What are quantum repeaters OIn standard communications networks, devices called repeaters briefly store and retransmit signals to allow them to travel greater distances. DOne of the holy grails in science is to be able to use the quantum state of material for communication purposes as these offer potentially unbreachable security. OHowever it's hard to find materials that can physically store such information. ORecently, scientists have stumbled upon diamonds which could serve as quantum repeaters for networks based on qubits OBy substituting some of the carbon atoms in diamonds with silicon, they claim to be able to make quantum repeaters OThe neutral silicon vacancy is good at both transmitting quantum information using photons and storing quantum information using electrons OThese are essential ingredients in creating the essential quantum property known as entanglement which is the key to quantum information's security. Quantum security is bulletproofed by -the 'observer effect'. Observing or measuring an object changes its quantum state, when the observer interacts with it.
Nothing but lies: fake videos, rumour set off the lynch mobs Over 20 people have died in mob attacks triggered by fake news, and experts say social media should deploy technology to stop the mischief WhatsApp and its owner Facebook could look for certain keywords in messages sent on WhatsApp and warning people that they might be getting misinformation." Govt steps: OThe Home Ministry asked the States and Union territories (UTs) to check incidents of mob lynching fuelled by rumours of child-lifting on social media. OThe government directed WhatsApp to immediately take steps to prevent the spread of "irresponsible and explosive messages." Oln the past, it has asked the U.S. to bring pressure on social media giants to install servers in India, but the proposal was turned down. o if the servers are in the country where the government is located, It would help in that "more control can be imposed by a government on social media giants."
Methods to check fake news OPost counter-videos clarifying the actual position DRegister the offences. OAt the heart of this problem is a lack of media literacy, with people believing rumours rather than credible media sources. The government needs to invest much more resources into education, of children and adults alike, in media literacy. Likewise, the government needs to push social media giants to work hard on fighting misinformation, and hold them accountable for taking meaningful steps. Finally, the government can get social media giants to trace the source of fake news stories, and hold their perpetrators accountable for the consequences,". RBI's limited powers in checking malfeasance at government banks. The RBI cannot remove their directors or management, can do little to hold their boards accountable, and cannot force mergers or liquidation of these banks.
The low-down on India-Iran oil trade Iran has always been one of India's main suppliers of oil, second only to lraq and Saudi Arabia India Iran's biggest buyer after China, and as a result, a target for the US. which has declared a campaign to "isolate Iran" after the Trump administration withdrew from the multilateral nuclear deal OFor India, which has been told along with other buyers to take oil imports to "zero" by the cut-off date of November 4, its decisions on procuring Iran oil this point onwards is not so much about securing energy as it is about securing India's standing in the world. o If it rejects U.S. pressure, it risks sanctions as well as incurring the displeasure of its all-powerful friend and defence partner. o If it yields, it risks its relationship with traditional partner Iran, access to important trade routes through Chabahar and the International North South Transport Corridor (INSTC), as well as its international reputation.
How did it come about? OIn 2012, when the Obama administration wanted to maximise pressure on Iran in order to secure the nuclear deal or the Joint Comprehensive Plan Of Action, it had sent a similar tough message to New Delhi, albeit more discreetly than the Trump administration has. DIndia agreed to cut oil imports by 15% subsequently, but asserted its autonomy Three months later, the then PM Manmohan Singh, even visited Tehran to attend the Non-Alignment Summit, despite U.S. objections Eventually, New Delhi operationalised a 'rupee-rial, mechanism, under which half of what it owed Tehran for oil imports would be held in a UCO Bank account and made available to Iranian companies to use for any imports from India, an arrangement the Narendra Modi government is seeking to re-energise.
Why does it matter? But 2018 is not 2012, and the stakes are higher for the government. Ties with the US. are under strain over several issues, including US trade tariffs and India's defence procurement from Russia, and a major divergence on Iran will exacerbate the problem with India's biggest trading partner and fastest growing defence partnership. Moreover, in an increasingly globalised world, where Indian companies compete, any US. sanctions will make it hard for refiners, insurers and transport companies to facilitate oil trade, even if India wishes to continue it. [ ] On the other hand, India's investment in the Iranian relationship has increased, making a turnaround much more difficult OJust five months ago, New Delhi rolled out the red carpet for Iran's President Hassan Rouhani and committed itself to increasing its oil off-take by 25% this year, as part of easing negotiations for the Farzad-B gas fields India is keen to buy a stake in. OIndia has also committed itself to investing S500 million to build berths at Chabahar's Shahid Beheshti Port, and $2 billion to build a rail line through the Zahedan province to Afghanistan, in an effort to circumvent trade restrictions by Pakistan Iran's other oil importers, China and Turkey, have said they will not accept the US's diktat.
What lies ahead? DIn the next four months, one can expect complex negotiations between New Delhi and Tehran, and New Delhi and Washington. OA U.S. team is expected in Delhi this month, and while a senior State Department official ruled out "waivers or licences" to any country, he did hold out the hope that some flexibility might be negotiable "case-by-case" for countries that agree to reduce oil intake from Iran Mr. Rouhani, who is on a European tour discussing ways to retain the JCPOA, has warned of dire consequences if the U.S. succeeds in having Iran's oil exports cut, as this is a "national security" issue OWhile India's oil supplies are diversified, its options in this game of diplomatic brinkmanship are narrowing.
Privatise all political parties The NITI Aayog chief recently made a brilliant suggestion O Instead of gratitude for expressing a bold idea, his comments provoked outrage. Everyone apparently thought he wanted to sell India's family jewels to the cheapest crony capitalist. All he said was that India should hand over its schools, colleges and jails to the private sector something long overdue. O Thanks to electoral bonds and last year's amendments to the Finance Act, today any money bag anywhere in the world can anonymously invest any amount in the Indian political market. India is the fastest growing political market in the world. Political parties spent a total of 10,000 crore in the 2009 Lok Sabha polls-more than double the 4,500 crore that was spent in the 2004 elections. O If you thought that was a lot, they spent in the 2014 parliamentary elections three times what they did in 2009, burning up an estimated K30,000 crore Clearly, electoral politics, along with the allied industries of tax evasion, black money generation, and money laundering, is one of the best performing sectors in the Indian economy. DSince elections these days take place round the year, our much maligned political parties are actually the country's biggest job creators, with millions of people finding year-round employment as social media trolls, fake video producers, WhatsApp admins, lynch mob coordinators, offence- takers, rally audiences, cash dispensers, alcohol distributors, etc.
Value of a tree Way back in 1979, Dr. T.M. Das of Calcutta University estimated that the monetary value of a tree, during a life span of 50 years, amounted to about $2,00,000 (at 1979 rates). O This was based on the amount of oxygen it produces, the fruit or the biomass and the timber it offers when felled and so on For every 1 gram that a tree accumulates as it grows, it generates about 2.66 grams of oxygen. O "trees and plants silently carry out their daily routine years after years, o stabilizing the soil, recycling nutrients, cooling the air, o modifying wind turbulence, o intercepting the rain, absorbing toxins, reducing fuel costs, o neutralizing sewage, increasing property values, o promoting tourism, o encouraging recreation, o reducing stress and improving personal health as well as providing food, medicine and accommodation for other living things".
