The cells of the raw fruit or vegetable are tightly packed
and are held rigidly together by a carbohydrate called pectin which forms a
strong bond with the walls of the coils and cements the cells together. As the
fruit ripens, enzymes in the cells dissolve the pectin. When this happens the
cells are no longer lightly bound to each other and the fruit becomes soft to
the touch. Healing also dissolves the pectin. This is why vegetables and fruit
become soft when cooked.

Taking the Temperature -thermometer
When you have a fever, the temperature is taken with the
help of a thermometer. The bulb of the thermometer is normally placed under the
tongue or in the armpit or groin. What's the reason? For a correct reading of
body temperature, the bulb of the thermometer (which contains mercury) has to
be in direct contact with the body's surface. If the thermometer is placed simply
inside the mouth, it may not give a correct reading, as the bulb may not be in
contact with the tongue. In such a case the temperature recorded will be that
of the air and saliva in the mouth.

S. RAMANUJAN
Ramanujan was one of the greatest Indian mathematician after
Bhaskar and Bramhagupta. He is known for the Ramanujan prime and Ramanujan
theta function. He made substantial contributions to number theory, infinite
series and continued fractions .The number 1729 is called the Ramanujan number
. His mathematical invention of -Rieman Zeta function finds applications in
building high powered quality nuclear reactors. His mathematical formulae have
applications in crystallography and string theory. The year 2012 is celebrated
in India as the National Mathematical year to commemorate 125th birth
anniversary of S. Ramanujan. A postal stamp was issued by the Government of
India in his honour.
S.N.BOSE – Satyendra Nath Bose
The announcement of the discovery of God particle i.e-Higgs
boson has brought the name Indian scientist— Satyendra Nath into global fame. The
Higgs boson has been a focus of ,great
scientific speculation since long time. Recently .a British physicist, Dr
Sharon Ann Holgate termed Prof. S.N.Bose as the 'particle Man', and declared
that he should have been awarded the Nobel prize in physics. The S.N.Bose
National Center for Basic sciences, an autonomous research institute. under the Department of Science and Technology, Government
of India was established in 1986 in his honor . The Government of India issued a
postal stamp to pay a tribute to Dr. S. N. Bose.
JAGADISH CHANDRA BOSE
Apart. from being a great physicist. Sir J.C.Bosc was also a great botanist, archaeologist and
early writer of science fiction stories. He was the first Indian scientist who
proved experimentally that both animals and plants are sensitive to heat,
light, cold, noise and other external stimuli. He designed a very sensitive in
strum ent—Creseo graph. capable of recording and detecting the minute responses
of the plants due to external stimulants. He wanted that Indians should cultivate
scientific culture .J.C.Bose was honoured in India as well as abroad. He was
elected as a Fellow of the Royal Society London in 1920. He founded the Bose institute in 1917. which is a
premier research institute in the field of physics, chemistry. Botany. Microbiology.
plant molecular and cellular Genetics. immunotechnology and Environmental science
etc• The Government of India honored him by issuing a postal Stamp in his
name.

C.V. RAMAN (1888-1970)
C.V. RAMAN (1888-1970)
Chandrasekhar Venkat Raman discovered Raman effect i.e the concept of molecular
diffraction of light and won Nobel prize in physics in 1930. Every year on 28th
February the National Science Day is celebrated in India to commemorate the
discovery of the Raman effect. Raman effect has been proved of utmost importance
in understanding the molecular structure of chemical compounds. C.V.Raman was
awarded Bharat Ratna and the Lenin Peace prize. His remarkable achievements brought international recognition and glory to Indian science . The Government
of India released a postal stamp in his honor.
PRAFULLA CHANDRA RAY
PRAFULLA
CHANDRA RAY (1861 – 1944) Dr P.C.Ray
was the legendary Indian Chemist, academiclan
, and an entrepreneurs.. He was the founder of The Bengal Chemical Works India’s first pharmaceutical company. He discovered mercurous nitrite and
Indian Calcium tonic. Apart from o great scientist, he was also a staunch
freedom fighter and a great science popularizer. His book the Life and Experience of A Bengali Chemist was
popular during British rule in India. He had a strong faith in Indian culture
and Mahatma Gandhi. Acharya Prafulla Chandra ray was a con-temporary Indian scientist and a
close friend of Sir J.C.Bose. The Government of India paid a fit tribute by
releasing a postal stamp in his honor.
