No Comments Scientists have fabricated improved low cost heavy rare earth-free high Nd-Fe-B magnets, which are in high demand for Electric Vehicles and can make them more affordable. More than 90% of EVs use brushless DC (BLDC) motors made up of rare earth Neodymium Iron Boron (Nd-Fe-B) magnets. Since its discovery by Sagawa in 1984, the Nd-Fe-B magnet has been one […]
No Comments OpenAI has released ChatGPT, a new dialogue language model (LM) based on the GPT-3.5 family series (trained on text and code) and similar to InstructGPT (aligned with reinforcement learning through human feedback). The company set up an online demo which has gone viral among users and reached its first 1 million user accounts in just […]
No Comments Imperialism and aggression in the 20th century culminated in victimizing the centrifugal retaliation which had gone beyond the Karman line. The space race today is not just between 2 countries but among several rapidly growing nations like China, India, Japan, France etc. The 20th-century world wars paved the way for outstanding innovations in space whereas […]
No Comments The turn of the century in the late 1990s that paved the way for the “Information Age” leaves an indelible mark of change on the nature of geopolitics. This change is rapid and has lasting consequences. It can be observed that the fundamental axis on which geopolitics gradually shifted is the axis of technology. When […]
No Comments A unicorn is a privately held startup company with a current valuation of US$1 billion or more, across technology centers throughout the world. These unicorns are primarily located in consumer, technology, finance, hospitality, retail, and communications. Startups are taking advantage of the flood of new technology of the last decade to obtain Unicorn status. With […]
No Comments Union Minister of State for Science & Technology Dr Jitendra Singh informed that Geo-imaging satellite “EOS-03”is scheduled for launch in third quarter of 2021. The EOS-03 would enable near-real time monitoring of natural disasters like floods & cyclones. The information was shared while replying to a question in the Rajya Sabha today. He said that […]
No Comments A group of astronomers have detected a very short, powerful burst of high-energy radiation that lasted for about a second and had been racing toward Earth for nearly half the present age of the universe. The burst detected by NASA’s Fermi Gamma-ray Space Telescope on August 26, 2020, turned out to be one for the […]
No Comments Unlike paper currencies, cryptocurrencies are decentralized i.e there is no central authority that issues, controls or overlooks them. “Block chain” is the underlying technology and the security of cryptocurrencies are backed by computer encryption algorithms like hashing and cryptography giving them the adjective “crypto”-currency. Start-ups are keen on utilizing this as an investing tool which […]
No Comments Scientists at the Indian Institute of Science Education and Research (IISER), Mohali, have used cryogenic technology to achieve a low temperature of 10 milliKelvin or -272.99 degrees Celsius, slightly toasty than the extremely cold world of space where the temperature is as low as 2 milliKelvin (-273.148 degrees Celsius). The temperature achieved by the institute […]
No Comments Professor Amitabha Lahiri of S N Bose National Centre for Basic Sciences (SNBNCBS) showed in a paper published along with Subhasish Chakrabarty, his student, that the geometry of space-time can cause neutrino oscillations through quantum effects even if neutrinos are massless. It was published in the journal ‘European Physical Journal C’. SNBNCBS is an autonomous […]
