The Book On the discovery of The Periodic Law and on relations among the atomic weights written by John Alexander Reina Newlands was published in 1884. It has 70 pages.

The cassette is about a one-day seminar on the world year of physics that is held at IIA Auditorium.

This item was donated by Cherry Armstrong Great-Great Grand daughter of N.R.Pogson in 2006. We can see that Mr. Pogson was standing with Lucy Sylvia, An unknown Indian and Louise Camilla. Some small children were also seen in the photo seated infront, who probably be Charles Albion, Isis, and Robert Owen.

This item was about the Padma Bhushan Award honoured to M.K.Vainu Bappu on 28-03-1981. The Padma Bhushan is the third-highest civilian award in India. It is awarded for "distinguished service of a high order". The award was established on January 2, 1954.

This item was the painting of Kodaikanal Observatory by an unknown artist in 1909.

Astronomer William Stephen Jacob of India made important advances in the study of Saturn. He made observations of the Sunnian system and reported his findings, which included determining the elements of Saturn's satellites and Jupiter's adjusted mass. In 1852, he and William Lassell observed the transparency of Saturn's "dusky ring" almost simultaneously. In 1861, James Breen truncated Jacob's planetary observations. The Indian government paid for the printing of his books on the Saturnian system. Important new information about Saturn and its moons was made possible by these observations and calculations. One of his best-known pieces is a sketch he made on November 15, 1852, of Saturn. Using the Madras Equatorial, this drawing was created. W. Forrest then etched it. The illustration caught the appearance of Saturn on that specific date, providing valuable insights into the planet's features and characteristics at that time.

The Observations conducted at Kavalur during the 10 March 1977 Uranus occultation of SAO158687 revealed, apart from the occultation by a satellite system known as the e ring, a decrease in the star's brightness near the moment when the planet's atmosphere could have triggered the occurrence. Since then, a theoretical explanation for the genesis of the a, ß, ?, and d rings has been put out in addition to the identities of these rings becoming firmly established. After thoroughly analysing the Kavalur photoelectric record, they provide several novel elements of Uranus' satellite ring system.

This letter was about Kavalur observatory from its genesis to its commencement in 1972. its achievements throughout the whole journey.

This letter was about Kodaikanal Observatory's position & surroundings and also talks about scientific celebrities contribution and visits of Dr. Homi Bhabha, Dr. S. Chandrasekhar.

This item was about the sketch of the path of a total solar eclipse that occurred in India in 1868. It depicts the Peninsula of India and shows the track of the Moon's shadow during the eclipse on August 17, 1868. The sketch was created by V.T. & A.K. Johnston in Edinburgh and includes scalar measurements at the bottom.
