Welcome to the 3 Books To Know series, our idea is to help readers learn about fascinating topics through three essential and relevant books. These carefully selected works can be fiction, non-fiction, historical documents or even biographies. We will always select for you three great works to instigate your mind, this time the topic is: Time Travel. - Time Machine - HG Wells.- Anno Domini 2071 - Pieter Harting.- A Connecticut Yakee In King Arthur's Court - Mark Twain. Marty McFly and Doc Brown owe thanks to H. G. Wells. It was he who invented the concept of time travel in a vehicle and with controlled trajectory. We will see in other works that before that time travel was accidental and inexplicable. Pieter Harting imagines a journey to 200 years after his time. The Londinia of 2071 is close to the reality we have today: mega-cities, air conditioning, electric vehicles, etc. Harting work makes us reflect on the predictive ability of futurologists, as well as their influence on the creation of reality. The comedy of Mark Twain presents an interesting method of trip to the past: a blow to the head. The traveler will stop in medieval England and know King Arthur himself. The book is a satire of romanticized ideas of chivalry, and of the idealization of the Middle Ages. This is one of many books in the series 3 Books To Know.If you liked this book, look for the other titles in the series, we are sure you will like some of the topics.
