If you are worried that China is beating us, then take a look at this. China is investing heavily in renewable energy. The USA is fighting all forms of green energy.
Reducing dependence on fossil fuels, and diversifying our energy sources could help us get ahead.
It could prevent wars over oil.
Ukraine will become a key ally to Europe if Europe has to deter Russia on its own in case the US scales back or withdraws from NATO-Danish military expert Anders Puck Nielsen
In his new video, @anderspucknielsen.dk explains that Ukraine becomes a key ally in this scenario⤵️

So US is going to blockade the Strait of Hormuz. No oil or anything else gets out. Prices will skyrocket. Nothing could be better from the Russian perspective.

Oh, yeah, that was the Obama Iran deal.
U.S. allies haven’t forgotten about Trump’s tariffs, his threats against NATO, and his curtailing of aid to Ukraine—so he shouldn’t be surprised that they’re unwilling to help him in Iran, @anneapplebaum argues. www.theatlantic.com/ideas/2026/0...

In the world of math, is it possible to take abstraction and rigor too far? The secret math society called Bourbaki, while enormously influential and important, might also serve as a cautionary tale. www.quantamagazine.org/in-math-rigo...
This is completely unbearable. But also like… why are his insane ramblings never summarized like this in the media? We gotta wait for a substack guy to put it together like this?
Så kan jeg roligt forsætte min morgen routine med at spise havregryn.

I charged my e car the other day from 30 to 80% for 3 euros thanks to cheap wind power. These days less dependency on oil is obvious.

Good US did not elect Kamala Harris, so we avoided the 3rd world war. Thanks US.

Heading back to Corn Land from Dairy Land after a day packed with very interesting research discussions
A year ago we were supposed to be getting $2,000 rebate checks, DOGE was going to find $2 trillion in waste to balance the budget, we were going to pay no income taxes because tariffs would pay for everything, gas and home electric bills would be cut in half, and no new wars.
Time will not be nice to the Trump administration.
See you in Amsterdam summer 2027.

Prime Minister Carney speaks on the phone with Prime Minister Mette Frederiksen of Denmark.
A good call with Prime Minister Mette Frederiksen of Denmark today.
Greenland’s future is for Greenland and Denmark alone to decide. We reaffirmed our commitment to sovereignty and territorial integrity and discussed our ongoing work to strengthen Arctic security.
Ireland has dismantled its first commercial wind farm to make way for a step-change in scale. Each new turbine generates more power than the entire 1992 Bellacorick site, illustrating how 3 decades of innovation have compressed land use while multiplying output. buff.ly/goiabIO

I have used a book co authored by Hillier in my teaching when I worked at Odense uni.
If my memory is correct then I had a brief chat with him at the Mosek booth at a Informs conference.
And as a life-long Atlanticist, such affirmations are painful.
And if UK were to have a nuclear deterrent, yes it should have been independent of the US.
“We have done so much for America”: Denmark fought alongside the U.S. in Afghanistan. Now, as Trump eyes Greenland, the families of fallen soldiers have a message for him, @isaacstanleybecker.bsky.social reports: theatln.tc/I8nGcxwO
„As long as we are more afraid of administrative courts and accounting offices than of the Russian armed forces we won’t have a Zeitenwende”
Absolutely worth listening to this conversation between @anderspucknielsen.dk and @carlomasala1.bsky.social !
I can't believe I'm posting this video - but we actually have to have a conversation about the real world implications of America going to war over Greenland.
Let me walk you through it. It doesn't turn out well for us.
