PM2.5 is at 104ug/m3 indoors with an open window.
Looking at this week, it seems like today is indeed the worst day so far.
This is what I came up with.
There's a HEPA in the magic blue box. Closed off all other windows that could act as air intake. Turned on the bathroom and kitchen fans. They take air from the inside and exhaust it outside. We're doing ~600 CFM at the intake pipe. The HEPA is tiny in comparison to what a Corsi-Rosenthal box uses but it's compensated by having a high static pressure fan that can pull much more air through it. If it didn't work I was gonna go to CT to get some filters and a fan. :D

I got a steady cache of Moldex 2600 for viral particulate reasons. 😂
I don't like the things you're saying. 😂😔 I'm gonna look into a filter now.
Do you mean it's somehow worse than sitting next to a burning fire?
All those buildings over the tree line should be fully visible.

And long term economic planning, and therefore public investment in science.
China’s biotech industry has evolved to the point that U.S. and European pharmaceutical giants in the last several months have spent billions to acquire China-developed drugs that could treat cancer if commercialized with regulatory approval. In March, British pharmaceutical giant AstraZeneca announced it will invest $2.5 billion in a research and development center in Beijing.
In case you thought research isn't subject to outsourcing.
There's a different line for the poor.
The funders who funded him, the think tanks that created his policy, the media that propagandizes his voters, the voters that vote for him, none of those are going away, and the feedback loops connecting them don't seem likely to be stopping anytime soon.
There's still time to catch it if you're around.
If you want to catch the next one, head to their page and keep an eye.

Lately I've had some obviously inaccurate measurements from my Timemore Black Mirror scale. That would happen occasionally but not always. I was charging it today and as luck would have it, I was sitting beside it. I typically charge it unattended. I noticed that it took a very long time to charge and multiple times it seemed to restart charging. I grabbed it to check the cable and noticed it was quite warm in one spot. I though - that's alright, it's likely where the battery cell is, it's charging, lithium cells get warm during charging. Later I took it off the charger and while handling it I examined the hot spot a bit more. I noticed that when I squeezed the scale at that corner, the top plate wouldn't sink towards the bottom as it does in the other corners. A few mental calculations later I figured this could be a swollen cell that has grown so large that it impacts the plates and doesn't let them come together as they do normally. I took it apart. Lo and behold this spicy pillow:
The marking on it means it's supposed to be 8mm thick. It's currently closer to 12.5mm. Removing the battery allowed the two plates to come together in all corners as normal. That confirmed the hypothesis. Further, the reason why it only occasionally impacted the measurements is likely due to the weight of the cup I was using. When using a lighter cup, the total weight would be lower than needed to get the two plate to touch the battery and produce inaccurate measurement.
I ordered this as a replacement. It fits the dimensions and it's got some safety certification.
To check if your scale is a fire hazard, squeeze this corner:
Normal squeeze action looks like this. Unfortunately I didn't record a video prior to removing the battery.
If it the two plates come together as the do in the other corners, you're probably okay. If the plates don't come nearly as close, you've got an unlit petard in your hands.
