Alternate quantum realities: what if Heisenberg stayed at home?

In this episode of Physics World Stories , writer Kevlin Henney discusses his new flash fiction, Heisenberg (not) in Helgoland – written exclusively for Physics World as part of the International Year of Quantum Science and Technology. The story spans two worlds: the one we know, and an alternate reality in which Werner Heisenberg never visits the island of Helgoland – a trip that played a key role in the development of quantum theory. Henney reads an extract from the piece and reflects on the power of flash fiction – why the format’s brevity and clarity make it an interesting space for exploring complex ideas. In conversation with host Andrew Glester, he also discusses his varied career as an independent software consultant, trainer and writer. Tune in to hear his thoughts on quantum computing, and why there should be greater appreciation for how modern physics underpins the technologies we use every day. The full version of Henney’s story will be published in the Physics World Quantum Briefing 2025 – a free-to-read digital issue launching in May. Packed with features on the history, mystery and applications of quantum mechanics, it will be available via the Physics World website.
