Sr. No.  Topics Points to remember… Why in news…???
1. SIMBEX
  • Started as basic Anti-Submarine Warfare (ASW) exercises in 1994, today these exercises have graduated to complex maritime combat drills, including missile and torpedo firings, and shore-based intensive professional exchanges.
  • India and Singapore are working on a trilateral exercise with an Association of South East Asian Nations (ASEAN) country, likely Thailand, and eventually plan to scale it up to a multilateral format.
The 25th edition of the India-Singapore bilateral naval exercise, SIMBEX, has begun at the tri-services command in Port Blair.
2. The RBI Board
  • The RBI Board is a body comprising officials from the central bank and the Government of India, including officials nominated by the government.
  • According to the RBI, the “general superintendence and direction of the affairs and business of the RBI is entrusted to the Central Board” and the Board exercises all powers and does all acts and things that are exercised by the RBI.
  • The Board is also to recommend to the government the design, form and material of bank notes and also when and where they can serve as legal tender.
  • The Board consists of official directors, who include the Governor and up to four Deputy Governors, non-official directors, who include up to ten directors from various fields and two government officials, and one director from each of four local boards of the RBI.
  • The Governor has to call a Board meeting at least six times in a year, and at least once each quarter.
The RBI Board recently entered the news during the public spat between the central bank and the Finance Ministry. One of the reasons for the disagreement was the government’s alleged threat of invoking Section 7 of the RBI Act.
Section 7 basically empowers the government to supersede the RBI Board and issue directions to the central bank if they are considered to be “necessary in public interest”.
3. SpiNNaker
  • SpiNNaker, built at the University of Manchester in the U.K., can model more biological neurons. Biological neurons are basic brain cells present in the nervous system that communicate by emitting ‘spikes’ of pure electro-chemical energy.
  • It is unique as it mimics the massively parallel communication architecture of the brain, sending billions of small amounts of information simultaneously to thousands of different destinations.
  • “SpiNNaker completely re-thinks the way conventional computers work. ,” said Steve Furber, who conceived the idea for such a computer.
It is the world’s largest supercomputer designed to work in the same way as the human brain has been switched on for the first time.
The Spiking Neural Network Architecture machine is capable of completing more than 200 million million actions per second, with each of its chips having 100 million transistors.
4. Oumuamua
  • It was too small to appear as more than just a point of light even on large telescopes, but it was evidently an unusually elongated object that was both rotating about an axis and tumbling along through space, given that its brightness varied dramatically every 7-8 hours — brightest when its full length faced the Earth, near invisible when it pointed towards the Earth.
  • It was going at more than 87 km/second — fast enough to escape the gravity of the Sun. Scientists named it ‘Oumuamua, Hawaiian for “scout” or “a messenger sent from far to reach out to us”.
On October 19, 2017, astronomers operating the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS) 1 instrument in Maui, Hawaii, noticed an unusual object bursting out of the constellation Lyra about 32 million km from Earth, and hurtling across the Solar System towards an unknown destination.
