#US #fiscal state is everyone's issue
"US #debt now stands at $36tril, or 124% of GDP.. #America is no longer part of the elite group of ultra-safe #borrowers: countries like Germany, Switzerland & Singapore.. In 2024, #interest payments reached $881bil, making them one of the largest components of US #federalbudget, even surpassing #spending on #defence & #Medicare..🤦‍♂️ #Trump & congressional #Republicans cld unleash widespread #financial #instability"

https://www.bangkokpost.comUS fiscal state is everyone's issueAs Donald Trump's "big, beautiful" tax bill heads to the US Senate, investors everywhere are growing increasingly uneasy. On May 16, the credit-rating agency Moody's downgraded US sovereign debt from its long-held triple-A status to Aa1 -- following similar decisions by Standard & Poor's (in 2011) and Fitch Ratings (2023). Given the sheer volume of US debt -- which now stands at $36 trillion, or 124% of GDP -- and rising interest costs, these institutions have concluded that US debt metrics are no longer in line with those of similarly rated sovereigns.

Cap (pileus) clouds over the cumulus in the mountains of southern New Mexico.

en.wikipedia.org/wiki/Pileus_(

Note the Skew-T trace for this location. Winds are fairly light in the convective zone, but above that the winds increase. (But wind direction does not change.)

Humidity hits a maximum just above the convective layer, which is where the cap clouds form.

#WarrenBuffett warned Saturday of the dire consequences of #Trump’s #tariffs while telling the thousands of #investors gathered at his annual meeting that “#trade should not be a #weapon” but “there’s no question that trade can be an act of #war.”

Buffett said Trump’s trade policies have raised the risk of #global #instability by angering the rest of the #world.
“It’s a big mistake…when you have 7.5B people who don’t like you…, & you have 300M who are crowing about how they have done,” he said.

If you want a great documentary on the effect of tariffs with actual business holders in the computing / electronics space.
See how things are going and you as a consumer will be affected.

I highly recommend you boost / share, GN did a great job. Meet company founders, ceo's of small and big companies. Understand how they are dealing, with the current economy we are in, etc.

3 hours documentary.

A Stellar Look at NGC 602

The young star cluster NGC 602 sits some 200,000 light years away in the Small Magellanic Cloud. Seen here in near- and mid-infrared, the cluster is a glowing cradle of star forming conditions similar to the early universe. A large nebula, made up of multicolored dust and gas, surrounds the star cluster. Its dusty finger-like pillars could be an example of Rayleigh-Taylor instabilities or plumes shaped by energetic stellar jets. (Image credit: NASA/ESA/CSA/JWST; via Colossal)

Ultra-Soft Solids Flow By Turning Inside Out

Can a solid flow? What would that even look like? Researchers explored these questions with an ultra-soft gel (think 100,000 times softer than a gummy bear) pumped through a ring-shaped annular pipe. Despite its elasticity — that tendency to return to an original shape that distinguishes solids from fluids — the gel does flow. But after a short distance, furrows form and grow along the gel’s leading edge.

Front view of an ultra-soft solid flowing through an annular pipe. The furrows forming along the face of the gel are places where the gel is essentially turning itself inside out.

Since the gel alongside the pipe’s walls can’t slide due to friction, the gel flows by essentially turning itself inside out. Inner portions of the gel flow forward and then split off toward one of the walls as they reach the leading edge. This eversion builds up lots of internal stress in the gel, and furrowing — much like crumpling a sheet of paper — relieves that stress. (Image and research credit: J. Hwang et al.; via APS News)

The growing conviction that #Trump will stick by massive new #tariffs regardless of the economic fallout — amplified by Trump’s refusal to rule out a #recession on Sunday — fueled the drop across equity markets. The Dow Jones Industrial Average closed down 890 points, 2%, while the S&P 500 fell 2.7% & the Nasdaq Composite plummeted 4%.

#Trump’s senior advisers downplayed fresh economic turbulence Monday as the admin’s escalating #TradeWar deepened a sell-off on #WallStreet & renewed fears about the stability of the US #economy.

As all 3 major US #stock indexes slumped, Trump’s team projected confidence that the volatility would prove temporary & that an economic boom set off by tax cuts [for #corporations & the #wealthy] would follow later this year.

For crying out loud, like a drunk toddler & for seemingly no reason at all, #Trump has now reversed his #tariffs on #Canada.
Trump said Thurs that he would allow BOTH #Mexico & Canada to avoid tariffs on most exports to the #US for 1 month, specifically products subject to the #USMCA, the #trade pact he signed in his first term.
The move came less than a day after he granted a 30-day reprieve to #automakers, & hours after announcing a pause on Mexico’s tariffs.

For rank-and-file workers, the latest move by #Musk underscored a climate of #instability & #fear inside the #FederalGovernment. One staff member at the National Institutes of Health, who spoke on the condition of anonymity out of fear of retaliation, said she was shocked by the message, which she said left her with a sick feeling in the pit of her stomach. When she found out more of the context, she said, she messaged a colleague: “They’re terrorizing us.”

Visualizing Unstable Flames

Inside a combustion chamber, temperature fluctuations can cause sound waves that also disrupt the flow, in turn. This is called a thermoacoustic instability. In this video, researchers explore this process by watching how flames move down a tube. The flame fronts begin in an even curve that flattens out and then develops waves like those on a vibrating pool. Those waves grow bigger and bigger until the flame goes completely turbulent. Visually, it’s mesmerizing. Mathematically, it’s a lovely example of parametric resonance, where the flame’s instability is fed by system’s natural harmonics. (Video and image credit: J. Delfin et al.; research credit: J. Delfin et al. 1, 2)
