People were jumping into action here in Minneapolis — droves of people, comfortable people, white people — not in mid-January, but in •early December•. (And the groundwork started much earlier!)
Community meetings overflowing. Signal groups exploding. Observer trainings filling day after day after day. Mutual aid networks popping up like mushrooms. On and on.
Why? Because we saw brown and Black neighbors being dragged from their cars, dragged from their homes, stalked, terrorized, •kidnapped• with barely the slimmest shadow of due process or legal oversight.

The price of silver smashed through the $90 mark Wednesday morning
for the first time in weeks
as the metal recoups gains it lost after a late January crash,
though the precious metal remains far from the record highs it previously hit above $120.
KEY FACTS
The price of silver is $90.68 as of 9:25 a.m. EST, up nearly 4% but down slightly from a high of $91.18 reached earlier in the morning.

Silver Breaks $90 Mark Again—Fueled By Tariff Uncertainty, Iran Tensions
Silver has recouped some of the losses that it suffered following a price crash in late January.

A minimal wake-vortex model explains formation flight of flapping birds

Abstract: Collective patterns of motion emerge across biological taxa: insects swarm, fish school, and birds flock. In particular, large migratory birds form strikingly ordered V-shaped formations, which experiments and direct numerical simulations have demonstrated provide substantial energetic benefits during long-distance flight. However, the precise aerodynamic and morphological mechanisms underlying these benefits remain unclear. In this work, we develop a reduced-order model of the wake-vortex interactions between two flapping birds flying in tandem. The model retains essential unsteady flapping dynamics while remaining computationally tractable. By optimizing over a six-dimensional state space, which comprises the follower's three-dimensional relative position and three independent flapping parameters, we identify the energetically optimal leader-follower configuration of northern bald ibises. The predicted optimum agrees quantitatively with live-bird measurements. Because of its simplicity, the model allows for direct interrogation of the physical mechanisms responsible for this optimum. In particular, it isolates precisely how the follower's wing kinematics interact with the leader's wake to enhance aerodynamic efficiency. The model predicts an 11% reduction in total mechanical power for a follower in formation flight -- consistent with experimental estimates -- and shows that this saving arises from reductions in both induced and profile power, dominated by decreased profile power enabled primarily through reduced flapping amplitude and, secondarily, reduced upstroke flexion. These results provide a mechanistic explanation for the structure of V-formations and offer new insight into the aerodynamic principles governing collective flight.

While staying vigilant, we’re embracing the chance to catch our breath and to start healing. The city right now has a bit of the feeling of the days after a natural disaster: there is so much damage to repair. Thousands of people are still sheltering at home, understandably reluctant to go to work and/or school. Thousands are facing imminent eviction when March rent comes due.
There’s organizing around rent relief, talk of a rent strike. Food delivery is still in full swing. Mutual aid is not letting up.
