Understanding the real direction in which time flows restructures the world. It gives the reader cause for well-founded, enlightened optimism.
This volume describes with great clarity the significance of chemistry as the foundation of evolution: from star dust to self-replicating molecules to chemical proliferation and, gradually, to the development of the first cells. It explains in depth the significance of mutations that led to photosynthesis and complex cells, which was ultimately what made the unbelievable diversity of multicellular organisms possible in the first place.

Wie wäre es, wenn Software-Pionierin Ada Lovelace aus dem 19. Jahrhundert in der Jetztzeit landet und ihrem Freund Charles Babbage, einem Computer-Vorreiter aus England, Briefe schreibt? Darin erklärt sie alles, was man über das Thema Digitalisierung wissen muss – verständlich für jede und jeden. Es geht um Nullen und Einsen, um Verschlüsselung und virtuelle Realität, um Bitcoin und Blockchain, um Handys und Hypertext. Genau das macht Anna, die unter dem Pseudonym Ada L. einen Blog startet: über das, was die digitale Welt im Innersten zusammenhält. Die digitale Nomadin arbeitet in Thailand und Australien, im Elektrobus reist sie durch Europa. Auf ihrer Tour knüpft sie Kontakte, verliebt sich und kommt üblen Machenschaften auf die Spur. Dabei gerät sie selbst in Gefahr. Hilfe kommt von Freunden, von Fremden – und immer wieder von Hühnern.
