@jamesgunn Santa in MCU confirmed?
Matthew Barber with Jill Barber "Where The River Bends"
My favorite Canadian singers. They are brother and sister and normally perform solo but they sing together here.
Don't know if their software is good enough for this already but this is certainly the eventual future of #driverlesscars. Rumors are whatever Apple is cooking will be like this too: no steering wheel or pedals.
If the Bible is mistaken in telling us where we came from, how can we trust it to tell us where we're going?

Twitter was special. But it's time to leave

"Each dot is an entire galaxy containing billions of stars... The galaxies seen in this image are all in the distant Universe and appear as they did 10-12 billion years ago. They are colour coded in blue, green, and red to represent the three wavebands used for Herschels observation. Those appearing in white have equal intensity in all three bands and are the ones forming the most stars. The galaxies shown in red are likely to be the most distant, appearing as they did around 12 billion years ago." ([Source](https://www.herschel.caltech.edu/image/nhsc2010-008a ))
And, yes, the image does look like a picture of a 1970's brown carpet.
There is far too little recognition of the fact that the US Intelligence Community’s ability to discover Russian invasion plans and share them with Ukraine is one of the greatest intelligence successes of the last 50 years and has had a critical impact on thwarting Putin’s imperialist ambitions.
They knew the Russian war plans better than most of the Russian military executing the invasion (who mostly had no idea they were going to war) and even members of Putin’s Security Council! Remarkable!
@mrlyonsmaths that's impossible to answer - there are way to many great math results. But
Among nontrivial things: the fact that geometry can be used to study group theory discovered by Gromov. various dualities, Atiyah-Singer Index Theorem, the fact that homeomrphic but not diffeomorphic manifolds exist.
Among trivial but useful things: Eckmann–Hilton argument.
So, mathstodon. Something a little lighter since it's Sunday and all that. What's your favourite maths fact?
Bonus points if it's incredibly trivial! 😊
Eilidh Stimpson discovered a 135-year-old message rolled up inside an empty whisky bottle beneath her floorboards at her home in Edinburgh.
Signed and dated by two male workers, the message read: “James Ritchie and John Grieve laid this floor, but they did not drink the whisky. October 6th 1887. Who ever finds this bottle may think our dust is blowing along the road.” https://www.edinburghlive.co.uk/news/history/edinburgh-mum-finds-incredible-135-25537021?fbclid=IwAR0xCycSiQ7p9Gn3ppJPZ7jxab1EslEti4QXhSiuqSxCUDVD7afwzqTk-6g
If you need a break from everything here is an #audiobook recommendation:
P.G. Wodehouse Volume 1 narrated by Stephen Fry (who is on mastodon btw at @stephenfry)
I **absolutely love** Jeeves stories and this is my favorite narration.
@allo that is perfect! 😂 👍
Understanding #Mastodon gets easier once you get the basic idea that federation between servers can be understood as homeomorphisms across hyperplanes between the Riemannian manifolds of toots, whereas the servers represent countable finite sets of discrete entities.
Goodmorning Mastonauts! Before we get acquainted today, just one small ask.
Ontario is in crisis right now. Our healthcare system is crumbling, and our pediatric hospitals are overflowing. This link is an impassioned speech by Ottawa Centre MPP Joel Harden. Please consider listening to this, sharing it, and getting just as angry about what's going on.

Gonna explain my profile picture in a few toots...
As mentioned on Twitter recently, in the Feynman formulation illumination is a sum over all possible paths light could take. Use parameter x to specify path with endpoint y. (y typically a 3-vector, x usually high dimensional.) We’re interested in L(x,y), the length of path x ending at y. The illumination at y is ∫exp(ihL(x,y))dx where h is some physical constant.
For what I’m going to say just think of L as some random complicated function...
@existential_wormhole ok, thanks again.
@existential_wormhole thanks. I thought my link led to a free pdf too. at least I was able to download it at the time.
