Some leftists have criticized #NoKingsDay2 as useless. Though it was the largest protest in US history, it didn't change anything. I would go further to say that protests like these generally won't change anything. Dictators aren't forced to step down by 2% of the population coming out for one day. If they're forced to step down by protests, those protests are sustained. They are every single day. They are accompanied by general strikes.
We've been watching that happen all over the world. Portland in 2020 gave us a taste of that in the US. The George Floyd Rebellion was the type of resistance that actually brings down dictators like Trump. Occasional protests, no matter how large, can simply be ignored. That is precisely the reason the US developed a militarized police force in the first place. You need more, more than the largest protests in US history, more than Occupy, more than the resistance of the 60's and 70's, more than, and different from, anything we've seen in our lives.
And yet... Each protest has grown, and grown bolder. Some have grown more persistent. If you think of protest as the path to achieve change, you will lose. It is not. But it is a path to escalate. Some people, some otherwise comfortable white folks, came out for their first time. Some people got pepper sprayed for the first time. Some people questioned authority, stood up for the first time, and have had an experience that will radicalize them for the rest of their lives.
Protest is not useful in and of itself. It is training. It's making connections. Authoritarian regimes rely on the illusion of compliance, so visual resistance does actually undermine their power.
Liberals like to teach that non-violence is all about staying peaceful no matter what, that there's some way that morality simply overwhelms an enemy. I remember reading Langston Hughes' A Dream Deferred in high school. I said it was a threat. My teacher said, "you're wrong, he was a pacifist." Pacifism is a threat. If you can spit at me, beat me, shoot me, and I will not move, if I have the strength to absorb violence without flinching, without even rising to violence, what will happen when you push me too far?
What happens to a dream deferred?
Does it dry up
like a raisin in the sun?
Or fester like a sore—
And then run?
Does it stink like rotten meat?
Or crust and sugar over—
like a syrupy sweet?
Maybe it just sags
like a heavy load.
Or does it explode?
For peaceful resistance to work, there must be ambiguity. It must not be clear if or when the resistance will stop being peaceful. Peaceful resistance with no possibility of escalation is just cowardice.
My critique then is not so harsh as some other anarchists. If you think that protest alone will work, you're probably going to lose. If you are prepared to escalate, if you are prepared to absorb violence without flinching, then it could be possible for protest alone to topple the dictator. The cracks are already beginning to show.
And then what?
The problems that lead to the George Floyd uprising were never resolved. The problems that lead to Occupy where never resolve. The DAPL was built, protesters were maimed, it leaked multiple times (exactly as predicted). Segregation never went away, it only changed forms. The fact that immigrants have different courts and different rights means that anyone can be arbitrarily kidnaped and renditioned to an arbitrary country. We never did anything about the torture black site. FFS, people can still be stripped of their voting rights and slavery is still legal in the US. The people who control both parties in the US are killing our children and grand children with oil wars and climate change.
Toppling the dictator does nothing to resolve all of the problems that existed before him.
No, #NoKingsDay was absolutely not useless. #NoKings and related protests are extremely useful but they aren't sufficient. But, I think we still need to challenge the movement on two points:
How do you escalate after you're ignored or brutalized?
What do you demand after you win?

I saw an article about how good the food options are that are associated with churches. So I went to a Vietnamese place called O BACH across the road from Bunnings in Tuggeranong and had a pretty nice banh mi. Nice crispy bun!
Apologies, I neglected to photograph my food before it disappeared into my cake hole.

Updated my 2020 MacBookPro to 26.0.1. It never booted right again. After trying everything and talking to Apple Support the answer was “do you have a backup”? I had to wipe the drive and start from scratch. Now I’m trying to restore from a NAS Time Machine backup.
Ugh.

Effects of hadronic molecule $N(2080)3/2^-$ on $K^{* }\Lambda$ photoproduction

Effects of hadronic molecule $N(2080)3/2^-$ on $K^{*+}Λ$ photoproduction
In our previous work [Phys. Rev. C {\bf 101}, 014003 (2020)], we have analyzed all available data on differential cross sections and spin density matrix elements for the $γp \to K^{\ast +} Λ$ reaction using an effective Lagrangian approach. There, the $t$-channel $K$, $K^*$, and $κ$ exchanges, the $u$-channel $Λ$, $Σ$, and $Σ^*$ exchanges, the $s$-channel $N$, $N(2060)5/2^-$, and $N(2000)5/2^+$ exchanges, and the interaction current were taken into account in constructing the reaction amp…

Good Morning #Canada
Finally, arriving at our our 10th province, Manitoba, and putting this series to rest means no more nightmares. Friendly Manitoba, it says so right on their license plates, also has hundreds of abandoned towns, but today we'll focus on Scarf. Named for William Scarf, not for winter clothing or the more recent term for eating quickly, the settlement began in the 1880s, started to flourish after train service arrived in 1907, and died slowly after train service stopped, with the last residents leaving in the 1980s. But in 2013, the regional mayor decided to sell parcels of land in the ghost town for $10. I wasn't able to find out if this plan to bring Scarf back from the dead was successful, but perhaps the area is cursed. In 2020, a tornado touched down near Scarf, killing two teenagers when their vehicle was swept off the road.

Localised Arrowheads: The building blocks of elastic turbulence in rectilinear, sheared polymer flows

Localised Arrowheads: The building blocks of elastic turbulence in rectilinear, sheared polymer flows
Pressure-driven flow of a dilute polymer solution has been numerically observed to possess a form of elastic turbulence which is organised around the interactions of localised versions of 2-dimensional `arrowhead' travelling waves (Page et al. Phys. Rev. Lett. 125, 154501, 2020). As a step to confirming this theoretically, we identify spanwise-localised arrowhead travelling waves by tracking a symmetry-breaking bifurcation of the known spanwise-invariant (2D) arrowhead to a spanwise-periodic st…

Atmospheric rivers and winter sea ice drive recent reversal in Antarctic ice mass loss

Atmospheric rivers and winter sea ice drive recent reversal in Antarctic ice mass loss
Since about 2000, the total mass of the Antarctic Ice Sheet (AIS) has declined at a near-linear rate, increasing global sea levels. Since 2016, however, satellite gravimetry data reveal a slowdown in net AIS mass loss and a net mass gain since 2020, despite increases in dynamically-driven ice loss by discharge from outlet glaciers. Here we use a suite of reanalyses and regional climate models to show that this reversal is caused by increased precipitation and positive surface mass balance anoma…
