Sorry, "Coach" Tuberville,

Alabama is 3.5x more deadly than NYC:

NYC homicide rate per 100,000 people = 4.6

Alabama homicide rate per 100,000 people = 15.9

And for context: The overall US homicide rate per 100,000 people = 6.3

@tristansnell That made me look up this stat for Australia. Here, apparently it's 1.

@frogglin @timrichards Happy to do the next four weeks after that. Perhaps there should be a lottery and every Australian takes a turn... likely produce a more moral ethical and overall better financial return for the overall economy than the current system!

So, I gave two talks yesterday at a Physics Teachers conference (Physcon 2024).

Feeling good because, both, apparently (according to attendees), were useful and interesting.

In particular, I feel I've really honed my Special Relativity spiel on Time Dilation (it's taken a while!) - I should really write something up (as promised in previous paper):

"Event-diagrams as formal, pictorial world-maps were developed by Hughes (to be described in a future publication)."

Then again... 1/2

@level98@mastodon.social avatar

I find writing papers dull... so it may be a while! 😀

And the talk generated interest in my online course, so I can just chat to people then. I much prefer just talking to people about these things.

Even better would be in-person, in front of a white-board... but one doesn't tend to get everything one wants in life. 2/2

Me, holding a giant mango margarita with lines it is ridiculously sized I'm not that small

So, returning to drama (acting etc.) "later in life" (not that late, but late enough) and, unfortunately, I'm at most a double-threat:

Acting, tick... singing, tick... dancing, you what?... why did I sign up for this?

OK... so it's not dancing, dancing, just that stuff you do in a play with songs but, that's difficult enough for me!

I'm just hoping that embracing such a challenge really does stave off dementia etc.... there's got to be some benefit to putting myself through this!!

@BackFromTheDud Between Fred and me we'd have all the bases covered! (Though his dancing was in a somewhat different league to my acting and singing.) 😀

@benroyce @Lats @Heliograph I never voted in the UK, but I'm now very glad to be living in Australia where I "have to" vote, and there is rank choice voting. Both seem to contribute to suppressing extremes.

May I remind you of... the Monty Python "Spam Sketch". A commentary on any form of communication. Everything comes served with spam, whether you want it, or not (from email, to junk mail in a physical letter box).

We're all the old lady screaming "I don't like spam!"... and the world just carry's on like everyone else in the sketch "Spam, spam, spam, spam...".

Just your everyday mathematical proof that instead of exploding towards infinity, an infinite series such as 1+2+3... converges to... wait for it -1/12

Anyone else watched this and found it both hard to believe and convincing? Massive implications if true.

I've not done a search on this yet but it's worth a watch first even if it's wrong.

https://m.youtube.com/watch?v=beakj767uG4

level98,
@level98@mastodon.social avatar

@happyborg It's not particularly new, or radical.

I suggest you watch the video linked below for an explanation of what's actually going on.

(I'd recommend Mathologers channel for a bunch of interesting math videos... and Burkard is a nice guy in person, too.)

https://www.youtube.com/watch?v=YuIIjLr6vUA&t=1436s

level98, (edited )
@level98@mastodon.social avatar

@happyborg Yes. This video's newer. I didn't notice this because you mentioned the !+2+3... = -1/12 thing which this is tangentially related to. Tony's drawing a long bow.

!+2+3... diverges to infinity. All that other stuff is really, significantly other stuff.

Good on him for getting people interested in maths, and he's a very smart cookie (as Burkard points out). At the same time, there's unsophisticated/wrong stuff in the original video. BUT this is not an insult, but impressive... 1/3

level98, (edited )
@level98@mastodon.social avatar

@happyborg Tony was happy to play around with this stuff in public (which is what mathematicians / physicists usually do in private) get some stuff somewhat wrong, and learn more about it and run further with it. The struggle of the learning / growing process revealed.

Though the linked paper is not "revolutionary". It is pointing out some interesting "patterns" which may or may not turn out to be of particular use.

Which is... 2/3

level98,
@level98@mastodon.social avatar

@happyborg Essentially what Tony say's himself, and is pretty much a description of what everyone's doing in "that space" (i.e. trying to understand QFT "more deeply"... and or combine it with gravity etc.).

In no way am I putting Tony down (and, in no way am I in a position to do so!) but I'm pointing out the tangential relation to the !+2+3... sum which, "obviously", is infinite.

The 1+2+3... stuff is a bit of marketing (one could say, "click-bait") which, like I said, good on him! 😀

3/3

I am working on a project today.

Can anyone honestly, visually, see the difference between a period and a comma?

Even in Arial Rounded MT Bold, it has to size 36 to even begin to distinguish a visible difference.

Which is one reason I still advocate for two spaces after a period. So that paragraphs don't look like run on sentences.

level98,
@level98@mastodon.social avatar

@UnCoveredMyths Yes. I can tell the difference. And I dislike (the aesthetics) of two spaces after a period; I find it can slow my reading.

The same guy who ran a "Hyperloop" con and a bogus "Transit Tunnels" scam wants us to believe that no Starlinks have been sold directly or indirectly to Russia "to the best of his knowledge".

Meaning, "we haven't been caught yet."

Anytime U.S. elected officials and government agencies want to leave 'X' is fine with me.

@danwentzel Evidence would suggest that "the best of his knowledge" is not a high bar.

    @rooster I hope you don't mind me adding:

    There's an (IMO reasonable) animation on the related Wikipedia page, which is a simplistic representation of exactly this i.e. the quarks of a proton and a neutron being held together by the exchange of gluons (the little coloured dots). This exchange of gluons being the strong force.

    Meanwhile, the proton and neutron are bound by the exchange of a pair of quarks (in this case, a pion) - the residual of the strong interaction.

    If you draw all roots of all polynomials whose coefficients are ±1, you get an amazing picture that raises lots of challenging puzzles!

    I really hope someone reads our short article:

    https://www.ams.org/journals/notices/202309/rnoti-p1495.pdf

    and solves the main puzzle: why do the fractal regions of this set look so much like "dragon sets"? We have a good heuristic explanation, but no proof yet.

    People sometimes get excited about math when they learn about fractals, and then disappointed when they discover rather few professional mathematicians prove theorems about fractals. If you ever wanted to prove a cool theorem about fractals, this could be your chance!

    If you read part 2, I'll show you what I'm talking about.

    (1/2)

    @johncarlosbaez I passed this on to my High School maths students. We are just talking about complex numbers and polynomial roots and thought they'd be excited to be able to understand (at least a fair amount of) this.

    Thanks!
