What is the newest installment of 'Random Thoughts' on Physics Forums?

Karen

boingboing

 

[fresh_42]

Ken is more associated with Barbie. Perhaps Barney is better.

It's not our choice. I've seen Ken on social media.

 

[jedishrfu]

Yeah, I just saw that with the American Girl photo above so it makes perfect sense.

I picked Barney because of the Mayberry RFD character of the bumbling deputy who was always trying to impose the letter of the law no matter how minor the infraction.

It is Kevin and double names which have a bad reputation here, but more in the direction of being silly, rather than "patridiots".

 

[WWGD]

Somehow all are names starting with K: Karen, Kevin. Ken.

Here's the VOX take on the Karen phenomena:

Id like to speak to Greg?

Looks like Fresh is requesting a crew change that is out of service due to intoxication in aisle R.

Wonder if there are versions of Karen in other languages or maybe in UK, other English-speaking countries.

I doubt that. The phenomenon is purely American and to be honest, not existing in other countries. We others prefer to treat those people and not letting them run wild, let alone carry guns. There are some fetishes which you can find only in America: anti-socialism (where socialism already starts by offering someone a free drink), liberty (which you only have if you are rich), flag and hymn (cover instead of content), guns, no healthcare. None of them can be found anywhere else in a western country.

And clearly, questionable statements from the far left.

Well, that is my impression. And what is far left in the states is center left here. But that was exactly what I meant. The American fear from the s-word is stronger than anywhere else. So strong that it starts at points which others consider normal.

I can't imagine what the statues in Germany are going through.

I.M. Nick was president of the American Name Society?

I.M. Nick was president of the American Name Society?

You know her?

 

[Keith_McClary]

You know her?

Only by her nickname.

 

[jedishrfu]

I think she was a student of Dr A. Tomic, professor of memeology at the University of Da Hills.

I just saw a short interview with Liam Neeson.
I didn't know he was into physics, he even did an explanation of an experiment, I guess he likes physics:

I wonder what the minimal algebraic conditions are in an algebrsic structure A for a polynomial in A[x] to have at least one solution. Algebraic closure is overkill, but finite stru tures like, e.g. Zn don't have the property.

 

[fresh_42]

If any polynomial has at least one solution then you get algebraic closure, since you can always divide off that zero and proceed with the rest. Otherwise $A$ shouldn't be Euclidean, esp. no PID. If you allow non integral domains for $A$ things get weird I guess.

What do you do with , e.g., $(x+1)(x^2+1)$ over the Reals?

 

[fresh_42]

The point is, that you didn't pose any restrictions on the polynomials. So as long as you require that any polynomial splits, you get the entire package. The definitions in question are "normal and separable field extensions", but you didn't require a field. As I write this, I wonder what e.g. $\mathfrak{su}(n)[x]$ would look like.

 

[WWGD]

I understand, thanks, that I can always extend by an element of choice. But, short of knowing the structure in question is already an extension, is there a ready-made structure where this is guaranteed? Maybe not, don't see a reason for this to be the case.

 

[fresh_42]

... is there a ready-made structure where this is guaranteed?

Not sure what you mean by "this". There are universal objects or you can "tensor up" the scalars, e.g. from real to complex $-\otimes_\mathbb{R} \mathbb{C}$. Then there are (half) group algebras etc. An indeterminate attached to a structure is normally just a simple transcendental extension. Looking for zeros is asking for ideals.

But Galois theory is only one branch where those questions lead to. Others are algebraic geometry, complex analysis, K-theory, quadratic forms, elliptic curves or whatever. We need polynomials and their zeros even in linear algebra. Those damn things are everywhere.

Kind of weird response:
" Let's open up a restaurant".
" All restaurants around here are already open!".

 

[Keith_McClary]

They pay "journalists" to take a small table of numbers and expand it into thousands of words like this:

...
Newfoundland reported no new cases of COVID-19 on Monday marking three full days without a new infection.

The province has tested 20,583 people for the virus so far, and 258 have recovered from infections.

According to health authorities, a total of three people have died as a result of COVID-19.

Neither the Northwest Territories or Nunavut reported new cases of COVID-19 on Monday.

So far, the Northwest Territories has not seen any COVID-19-related deaths, and has tested 2,859 people for the virus.

A total of five people have recovered from infections in the territory.

And then they wonder why the traditional media are dying.

I know an academic (in biology) who is unable to makes heads or tails out of a 2 x 3 excel table (?$%#@&?).
Putting it in words can be helpful to some people.

Mi friend designed an app that uses a database and thinks he can avoid injection through login and permission restrictions only, without parametrizing queries. Doubt it will work out.

Very bright. Use a filter.

"Should we use discord ?"
" No, I prefer dat cord".

Where? How about if I mention the Sharpies of Jehova? ( Stones already coming my way. I am outta here).

Nobody is to draw a beard on anybody, even if they do say Sharpies!

"Romans go home" - the correct version. Brian originally writes "Romanes eunt domus" which John Cleese translates as "People called Romans, they go, the 'ouse" before giving a lesson in Latin grammar at swordpoint.

But apart from the Dead Parrot, the Ministry of Silly Walks, Fish Slapping, the Black Knight, the Spanish Inquisition, Monsieur Creosote, and the Killing Joke, what have bloody Monty Python ever done for us?

Want absurdity?
Just saw online images of protestors in front of a Starbucks:
We
Want
Just
Ice

And they're rioting just because they want ice? I like my drink cold, but I am not that hard core about it.

They made a three-sided album, The Monty Python Matching Tie and Handkerchief.

Spoiler: Three-sided??

When you played the second side of the vinyl disc, you would randomly hear one of two completely different sets of sketches. This would have come as a complete surprise to most listeners, as there was nothing on the label or sleeve to indicate what would happen. To add to the confusion, both sides of the disc were labelled "Side 1".

Spoiler: How was it done?

Two concentric spiral grooves, interleaved between each other, instead of the usual one.
