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 […]

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 […]
