Few figures loom as large as Albert Einstein in our contemporary culture. It is truly remarkable that a man from such humble beginnings, an unemployed dreamer without a future or a job, who was written off by his professors as a hopeless loser, could to dare to scale the heights he reached. In this enlightening book Michio Kaku reasseses Einstein's work by centering on his three great theories - special relativity, general relativity and the Unified Field Theory. The first yielded the equation E =mc which is now such a fixture in our culture that it is practically a ubiquitous slogan. But the subsequent theories led to the Big Bang theory and have changed irrevocably the way we perceive time and space. Michio Kaku gives a new, refreshing look at the pioneering work of Einstein, giving a more accurate portrayal of his enduring legacy than previous biographies. As today's advanced physicists continue their intense search to fulfill Einstein's most cherished dream, a 'theory of everything', he is recognised as a prophet who set the agenda for modern physics.… (mer)

Very interesting review of Einstein's life and his effect on the world of physics and other fields.

Side Note: He had an open solar plexus chakra from an early age, in my estimation, which led to his youthful renunciation of his German citizenship and his cavalier approach to achieving his goals. I think it served him well. ( )

En El universo de Einstein, Michio Kaku, un físico teórico innovador y autor del “best seller” Hiperespacio, entrelaza la vida y la obra de Einstein con el fin de poder ver el universo tal y como lo veía Einstein, brindando una mirada privilegiada a su manera de pensar. Aunque sus teorías tuvieron enormes repercusiones, Einstein pensaba realmente en términos de simples imágenes físicas &―trenes a gran velocidad, ascensores cayendo, cohetes, relojes en movimiento&―. En realidad, fue a partir de dos de esas ideas simples como surgió el papel crucial de la relatividad en el movimiento del universo. La primera idea ocupó el pensamiento de Einstein desde que tenía dieciséis años, cuando intentaba imaginar cómo se vería un rayo de luz si corriera a su lado. La paradoja de una onda de luz en reposo le habría conducido finalmente a la relatividad y a E = mc2, la famosa ecuación que ha desentrañado los secretos de las estrellas. Einstein dio con su segunda idea mientras estaba reclinado en su silla en la oficina de patentes de Berna: ¿Qué pasaría –se preguntó- si él y su silla se cayeran? Esta imagen casi cómica le llevó a la idea de que la estructura del espacio y el tiempo es curva, desbancando a la misteriosa “fuerza” gravitacional de Newton. Esta idea, a su vez, nos ha permitido llegar a los agujeros negros y el Big Bang. La lucha infructuosa de Einstein por unificar todas las leyes de la naturaleza procede de su fracaso en dar con una tercera idea. Pero Kaku nos muestra de forma persuasiva cuántas ideas de Einstein de los últimos años de su carrera, anteriormente rechazadas por irrelevantes para la física, han llegado a fructificar en nuevos campos de investigación científica, nuevas tecnologías y varios premios Nobel. Sin olvidar que el espíritu de su búsqueda sigue vivo en la teoría de las cuerdas, protagonista de la física teórica más actual. Einstein sigue siendo uno de los más grandes y más estimados científicos de todos los tiempos, pero su trabajo y su legado han sido frecuentemente malinterpretados. Gracias a la perspicacia de Kaku y su habilidad para explicar en lenguaje llano los conceptos científicos más densos, El universo de Einstein proporciona una forma nueva y estimulante de apreciar la vida y las ideas de Einstein. Traducción de Víctor Zabalza de Torres.

Summary: This book was a mixture between an abbreviated biography of Albert Einstein and a discussion of how he came up with his theories. It is pretty good at explaining any physics that it included in the book, and was not at all difficult to understand for a complete layperson on the subject.

My Thoughts: I enjoyed this book quite a bit. It’s my second book by Kaku, and I plan on reading more of his work. His science is quite approachable and he keeps to interesting topics. ( )

Einstein was probably the greatest mind of the twentieth century, revolutionized physics, and his work is still producing new breakthroughs today. Michio Kaku recounts both his scientific contributions and something of his personal life in a completely engaging, entertaining way.

While Einstein was late in starting to talk, it's not true that he was a poor student in school. What he was, was a stubborn student. He had no interest in rote learning, which was the accepted pedagogic technique in Germany at the time. He would read, and think, and ask questions--and that mainly in the subjects he cared about.

Einstein's work on special relativity and general relativity changed our understanding of the universe and how it works. His struggles with quantum mechanics and his unsuccessful effort to create a unified field theory, a "theory of everything," have led some to say it would have been better for his reputation if he had not practiced physics for his last thirty years. Yet now, in the first decades of the twenty-first century, with advances in the technology available to study and test ideas, Einstein's work in the hands of a new generation of physicists and mathematicians is bearing new scientific fruit.

This is a fun, enjoyable read or listen, as well as educational.

Recommended.

I received a free copy of this audiobook from Audible in exchange for an honest review. ( )
