Hi guys, i going to show you wich was the las book i read, this was a book that consumed me and i finish it in only tow days, the title of this book is "the good themselves" by Isaac Asimov, one of the most recognized and prolific writers of Science fiction of all times. The books talks about a not too distant future where the humanity has found an alien race how lives in a paralel universe where the laws of phsics are completely distinct, this diference permit then, create a machine wich can produce los of free energy, and the story is developed arround of the implicances that this machine bring for both universes, creating and intrincade web of scientifics and philosophical arguments.
