This is a prospective submission to the Journal Scientific American or an affiliate, however I have decided to release it early for the interest of the public, since it is unlikely to be accepted. I still hope this paper is taken to be significant to science.
Fairly complete evidence of adequate principles, if Newtonian mechanics is taken into account.
To better understand the risk and safety of heading a soccer ball, the author created a set of simple mathematical models based upon Newton's second law of motion to describe the physics of heading. These models describe the player, the ball, the flight of the ball before impact, the motion of the head and ball during impact, and the effects of all of these upon the intensity and the duration of acceleration of the head. The calculated head accelerations were compared to those during presumably safe daily activities of jumping, dancing, and head nodding and also were related to established criteria for serious head injury from the motor vehicle crash literature.

With his latest thematic study of democratic Athens P. reassesses the argument, originally offered by Demosthenes and Plutarch and subsequently championed by A. Böckh, that the Classical Athenians were guilty of spending more on their theatrical spectacles than on their military exploits. Here, by assembling the fragmentary fifth-and fourth-century evidence and then judiciously deploying financial analyses, P. hopes to 'settle debates about public spending in classical Athens' and confirm 'the priorities that the Athenians set for their state' (p. xv). P.'s consideration of that diverse evidenceboth literary and epigraphic, and dating largely from the 420s, 370s and 330sallows him not merely to confirm (contra Böckh) that the military was far and away the Athenians' most expensive public undertaking, but also to develop a clear model of Athenian public expenditures that ancient historians will find useful both in its own right and as a catalyst for future study. Early in his introductory remarks P. sets forth a programmatic tricolon worthy of Lycurgus: 'The major public activities of the Athenian dêmos ("people") were the staging of religious festivals, the conducting of politics, and the waging of wars' (p. 1). The scholarly 'public spending debates' subsequently outlined by P. concern both the absolute and the relative levels of Athenian expenditures on such activities: was more money spent on festivals or on fighting? Was the money necessary for maintaining the democracy available domestically or only as a result of empire? Writing two centuries after Böckh and his Die Staatshaushaltung der Athener (1817) set the agenda for the modern study of Athenian finance, P. takes advantage of the additional sources at his disposal: beyond the hundreds of newly-uncovered Attic inscriptions and the text of the Aristotelian Constitution of the Athenians, he readily employs recent studies by scholars such as E. Csapo, W. Slater and P. Wilson detailing the financial as well as cultural contexts of (e.g.) the City Dionysia and the Athenian khoregia. Throughout this volume P. is scrupulous in his use of these primary and secondary sources: he readily acknowledges the conclusions reached by other scholars, the limitations of the ancient evidence and those occasions whenall too oftenhe must proceed more speculatively. Some more sceptical readers may be surprised by how adamant P. is about the dêmos' knowledge and control of Athenian finance; they will benefit from reading his arguments (pp. 16-24) and considering his cited sources, even if they still wonder exactly how well, and how often, Athenian practice followed theory. As the aforementioned tricolon suggests, the body of this volume models Athenian expenditures oni.e. provides 'costings' forfestivals (Chapter 2), democracy (Chapter 3) and war (Chapter 4). Of the remarkable number of festivals celebrated by the Athenians two were especially significant, culturally as well as financially: the annual City Dionysia and, every fourth year, the Great Panathenaia. Following in the footsteps of P. Wilson's (2008) costing of the City Dionysia (28 t. 5200 dr., with slightly more than half deriving from the baseline of private liturgical expenditures), P. begins by costing the Great Panathenaia. Drawing together the prize (c. 1,447 amphorae of sacred olive oil) and public and private liturgical contributions, P. reaches a total of 25 t. 1725 dr., oramortised over the four-year periodsome 6t. 1931 dr. annually. Ultimately P. reckons that these two festivals accounted for some 35% of Athenian festival THE CLASSICAL REVIEW
