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 […]
SCIENCE OF MUSIC
Science of Music: _____ “Happy Birthday, Mr. President” is a song sung by actress and singer Marilyn Monroe on May 19, 1962, for President John F. Kennedy at a celebration of his 45th birthday, 10 days before the actual date (May 29). The event marked one of Monroe’s final public appearances; she was found dead in August 1962 at the age of 36, and JFK was assassinated the following year. _____ Prologue: The fascinating thing about music is that technically- in a very literal way- it doesn’t exist. A painting, a sculpture or a photograph can physically exist, while music is just air hitting the eardrum in a slightly different way than it would randomly. Somehow that air- which has almost no substance whatsoever- when vibrated and when made to hit the eardrum in tiny subtle ways- can make people dance, love, cry, enjoy, move across country, go to war […]
VULNERABLE PLAQUE
Vulnerable Plaque: ____ ____ Prologue: Worldwide more than 17 million people die every year from cardiovascular disease (CVD) with this number projected to increase to over 23 million by 2030. The vast majority of acute ischemic vascular events occur in relation to an underlying atherosclerotic plaque. Atherosclerotic plaque represents the hallmark lesion of atherosclerosis. Plaque rupture is the dominant initiating event, responsible for 60–70% of acute coronary syndromes (ACS), while plaque erosion is responsible for most of the remainder. Irrespective of the mechanism, the consequence is exposure of a thrombogenic substrate to circulating blood. This in turn triggers platelet aggregation and the coagulation cascade which compromises vascular blood flow resulting in downstream end-organ ischemia and infarction. These events occur abruptly and often without warning. Despite major advances in treatment of coronary artery disease patients, a large number of victims of the disease who are apparently healthy die suddenly without prior […]
