Sketchplanations - The Podcast

They use a four-target sketch to show how accuracy and precision differ. The conversation traces precision’s role in the industrial revolution and interchangeable parts. They compare McDonald’s repeatability with artisan cooking and discuss calibration, testing, and measurement limits. The talk also covers beliefs, culture’s turn to craft, and precision needs in medicine, AI, and weapon targeting.

A lively dive into three horizontal marks: hyphen, en dash, and em dash. They cover hyphens for line breaks and joining words, en dashes for ranges and relationships, and em dashes as strong interruptions. There are typing tips, international style differences, underscore origins, and a fun note about AI giving away em dash usage.

They dig into antipodes and why most opposite points fall in the ocean. Map projections and how they warp our planet's appearance get a playful inspection. The conversation covers hemispheric land imbalance, great circle routes for flights, Earth's oblate shape affecting distances, and a thought experiment about tunneling through the planet.

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.Episode Summary:00:00 Introduction the Coastline Paradox04:12 Historical Context and Discovery14:10 Fractals and Natural World Applications17:26 Modern Implications and Analogies24:36 Conclusion and Final ThoughtsExternal Links and mentions on the show:Jono refers to and leans heavily on the writing of Geoffrey West in his book "Scale" to tell the story of how this was discovered.Rob's half-baked fact about The Standardised Meter can be expanded on here.This is what the self-similarity of a Romanesco Cauliflower looks likeHere is the avenue of trees in Bushy Park, in Southwest London that Jono slalomed.Here are more facts on who originally defined the number 'zero' as we know it today.All music on this podcast series is provided by the very talented Franc Cinelli Hosted on Acast.
