Scoop: Anduril's Palmer Luckey to invest in stealthy stablecoin startup
The new funding would value Atticus at between $1.5 billion and $2 billion.

"During his time at IBM, he wrote some of the first artificial intelligence software—his "geometry theorem machine" was the first advanced AI program, and the third AI program ever. It is a logical AI system that can prove theorems in planar geometry about parallel lines, congruence, and equality and inequality of segments and angles. Like Logic Theorist, it uses heuristics."

Aggregation of vortex structures in 2D: the blob-wave system and its role in zonal flows
We give a rigorous mathematical result, supported by accurate numerical simulations, of the aggregation of a concentrated vortex blob with an underlying non constant vorticity field: the blob moves in the direction of the gradient of the field. It is a unique example of Lagrangian explanation of aggregation of vortex structures of the same sign in 2D inviscid fluids. A conceptual model of zonal flow maintenance and modulation based on this idea is then developed, which produces shapes in accord…

Polymer-modulated evaporation flow enables scalable self-assembly of highly aligned nanowires
Highly aligned nanowire networks are essential for enabling anisotropic optical, electrical, and sensing functionalities in next-generation devices. However, achieving such alignment typically requires complex fabrication methods or high-energy processing. Here, we present a simple and scalable self-assembly strategy that uses a viscosity-enhancing polymer additive to modulate fluid flows during solvent evaporation. The addition of carboxymethylcellulose sodium (CMC-Na) reshapes the evaporation…

1/ Watched more #openhouse with C again last night (series 3 episodes 1 and 2). It’s common that only one of the partners in the relationship really wants to be there - and the other is going along with it to people please, and out of fear of losing the other one.
I think the reasons and motivations for going into

"Hard to believe, but it has been already almost 20 years since the days when Apple plastered the halls of its Worldwide Developer Conference (WWDC) with huge posters proclaiming “Redmond, start your photocopiers” or “Mac OS X Leopard: Hasta la vista, Vista”. The decade of the 2000s, coinciding with Steve Ballmer’s tenure as CEO, is widely perceived as a lost one for Microsoft, and one of the most visible signs of that decline was, without a doubt, the “Longhorn” saga."

Compactifications of phylogenetic systems and species of electrical networks
We describe new spaces and maps. Our graphical map is a visual and numerical correspondence between spaces of circular electrical networks and circular planar split systems. When restricted to the planar circular electrical case, this graphical map finds the split system uniquely associated with the Kalmanson resistance distance of the dual network, matching the induced split system familiar from phylogenetics. This correspondence is extended to compactifications of the respective spaces, takin…
