Nothing travels faster than the speed of light, and light travels at one fixed speed. This idea is considered a foundation of modern physics, but what if it is wrong?Theoretical physicist Magueijo presents the idea that light traveled faster in the early universe than it does today. The varying speed of light theory solves some of the most intractable problems in cosmology ...more

خلصت الجزء الاول الخاص باهم النظريات اللي بتتناول طبيعة بنية الكون في علم الفيزياء والكونيات

وبدات الجزء التاني اللي بيبدأ يشرح فيه نظريته القائمة على تغير سرعة الضوء

حابب بس اسجل اهم النظريات اللي كانت قبل نظريته او نموذجه الكوني

قوة الجاذبية لنيوتن

النسبية الخاصة والعامة لأينشتاين

نماذج الكسندر فريدمان للكون وهم 3 نماذج اساسية

قياسات ادوين هابل ونظرية الانفجار الكبير

الكون الانفجاري التوسعي لآلن كوث

فيه طبعا نظريات تانية واجتهادات بين النقاط المفصلية دي لكني فضلت وضع عناوين كبيرة لاهم التطورات

If you want to know about Joao's idea VSL (variable Speed of Light) look elsewhere. If you want to know how bad Joao hates scientific administrators and editors, this is the book for you.

This is the worst book I have ever read. Actually, I could not even finish it and I was trying really hard because I had promised a friend I would read it. (Sorry, DC...)

The style in which this book is written makes me angry. What the author wants you to think when you buy or lend this book is that he is going to tell you about things in physics that he thinks marvelous. What the author really is telling you is how great he is, what a wonderful person, what a good physicist. And you... a reader.

يتناول الكاتب فى الجزء الاول تفسير النظرية النسبية لاينشتاين والتى تقوم على اساس ان سرعة الضوء ثابته ,كما انها الحد الكونى اى لا يمكن تجاوز سرعة الضوء
وفسر اينشتاين ذلك بان كلما زادت سرعة الجسم ,زادت كتلته وبالمثل تزيد القوة المطلوبة للتأثيرعليه
وعند زيادة السرعة لتقارب سرعة الضوء تحتاج الى قوة لا نهائية لتحريك الجسم
كما اضافت النظرية النسبية انًا نعيش فى كون رباعى الابعاد ,ساكن ,وتؤثر فيه الجاذبية والتى هى انحناءات الزمكان ,حيث يتميز الفضاء بانحناءات تجبر الاجرام السماوية على السير فى مسارات بي

بهذا الكتاب يطرح كاتبه قصة نظريته
و قد بذل مجهود كبير في تحويل ابحاثه و دراساته الى لغة يمكن لنا نحن غير المتخصصين ان نفهم العديد من جوانبها

جميل ترتيب الكتاب حيث بدأ بسرد شرح بسيط عن النسبية و نظرية الانفجار التوسعي ثم ذهب يسرد رحلته مع النظرية

وجدت صعوبة ببعض الفصول التي تتحدث عن الفيزياء ..لاني من اربع سنين لم ادخل عالم الفيزياء والكونيات و ليس لي ادنى معرفة فيها قبل ذلك

الكتاب اشعل فتيل جمال علم الفيزياء التي كنت لا احبها في ايام المدرسة

وجميل من الكاتب ان كتب عن المؤسسة التعليمية هناك و سلبياته

من أفضل الكتب العلمية محتوى وترجمة ..

ملخص سريع : يبدأ الكاتب بتقديم أحداث فيزيائية تظهر في تفسيراتها تناقضات داخلية ضمن الميكانيكا الكلاسيكية ( النيوتنية ) والكهرومغناطيسية ، ويقترح الحل لحلها وهو " النسبية الخاصة " ، ويسير بهذا الطريق في معالجة التعارض بين الأخيرة وقانون الجذب الكوني وصولا للنسبية العامة وحلولها والكون وفقا للنسبية العامة .

يدخل بعد ذلك في شرح معالم نظريته وتطورها مشوبة بكثير من التفاصيل عن الأحداث الشخصية والإجتماعية التي حدثت للكاتب ، ويسترسل في علاقتها بباقي النظريات المعاصرة

إن لم تستطع يوما أن تتخيل حياة عالم حقيقي في العمق ، فتخيلها هنا !
إن لم تستطع في يوم أن تفهم النسبيتان "الخاصة والعامة" ، فستفهمهما هنا !
وبكل تأكيد إن ظننت للحظة أن العلماء ملائكة ، فجرب حظك هنا !

Personal & Spiritual Journey of a Cosmologist in the Discovery of VSL Theory

This is a fascinating story of a young cosmologist who dared to challenge Einstein's most sacred laws of physics; the speed of light in vacuum is a universal constant. In human experience; space and time are perceived as universally rigid, but Einstein proposed that space & time; space-time could expand or contract but speed of light remains unchanged. On occasions many physicists have wondered, and debated that

هنالك من ليس لدية معلومات عن الفيزياء او علم الكون او لدية معلومات بسيطة جداً

Ok, so this book was extremely challenging, and, thus, I am extremely proud of myself for making it through the whole thing. The physics in this book was definitely difficult to comprehend fully. Going in, I hoped that because I am a generally science-minded person and took physics in college, it wouldn't be too bad. I'm sure if the subject matter had overlapped, that would have helped. However, this is definitely not general physics. It's not motion and forces and the arc of a thrown baseball. ...more

Ten years since this book literally fell into my hands, I continue to recommend and treasure it. Every now and then, I pick it up, open to a random page and enter the maze of inspirations Magueijo’s wit and wisdom drive me to explore. I’ve yet to find a science-focused book this entertaining, this enlivening to my own creativity. Read it to understand things you thought you already had the gist of — read it to go behind the curtain where “sweaty” thinking is both inanely tormented and lovingly p ...more

الكتاب يحكي عن نظرية جديدة ... هي "السرعة المتغيرة للضوء" وأثر ذلك على فهمنا للكون ...
راوي الكتاب هو صاحب النظرية ... يحكي عن بداية الفكرة وكيف تطورت, الصعوبات والنقد الذي تعرض ويتعرض له, محاولات النشر, النظم الأكاديمية الجافة التي ترفض الأفكار الجريئة, المساعدة التي وجدها في طريقه لتكوين النظرية ...

بشكل عام ...
النظرية لم يتم إثباتها بشكل قاطع ...

FASTER THAN THE SPEED OF LIGHT: The Story of a Scientific Speculation. (2003). Joao Magueijo. ****.
The author is a professor of theoretical physics at Imperial College, London, where he was for three years a Royal Society Research Fellow. He received his doctorate in Theoretical Physics at Cambridge University. He wrote this book to serve as a platform for the dissemination of his work on and belief in VSL. VSL stands for Variable Speed of Light, although to its detractors, it means, “Very Sill

This is Magueijo's telling of how he dared to challenge Einstein on the constancy of the speed of light and confront physics by introducing a new Varying Speed of Light (VSL) theory. This is like breaking one of the ten commandments of physics, and his perseverance in the name of science is admirable. The background and details of the theory aren't too mathy and are conveyed in a manner that makes them accessible to the average reader, I'd say (though, I do have a background in physics, so perha ...more

I love reading about advances in theoretical physics but it has to be a book by someone who can interpret this difficult and sometimes arcane subject for the layman. Joao Magueijo is such an author and he combines his training and research with great skill writing in a layman friendly way, and even combines a fair bit of insider stuff and humour about the world of theoretical physics.

In particular, he gives a nice overview of the problems and discoveries in theoretical physics from Newton unt

I'm not an expert on the subject but as an engineer I understand physics and mathematics behind it in general. I opted for engineering studies instead of physics which was my first choice because I had a feeling that physics seemed to be spinning in circles, as if it was overwhelmed by an infatuation for following the lead of equations, and that it does not relate to real world problems much nowadays. I might have been right or wrong, it is just my view. This book gave me another good insight in ...more

I was inspired to read FASTER THAN THE SPEED OF LIGHT after seeing a special on the Science Channel in which Joao Magueijo explained his theory about the speed of light not being constant. He developed the theory that light may have moved faster when the universe was created than it does now, as a way of explaining certain paradoxes about the "Big Bang" theory that have confounded cosmologists (scientists who study the origins of the universe--not to be confused with cosmetologists) for decades. ...more

Simpática introducción al trabajo de este físico portugués del que se escuchó mucho los últimos años. Además de divulgación científica (de su trabajo) también es un testimonio de las vicisitudes de un físico novel con ideas iconoclastas. Además de llamarnos “fauleros” cuando jugamos al fútbol los latinoamericanos :-) nos da un vistazo a las envidias, egoísmos y subterfugios al que el mundo de la ciencia no puede escapar.

عنوانه جذاب جدا وهذا ما دفعنى لشرائة

بالنسبة للفصل الأول فهو يعتبر مقدمة عن حياته وأن أزاى النظرية اللى بيطرحها أتعرض بسببها للسخرية فصل مكنش مهم أوى بالنسبالى.

بالنسبة للفصل التانى فهو مذهل بمعنى الكلمة كنت بقرا فقرة وأعد أتخيل اللى قاله ده، وقدرت بسببه أستوعب أجزاء كتير مكنتش فهمها فى نظرية النسبية وقدر يبسطها باكثر من مثال ومن كذا جانب

بالنسبة لباقى الفصول، التوهان كان عنوانى، الكتاب محتاج حد متخصص فى المجال عشان يعرف يفهم الكتاب كويس، فى أفكار كتير وقعت منى وأكيد هحتاج اقراه ما مرة

I did and I'm not sorry.


I'm on page 65. So far there are some good explanations of Einstein's special and general relativity that I haven't seen elsewhere, and I've probably read a lot more physics books than the average non-physicist.

Mainly an insider’s account of the politics of academia, this book describes the author’s struggle to develop and publish his varying speed of light theory (VSL) that, if correct, may explain two paradoxes that arise from the Big Bang theory, the “horizon” and “flatness” problems. The first half of the book provides an excellent foundational discussion of relativity, but second half fails to address VSL in any detailed way and instead deteriorates into an expletive-laced rant about the bureaucra ...more

The author was brutally honest and witty and intelligent and it's not just about scientific equations and physical laws (well, it it...) but when you close the book, it's as if you have witnessed a journey of the lives of people trying to find other answers and searching for new "truths" and "answers" to mysteries that has always puzzled the human mind.

A nice mixture of the history of cosmology, current developments, the process of science, and the author's personal life.

The first half of the book provides a nice, easy to follow overview of the theory of relativity, filled with cows moving at near the speed of light. Simple enough for the non-physics oriented to follow, without losing the essential details.

The second half outlines the development of the varying speed of light theory, focusing as much on the people involved as on the science. I

Faster Than the Speed of Light

A friend gave this to me as a birthday gift when I was in college. I had no idea what a great trip I was in for. He was a very entertaining story teller. This book surrounds his research into a train of thought that modifies the fundamental constructs of physics.

Although the concepts were advanced the author did a great job at keeping it simple enough for the average reader. A fantastic find!

Did I enjoy it? Yes!

Would I recommend it? Yes!

I know that some reviews said this was more about him bitching about the establishment than about physics.....and it's sort of true.

At the same time, however, I found the entire thing engaging from start to finish (only took me 3 days). I found his raving to be humorous, and not in a "I'm laughing at him" way.

All that being said, I'm happy to say that I've learned more of modern physics from this book than I have in the past 2 books I've read combined. I just wish he was more of a string theory
