Comparing Corona Virus Success Stories with Abysmal Failures
Best strategy is stay at home if you can. And if you find yourself weakening, watch old movies like The Andromeda Strain, The Satan Bug, Contagion, 28 Days Later, Outbreak, 12 Monkeys, I Am Legend, or even Rise of the Planet of the Apes, to motivate you.

Corona virus general questions mega thread
Not everyone who is infected is hospitalized. Most people who are infected experience mild symptoms and need to self-isolate. The ones who do get hospitalized are the elderly ( over 70 ) and those with pre-existing medical conditions which have compromised their immune systems. Not all 60 million people need to be cycled through the hospital system. The problem is, Italy has one of the oldest populations ( more people over 65 yrs ) compared to other countries in Europe. But other countries are starting to catch up to Italy. Switzerland and Spain are very close; but for some reason Germany is an outlier of the data set, with much lower infection numbers. edit: corrected Spain, not France

Corona virus general questions mega thread
There's always 3% Hydrogen Peroxide, or a 5% Hypochlorite solution made from household bleach and water, Stringy. What purity IPA are you buying anyway ? Standard drug store stuff is only 50-75 % IPA. ( AKA rubbing alcohol )

Political Humor
No, no, no... The quote is "I’m funny how, I mean funny like I’m a clown? I amuse you? I make you laugh? I’m here to fuckin’ amuse you? Waddya mean “funny”? Funny how? How am I funny?" Joe Pesci, as Tommy, in Goodfellas to Ray Liotta, as Henry.

Debt-free College (Yang's Plan) - Split
Thanks for the info, INow. ( what can I say, I'm lazy ) Two Canadians in his corner might be seen as some kind of 'collusion'. Besides, I've always liked E Warren.

I think HE was a cross-dresser. Not that there's anything wrong with that.

Only 10% of the Nobel prize winners are atheist ?
Religious beliefs are based on 'faith', which requires no evidence or facts. Science is based on evidence and facts, and some people are more adept than others at determining/discovering that evidence or building models that attempt to explain those observations. On the other hand, sometimes being truly exceptional ( as Nobel prize winners are ) requires a 'leap of faith'. does that maybe explain how the two correlate ? ( I don't know, I'm just making this stuff up as I go )

"Wait a carrot-picking minute...
Some of the best memories of my youth ( early 70s ) are of Saturday evening dinner. Me and my brother would prepare supper after school, always chicken and potatoes in the oven ( only thing we knew how to make ), and my mother would make a quick salad when she got home from work at 5 pm ( we had just immigrated to Canada a few years earlier ). The best part was, that we didn't have to eat at the table on Saturday evenings, but could eat in the living room while watching 'The Bugs Bunny/Road runner Hour'. Oh, and re-runs of 'Star Trek' at 7 pm. ( first episode I ever saw was 'Who Mourns for Adonis' with the 'God' Apollo )

What are you reading?
You're going to the Mediterranean for two weeks and you're gonna read ??? Greece isn't it ? I can think of much better things to do. ( grilled octopus, Ouzo, and seeing all the little islands by boat and scooter )

A fine example
Despite being aesthetically pleasing, I don't find it thought provoking, or inspirational. IOW I don't get it. Then again, I'm a simple kind of guy

Youtube channels on science?
Don't watch many. But of those I have watched, the PBS Digital Series stand out. They are 'professional' in production as well as content, and not as 'dry' as a lecture. They manage to keep my interest even on topics I'm sufficiently familiar with.

Landing on a black hole!!
A radial trajectory WILL take you straight in. Its like an orbit through the center of the Sun. You're NOT coming out the other side.
-
Landing on a black hole!!
What did you have in mind... Every city would have its own geosynchronous orbiting, artificial miniature Black Hole to be used as a garbage dump ? They'd have to put up a tall fence around it. Anyone falls in; there's no getting them out. As for 'landing' on a Black Hole, what would you land on ? There's nothing there. Our best theory says the event horizon is a mathematical construct, and the central singularity is a dimensionless point.

If I can imagine it, it is possible!
I could have sworn G Cantor used the terms 'denumerable' and 'non-denumerable' for countable and uncountable infinite sets respectively. I stand corrected. However the definition you use for 'absolute' infinity is certainly different from his, and even more so from later work by B Russel and J VonNeumann.
-
If I can imagine it, it is possible!
Hmmm... I don't recall G Cantor ever using the term 'Absolute Infinity'. If this is your own personal definition, maybe you should actually provide proof that it exists. ( as Georg did with his proofs of degrees of infinity )
-
If I can imagine it, it is possible!
What do you mean ? There is an infinity of decimal places between 0 and 1. But, getting back to the cookies... They are NOT impossible. This website hands them out every time I log on. ( although they leave a bad taste in my mouth )

Gun control, which side wins?
Phi said... "We're used to tightening our belts/going to extremes in times of emergency" I think the gun related death rate in the US is an emergency. ( never mind the illegal immigrants at the southern border )

You would think they would standardize on one side or the other. If only to avoid the confusing messes at the gas pumps.

What is Space made of?
Space is simply space. It does not need to make a choice. WE need to make the choice as to which model we use, as the models used by GR and QT are currently incompatible. Perhaps I wasn't clear with my previous explanation... In QT, we can assign a co-ordinate system to a certain volume. That co-ordinate system is absolute and immutable. Quantum events happen on the stage of that co-ordinate system. In GR we can also assign a co-ordinate system to a volume ( more specifically volume with an orthogonal time dimension ). Yet that co-ordinate system is affected ( curved ) by mass-energy distributions within it. It is not absolute, and in effect, becomes part of, and modifies events. Romeo22 implies that space can only be one of the choices, the other must be wrong. He is confusing the models we use, and which have specific areas of applicability, with the reality. But he is correct in stating that the models of GR and QT use a different paradigm. ( and so we wait for Quantum Gravity to unify the two )
-
What is Space made of?
Quite right. It is more explicitly stated as GR does not require a background 'stage' on which events happen. The stage is considered part of the events, and is not absolute. ( note that this is space-time, not simply space ) Quantum theory, on the other hand, does have an absolute background 'stage' on which events happen. GR and QT are formulated differently, and that is one reason for the difficulty in formulating a Quantum Gravity theory. SString theory relies on a separate 'stage' like QT, but LQG tries to preserve the 'stage' independence of GR. ( and that's why I prefer it )
