Neo, your interludes of Ballet are fun and interesting.
However, it seems like fiddling while Rome burns. Yeah, I guess I am on a downer today.
So much going on that is bad, and there is little or nothing we can do about it.
@SHIREHOME: Sure, things seem bad at the moment. But it’s important to keep things in perspective. Things could always be far, far worse. We all live in a time of wonderous wealth and technology. We have shelter and plenty of food. We have incredible medical capabilities, treating and outright curing diseases and ailments that bedeviled our ancestors, extending and increasing quality of life. We have instant access to near limitless information about the world around us. We can communicate to people instantly anywhere around the world.
Personally I’m not really much of a ballet fan but I’m glad Neo posts stuff she’s passionate about to add contrast to the relentless negativity of the daily news and to remind me that there’s still a lot of goodness in the world.
I have loved Swan Lake from the very first time I heard the music, in my tenth or eleventh year. it was only much later that I saw the ballet performed. It is not surprising to me that this review of the ballet would only mention the music after five minutes, but for me the music has always been more compelling than the dance.
Nonapod, yes we do have those things. But they can be gone in a heartbeat. Some already are going. Cost can put some of those things out of reach of the average person.
“However, I have little doubt that the constant drumbeat of anti-Israel propaganda in the MSM has reduced support for Israel;….”
And right on cue from Neo’s post from yesterday, today my D acquaintances on FB have announced the “genocide going on in Gaza by Israel”. Again, these are people if you met them for the first time you would never guess they would state such. But, I know they get all their info from CNN, MSNBC, etc. Brainwashing works.
…they get all their info from CNN, MSNBC, etc. Brainwashing works. — physicsguy
One of the stories on Fox News primetime last evening was the police shooting of a black man during a traffic stop in Chicago. On the one hand, I’m getting a little weary of all these “conservative outrage” stories. However, the video clips of the coverage from CNN and elsewhere were shockingly deficient.
Yes, the man died in a hail of police gunfire. Uniformly omitted, was the tiny fact that the violence began when the motorist opening fire on the police and emptied the magazine of his handgun. Unbelievable coverage. Literally.
Just to mess with them, you should post a link to an English Translation of the 1988 Hamas Charter and quote the part where Hamas celebrates the original conquest of ” Palestine” by Muslims. And then the part about Hamas wanting to destroy the Rotary Club and the Lion’s Club. Of course FB may censor that. And put you in FB jail. That is one reason I finally got off of FB was their censoring.
Fast internet at last! They installed Fiber Optics today. WiFi calling worked and plenty of Ethernet connections on their modem. If it holds steady I’ll cancel the Verizon WiFi internet. Over 100 Mbps (12.5 MB/s) down loads and over 90 uploads — they have 1 Gbps but I probably don’t need that speed… 🙂 🙂
Personally I’m not really much of a ballet fan but I’m glad Neo posts stuff she’s passionate about to add contrast to the relentless negativity of the daily news and to remind me that there’s still a lot of goodness in the world. “
I agree. I just wish that she were more interested in fighter aircraft, internal combustion engines, firearms, hunting, and whiskies. To mention just a few.
Or that there wes even such a thing as a sliding sleeve valve auto engine. Something I only discovered after looking up the nameplate in the old family photo of young kids standing behind a car. [ a , Willys-Knight] .
Nonetheless, pretty good job Neo. You cannot be expected to be everywhere and into everything.
I guess that’s why we have Ian, and Jay and ….

DNW…”Then I would not have had to discover for myself that there were two types of early radial engines – one being a rotary radial with a stationary crankshaft. ”
Seems like a weird way to do things….I believe one advantage was better cooling…but centrifugal force meant that the airplane would turn much more readily in one direction than the other, which the pilot had to account for tactically, and his opponent could exploit.
There’s a lot of commentary about ‘elites’, almost all of it negative, but the term is rarely defined. I attempted to unpack it here:
Rotary engines were common in World War One aircraft. Radial engines came after. Have to think the gyroscopic effect of the motor whirling around at 2000+ RPMs must have been tremendous.
As they say, from the writer’s lips to God’s ear. From far left vanityfair magazine. Edit. It is not the first time that the Democrats’ lawfare is benefiting Trump.
Inside the Terrifyingly Competent Trump 2024 Campaign
“With Donald Trump mostly focused on his own legal peril—leaving staffers free to run the campaign—the candidate’s third bid for the White House is as efficient as it is explicitly authoritarian. How worried should you be? Very.”
During WWII, US Navy Warplanes were all Radial. Not sure why, maybe to save space on the Carriers. I friend of my Dad’s going back to WWII, was Mech on such planes. He said their was so much torque on the Corsairs that they had to jam the rudder to one side (don’t remember which side).
Yesterday, there was a tracked tank like vehicle on my one lane gravel road laying fiber. Left a big loop in my yard. Note there are only 5 houses on my road. My dog wanted to kill that machine. From 20 yards away though safely inside the fence. All bark, no bite.
I’m struck by how beautiful those two dancers are, and I’m not talking about just on stage. I love seeing them talk about their art; they light up. And of course, her gestures as she describes the story…. I think I could watch her sit on a folding chair and tell stories all day.
Bob Wilson…I’d like to see a lot more of that ‘terrifying competence’….email and direct-mail marketing I’m seeing from Repubs is pretty pathetic. Also, there is no attempt to engage on social media, it’s all one-way communication, the people doing this must think it’s the 1980s or earlier.
Also, of course, the line about ‘explicitly authoritarian’ is preposterous, especially when compared with the authoritarian and even totalitarian behavior of the Biden administration and the Dems in general
Re: Ballet
I’ve made worse mistakes, but I never got ballet at all until recently.
Thanks, neo!
I am aware that many find Tucker Carlson’s migration away from establishment conservativism toward whatever it is he now embraces, suspect, annoying and outright ideological and moral malfeasance, by means of both comission and omission.
Now, think what you will of the conclusions she draws and her personal and recent transformation. What shocked me to my core was an admission which both she and Carlson made: that they had never until recently actually read or attempted to read the Bible through, even as history or literature; despite as they both noted, their expensive and elite educations. [not to mention their strong cultural and moral social critiques which basically formed their business models.]
Now, I happen to know based on their self-admissions, that very many secular leaning Jews have never actually read the Torah, and basically mostly imbibed the Talmud second hand and as delivered in the liberal synagogs. But in her case it shocks me. Same with Carlson.
It reminds me of A.J. Ayer’s staggering admission that he was unprepared to teach a course on Plato because he had for the most part never read him and therefore had to play carch up on something so basic to and defining of the canon of western philosophy.
Effen eh, man.
“The Road,” a film based on a grim post-apocalyptic Cormac McCarthy novel, devastated me. I was moved to read the novel and background material. The book was partly based on conversations McCarthy had with his son, imagining a brutal possible future ahead.

Foster:
“… centrifugal force meant that the airplane would turn much more readily in one direction than the other, which the pilot had to account for tactically, and his opponent could exploit.”
Despite having seen numerous old movies of Spads or whatever trundling along for takeoff with rudders puzzlingly off at an angle, I never gave it any sustained thought.
It took an old Thunderbolt pilot friend of mine who was at retirement age as I was starting out to say and surprise me with a “Yes” as we sat in a bar avoiding the rush hour after work one day; and, I idly asked – thinking I must be missing something- if the rotation of the prop did not affect directionality. “Oh! It does?”
Turns out I had no understanding of how an airfoil actually produced lift either. No, you are not sledding through the air. He quickly sketched it out for me.
I guess that is what cocktail napkins are for.
Neo – I enjoy that you deal with a variety of topics on your blog. Your posts on dance, music, trends on clothing and words are a refreshing break from the anxiety produced by the many political stories.
And… for a non-political link…. Remember that 4.8 quake near NYC that dominated some of the national news? It seems that there has been 50 quakes in that area since 4/5.
The quake map of the US has been active in the last month, including my state of Oklahoma. I haven’t felt/heard anything in the last few days, but I have noticed a slight increase in Tinker AFB activity.
I’m not sure why you’d be surprised at Wolf not reading the Torah if she is a secular Jew only. I think Carlson is more surprising because as far as I know he’s long been a somewhat religious Christian.
I suppose you might be upset at anyone saying he or she hasn’t read it, since even for the non-religious it’s an important and influential book culturally. But surprised? I don’t see why one would be surprised at non-religious people not having read it, or having read just bits and pieces.
So glad it is spring. Just removed a bird trapped in the wood stove. Ugh. At least this one flew straight out the open door.
RockMeAle:
Yes, those two are very attractive, and what’s more their movements even off the stage are very graceful. That’s not always the case with ballet dancers, but it usually is.
” I suppose you might be upset at anyone saying he or she hasn’t read it, since even for the non-religious it’s an important and influential book culturally. But surprised? I don’t see why one would be surprised at non-religious people not having read it, or having read just bits and pieces.”
It’s a form of professional misfeasance, malpractice or at the least fraud or posing for a purported social commentator, or anyone who attempts to speak knowledgebly on the topic of our social mores, to not know the foundational texts.
I extended that analogy by citing Ayer’s admission in his autobiography.
As you know, it’s a matter of indifference to me insofar as it concerns their eternal fate, should they have one.
“We strongly recommend that Russian citizens refrain from traveling to the region, especially to Israel, Lebanon, and the Palestinian territories, except in cases of extreme necessity,” it said.
Russia said the security situation in Jordan remained stable.
To the ‘armchair lawyers’ who say the verdict in the so-called ‘Trial of the Century’ was a miscarriage of justice, I simply say: you don’t understand the law.
In the American justice system, guilt is not determined by the subjective morality of the public, but by the objective presentation of evidence and the establishment of proof beyond a reasonable doubt.
Furthermore, professional ‘splatter analysis’ showed the blood could have been poured on the sock while it was lying flat, rather than having been sprayed on while it was being worn.
(NOTE: Dexter Morgan was called in for this one…)
LAPD racism was a fact of life for people living in Los Angeles at the time.
The second most significant piece of evidence in the trial was the blood-stained glove – allegedly found by LAPD detective Mark Fuhrman at OJ’s estate – which matched a glove found at Nicole Brown Simpson’s home.
That ‘proof’ was compromised both by the emergence of recordings of Fuhrman using racist slurs and, most crucially, by the prosecution’s own blundering.
I was sitting near the defense team table when OJ walked up to the juror box and struggled to fit the glove over his hand, remarking ‘it’s too small.’
Not only did that pivotal moment give the jury another reason to question to veracity of the evidence, but it eliminated the need for OJ to take the stand in his own defense.
But back in 1995, the jurors heard the case as I have described. So, I’d ask all those who say the verdict was a miscarriage of justice: would they have convicted a man based on faked evidence?
A National Geographic film crew was visiting Atka Bay on the Ekstrom Ice Shelf, when they spotted approximately 700 emperor penguin chicks gathering at the edge of a cliff.
To their amazement, the chicks began to leap from the summit, before smashing into the icy ocean waters below.
Thankfully, the chicks emerged from the stunt unscathed.
DNW. et al,
The Corsair, and other WW2 planes had very large propellers which at full power produced a large torque needed to be countered by opposite rudder input.
On lift, there’s still this huge misconception of lift coming from Bernoulli pressure difference on the wings upper and lower surfaces. It does contribute but only on the classic airfoil. By far lift is mainly produced by changing momentum of the air due to the wings angle of attack. Don’t believe me? Then explain how a plane with a symmetrical wing (F104 for example) flies, or how a plane with a classic airfoil flies inverted using Bernoulli.
Re: Tucker Carlson
I don’t attend to Carlson regularly. However, I did look up his wiki bio and his early years are unusual.
_________________________________
Carlson was born Tucker McNear Carlson at the Children’s Hospital in San Francisco, California, on May 16, 1969. He is the elder son of Lisa McNear (née Lombardi; 1945–2011), an artist from San Francisco, and Dick Carlson (1941–), a former “gonzo reporter” who became the director of Voice of America, president of the Corporation for Public Broadcasting and the U.S. ambassador to the Seychelles, and more recently a director at the lobbying firm Policy Impact Strategic Communications….
There’s more. For instance, Carlson’s father married an heir to the Swanson frozen food empire.
TLDR: Carlson is an odd fellow juiced into elite levels of power and is going his own way, I guess.
A small sample, admittedly. Those who show the least benefit from their college degree are most concerned with its lack in others, particularly those who support Trump.
Talked to a guy who flew Corsairs in WW II and F9F in Korea.
About the torque. Wings on single-engine planes are not “equal”. That is, the wing on the side of the Corsair toward which torque would roll it has more lift built into its design than the one on the opposite side. This evened out the necessary positions of the control surfaces. If you have to crank all the way to the right to fly straight, you can’t turn right.
And, said my late friend, that was not an issue with the F9F (Panther, I believe), having a jet engine on the centerline.
I asked a couple of professional civilian pilots what would happen if there were four blades instead of three on the single-engine plane in their shop. “Roll right over,” they said.
Sleeve valves instead of poppet valves had been around since the 1930 and by the end of WWII were highly developed by Napier in Great Britain, Sir Harry Ricardo demonstrated (by maths) that a sleeve valve system would breathe better than a poppet valve engine (higher power, greater volumetric efficiency). The British had radial and in-line air cooled and water cooled sleeve valve aircraft engines. Then the gas turbine made them all obsolete within 10 years.
Anyway in 1974 during the first oil crisis Road and Track magazine had an interview with Mike Hewland (Formula I auto racing engines and gearboxes) claimed to have made significant progress on sleeve valve engines (for automobile use). Never came to pass.
My favorite version is still that gay troop who clomps around like a herd of elk on tiptoe.
Hard to be en pointe when wearing clown shoes?
there is a run on clown shoes,
I initially didn’t like Tucker, his proposal for what would become the daily caller, struck me as over the top, when he announced at cpac,
hes an iconoclast who like my namesake, has taken perhaps too many jabs at ponderous people,
I mean look at Adam Kinzinger’s sad panda pout, but he’s not merely stupid hes evil although when he hangs around with the head of the Storm Brigade, he bridges that gab,
Rush’s grandfather was ambassador to India, if memory served, but he’s not that much into decorum, well the whole Galbraith clan are fools and or knaves, the youngest son, who made out like a bandit in oil contracts in Kurdistan, as a sherpa to Biden, well which does that make one,

The cross section of the airfoils my old fighter pilot friend sketched out on a coctail napkin did indeed as you intuited show the same flow and force lines you refer to and which we have now become accustomed to seeing in presentations on the history of heavier than air powered flight.
Special attention has often been paid to this by historians with regard to the work and wind tunnel discoveries of the Wright Brothers concerning previously available data.
So, so far as the early days and the design, control, and the power to weight ratios possible at the time, I assume that you have no problem with the principle at that stage. Or, maybe you do.
Now, my cocktail napkin and old History Channel education in aeronautics has not continued to modern [mid century and later] jet and rocket powered aircraft, but I am aware that it is said that many modern planes and especially stealth aircraft “should not be able to fly”.
One even wonders exactly how an F 104 managed it, its wings not exactly having a classically obvious teardrop upper surface profile.
And even a civilian sees phenomena such as that speeding cars may tend to lift off the ground, or that a flicked playing card may rise if edge angled up, even if the principles involved are not understood or even the same category of phenomena. So clearly there are more ways to skin a cat than one given certain conditions and resources. Whether you could actually “surf” through the air under controlled flight without computers, I have no idea.
With enough thrust you can make a brick fly.

I don’t attend to Carlson regularly. However, I did look up his wiki bio and his early years are unusual.
_________________________________
Carlson was born Tucker McNear Carlson at the Children’s Hospital in San Francisco, California, on May 16, 1969. He is the elder son of Lisa McNear (née Lombardi; 1945–2011), an artist from San Francisco, and Dick Carlson (1941–), a former “gonzo reporter” who became the director of Voice of America, president of the Corporation for Public Broadcasting and the U.S. ambassador to the Seychelles, and more recently a director at the lobbying firm Policy Impact Strategic Communications….

There’s more. For instance, Carlson’s father married an heir to the Swanson frozen food empire.
TLDR: Carlson is an odd fellow juiced into elite levels of power and is going his own way, I guess.
A small sample, admittedly. Those who show the least benefit from their college degree are most concerned with its lack in others, particularly those who support Trump.
Talked to a guy who flew Corsairs in WW II and F9F in Korea.
About the torque. Wings on single-engine planes are not “equal”. That is, the wing on the side of the Corsair toward which torque would roll it has more lift built into its design than the one on the opposite side. This evened out the necessary positions of the control surfaces. If you have to crank all the way to the right to fly straight, you can’t turn right.
And, said my late friend, that was not an issue with the F9F (Panther, I believe), having a jet engine on the centerline.
I asked a couple of professional civilian pilots what would happen if there were four blades instead of three on the single-engine plane in their shop. “Roll right over,” they said.
Sleeve valves instead of poppet valves had been around since the 1930 and by the end of WWII were highly developed by Napier in Great Britain, Sir Harry Ricardo demonstrated (by maths) that a sleeve valve system would breathe better than a poppet valve engine (higher power, greater volumetric efficiency). The British had radial and in-line air cooled and water cooled sleeve valve aircraft engines. Then the gas turbine made them all obsolete within 10 years.

Anyway in 1974 during the first oil crisis Road and Track magazine had an interview with Mike Hewland (Formula I auto racing engines and gearboxes) claimed to have made significant progress on sleeve valve engines (for automobile use). Never came to pass.

Regarding torque and the 2500+ HP piston engine propeller airplanes, one solution was coaxial contra rotating propellers. Or well trained sane pilots?

Ballet is probably of much more interest to most.
My favorite version is still that gay troop who clomps around like a herd of elk on tiptoe.
Hard to be en pointe when wearing clown shoes?
there is a run on clown shoes,
I initially didn’t like Tucker, his proposal for what would become the daily caller, struck me as over the top, when he announced at cpac,
hes an iconoclast who like my namesake, has taken perhaps too many jabs at ponderous people,
I mean look at Adam Kinzinger’s sad panda pout, but he’s not merely stupid hes evil although when he hangs around with the head of the Storm Brigade, he bridges that gab,
Rush’s grandfather was ambassador to India, if memory served, but he’s not that much into decorum, well the whole Galbraith clan are fools and or knaves, the youngest son, who made out like a bandit in oil contracts in Kurdistan, as a sherpa to Biden, well which does that make one,
The cross section of the airfoils my old fighter pilot friend sketched out on a coctail napkin did indeed as you intuited show the same flow and force lines you refer to and which we have now become accustomed to seeing in presentations on the history of heavier than air powered flight.
Special attention has often been paid to this by historians with regard to the work and wind tunnel discoveries of the Wright Brothers concerning previously available data.
So, so far as the early days and the design, control, and the power to weight ratios possible at the time, I assume that you have no problem with the principle at that stage. Or, maybe you do.
Now, my cocktail napkin and old History Channel education in aeronautics has not continued to modern [mid century and later] jet and rocket powered aircraft, but I am aware that it is said that many modern planes and especially stealth aircraft “should not be able to fly”.
One even wonders exactly how an F 104 managed it, its wings not exactly having a classically obvious teardrop upper surface profile.

And even a civilian sees phenomena such as that speeding cars may tend to lift off the ground, or that a flicked playing card may rise if edge angled up, even if the principles involved are not understood or even the same category of phenomena. So clearly there are more ways to skin a cat than one given certain conditions and resources. Whether you could actually “surf” through the air under controlled flight without computers, I have no idea.
With enough thrust you can make a brick fly.
