What are some of your over-researchings?

It would be interesting to see some. Maybe even lists of them.

Here's a start,

1. How do quartz watches work?Why are they so accurate? Who invented them? How did they become so inexpensive? How did they almost destroy the Swiss watch industry? Why does the quartz crystal vibrate exactly 32,768 times per second, no more, no less? Why and how does that gets transmitted and divided by two exactly fifteen times in fifteen stages by fifteen different clusters of transistors? Who were the "Traitorous Eight" and how did they give birth to Silicon Valley? What did the room look like in which hotel at what address in San Francisco where they all signed the dollar bills and started Fairchild Semiconductor? Why did Shockley want to give them lie detector tests? How did she cut her finger, and why was that suspicious, and how much did she bleed? What was the source of Shockley's paranoia? Where did all these guys live (including exact addresses and dates of moving)? Where did their kids go to high school? Where did they all go to college? What makes and models of cars did they drive? What did their houses look like (including the pictures)? What companies did they start [major ones even to this day, like Intel] and where were they located at first? What are the inner workings of a transistor, and why do the layers matter? What happens between the layers? How does tunneling take place? How much do these quartz modules cost now wholesale? And how does that compare with the original costs? How can this be possible? And so on.

2. A similarly long list of questions about turkey vultures. Fascinating, captain.

3. The story of beautiful Japanese sewing machines from the decades immediately following World War II. Again, a similarly long list of questions. And a collection of beautiful vintage Japanese sewing machines as art objects.

4. The history of the development of the scientific method. And a long long list of questions.

And so on.
