ste es el mejor libro de divulgaci n cient fica que he le do sobre relatividad Claro y accesible.Muy recomendable El cap tulo final sobre viajes en el tiempo es genial. In the late 1700s and early 1800s African slaves in Georgia often escaped, making their way to Florida where they taken in by Seminole tribes, becoming ostensibly Seminole slaves It was not a master slave relationship as the Africans had endured in the United States The relationship was symbiotic the slaves and the Seminoles lived cooperatively and harmoniously and had mixed race offspring Eventually the black Seminoles fought beside their kinsmen, defeating the United States Army in the first 1817 1818 , second 1835 1842 , and third 1855 1858 Seminole wars The Seminoles were never defeated and to this day, technically and even though Seminoles fought for the United States in the First and Second World Wars, a state of war exists between the United States and the Seminole people Some of the black Seminoles, led by Chief John Horse, left with other Seminoles, transported by the U.S army to Oklahoma From there many migrated to Mexico and eventually many of those returned to fight on the side of the Union during the Civil War It should not be surprising to learn that these black Seminole soldiers were not paid for their Civil War service and were denied pensions, despite promise of this recompense by the United States I highly recommend this book its extensive research is well documented It s clearly written It tells a very important part of the black history of the United States, and in particular a history of Florida, a history of Oklahoma, a history of the Civil War, a history of a resilient, proud, strong, intelligent people.Those of you who ve read The Speed of Life, an Illustrated Novel know about the principal characters who are part black, part Seminole My preparatory research for The Speed of Life included reading a lot of history as well as a lot of travel and personal investigation Wanting my characters to have verisimilitude, I had to know their history The Black Seminoles was one of the interesting books I read as part of that research. I read these books because I like to think I m smarter than I really am, and it gives me tidbits of knowledge I use at parties to woo the ladies ofyouknowwhatimean.So, I ve read most of them out there This, by far, is my favorite It boils it down so that a former infantryman like myself can make sense of all the big words without turining it into a coloring book simplification of particle physics.I ve bought it four times already because I keep giving them away to people.I d give it six stars if I could. This is a book about exploration in particular, the exploration of stars, how they can form black holes, and what happens at black holes It will perhaps be best appreciated by those who have at least some high school and preferably, undergraduate background in math and physics hence my not for complete dummies review title.The closest book that comes to mind is Voyages of Delusion The Quest for the Northwest Passage Glyn Williams, 2002 Both books describe the efforts of explorers to discover new realms, and thus make for fascinating real life is better than fiction tales of adventure But Black Holes and Time Warps is much it is a book about the physical universe that actually exists, but which we are incapable of experiencing on a personal level It strikes just the right balance of history and science, without becoming just another lame attempt to describe complex physical concepts to laypersons without any background in math or science.This book is also a grand tour of 20th century physics, not unlike a Rick Steves tour of Europe That is, not an exhaustive guide, but rather presented in a way that someone with a bit of scientific background can easily follow the development of the relevant subject matter If one wants an in depth version of the subject of 20th century physics, then I recommend The Road to Reality Roger Penrose, 2004 , but be prepared for quite a bit of math Start with Black Holes and Time Warps if that gets you hooked, then try Penrose This book is exceptionally well written, and the text is accompanied by excellent diagrams which help to explain the subject matter The author makes frequent cross references to other parts of the book to ensure that the reader can follow the narrative and the science in a seamless manner If you are interested in this subject, this is an excellent place to start your journey.I only wish that there were a 25th Anniversary Edition of this book, incorporating some of what has been discovered about black holes and other related topics since this book was first published way back in 1994 As but one example, the discovery in 2015 of gravitational waves by the LIGO detector, in which the author was critically involved see Ch 10 Such an update could easily be accomplished by the addition of a Recent Discoveries chapter, without having to fundamentally alter the underlying primary text other than perhaps an occasional footnote to the effect of, but see Ch 15 for recent developments on this subject. I picked this book out of my library and said I really need to read this book I know of Kip Thornes name and saw him on a video clip I have started reading this and it is written starting out as if you were assigned to explore these real entities called black holes He tells the story of what you would do as an explorer like a Star Trek show He makes you realize in your imagination what that creature looks like and describes it as if you were listening to him right there with you He even explains in very easy to understand concepts what powers of 10 means Diagrams of freq spectrum drawn out Different sizes of black holes and what that means as far as space time is concerned.This book was published in 1994 and I wish I had started reading it then Kip is 20 years ahead of his time And as a writer, he can talk you through this at a level of understanding of black holes with what we re dealing with I will be back for input as this is a keeper and will read it front to back.
