Mathematical physicist at UC Riverside. Wrote This Week's Finds in Mathematical Physics and now the Azimuth blog on mathematics, physics and environmental science.
A vector looks like an arrow; anyone studying math or physics in college learns about these. Bivectors are important too - though less widely taught. You can create a bivector by taking the 'wedge product' u ∧ v of two vectors u and v, and you can visualize this as the parallelogram shown at left here. But in fact, an ellipse or any other flat surface with the same area lying in the same plane is just as good a picture of this bivector. Further, you can add bivectors, so there are bivectors like u ∧ v + w ∧ z that you can't picture as just a single surface. Thus, you need to be good at the al… Related

The majority of proteins are considered undruggable, because they lack a pocket for drugs to bind, or they are ‘intrinsically disordered’, without coherent structure.

Their words
They could have shipped ChatGPT for example, I heard, in 2019. And they never shipped it because they were so stuck in bureaucracy. But they had everything. They had the data, they had the tech, they had the engineers and they didn’t do it.

A bit surprised by how little I've heard about GCP literally fat-finger *deleting a customer account.* Seems like their business was only saved by cross-cloud backups, a practice I previously thought was compliance theater bullshit and will never, ever, ever, question again. Related

Software engineer and writer; former CTO of Wave, now at Anthropic. Blogs at benkuhn.net on attention, engineering management and doing hard things well.
I've been reflecting recently on Wave's growth spurt in 2019-21. Most teams grew 2-4x a year for multiple years, and culture and effectiveness stayed remarkably strong compared to what I'd have expected (or heard of elsewhere). Some thoughts on what might have helped: Related

I remember Antifragile blowing my mind several times when I first read it. It didn't exactly have anything dramatically new to say that I hadn't heard before in some way, but it brought together things in a way that I found compelling. It made me rethink and reevaluate a lot of my life and gave me a useful frame for making sense of things with.

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.
