Today (November 19, 1936) is the birthday of Arvind Bhatnagar, the founder of many planetariums across India.
Arvind Bhatnagar was born on
November 19, 1936, in Beware, Rajasthan. After completing his postgraduate
studies in Physics, he joined the Uttar Pradesh State Air Force in Nainital in
1958. He worked here until 1961. He received his PhD in Solar Physics in 1964
from the University of Agra while working at the Astronomy at Kodaikanal. Prof.
MK Vainupappu was his mentor for his doctorate. He worked on the Mount Wilson
and Palomar planets in the United States from 1968-70 and was awarded the
Carnegie Scholarship. Bhatnagar worked as a permanent astronomer at the Big
Bear Solar Observatory until 1972, when he owned the California Institute of
Technology in Pasadena, California.
Under the guidance of the
Ahmedabad Theological Seminary, Professor Bhatnagar returned to India in 1972
to establish a solar observatory as a private island in the middle of Udaipur
Lake Padesagar. He chose the place of maximum sunlight in the state of
Rajasthan. He carefully selected the site of the lake, taking into account the
fact that the water of the lake helps to reduce the turbulence of the air
heated by the ground due to solar radiation. The laboratory was transferred to
control of the aerospace industry in 1981 as a result of his continued efforts
to achieve rapid growth. Reconstructed as an International Space Station for
Solar Studies. The research centre he founded is one of six stations that study
the interior of the sun around the world.
The events of the solar eclipse
of October 24, 1995, were another milestone in Dr Arvind Bhatnagar's scientific
achievement. Dr Arvind Bhatnagar travelled and supervised the MiG-25 at an
altitude of 80,000 feet with a speed of 3000 km / h. Minutes of attention are
considered precious minutes. Many unknown facts were then revealed while
peering from the ground. Indian scientists have made an effort to measure the
hitherto unknown exact diameter of the sun by measuring the amount of sunlight
that falls on the earth during an eclipse. The exact size of the sun is still
unknown. Shadow photographers and scientists were used on three Indian Air
Force aircraft. In addition, a pair of Indian Air Force MiG-25 fighter jets
were set up to equip the outside light of the sun and the surrounding ring of
dust to be photographed in as dark a clear sky as possible.
In 1996, Professor Bhatnagar
started an innovative project called SUCHE. (SUCHE is abbreviated in English
with a focus on the experimental, healthy, urban, clean, hygienic environment).
Efforts were made to implement solid waste management with public
participation. He was appointed Commissioner under the High Court order in
connection with the protection of the Udaipur Lake system. Has made significant
contributions to the field of solar astronomy. He established many planetariums
across India. Professor Arvind Bhatnagar is internationally known for his
invaluable contributions to the field of solar astronomy.
He was very involved in creating
awareness about astronomy among the people. With this in mind, he was involved
in the effort to establish various planetariums across the country. Arvind Bhatnagar,
who founded many planetariums across India, passed away on May 18, 2006, at the
age of 69 in Udaipur, Rajasthan. He is considered a scientist and a social
progress reformer.
