Do you have a syllabus you'd be willing to share?

Universities tend to have strict branding guidelines, including with respect to colors. I suspect that Columbia Blue would have been the appropriate color to use for official communications.

I once read a piece of writing advice saying to avoid multiple directional changes in the same sentence. Had to read “increased lower elevation” like 3 times.

Super real. I've always liked em dashes (counted 39 in my master's thesis from 3 years) and now idk if I can keep using them.

Depends on what exactly the "update" is about. Did she have a surgery or are you just checking in? I'd listen at 2x speed (I do this anyway for most voice memos)

"bloviating." learned a new word today. might also do good to enunciate "horror" a bit less ambiguously lol

Econ (because we are such naughty imperialists) spans such a broad range. Some research is also closer to eg computer science

Martha Fiehn @marthaf.bsky.social · 31/05/2025
well, it’s a social science. Not a natural science. In German, we make this distinction more clearly whereas in the US, we usually use “science” to mean “natural science.”

In German it's also a blue eye. I think the color changes throughout different periods of healing. Sometimes it's also green-ish

haha well, my initial instinct was responding with something sassy like "why don't you leave some food in the fridge for a bit and find out?" or point out that my composting worms also eat fungus that I can't eat. But as an officer in the UCSD Mycology Club, I was curious and googled.

I guess the Eighth Amendment protects against cruel and unusual punishment, not universal punishment

I’m not sure that these are immediately incompatible positions. iirc there’s good evidence that speed cameras reduce racial bias in policing, for instance.

No doubt, I never said otherwise! ICE’s actions are abhorrent one way or the other

Beside the point, but Real IDs are indeed not proof of citizenship. They *are* proof of legal residence, but you can be a non-citizen and get them (I have one as a green card holder, for instance).

It looks like there’s been some downward revision. Googling now I also see 5.2. It was the strongest one I’ve felt before!

The whole building shook right in the middle of micro theory! It’s probably a sign that I should pay more attention to mechanism design

I was just thinking this exact same thing sitting down to do my macro pset. in these times, you can have good days, but you can never truly be at ease.

even with modern technology, parts of hw1 (e.g. around Big Sur) were blocked off for a substantial amount of time recently!

1/3 seems very high. but beyond that, I can see how you get there. I’ve thought about whether I could convince grad housing to let us have chickens given egg prices, and I am growing some fruit + veggies also w grocery prices in mind. now multiply that by indoctrination + religious fervor x100…

How did such a large share of the world’s population escape extreme poverty? Paul Niehaus, Tom Vogl and I were curious and are excited to share with you what we've found. vincentarmentano.com/research/hpf...

I’d be interested in more west coast cities. New England/east coast cities like Philly, NYC, and Boston in particular are featured so heavily in K12 history. But I took an environmental law class in undergrad and learned that LA’s dev history is fascinating!

There’s a great book on SF’s history: “Imperial San Francisco” in case it’s helpful!

Does he speak directly about the impact of his mental health on his worldview or is that just your conjecture?

I've also been thinking about this, especially the decay of social norms! makes me feel like a boomer sometimes

I think they do target MDs much more directly! I don’t follow health policy closely but I have stuff like this in mind: www.propublica.org/article/we-f...

@venturinimiri.bsky.social and @andreamatranga.bsky.social were talking about this just the other day! Wonder how many people get medication they don’t really need and if there are any pop level implications (like antibiotic resistance)

I’ve had thick and plentiful hair all my life but I’ve been getting ads about hair loss and now I’m terrified I’m losing my hair and don’t even realize it cuz I didn’t realize hair loss for women was even a thing

This is also why education is extremely explicitly left to the states rather than the federal government in Germany.

I wouldn't be so sure. There are some researchers who are motivated to find a "cure" for something, but some of it is just happenstance. The PI that happens to have an opening; the cancer research that happens to get funded.

These seeds are meant to be planted before the annual rain season. But it’s been the driest winter in 150 years — since they started recording. So I still planted them now. Hopefully it will rain on Sunday 🌧️🌷🌻 and help put out some of the fires
