Chi possiede il passato? Come si leggono le ossa antiche? E cosa ci dicono sulle nostre origini gli artifatti, il polline e il DNA dell’età glaciale? Usando tecniche sempre più raffinate, gli scienziati riescono a ricostruire gli ambienti del passato profondo e i primi esseri umani che ci vivevano. I lettori di ossa esamina i fatti e i miti sull’arrivo dei primi uomini in Australia; il DNA degli attuali Aborigeni australiani rivela le loro origini; le teorie degli hobbit indonesiani; e chi o cosa ha ucciso i marsupiali giganti dell’Australia. Le scoperte australiane trovano eco nei dibattiti sulla misteriosa fine dei Neanderthal e gettano luce sull’evoluzione umana. Ma, come sempre, gli scienziati sono divisi. I lettori di ossa mette in evidenza un mondo di coloriti personaggi e un dibattito appassionato – e alcune idee veramente bizzarre. Questo libro chiarisce le idee a chi è incuriosito da affermazioni e contro-affermazioni su chi ha fatto cosa, quando a e a chi nel profondo passato della preistoria e spiega in modo lineare la scienza su cui si basano le recenti metodologie investigative. Senza timore di essere controverso, I lettori di ossa è destinato a riscaldare il dibattito sul passato dell’umanità.

Il volume si propone lo scopo di fornire al lettore i concetti fisici fondamentali che stanno alla base della spettroscopia atomica e dei processi di emissione e assorbimento della radiazione nei plasmi di laboratorio e astrofisici, coprendo argomenti fondamentali quali gli spettri atomici di atomi a uno o più elettroni, la quantizzazione del campo elettromagnetico, l'interazione fra materia e radiazione (trattata sia dal punto di vista classico che quantistico), le transizioni radiative, i fenomeni di equilibrio e non-equilibrio nei plasmi, la teoria del trasporto radiativo, l'emissione della radiazione di ciclotrone, di sincrotrone e di frenamento, e la diffusione Compton relativistica (trattata col formalismo della seconda quantizzazione). Il contenuto del volume e la sua impostazione generale, basata sui principi fisici, ne fanno un testo ideale per un insegnamento monografico semestrale, annuale o biennale (a seconda degli argomenti scelti) in un Corso di Laurea Specialistica o in una Scuola di Dottorato, nonché una buona base di riferimento per ricercatori attivi in varie discipline quali la Fisica Atomica, la Spettroscopia Ottica e UV, l'Astrofisica e la Fisica dello Spazio.
