الانفجار الأعظم

by James E. Lidsey, جيمس إ. ليدسي, عزت عامر (Translator)

Physics is usually thought of as the "hardest" science--but that really means it's the easiest. Physics is about broad generalities, not billions of specific cases. And astrophysics is about the true universals, those principles ("laws") that operate here and to the edge of the universe, now and since the beginning of time.

James Lidsey, an astrophysicist at the University of London, shows that it's possible to write a clear summary of the current thinking in his field in fewer than 150 pages. The Bigger Bang is a cosmology textbook for the intelligent layperson. Lidsey guides his readers through all the most interesting basics: relativity, where the chemical elements come from, superstring theory, the big bang, inflation, black holes. He writes in a lucid, rather British style that doesn't talk down to his readers, avoiding both excessive math and excessive metaphors. While Brian Greene's The Elegant Universe gives a good feeling for the personalities and vagaries of science, for the excitement and uncertainty at the leading edge, The Bigger Bang is a very clear, straightforward guide to the universe as we think we know it now. --Mary Ellen Curtin

ความหนาแค่ร้อยกว่าหน้า ผู้เขียนบรรยายภาพรวมของจักรวาลวิทยาไว้อย่างยอดเยี่ยม โดยเฉพาะเหตุการณ์ในช่วงต้นเอกภพ

I learned a lot about the primordial eras of our universe and the physics involved from this slim book, but the book felt uneven.

It seems like Professor Lidsey made a conscious effort to explain many of the concepts covered by the book through analogy. I got the feeling that perhaps this is how he lectures to undergraduates. Some of the analogies were apt and Lidsey explained them well. Others seemed ill-fitting and received very little explanation.

The early part of the book seemed to go too slowly for me. I thought I might recommend it for readers who are even less familiar with basic physics and astronomy than I am. Later, I felt like the author was leaving me behind. Toward the end, the pace seemed just right.

I couldn't discern a narrative flow in the book. I was often surprised from chapter to chapter (and sometimes page to page) where the author was headed.

On the Skip It/Borrow It/Buy It scale, I give this a solid "Borrow It".

وافي شامل ملم ، مكرر في بعض أجزائه ، يصادر علي المطلوب في مسائل قليلة .. و لكن إجمالا جيد إلي حد بعيد

[Som Banerjee · Rating 5 out of 5]

A wonderful book, let's you think so much and simplifies very tough ideas: I like those with the diagrams and summary like:

"the global universe consists of a network of baby universes that are generated inside black holes. These baby universes inflate, thereby producing more black holes and more baby universes. The quantum evaporation of the black holes allows the baby universes to separate from one another and our universe may have been created this way. In principle, this process can be repeated indefinitely."

So much is said in a such great summaries. So, if you are impatient reader then just reading those summaries itself will give you some idea.

Other very interesting idea I found in this paragraph:

"In this scenario, our universe was created when the space inside a newly formed black hole began to inflate. This implies that we could be occupying the inside of a black hole at present time......This opens up the possibility that we may be able to investigate what lies inside a black hole simply by studying the structure of our own universe"
