  1. Quantum Computers and the Many World Hypothesis.

    There have been several reports, lately, about how various quantum computers have been shut down, apparently because of the unpalatable? scary? results they have been producing.

    Linked below is an explanation about how quantum computers work (I confess I didn’t get all the way through this long, rather heavy presentation), which says that their stupendous computing capability is only possible because they are drawing resources–doing some of their computations—from/in other parallel universes. *

    If this is true, this looks like it proves that Hugh Everette’s much derided “Many Worlds Hypothesis”—a staple of many science fiction stories– is actually correct i.e. that there are an infinite number of worlds/universes–each one of which exists parallel to ours, and in the same time and space (in SF sometimes termed “Timelines”)–each one branching off from some original world/universe, and created by some action.

    We turn left– that’s one world created, we turn right–that’s another, we get sick and die in one world, we are healthy and don’t die in another, a butterfly floats on the wind and creates one universe, a bird comes along and eats it, that creates another universe. ad infinitum.

    (If true, this could also provide an explanation for the behavior of UFOs and NHI’s i.e. they are dipping into our particular reality from nearby parallel worlds.)

  2. Space Force report predicts future conflict with China, including ‘unrestricted spectrum warfare.’
    A frightening article about China’s pursuit of new weapons of war. Could there be a connection to the disappearances and deaths of a USA general and scientists linked to advanced research, and even Nancy Guthrie?

    Tools and weapons used against U.S. space assets will include electronic spoofing, deceptive signaling, occasional outages, delays in space launches, on-orbit maneuvers from unclear signals, targeted coercion and “cyber-enabled intimidation of personnel and families,” the report said.
    […]
    The report also reveals China is building a vast, AI-based platform dubbed “Supermind” that is tracking and recruiting millions of scientists and researchers around the world.

    Have a nice day! 🙂

  3. That video was excellent. I’ve never contemplated a cruise, not my style, but it was solid advice.

  4. the disappearances and deaths of a USA general and scientists

    That sounded pretty thin to me, not that such things can’t be nefarious. Mary Cleave said that the astronauts were warned about such things — that would be in the 1980s — and that they actually happened. Mostly overseas, IIRC.

  5. Sdfer re Hillel Fuld article

    That is an optimistic article. I did a search and some articles on the Internet verify that Iran has agreed to hand over the enriched uranium. And that the blockade continues.

    The drop in oil price and the big increase in the stock market indicate that the markets are putting some credence to the Hormuz straits being open.

    Why not? We can use some good news on this beautiful spring day.

  6. Have taken numerous Cruises, and like them. Ocean Going and River, all mostly good. The only time I really lived on a Ship was a 4 Month Cruise in the Med, curtsy of US Navy.

    We are getting Snow. Already 2 ins plus, of Wet Snow. Hovering around freezing.

  7. Going on a cruise in a couple of weeks. We talk to several people that are regulars, do back-to-back cruises, and on rare occasions someone “living” onboard. I couldn’t make it through her entire video, because she takes a while to get to her points, but I made it through 6.

    1) After about 5 cruises, we quit trying to “do it all”. Ships, especially Carnival, which it looks like she is on by the blue chair, want to create a constant entertainment package. That does get old. And since mostly cruise lines don’t update their shows or activities, it gets very easy to skip them for your own routine. So, I agree with her description, but I don’t think it going to keep people that want the lifestyle to quit it.

    2) I guess the control thing can be a problem. There are some ports I wished we had been there for a different amount of time or different time of day, but as an irregular cruiser, you know these things well in advance. Maybe she’s right.

    3 and 4) To me these are the same points. I think if you are used to city living, none of this will be different. And if it is an issue, cruise on the smaller boats. Also, adjust your hours (see issue 1). There are times when 90% of the ship is being occupied elsewhere, and you can find private places to hang out. This is especially true on popular ports, that you’ve been to so often that you just hang out on board.

    5) Shallow bonds and no community is mostly true. We’ve met and bonded with people during a cruise, but short of a few phone calls afterwards, there is no real connection. On the other hand, if you are regulars, you can bond with the crew in some ways. Romantic relationships with the crew are prohibited, but like any service, you can get to know them quite well. And you’ll see them week after week.

    6) Expensive mistakes? Yeah, that’s a problem. Especially if you are getting cruises by gambling for them. We figured out recently that if you are willing to spend a little over the cost of your next cruise in the casino, the cruise line will often comp you a cruise for free. Go spend $5k in a casino, you’ll get a cruise and likely drink package and upgrades. But you can pay for a cruise (especially single) for $1.5k. I don’t know a lot of people that can burn through $5k a week.

    Good video pick. I wouldn’t say the lifestyle is for everyone. We just like going a few times a year, but we did a 2-week “journey” and couldn’t wait to get off. Mostly it was because our close family and friends couldn’t do it with us.

  8. Viking River Cruises look tempting. Otherwise no. Our domestic situation at this time does not permit vacationing now and our health may not permit it later. If the country reprises the Spanish Civil War, I imagine our time and income will go to securing staples.

  10. P.S. Looked at some more of the YouTube video I linked to above, about quantum computers and computing, and it just gets more and more information dense, more and more weird, as it delves deeper and deeper into the details of quantum mechanics, and the fundamental basis of Reality.

  11. There have been too many “bong rip” presentations of QM, if you ask me. Especially considering that the discipline is technically in its third century at this point (since 1900 was the last year of the 19th century). We’ve all had plenty of time to get used to it.

    Planck published his quantized blackbody spectrum work in 1900. Einstein’s Nobel was for his photoelectric work in 1905. Heisenberg’s uncertainty principle came in 1927. Feynman’s Nobel was awarded for work done in the 1940s. Babies born then have grown old and died, and their grandchildren are still bong-ripping about quantum mechanics. It was already old hat in the Sixties.

  12. I used to do a kind of calculation where you would rewrite the time evolution of a quantum mechanical system in terms of imaginary time, and then the calculation would evolve the system through imaginary time and give you the ground state solution to the equations even if you had no idea what it was in the beginning. (It was a lot faster if you had some idea to start with and in general we did.)

    It would be very easy to write about this in a bong-rip way. Imaginary time, far out. But all this really meant was, whatever a system is doing, there is some way to extract the desired solution out of it, and the “imaginary time” calculation was just a way to let the “noise” boil off so to speak and then allow the desired solution to emerge. It was just a math technique.

    It’s like the people who apply Fourier analysis to the stock market and then they give all these names to the “cycles” and treat them as mysterious agents of causation. I think “bong rip” popularizers of quantum mechanics are doing something very similar. I guess it works, since they still sell books, at least fifty years in, since I think these kinds of books got started in the 1970s, the earliest one I know being Capra’s “The Tao of Physics”.

  13. Unfortunately, never ran across the phrase before, and I have no clear idea of what a “bong rip” is.

    I take it from the phrase it might mean something spectacular which is supposed to “blow your mind,” a psychedelic trip through new science, a radically new way to look at the world and Reality, or something.

  14. P.S. Incidentally, never interested in really getting heavily intoxicated by/addicted to anything after–as a medic in the military–having to stuff a chronic alcoholic (his drink of choice I heard was Saki, gallons of it each day), yelling about all of the ants which were crawling all over him, into a straight jacket.

    (And, yes, even though the canvas in that straight jacket is very thick, it has heavy metal buckles, and thick leather straps, you can wriggle out of it or, with enough hysterical strength, you can rip it.)

    That’s why, when the doctors these days discharge you from, say, the emergency room or a hospital, and they hand you a week long or more supply of Oxy, that Oxy goes straight into the trash.

  15. @Snow on Pine:I have no clear idea of what a “bong rip” is.

    It’s the noise made when inhaling marijuana smoke through water, and accompanies many dorm room bull sessions. It sounds a bit like a soda straw does when the cup is nearly empty.

    something spectacular which is supposed to “blow your mind,” a psychedelic trip through new science, a radically new way to look at the world and Reality, or something.

    The illusion of it, rather.

  16. Go Trump. Hit them where It hurts.

    U.S. launches ‘Operation Economic Fury’ to obstruct Iran’s revenue streams amid blockade
    Senior officials signaled how the Trump administration is augmenting the war effort with economic pressure against Iran.

    Treasury’s Office of Foreign Assets Control revealed on Wednesday that it has been intensifying pressureon Iran’s allegedly criminally-run oil transportation infrastructure. 

    OFAC sanctioned more than two dozen individuals, companies, and vessels operating within the network of Iranian oil shipping magnate Mohammad Hossein Shamkhani. He’s the son of senior Iranian security official Ali Shamkhani, who was killed by U.S. strikes on the first day of the war. 
    “Treasury is moving aggressively with Economic Fury by targeting regime elites like the Shamkhani family that attempt to profit at the expense of the Iranian people,” Bessent said in a statement. “Under President Trump’s leadership, Treasury will continue to cut off Iran’s illicit smuggling and terror proxy networks. Financial institutions should be on notice that Treasury will leverage all tools and authorities, including secondary sanctions, against those that continue to support Tehran’s terrorist activities.”

  17. ArtDeco, not sure if you will see this, but I did a Viking River Cruise last Oct/Nov. Enjoyed it. Germany to Prague, did a post trip to Poland (land tour). Have done a lot of River Cruises, and did enjoy them all.

  18. The Heritage Foundation is streaming the 1:39:21 documentary (CallSignCourage.com) on X free for now of Lt Col Matt Lohmeier’s story in standing up against the toxic ideologies that were dividing the military, his firing after the 2020 election and return to service as Under Secretary of the Air Force.

    Here’s the 3 min trailer if you just want a taste:

    and the documentary on nitter for since X is age-restricting it:

  19. EXCELLENT Casey! I’ve been following Lt Col Matt Lohmeier’s travails, off and on, for years. I read his book.

    I’m quite ready and eager to watch this fresh documentary take!

    Bob Wilson shares the important clean up work initiated by theTreasury Department to cut off the Totalitarian Theocrats from all their foreign financial resources use to foster Hezbollah, Hamas, the Yemeni Rebels and much more.
    It is a story important enough to follow, too.

    CUT ‘EM ALL OFF at the knees, even if an Islamocratic Dictatorship survives Trump’s ongoing efforts. It’s of first level importance.

    Israel rules the peace in the ME, and has drawn her neighbors closer to mutual benefit. Trump and Benny together are making the ME safe for modernity to flower.

  20. @ sdferr > “Hillel Fuld with an extensive speculation on the current ceasefire-complex ”

    I believe Fuld has made a good argument.

    The accompanying graphic is very illustrative.
    https://pbs.twimg.com/media/HGGgXtwbEAAojfT?format=jpg&name=900×900

    I’m not sure where this part fits in, as it happened after he wrote his post.
    It refers to Trump’s ceasefire with Iran, not Israel and Lebanon, but everything there is intertwined.
    https://redstate.com/bobhoge/2026/04/18/trump-i-will-end-ceasefire-wednesday-unless-deal-done-but-xis-very-happy-as-hormuz-reopens-n2201418
    “Although the US.–Iran ceasefire is in effect for the moment (depending on who you ask), President Donald Trump signaled that things could change very quickly if the Islamic Republic doesn’t agree to terms — by Wednesday.
    Speaking on Air Force One, the president said the clock is ticking. In the meantime, the blockade will stay in force:”

    Wednesday is April 22; 10 days from the beginning of the Lebanese ceasefire is April 26. I’m glad I’m not the one keeping all these plates spinning!

    https://thehill.com/policy/international/5836115-israel-lebanon-ceasefire-agreement/
    “The 10-day halt in fighting began at 5 p.m. EDT on Thursday afternoon (4/16) — or midnight in Lebanon and Israel. The agreement stated that this is only the “initial” length for the ceasefire agreement, leaving the door open for further negotiation. “

  21. The healthcare issue precludes me from living on a cruise ship, unless I want to get a condo in Florida to make quarterly visits to the doctor. I have about 21 days I can travel. Anything longer becomes problematic (how to keep medicines below 46 degrees while flying or busing).

    Having said that, I cruise quite a bit. Have an Antarctic cruise coming up, another transatlantic next year, a Christmas village cruise next year, and in 2028, an Asia and a Norway cruise. Gotta travel while I still can.
