The Invention of Nature: The Adventures of Alexander von Humboldt, the Lost Hero of Science: Costa & Royal Society Prize Winner (English Edition) eBook
This very entertaining and interesting book is now only €3,99 on Amazon.
I haven't finished it yet, but 30% in it reads like a fictional coming of age boyhood adventure. And I guess Von Humboldt's life really was like that 😂

When Reading Went Silent
By the 18th and 19th centuries, the practice of silent reading became widespread. We may not think of reading silently as a subversive act, but many historians recognize it as the key to rising individualism and private thought.

Jane Goodall has died
I knew about Goodall for a long time. I guess she was on a podcast or documentary that I've consumed.
I found this comment by Evanb on HN very interesting:
If you find Jane Goodall inspirational, you may be delighted to learn about Anne Innis Dagg [0], whose studies of wild giraffe predates Goodall's study of chimps. The documentary "The Woman Who Loves Giraffes" [1] is fantastic and has 100% on Rotten Tomatoes. The reason you might not know Dagg's name is essentially that she was denied tenure for being a woman.

Subscribe to my lists of stuff to do in…
These lists publishable as a URL. I love making lists of places that I've been to or would like to visit next time I'm around. In fact some places I've had bookmarked for years before it got to visit them at all.
So here are several of my favorite places to visit in London, Ireland and Schotland.
And here are my favorite places to visit and things to do in the USA and Canada.
Enjoy your travels 😉

GDP per land area.
I knew about the GDP (gross domestic product), a metric for how well an economy is doing.
Mostly, GDP is measured per capita, or in other words, per citizen. So China has a lot of money, but seems poor because it also has a lot of people who need to share that money. It's a few bucks per citizen.
There is however, also another metric, one that maybe is even more useful for comparison.
The GDP per land area. In this metric some of the most profitable land areas on the planet are… exactly where you would expect them to be. Check is out here: GDP per land area.
My only true surprise was Malta. In my imagination it's not a particular rich island. But I guess I was wrong? Or maybe they have a lot of money "on paper" (like Luxembourg's) because the banking laws are very flexible?
