National Librarian Day 12 August

 


Dr.S.R. Ranganathan

The National Librarian’s Day celebrated on 12th August on the birth anniversary of Padmashri Dr. S. R. Ranganathan, the father of Library Science in India.


Biography of Padmashri Dr.S.R.Ranganathan


Ranganathan, born on 12th August 1892, came from a moderate background in British-ruled India. He was born in the small town of Shiyali (now known as Sirkazhi), in the state of Tamil Nadu in southern India.
Ranganathan began his professional life as a mathematician; he earned B.A. and M.A. degrees in mathematics from Madras Christian College in his home province, and then went on to earn a teaching license. His lifelong goal was to teach mathematics, and he was successively a member of the mathematics faculties at universities in Mangalore, Coimbatore and Madras (all within the span of five years). As a mathematics professor, he published a handful of papers, mostly on the history of mathematics. His career as an educator was somewhat hindered by a handicap of stammering (a difficulty Ranganathan gradually overcame in his professional life).

He was a university librarian and professor of library science at Banaras Hindu University (1945–47) and professor of library science at the University of Delhi (1947–55). The last appointment made him director of the first Indian school of librarianship to offer higher degrees. He was president of the Indian Library Association from 1944 to 1953. In 1957 he was elected an honorary member of the International Federation for Information and Documentation (FID) and was made a vice-president for the life of the Library Association of Great Britain.The Government of India awarded Padmashri to Dr. S.R. Ranganathan for valuable contributions to Library Science.

Five Laws of Library Science:
• Books are for use
• Every reader his/her book
• Every book, its reader
• Save the time of the reader
• A library is a growing organism

August 12th is being celebrated as National Librarian’s Day in India, in remembrance of national professor of library science, Dr S R Ranganathan (1892-1972), who had spearheaded the library development in India.

Hiroshima and Nagasaki Day





Hiroshima and Nagasaki DAY
6 and 9 August 1945

The annual peace memorial ceremonies in Japan serve as a powerful reminder of the catastrophic effects of nuclear weapons and highlight the global commitment to preventing their use and testing. The atomic bombings of Hiroshima and Nagasaki at the end of World War II stand as the only instances of nuclear weapons used in conflict, causing immense devastation and creating a unique group of survivors known as hibakusha. These individuals provide firsthand accounts of the horrors of nuclear warfare, emphasizing the profound human cost and the urgent need for disarmament.

The Impact of Atomic Bombs

Historical Context and Bombings

On 16 July 1945, Robert Oppenheimer and his team conducted the first atomic bomb test in New Mexico. As World War II continued, the U.S. planned to use nuclear weapons against Japan. On 6 August 1945, at 08:15, the first atomic bomb, "Little Boy," was dropped on Hiroshima. This gun-type bomb used uranium-235 and produced an explosion equivalent to 15 kilotons of TNT. The explosion created a fireball with temperatures reaching 7,000 degrees Celsius and shockwaves traveling faster than the speed of sound, causing widespread destruction and loss of life.

Following the blast, black rain laden with radioactive fallout contaminated the area, affecting those who ventured near the epicenter. Three days later, on 9 August 1945, a second bomb, "Fat Man," a plutonium-based device, was dropped on Nagasaki after the original target, Kokura, was obscured by clouds. The combined bombings resulted in an estimated 166,000 deaths, primarily among civilians.

Legacy and Hibakusha

The hibakusha, survivors of the bombings, offer poignant testimonies of their experiences, serving as powerful advocates for nuclear disarmament. Their stories underscore the lasting physical and psychological impacts of nuclear warfare.

Nuclear Testing and the Push for a Ban

Since 1945, over 2,000 nuclear tests have been conducted, leading to the proliferation of nuclear arsenals far more powerful than the bombs dropped on Hiroshima and Nagasaki. Public pressure and diplomatic efforts culminated in the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which opened for signature in September 1996. The CTBT aims to ban all nuclear test explosions globally, marking a significant step toward a safer, nuclear-free world.

The peace memorial ceremonies in Japan, the testimonies of the hibakusha, and the existence of treaties like the CTBT are vital reminders of the need for continued efforts to achieve global nuclear disarmament and ensure that the devastation experienced in Hiroshima and Nagasaki is never repeated.
