Season 1 Episode 6 - Interview with Helen Czerski author of Blue Machine and Storm in a Teacup

Helen Czerski is an Associate Professor at the Department of Mechanical Engineering at University College London and her research focus is the physics of breaking waves and bubbles at the ocean surface. Since 2011 she has presented a wide range of science documentaries for the BBC on the physics of everyday life, and atmospheric and ocean science. She currently co-hosts BBC Radio 4's flagship climate and environment show, Rare Earth. She is also a central member of the Cosmic Shambles Network. 

Helen is also a science writing hero of mine. I read and loved both Storm in a Teacup: The Physics of Everyday Life (2016) and Blue Machine: How the Ocean Shapes our World (2023).

Blue Machine in particular is a masterclass in science writing. It is epic in scope, the prose is beautiful, the tone is inviting, and it gets the science storytelling balance right: not getting bogged down in details and not flying over the important bits. 

The comparison that comes to mind is Rachael Carson's The Sea Around Us. These days, Carson is remembered for Silent Spring, which jump started the environmental movement in the United States by exposing the detrimental impact of synthetic pesticides such as DDT. But before Silent Spring, Carson wrote not one but three books about the ocean. The Sea Around Us was her oceanic magnum opus, covering all of oceanography that was known up unto the point of publication 1951, which had recently bloomed in the post-war era. This was an ambitious project pulled off with Carson’s signature panache. I see The Blue Machine as the heir to Carson's throne in this tradition. Czerski really pulled off something amazing, a book with elegant prose, ambitious scope, bubbling enthusiasm, and in the end inspirational, simply put this is oceanic storytelling at its finest.

Summary

Full Transcript

Welcome and Introducing Helen Czerski (0:00–5:00)

• I open the show from Melbourne, acknowledging the Wurundjeri people of the Kulin Nation.
• Introduce Book Science as a podcast about how science books are written and why they matter.
• Introduce Dr. Helen Czerski — physicist, oceanographer, BBC presenter, author, and bubble expert.
• Highlight Helen’s background, from explosives physics to ocean science.
• Frame Blue Machine as a major achievement in ocean science writing — compared to Rachel Carson.
• Emphasize the book’s invitation to see the ocean as a powerful, knowable system.

Seeds of Blue Machine (5:00–10:00)

• I ask Helen about a passage in Storm in a Teacup that hints at Blue Machine.
• Helen describes the evolution of the book idea — how it developed over years of curiosity.
• Discusses physics as patterns in the world and the public’s misunderstanding of the discipline.
• Pushback against the elitism of physics — a defense of intuitive, everyday understanding.
• Framing the ocean as a life support system alongside the body and civilization.

Why Write a Book? (10:00–15:00)

• Helen reflects on why she waited until she had “something to say.”
• Critique of performative communication — the importance of contribution over attention.
• Insight into writing as thinking — the book forces deeper articulation of ideas.
• Discomfort with social media’s shallow engagement and desire to fill space without substance.
• The value of earned authority and the responsibility of taking up a reader’s time.

Structure, Storytelling, and Perspective (15:00–20:00)

• I ask Helen about the structure of Blue Machine, citing the “Russian doll” chapter on dead water.
• Helen explains her organic approach to structure — built from nested ideas.
• Emphasizes the universality of physics and the joy of finding patterns across contexts.
• Science writing as perspective-sharing, not just explanation or fact delivery.
• The goal is to leave readers with a mental model — a scaffold for future knowledge.

Curiosity, Cinematic Writing, and the Joy of Play (20:00–25:00)

• We talk about the playful, invitational tone of Helen’s writing.
• Adults are encouraged to stay curious — science is not just for children.
• Anecdote: a reader tempted to push toast off a hotel table to test physics.
• I describe Helen’s scenes as cinematic — she credits her TV work with that skill.
• Discusses Cosmic Shambles' “boring photo” advent calendar — finding wonder everywhere.

Why Books Still Matter + What’s Next (25:00–30:00)

• Helen shares her deep love for books as immersive tools for perspective transfer.
• Books are the most powerful medium for mind-to-mind communication across time.
• We discuss Cosmic Shambles as a curiosity-driven community without snobbery.
• Helen highlights the value of indigenous and non-Western perspectives on the ocean.
• Quick mentions of her BBC Radio 4 series Rare Earth, new book ideas, and summer science festivals.
• I thank Helen and encourage listeners to explore her books and online work.
