Trump Spends Entire U.K. Trip Trying To Figure Out Where He Knows Prince Andrew From

LONDON—Claiming that he recognized the member of the royal family, but his memory was hazy, President Donald Trump has spent his entire trip to the U.K. trying to figure out where he knows Prince Andrew from, sources confirmed Thursday. “Who is that guy?…

Really blown away by the following calculation of the homology of complex K theory. It's a really unexpected demonstration of how even basic chromatic technology can just obliterate certain calculational problems..

1. We want to compute the homotopy groups of \(H\mathbb{Z} \otimes \mathrm{KU}\)

2. \(H\mathbb{Z} \otimes \mathrm{KU}\) carries two complex orientations; one from \(H\mathbb{Z}\) and one from \(\mathrm{KU}\).

3. The associated formal group laws are therefore isomorphic. Since these are the additive and multiplicative formal group laws, we must have that the associated graded ring is rational.

4. This tells us that \(H\mathbb{Z} \otimes \mathrm{KU}\) is rational, so we may tensor with \(H\mathbb{Q}\) and proceed. This immediately kills that \(H\mathbb{Z}\), since that's rationally equivalent to the sphere.

5. Finally, Chern character gives us a rational equivalence \(\mathrm{KU} \to \prod_i \Sigma^{2i}H\mathbb{Q}\).

All told, we conclude that the homology of \(\mathrm{KU}\) is \(\mathbb{Q}\) in even dimensions and vanishes in odd dimensions with absolutely no messing about with Bott periodicity or calculations with decomposables (as is done in the classical proof).

About an hour ago, my father gathered us and told us that the owner of the tent from whom we will buy the tent contacted him. He told him that he only has 4 days and he will deal with it. Now we do not know what we will do. There is not enough money. Help us before we run out. We only have 4 days. You are our only hope. Send it to everyone. Donation, even a little, will contribute Please.

Hell yeah 🔥🔥🔥

"Coupled with the African Digital Protocol (ADP), the CIX establishes rules for data sovereignty—ensuring that African data remains within Africa unless intentionally exported. This shift protects citizens from surveillance, reduces dependency on foreign-owned platforms, and gives local innovators the infrastructure to thrive."

"Analysts suggest Google, Amazon, and Microsoft are “panicking” because the model undermines their dominance."

I'm looking for work. Outside the US and as soon as possible. I am trans and a public worker, increasingly unsafe. Have a citizenship app pending with Canadian IRCC but don't know when I'll hear. Would be eternally grateful if someone could sponsor a work visa short term so I don't have to stay where I am while I wait.

See the next post for details, and please boost. If you know someone in Canada who could use my help, please connect us.

Bluesky Posters Banned in “Pissgate” Over Charlie Kirk Death

Precisely why I’m migrating my account off Bluesky. It didn’t take long for it to start bending the knee to censorship. And this was just over something petty. If they bent over just for this, what else will they bend over on in the future.
