The REAL Reason Too Many Companies Can't Find Good Workers


Two recurring puzzles to do with the current job market are: 1) Why are so many job openings going unfilled? and 2) Why does wage stagnation remain entrenched?  It is also possible to inquire if the two are somehow related, i.e. are relatively low wages for certain jobs (e.g. STEM occupations, in science, technology, engineering, math) putting workers off applying for them?

In respect of (2),  Lauren Weber, in a recent WSJ piece, noted that a "global market" is one factor holding U.S. wages in check. In effect, factory workers in Pennsylvania compete for jobs not only with each other but also in China and Mexico where wages are lower. Nothing Trump has done up to now has changed that in a significant way.

Weber also investigated why so many companies are having a difficult time filling their openings.  What she found was the "companies are reluctant to raise pay, in part to protect their profit margins".  They also prefer right now to have more money set aside to buy back their own shares if it can help their bottom line, increase share prices.

According to managing director of Aspen Advisors, Andrew Gadomski, that is "holding back hiring".   He notes that when companies lament they can't find workers to fill key openings, that is code for: "I can find talent, I just don't want to pay them as much as they cost."

In other words, these employers are quite capable of finding the workers with the background they need, they just don't want to pay them what they are worth.  Well, what's an employee to do? The answer is to either stay out of the cheapskate job market until employers shape up, move to another location to find a similar job, or perhaps look at changing skills, professions. (Though there is no guarantee the same cheapskate bosses won't dominate other areas too)

Note also that this is despite job openings being at "all time highs" according to Beth Ann Bovino, chief U.S. economist for S&P Global Ratings. Thus: "Businesses are struggling to fill these positions in an increasingly tighter market." As per a Denver Post article highlighting the situation ('Sounds of Silence Greet Colorado Employers Looking for Summer Help', June 11)::

"Steve Homolka needs to hire just five workers this spring to help him with his family masonry-staining business.Finding them has proven much more difficult than he ever imagined. And it isn’t about unqualified applicants. Nobody is responding to the numerous ads he has posted on Craigslist, Facebook, Instagram and other sites."

Thus, it appears that there is a surfeit of positions but not enough takers. But why aren't there takers? Is it that the qualified employees don't exist, or not enough, OR is it because the companies aren't prepared to pay a proper remuneration? In the Colorado example cited above, it may just be that summer work is an insufficient lure and people (e.g. college grads) want something a tad more long term to be able to move out of the family basement.

In the more general context employers may simply be cheapskates and unwilling to part with good money for good talent, whatever the job.  This is apparent given the remark ("I just don't want to pay them as much as they cost.") of the employer cited by Andrew Gadomski.  In other words, the companies have brought this situation on themselves.

Adding to that is what employers often view as a labor shortage is in reality a retention problem, this also according to Gadomski. Obviously if you are losing workers - chasing better pay or benefits - you have to replace them. This is especially the case now when employees are willing to jump ship for a raise after many years of being expected to work harder - but getting only ulcers and overtime offers for their trouble.

Again, it is evident that the companies have largely brought their predicament on themselves.  To substantiate that, Weber reports that "workers are voluntarily quitting jobs this year near the highest rate since the recession ended".  This according to Labor Department data.

While the stinginess of employers could well explain the lack of openings filled in skilled occupations, e.g. STEM jobs (in Colorado last year there were 15.3 openings for every potential candidate), this may not translate to the lower wage domain.   Here, the attacks on immigration and immigrants by the Trumpies could account for labor shortages in agriculture, for example. An open question in the vast agro fields of California and Florida is 'who is going to pick the produce now?'   The working class unemployed white Americans aren't prepared to go into the fields, so who will?

Similar labor shortages apply in landscaping as well as construction with thousands of jobs going begging here in Colorado alone. The unemployment rate in CO is currently 2.3 %, the lowest in the nation. In metro Denver, labor markets are even tighter, with the unemployment rate dropping down to 2.1 percent.  Much of this has been on account of an influx of over 20,000 millennials to grab any jobs they can in the banking, energy, or MJ sectors.  The problem is that these newcomers have basically left the door "closed" for others unless they want to take a seasonal- only job. (See above)

Meanwhile, as  Trump's crusade against immigrants, especially Hispanic, continues - the lower wage labor shortages are likely to reach crisis level.  To give an example - as cited by Lauren Weber- the scale of the problem is already such that some growers, e.g. in CA, FL, have discarded portions of their harvest. They have no choice if they are unable to get the workers to do the harvesting.

Added to this, temporary workers across the board are more consistently demanding higher wages and full time work. This according to Rachel Chapman, owner of a staffing office in Huntsville, AL. The problem is that most of her clients can't afford to pay the $12 /hour now demanded.

What seems ever clearer to me is that employers who could formerly pick their workers at their leisure and fire them for the slightest infraction, will now have to vigorously compete to fill positions. That also means paying them what they are really worth instead of stiffing them.

Conservative Knuckle heads Protest "Julius Caesar" Play In Park - Prove They're Hypocrites and Pro-Censorship

The Public Theater's Free Shakespeare in the Park production has caused controversy 
Scene from 'Julius Caesar'  in Shakespeare in Park performance. Idiot Trumpies who rushed the stage can't tell fiction from reality.

We are in parlous times indeed when morons of the Right are unable to even parse reality from a fictional play and actors from actual personae. And so it was several days ago conservative lamos tried to interrupt the current Shakespeare in the Park performance of Julius Caesar because they believed it was portraying the "assassination" of their scumball hero prez who loves to grab pussies and insult the disabled.

The bimbo who did the main interruption later identified herself on social media as Laura Loomer . This half wit had jumped onto the stage just after the assassination of Caesar and began shouting, “Stop the normalization of political violence against the right,” and, “This is violence against Donald Trump.” Ms. Loomer described  herself as a “a right-wing investigative journalist and activist” who has previously worked with James O’Keefe, the guy who loves to confabulate false news using edited videos.

Subsequently,  her compatriot emerged shouting  to the crowd: “You are all Goebbels,” a reference to the Hitler aide and Nazi propagandist Joseph Goebbels.  Again, this sorry fool unable to distinguish a genuine Nazi piece of filth from a crowd who's merely gathered for some free entertainment. He really needs to go back to his meds, or ECT.

On social media,  this looneytune - Jack Posobiec-   describes himself as an activist who supports President Trump and has been associated with conspiracy theories, identified himself as Ms. Loomer’s collaborator. Well, nuts of a kind are equally blind.

Loomer, however, is little different from the odd knuckleheads who dispatched tweets to 'Fox n' Friends' this a.m. with such stellar observations as ; "The Left must stop killing our POTUS!"  And, paying a genuine tribute to free speech and artistic independence: "The Left must learn it has to temper what it says and does".  Oh really, you asswit? Like you do when you screech about the Left denying Anne Coulter a speaking gig? Gimme a break!

The earlier tweet about "killing our POTUS" shows how fucking dumb these fools are, they can't even tell a play from reality. But it's no surprise given how they indiscriminately gobble up fake news. In fact, no one is being "killed" as it's a play with actor Gregg Henry (of "Rich Man, Poor Man" fame) playing the role of Julius Caesar. That he might happen to look slightly like the Donald doesn't make him the Donald.  A point that shouldn't need repeating but to people who can't tell fable from fact it does.

Other deranged half wits attempted to disrupt the final performance yesterday. One protester, Jovanni Vale, even stormed the stage and shouted “Liberal hate kills” before being quickly grabbed by security, according to the New York Daily News. Soon after, Salvatore Cipolla did the same while yelling “Goebbels would be proud.”  No, asshole, the same Goebbels who oversaw massive Nazi book burnings would be proud of a loser like you it you managed to shut down the production!

What are more apropos remarks than the Right's squealing included New York Times theatre critic, Jesse Green, writing: “Its depiction of a petulant, blondish Caesar in a blue suit, complete with gold bathtub and a pouty Slavic wife, takes onstage Trump-trolling to a startling new level.”

Well, uh yeah, but let's not forget how the Trumpies  (not to mention Trump himself) trolled the rest of the country all the way through the 2016 campaign and then after.

David von Drehle in his TIME article ('Never Mind Trump, We Need Shakespeare More Than Ever', June 26, p. 17) was probably more on target when he pointed out that:

"With Trump in power, dressing a blonde actor in a long necktie and calling him Caesar is, for an impressario, as obvious as Wonder Woman 2"

He goes on to describe how and why the play so easily adjusts and adapts to different settings in space and time, because - there will always be tyrants, or wannabe tyrants, and they can always be made to come alive anew in the right casting.

Adding:

"Shakespeare would revel in the hypocrisy of Trump's shocked, shocked defenders".

Indeed. Because these nitwits are blind to their hypocrisy and how they enjoyed - not doing actual plays as artistic license- but straight out hanging Obama in effigy and claiming "free speech" e.g.
Image result for obama lynched images

Actor Gregg Henry  was quoted by the UK Telegraph:

"The Roman emperor became drunk with ego, drunk with power, drunk with ambition and the belief that he and he alone must rule the world. The idea for me was to try and show you that this could be Trump.”

Adding:

 “When a tyrant comes to power, it’s very important how you then try to deal with the problem - because if you don’t deal with the problem in a proper way, you can end up losing democracy for like, 2000 years.”

Ouch! Don't go there, Mr. Henry or the Reich's imbeciles will believe you actually are pretending to BE Trump!

Meanwhile, the unhinged freakazoids of the Right keep on with their petty victimizations. Though the  Times has been sponsoring the  Public Theater for over 20 years, and said they would continue to do so for reasons of artistic independence - the right wing website The Daily Caller published a story with the headline: "The New York Times is sponsoring an assassination depiction of Donald Trump."

Again, the historical and literary retards can't discern it's a depiction of the assassination of Julius Caesar in a modern setting, wearing suits instead of togas. Not Donald Trump.

If we are now going to allow the Right to try to enforce censorship of artistic productions, we are really in deep shit as a nation. Dick Cavett, when asked about his opinion by Ari Melber yesterday evening was blunt: "I'm against any kind of censorship. That's not what this nation is about."

But make no mistake, the weenies and hypocrites of the Right - after the shooting last week - will try their level best to use it to snuff out creative productions, as well as intense criticism of their agenda. The Left and Democrats must not allow this, and stand up to this lot each time they try to conflate fiction and reality.

Words from Shakespeare to remind us of the times we're in where too many can't discern reality from fable:

"Indeed, it is a strange disposed time:

But men may construe things after their fashion,

Clean from the purpose of the things themselves."

How Explain The Sad State Of Undergrad Physics Lab Teaching In U.S.?

Image may contain: 1 person, sunglasses, beard and indoor
Physics lab instructors mentored on how to set up and run a quantum optics experiment.

The news as reported in a recent issue of Physics Today (April, p. 26) was shocking to say the least. That is, that the state of undergraduate physics laboratory teaching in the U.S. is one of total disarray and economic disconnection. How bad are things?  Let's list them:

- Much of  the equipment is dilapidated and beyond practical use

- Experiments are not up to date, e.g. many school are still doing the Millikan oil drop experiment and Cavendish gravitational force experiment.  Many others are also decades or centuries old.

- Many schools are so impoverished in equipment they can't offer labs beyond the first year (mostly associated with General Physics courses)

- Funding for maintaining and updating labs is lacking, and note here that maintaining labs is time consuming and often requires knowledge beyond any one person's research experience.

- Faculty get scant credit for investing time in the labs, including jury rigging dilapidated equipment

The preceding betray the extent of an embarrassing problem that currently affects roughly 750 institutions including "elite" schools. In effect, among those schools that offer a physics bachelor's degree "there has been a collapse" in lab courses. This according to Illinois Weleyan University's Gabriel Spalding.

Given that physics is ultimately a practical science as much as theoretical, it was disheartening to read of the state of labs across the country. Given the university labs I've been associated with have all been thoroughly supplied it was difficult to conceive the basis for the downslide (But at the same time, I am referencing my last teach of labs some 25 years ago.)

What happened?

Basically this is really an economic question: how is it the money dried up to support undergrad labs including maintaining equipment? We have to go back to 1985 when the National Science Foundation (NSF)  established the Instrumentation and Laboratory Improvement (ILI)  program.  The ILI made matching grants available for lab equipment across many disciplines.

From 1985-95, according to program records, ILI awards were made to 1185 institutions totaling $158.6 million. The discrete awards varied from as low as $5,000 to $100,000.  Over time, however, the program became more educationally diffuse so initiatives that once focused on equipment alone expanded to broader educational missions. While the latter may well have been worthwhile, they siphoned money away from purchasing new lab equipment and maintaining existing equipment.   The end result was a zero sum game with the laboratory aspect getting the shorter stick over time.

Worse, a competition was set up within institutions pitting instructors needing physics education equipment against those wanting pure research equipment.    The NSF instructions for declaring need for grants  insisted on "being clear of the knowledge generating aspects" of the proposal. Basically, one had to choose between "physics education research" (i.e. money for lab equipment to teach students) or physics research per se needing equipment for specific experiments. As one prof quoted in the piece put it:

"If I want money for equipment, I don't want to do physics education research. If someone wants to do physics education research they don't want to approach an experimental lab the way I go about it."

The result? According to Gabriel Spalding:

'There really is no significant federal money for instructional lab equipment any more".

So we can afford to piss $3.1 b a month down the drain in Afghanistan for a "war" we can never win, while our universities - supposedly training the next generation of physicists -  go begging for lab equipment.

Fortunately, a decade-old professional organization: the Advanced Laboratory Physics Association (ALPhA), has stepped in to help reduce the problems facing undergrad physics lab teaching.  Their efforts have included: conferences, training sessions and other activities. Complementing these efforts, there is the company TeachSpin -created by Jonathan Reichart-  to promote and support undergraduate physics laboratory instruction.   Part of TeachSpin's mission is to disseminate new experiments, such as the one shown on quantum optics in the graphic, for more advanced lab instruction.  This has been enormously valuable in conjunction with ALPha's  'Beyond the First Year' (BFY) college lab conferences to showcase many new lab experiments.

But let's not kid ourselves here. While ALPha's and TeachSpin's efforts and contributions are laudable and important, they will still not be sufficient to sustain undergraduate lab teaching in the long run. For that, greater federal funding is needed, namely a reversion to the original ILI program sponsored by the NSF.

A Saturnian Moon That Looks Like Ravioli: PAN

Image result for EOS, Saturn's moon Pan
Two images of Pan taken by the Cassini spacecraft. At left is a polar view, i.e. taken from above one of its poles, at right is a lateral view with the bulging equator at an angle. The resolution of the (raw) images is 150m and the moon itself has a diameter of 35 km.

Who would have believed that the Cassini spacecraft, after entering a "ring grazing" orbit, would encounter one of the most peculiar moons in the solar system. While some have compared it to a flying saucer, other planetary astronomers have taken the more prosaic view of ravioli.  Whichever it is, even already awed specialists have to admit the sights of little Pan are mind bending.

It is precisely the close orbit of Cassini that has allowed it to get close up views of moon like Pan, orbiting Saturn at a distance of 134,000 kilometers. The new images, as shown in the accompanying examples, feature a resolution as fine as 150 meters, about the size of a football field and another half of field.

How did the peculiar shape come to be? According to Carolyn Porco - leader of the science imaging team for Cassini, it appears that as the moon coalesced from the debris of the early solar system, material from Saturn's rings fell onto the moon's equator and built up its disk like silhouette.   Porco bases this hypothesis on computer models using calculations of the likely dynamics for the material.

Thereby, over millions of years, Pan blazed a trail through Saturn's A  ring -clearing what is now referred to as the Encke Gap.  To be sure, the influx and accretion of material onto Pan's equator has decreased but plausibly continues to a lesser degree.  According to Porco, this is why the bulging belt looks smoother than the rest of the moon.

In an interview with Eos: Earth & Space Science News (may, p. 7) she added:

"Aside from just the sheer joy of seeing something so alien at such a level of detail  images like these will have an extension beyond the solar system."

In other words, studying the ravioli-like Pan will be especially helpful when planetary astronomers consider the processes and dynamics by which material accretes on a body with very low gravity.

If Repukes Want "Civility" THEY Need To Show Respect For Fellow Citizens and Laws First!

"I could stand in the middle of fifth avenue and shoot somebody and not lose any voters" - Donald Trump in a 2016 campaign brag.

See:  https://www.youtube.com/watch?v=iTACH1eVIaA



"Is it not perverse that we are united as one nation only when a national political figure is shot?

We are not united when 24 million stand to lose health insurance.  We are not united when the Earth is in environmental danger. We are not united when guns are used to carry out another mass shooting of innocents. We are not united in keeping Wall Street in check so it doesn’t wreck the economy again.

As horrible as this shooting was, any such unity is thin and fleeting."  Letter writer Peter Munger, in response to Denver Post editorial:  After Alexandria shooting, a reminder that we can still come together


Well, it wasn't long before the mass shooter of four people yesterday in Alexandria, VA was identified as a homeless man and likely disturbed Lefty named James T. Hodgkinson.  Hodgkinson, wearing jeans and a blue shirt, was wielding a rifle from behind a chain-link fence near third base. By most estimates, he fired at least 50 rounds, the bullets kicking up earth and gravel.  Pandemonium erupted as exposed GOP House members and aides dove into a dugout for cover, then raced into the dog park or jumped over a fence and ran for their lives.

When it was all over, House GOP Whip Steve Scalise lay critically wounded, and remains in that condition. And no sooner had the day ended than Right wing talking heads - including Newt Gingrich and Chris Collins, were yakking it up that it was all on the "Left" for its "extremist" rhetoric and "hyper partisan" behavior including yelling at reps in Town Halls. Meanwhile, House Speaker Paul Ryan - numero uno guy who plans to gut health care for millions - gave his best performance of how we "are united in our shock, we are united in our anguish" and need to come together since "an attack on one is an attack on all".  Stirring words, Paul, but what are you going to DO to prove you mean them, and also that your policies won't wreck the lives of millions?

At this point,  serious critical minds have got to step in and call bullshit on a lot of this empty, feel good palaver. We are going to debate for the next year or so the genesis of this attack and who was responsible, but let's cut to the chase very fast and say a lot of elements  - especially in the Trump domain - share much of the blame.  Rather than 'come together' as Trump first semi-advocated after the Nov. 8 election win, he's constantly sought to govern only on behalf of his looney, fake news followers while ignoring the 52 percent of the nation that never voted for him.

He's even openly admitted he's there only for "his people" so why the hell should anyone be surprised at the "hyper partisan" atmosphere engendered?   Meanwhile, even as constitutional norms and laws have clearly been flouted, now seeing obstruction of justice on the table, Trump's Republican party has played the game of "see no evil, hear no evil, speak no evil" and buried its collective head in the sand. The party has placed itself over country in the Trump -Russia investigation, and refuses to even concede Trump has done any wrong.  In effect, making a "deal with the Devil" and pretending such deal making can't have real world consequences, or if it does it ought to be ignored.

Then they talk, like Paul Ryan, as if this agenda and its derivative policies exist only in the abstract and won't tear asunder the lives of millions of citizens. The latter left without even basic health care if the Republicans' detestable AHCA goes through. And it's being done via stealth, in a final push behind Senate closed doors,  because the Repukes are too ashamed to let citizens know the actual sordid details of how it will destroy their lives if enacted. Well, after yesterday's events, they have good reason to hide it!  Look, if the bill was the least bit respectable and respected citizens, there'd be no need to keep it hidden.

What I am about is that words and actions via policy motivated legislation can also have consequences, which can be as brutal as bullets in the hip of a congress critter. When those parents who will be affected by repeal of Obamacare see their loved ones dying, including children of diseases like brain cancer, and leukemia, the "talk" policy aspect ceases and reality sets in. When people in 18 counties of Ohio, see their sons or daughters die of opioid overdoses because health care support funds  - including for narcone- have been eliminated, it gets real. The point? Policies have serious real world repercussions and you can't just expect millions to put them in an isolated cubicle and not make connections to WHO is responsible.

Was it justified then for someone like Hodgkinson - a Bernie supporter- to let his emotions out in a blaze of targeted gunfire? Of course not! The guy was obviously at an extreme tipping point including that he was barely existing in a homeless condition and held a grievance with the Repukes for that, not too different from how millions of Trumpies hold their own grievances, say at James Comey ("He's a coward") or Obama.

What I am arguing here is that there is an entire matrix of responsibility for what occurred in Alexandria yesterday and to lay the blame entirely on one lone, crazed gunman is to miss the point, as well as to miss fixing what is wrong with this polarized nation. Truth be told, one of the most powerful memes driving what's transpired, including hatred - yes hatred - of Trump, harkens back to his own words and behavior. That includes when he openly bragged he "could stand in the middle of Fifth Avenue and shoot someone and not lose voters."  If a now sitting president could have actually said those words, effectively endorsing the most extreme potential actions, why be surprised some of the most unstable citizens might take them literally, to heart?

Let's also not forget his own enticement of violent behavior at his rallies, where he actually encouraged Trumpies to punch out protestors, and even go after the media. Ah, but too many 'Muricans have the memory of gnats so it's easy to forget all Trump's antics, even after just 6 or 8 months.  But many of us haven't. Not because we're holding permanent grudges or "grievances" but because we wish to have a historical perspective capable of putting any current events into a larger context of cause and effect.

As to the current, post -incident outcries for "more civility", e.g.   at Town halls, that depends on congressional representatives. THEY have to share responsibility for shout downs when they refuse to respect their constituents'  voices and concerns, or frivolously dismiss them. Such as many people who expressed concern  over losing their ACA benefits and seeing their children in agony - say from a terrible cancer- because they're deprived of the critical treatments they need.

DO the Repukes make the connection between harm from their vile policies and extreme reactions to them? I doubt it. But until they do the polarization and antipathy won't cease and we will continue to roll on toward an actual second Civil War. As I wrote before, you simply cannot sustain for long two large segments of a nation that operate in two different realms of news, belief, science acceptance, policy etc.  Eventually,  unless those two factions synthesize,  they will come to blows, and we may well be seeing the first evidence of that, for example in the violent altercations between the Alt- Right and anti-fascists.

The likes of Gingrich and Collins blaming the "Left" without examining their party's own nefarious policies and the way they're conducting business outside the norms (e.g. allowing no hearings for passage of the AHCA in the Senate)  is also not helping matters.

Finally, the litmus test to see if the Republicans are genuinely serious about changing things hinges on whether they now have the intestinal fortitude to unshackle from the NRA and enact serious gun legislation. Personally, I doubt they will, which means all their hand wringing and calls for change are basically hollow.

In the meantime, Trump talks a good con man's patter  with his call for "unity" but as long as he continues his tweets which ridicule Comey, the FBI and law enforcement, as well as the media - he's merely belching empty noxious brain farts.

NBC Is Off Its Rocker To Air Alex Jones' Interview After Capitol Shooting


Image result for alex jones
Conpiracy clown Alex Jones, who feeds the Right's febrile conspiracies - including Sandy Hook being a false flag- to appear Sunday night on Megyn Kelly's show.

Incredibly, NBC News is moving ahead with plans to air Megyn Kelly’s interview with conspiracy theorist Alex Jones this weekend despite a backlash that has cost the show advertisers and led to Kelly being dropped as host for an event by an organization founded by parents of children killed at Sandy Hook elementary school.  And this is also after the shooting of House GOP Whip Steven Scalise and three others this morning during a GOP House batting practice in Alexandra, VA at Eugene Simpson Stadium Park.

It doesn't take a genius to figure out that the shooting this morning was specifically directed at the Republican House members getting ready for a congressional baseball game. Reports out of ABC News this morning note the perp didn't come in and just mow  people down indiscriminately with his AR-15, he asked where the REPUBLICAN players were, which they were. In other words, this was a political hit job in a highly polarized national atmosphere we've not seen since the Civil War.

And into this atmosphere you are really going to throw gasoline on the fire by airing a Megyn Kelly interview with conspiracy screwball Alex Jones? Seriously? Yes, yes, I know all about the "free speech" thing and at any other time I'd say let Alex have his say. But not now in an overheated environment where from reports in a recent issue of  TIME - both Left and Right are amping up their aggression with the Alt-Right now squaring off against black clad Antifa (anti fascist) brigades, including here in Colorado Springs. E.g.
Antifa members organized at the UCCS Milo Yiannopoulos speech in January. - NAT STEIN
Anti -fascists square off against cops before the Milo Yiannapoulis appearance at UCCS in January.

Meanwhile, NBC  has been taken aback by the response to booking Jones, the Infowars host who has questioned the factual reality of the killing of 26 people in 2012 at Sandy Hook Elementary in Newton, CT. He has insisted it's a hoax, a "false flag",  staged by the Obama administration as an excuse to seize guns. The students shot and killed, in Jones insane view, were merely actors - who are still alive and well somewhere. He refuses to say where, though he evidently knows where the Roswell aliens are ensconced.

NBC News Chairman Andy Lack, who had earlier mulled firing Lawrence O'Donnell - one of the most popular liberal voices on MSNBC -  said the story would be edited with the sensitivity of its critics in mind. But if NBC is going to really give Jones his 0.02 it is hard to imagine how such editing might be done. Virtually every word out of Alex Jones' mouth is inflammatory and polarizing. For example, on Oct. 25th Jones spewed on about a crypto Jewish conspiracy afoot in the country:

I mean it’s not that Jews are bad; it’s just they are the head of the Jewish Mafia in the United States. They run Uber. They run the health care. They’re going to scam you. They’re going to hurt you.” 

NO  hard data, or cited documents for that claim, or even a tempered speculation. Jones simply emitted a noisome brain fart from a ruptured psychotic embolism in his amygdala. Given he does this every ten microseconds, how will NBC "edit" his stream of bullshit brain modality?  Well, I guess NBC could shut off the audio during Jones' responses and just let the lips move soundlessly.

“It’s important to get it right,” Lack said.  To which I'd respond, "It's impossible to get it right when you put a crackpot on the air".  And especially in an overheated political atmosphere now made worse by what had obviously been a partisan-motivated mass shooting.

Kelly had the nerve to argue last Tuesday that reporters have interviewed controversial characters such as Syrian president Bashar al-Assad and child molesters in the past without getting this kind of a reaction. But she misses the key point most everyone knew and accepted those were bad guys. In Jones' case, his febrile follies have been the fodder and launch point for much of the fake news, including 'Pizzagate', spouted with cooperation with the Russkies' own spurious crap.  Indeed, Jones' crappola has been one of the main media diets of Donald Trump, likely fueling his own halfwit conspiracy musings  - including Ted Cruz' dad being one of the Kennedy assassins.

Note here that popularity of a stone screwball does not qualify as a justification to give his screwball ideas major network hearing. (I have no problems if it is done via an online interview, but not a prime time airing on a major network).  Thus Kelly's next blather:

What I think we’re doing is journalism. The bottom line is that while it’s not always popular, it’s important. I would submit to you that neither I nor NBC News has elevated Alex Jones in any way. He’s been elevated by 5 or 6 million viewers or listeners, and by the president of the United States. As you know, journalists don’t get the choice over who has power or influence in our country.”

Which is a too cute, too pat and too egregious explanation by far. Especially given that Jones' popularity has not been on account of the attention of rational, sober citizens, but of unread, semi-educated screwballs like Jones. Oh, and liars and fake news buffoons like Donald Trump. Hence, Kelly - and Lack - are cherry picking what they regard as "journalism", in this case defining it down to the level of the fake news dumpster. In other words, if you give a fake news purveyor major air time then you become a fake news purveyor too. If you want to delude yourselves this is "journalism", fine, but don't take the rest of us for stock idiots.

Sandy Hook Promise, an anti-gun violence group, said it had asked Kelly to step down as host of its Wednesday-night gala in Washington. The group said it cannot support Kelly or NBC’s decision to give a platform to Jones and hopes NBC reconsiders its plan to broadcast the interview, said Nicole Hockley, co-founder and managing director. Hockley, whose 6-year-old son, Dylan, was killed at Sandy Hook, founded the organization with Mark Barden, who lost his 7-year-old son, Daniel.

To some critics, NBC’s timing makes the decision worse – airing on Father’s Day an interview that has been publicly denounced by parents who lost young children at Sandy Hook.  But now with the politically motivated shooting this morning that decision is rendered even worse by orders of magnitude.  NBC said it was scheduled "for competitive reasons", because Jones had been booked to appear on ABC’s daytime show The View next week. (A representative of The View said Jones had canceled his appearance there and he would not be rescheduled.)

Lack noted that he had suggested approaching Jones for an interview to David Corvo, the NBC News executive who supervises the network’s newsmagazines. He said there’s nothing new about putting people on the air even if they’re unpopular or have views that are deplorable to many, adding:

I’ve got tremendous understanding of why they’re so upset, as they have every right to be,”

Ahhh, but he has more appreciation and "understanding" - by far- of the ratings hike he hopes to snare by putting an obnoxious, pseudo-conspiracy gasbag like Jones on the air. The best thing sober people can do is tune it out, or watch 'Fear the Walking Dead'.

Meanwhile, Trump lackey Jeff Sessions performed yesterday as most of us expected, i.e. like the Trump patsies Mike Rogers and Dan Coates did last week. See, e.g.

Excerpt:

"In the flap over Kelly’s upcoming interview with Jones, one fact critics keep missing, or willfully ignoring, is that Kelly and Jones are two sides of the same coin. Sure, Jones arguably says more outlandish things from a position that used to be the far lunatic fringe. But Kelly spent more than a decade doing her own version of the right-wing’s dirty work from within the establishment at Fox News. The difference between Kelly and Jones, at the end of the day, amounts to nothing more than aesthetics. Together, their steady output of garbage has helped expand and thicken our current toxic atmosphere, which is now engulfing and threatening to choke us."

Science Education Hamstrung By Dubious Laws & Flawed Intuitive Ideas

















Let's face it, learning even basic concepts for physics and astronomy does not come naturally for most people. Even teachers!  I discovered this while giving the first teacher workshops in the teaching of astronomy for the Caribbean, back in 1978.   Among the beliefs I encountered among these teachers who were to devote themselves to the first ever serious secondary school astronomy syllabus :

- The stars were merely pinprick size holes in a vast dome called the night sky

-  The Sun was not a star but totally different, real stars were tiny bright points

-   The Sun went around the Earth not the other way

-   The Moon had to be the same size as the Sun to cause solar eclipses

Each of these, in fact, can be traced to the person's intuition or what the cognitive scientist Andrew Shtulman calls "intuitive theories". In other words, misbegotten notions of how the world or universe works based on internalizing goofy ideas that seem right but aren't.

Of course, it's no different with physics. Millions still accept or believe that heavier objects must fall to the Earth faster than lighter ones. This despite the fact that it's been experimentally demonstrated since the time of Galileo that all object fall at the exact same rate, once air resistance is corrected for.

Others believe firmly in an "impetus" kind of motion originating with some kind of imaginary force that fades over time, despite the fact that Newtonian physics allows no such "force.

Then there are those who are certain that linear transfer of momentum is a myth, so that when they see Jackie Kennedy in the Zapruder film moving back over the limo trunk to try to retrieve a dislodged occipital bone from JFK's head, e.g.
No photo description available.
They still are unable to process the shot had to have come from the front. A bullet fired from the rear hitting the back of Kennedy's head could not possibly drive it back toward the rear shooter because the linear momentum imparted is not in that direction.  A rear shot instead would drive the head forward and its content out front. Basic stuff, but it still boggles minds.

To demonstrate the principle of linear momentum transfer in a lab setting is fairly straightforward, making use of an air track, of the type used to measure accelerations, e.g.

In the case of momentum transfer we ensure the track is level so there is no extraneous acceleration from gravity and place a stationary trolley on one side while sending the other in motion from the opposite side. The student who performs the lab will see the moving trolley strike the stationary one (we assume both of the same mass) and then both move off in the same direction, i.e. the direction of the moving trolley. (N.B. there is no 'rubber' bumper on the stationary trolley).

Millions more are equally befuddled by the idea that forces always occur in pairs, so a book (A) resting on the table (B) - exerting the force of its weight F(AB), must have the table also exerting a force on it (F(BA).
No photo description available.
This is an application of Newton’s 3rd law which states that “for every action (force) there is an equal but opposite reaction (counter force).

All of which informs us that it isn't sufficient to rely on our intuition of a physical system to understand what is going on.  That intuitive picture, alas, is generally flawed.  The success of science education, then, lies in eliminating as many flawed intuitive ideas as possible and replacing them with correct scientific principles.

In physics, at least, this is relatively straightforward to do by way of experiments, i.e. dropping objects from a set up such as shown below - connected to an electronic timer which imparts dots on tape that can then be compared with the accelerations computed..


One can then check to see that a 5 g mass and 20 g mass fall at the same rate, hence have the same accelerations subject to  the Earth's gravity.

With the proper equipment other experiments can also be devised, say to test the principle of linear momentum transfer, or that heat is transferred from hotter to cooler bodies. 

In terms of the astronomy misconceptions already cited, while it is not possible to perform actual experiments, it is feasible to use models to high light false thinking. For example, using two balls of very different size - say one a 1 cm marble, the other a softball of 9.65 cm diameter, to represent the Sun and Moon. Then by placing the former much nearer to the observer's eyes and the latter much further away, it can be shown how the marble (representing the Moon) can exactly block out the larger (Sun).  All that's needed is getting the right distance to the observer for each to produce the "block out" effect (similar to what happens in a total eclipse. Most importantly the Moon needn't ne the same size as the Sun - only the same angular size (e.g.1/2 degree or 30 arcmin) when the eclipse occurs.

Similar techniques using light sources can be used to show - in a model situation - that the Sun is a star, and only appears much different (and brighter) because it is so much closer to Earth than other stars.  Place a bright torch or flashlight within 1 meter of an observer - say to show the "Sun" from Earth, then change the distance to 100 m (needing a large field - preferably at night) to see just a tiny point of light. The light source is the same, it's just observed from radically differing distances. The same applies to the Sun and other stars, they only appear to be different entities because the Sun is observed much closer than the other stars.

While the challenge of dismissing false ideas is significant, the science educator also faces spurious "first amendment" arguments by state legislators, trying to dignify pseudo science in evolution and climate science. For example,  in South Dakota, supporters of SB 55 claimed the bill was necessary to "protect the academic freedom and free speech rights of teachers". A challenge by the National Committee Against Censorship (NCAC) pointed out that while teachers have the right to their own opinions they do not have any First Amendment right "to deviate from and possibly contradict professionally developed science standards adopted by state educators".   The argument led to the defeat of the bill.

Similarly, in Oklahoma, an anti-evolution legislator proposed a bill that would allow teachers to present alternatives to evolution such as creationism. Of course, creationism is not science in any manner, shape or form it is religious doctrine.  It is simply gussied up with scientific seeming terms. Creationists don't even provide their own tests for falsifying their own alleged theories! For example, the evolutionist provides a falsification test for his theory of common descent (i.e. that both Man and apes are descended from the same common ancestor) by using the cytochrome-c sequence, say as disclosed in chimps and humans, and asserting that beyond a certain (probability)  threshold the test fails.

This OK bill is now also under challenge by the NCAC.  Because of these contentious legal issues and states unwilling to accept standard science, Andrew Shtulman, in his book SceinceBlind, suggest evolutionary concepts need to be taught before high school using graspable charts.  E.g.













Diagram showing the putative evolution of late Devonian fish.


















Let's agree it is by no means easy to dispel flawed notions of science based on intuition or religious belief, not to mention those interjected via misplaced state laws. The educator needs to realize it's a ceaseless struggle.  Research shows that even general lessons in critical thinking do not measurably improve performance on science tests. (Mostly because too many such tests are still based on content).  But never mind, they are still useful for engendering a citizenry capable of applying skepticism  to pseudo-scientific claims - especially the type that bombard us each and every day.
