Designing a 2020s Art Deco for Jerusalem

Designing a 2020s Art Deco for Jerusalem

What would a 2020s equivalent of Art Deco look like — one that picks up classical proportion and ornament while integrating everything modernism got right? Architect Hannah asked exactly that, and this episode builds the answer from the ground up. We explore proportional systems derived from the golden ratio, the window-to-wall ratios that align Passivhaus standards with traditional facades, and how Jerusalem's 1918 stone ordinance offers a model for form-based codes. We also tackle the cost objection to ornament — and explain why CNC routers and digital fabrication have made it obsolete. If you're an architect who wants to design something beautiful, traditional, and genuinely contemporary, this is your starting point.

How to Label a Ziploc Bag (Chemistry That Works)

Why do labels refuse to stick to your vacuum-sealed bags? It’s not bad luck — it’s surface energy. This episode breaks down the physics of polyethylene, the best surface prep techniques (from isopropyl alcohol wipes to the packing tape trick), and which label materials and markers will survive long-term storage. A practical toolkit for anyone tired of mystery bags in the closet.

What Were Ancient Tefillin Actually Made From?

Most people assume ancient tefillin were made from goat leather because goats were common in the ancient Levant. But a 2021 study using FTIR spectroscopy on 2,000-year-old samples from the Qumran caves tells a different story. This episode explores the actual materials science behind tefillin: why calfskin outperforms goat leather for preserving parchment scrolls, how modern batim are graded from gassot to peshutim, and what the Talmud actually says about acceptable hides. If you've ever wondered about the practical craftsmanship behind these ritual objects, this one's for you.

Mansfield's Wandering Boulders: Geology Meets Folklore

In Mansfield, Connecticut, massive granite boulders aren't just lawn ornaments—they're community anchors, wedding venues, and the subject of a century-old mystery. This episode explores why this town has four times the glacial erratics of neighboring areas, from the unique pink-feldspar Mansfield Granite to the Willimantic River valley's glacial debris chute. We trace the science behind the "Wandering Stone" (which actually moves 3 inches per year), the 50-year tradition of the Mansfield Rock Fair, and the legal battle that saved Hannah's Rock from demolition. Discover how geology shapes identity—and why some things are too heavy to move, in every sense.

Why German and Japanese Manuals Are So Good

Why do products from Germany and Japan consistently come with such thorough, well-organized manuals? This episode unpacks the structural systems behind the reputation: Germany's Duale Ausbildung apprenticeship program and product liability laws, Japan's monozukuri craftsmanship philosophy and kaizen continuous improvement. We explore how DIN and JIS standards create shared languages for documentation, the surprising history of "Made in Germany" and "Made in Japan" as stigma-turned-badge-of-honor, and what other countries can learn from these two very different but equally effective approaches to technical documentation.
