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 โจEulerian pathโจ
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
โI 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 โExecutive Order 9066โ authorizing the military to remove any persons deemed a threat to national security. โRelocation Centersโ were set up across the US. 122,000 people put into camps. Remember.

โThe Gatheringโ is a straight-up mystery that weaves in lots of backstory.
A great mostly stand-alone episode is s3e4 โPassing Through Gethsemane.โ
The 2-part โWar Without Endโ s3e16-17 has some of the most memorable scenes in the series. It might be confusing, but it might also hook you.

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

Delenn asks, โWhy Babylon 5?
If the prior four stations were lost or destroyed, why build another?โ
Sinclair responds, โPlain, old, human stubbornness, I guess. When something we value is destroyed, we rebuild it. If itโs destroyed again, we rebuild it again. And again, and again until it stays.โ
Babylon 5 is available on YouTube. We watched โThe Gatheringโ last night.
Itโs a good time to rewatch Babylon 5. Itโs always a good time to rewatch Babylon 5. But one exchange from this movie particularly hit me.
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?
