SCIENCE OF TRUTH

Science of Truth: ______ _____ Prologue: I published article ‘The Lie’ on my website on June 5, 2010 wherein I showed how media lied for several decades by saying that Hollywood icon Marilyn Monroe died ‘childless’ in the year 1962. “Repeat a lie often enough and it becomes the truth”, is a law of propaganda often attributed to the Nazi Joseph Goebbels. Discussion on ‘lie’ is incomplete unless you discuss the ‘truth’. So what is truth?  The question is one of the most ancient in philosophy. It was famously posed by Plato, who asked whether there exist eternal truths or whether, to the contrary, man is the measure of all things. Diderot and d’Alembert, in their Encyclope´die (1751–1772), proposed a simple and straightforward answer: truth consists in conformity of our judgments with things. In other words, something is true when there is a fit between thought and object: This implies […]

SYNTHETIC BIOLOGY (SYNBIO)

Synthetic Biology (synbio): _______ Scientists Elizabeth Allman and Kristin O’Brien teach a course in synthetic biology at the University of Alaska Fairbanks. O’Brien said that the goal of synthetic biology is not to build “better organisms” but rather to create biological machines. _______ Prologue: The advent of digital technology is considered one of the biggest revolutions of all time for how quickly and deeply it changed the world forever. Even more powerful revolution is coming, which goes under the name of synthetic biology. The potential of this discipline is very well understood in the biological scientific world. It is time I make general public aware of the impact it will have on our lives. Synthetic biology brings together a bewildering number of disciplines: biotechnology, molecular biology, systems biology, biophysics, computer engineering, genetic engineering, and more. Synthetic biology will allow scientists and engineers to create biological systems that do not occur […]

ARTIFICIAL INTELLIGENCE (AI)

Artificial Intelligence (AI): _____ ______ Prologue: Mention Artificial Intelligence (AI) and most people are immediately transported into a distant future inspired by popular science fiction such as Terminator and HAL 9000. While these two artificial entities do not exist, the algorithms of AI have been able to address many real issues, from performing medical diagnoses to navigating difficult terrain to monitoring possible failures of spacecraft. In the early 20th century, Jean Piaget remarked, “Intelligence is what you use when you don’t know what to do, when neither innateness nor learning has prepared you for the particular situation.”  A 1969 McKinsey article claimed that computers were so dumb that they were not capable of making any decisions and it was human intelligence that drives the dumb machine. Alas, this claim has become a bit of a “joke” over the years, as the modern computers are gradually replacing skilled practitioners in fields […]

DIGITAL TRANSACTION

Digital transaction: ___ ____ Prologue: History of banking dates back to 2000 B.C. Archaeologists believe that depositing and lending have always been human way of business and economy during renowned Roman, Chinese, and Indian empires. In fact, if we really think about it, there can actually be no trusted way of keeping earned money safe to be used when required other than a trusted group that also provides interest on such deposits. From that time banks and their ways have evolved tremendously. Computing revolution has been the biggest step forward here. For what was confined to signatures and psychical presence, has now been replaced by plastic money and virtual presence. John Shepherd-Barron, the Scotsman is credited with inventing the world’s first automated cash machine. Shepherd-Barron said once that he came up with the idea of the cash machines after being locked out of his bank. Plastic bank cards had not […]
