ICE Must Be Abolished. Can Truth and Reconciliation Follow? When I see what federal immigration agents are doing, I want them to be punished. But punishment isn't the solution.

I'm back briefly today, with a new piece @sojo.net:

Three demands faith leaders and organizers must make in this moment: Abolish ICE, Welcome Migrants, and Truth and Reconciliation: sojo.net/articles/opi... โš“

Small Rhombicosidodecahedron if u even care.

I know it can be made with a single (incredibly long) modelling balloon because every vertex only has four lines coming from it, so it has an โœจEulerian pathโœจ

One ironic thing about this round of Ten Commandments laws is that the same places mandating posting [their re-written version of] the Ten Commandments are also restricting teaching about slavery, and well, like

โ€œI am the Lord your God, WHO BROUGHT YOU OUT OF EGYPT, OUT OF THE LAND OF SLAVERY.โ€

This is what remains of the Japanese internment camp in #SantaFe. Today, #February19, 1942 FDR signed โ€œExecutive Order 9066โ€ authorizing the military to remove any persons deemed a threat to national security. โ€œRelocation Centersโ€ were set up across the US. 122,000 people put into camps. Remember.

The same reason we rationalize anything: to convince ourselves that everything is ok.

Would you like to see two of my favorite slides I've ever made, from the beginning of my deck about u-substitution?

I did make a joke in class that (d/d5)(5^{-1}) = -1/25, but I donโ€™t think I played it up enough.

โ€œThe Gatheringโ€ is a straight-up mystery that weaves in lots of backstory.

A great mostly stand-alone episode is s3e4 โ€œPassing Through Gethsemane.โ€

The 2-part โ€œWar Without Endโ€ s3e16-17 has some of the most memorable scenes in the series. It might be confusing, but it might also hook you.

Ulysses It little profits that an idle king, By this still hearth, among these barren crags, Match'd with an aged wife, I mete and dole Unequal laws unto a savageโ€ฆ

โ€œThoโ€™ much is taken, much abides; and thoโ€™
We are not now that strength which in old days
Moved earth and heaven, that which we are, we are;
One equal temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.โ€

"due to fundamental mathematical constraints that cannot be solved through better engineering" <- a lot of linguistic gymnastics to say that "hallucinations" are a feature, not a bug

We are rewatching Babylon 5 now that itโ€™s on YouTube and man, that is the platonic ideal of what a space station looks like. Thatโ€™s just what they all look like in my head. The variety of interiors are perfection.

โ€œThat, as our poet Tennyson once said, is the goal: โ€˜To strive, to seek, to find, and not to yield.โ€™โ€

Iโ€™m off to read Ulysses now.

Delenn asks, โ€œWhy Babylon 5?
If the prior four stations were lost or destroyed, why build another?โ€

Sinclair responds, โ€œPlain, old, human stubbornness, I guess. When something we value is destroyed, we rebuild it. If itโ€™s destroyed again, we rebuild it again. And again, and again until it stays.โ€

Babylon 5 is available on YouTube. We watched โ€œThe Gatheringโ€ last night.

Itโ€™s a good time to rewatch Babylon 5. Itโ€™s always a good time to rewatch Babylon 5. But one exchange from this movie particularly hit me.

MAA MathFest โ€“ Mathematical Association of America

MAA MathFest is in Boston this year! I've never been, and always wanted to.

A significantly reduced registration rate for K-12 teachers? And I might be able to bring one of my kids as a "guest"? This may be my opportunity!

Anyone else I know planning on attending?
