On Albert Einstein's seventy-sixth and final birthday, a friend gave him a simple toy made from a broomstick, a brass ball attached to a length of string, and a weak spring. Einstein was delighted: the toy worked on a principle he had conceived fifty years earlier when he was working on his revolutionary theory of gravity--a principle whose implications are still confounding physicists today. Starting with this winning anecdote, Anthony Zee begins his animated discussion of phenomena ranging from the emergence of galaxies to the curvature of space-time, evidence for the existence of gravity waves, and the shape of the universe in the first nanoseconds of creation and today. Making complex ideas accessible without oversimplifying, Zee leads the reader through the implications of Einstein's theory and its influence on modern physics. His playful and lucid style conveys the excitement of some of the latest developments in physics, and his new Afterword brings things even further up-to-date.
作者從愛因斯坦的一個玩具開始,先講牛頓如何發現萬有引力,然後講愛因斯坦的觀點,在所有這些敘述過程,不是用理論和公式來說明,而是生動形象的比喻和想象,而這些比喻和想象都非常直觀明瞭,再加上文筆詼諧,一如作者所推崇的阿西莫夫的風格,讓我這個雖然學過物理的人讀瞭...

評分宇宙的樣子類似於一個氣球,她可以變大還可以變小。當她變大時,宇宙就膨脹,因此宇宙中的物質就會分開,因此我們就將這種現象稱為宇宙膨脹現象,她的原因是宇宙在初期的暴漲和開始的爆炸,這是奇怪的,並且是有矛盾的,所以我們並不能證明這個結論。 在早期宇宙不是一個惟...
