Why Your RGB Bulb Is Useless for Sleep Lighting

Can One Person Really Build a Whole House?

You've seen the YouTube videos. One person, some lumber, and a dream — building an entire house from scratch. But what does that actually look like when you're standing in front of a pile of materials with a nail gun you barely know how to load? This episode tears down the gap between the tiny-house fantasy and the real-world grind of foundation work, electrical rough-ins, and a 900-page building code book written in ghost stories. We break down the skill stack, tool costs, time commitment, and physical toll of going solo — and why the DIY dream often meets its match at the frost line.

Where Does Unclaimed Land Still Exist?

A listener asks whether buying raw land to build on is a smarter path than the property ladder. The answer leads through Ottoman land codes, Israeli leasehold mechanics, and the last unclaimed desert on Earth. Herman traces how every chain of title ends at a government — and reveals why truly free land doesn't exist anywhere habitable.

Why Gold, Silver, and Bronze? The 5,000-Year-Old Metal Hierarchy Explained

Why is gold always first, silver second, and bronze third? It's not just scarcity. This episode traces the metal hierarchy back 5,000 years—from the first gold artifacts worked before the Bronze Age to the divine sun-metal link in Egypt, Inca, and Hindu cultures. We explore why platinum was once considered worthless, how the Potosí silver mine flooded the world without disrupting the ranking, and why the Olympic medal system is surprisingly modern (1904 St. Louis). Chemistry, psychology, religion, and path dependence all locked this order in place.

Why Isn't Modafinil Used More for ADHD?

Modafinil is a eugeroic—a wakefulness agent that tickles the dopamine transporter and activates orexin neurons. It looks like an ADHD drug on paper, but clinical trials consistently show it's inferior to first-line stimulants. This episode unpacks the pharmacology, the clinical evidence, and the one scenario where modafinil might still have a role: comorbid ADHD and depression. We explore why a drug that works well for narcolepsy never crossed over.

Where Does the Three-Class Model Actually Come From?

The three-class model of working, middle, and upper class feels inevitable — but it's not an official government classification anywhere. It's a folk taxonomy, a social shortcut we all use even though nobody agrees on the boundaries. This episode traces the model from Adam Smith's economic analysis in 1776 through Marx's political weaponization, Weber's three-component theory of stratification, and Bourdieu's concept of cultural capital. We also explore how the US, Israel, and the UK measure class differently — and why income alone is a weak predictor of class identity.
