Innate: How the Wiring of Our Brains Shapes Who We Are by Kevin J. Mitchell

I used to work for Princeton University Press (PUP), and once in a while I go look through their list of new releases. There was a time when I read the whole printed catalog cover to cover in the course of my duties; it always made me want to get hold of the books and become more informed on topics ranging from the geology of South America to… Dining Posture in Ancient Rome.

Now, it’s no different. I see PUP books, I want to learn stuff! A while back I heard about a PUP sale, and made a list of books to be considered for purchase (as ebooks, since I’m out of range of most English-language book supply chains, and the books I can get aren’t cheap). But I don’t like forking over money for ebooks, because I don’t feel like they’re mine, I can’t see them on my shelf, and there’s a limitless supply of public domain ebooks that I can read for free. So in the end, I narrowed the shortlist down to just one book, this one. It purports to answer a compelling question, one that’s addressed to some extent in the twin studies book I read recently: What makes us who we are?

Entwined Lives by Nancy L. Segal

My reading is about half fiction and half non-fiction; among non-fiction books, there are a lot of pop-science books; among the pop-science books, there are a lot of pop-psychology books. Some of the pop-psychology books have made interesting (but rather isolated) statements about twin studies. These statements intrigued me; surely the scientific study of twins deserved to be described in more depth. Finally, I’ve read a whole book about twin studies!

Author Nancy L. Segal is a researcher (and a twin) with an early 2000s-style website and a number of books to her name; this book, Entwined Lives: Twins and What They Tell Us About Human Behavior, isn’t the most recent book she’s published, but seems to be the most general. It may actually be the most accessible, general book on twin studies in existence. So if the topic interests you, read on.

When and Why I Read Entwined Lives

FINALLY I'm reading a book that I hope will shed more light on my understanding of the nature/nurture debate from the perspective of twin studies. Once in a while I read a sentence that suggests a surprising amount of similarity between identical twins is innate (twin brothers separated at birth both walk backwards into the sea?), but of course the reality is complex. And maybe after this I can read a book that's more recent than 1999, lol.

Fluorite from Wuyi

Item description / significance
This is a group of seven fluorite display objects, each on a wooden stand:

  • A mostly green polished sphere with a purple stripe (stand can rotate)
  • A smooth translucent purple lizard carving
  • A rough purple and green lizard carving with white crystals
  • A bright green translucent “kryptonite” natural crystal formation
  • A sparkly purple natural crystal formation
  • A polished slice of purple and green fluorite with white “feathers”
  • A purple three-legged “wealth toad” carving

Bought where
in Wuyi, Zhejiang Province, China, in a shop inside a residential complex

Age and origin
basically new, from Wuyi

What I like about them
There are so many kinds of fluorite… each of these pieces has unique characteristics in terms of color, texture, shape, size, and interaction with light, thus they attracted me for different reasons. The polished flat slice is the thing that struck me first, and seemed unique in the shop; the pure bright green crystal caught Siqi’s attention; the sphere has a purely symmetrical shape and smooth texture that minimizes distraction from the stone’s colors; I wanted a piece that showcases chaotic sparkly square crystals; and I wanted at least one animal carving.

Other notes
I bought two lizards even though I usually don’t buy two similar items. The logic is, if I buy two similar things, then I will probably wind up liking one more than the other, and the less-liked one will cause regret by seeming redundant. I decided that the lizards were both spectacular enough, each in its own way, and that I’d regret leaving either of them behind.

See below for more on how we found the shop where I got all this stuff, and photos of the items. In particular, the crystal on the far left really is bright green, though it doesn’t look green at all in the photo above!

“English” on signs in Wuyi and Jinhua

Below are five funny English text samples I saw on a brief road trip with my husband Siqi and his parents to Wuyi, Zhejiang Province (a city with a population of 460,000). On our way back to Hangzhou, we passed through Jinhua, Zhejiang Province (a city with a metro area population of 1,258,000).

Wuyi Old Town

We visited the “old town” retail street in Wuyi for lunch and dinner. See below for photos.

Wuyi Fluorite Museum

There’s a trip.com page about this place, and a couple of stilted English-language news articles that mention it, and that’s all.

Hello, Wuyi Hot Spring Fluorite Museum!

The museum was two floors of rooms, laid out like this.
“Schematic diagram of the distribution of fluorite ore resources in China” and “Distribution map of fluorite despots in Wuyi Count” (inset)

See below for info on 4 Guinness World Records related to fluorite, and photos of the minerals on display.

Trip to Wuyi, Zhejiang Province

I live in China. I’ve had the thought that while I’m here, I should look into buying minerals that are mined locally, since presumably such treasures can be had for a fraction of the price they sell for after being exported.

I had the impression that China is known globally as a source of fluorite. I did an online search, and went to a geological museum in Hangzhou, and learned that the county of Wuyi (population 462,462), which belongs to the city of Jinhua, has fluorite mines and a fluorite museum. Therefore, during the Chinese New Year Holiday, I went with my cooperative husband and in-laws to Wuyi in search of beautiful stones. I assumed, since Wuyi has fluorite mines and a fluorite museum, that it also had shops selling fluorite products. If it does, we couldn’t find them! Nevertheless, our road trip shopping quest was successful.

The trip is documented in this post and five others:

We stayed two nights (February 1 and February 2) in the Vienna International Hotel in Wuyi. There are… 26 miscellaneous photos from the trip below.

Happy Year of the Snake!

The Western zodiac has 12 symbols, one for each month. The Chinese zodiac has 12 animals, each celebrated for a whole year. This year is the year of the snake. I like the idea of the zodiac animals in general, and I like snakes in particular.

Below are a handful of photos of snake products and decorations specially arranged for 2025.

Return to Lin Feng Mountain

Siqi and I went to this place on New Year’s Eve in 2022 and got some great photos of the early winter sunset.

ยป Previous visit to Lin Feng Mountain

We recently returned there with his parents. We went earlier in the day, and the visibility was better, so the photos are quite different this time!

See below for 39 photos of the observation tower and Hangzhou from the observation tower, plus mountains in the distance and plants up close, among other things.
