Summary
Jedno równanie unifikujące wszystkie oddziaływania i opisujące każde zjawisko - od ruchu rozszerzającego się Wszechświata po najmisterniejszy taniec cząstek subatomowych - taki cel stawiają przed sobą najwięksi fizycy na świecie。 Byłoby to ukoronowanie całego dorobku nauki， prawdziwy Święty Graal fizyki - jeden wzór， z którego można byłoby wyprowadzić wszystkie pozostałe równania。 Jest to wizja tak wspaniała， że zapiera człowiekowi dech w piersiach。
Wielu już próbowało zmierzyć się z tym wyzwaniem i poniosło porażkę， jednak Michio Kaku ma poczucie， że poszukiwania podążają wreszcie we właściwym kierunku， a najlepszą kandydatką na teorię wszystkiego jest teoria strun。 Wszechświat jest jego zdaniem symfonią， a myśli Boga， które tak bardzo pragnęli poznać Albert Einstein i Stephen Hawking， to kosmiczna muzyka wypełniająca całą czasoprzestrzeń。

Kaku is a strong and entertaining writer。 I liked the first half of the book which sketches the search for unifying theories。 The second major part of the book focuses on string theory in specific; I didn't come away feeling convinced that string theory is an exciting topic to learn more about。 Kaku is a strong and entertaining writer。 I liked the first half of the book which sketches the search for unifying theories。 The second major part of the book focuses on string theory in specific; I didn't come away feeling convinced that string theory is an exciting topic to learn more about。 。。。more

Michio Kaku has tried to present a summary of the development of theoretical physics’ theories since the early beginnings of the discipline in this book。He started by showing all the hard work done by scientists on the ancient dream of unification of physics’ forces and continued with the quantum revolution。 Subsequently， string theory and the theory of everything is looked at with a view on dark energy and dark matter。There is also an interesting philosophical dimension especially to finding a Michio Kaku has tried to present a summary of the development of theoretical physics’ theories since the early beginnings of the discipline in this book。He started by showing all the hard work done by scientists on the ancient dream of unification of physics’ forces and continued with the quantum revolution。 Subsequently， string theory and the theory of everything is looked at with a view on dark energy and dark matter。There is also an interesting philosophical dimension especially to finding a meaning to the universe and life。 。。。more

Huge fan of Dr Kaku; when I saw his new book I dropped my other reading for it。 Grateful I've read several Kaku books before。 This book felt more like a refresher。 I'm not a scientist and do not have a strong grasp on the concepts he specializes in。 Which is exactly why I am a fan！ He explains the most complex and fascinating things in a way I understand。 Now， this book didn't do that for me。 It's shorter than the others I've read by him。 And I found that detrimental。 I had to read many of the s Huge fan of Dr Kaku; when I saw his new book I dropped my other reading for it。 Grateful I've read several Kaku books before。 This book felt more like a refresher。 I'm not a scientist and do not have a strong grasp on the concepts he specializes in。 Which is exactly why I am a fan！ He explains the most complex and fascinating things in a way I understand。 Now， this book didn't do that for me。 It's shorter than the others I've read by him。 And I found that detrimental。 I had to read many of the sections multiple times to let them sink in。 If you are comfortable with the subject matter， then you wont have this issue。 Glad I read it， but didn't walk away from the book feeling smarter （which I did with his earlier work）。 I will say I loved the last chapter。 That was fun and fascinating！ 。。。more

This book is beautifully written and accessible for the lay person， but I still found it a bit of a slog until I decided to stop trying to hard to really understand the physics and treat it as if it were a Neil Gaiman book。 Then it became a page-turner and I think I actually do understand physics a bit better now。 Definitely recommend。It took me 3 months， not because the book was difficult， but because I kept adding other books to my current reading。 If one is good， why not have three or four go This book is beautifully written and accessible for the lay person， but I still found it a bit of a slog until I decided to stop trying to hard to really understand the physics and treat it as if it were a Neil Gaiman book。 Then it became a page-turner and I think I actually do understand physics a bit better now。 Definitely recommend。It took me 3 months， not because the book was difficult， but because I kept adding other books to my current reading。 If one is good， why not have three or four going？？？ :-） 。。。more

علمِ فیزیک در قرنِ نوزدهم دو ستونِ اصلی داشت: قانونِ گرانشِ نیوتون و معادلاتِ نورِ مکسول。 در قرنِ بیستم، اینشتین پی برد که قواعدِ این دو ستون با یکدیگر سازگار نیستند و یکی از آنها باید فرو بریزد。 فرو ریزشِ مکانیکِ نیوتونی موجبِ تحولاتِ علمیِ بزرگی در قرنِ بیستم شد。 پس از آن علمِ فیزیک دارای دو ستونِ اصلی شد: نظریهی گرانشِ اینشتین و نظریه ریز-اتمهای کوانتوم。 توسطِ نظریه گرانشِ اینشتین توانستیم تحلیلهای قابلِ اتکاتری دربارهی وجودِ سیاهچالهها، پدیدهی مهبانگ، و انبساطِ جهان داشته باشیم。 ال علمِ فیزیک در قرنِ نوزدهم دو ستونِ اصلی داشت: قانونِ گرانشِ نیوتون و معادلاتِ نورِ مکسول。 در قرنِ بیستم، اینشتین پی برد که قواعدِ این دو ستون با یکدیگر سازگار نیستند و یکی از آنها باید فرو بریزد。 فرو ریزشِ مکانیکِ نیوتونی موجبِ تحولاتِ علمیِ بزرگی در قرنِ بیستم شد。 پس از آن علمِ فیزیک دارای دو ستونِ اصلی شد: نظریهی گرانشِ اینشتین و نظریه ریز-اتمهای کوانتوم。 توسطِ نظریه گرانشِ اینشتین توانستیم تحلیلهای قابلِ اتکاتری دربارهی وجودِ سیاهچالهها، پدیدهی مهبانگ، و انبساطِ جهان داشته باشیم。 البته این دو ستون نیز با یکدیگر سازگار نیستند زیرا توسط اصولِ محاسباتی و فلسفهای متفاوت بنا شدهاند。 اکنون، تلاش ایناست که میان این دو ستون سازگاری و وحدت ایجاد شود。 [117] ما نظریههایی که در ابعادی بیشتر از سه بُعد بیان شده باشند را نادیده میگیریم چون خودمان در سه بُعد زندگی میکنیم: جلو وعقب، طرفین، بالا و پایین。 اگر بُعدِ زمان را نیز به آن بیافزاییم آنگاه میتوان گفت ما در جهانی چهار بُعدی زندگی میکنیم。 مثلاً تصور کنید که میخواهید نشانیای را توصیف کنید، میگویید: لطفاً حرکت کنید به طرفِ بولوارِ فلان （جلو یا عقب）، خیابانِ بهمان （طرفین/چپ یا راست）، طبقهی فلان （بالا و پایین）، ساعتِ فلان （زمان）。 در واقع ابعادی بیشتر از این چهار بُعد برای مغزِ ما قابلِ تصور نیست، به همین علت در نظریاتی مانند نظریهی ریسمان که قواعدِ آن در ابعادی بیشتر از چهار بُعد بهوقوع میپیوندند از ریاضیاتِ محض استفاده میشود。 [119] چرا ما میتوانیم فقط بخشی از طیفهای امواجِ الکترومغناطیس （رنگهای） را ببینیم؟ چون طولِ موجِ امواجِ الکترومغناطیس تقریباً به اندازهی طولِ آنتنی است که آنها را تولید میکند。 یعنی یاختههای شبکهی چشم ما فقط میتوانند طولِ موجِ رنگهایی را ببینند که تقریباً هم اندازهی آنها باشند。 به عبارتِ دیگر، ما فقط میتوانیم رنگهایی را ببینیم که طولِ موجشان به اندازهی ابعادِ یاختههای شبکیهی چشم ما باشد。 اگر یاختههای چشمِ ما به اندازهی یک خانهی معمولی میبودند، ما قادر بودیم همهی تابشهای رادیویی و مایکرووِیو （فروسرخ یا موجِ بلند） در اطرافمان را ببینیم؛ از آن طرف، اگر ابعاد یاختههای چشممان به اندازهی ابعادِ یک اتم میبودند، ما میتوانستیم پرتوهای ایکس （فرا بنفش یا موجِ کوتاه） را ببینیم。 [29] [یاخته کوچکترین واحد سازنده هر ارگانیسم است که میتواند تمام عملکردهای حیاتی را انجام دهد]。 نظریاتِ نیوتون و مکسول دربارهی سرعتِ حرکت اجسام و نور، نامفهوم ترجمه/توصیف شده است。 اینشتین از خود پرسید: چه نتیجهای از معادلاتِ مکسول میتوان گرفت اگر که بتوانیم با سرعتِ نور حرکت کنیم؟ [34]اگر فضا و زمان میتوانند تغییر کنند، باقی ابعادی که قابلِ اندازهگیری هستند مانندِ جرم و انرژی نیز میتوانند و باید تغییر کنند。 ما هرچه سریعتر حرکت کنیم، سنگینتر میشویم چون مقداری از انرژیِ حرکتیِ ما به جرم تبدیل میشود。 [35] اینشتین معتقد است جاذبهی گرانشی یک توهم است。 اجسام حرکت میکنند چون فضای اطرافِ آنها به علتِ وجودِ اجسامِ بزرگ و کوچکترِ دیگر دچارِ خمشدگی میشود؛ پس، این نیرویی تحتِ عنوانِ گرانش نیست بلکه خمشدگیِ فضا است که اشیاء را پَس و پیش میبرد。 [40] اجسامِ سنگینتر فضا-زمان را دچارِ خمشدگی میکنند و اینگونه توهمِ وجودِ نیرویی کِشنده و حرکتدهنده （گرانش） را ایجاد میکنند。 [42]نیوتون و اینشتین دارای تمرکزِ ذهنیِ فوقالعاده بالایی بودند。 وقتیکه دربارهی موضوعی میاندیشیدند حتا روی خوردن و خوابیدنشان اثر میگذاشت。 [45] هر دوی آنها قدرتِ بالایی در تصویرسازیِ ذهنی و نمودارپردازی （مربعها و مثلثها） و شکلسازی （قطارها و ساعتها） داشتند。 [46]شتابدهندهی ذرا ت آنقدر ذراتی مانند پروتون را در جهتهای مخالف شتاب میدهند که به انرژیای فوقالعاده بالا برسند، سپس آنها را به یکدیگر میکوبند تا آبشاری از ذراتِ زیر-اتمی خلق شود که بتوان آنها را توسط اَبَر کامپوترها مطالعه کرد。 یکی از اهدافِ این کار بررسی جهان در اندک زمانی پس ار مهبانگ است。 [87]اگر کتابی را بسوزانیم و یا در یک سیاهچاله بیاندازیم، آیا اطلاعاتِ موجود در این کتاب برای همیشه از بین میرود؟ مکانیکِ کوانتومی میگوید این اطلاعات هرگز از بین نمیرود زیرا با تجزیه و تحلیلِ یک به یکِ مولوکولهای کتاب میتوان کلِ آنرا بازسازی کرد。 [98] هنگامی که یک ستاره از ما دور میشود طولِ موجِ نورِ آن طولانیتر （قرمزتر） میشود، اما اگر به ما نزدیکتر شود این طولِ موج کوتاهتر （آبیتر） میشود。 اینگونه میتوان حدس زد که جهانِ اطرافمان در حالِ انبساط یا انقباظ است。 [108] 。。。more

This review has been hidden because it contains spoilers。 To view it， click here。 I wish I could give this a zero star rating。。。haha。 this is a fairy tale for grown ups。 Although it is a simple read， that is that even someone without a physics degree can understand it。 It is utterly ridiculous to postulate that by making an equation work on paper that somehow it makes it reality。 Kaku even admits that the Standard Model only works because the infinite possibilities are made to cancel out by much effort in the equations for the symmetry between the three forces involved （elect I wish I could give this a zero star rating。。。haha。 this is a fairy tale for grown ups。 Although it is a simple read， that is that even someone without a physics degree can understand it。 It is utterly ridiculous to postulate that by making an equation work on paper that somehow it makes it reality。 Kaku even admits that the Standard Model only works because the infinite possibilities are made to cancel out by much effort in the equations for the symmetry between the three forces involved （electromagnetic， strong nuclear， and weak nuclear）。 When speaking about the symmetry of the universe， specifically of the strength of the strong nuclear force and the weakness of the weak nuclear force he relegates that astronomical symmetry to generations that have yet to appear figuring out the final string theory equation。 He gets around the symmetry of the universe by saying people who aren't born yet will figure it out。 Reminds me of the Dawkins Debacle known as the god delusion。 Where Dawkins says he doesn't believe in God because of the anthropic principle。 And that the conditions of the Big Bang will be found out by future generations。 How is this scientific at all？ How is it scientific to assume that everything can be fit into a particle （quantum theory） and run through the quantum realm？ Notice that if you can't have something in the quantum realm （make it a particle。。。the higgs boson， the quark， the gluon， and now the inflaton。。。。） then you can't use mathematics because mathematics can only be applied to quantities that is quantities of particles。。。。！！！！！！ That's a pretty important distinction。 He then tries to close the book making the argument for his ridiculous position of agnosticism。 This is what happens when jokers make a god out of their brain and refuse to believe the truth of the King James Bible。。。they （Kaku included） will have to answer to God one day as to why they refused to believe 'In the beginning God created the heaven and the earth。 ' Gen 1:1。 。。。more

Just published on April 6， Professor Kaku’s latest book should be subtitled “A History of Physics from Pythagoras to Penzias and Beyond。” An easy weekend read， this 215 page paperback updates you on String theory， M Theory， and the history behind modern Cosmology and Quantum Theory。 Accessible even by middle schoolers interested in science and with a little background in modern physics and a strong interest in space and time。 Should be on every high schoolers summer reading list。
