    The article summary states the power at 100Hz, but then says the pulse is 50ns long - during which interval a 100Hz base frequency is irrelevant....

    Standard directional antennas won't have much effect on a 50ns pulse, but I'm sure the pulse can be directed.

    It's a better measure than clock-speed these days, size has fairly good correspondance to power efficiency and power efficiency is the main thing holding back higher clock speeds. It's also nice to be able to fit more cores on a single chip, and size helps with that.

    And, yeah, the Lit-Mag was pretty much a joke - no more so than any number of other classes in HS, but I think curriculum they were trying to teach had more to do with respecting authority than anything related to literature, publishing, or other academic things.

    Back in the day before web-postings, I participated in a class that worked on the annual "Literary magazine" - a photocopied bunch of stories and artwork done by students. I had a friend who was a good writer but happened to attend another school. I submitted one of his stories on his behalf via the normal submission process - there was a tradition about work only coming from my school, and an obscure rule (which I, of course, knew about, but I was 15 at the time....), but the story got in (along with 350 other pages of marginal material produced by high school students), and I pushed in the class to get it an award - it tied for 3rd place. I disclosed the story's origin to some of the other kids in the class one day before printing - they felt the need to tell the teacher who viewed the whole thing as his personal achievement in life (besides marrying an ex-student after she turned 18 years old... but I digress), and he felt the need to expunge the offending story from HIS magazine, correct the awards page, etc. etc. Took him about 4 hours.

    Long story short, I did something really really minor that pissed off a teacher in a big way. They suspended me for 3 days for "breaking literary magazine policy", and there was really nothing to do about it but take the lumps. If the teacher hadn't been in tight with the disciplinarian, he might have been laughed out of the office.

    Timing plays a big part in how these things work out - if they had tried to suspend me for 10 days, it would have been worth fighting and they would probably have lost. You might try to fight your case, but in all likelyhood you're better off taking the lumps and getting on with life.

    A PIC microcontroller and compatible GPS can handle your computing load for "real-time" sailing control.

    The only computing/electronic thing I'd wish for beyond GPS would be real-time weather data, more for storm avoidance than any wind-speed advantage - but I don't think you'll be getting that reliably in the middle of the Atlantic???

    Really, you're more likely to have a stuck actuator than a computer system crash. I'd look to proven designs for radio-controlled sailboats, work up an algorithm to sail with the available wind (and furl before it hurls), and implement it on something that doesn't have a million lines of code in the OS.

  6. Re:Entanglement and causality? on "Spooky" Science Points Towards Quantum Computing · · Score: 1
    The leap of faith that I fail to make is that the complimentarty states weren't set at the time of entanglement.

    Repeating myself: perhaps the entangled particles have merely been set to complimentary states by the process of entanglement - the observer may not know this until he takes a measurement, but that lack of observation doesn't make it any less true that the particles are in complimentary states during the interim.

    It seems far easier to believe that a particle may retain a given (albeit unknown until measured) state for a period of time, rather than "spookily" acquiring a complimentary state at the time its partner is measured. That entanglement doesn't set a known state, only a random but complimentary state for both particles, isn't so mysterious.

    From the practical point of view, I don't see any measurable difference between the two explanations. The "spooky action at a distance" explanation seems to give more influence to the observer than perhaps the observer merits.

    Only then purely because you looked at the red box from a different angle the blue ball instantaneously shifts position even if the two boxes are lightyears apart.

    I guess I just lose the thread at the point when you can't examine the blue ball to know if it has shifted position or not, without also destroying the entanglement.

    Now, if you could make a two groups of entangled pairs A1-B1 and A2-B2, send the Bs to Mars, then measure either A1 or A2 in your spooky effecting method, if the Bs gave any clue as to which A was measured - that would be forming a useful communication channel - which is supposed to be "against the rules." And, if there's no way to look at B1 and B2 and tell whether A1 or A2 was measured (without that information passing through another channel), how do you really know anything?

    Actually, typing this all through - it starts to make a tiny modicum of sense, which probably means it's bedtime.

    Ah, but it (the secret key) was sent - just as "entangled" particles. The only value here is that the state can only be read once, then it self-destructs, and I'm not sure that's entirely true (what if someone is looking over your shoulder as you read the state?)

    The "instant effect" has always eluded me. I have two balls, and inside each is a disc magnet with red on the N side and blue on the S side. I bring the balls together in a closed box and they become "entangled", with the magnets lining up one red on top, one blue. I separate these balls without "measuring" them, later measure them and "voila!" one is red up and one is blue up. So, why would I be impressed with sub-atomic particles doing the same thing? If you're not able to transfer information across the "entangled link," how can you prove that anything is happening? To me, this notion that the particles "have no specific state until they are measured" is hogwash - I say they do have a state, but the observer just doesn't know it yet. That the state is disrupted by being observed is easy enough to grasp - but all I get out of entanglement is that the particle pairs have properties set in complimentary states that have not been measured and will not be disturbed or changed until they are measured.

    I have had a tough time with how much to treat my sons who have been diagnosed Autistic... I don't want to go down the radical rabbithole of hyperbaric chambers and injectable cocktails of amino acids (which have been around long before this group published.) Even if my boys were "cured" - at what cost? What happens when they go off the meds, or we can't afford them anymore? And what do they lose by being "cured"? Like all fathers, I'd kind of like my sons to have what I have had, only better - if they become "normal, average kids," I look at "normal, average" people my age and I think that I'm doing quite a bit better than them.

    I'm somewhere on the spectrum (we all are, that's what a spectrum implies...), but I'm not as far to the autistic end as my sons, I could carry on some kind of conversation (and read aloud) when I was 4, they're still struggling with simple communication at 3 and 5. At this point, I'm glad nobody cured me - looking back at my life at all the things I would have chosen to do if I could have when I was younger, especially dating / relationships, if that had worked out for me back then, I think I would have been worse off now.

    So, the eldest just went back on a Gluten free diet - it's a semi-radical thing to do, but he was slowly regressing in important areas over the 6 months we had him on "normal foods," and removing Gluten for 18 months seemed to help last time. It's connected to the inflammatory processes they mention in the article - removing it can reduce inflammation, or so they say. It's all black art at this point, even long-established things like high doses of B12 have poorly characterized effects. I certainly don't want the state telling me I have to deliver a certain bio-chemical treatment to my children (as they do with vaccines), but I do want to be allowed to choose to pursue reasonable treatments that may help. I just don't want to build my children up on a house of cards that may collapse out from under them some day, leaving them worse off than if we had just skipped treatment altogether.
