A day spent exploring Infinity in mutisets rewriting systems. Picked by Cantor for the first infinite ordinal number, infinity is expressed as the letter Omega, ω. It indicates the limit of the sequence of natural numbers 1, 2, 3, 4.. For example, apple^ω means an infinity of apples. Infinity is a saturating value, no finite quantity can be added to or removed from it. wiki.xxiivv.com

Why, in his 1513 “Letter to Francesco Vettori”, does Niccolò Machiavelli so dramatize the simple act of opening a book? Why the stripping off muddy clothes, the donning court robes, the crossing a threshold into “the ancient courts of ancient men” where he asks questions of Livy and Cicero and they answer him? Because for Niccolò the thing was new. He had spent fourteen years running his intelligence on live human contact: Borgia’s menace, a king’s facial expression, a council’s mood... 1/ Related

open source China
Their words
the competitive dynamic in China is more intense because it's more intense. Everyone's chosen to go open source and that creates a system that in my mind is capable of innovating far faster than the competitive system we have here. All the models learn from one another.

Novelist, author of twelve books including Foundry, Bandwidth and Cumulus. Sends a newsletter of monthly book recommendations.
Their words
Playground by Richard Powers is a strange and wonderful novel set (mostly) on a remote atoll in French Polynesia that follows the tangled lives of an environmental advocate, a sculptor, a tech entrepreneur, and a brilliant bookworm trying to escape the grinding poverty of Chicago's South Side. The richly drawn characters drive the story, but what I love most about the book is that it's a love letter to the ocean with prose that comes closer than anything else I've read to capturing what it feels like to, for example, dive a thriving coral reef.

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
