3D Printing: ____ In reality 3D printing is quite slow as compared to the figure above! ____ Prologue: The First Industrial Revolution took place from the 18th to 19th centuries in Europe and America. It involved iron and textile industries, along with the development of the steam engine. The Second Industrial Revolution took place between 1870 and 1914, just before World War I and technological advances during this period included the telephone, light bulb, phonograph and the internal combustion engine. The Third Industrial Revolution, or the Digital Revolution, started in 1980s which refers to the advancement of technology from analog electronic and mechanical devices to the digital technology available today. Advancements during the Third Industrial Revolution include the personal computer, the internet, and information and communications technology (ICT). The Fourth Industrial Revolution builds on the Digital Revolution, representing new ways in which technology becomes embedded within societies and even […]
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): _____ ______ 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 […]
Are ordinary people bad? ________ _______ Let me start by giving 3 examples from India: _ _ Example-1 On August 10, 2016 Matibool is on his way home from an overnight shift as a watchman, carrying a cellphone in his hand as seen in the figure above. It is dawn in Delhi. Suddenly, a speeding three-wheeled tempo barrels down on him from behind, knocking him into the air. The driver gets out, sees Matibool’s crumpled body and decides against even approaching him. In a matter of seconds, the driver is back in the truck, and away he goes. As Matibool lay bleeding for an hour, men and women riding in 140 cars and 82 rickshaws would avoid his dying body. So would 181 bikers and 45 pedestrians. At one point, an emergency response van used by the Delhi police drives by. A cycle rickshaw passes his body and stops a […]
Antimicrobial resistance (AMR): ______ ______ Prologue: Within a few days of scraping his leg in a scooter accident in 2009, nine-year-old Brock Wade was in hospital fighting for his life with a methicillin-resistant staphylococcus aureus (MRSA) infection. Once the infection – caused by one of the bacteria most often resistant to antibiotics – has been diagnosed, doctors put him on five different antibiotics. After a month in the hospital, and against all odds, Brock recovered and was well enough to come home. Scenarios such as this case are increasingly being played out all over the world. But not all the thousands of patients that contract drug-resistant bacterial infections every year are as lucky as Brock. And the problem looks set to get worse. While infectious agents are becoming more and more resistant to the medicines that are currently in use, not enough drugs are being developed to combat them. WHO […]
