Ehon - Thực Phẩm Tâm Hồn Cho Bé: Những Cuộc Phiêu Lưu Của Cậu Bé Pinocchio (Song Ngữ) Thư viện Sách hướng dẫn

Sách được viết bởi Bởi: Carlo Collodi

Brain (sic) Cox is one of the current pin-up boys of science; ex pop musician, he is now a physicist working at the LHC in Switzerland when he isn't gadding about the world for his latest TV series or recording The Infinite Monkey Cage for BBC Radio 4 (listen if you get the chance - it is brilliant). There are many explanatory books about the theories of Relativity, most of which are so up there own backsides that they are unreadable unless you have a degree in theoretical physics. Cox and Forshaw conquer by stooping low enough to make the subject intriguing, interesting and intelligible. Of all the equations known to man Einstein's final statement of the Special Theory of Relativity is probably the one that is best known to educated man. Ee equals emm see squared (and I apologise for altering the title, I can't get my computer to generate a squared symbol) generated a wholly different view of the universe to the one that had held sway since the time of Isaac Newton. The problem was that, as experimental physics became more precise, nice and accurate, the answers generated by Newtonian physics were not supported. The difference may have been in terms of more decimal places than Newton ever envisaged but there was a level of inconsistency that could not be ignored. As Richard Feynman said (paraphrased), "If the evidence doesn't fit the theory is wrong". The other equation most people remember is ascribed to Pythagoras; the square of the hypotenuse in a right angled triangle is equal to the sum of the squares of the other two sides. From this, via Newtonian laws of motion and electromagnetism Cox and Forshaw take us on a journey to explain how Einstein came to his conclusions and what their impact is on our understanding of the universe and (almost) everything within it. The steps taken are gentle, well explained and the mathematics is not particularly taxing. Physics, theoretical and experimental, has evolved over time as our abilities to investigate have improved; it is the downside to being a particularly clever monkey. Asking questions about how things work has been our curse, the ability to find some answers our blessing. We are now at the stage where we can force streams of particle to accelerate to near light speed, smash them together and analyse the results to see whether they match what has been predicted. This book is as much about the history of human thought and discovery as it is about mathematics. It is also about numbers that are so small or so large that they are mind boggling. It introduces that mathematics of spacetime in a way that arouses curiousity, rather than fear. Moreover it is a very honest book; it does not claim that Einstein's theories explain everything but that it produces a picture that is more accurate than the previous theories. Until the next one.

Độc Thân, Cần Yêu (Tái Bản 2014) Thư viện Sách hướng dẫn

Werewolves Rule! is the sequel to the super-fun YA Urban Fantasy Vampires Rule! As much as I enjoyed the first book, I still had issues regarding editing and other minor story quirks. In this book, there were no really noticeable editing mistakes and the story had an excellent flow. The hero, Jack is a former vampire who was returned to mortality and humanity in the first book. In this story we continue with Jack's path toward a final battle with the powerful Jersey Clifford, the world's first werewolf. Jack's roller-coaster relationship with his destined girlfriend, Silver, heats up (but not in a good way). Actually Jack finds it hard to stay in a good relationship with anyone, his girlfriend, his brother, his teachers... Several new characters are introduced and they make a big splash right away. Isobel, a werewolf, links Jack to his previous incarnation and tells him that they were lovers in a previous life. This can only end badly, right? Well, I won't give anything away here. However, this book brings all of the previously loose plot threads into sharp focus, ending some while unravelling others. The action and suspense are ratcheted up a few notches from book 1 as well. I thoroughly enjoyed every page of this story and hope that there will be a book 3 very, very soon! Oh, and the best line from the book? Jack's brother Billy says to him - "Why don't you sparkle?"
