Science is so much fun, isn’t it? As are our histories, and the natural world around us. There is so much to know; so many discoveries and innovations are being made everyday. Everyday, we live our lives a bit differently. And isn’t it a joy to put together the puzzle pieces to figure out how and why? This edition of Knowledge casts light on some such important pieces, pieces from pasts and futures. Take our cover story in Robots Like Us (pg 26). It will give you a glimpse into a not too distant world where robots will be a normal part of our households. Perhaps something like in the movies AI and Bicentennial Man? Read about the innovators and the scientists who are tinkering away to make machines more like humans. Or read about Babur (pg 72), the first of the Moghuls, who changed the course of India like no one else did. Find out about the big questions that astronomers and physicists grapple with about our Universe. From questioning the Big Bang to chasing the mysterious Dark Energy. And for those who just thought sci-fi thrillers were just movies, think again – and read The Trouble With Time Travel (pg 62), where John Gribbin explores mind boggling concepts from the film Back to the Future that have scientists hooked. This past month marked 70 years since the Hiroshima bombing. On August 6, 1945, the Atom Bomb was dropped on an unsuspecting city by the United States and the destruction that followed has been unparalleled in history. Read about what happened that day, and how humankind overcame its darkest hour in Hiroshima: Rising From the Ashes (pg 44). Happy Reading
