Erwin Brecher Knihy

Chytré knihy z edice Mozkovna - to je téměř 150 stran plných rébusů a zapeklitých hádanek. Zabaví každého nadšence do nevšedního luštění. Čekají vás logické úkoly od školácky jednoduchých až po ďábelsky zapeklité, hlavolamy k testování logického uvažování, hádanky od předních řeckých filozofů, procvičíte si šedou kůru mozkovou, dozvíte se, zda lze postavit stroj času, proč se zdá, že se velikost Měsíce mění a mnohem více.

Vědecké a matematické záhady založené na principech fungování skutečného světa. Zjistěte, proč se velikost Měsíce mění nebo jaký zvuk vydávají kostky ledu, když je hodíte do horké polévky. Každé řešení problému obsahuje odborné vysvětlení napsané nevědecky (a tedy i pochopitelně).
