Peter Olofsson – författare

Berättelserna spänner över olika genrer och stämningar: från det stillsamt psykologiska till det drastiskt dramatiska, från vardagsnära igenkänning till krypande obehag. Det handlar om återupprättelse och svek, skuld och försoning, livets små vändningar och dess stora avgöranden.

“If there is anything you want to know, or remind yourself, about probabilities, then look no further than this comprehensive, yet wittily written and enjoyable, compendium of how to apply probability calculations in real-world situations.” — Keith Devlin, Stanford University, National Public Radio’s “Math Guy” and author of The Math Gene and The Math Instinct

“A delightful guide to the sometimes counterintuitive discipline of probability. Olofsson points out major ideas here, explains classic puzzles there, and everywhere makes free use of witty vignettes to instruct and amuse.” — John Allen Paulos, Temple University, author of Innumeracy and A Mathematician Reads the Newspaper

“Beautifully written, with fascinating examples and tidbits of information. Olofsson gently and persuasively shows us how to think clearly about the uncertainty that governs our lives.” — John Haigh, University of Sussex, author of Taking Chances: Winning with Probability

From probable improbabilities to regular irregularities, Probabilities: The Little Numbers That Rule Our Lives investigates the often-surprising effects of risk and chance in our everyday lives. With examples ranging from WWII espionage to the O. J. Simpson trial, from bridge to blackjack, from Julius Caesar to Jerry Seinfeld, the reader is taught how to think straight in a world of randomness and uncertainty. Throughout the book, readers learn:

Why it is not that surprising for someone to win the lottery twice How a faulty probability calculation forced an innocent woman to spend three years in prison How to place bets if you absolutely insist on gambling How a newspaper turned an opinion poll into one of the greatest election blunders in history

A mathematical and intuitive approach to probability, statistics, and stochastic processes

This textbook provides a unique, balanced approach to probability, statistics, and stochastic processes. Readers gain a solid foundation in all three fields that serves as a stepping stone to more advanced investigations into each area. This text combines a rigorous, calculus-based development of theory with a more intuitive approach that appeals to readers'' sense of reason and logic, an approach developed through the author''s many years of classroom experience.

The text begins with three chapters that develop probability theory and introduce the axioms of probability, random variables, and joint distributions. The next two chapters introduce limit theorems and simulation. Also included is a chapter on statistical inference with a section on Bayesian statistics, which is an important, though often neglected, topic for undergraduate-level texts. Markov chains in discrete and continuous time are also discussed within the book.

More than 400 examples are interspersed throughout the text to help illustrate concepts and theory and to assist the reader in developing an intuitive sense of the subject. Readers will find many of the examples to be both entertaining and thought provoking. This is also true for the carefully selected problems that appear at the end of each chapter.

This book is an excellent text for upper-level undergraduate courses. While many texts treat probability theory and statistical inference or probability theory and stochastic processes, this text enables students to become proficient in all three of these essential topics. For students in science and engineering who may take only one course in probability theory, mastering all three areas will better prepare them to collect, analyze, and characterize data in their chosen fields.

Pensionerade parkeringsvakten Linnea Oscarsson visste inte vad hon skulle tro. Ett efterlämnat skrin från en gammal släkting visar sig innehålla en brevväxling där Oscar II är inblandad. Och det ser ut som att det finns dyrbarheter att hämta. Men var? Hon tar sin unge vän Johan till hjälp för att lösa mysteriet. Det börjar med ett lyckat inköp av en begagnad dator men övergår snart i ond bråd död. Om hon ändå inte rört det där verktyget … När städerskan på Sveriges VVS-museum i Bromma finner en ihjälslagen man i samlingens plåtbadkar kopplas polisen in och kriminalinspektörerna Karin Orre och Lukas Rosenquist står inför ett mysterium som till sist inbegriper en vettskrämd kvinna och en libanesisk gangsterklan. Kjell E. Genberg har skrivit romaner i flera genrer sedan bokdebuten 1966. Han har arbetat som sjöman, dykarskötare, lotsbiträde, mudderverksarbetare, pråmskeppare, musiker, truckförare, journalist, popbandsmanager och tidningsutgivare. Peter Olofsson är chefredaktör för tidningen Energi & Miljö. Han har varit kommunikationschef inom flera stora företag och även arbetat som reklam- och tidningsmakare. Han har skrivit ”Spänning och ledning under hundra år” om elektricitetens utveckling i Sverige.

Kriminalinspektörerna Karin Orre och Lukas Rosenquist hämtar Linnea Oscarsson från kvinnofängelset Hinseberg. Året innan hade de sett till att hon hamnat där som ansvarig för en ung pojkes död. En vattenläcka i Linneas badrum blir upprinnelsen till intensiv kärlek, avancerad narkotikasmuggling, oväntad död – och upprörda känslor mellan en rörmokare och en elektriker. Vad är det som pågår på nybygget i Annedal i Bromma? Hur passar Templet i Gnesta in i bilden? Polisen utreder på hemmaplan. I Montenegro byggs en tidigare nazistisk kommandocentral om till ett lyxigt hotellkomplex. Men vad döljer sig i hotellets källare? Peter Olofsson är chefredaktör för tidningen Energi & Miljö.

Per Fleck blir en smula galen … och ett dussin andra skrönor från Lillesta är en samling på tretton berättelser som utspelar sig i en fiktiv svensk småort. Det handlar om människorna i utkanten av dramatiken: de som får vardagen att gå ihop medan verkligheten – ibland bokstavligen – skenar. Genom skrönans fria form förenas värme och satir, humor och allvar, och berättelser skapas där det lokala speglar något allmänmänskligt. Lillesta är en plats som inte finns, men som kunde ha legat var som helst. Här finns en gubbpanel på Centralkonditoriet, en själavårdande men svajig kyrkoherde, ett par överbelastade polisassistenter – och människor som på olika sätt konfronteras med det oväntade. I varje berättelse finns ett brott eller en kris, men också spår av försoning, eftertanke och skratt.

Det finns ett land som bara öppnar sig för den som minns hur det var att längta. Ett land av mörker och ljus, stillhet och rörelse, doften av gran och ljudet av steg i snö. Det landet heter Tomteland. Här möts åtta författare i nitton berättelser där julens glans blandas med skuggor. Medverkande författare: Peter Olofsson, Kjell E. Genberg, Britta Ivarsson Possnert, Richard Nordström, Ulf Durling, Ulf Broberg, Lena Köster och Karin Tjäder.
