SCIENCE

1. Geo stationary satellites

A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately

35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction

the earth rotates (west to east). At this altitude, one orbit takes 24 hours, the same length of time

as the earth requires to rotate once on its axis. The term geostationary comes from the fact that

such a satellite appears nearly stationary in the sky as seen by a ground-based observer. BGAN,

the new global mobile communications network, uses geostationary satellites.

On June 19, 1981 India launched its first geostationary satellite called APPLE. It was an

experimental communication satellite launched by the Indian Space Research Organisation

(ISRO) with a C-band transponder .

2. Frictional electricity

Frictional electricity is another name for triboelectricity - electricity generated by friction. It's

most commonly associated with static electricity. Charge separation often occurs through rolling

or sliding contact or collision, usually between different materials.2018, By rubbing (friction)

you can create charges which are responsible for generating electricity. ... Friction

produces static electricity by initiating the transfer of electrons between two or more objects.

With regards to electron transfers, objects are either conductors or insulators.,F rictional

Electricity is the electricity produced by rubbing two suitable bodies and transfer of electrons

from one body to other. Historically, this phenomenon was discovered by a greek ' Thales of

Miletus' around 600BC. The name electricity was taken from the Greek word 'Elecktron

3. Oscars of science awarded to Event Horizon Telescope Team

The Event Horizon Telescope Team consists of 347 scientists produced the world first image of

a black hole. They were felicitated with breakthrough Prize in Fundamental Physics. The prize is

known as the Oscars of science with prize money $3 million. The team published the image of

black hole circled by a flame-orange halo of white-hot plasma on the Messier 87 (M87) galaxy.

Directed by Shep Doelman at the Harvard-Smithsonian Center for Astrophysics, the team spent

over a decade simulating an Earth-sized computational telescope that combined the signals

received by eight radio telescopes working in pairs around the world with their sights trained on

the Messier 87 (M87) galaxy, 55 million light-years away. Through this technique, they were

able to achieve an unprecedented resolution and observe the black hole's silhouette for the first

time in history, confirming theoretical predictions about these celestial objects. The event

horizon of a black hole is the point at which its gravitational effects are strong that light cannot

escape its pull. The Breakthrough Prize was launched by Silicon Valley entrepreneurs to

recognize and reward the world's top scientists. They will be recognized at a gala awards

ceremony on November 3, at NASA Ames Research Center in Mountain View, California.

4. Yutu-2 found gel like substance on far side of moon

China's lunar rover Yutu-2 has found a strange gel-like substance during its exploration activities

on the far side of the moon. Gel-like substance: The gel's shape and color are significantly

different from the surrounding lunar soil. The colour of the material has been described as

unusual. The material is located on the inner edge of the impact crater. The substance was found

during the 8th day of an exploration mission to a region covered in small impact craters. Chang-

e-4 lander: The Chang-e-4 Lander and Yutu-2 rover landed on the other side of the moon in

January. It became the first spacecraft to reach the unexplored region of Earth's only satellite.

Scientists believe that the far side of the moon has unique features never before explored on site.

Chang-e 4 is a robotic spacecraft mission. It is part of the second phase of the Chinese Lunar

Exploration Program.

5. Esa and nasa partners for asteroid deflection

The European space agency (ESA) has announced its plan to partner with the National

Aeronautics and Space Administration (NASA) to stop asteroids hitting Earth. The teams from

both the space agencies will meet in Rome in the month of September. The teams will discuss to

deflect the potentially threatening asteroids away from colliding with the planet. In the meet,

Asteroid researchers and spacecraft engineers are to propose the Asteroid Impact Deflection

Assessment (AIDA) which is a viable method of planetary defense. According to the ambitious

technique, one spacecraft will be sent to hit an asteroid and another will be sent out to obverse

and gather data from the crash site. Collision Mission: The asteroid researchers aim for the

smaller body of the double Didymos asteroids between Earth and Mars. For this purpose, NASA

is building the Double Asteroid Impact Test, or Dart spacecraft, which has been scheduled to

launch in 2021. DART will reach its target at 6.6 km/s in September 2022. DART will be

accompanied by an Italian-made miniature CubeSat called LICIACube. This will travel

alongside to capture the moment of impact. On the other hand, ESA's HERA will perform a

Page 11: CONTENTS Science ...nirmalamatha.edu.in/admin/download/58_5124.pdf · A space museum named Dr. APJ Abdul kalam 11. Hyderabad air port launches Face Recognition system for entry on

11

detailed measurement of the asteroid's size and the crater shape. By this study, the researchers

can figure out whether the technique can be used against a real threat. The mission has been

planned to be launched in October 2019

6. Nasas Dragon Fly Mission

NASA has announced that our next destination in the solar system is the unique, richly organic

world Titan. Advancing our search for the building blocks of life, the Dragonfly mission will fly

multiple sorties to sample and examine sites around Saturn’s icy moon.

Dragonfly will launch in 2026 and arrive in 2034. The rotorcraft will fly to dozens of promising

locations on Titan looking for prebiotic chemical processes common on both Titan and Earth.

Dragonfly marks the first time NASA will fly a multi-rotor vehicle for science on another planet;

it has eight rotors and flies like a large drone. It will take advantage of Titan’s dense atmosphere

– four times denser than Earth’s – to become the first vehicle ever to fly its entire science

payload to new places for repeatable and targeted access to surface materials.

Titan is an analog to the very early Earth, and can provide clues to how life may have arisen on

our planet. During its 2.7-year baseline mission, Dragonfly will explore diverse environments

from organic dunes to the floor of an impact crater where liquid water and complex organic

materials key to life once existed together for possibly tens of thousands of years. Its instruments

will study how far pre biotic chemistry may have progressed. They also will investigate the

moon’s atmospheric and surface properties and its subsurface ocean and liquid reservoirs.

Additionally, instruments will search for chemical evidence of past or extant life.

“With the Dragonfly mission, NASA will once again do what no one else can do,” said NASA

Administrator Jim Bridenstine. “Visiting this mysterious ocean world could revolutionize what

we know about life in the universe. This cutting-edge mission would have been unthinkable even

just a few years ago, but we’re now ready for Dragonfly’s amazing flight.”

7. Smart skin

A chameleon can alter the color of its skin so it either blends into the background to hide or

stands out to defend its territory and attract a mate. The chameleon makes these trick look easy,

using photonic crystals in its skin. Scientists, however, have struggled to make a photonic crystal

"smart skin" that changes color in response to the environment, without also changing in size.

ENGLISH

What is the meaning and origin of ‘waiting in the wings’?

During the course of an IPL match, we sometimes hear experts say that a team has several

talented youngsters ‘waiting in the wings’. What they mean by this is should any of the

senior players fail to perform, there are people on the team who can easily replace them. The

uncapped talented youngsters are waiting for their chance to show how good they are.

Chances are, they will get an opportunity to play in the near future.

There are several people waiting in the wings to take over as President.

The players waiting in the wings look forward to the daily practice sessions.

What is the meaning of ‘deuce’ in tennis?

You have probably been watching the French Open on TV! The scoring system in tennis

makes use of some unusual terms — two of them being, ‘love’ and ‘deuce’. A tennis match

usually begins after the umpire has said ‘love all’. By this, he does not mean that he wants

the two players to like or love each other. In this case, the word ‘love’ has nothing to do with

the emotion we normally feel when we like someone a lot. In the context of tennis, the word

‘love’ comes from the French ‘l’oeuf’ meaning ‘an egg’. In many sports, the egg is

frequently used to symbolise ‘zero’. In cricket, for example, when a batsman gets out for a

zero, we usually say he was out for a ‘duck’. Therefore in tennis, when the umpire shouts

‘love all’, what he means is that the score is ‘zero all’ — neither player has scored a point.

The word ‘deuce’, on the other hand, is used when the scores are level; it suggests that the

two players have scored three points each in the game. In order to win the game, one of the

players has to score two consecutive points. This idea that a player has to win two points in a

row is captured by the word ‘deuce’. It is a corruption of the French ‘deux’, meaning ‘two’.

Anecdote

Tolstoy was a great pacifist and was once lecturing on the need to be nonresistant and

nonviolent towards all creatures. Someone in the audience responded by asking what should be

done if one was attacked in the woods by a tiger. Tolstoy responded, "Do the best you can. It

doesn't happen very often."

Mark Twain, the famous American writer, was travelling in France. Once he was going by

train to Dijon. That afternoon he was very tired and wanted to sleep. He therefore asked the

conductor to wake him up when they came to Dijon. But first he explained that he was a very

heavy sleeper. “I’ll probably protest loudly when you try to wake me up,” he said to the

conductor. “But do not take any notice, just put me off the train anyway.”

When Mark Twain woke up, the train was already in Paris. The angry writer ran up to the

conductor and said, “I’ve never been so angry in all my life.”

The conductor looked at him calmly. “You are not half so angry as the American whom I put

off the train at Dijon,” he said.

Origin of idioms

Bite the bullet

Usage: It is generally used when someone has to endure something difficult or unpleasant

For the uninitiated, this expression was first used in the novel The Light That Failed which

came out way back in 1891. It’s existence came into being from the practice of patients having

to clench a bullet between their teeth for a surgical procedure due to lack of time to use

anesthesia. It acted as a distraction from immense pain. It is also said that this phrase evolved

from the British empire expression ‘to bite the cartridge’, dating back to the Indian Rebellion of

1857. Mind blowing, isn’t it?

Question: Where does the expression "he wears his heart on his sleeve" come from?

Answer: Although the expression first appeared in William Shakespeare's play "Othello", the

saying originated in medieval times. In the King's Court, if a knight was jousting in order to

defend the honor of a woman, it was customary for him to wear a handkerchief in her colors

around his arm to show his loyalty to her.

MATHEMATICS

ARITHEMETIC PROGRESSION

An Arithmetic progression or an arithmetic sequences is a sequence of numbers such that the difference between the consecutive terms is a constant. If the first term of an arithmetic sequence is ‘a1’ and the common difference is ‘d’, then the nth term of the sequence is given by an= a1+(n-1)d

PYTHAGORAS THEOREM

The Pythagoras theorem states that in a right angled triangle let ‘c’ be the length of the hypotenuse and ‘a’ and ‘b’ be the length of other two sides , the theorem can be expressed as the equation a2+b2=c2.

AREA OF TRIANGLE

Area of a Triangle =( ½ x base x height) sq units

HERON’S FORMULA The area of a triangle = 푠(푠 − 푎)(푠 − 푏)(푠 − 푐)Sq units, S= a+b+c

The area of an equilateral triangle having each side is ‘a’ is √3 a2

4 Remainder Theorem: Let f(x) be a polynomial of degree n≥1and let a be any real number.

When f(x) is divided by (x-a , then the remainder is f(a). Factor theorem: Let f(x) be a polynomial of degree n>1and let ‘a’ be any real number.

If f(a) =0 then (x-a) is factor of f(x).

If (x-a) is a actor o f(x) then f(a)=0

The probability of the event E id written as P(E) and P(E)= Number of outcomes favourable to E

Total number of possible outcomes of the random experiment

0≤P(E)≤1 P(not E)=1—P (E) P(E)+P(not E)=1 P(E) is never negative

LINES AND ANGLES

Parallel lines: If two lines lie in the same plane and do not intersect when produced on either side then such lines are said to be parallel to each other.

Transversal: A straight line which cuts two or more straight lines at distinct points called a transversal.

If a transversal cuts two parallel lines then each pair of corresponding angles are equal. If a transversal intersects two parallel lines then alternate angles of each pair of interior angles

are equal. If a transversal intersects two parallel lines then each pair of consecutive interior angles are

supplementary. GOOGOL

The term Googol (10100) was invented by a 9 year old boy Milton Sinotta.
