risks can he ~ ade l e ss than l1is c.1.lculat ions show if monitoring precaustions, concentration of burial and other procedures (currently- being employed) are taken into account. Cohen concludes tha t nuclear energy is far safer than most of the current ~ethods of producing energy. n fact, nuclear power processes in the long run nay save lives, as a result of burying l ong- lived radioactive elements: surely a point worth considering is looking for new s ources of energy. ************************************************************************************************* Evolution of P,ed Giant S tars A su~mary is made by Allen V. Sweigart in the January 1976 issu of Physics Today on the evolution of red giant stars, The summar; i s mad e within the general franework of uniformitarian astrononical evolution, and is of interest in understanding what is currently being considered in the evolutionary framework. The summary spe cifies how s u e~ r e d stars 11 evolve 11 by successive processes of hydrogen fusion into helium (a process similar to that of t he hydrogen borr.b), and then later (a core temperature increases) the fusio~ of helium into carbon and oxyge n eventually nitrogen. Still later (as core te~peratures receive further), the r.itrogen picks up two helium nuclei to become Neon, which i-q turn absorbs an alpha particle to become magnesium. The author then describes various convectional i ns tabiliti es t hat ci~h t occur in the s t ar, which woul d bring the heavier e lereents from t he core to t he s t ar surface, thus pe r mittin? us t o see the spec t ral lines correspondin g to such ele ~e nt s. The - author went i ons tha t t he mode l does (at least qualitatively ) explain the pres cence of heavie r e l enents with spectra of l a r ge m3s S s t a r s. but un fortunately does not explain t he pres cence o f s uch elements in lao;..' mass stars. After the aut hor point s ou t,,.this i s t he e:-:istence o f s uch questions. however. t hat makes the subject of red- gi ant e~olu tion an active a rea of r esearch. " Once a gain we are treated t0 the spectacle of seeing a scientist unwilling to eve n question the basic premise o f star evol u tion, but r a ther to a ccep t i t and gear one ' s search to ''solving an unresolved proble m~~ in t he evolution of stars. 2

Answer to Last ~onth's Puzzle The procedure is to determine the weight of each block in terms of marbles, as a basic unit. 12 unit~= 1 top + 3 blocks 8 units + 1 block = 1 top Therefore, 12 units ~ (8 units+ 1 block) + 3 blocks, Hence, 4 blocks+ 4 units, and 1 block~ 1 unit. Therefore, 1 top- 9 units (marbles). ************************************************************* This Honth's Puzzle A man enters a hardware store and Rreets the clerk. "How much is one? The clerk responds, "Twenty cents." "Ho\J much 11 is twelve?" The ansy.~er, ''Forty cents. 11 "Fine, 11 answers the man, "1'.11 take two hundred. " "OK.," says the clerk, "that 1 ll be sixty cents." h~at is the man buying?
