{ "item_title" : "Causality Rules (Second Edition)", "item_author" : [" Vladimir Pascalutsa "], "item_description" : "Causality: Cause and effect. In classical physics, an effect cannot occur before its cause. In Einstein's theory of special relativity, causality means that an effect cannot occur from a cause that is not in the back (past) light cone of that event.The books cover the useful physical relations inferred by unitarity and causality. A famous example is the Kramers-Kronig relation for the refractive index of a gas or dilute medium. For example, in Chapter 3 generalises the Kramers-Kronig relation to relativistic medium, such as CMB (photon gas). These relations are extensively also used in particle and nuclear physics. Especially useful are the so-called sum rules, such as the Gerasimov-Drell-Hearn (GDH) or the Baldin sum rule.The author notes that the first edition is too brief. In his teaching practice, he sees that is is challenging to use as a standalone text. He intends to improve the explanations of many topics that students found particularly challenging. The additional material will make the book more timely, self-contained, and logically complete.Key Features: Modern book on a timely subject Classroom friendly and built on newly developed courses taught at a major Physics Department in Germany Advanced material written in simple non-technical language Includes pedagogical examples and discussions of the current forefront research ", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/0/75/033/429/0750334290_b.jpg", "price_data" : { "retail_price" : "190.00", "online_price" : "190.00", "our_price" : "190.00", "club_price" : "190.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
