Can someone make sense for me of the fact that a few months ago we made a special deal to import Argentinian beef to ease prices, but now we’re making a special deal to export beef to China? With consumer beef prices at insane levels due to a hard supply constraint?
I get a sense that these people don’t understand their jobs.

Abstract: Rarefied hypersonic bow shocks over blunt bodies inflate as the Knudsen number increases, but it remains unclear whether this inflation is a simple shift and broadening of one common shock layer or a multi-scale change of the macroscopic and internal-energy fields. We address this question using direct simulation Monte Carlo (DSMC) data for Mach-10 flow over a circular cylinder in argon and nitrogen over \(Kn_\infty \approx 0.01\)--\(1\), together with a Mach-number sweep at \(Kn_\infty=0.01\). At low rarefaction, a ray-based density-gradient ridge gives a reproducible bow-shock location and agrees with an independent schlieren-based shock-wave-detection method. As \(Kn_\infty\) increases, this ridge is replaced by a broad kinetic compression layer, so the high-Knudsen cases are analysed using profile-based standoff and thickness metrics rather than by imposing a visual shock line. The Knudsen- and Mach-number sweeps separate two mechanisms. At fixed \(M_\infty\), the continuum normal-shock density ratio provides a useful low-rarefaction reference compression scale, whereas the measured standoff growth is governed primarily by the kinetic mean free path; the effective density thickness shows an intermediate minimum before increasing in the diffuse regime. At fixed low \(Kn_\infty\), changing \(M_\infty\) mainly changes compression strength and curvature, preserving a coherent attached-layer structure. Density-registered profiles and shock-attached proper orthogonal decomposition (POD) show that, within the present maximum-density-gradient registration, density becomes nearly rank one, whereas Mach number and thermal variables retain independent modal content. Rarefied bow-shock inflation is therefore a coupled compression--relaxation process, not a single-scale rescaling of a continuum-like shock.

On Thursday afternoon,
U.S. District Judge James Boasberg heard arguments over whether he should temporarily block the Federal Trade Commission from continuing a lawsuit in the Northern District of Texas targeting the World Professional Association for Transgender Health, or WPATH.
It was the latest high-profile dispute over the Trump administration’s efforts to “end” the provision of gender-affirming medical care for transgender minors
even in states where such care is al…
Judging from comments around and about, it's probably time to post this again.
We will shortly be changing out our roof and installing solar panels and aircon for use in summer in Copenhagen.
Climate is changing - it's time to adapt.
How did air conditioning become a heated debate? - https://giftarticle.ft.com/giftarticle/actions/redeem/39e6beb5-98f5-47ca-9914-cf5f8294a947 via @FT
This week, Reform UK leader Nigel Forage set out his plans
to resign as the MP for Clacton and stand again for his seat,
following a scandal over undeclared gifts, including £5m from the cryptocurrency billionaire Christopher Harborne,
which is being investigated by the parliamentary standards commissioner.
His intention, he has said, is to be judged by his constituents rather than “the establishment”,
arguing that he has done no wrong and that the probe is a “p…

…"The flu killed 15,849 U.S. soldiers in France and another 30,000 in stateside camps. That’s 45,849 killed by the flu versus 26,277 killed at Meuse-Argonne — documenting that the flu was by far our most deadly battle.
More civilians (over 50 million) died from the flu than from both World Wars and the Holocaust combined. Another 500 million civilians were incapacitated by the flu."
