
flat. When the plane runs, it speeds up the air current flowing above
and below the wing. However, the wind has to travel more distance on
upper surface than on the lower one. Consequently the velocity of air
also is more at the upper surface than at the lower surface. According
to Bernoulli’s law the pressure generated by the moveing air on the
upper surface is less than acting on the lower surface. Due to its
pressure difference, a thrust, equal to this difference act on the wing
and it starts rising up.
Why are railway tracks covered with ballasts?
rail track is the very basis of the rail road line. It consists of
parallel rails laid on cross-ties on a roadbed of ballast. The standard
steel rail is shaped like the letter ‘T’, resting on a wide base or
flange. It is fastened at right angles to wooden or concrete sections
called cross-ties, which are embedded in crushed stone or cinders,
ballast, to hold them steady. The ballast also covers part of the rails.
When train passes over the track the pressure acting on it changes
continuously. The variation in pressure is so much that if, instead of
ballast. A rigid road like material is used, it would crack. The ballast
gives the track flexibility to face this variable pressure. In addition
to this cushioning effect, the ballast also helps drainage.
Why is there a lull before a storm?
are very strong winds that temporarily interrupt the more general air
movements prevailing at a time over a place. When a storm approaches a
place, it changes the direction of the wind already blowing in that
area. As the wind changes direction suddenly and before stormy winds
begin to blow from the other side there is a short period when there is
no wind in that area. This is known as the lull.
