US Navy submarine captain and author David Marquet discusses leadership lessons from turning the USS Santa Fe from worst to best, focusing on “pushing authority to information” rather than pushing information up a hierarchy. Marquet critiques industrial-age leadership language that seeks obedience and creates “bobblehead” agreement, arguing that real engagement comes from giving people decision-making authority,

He also explains “distancing,” as a leadership and decision-making tool: viewing oneself from a third-person, from a different time, and/or from a different place to reduce ego and defensiveness over previous decisions.

A thoroughly fascinating chat with a very talented and fun individual.

Using Jono’s sketch of four archery targets, we discuss why and how accuracy and precision differ.

Using many different examples, we frame the distinction as “accuracy being true to intention and precision being true to itself,” also phrased as doing the right thing versus doing it right.

The sketch is inspired by Simon Winchester's book, Exactly, where precision and accuracy are connected to the industrial revolution via Henry Maudsley’s innovative screw-cutting lathe, micrometer, and the concept of interchangeable parts. The conversation broadens to explore examples in food (McDonald’s vs artisan meals), recipes, recruiting, IQ tests (validity vs reliability), indoctrinated beliefs, gut feelings, culture’s return to individual craftsmanship, AI’s variable answers, LED mask wavelength tolerances, and targeting weapons.

If you like the finer details of grammar and punctuation, then you're gonna love this episode.

We geek out on the subtle, but incredibly important and occasionally crucial differences between three little horizontal lines: the hyphen - the En Dash – and the Em Dash —

Jono explains hyphens for line breaks and compound terms, how usage can evolve into single words (e.g., wildlife, wellbeing), and why hyphen placement can change meaning (e.g., five-dollar bills). The en dash is described as linking ranges and relationships (pages, dates, times, scores, routes, debates, partnerships, negotiations), with notes on how to type it. The em dash is framed as a stronger-than-comma interruption for added thoughts, with style cautions and typing methods. They discuss underscore origins from typewriters, punctuation differences across countries, and how AI popularized em dashes as a telltale sign of machine-written text.

Most importantly though, we discuss why this matters and that if used correctly, they can help avoid misunderstandings.

Have you ever wondered what's happening on the exact opposite side of the world to you?

Wherever you are on our planet, there's a good chance you'd need a snorkel.

In this episode, we explore the concept of antipodes—the exact point on the opposite side of Earth from wherever you're standing. We discover why most antipodes end up in the ocean rather than on land and cover a whole host of fascinating geographic facts, including how the Northern Hemisphere contains the vast majority of Earth's land and population, how map projections distort our view of the planet, and why Earth's oblate spheroid shape means some antipode distances are longer than others.

Along the way, we also raise the big questions like how deep have humans ever dug into Earth and how long it would take to fall through a frictionless tunnel to your antipode.

External Links and mentions on the show:

• Jono's sketch that explains the Mercator Map Projection
• Jono references the Antipodal Map in the book Marvellous Maps by Simon Kuestenmacher
• The 7.6 mile deep hole Jono talks about is the Kola Superdeep Borehole in Russia, initiated by Soviet scientists in 1970, primarily to better understand the earth’s crust.
• Here's Jono's sketch about the thickness of the earth's crust being proportionally similar to the thickness of an apple's skin.

When you want to measure something you take your ruler or tape measure and read off the length right?

But when it comes to measuring the length of a coastline, things get a bit tricky and totally counter intuitive. 🌊

The science and maths of measuring wiggly coastlines reveal that the smaller the unit of measure, the longer the coastline becomes. Jono recounts the origins of this phenomenon from polymath, Lewis Fry Richardson and its further exploration by Benoit B. Mandelbrot. The trio also relate the concept to various other real-world examples, including the surfaces of the brain and lungs, Romanesco cauliflower, and stock market patterns. Additionally, they touch on the philosophical implications of measurement and delve into the concept of infinity.

Have you ever wondered what the colours on the Olympic flag represent?

The Olympic logo is a globally recognised brand and remarkably, it was designed over 100 years ago by the founder of the modern Olympic Games, Pierre de Coubertin.

This time, we discuss the history and symbolism of this design icon ahead of the Winter Olympic Games in Milano Cortina, Italy. We find out about its representation of unity among the five (?) continents (one for each ring), and the careful selection of the flag's colours. The episode also delves into fascinating Olympic trivia, including the evolution of the games, historical moments, and the development of the Olympic motto. Rob also shares insights from filming at the Olympic Museum in Lausanne, Switzerland, for his series 'The Vault,' which explores Olympic history through artefacts found in their archives.

You can watch all 10 episodes of The Vault for free here on the Olympics Channel.

How big is that pile of books next to your bed?

Tsundoku is a Japanese word for buying books and letting them pile up unread. It’s a familiar habit to book lovers everywhere — that growing stack of books you intend to read but haven’t yet. In this episode of Sketchplanations The Podcast, we explore why we buy books we don’t read, why unread books don’t always feel like a bad thing, and what this habit says about curiosity, identity, and our relationship with reading.

In this episode we embrace Tsundoku and our conversation ranges from buying too many books to the joy and guilt of collecting unread books, and how tsundoku can extend to audiobooks, hobbies, and other unread things. If you’ve ever wondered why you buy books faster than you can read them — or felt conflicted about your own unread pile — this episode is for you.

Links to items (mainly books) that we discussed:

• The book that changed Tom's life: Rocket Fuel by Gino Wickman and Mark Winters
• The book from Jono's pile he next wants to start: A few short sentences about writing by Verlyn Klinkenborg
• Robbie is most looking forward to getting started on: Whatever will be will be by Felix White
• Jono recommends cartoons about books and reading by Tom Gauld
• Big Ideas, Little Pictures is the Sketchplanations book by Jono Hey

Tune in to this episode as we unravel the mysteries of family relations—which we figured would be particularly helpful at the festive time of year.

We explore the subtleties of family trees, making our way to 'Second Cousins Once Removed'. We dig into the confusion around generational terms and the importance of knowing your extended family. We share a few family-related anecdotes and cultural differences, such as the Chinese family tree and Icelandic naming conventions. We strongly encourage you to follow along with the sketch at Sketchplanations.com to better understand your own family connections.

Here are the Chinese family tree names mentioned.
