Happy π Day! And Albert Einstein was born #OTD 147 years ago!

en.wikipedia.org/wiki/Pi

Isaac Newton used infinite series to compute π to 15 digits, later writing "I am ashamed to tell you to how many figures I carried these computations".

"I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world."

Mastodon, you are a influence...

Since I joined I have ditched most subscription stuff like Spotify, Amazon and Netflix.

Made the swap to Linux.

Started painting.

Now I am considering whether or not I could be a Person Who Bikes Places.

Another good place to use software: election voting systems. Lower cost than proprietary systems and can be independently verified to do what it is supposed to.

Historians, do you have a preferred resource for digital access to historical newspapers? I have library access to a limited version of ProQuest, but it is missing a lot; other newspapers have been digitized, but access is sold by genealogy sites of varying shadiness and opaque pricing #history #econhist #economichistory #socialhistory #histodons

Manet's famous painting Un Bar aux Folies-Bergère never appealed to me. But now I realize its genius and my spine tingles every time I see it.

The perspective looks all wrong. You're staring straight at this barmaid, but her reflection in the mirror is way off to right. Even worse, her reflection is facing a guy who doesn't appear in the main view!

But in 2000, a researcher showed this perspective is actually possible!!! To prove it, he did a photographic reconstruction of this scene. Check it out in my next post.

This blow my mind.

It's the first sunday of March and it's Digital Independence Day again.

If you would like to spend some minutes to install an independent messaging app and get a cool indie messaging address, you might have a look at:

And don't panic: It's easier than you might expect.
