The authors brought together materials from mathematical competitions, books, research papers, discussions, and their own work. Such mathematical substance went far beyond the purposes of a traditional problem-solving book. The most attractive results refused to fit into the schemes of an instruction manual meant to exemplify typical problem solving techniques. A broader interpretation of these problems had to be identified, and this book is the fruit of that effort. Savchev and Andreescu detach certain statements or groups of related statements into independent sections. Treating these gems separately, in self-contained essays, emphasizes the source of their natural charm---connections with genuine mathematical experience. The essays are of impressive diversity, enlivened by fresh and original ideas. They involve concepts not only useful but also beautiful and nonstandard, with lots of esthetic appeal. The book is thus not so much a mathematical toolchest: it is an anthology of mathematical verse.Anneli Lax New Mathematical LibraryMathematicsProblems, exercises, etcProblem solvingMathematicsProblem solving.510Savchev Svetoslav1831373Andreescu Titu1956-285837Mathematical Association of America,MiAaPQMiAaPQMiAaPQBOOK9910963942603321Mathematical miniatures4403609UNINA02708ngm 2200529Ia 450 991073608590332120120926151047.0(CKB)5280000000117313(FOD)32726(FOD)100032726(OCoLC)709668573(EXLCZ)99528000000011731332725sInfobase32726Infobase20110207d2005|||| ||| vengurcnannnuuuuucrdamediacrrdacarrierInfection history /National Geographic Television & FilmNew York, N.Y.

Filmed at locations worldwide, the video traces the battles fought against humanity's oldest foes: diseases such as yellow fever, malaria, syphilis, cholera, smallpox, tuberculosis, polio, and perhaps the deadliest pandemic of all, AIDS. Health workers and epidemiologists on the front lines discuss the dynamics of combating disease, particularly in Africa, where AIDS ravages the continent. The growing problem of antibiotic resistance is also examined. Experts include Dr. David Ho, a virologist at the Pasteur Institute in Paris who has developed some of the most effective HIV drugs.Kill or cure.HistoryCommunicable diseasesDiseasesInfectionMedical microbiologySelf-care, HealthEducational films.Internet videos.Videorecording.localCommunicable diseases.Diseases.Infection.Medical microbiology.Self-care, Health.Films for the Humanities & Sciences (Firm)National Geographic Television & Film.AzPhAEMVIDEO9910736085903321Infection1930176UNINA
