@AlexanderGruber Yay, again!
@AlexanderGruber Did you hear about the jury's verdict today? I am in such a good mood, too!
@amWhy that is precisely what i am talking about. 🎶🎶🎶
Yay!! The nation was largely on hold, holding their breaths... Particularly in LA, Minneapolis, Chicago, New York, Washington DC, pretty much every where.
I had not checked the news until after your post.
@amWhy i was sloghtly worried that my apartment would be consumed in a riot fire before i heard the news
I did not call it going this way.
03:03
@AlexanderGruber I was too afraid to call it. I could not grasp that that the jury might acquit, but given the events from Trump's election, this chronic lies, being worshiped by so many people, and the far right, the denials of racism, the Capital insurrection, I have lost a lot of faith in the American people, or at least a good many of them
But I was holding my breath, hoping, praying, But I was afraid to conclude, based on my perception of absolute guilt, the the jury would find the same.
@AlexanderGruber I've been very shocked by my brother since Biden's election. He is entirely critical and dismissive of "Black Lives Matter", blaming them for the destruction of property. When I relayed to him this afternoon the verdict, via a link to a more detailed article/coverage,
he immediately called my on the phone, furious! It shocked me, how angry he was,...
But also watched Harris's and Biden's speeches after the verdict, and was very moved. A day to celebrate!!
@amWhy there are so many people who've fallen victim to gaslighting. it's unbelievable anybody could watch that video and not come to the conclusion that it's murder.
@amWhy yes indeed. fingers crossed for denied appeal.
@AlexanderGruber Exactly! It seems that too many people, "see what they think they know" vs. those who "know what they see".
@AlexanderGruber Indeed!!

I tried to discern the context of messages by @AlexanderGruber and @amWhy. It appears some police officer got punished for a murder. The act of murder was allegedly a case related to racism. Does this have deep political repercussions?
The wiki article has more details than a typical news website and it's really great to see justice being done in a reasonable time.

@ParamanandSingh Haha! I also saw those two in a vocabulary list, but have long since forgotten "abrogate". Abdication is still fresh since it occurs now and then in both real life and in fiction. =P
08:26
@ParamanandSingh Well of course it has political repercussions. It was one of the biggest sparks for the BLM.
It's unfortunate that ethics gets mixed into politics, but it happens.

@amWhy Oh, shoot. I didn't even notice that it wasn't subtitled. Sorry.
This one seems to have subtitles: youtube.com/watch?v=ThmaGMgWRlY
It is so much better when you understand the fatalism of the hedgehog.

@XanderHenderson Great story!
Pop Quiz: Suppose that $\gamma : [a,b] \to \mathbb{R}^n$. What does it mean for $\gamma$ to be a smooth curve?
@XanderHenderson: the derivative of each component of $\gamma$ needs to be continuous.
But this room is not supposed to be used for deep mathematical discussions
It was more about what I am supposed to teach today.
I don't like the author's definition (which is, basically, your definition).
15:11
This is what I knew
(You missed out on an important subtlety: the components of the derivative cannot all be zero simultaneously.)
I don't think that is pedantic---a curve with cusps or corners is not smooth. :P
In any event, I would call such a curve a $C^1$ curve. A smooth curve is $C^\infty$, i.e. it has continuous derivatives of all orders.
Ok i got your point.
But now I'm being pedantic. :D
15:14
Shouldn't that be called infinitely smooth curve
@ParamanandSingh That seems like too much work.
Too many words.
Hahaha
In two dimensions I was aware of the derivatives not being zero simultaneously so that one of dy/dx or dx/dy is well defined.
Roughly speaking, I would use "(continuously) differentiable curve" to describe a C^1 curve, "twice (continuously) differentiable curve" to describe a C^2 curve, and so on.
A smooth curve has derivatives of all order.
Of course, the real answer is "Use whatever definition the author of the book or paper you are reading uses."
Anywho, I have to go teach now.
OK have a good time with your students. Bye
15:28
hello @AlexanderGruber aka hat captain ;)
bonjour
@ParamanandSingh further reading
the hope is that this case and others like it will lead to an end to qualified immunity. the police in america abuse it and use it as a shield for brutality (mostly, but not only, racist brutality) to the point where it was genuinely surprising yesterday when the officer wasn't let off the hook for blatent murder. usually they get away with no punishment.
15:43
@user21820 We need even more ethics in politics than ever. And the greatest seminal philosphers, as early as Aristotle, Plato, etc... etc... knew the difference between "rhetoric" and true argument. In America, politics has been equated with rhetoric, most noticeable in the GOP, who seeks only to win back the Whitehouse in 2014, at any cost.

@AlexanderGruber: hello, I read that article about qualified immunity. Police in India also enjoy some form of immunity in similar fashion. But there are a whole lot more problems with legal/judicial system in India. The glaring example is the rape case of Nirbhaya which happened in Dec 2012 and the final hanging of culprits happened in March 2020 inspite of all the courts giving death penalty.
17:02
@ParamanandSingh I remember that case. It was, I believe, what the US calls a "gang rape", I believe.
@ParamanandSingh It is very pervasive in many cultures, examples of violence against women, even in the US.
17:20
@amWhy Sorry I was imprecise in my original comment and hence gave a misleading impression.
What I meant is that questionable ethics gets mixed into politics.
And that's why, as you say, we have no need for pointless rhetoric, and what we need is good and honest ethics.
17:33
@user21820 Ahh, understood. Spot on!
17:51
@amWhy one thing i keep trying to tell myself is that it's not my responsibility to influence people who aren't "within a neighborhood" of me politically. I might be able to radicalize liberals or educate baby leftists, but I can't say much to centrists or conservatives that will make much difference.
@ParamanandSingh i heard india had a lot of problems with bribery. is that still true?
@ParamanandSingh i remember hearing about that case. surreal. what's wrong with people?
18:18
@AlexanderGruber How true! I just don't understand how my brother can claim, on one-hand, that he hasn't watched the news for year, and yet claims, at the same time, "I know exactly what goes on, hasn't left a mid size city in Wisconsin, an hour from Minneapolis, blah blah... never reads. I suspect "word of mouth", guys meeting for drinks at a bar, co-workers, develop a certain degree of group think. But in the end, my brother explained, "I have enough to be concerned about, then carrying the world
... on my shoulders." He's generally a good guy, but yikes! Apathy is probably as much a problem as racism, classism... people learn to think what will be, feeling powerless.
@amWhy yeah, i get him feeling overwhelmed. it's tough to stay informed. maybe later in life he can learn more once his life settles down.
@AlexanderGruber indeed. I hope.
17 minutes left and counting down.... @Teresa ;D

I presume, @quid, you've seen today's results from the Candidates Tournament. Nepo a solid point ahead, et al.
22:17
@amWhy yes he's in a very good position now. especially as he played Giri already and has white against Caruana.
@quid Wow! He sure is well positioned. I wanted to ask you: is the flag with three horizontal stripes: white on top, middle blue, and bottom red, the Russian flag?
@amWhy yes, I heard there are plans for Trump to travel back in time, like Terminator. ;-)
@quid Hah! ;D
@quid, after my last question, I am wondering why Alekseenko has not tiny picture when hovering over his name. (This question is just a trivial, "I'm curious" question. Should I edit it, or else risk its deletion? :-)
@amWhy yes, and the cyclic permutation next to Giri is the one from the Netherlands.
And the rotation of that one is the French one.
@amWhy I'm sure the blues are not the same blue.
22:33
@quid I'm guessing you are right on that, but your response to my question was very clever!
