I approve of the not spilling of the beer.

It does looks like the Russians were the pioneers in this field though: https://videosift.com/video/How-Can-a-Glass-of-Beer-Demonstrate-the-Quality-of-a-Tank

Hey! No proselytizing in the classroom! 😉

Besides, the passage he read indicates that Christ’s birth would not be mid winter or the shepherds would likely not have been in the fields at night, it’s pretty cold and wet in Bethlehem (a 1/2 mile high city) in late December.
Any professor should know December 25th was Mithra’s birthday, a popular religious holiday, and emperor Constantine usurped it for Christianity as a way to consolidate religions to make it easier to use against the masses as a political tool.
You’re celebrating a dishonest political plot and an Iranian/Roman Pagan God’s birth, not the birth of Jesus.

WC Fields. No dogs or kids.

Maybe I can illustrate better.

The 'answer' they give is less clear than it could be for illustrating that purpose. That is to say, the very small electric current that is transferred 'wirelessly', would work exactly the same if your wire were never connected to each other period. Making it a loop as the example, then ignoring the transmission of force on the electrons along that connected wire is unduly complicating the example. If you want to illustrate that current in a wire generates a mag field, and that mag field in turn can induce a current in another wire is much better done by pointing out the result is the same if the wires are not connected.

It also avoids re-inforcing the very common misconception people have about electricity in wire not being subject the the speed of light...

Nah I dont see a bait and switch. I see people thinking electricity goes down wires while the underlying real world is fields propagating through space.

It really is a difference if you have the lightbulb 1 meter away or 1 light second away. We have a tendency to think abstractly of these situations, freely giving things ideal properties that they dont have and taking away the properties we dont like to use in our petty examples.

If you had enough voltage to overcome the drop in "ideal" 1 light second long cables they sure as hell would induce enough current in parallel cables 1 m away to light a bulb :-)

All that said people do under-appreciate how fast the speed of light is, just as they under appreciate how much a billion of anything, especially money, is.

The speed of light is getting to your destination instantly from your own point of view.

This is also a trick question, and in a way that I kinda dislike because it additionally confuses matters by the setup.

Specifically, any change to the electrical field in the wire triggered by something like flipping the switch IS always limited to propagating at the speed of light, and as such WILL take 1s to travel the ~300,000km through the wire.

There's a bait and switch here though, were if the wires are close enough, and the power on the wire is high enough, there is a strong enough magnetic field in the wire to reach across the 1m distance to the end of the wire by the light bulb. That magnetic field will induce a very small electric field on the wire as well. Calling that 'lighting' the bulb though is 100% a trick question though as no existing light bulbs are sensitive enough to light up from that little current unless the 'live' side of the wire is both in very close proximity and running very high voltage.

The part I dislike, is too many people believe that electricity running in a cable is 'faster' than light, and the trick here kinda re-inforces that rather than helping to clear that up for people.

Actually it’s both. The final forms aren’t stable in the real world, they shed particles that are ingested, vapors inhaled, who knows, they are likely absorbed through the skin from many products.

Assume they aren’t actually toxic, functioning as designed they coat digestive systems and, if the report is to be believed, individual cells in extreme cases, leading to things like digestive issues and vaccinations not working. In developing children, it sounds disastrous…and it’s everywhere and in everyone….often in high levels.

This is akin to a crop that’s mildly toxic, not one adjacent to a pre existing separate toxic weed. You can’t plant this crop without permanently contaminating the field, and adjacent fields, and the local water sources, and to lesser extent anyone who uses the crop. There’s no separate toxic weed here, just a toxic crop we keep planting in new places, making the contamination much much more widespread at constantly increasing levels with no way to clean it up and little knowledge of the long term effects of such contamination. Pretty big gamble to take with the entire planet just so your thin rain coat doesn’t leak, don’t you think? Especially with a non biodegradable easily spread but impossible to remove toxic chemical with relatively unknown cumulative effects and no method whatsoever for removing it from people or the environment….like this one.

Mate, if those two got any closer together, that LIGO would be detecting the birth of a new black hole somewhere in the Sol system.

I used to love Church: a dinner of Taco Bell burritos, a wooden pew, and the word of Christ. Clench, lean 15 degrees to the left, relax your sphincter and PUSH! The silence that is golden will last about 10 seconds before the retching and piling out the doors brings an end to today's sermon. That's when you snatch the collection plate and bolt out the back door.

I lost a major source of income when I became an atheist.

Did you know Taco Bell delivers? At least in Seattle they do. I have to wonder what life choices lead to the terminus of hauling two dollar food between source and the customer 25 miles away. Yeah, that $5 tip will more than pay for gas, upkeep, insurance and oil changes on that riced-out K car you've been driving since The Pet Shop Boys were still popular.

Also, "...blahblah whining and such..." -- look, if I want unfair criticism of a job well-done, I'll ask my clients to pay up. That's primo Gonzo humor you're tut-tutting and you paid exactly nothing to enjoy it. Y'know who else was a cheap ingrate? HITLER! Why ya gotta by like Hitler, Moonsammy -- IF THAT IS YOUR REAL NAME. I have my doubts on this topic, by the way.

Hey, what's Bob up to? I always enjoy a cheap laugh at the expense of the less fortunate.

(seriously dude -- I can hold 1:1 with a Clydesdale for an hour and have enough left in the tank to draw a standing ovation at Centurylink Field.)

You outright liar. (Nothing new)

Since you claimed you HEAR a beat BEFORE it can be SEEN, which is 100% backwards and something someone in the field should definitely know, you've been silent on that thread, hiding from your mistakes as usual.

Yes, facts are correct, you just didn't offer any. You gave your opinion based on ....who knows what, not medical science. Not reality.

You did not prove a thing, you rambled, listed your alleged career, claimed knowing doctors doesn't make you one, then said you know what your talking about because you know lots of doctors, etc. You gave no citations or backup for your claims, that there's a heart at 6 weeks, claims which I contradicted with multiple citations from medical sites, including instructions for the Doppler that contradicts you too.

You were proven wrong, and as usual you just hid from the thread. Try again.

And Kevin Bacon was in Footloose…

I would rather be thought an elitist by middle school dropouts who think they know everything but in reality are 100% wrong >98% of the time and partially wrong the rest of the time than be one of them.
Elitist!?! Lol. Are we back in 2016!? What do you think that word means?
Elitist: https://www.merriam-webster.com/dictionary/elitist
a: giving special treatment and advantages to wealthy and powerful people
b: regarding other people as inferior because they lack power, wealth, or status
That hardly fits, I think the rich should pay MORE by percentage of income, not LESS. Technically "special treatment", but definitely not more advantages.

Q: Do you think Trump is elitist? Explain your answer. (Pretty sure you just decided elitism is good).

If you would read, and not just insanity that agrees with your preconceptions, if you weren't so smarmy and dismissive whenever you THINK you have some point to make or gotcha tidbit of data, acting like a third grader who just took the last desert at lunch taunting the next in line, your bad grammar wouldn't get you ridiculed so often and you would be far less aggressive about making your mistaken points, and would again receive less ridicule.

But instead you swing nonsense with vitriol and hate like a club, clearly trying to do damage, but your club is a fake made of foam rubber lies, making it impossible to not smack you down every time you try to knock someone out with it and stand dumbstruck that it bounced back into your face.
If you're gonna be dumb, you better be tough.-Jackass

This time you're again wrong about what you claim, you backed yourself into a corner by claiming this IS your area of expertise and by deriding others without personal hands on experience in the field, then you got the facts completely backwards....as usual...then hid from your mistakes....as usual.

Again, I'll ask for 3 examples of that 1/3 of what I say that's wrong. I post enough that you should be able to find 3 from yesterday alone. I don't really expect you'll answer, because I don't think you can.

Lol....and we're supposed to think you know about it? Then why don't you? Why didn't you just read instead of eating more shoe? (By putting your foot in your mouth again)

"Beating occurs earlier, at the very end of the fifth week or at the start of the sixth week, when the heart is immature and lacks most of its identifiable features, including its iconic chambers. The heartbeat shows up around this time or shortly after as a flickering motion on an ultrasound. Only later, after the 10th week or beyond, is a heartbeat audible with a Doppler fetal monitor."

Derp.

Now that again you're proven wrong, having it backwards as you so often do, with citation and medical fact contradicting you, can you admit it? Doubt it, small men never can admit they're wrong. I admitted my mistake just one post ago.

If you expect you won't remember the person you've spent a decade arguing with in just four years, you must already be showing signs of Alzheimer's. I'm so sorry.

Edit: claim to be an expert!? When did I claim to be an expert? I'm pretty certain that's another delusion, but I'm certainly open to proof, which should be easy to come by if you aren't making things again. By tomorrow please. The only thing I'm an expert about is being a seriously cheap bastard.
This is pretty basic stuff, not advanced or really in contention medically, only as a political ploy...no expertise needed to know there's no heart at 6 weeks, or to read that you see the twitch 4-6+ weeks BEFORE it can be heard by dopler...a basic fact which I remind you that you, self designated expert in the field, got backwards. You were so sure about it too.

Really...You saw a HEART beating at 6 weeks. You're a liar....not a new revelation btw. You've been a proud liar for years.

The American College of Obstetricians and Gynecologists also has said in a statement, “What is interpreted as a heartbeat in these bills is actually electrically-induced flickering of a portion of the fetal tissue that will become the heart as the embryo develops. Thus, ACOG does not use the term ‘heartbeat’ to describe these legislative bans on abortion because it is misleading language, out of step with the anatomical and clinical realities of that stage of pregnancy.”

I do not believe you work in as a medical device service tech (which wouldn't include ANY medical training, now would it) but can't spell or read above a third grade level. It's just not believable....not that it would indicate any medical knowledge if true.

Again, seeing a PULSE is not seeing a heartbeat. If they say they saw a heart at 6 weeks, report them, they're delusional. What they call it has nothing to do with reality....many nurses are anti vaxers Q followers, being in the medical field doesn't make one reasonable, logical, or right. Techs aren't doctors....and doctors fudge the truth to avoid conflict. Press them, they'll admit there's no heart, unless like you they prefer a comfortable lie to the hard truth, and believe it's better to tell a lie than a truth that might hurt your position. Probably shouldn't have admitted you think that.

Here's a citation for you to dismiss as fake news....https://www.factcheck.org/2019/07/when-are-heartbeats-audible-during-pregnancy/

Btw, I stand corrected, except for changes in the muscle tissue, the basic heart is apparently formed by week 13, not 20. The muscle tissue matures around week 20. I'm always willing to admit when I'm wrong, unlike some.

@noseeem

Yep I'm shitty with grammar and spelling But I can fix anything and hold my own in front any Dr. or C suite within my field of expertise.

Personal experience? BSEET Penn State.
33 years as a medical Field service Engineer.


28 years working for Global conglomerates and 5 years in house at UNC Chapel hill NC.
I’ve been with Siemens Medical and General Electric most of my career.
I’ve serviced/ install Cathlabs, Vascular labs, Rad/ RF rooms and Mammo rooms. Plus others.


Last 20 years installing / servicing Medical Ultrasound.
This includes Cardiac, Radiology ultrasound and Woman’s health, OBGYN
I’ve seen more ultrasounds hearts and heartbeats than you can imagine..
Being Hippa compliant, I look at images for quality and for servicing.

All the Techs I talk to say the same . Heartbeat starts about the 6 to 10 week of pregnancy
And yes there are images that capture this along with all the other images and measurements. Doppler is used for this.

Per quick Google search
When does the heartbeat show on ultrasound?
A fetal heartbeat may first be detected by a vaginal ultrasound as early as 5 1/2 to 6 weeks after gestation. That's when a fetal pole, the first visible sign of a developing embryo, can sometimes be seen. But between 6 1/2 to 7 weeks after gestation, a heartbeat can be better assessed.

Your fucking up the wrong tree today. Go back to being the big guy at you high school.

You can even do this at home

Right after Jackass came out, a couple of friends-of-a-friend decided to stage their own version of the movie -- with a hornet's nest. They found the thing hanging from a tree at the edge of a field and it was not remotely on the small size. Also, this was in late August and the queen had already flown away, leaving the drones to slowly starve to death. Thus, the enormous number of stripey-stripey sting-stings were already good 'n' pissed-off.

They were about to get moreso.

So chowderhead A and chowderhead B have a brilliant plan: they're going to shoot this enormous ball full of astoundingly-irate murderous insects with a shotgun while they're filming it. If you're hearing banjos playing and luke-warm cheap beers being cracked open, you're about in the right frame of mind.

Places, everybody!

The stage is set: on one end, at what's decided to be "minimum safe distance", are our erstwhile David Attenborough/Jonny Knoxville knock-offs. At a decidedly NOT minimum safe distance away is the arthropod version of the T'sar Bomba. All we're missing now is a Mossberg, enough idiocy to think this can end any way but badly, and a camera. With far too much alacrity for what's about to happen, all three are provided.

Aaaaaand, ACTION!

* BOOOM! *

At first, surprisingly, nothing happens. This period of stasis lasts roughly a picosecond. Then, unsurprisingly, things start to happen and they happen far more quickly than the Chuckle Brothers planned on. This plays out in three acts:

Act 1: "Hey, uh, why is the nest still there?"
Act 2: "Uh-oh..."
Act 3: "FUCK FUCK FUCK FUCK FUCK FUCK FUCK!!!"

Hubris takes many forms, and schadenfreude takes twice as many, but both combined were statistically zero compared to the number of hornets involved in this fiasco. Had the two Mensa escapees who irked said hornets thought this thing through -- stop laughing -- perhaps they would have arrived at the conclusion that 1. a shotgun slug is not the preferred load-out when dealing with a ball made out of wasp puke and 2. being the only two things visible within a 20 mile radius of the ball made out of wasp puke pretty much negates the mystery of who the hornets are going to sting the ever-loving fuck out of.

With their plans in ruins and the nest not, our heroes decide to quit the field. This is the first smart thing they've done since looking at that big ball of wasps and deciding it was redolent with untapped hilarity. The hornets are having none of this white flag nonsense, however, and they decide to quit screwing around and really inflict some pain. It's a quarter mile back to the car and the hornets are going to make them pay for every inch of it.

The final score:
Hornet losses: meh, they were all going to die in a few weeks anyway.
The chucklenuts: 23 stings, a dropped shotgun, and three minutes of footage that they took in the pre-YouTube era and thus is lost to time.

Moral:
Hornets are not toys.

Imagine thinking the US would not intervene when China takes Taiwan...

At best the US could field 500k troops offshore without weakening other strategic locations.

China's paramilitary has 20,854,000 troops, as of 2018...
If they decided to do conscription that will probably add another 30 - 40 million.

Good luck taking that on without a draft to bolster the US numbers.

The US haven't won a war since they lost to rice farmers in Vietnam. Must be your achilles heel considering you lost against goat farmers in Afghan. Hope you do better against something more equipped that farmers...
