How Math Connects Fireflies, Clocks, and Computing

A fascinating video featuring Steve Strogatz explores the power of mathematics and how it reveals hidden patterns in the world that would otherwise remain undiscovered. In one example, Strogatz discusses a study where he and his colleagues explained why fireflies begin flashing in unison. This phenomenon, initially thought to be purely biological, was redefined as a mathematical problem. Building on these findings, engineers developed a method to synchronize small electronic clocks, demonstrating how the mathematical principles from the study extend to fields like distributed computing and sensor networks. Mathematical abstraction—a cornerstone of mathematical reasoning—strips away irrelevant details, allowing us to focus on the fundamental elements of a problem. This approach uncovers connections and commonalities across diverse phenomena and scientific disciplines. I hope you enjoy the video as much as I did!

How Machine Learning Is Revolutionizing Economic Thinking

A Sendhil Mullainathan delivered a fantastic keynote on Economics in the Age of Algorithms, a talk lasting approximately one hour (at normal speed). In it, he compellingly argues that algorithms (machine learning, AI, etc.) are, at their core, economics. Among the many fascinating topics he covered, I particularly enjoyed how he framed the difference between Estimation and Prediction. Estimation represents the traditional approach to tackling problems, while Prediction is the newer approach enabled by supervised learning (ML). In essence, estimation focuses on optimizing the estimated Beta, while prediction aims to optimize the estimated Y. Sophisticated algorithms that optimize Y (the prediction) are remarkably valuable for uncovering new and strikingly original hypotheses. However, economists (humans) play a crucial role in designing recommendations for payoffs and loss functions, ensuring that ML outputs are meaningful and actionable. Did this triggered your interest? Sit back, relax, and enjoy an hour of insights from one of the great economic minds!

The Joy of Reading: How to Foster Good Reading Habits in Children

A very interesting FT article discusses how to create good and sustainable reading habits for your children and highlights its importance. The key, unsurprisingly, is that they enjoy reading. However, this enjoyment must be relevant compared to other available options. In economic terms, the utility of reading should be at least as high as that of substitute activities like video games. Achieving this balance can be challenging. To foster a love for reading, we need to carve out time in their schedules, starting with 15 to 30 minutes, 3 to 4 times a week. It’s important to select books that might pique their interests. Creating a family Book Club to discuss the books read, where everyone shares their opinions, can make reading a fun family activity. Additionally, making books readily available at home and visiting libraries together can help integrate reading into their daily lives. https://www.ft.com/content/e3878e7e-459b-43aa-a663-ef8e407012a3

"Completed: 'The Art of Intelligence' MasterClass"

Just finished a MasterClass (>1h) on “The Art of Intelligence,” which I found fascinating. There are several key takeaways for my professional life that I'll share in a full post over the next few days. Three former CIA officers are sharing declassified stories and field-tested techniques, many of which haven’t been shared until now. Learn how to strengthen relationships, make better decisions, and be more persuasive so you can get exactly what you want, at work and at home. Learn more about the CIA’s techniques on MasterClass at https://mstr.cl/3BEFO2a. Your mission: Build stronger connections and get what you want out of life. Your instructors: Three former CIA intelligence officers: Brian Carbaugh, former director of the CIA’s Special Activities Center; Dawn Meyerriecks, former deputy director of the CIA for science and technology; and Michael Morell, former deputy director of the CIA. Yeah, pretty intense. Lessons in this online session include: How to Assess Risk Make Better Decisions Build Stronger Relationships Spot Red Flags Mitigate Bias Nail a Pitch https://www.youtube.com/watch?v=bupn1w3PzE4
