Every Wednesday I pull a thread from my second brain and chase a new idea, usually where two fields meet. It is my quest to understand a bit more, and wire up a new synapse. Learn along with me.

The bailout behind the Boston Tea Party
The tea dumped into Boston Harbor arrived under a law built to rescue a failing company. That law made tea cheaper, with a tax hidden inside, and that was exactly the problem.

The day genome sequencing outran Moore's Law
The cost of sequencing a human-sized genome fell from $95 million to $525 in NHGRI's series. The crucial break came when laboratories switched methods in 2008. That makes the curve a useful lesson for every technology...

Why nearly every startup is a Delaware C corporation
Business textbooks call the C corporation the expensive way to own a company, because its profits get taxed twice. Nearly every startup that raises venture money picks it anyway. The reason has less to do with the sta...

The Sun went quiet for seventy years. The cold lasted five centuries.
Between 1645 and 1715 the Sun almost stopped making sunspots, and Europe was famously cold. It is the standard illustration of solar activity touching human history. It fails on three independent counts, and the refut...

Apollo's first Moon age came out older than the solar system
In January 1970 the first published radiometric age for lunar material was 4.66 billion years. The solar system is 4.567 billion years old. The number was impossible, nobody had made a mistake, and the gap turned out ...

The AI boom runs on a guess about how long a server lasts
Depreciation turns AI spending into reported profit through a number that accounting rules openly call an estimate. On the same day in January 2025, citing the same cause, Amazon shortened it and Meta lengthened it.

Economics, entrepreneurship, and marketing each have their own theory of disruption, and none of the three mean the same thing by it. One widely used textbook even gets its own theorist's verdict wrong.

What Enceladus doesn't need, and how much time it's had
No magnetic field, no atmosphere, no sunlight, and none of it turns out to matter much. The thread that's still open is a number nobody agrees on: how old the ocean underneath even is.

Earth erased how life began. Saturn may still have a copy
A prediction made in 1993 about a vent nobody had found. What turned up seven years later, and what a spacecraft tasted 1.2 billion kilometres away.

Only two people have won both a Turing Award and a Nobel Prize
Both are AI researchers, on opposite sides of the field's oldest argument. The neat story is that each proved the other wrong. The truth is better.

The culture iceberg in every marketing deck came from an anthropologist
Anthropology and marketing both lean hard on the word culture, and even share the same diagram for it. Then marketing quietly drops the one idea that made the diagram worth drawing.

Some myths are eyewitness reports, and we can check
Three unrelated cultures, three catastrophes, three independent clocks. What happens when you check the stories against the rocks.
