House Oversight Committee UAP Hearing Today

We watched the House Oversight Committee UAP Hearing today and it was one of the most interesting presentations we’ve seen in a long while.

I make fun of the topic a lot but I thought all the witnesses were credible. In my opinion, the most credible witness today was retired Commander David Fravor of the U.S. Navy. His sense of humor and down-to-earth (no joke intended) demeanor lent credibility to the issue of Unidentified Anomalous Phenomena.

I especially liked Fravor’s advice for anybody reporting UAPs: “Don’t make the fish bigger than it is.

David Grusch, a former U.S. intelligence officer, often deferred answering certain questions because the answer would have meant revealing classified information. Ryan Graves, a former fighter pilot for the Navy, emphasized the need for a safe way to let military and civilian witnesses describe their encounters with UAPs.

There will likely be another meeting, one which would allow David Grusch to be more open to answering questions involving classified information.

Can Robots Lie Like a Rug?

I’ve been reading Isaac Asimov’s book I, Robot, a collection of short stories about the relationship between humans and robots. One very thought-provoking story is “Liar!”

One prominent character is Dr. Susan Calvin. If you’ve ever seen the movie I, Robot you know she’s cast as a psychiatrist whose job is to help humans be more comfortable with robots. In the book she’s called a robo-psychologist. She’s a thorough science nerd and yet goes all mushy at times.

The news lately has been full of scary stories about Artificial Intelligence (AI), and some say they’re dangerous liars. Well, I think robots are incapable of lying but Bard the Google AI did sometimes seem to lie like a rug.

In the story “Liar!” a robot somehow gets telepathic ability. At first, the scientists and mathematicians (including the boss, Dr. Alfred Lanning) doubt the ability of robots to read minds.

But a paradoxical situation occurs with the robot who happens to know what everyone is thinking. This has important consequences for complying with the First Law of Robotics, which is to never harm a human or, through inaction, allow a human to come to harm.

The question of what kinds of harmful things should robots protect humans from arises. Is it just physical dangers—or could it be psychological harms as well? And how would a robot protect humans from mental harm? If a robot could read our thoughts, and figure out that our thoughts are almost always harmful to ourselves, what would be the protective intervention?

Maybe lying to comfort us? We lie to ourselves all the time and it’s difficult to argue that it’s helpful. It’s common to get snarled in the many lies we invent in order to feel better or to help others feel better. No wonder we get confused. Why should robots know any better and why wouldn’t lies be their solution?

I can’t help but remember Jack Nicholson’s line in the movie “A Few Good Men.”

“You can’t handle the truth!”

Dr. Calvin’s solution to the lying robot’s effort to help her (yes, she’s hopelessly neurotic despite being a psychologist) is a little worrisome. Over and over, she emphasizes the paradox of lying to protect humans from psychological pain when the lies actually compound the pain. The robot then has the AI equivalent of a nervous breakdown.

For now, we’d have to be willing to jump into an MRI machine to allow AI to read our thoughts. And even then, all you’d have to do is repeat word lists to defeat the AI. So, they’re unlikely to lie to us to protect us from psychological pain.

Besides, we don’t need AI to lie to us. We’re good at lying already.

Every Minute Counts in Physical Activity for Health Even If Your Step Counter Does Not Count It!

If you want a quick read for how every minute counts in physical activity for your health, see the JAMA article “Physical Activity for Health—Every Minute Counts” (Katzmarzyk PT, Jakicic JM. Physical Activity for Health—Every Minute Counts. JAMA. 2023;330(3):213–214. doi:10.1001/jama.2023.11014).

Just for fun, I tried to see if about 5 minutes of juggling would result in a change in the step counter on my cell phone. Unfortunately, it didn’t but I sure could feel the effort!

As the authors state, public health recommendations for physical activity set a bar of 150-300 minutes a week of moderate intensity aerobic activity to get substantial health benefit.

But you benefit from just about any increment below that level. Your step counter probably won’t register it, but you can feel it.

I made a short demo video to show what good exercise juggling is. I didn’t cut any mistakes (and obviously increased the speed on it because 5 minutes is a bit long). Anybody can tell I’m pretty puffed out at the end.

Try juggling for physical activity!

I’m Reading Isaac Asimov’s Book “I, Robot”

I just got a copy of Isaac Asimov’s book “I, Robot” the other day. I’ve been thinking about reading it ever since seeing the movie “I, Robot.” As the movie opens, you see the disclaimer saying that the movie was “…inspired by but not based…” on Asimov’s book of the same name.

In fact, the book is a collection of short stories about robots and in the first one, entitled “Robbie” I saw the names of several characters who were transplanted from the book into the movie, Susan Calvin (the psychiatrist), Alfred Lanning, and Lawrence Robertson.

Robbie is the name of the robot who has a special, protective relationship with the 8-year-old daughter of parents who don’t agree about how Robbie could have a positive influence on the girl.

The first of the 3 Laws of Robotics is mentioned in “Robbie.” It is central to the close bond between the little girl and the Robbie All 3 are below:

First Law

A robot may not injure a human being or, through inaction, allow a human being to come to harm.

Second Law

A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.

Third Law

A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

I just started reading the book. I read a few of the negative reviews of the book on Amazon because when most reviews are effusively positive, it’s difficult to get a balanced view of what the flaws might be. One person called it an “old chestnut” and gave it only 2 stars. Another reader was put off by the old-fashioned portrayal of the relationship between men and women.

Well, after all, the book was published in 1950.  A description of their relationship goes like this between the husband and wife:

And yet he loved his wife—and what’s worse his wife knew it. George Watson, after all was only a man—poor thing—and his wife made full use of every device which a clumsier and more scrupulous sex has learned, with reason and futility, to fear.

I’m not at liberty to comment about this.

Moving right along, the story addresses the fear people had of robots—which many of us still have now, in the age of Artificial Intelligence (AI). We tend to forget AI is not independent, like Virtual Interactive Kinetic Intelligence (VIKI) in the movie I, Robot. Why does it have a female name?

Talk about the stereotypical men and women of the 1950s.

Watch Out for Spaghettification on Skinwalker Ranch!

I’m not up to speed on the math of black hole portal wormhole vortices and whatnot, but I think the actors on The Secret of Skinwalker Ranch need to be careful what kind of incendiary devices they’re tossing into the Triangle Area.

I barely got through the general physics introductory course at Iowa State University. I remember the momentum lab experiments—barely. My lab partner showed up late because he was really hung over. I think he asked me if I ever partied and I said I had pretty much outgrown that kind of thing. He looked at me like he was shocked and exclaimed, “You mean this crap ends?”

On the other hand, despite his hangover he grasped the momentum math better than I did.

I’m still trying to figure out why one of the actors said “A black hole?” when somebody posed the question “What does that thing look like?” referring to what looked like a black hole at ground level following a LiDAR imaging test in the Triangle Area. I didn’t know you could find black holes with LiDAR.

There was also the suggestion of funnels in the air above the black hole, leading to the team wondering if it was a portal leading to a wormhole. Everybody got excited about it, and wondered if it might explain all the weird stuff happening on the ranch. Could there be monsters, extraterrestrials, orbs, and Braunschweiger with Miracle Whip sandwiches zipping in and out of these things?

It got me looking around on the internet to find out whether black holes and wormholes could be the same thing. It turns out some scientists think there could be black hole portals on one end and white hole portals on the other end of wormholes, which I think means you get spaghettified on one end and reassembled on the other.

However, this could mean you have to be wary of spaghettification if you try to travel to another dimension through a wormhole. You don’t have to take my word for it (and you shouldn’t!). Just ask physics professors Leo and Shanshan Rodriguez at Grinnell College in Iowa. Black holes swallow up everything that comes within spitting distance from them, stretch them way out so they resemble noodles and eventually destroy you.

The only thing you can do then is call Chuck Norris, who routinely eats black holes with Braunschweiger and Miracle Whip for lunch (they taste like chicken) and farts them into another galaxy far, far away. Chuck’s side hustle is to work part time at the Large Hadron Collider (LHC) where he is a part time janitor, sweeping up the little black holes it sometimes generates. That black hole the LHC created in 2012 which swallowed reality didn’t stand a chance against Chuck, who gargled it and spat reality back out.

This goes back to Einstein’s theory of general relativity of course, which proves by advanced, hyper galactic step over toe hold jujitsu level mathematical formulas that the stitches in the fabric of spacetime get all warped leading to a crazy strong gravitational pull involving stirrup pants that stretch you enough to motivate some men to spend any amount of money to increase their penis size including subjecting themselves to black holes such that they would need a carryon bag to haul it through Chicago O’Hare and believe spaghettification is just the trick although airport security has yet to devise how they can get it through the screening machine in order to avoid pat down searches which can not only tickle but also delay passenger boarding and lead to mass hallucinations of a big UFO similar to the O’Hare event in 2006, which was actually caused by a weather event according to men in black suits posing as FAA agents at the airport.

Does anybody else have a sudden craving for pasta?

Thoughts on Battery Powered Toothbrushes

Sena bought a couple of Equate Polaris Vibraclean non-replaceable battery-powered toothbrushes with charcoal bristles (see below for remarks on charcoal) for us. When the battery dies, you just throw the brushes away. We had a rechargeable electric toothbrush a long time ago, but getting replacement parts for it was too expensive. We went back to manual toothbrushes.

You just press the on button and you’re buzzing. You press the off button when you’re done. It’s a little tough to refrain from trying to manually brush, but the internet entries say you should do that anyway.

Sena says the battery-powered toothbrush feels weird rumbling in her mouth. I think it does a good job of massaging the gums and tongue as well as cleaning teeth.

I found a couple of studies published about twenty years ago that compared electric and battery-powered toothbrushes. They didn’t find any difference. The few studies that have been done generally find the battery-powered toothbrushes are superior to manual brushing.

The American Dental Association (ADA) says either manual or electric brushing works fine—compared to not brushing at all, I guess. The ADA web site has list of the organization’s preferred electric products. The Equate brand of battery powered brushes apparently didn’t make the cut.

Some brushes (including ours) have charcoal bristles, which supposedly whiten teeth. After looking on the internet, I’m not so sure that’ll work. In fact, the ADA has a low opinion of charcoal-containing dental care products. There’s no evidence that they’re effective or even safe, according to the September 2017 issue of The Journal of the American Dental Association. They might even wear away the enamel.

Hmmm. Maybe charcoal is not the best thing?

The brushes were a bargain—oh well, back to manual brushing. On the other hand, there’s plenty of evidence that regular brushing with toothpaste along with flossing is good practice.

Wormhole Vortex Portal at Skinwalker Ranch!

I watched The Secret of Skinwalker Ranch the other night and the investigators got really excited over seeing what they called a wormhole portal in the Triangle area of the ranch. Somehow, it was detected by LiDAR, which stands for light detection and ranging. It measures distance using light instead of sound like radar does.

I didn’t know you could use LiDAR to detect wormholes.

Anyway, the whole team including Travis got so worked up about it the show got interrupted so that all the actors (I mean investigators) could calm down by mindfulness meditation. It was better than finding a mutilated cow.

Prior to finding the wormhole, they had guys shooting rockets, flamethrowers, and electricity bolts into the sky at about the 30-foot level where weird things usually happen, like orbs.

You never see much beside orbs. I’m not sure how you think of an orb of light as a UFO or spaceship that could be drivable by an extraterrestrial. I can’t imagine a humanoid fitting into an orb and operating it even with something like a car with a push button transmission. Remember those? When I was a kid, we had a friend who got one. She was really proud of it. I think it was a Chrysler from the 1950s.

I’m not sure where they’ll go with the wormhole thing now. Would they ever try to enter the wormhole? I thought wormholes destroyed everything that got too close to them.

They’ve been stuck for so long to come up with something different to give viewers the idea that there’s something really paranormal out there that they’ve had to add an extra show, Beyond Skinwalker Ranch. I haven’t watched it; it comes on a little late at night for me.

Next week they’re going to have the Utah State Attorney General as a guest star again out to the ranch. It looks like the military is out there buzzing the area with various black helicopters and generally getting everybody indignant and all worked up. Why should the military care what they’re doing? After all, it’s not illegal to shoot hobby rockets, flame throwers, and electricity bolts at the air, even if it might have a wormhole not covered by insurance in it.

What’s Up with Shared Clinical Decision Making for the RSV Vaccine?

There are probably some questions about the new Respiratory Syncitial Virus (RSV) vaccine. Because I’ve seen TV commercials about the new website RSVandMe, I checked on a few things the other day.

The RSVandMe website and the companion website are both produced by the RSV vaccine maker GlaxoSmithKline (GSK). As such, I consider them marketing commercials.

I checked the Centers for Disease Control (CDC) website and saw that the CDC Advisory Committee on Immunization Practices (ACIP) recommended approval of the RSV vaccine at their June Meeting (covered earlier on this blog):

Adults 60 years of age and older may receive a single dose of Respiratory Syncytial Virus (RSV) vaccine, using shared clinical decision-making.

The term “shared clinical decision-making” is clarified on the CDC webpage at this link.

The upshot of shared clinical decision-making is that it’s up to the provider (the list of providers include pharmacists). So far the list of recommended vaccines does not yet include RSV, so it probably needs updating. It looks like the ACIP MMWR recommendation page also needs updating.

What’s Up with Seasonal Vaccines This Fall?

I just read an interesting article in JAMA on this fall’s Covid-19 vaccine. Most of it is from the FDA meeting in June (Rubin R. This Fall’s COVID-19 Vaccines Will Target Omicron XBB Subvariants, but Who Needs Them Remains to Be Seen. JAMA. Published online July 05, 2023. doi:10.1001/jama.2023.10053).

One expert was quoted, indicating that there will be “…an elaborate discussion” at the CDC ACIP meeting about who should get the new monovalent XBB.1.5 vaccine. I don’t see that the meeting is scheduled yet.

There are some other interesting quotes to pass along:

“Back in March and the first half of April, XBB.1.5 represented more than 80% of circulating SARS-CoV-2 in the US, according to CDC estimates. Its dominance began to slip in late April, and as of late June, XBB.1.5 represented little more than a quarter of circulating SARS-CoV-2 variants. By then, though, XBB.1.5 and 9 other XBB subvariants together accounted for a total of 96% of circulating SARS-CoV-2 in the US. Fortunately, members of the XBB family of subvariants are antigenically similar to each other, so a vaccine against XBB.1.5 should protect against the rest of them as well, the WHO committee noted.”

“By the third quarter of 2022, an estimated 96.4% of approximately 143 000 blood donors in a nationwide, longitudinal cohort had SARS-CoV-2 antibodies from previous infection or vaccination or both, according to an analysis published in June in Morbidity and Mortality Weekly Report.

Or, as Sawyer told JAMA, “[t]he whole US has had this virus in one form or another.”

Because of the high prevalence of SARS-CoV-2 antibodies in the population, Paul Offit, MD, in an interview predicted “a focused recommendation by the CDC” regarding who should receive the XBB.1.5 vaccine.”

“Offit said he expects that the CDC will recommend the new monovalent XBB.1.5 vaccine for groups at the greatest risk for severe disease, reflected in continuing hospitalizations for COVID-19. Those groups likely would include people who are 75 years or older, people with severely compromised immune systems, and pregnant people, Offit said.”

“At least for people 60 years or older, the fall vaccine situation will be more complicated than it was a year earlier, Schaffner noted. That’s because at its regular monthly meeting in June, ACIP voted to recommend that this age group have the option of being vaccinated against respiratory syncytial virus (RSV) after consulting with their physician or pharmacist.”

That would mean that there would be 3 vaccines coming in the fall: RSV, Covid-19, and influenza. Sena and I have been doubtful about why a conversation with a physician would be necessary for the RSV vaccine. We don’t know whether that means you couldn’t get it without a physician’s order. There are also questions about coadministration of the RSV and Covid-19 vaccines.

Because the time is coming soon for seasonal vaccines, we’re hoping the questions will be answered soon.

Thoughts on Extraterrestrial TV Shows

A couple of nights ago, I watched a few TV shows on the Travel Channel about UFOs, extraterrestrial abductions, implants, and whatnot. I think there was some sort of marathon given that it was the Independence Day weekend.

Anyway, I was surprised to see Marc D’Antonio on a show called Alien Invasion: Hudson Valley. The story is about a community of people there who report many encounters with extraterrestrials. I’m used to watching The Proof Is Out There on the History Channel, hosted by congenial and humorously skeptical Tony Harris. On that show, D’Antonio is one of the “analysts” who appraise photos submitted as evidence for the paranormal. He’s always pretty skeptical and presents a scientific demeanor.

However, D’Antonio is also a MUFON investigator (which I found out later) and on the Hudson Valley show, he gave a detailed account of having been visited by an extraterrestrial, lost time, and woke up later in his bed, covered in his own blood, later seeing a doctor who removed some big foreign object from his nose, which he reported had probably been implanted there by the extraterrestrial. He told the anecdote matter-of-factly and I was struck by his non-scientific attitude.

I guess he and many others like him are actors in this flood of UFO TV shows which are very entertaining and give the appearance of being investigative in their purpose. D’Antonio appeared to be an actor, which led me to doubt the authenticity of his role on The Proof Is Out There.

They kicked around the idea that extraterrestrials were implanting objects in people to track the ones who are Rh negative blood type. They suggested that extraterrestrials need to use humans as some kind of blood bank. That reminds me of a line from Men in Black II:

Newton: Gentlemen, before I start the tape, one more thing—what’s up with anal probing? I mean, do aliens really travel billions of light years just to…

On the other hand, the Hudson Valley thing was a confusing mix of ghost hunters and alien hunters. They used a device that I think they called an electromagnetic field (EMF) meter, which you can purchase on Amazon along with many other ghost hunting gadgets. The women actors shrieked predictably as they reported feeling invisible hands stroke their hair.

I thought the show was supposed to be about extraterrestrials, not ghosts. They tried to cover the bases by tossing out terms like interdimensional beings, ghosts, and extraterrestrials. Most IMDb reviewers generally panned the show as being unbelievably bad, which is right.

A program previous to that was about some podiatric surgeon named Roger Leir who removed a lot of foreign objects out of somebody’s foot and then claimed they were implanted by aliens. Leir sent the objects to a lab, which identified them as being made of common elements. Somehow, he got the idea they were from outer space.

But they didn’t mention that in the show. They brought in some other expert who claimed they were parts of alien nanotechnology. The only thing I could find out about that was on, oddly enough, an Ohio State University web page article about Leir that seemed out of place on the OSU website. The article was seemingly supportive of his claim that the objects were alien implants.

I think the shows should be more clearly identified as being entertainment in nature, not investigative. If they want to get more viewers, they might try adopting the Mountain Monsters approach, which is to make a parody about the subject. At least the humor would valuable.
