  • Pythagoras af Mads Dahlgaard Spar 18%
    - En prins af verden
    af Mads Dahlgaard

    Med Pythagoras som inspiration til livet Denne bog er henvendt til unge i konfirmationsalderen og kan læses af alle fremefter langt ind i voksenalderen. Den er skrevet til forfatterens to mere end tyve år yngre søskende i forbindelse med deres ’nonfirmation’ som et alternativ til den viden, de kunne have tilegnet sig til konfirmationsforberedelserne. Bogen rummer en mængde livsvisdom og beskriver kort sagt Pythagoras’ liv fra ende til anden. Her kommer den i en udgave, så alle kan få glæde af den.Pythagoras var alt andet end ophavsmanden til den matematiske ligning a2+ b2 = c2, en genistreg han havde med sig fra sine forunderlige rejser til Egypten og Babylon. Pythagoras var hele livet igennem en flittig elev, både i faglige og praktiske sammenhænge. Han var åben og villig til at lære fra andre kulturer end den græske, han var opfostret i, og han tog blandt andet emner som ligestilling med hjem fra Egypten og forsøgte at indføre det, de steder han kom i Grækenland. Pythagoras var en vismand ud over det sædvanlige; han søgte harmonien i livet og verden og så på den baggrund en helhed i universet, som blandt meget andet bragte ham frem til et heliocentrisk verdensbillede med solen som centrum i vores solsystem. Denne nye erkendelse stod i skarp kontrast til det eksisterende geocentriske og mytologiske verdensbillede med en flad jord i centrum af universet og guden Atlas, der holdt himmelhvælvingen oppe. Pythagoras kom frem til, at planeter var sfærer, der drejede om sig selv og om solen, og med deres rotation frembragte de sfærernes musik. Alt stod i matematiske forhold til hinanden, og Pythagoras lagde med harmonierne og matematikken grundstenene til moderne musikteori. Den unge læser bliver med denne bog på en spændende og vedkommende måde introduceret til et stykke historie, nogle politiske begreber og livsanskuelser, der ellers kan være svære at beskæftige sig med. Her er et alternativt livssyn, som beror på frihed, lighed, fællesskab, oplysning og en særlig kærlighed til mennesket, naturen og livet i alle dets afskygninger.

  • Bogen om verden  af Johan Olsen Spar 10%
    af Johan Olsen

    Hvordan er Jorden egentlig opstået? Har her virkelig været helt mørkt engang? Og hvornår kom menneskene til? Den verden, vi lever i, føles ganske velkendt for de fleste af os. Vi kender til solen, til bjergene, til havet og til de dyr, der bor omkring os. Og vi tager helt for givet, at vi mennesker selvfølgelig er her på Jorden. Men sådan har det ikke altid været. En gang var her ingenting. Ingen jordklode, ingen stjerner, ingen giraffer eller rejer og slet ingen mennesker. Der var ikke engang noget lys eller noget rum. Bare helt mørkt.Så hvordan kom vi fra ingenting til den verden, vi bor i i dag med parcelhuse, fodboldbaner, edderkopper og madpakker? Det er det, Johan Olsen prøver at give os svar på i Bogen om verden. Han forklarer os om The Big Bang, der begyndte det hele. Om solen og stjernerne og altings byggesten, atomerne – der er en slags legoklodser, som alle ting er bygget af. Han fortæller om tyngdekraft og de energier, der holder sammen på verden og forklarer om det første liv, der opstod på Jorden og som langsomt og gennem mange millioner års udvikling nu er blevet til græsstrå, rødbeder og ... dig og mig. Lige midt i den verden, vi alle sammen går rundt i i dag. Aldersgruppe +11 år.
