Science and Technology Mixed Practice — MCQs with Answers (Set 17)

The Court also ordered a committee, headed by retired Supreme Court judge D.K. Jain, to investigate the role of the Kerala police officials involved in the case.

The Saha ionization equation relates a gas’s ionization state to temperature and pressure, letting astronomers read stellar temperatures from spectra.

The Supreme Court ruled the case had been concocted and awarded Narayanan ₹50 lakh in compensation for unnecessary arrest, harassment, and mental cruelty.

The CBI’s 1996 closure report found the espionage allegations unproven and false, leading the court to discharge all the accused.

Nambi Narayanan led ISRO’s cryogenic rocket-engine project, central to India’s GSLV launch vehicle programme, when he was wrongly arrested in November 1994.

Ali received honorary doctorates from Aligarh Muslim University (1958), Delhi University (1973), and Andhra University (1978).

Ali was one of several prominent voices who wrote to the Central Government opposing a hydroelectric project in Kerala’s Silent Valley, calling it “shortsighted.” The project was scrapped and the valley became a National Park.

Ali co-authored, with S. Dillon Ripley, the landmark ten-volume “Handbook of the Birds of India and Pakistan,” covering a decade of work from 1964 to 1974.

Ali held only a B.Sc. in zoology from St. Xavier’s College, having abandoned further formal study. This kept him from an early job at the Zoological Survey of India, which required a postgraduate degree.

Ali’s interest in birds began as a boy, after he shot a yellow-throated sparrow with an air gun and could not identify it.

Bose founded the Bose Institute in Kolkata, on 30 November 1917, considered Asia’s first interdisciplinary research institute.

Bose refused to patent his invention, believing scientific knowledge should be shared freely, not restricted for commercial gain — a deliberate philosophical stance, not an oversight.

Bose invented the crescograph, an instrument that measured a plant’s growth response and speed against gravity, demonstrating parallels between plant and animal tissue responses.

Bose transmitted an electromagnetic wave roughly 75 feet, through two intervening walls, to remotely ring a bell and ignite gunpowder — a year before Marconi’s famous wireless patent.

Bose became the first native Indian professor of physics at Presidency College, Calcutta, after studying at the University of London and Cambridge.

The British Crown knighted him KCIE in 1915, while he was Diwan of Mysore, four decades before the Bharat Ratna.

India declared 15 September as National Engineers’ Day in 1968, six years after Visvesvaraya’s death in 1962.

He founded the University of Mysore in 1916, alongside the State Bank of Mysore and the Mysore Iron and Steel Works, during his time as Diwan.

As Chief Engineer of Mysore from November 1909, Visvesvaraya designed the Krishna Raja Sagar Dam on the Kaveri river.

His self-closing floodgate design was first installed at the Khadakwasla Reservoir near Pune, to stop it overflowing.

At MIT and the University of Texas at Dallas, Rao ran cosmic-ray experiments as a prime experimenter on NASA’s Pioneer and Explorer spacecraft.

On 19 March 2013, Rao became the first Indian inducted into the Satellite Hall of Fame in Washington DC.

Rao’s 1984-1994 tenure as Chairman began the groundwork for the GSLV, alongside guiding the SLV-3, Bhaskara, APPLE, Rohini, and INSAT programmes.

Rao completed his PhD in cosmic ray physics under Vikram Sarabhai, founder of India’s space programme.

Aryabhata launched on a Soviet rocket in 1975, since India’s own SLV-3 launch vehicle wasn’t ready yet.
