Did I hear my name being called...

On the topic of the Confederate flag... What we commonly associate with the Confederacy, was not their actual flag. The stars and X bars, was actually a square battle flag adopted for the Civil War effort. The actual Confederate flag went through several iterations, the later of which incorporated the battle flag in the top left corner. See here https://en.wikipedia.org/wiki/Flags_of_the_Confederate_States_of_America The rectangular version of the battle flag, and what we usually associate with the Confederacy, gained acceptance in the 1920s, due in no small part to KKK efforts. It was never a 'legal' version to begin with.

As always, when it comes to D Trump, no-one is ever sure what he really means. However, if you consider freeing the slaves the 'end', then the 'means' to get there involved the bloodiest war in American history. Roughly 360 000 Northerners, and 260 000 Southerners died; the highest American death toll of any war it's been involved in. Actually you can also make the case that the American civil war was not fought to abolish slavery, that was just a 'happy' coincidence. It was fought for economic reasons. All these things could make A Lincoln's motives 'questionable'. But if you haven't figured it out by now, I myself, do not view the past through a 'modern morals' window.

OK, I might have used a bad example, but I'm still uncertain about the term 'bounded'. Lets go back to one of the original examples Markus used. Consider an infinite plane that is bisected by an infinitely long line. Both resulting planes have a boundary, say one on the 'left', and the other on the 'right'. But they are still both infinite planes, so I would consider them 'unbounded'. My question is in regards to the words 'bounded' and 'unbounded'. Does the fact that they have a ( any ) boundary mean they are 'bounded' ? Or does the fact that they are still infinite mean they are 'unbounded'. I'm not sure of the ( confusing ) usage of the words.

I hope they've investigated all other potentialities of releasing these microbes. Too many disaster and zombie movies start out just like that. Does that mean D Trump can have all the Hydroxychloroquine he wants now ? I didn't realise that many people still died yearly from Malaria, and it's still that serious in the 21st century. ( malaria translates to 'bad air' ? )

It goes through zero velocity as it changes direction, but does it really come to rest ? I was thinking more along the lines of placing a ball on top of a steep hill. It is at rest, but unstable. IOW, not in equilibrium, as defined by a lowest energy state. edit: is this homework ?

It isn't actually 'bounded', though, is it ? The area outside the circle is not technically 'bounded', although it has a ( interior ) boundary. ( confusing choice of words ? ) For example, is the set of natural numbers excluding 1 to 10, 'bounded' ? It still goes off to infinity. Is there some other mathematical term that implies a boundary, but is still 'unbounded' ? Or am I simply misapplying the term 'unbounded' ?

I assume your case is very mild, Markus. You seem to have no problem communicating your ideas. You translate the images in your mind very clearly into written word; whereas I sometimes struggle to clearly express even simple ideas, you explain the complexities of GR in very understandable terms.

One could make the argument that protest and social unrest, such as the 1848, European protests/uprisings, or the French Revolution which consumed its offspring, did little to bring about social change. It was subsequent wars ( Italian unification and German unification ) that allowed for self-governance after the failure of the French revolution, Napoleonic empire and the re-distribution of power at the 1815 Vienna Congress. Similarly it was war that brought about the end of slavery ( such as it was ) in the American south. Then again, I suppose you could call civil war, extreme social unrest.

You should be proud and commended for helping this kid, Joigus ( you too Dim, for your work with the differently enabled ). I don't know of anyone ( other than Markus ) who has Asperger's, or maybe I do, but because of the wide spectrum, I just don't realize it, so I'm really no help in the matter. Most of the information ( don't know how accurate ) comes from a 2016, Ben Affleck movie, The Accountant.

Well, you can pick it up at sea level, and carry it to the top of Mt. Everest if you wish. That's almost 30 000 ft, just 6000 ft shy of the height an airliner flies. Is that far enough for you ?

I don't know. They've gotten really good at covering their asses. By the way, this past weekend in Chicago, 85 shot, 24 dead, mostly young black males, but a few middle aged and a few women. Meanwhile the police were keeping an eye on the protesters, or even marching along. Just an example of what happens when no-one is 'minding the store', or the police is defunded. I have to wonder if a simpler answer, like getting rid of police unions, which protect the repeat offenders like D Chauvin, might be enough to rid police forces of the 'bad' cops. Might make the rest not feel obliged to protect the bad ones, and 'police' themselves.

And while we are picking on police forces ( well, D Chauvin, the murderer, was a policeman ), why are politicians, legislators and DAs getting a free pass ? They set up the system and laws, that allow for the treatment and prosecution of people, based on their skin color. Seems very hypocritical that they now jump on the other bandwagon, and blame police forces for enforcing systems/rules they themselves created. Typical political maneuver, blame someone else, and cover your ass so you can get re-elected.

You could, but SWAT units use military gear. I thought you were opposed to that ? But what about a simple domestic disturbance, where the husband is drunk and beating on his wife ? Have you ever tried to talk to a violent drunk ? The only thing you can do is forcefully remove them, until they've slept it off. This is just a proposal so far, and hasn't been voted on yet. If it does go through, I can see all the affluent whites moving to privately protected neighborhoods, while blacks are left in the disadvantaged, unprotected areas, and the situation will get even worse, not better. And if enough cities decide to follow suit, I can see fear, and need for protection, driving white voters to choose voting for D Trump again this November, as the self-billed 'law and order' candidate, and the world is stuck with D Trump another 4 years. ( hope he's too stupid to take advantage of the situation, in that case )

Its happening, INow. "The Minneapolis City Council on Sunday announced plans to disband its police department and invest in community-based public safety programs following calls from activists to ‘defund the police,’ in the wake of George Floyd’s death at the hands of a Minneapolis police officer." https://www.forbes.com/sites/andrewsolender/2020/06/07/minneapolis-votes-to-disband-police-department/#2be203145274 I sincerely hope they've thought this through. I would hate to see a mental health provider, or social worker, show up at an event like the 1997 North Hollywood shootout. https://en.wikipedia.org/wiki/North_Hollywood_shootout ( because a 'mob' of people always make thoughtful decisions )

More specific to the OP "Does it make sense to say that something is almost infinite? If yes, then why?" Limits approach a value, but never actually get there. And are a very useful mathematical tool.

I have. And the answer ( I gave myself ) is that education, about what is harmful and what is beneficial to society, is more useful than simply trying to ban everything that anyone considers harmful. I hope you didn't think I would have a different answer for myself. I guess if you choose to ignore the following part or if you are a stickler for detail ( guess an experimental Physicist would need to be ) And that is the reason for comparing their effect on UK schoolkids ( exposed to the statue ) and US schoolkids ( exposed to M Twain's works ).Not to you in the town square. I guess I'll be dropping this now; as I said, it really makes no difference o to me one way or the other. ( just don't ever come to take away my Mark Twain, and other American classics ) It seems the 'trees' of my posts are being argued against, while the 'forest' of my posts is being totally missed. But this is a discussion forum and I like to examine contrary points of view. Thanks for indulging me, and keeping it civil.

It would be interesting to find out whether the Nazi swastika, the SS logo, the Communist symbolism of Stalinist Russia, Maoist China, and Pol Pot's Khmer Rouge are also banned by NASCAR. I would think they probably are not. Most likely, because there is plenty of education about the evils these symbols represent; not so much about Confederate symbolism. So I guess you can go through life banning everything that anyone finds offensive, or you can educate people as to the bad, and good, of certain people, or organizations. ( I know you mentioned it as a separate topic, but I thought it tied in fairly well with my previous post )

No. The topic here was the Colston statue. Which was merged with the 3 year old Confederate monument thread. There are plenty of people who did good throughout history, who also did bad things. And sometimes whether something is good or bad changes, throughout history. It's very easy to pick and choose those few who did only bad things, as it is to choose the even fewer who did only good things ( are there any ? some question Mother Theresa, various Popes, Mohammad and Jesus ). The vast majority of people have done ( and do ) both good and bad during their lifetimes. I personally, don't have a problem commemorating the good that a person may have done, as long as there is education about the bad/offensive actions also. We are all human, after all.

I'm getting tired of repeating myself, and you're probably getting tired of me repeating it. If you ask 50 schoolchildren in Bristol who Colston is, and what he represents, you might have very few who'll tell you he was a slaver. If you ask 50 American schoolchildren about Tom Sawyer and Huck Finn they will all know exactly who you are talking about, and other characters in the stories. It is required reading in schools. So which do you think has more influence on impressionable, open minds ? And no, don't misread that, as me advocating for the removal of books which portray life as it actually was. I'm advocating ( actually, proposing, I don't feel strongly enough about it to advocate ) education, to go along with all symbols of the past, whether books, pictures, statues, or what have you. That is just my opinion. But if people feel like they are doing something about racism by tearing down symbols of the past, to make themselves feel good about the way they act now, who am I to argue or object.

And did the statue of Colston ever mention the slave trade he participated in ? Did it glorify or defend it ? Most people don't even know who he is, or what he did/didn't do. I couldn't care less if his statue is removed. Nor Confederate monuments. But there was talk, in Canada of removing monuments of J A MacDonald, and renaming schools/buildings. And don't there aren't already people discussing the banning/modification of certain books, because, although they portray the times accurately, they offend today's sensibilities. I don't know if you've ever seen the movie Blazing Saddles, which, although a comedy, did have a 'message'. Do you seriously think that movie could be made today ?

I thought I had... They are both 'reminders of past events/way of life. And I stated ( opined ? ) that In my opinion they both provide information about past events, but books even more so than monuments ( which are largely forgotten ). Why would you want it to stop? Don't you want a better world? I'm not sure I understand you... Are you advocating for banning/re-writing books which present uncomfortable reminders of our sordid past, as well as monuments/statues ? I don't have a problem with removing monuments/statues. But I do have a problem with banning books. So, I asked, where does it stop ?

Perimeter is a one dimensional attribute, while area is two dimensional. IOW, you need one piece of information for one and two for the other. That allows for considerable ( infinite ) variation.

Master is the original from which copies are made. Along the same lines, you might have better luck with the internal platter of an old hard drive. They are very smooth and reflective, but extremely brittle ( possibly glass ), so cutting a small piece might be a problem.

Did not know this, but a lot of disinfectant gels use ethanol, not methanol or isopropanol. As a matter of fact, a whole lot of disinfectants recently got recalled because they used industrial grade ethanol instead of food grade ethanol. What, are people drinking the stuff now ?
