FOOTWEAR
FOOTWEAR: _ _ Section-1 Prologue: Shoes are a product of everyday use that everyone in the world owns; there are more than 20 billion pairs of shoes manufactured each year. Shoes have come a long way in the thousands of years since primitive man first donned bark and animal skins. Originally used to protect feet from harsh temperatures and rough land, shoes have evolved into an article of high fashion and style, a sartorial reflection of class, rank, and wealth. Most people think that wheel invention was the greatest event of the ancient time, but shoemaking takes a very high position on that list too. As they say, “you are what you wear.” And there’s a lot that shoes can tell us about a person. Shoes make the man, they say. Throughout human history, we’ve improved, embellished and refined footwear. We’ve created shoes that impress and inspire, and shoes […]
Plane Crash
Plane Crash: “Flying is not inherently dangerous, but to an even greater extent than the sea, it is terribly unforgiving ….” —Captain A. G. Lumplugh, British Aviation Insurance Group ________ Section-1 Prologue: Flight is, and always will be a marvel of human achievement. The opportunity to “spread your wings” and fly is an unbelievable privilege and experience. Airways have undergone a drastic evolution in the past decade, with airplanes becoming the most widely used means of transport across the globe. This is primarily because of the higher reliability, least travel time and a better cost effectiveness of the airways over other modes of transport. In addition to that, airports are traditionally considered as the country’s signature monuments. It showcases to an outsider, the first and the last impression of the country. Commercial aviation transports more than four billion passengers annually on airliners. Aviation is a critical part of national economy, […]
Electric Vehicle, EV (electric car)
Electric Vehicle, EV (electric car): _ The engine of a conventional internal combustion engine car is replaced by an Electric Motor and the fuel tank is replaced by the Battery Pack. Of all the components only the Battery Pack and Electric Motor alone contributes to about more than 50% of the total EV’s weight and the price. __ Section-1 Prologue: A car can be a wonderful thing. It can take you where you want, when you want — even when those places aren’t served by public transportation. In fact, much of modern life would be impossible without cars. They help us get to our jobs, schools, grocery stores or even just to the local shopping mall. Unfortunately, as wonderful as cars are, they also have some serious drawbacks. Two of these drawbacks are that they often cost a lot of money to maintain and they pollute the […]
Are We Animals?
Are We Animals? _____ Man versus polar bear: _ Keeper Julius Latoya shares a tender moment with Kinna, a young orphaned African elephant at the David Sheldrick Wildlife Trust in Tsavo East National Park, Kenya. ______ ______ Section-1 Prologue: Many parents admonish their misbehaving children by saying “stop acting like animals” implying that children are acting in a primitive and thoughtless manner. When my students/patients misbehave, I occasionally tell them that they are behaving like animals. Of course, my critics in India would label my utterances as racist and dehumanizing akin to the Nazis’ persecution of Jews during the Holocaust and torture at the Abu Ghraib prison in Iraq. Many patients hospitalized in some Covid-19 facilities in India complained that their condition was like “animals” at the facility. Most of us grew up eating meat, wearing leather, and going to circuses and zoos. Many of […]
Digital Learning (Digital Education)
Digital Learning (Digital Education): _ _____ Section-1 Prologue: “Lectures are only terrible if you are a terrible lecturer!”. Lectures that are dynamic, evoke emotion, and engage the audience are worthwhile learning experiences. But in this age without technology dynamicity, emotion evoking, audience engagement etc. are all impossible. For our new generation kids born in latest technological environments, everything seems boring when it is not connected with technology, and rather counterintuitively we expect that they would learn under the same old age classrooms systems. Today’s students are digital natives. This is a generation that has never known a world without Google, the internet or even smartphones. Technology is at the center of their lives, touching every aspect of their day-to-day experiences and influencing their decisions. It stands to reason, then, that technology should be a crucial part of their educational experience. In today’s world, digital technology has not yet been applied […]
