The Enigma of COVID-19:
The Enigma of COVID-19: _____ Caveat: Medicine is an ever-changing science. As COVID-19 pandemic is continuing worldwide, new research and clinical experience broaden our knowledge and necessitates changes in prevention and treatment. I have quoted sources believed to be reliable in their efforts to provide information that is complete and generally in accord with the standards accepted at the time of publication of this article. However, in view of the possibility of human error or changes in medical sciences, readers are encouraged to confirm the information contained herein with other sources. ______ Prologue: An epidemic happens when a disease spreads between large numbers of people in a short period of time. When an epidemic goes global, it is called a pandemic. The 1918 influenza pandemic was the deadliest event in human history (50 million or more deaths, equivalent in proportion to 200 million in today’s global population). […]
QUANTUM COMPUTING
Quantum Computing: _ Note: As a doctor myself, I am on duty treating patients during Coronavirus pandemic and national lockdown. Whatever spare time I have, I utilize it for providing education through my website. Can Quantum Computing help us to respond to the Coronavirus? Quantum computing can be applied to work toward vaccines and therapies as well as epidemiology, supply distribution, hospital logistics, and diagnostics. By harnessing the properties of quantum physics, quantum computers have the potential to sort through a vast number of possibilities nearly instantaneously and come up with a probable solution. How? Read the article. ____ ____ Prologue: Quantum theory is one of the most successful theories that have influenced the course of scientific progress during the twentieth century. It has presented a new line of scientific thought, predicted entirely inconceivable situations and influenced several domains of modern technologies. After more than 50 years from its inception, […]
CYBERCRIME
CYBERCRIME: ____ This educational website was hacked by cyber-criminals on 7 February, 2017 and their threat note was posted on website as shown below: ____ Prologue: Former Chief Justice of India R M Lodha received an email from his friend Justice B P Singh seeking immediate monetary help of Rs 100,000 for the treatment of his cousin. The email said Singh was unavailable over the phone and that was why he was emailing for help. This was not the first time they were emailing each other and an unsuspecting Justice Lodha immediately transferred the money in two transactions at the account number given in the email. Justice Lodha had the shock of his life when he later received a mail from Singh that his email was hacked and Justice Lodha was cheated of Rs 100,000 by a cybercriminal. The world of internet today has become a parallel form of life […]
5G
5G ___ ___ Prologue: Today’s wireless networks have run into a problem: More people and devices are consuming more data than ever before, but it remains crammed on the same bands of the radio-frequency spectrum that mobile providers have always used. That means less bandwidth for everyone, causing slower service and more dropped connections. The rapid increase of mobile data growth and the use of smartphones are creating unprecedented challenges for wireless service providers to overcome a global bandwidth shortage. As today’s cellular providers attempt to deliver high quality, low latency video and multimedia applications for wireless devices, they are limited to a carrier frequency spectrum ranging between 700 MHz and 2.6 GHz. Carrier frequency is the basic operative frequency of radio wave that carries information (voice, video, data) from one place to another place by modulation. A modulated carrier radio wave, carrying an information signal, occupies a range of […]
POPULATION PROBLEM
Population Problem: _ _ Prologue: In an interview given to Economic Times, JRD Tata had reminisced how Nehru once retorted to his concerns on rising population. “Nonsense, a large population is the greatest source of power of any nation,” the first prime minister of Independent India is believed to have told the industry doyen. Subsequently India’s bulging population was seen as threat to the country’s future so much so that Nehru’s grandson, Sanjay Gandhi, ran a controversial campaign of forced sterilization during the emergency (1975-77). Their present Prime Minister Narendra Modi red-flagged population explosion in the course of his Independence Day speech. Mainstream politicians, journalists, and academics frequently avoid discussing population issues since notions about population are often seen as being politically or ideologically motivated. As a result, population debates are generally argued from the fringes. Some groups characterize population growth as a Ponzi scheme, whereby increasing numbers of youth […]
