Skill Forum India explores that in fast-emerging data-driven economy, Internet of Things (IoT) will play a crucial role because of IoT, there was lot of demand for smart devices. The devices would connect to the real world through IoT and gave details how Uber had turned into third largest automobile company in the world by using digitisation and Alibaba became the largest retail company. Overall benefit and lifetime ownership cost as well as diagnostic analysis based on data were changing the entire world.
Three crypto-currencies you need to know about and what they stand for:
(1 ) Bitcoin (BTC):
This is the one that started it all. Despite widespread community interest, the largest market cap among all cryptocurrencies and consistent public scrutiny, Bitcoin has held firm. It is the first decentralised digital currency that used a peer-to-peer network for transactions between users. Bitcoin’s growing user base and relatively large block time (the time taken for one block in the blockchain to be ‘mined’ by the miners that keep the blockchain up and running) have led to delays in transactions on the network and increasing transaction fees.
(2) Litecoin (LTC):
Founded in 2011 by ex-Google employee Charlie Lee, Litecoin is often referred to as the silver to Bitcoin’s gold. This is one of the go-to currencies used today for transactions, thanks to its faster block time of around 2.5 minutes, compared to Bitcoin’s 10 minutes, enabling much faster exchanges between users. Litecoin’s algorithm also makes it difficult to build Application-Specific Integrated Circuits (ASIC), the likes of which are used to mine Bitcoin, and have been criticised for the massive electricity consumption that goes into mining the cryptocurrency, leading to long-term scalability problems.
( 3 )Ether (ETH):
Ether was until recently the second-largest cryptocurrency in terms of market cap. It is the cryptocurrency used in the Ethereum network, upon which ‘smart contracts’ can be built and executed. The main application for this platform is the use of smart contracts between parties, that usually require an intermediary for the purposes of trust or verification (such as the services performed by Airbnb or Uber). The potential real-world applications can be built by Ethereumblockchain, and the subsequent elimination of middlemen, have made it one of the hottest properties in the blockchain business, and have seen the price of Ether rise massively over the past few months.

Challenges in Nobel Prize 2017 for Physics
Skill Forum India explore that the challenge in Nobel Prize for physics 2017 was to separate the larger noise contribution and reduce the effect of ground vibrations (gravitational waves). These ground vibrations create noise, the beauty of experiment was to reduce magnitude of vibrations by a factor of one hundred million Indian Science Skilling contributed in it as the steel tubes used in this experiment are being made at Institute for Plasma Research in Ahmadabad. Nobel Prize 2017 for physics is for LIGO-VIRGO collaboration for having directly observed gravitational waves for the first time. The instrumentation to differentiate and detect this faint signal from the noise was a crucial contributions. The first gravitational waves that were detected were small fluctuations of space-time caused by a violent merging of two black holes about 1.3 billion light years away. We know that light bends due to a change in refractive index of the air near hot objects like a heated asphalt road. Light also bends when space-time curves due to the presence of massive gravitational fields. When a gravitational wave is incident on the detector, the laser beam behaves in a similar manner. One main difference is the magnitude. The difference between bending of light in cool air and hot air is about 1%, whereas the bending caused by a gravitational wave is about one billion times smaller than the thickness of a human hair. LIGO’s interferometers(photo detector) are a ten orders of magnitude improved as compared to the first interferometer made by Albert Michaelson in 1881, which was able to measure a displacement in nanometres. Under the high degree of vacuum needed, stainless steel has the problem that the hydrogen separates out. So a special stainless steel called low-hydrogen stainless steel was needed. The steel tubes are also used to house the lasers and have to be very clean. These are being made at Institute for Plasma Research in Ahmadabad. In all, the tubes measure 8 km in length and have a diameter of 1.2 m.
Challenges for the Engineering Programmes in India
Skill Forum India find that there are many challenges for the Engineering programmes in India that do nothing to address the challenges of globalisation. They may become irrelevant due to factors like a lack of adequately trained faculty. There is a need to improve the quality of engineering education — particularly by supporting ongoing faculty professional development. It is vital that educational institutions work closely with employers and industry to keep their curricula relevant. We have a number of global challenges in the world today: food security, clean air, clean water, energy, sustainability, healthcare, transportation, climate change, education, and so on. Engineers continue to find innovative solutions to these global challenges that confront society. Global education needs to be integrated into the engineering curriculum to achieve maximum impact on addressing societal needs. Programmes that do nothing to address the challenges of globalisation will soon be irrelevant. As we advance technologically and come up with innovative solutions that employ heuristics, AI, and Robotics, now more than ever we need engineers who understand the humanistic values and the impact of their solutions on society. There will always be a need for engineers who can create that next generation of solutions that address the contemporary issues of their time.

Internet of Things (IoT) :
IoT revolution, which will include autonomous cars, robots in factories, smart cities, virtual reality immersive experiences, smart public transport, remote healthcare, and much more. IoT devices will be powered not by 3G or 4G, but by 5G. Hence, 5G Is Closer Than You Think, And find How It Will Change The World. To make the future possible, to make IoT and the awesome potential of IoT-enabled technology a reality, we need 5G. 3G has meant faster access, and 4G has given us even better reliability and speed. To keep up with the demands of use cases like IoT, 5G technology needs to be built from a wholly different mettle. While 5G will definitely feature a quantum increase in communication speeds and lower latency, it’s not about mere ‘faster’ alone, but about absolute transformation — metaphorically, moving to 5G from today’s mobile networks will be like going from black & white to colour or from reality to virtual reality. Quite simply, it will be a transformation in connectivity and communication the world has never seen before.
In presence of 5G, during IPL match where you could barely send a tweet because thousands of others were connected to the same cellular tower; in 5G, thanks to a decentralized approach, it would be as if each user has his or her own tower with ample bandwidth to connect to. Even from a crowded stadium you could stream HD video with ease. IoT devices can be connected through a communication fabric that is constantly available, instantly scalable and highly secure. Distance will collapse, the world will be served up on-demand. Access will become a fundamental feature of our lives in the age of 5G; always-on, context aware and intelligent, thanks to the use of Artificial Intelligence technologies that will complement 5G.
