When hospitals install MRI machines, costing millions of dollars each, there is no measurable improvement in patient outcomes.
Really? And just what other diagnostic equipment can be used to differentiate malignant vs. benign tumors? I guess you can irradiate the patient with a CT scan and then do a biopsy to figure it out. While a CT scan is probably cheaper by itself, I don't think it will be once you add in the biopsy. Then the ionizing radiation and the possibility of complications from the biopsy, I'll take the MRI.
What do you suggest we use to look at white matter lesions in the brain? I'm sure Alzheimer's and MS patients would like to know. Well, the early onset Alzheimer's patients anyhow.
How about soft tissue injuries? What do you propose we replace MRI with for tendon injuries? Or spinal cord injuries?
Sure you can do a cardiac function and flow analysis using Echo, and a SPECT scan for perfusion and CT to look at the coronary's, and possibly infarct imaging. The CT actually does a better job of the coronary imaging too. Or you can do a cardiac MRI and get all of those and a hell of a lot better imaging in every case with the exception of the CTA.
no need to wait in line or even speak to another human being.
There's nothing like technology for bringing people together. I guess I'm guess getting old, but I thought part of living in a society was to talk with other people. It's bad enough that we can now get all of our news from sources that reinforce our viewpoint and don't introduce us to different opinions. But something like this means the start of not even needing to worry about taking to anyone that we don't' want to. Perhaps this is also part of the reason that autism is on the rise. It certainly won't help if we can start ignoring even more people.
In most jurisdictions you can't by alcohol after a certain time of day.
Strange, I've been in most US states and always thought the opposite was the case. But I haven't drank alcohol much for a good many years now. So I don't really pay attention that closely anymore. Perhaps it was different a couple decades ago. Other than the states with large Mormon populations, I didn't think this was the case in most states.
From the Summary:
>English has become the undisputed lingua franca
I wonder if they know what that means... or if they were going for that on purpose.
I wonder if the author also confuses words like pizza and lasagna as being English words.
That's because pizza and lasagna are English words. Just like every word in this sentence, comprende? The English invented language. The English had Shakespeare and Socrates. Homer and Hemingway. If you go back and look at pictures of London from a million years ago, they had steam engines and skyscrapers, while the rest of the world was living in mud huts and grunting.
The English had computers in 1837. At that time America didn't even have roads and people fought over such primitive things like cattle or religion. Since we're talking about science, you know that Darwin guy that invented atheism? He was English.
IÃ(TM)m pretty sure they donÃ(TM)t sell the Ãoeballoon gasà at Walmart by the liter.
Did anyone say they were looking at it at Walmart? I did a simple Google search for the price of a liter of liquid helium and it came up with a price of $5. I'm also guessing that was what the OP did to get that $5 price per liter. But that is not the same grade of He that's used in a magnet.
Might not be all that safe though.
No, it's not. If you cracked that open you could pretty easily asphyxiate everyone in the house.
What grade helium are you talking about. The stuff you use for balloons is a much lower grade and much cheaper than what is used in a MRI scanner. He for a scanner was $5 back in 2010. That's not what it costs currently.
No recovery effort could possibly be cost effective for such a small leak
Most scanners that were built in the last 20 years do recover the He that leaks out as part of their normal operations. But you can't capture it when you need to quench the scanner. It's simply not safe to do. He displaces oxygen 28:1. With a typical magnet using 2000 liters of helium, you don't fuck around during a quench because you are likely to asphyxiate a lot of people.
Because they're idiots who don't realize what they're dealing with, that's why.
The only way to prevent such waste is to increase the price of helium to such a point that everyone dealing with helium, when possible, will try to re-capture it once it's been used.
Helium prices have increased a lot actually. In 2010 it was about $5 per liter. Which was pretty high considering it was about a third of that in 2006. In 2016 it was $17.35 per liter. I don't know what the cost is currently. Depending on where you live and when you needed it, in the last year it's ranged from $10 to $70 per liter.
Most scanners from the last 20 years do recapture as much He as possible. But still lose some. Philips has a new scanner that is sealed and supposedly does not need to be topped off ever. But I'm not sure how that works. He has is very good at finding a way to escape. I belive that the Philips scanner only uses 20 liters of liquid He. A standard scanner can use 1500 to 3000 liters.
I don't know what happened at this site, but things can go wrong when you're ramping a magnet up. They may have needed to do a partial quench. It wasn't a full quench or there would have been a hell of a lot more than 120 liters of gas. If they were using an old vent pipe from a prior magnet, then who knows what could have been in there. Birds like to build nests. Sometimes when there's too much humidity in the air, ice can form and block or partially block the vent. When a quench happens it takes about 1 minute for 2000 liters of liquid He to convert into gas.
The human lawyers outlawed AI lawyers. It took the human lawyers and average of 2.3 seconds to get the law passed. The AI lawyer objected within 1.4 nanoseconds. It was overruled by the human judge and the AI lawyer was summarily executed/unplugged.
Your average sensor, some of which are are just POTs, can be a couple hundred dollars a piece. Inductive sensors, about $400. A little bit of electronics knowledge can save a fair amount of money by making off-the-shelf parts from various automation retailers do the same job
I had to fix the electric door lock on the passengers side of one of my cars a couple years ago. Of course the power locks, power windows and power mirrors all connected to the same door module. It was $500 for a new door module. It was a relay on the module that had gone bad. Since there were three of them on there I ordered 6 new relays from an electronics company for $20 for all 6 and removed the old relays and soldered in the new ones. I have three more in case the drivers side ones go bad. But saved $480 dollars and spent about an hour of my time.
For cars, though, it's more complicated. The other day I learned that to change the headlight bulb on my sisters vehicle it requires removing part of the cowling inside the wheel well. And if you need access to the other lights, it requires removing the bumper!
Wow, that's a piss poor design. What kind of car was it? I want to be sure to never think about buying one.
Isn't this just a "solved game" already? Aren't there AIs out there that can perfectly beat anyone at Tetris? Once this is true, what is the point of playing?
Yes, a can opener can open a can better than you, a front end loader can move more dirt than you, and a car can move faster than you. So just kill yourself now. What's the point in living?
Or maybe you can strive to be the best you can be at whatever you do and not worry about it. Hell, there's a lot of physical activity that I can't do anywhere near as well now as I could do in my 20's and 30's. I still lift weights and do cardio, but nothing like I could do back then. But it doesn't mean I'm going to stop.
The best way of "engaging schools and students in engineering" is to involve them in solving real world problems that will benefit many people. This isn't doing that.
Sure it is. With a fleet of these cars I can finally open up a home delivery taco business. Without this car, the taco shells always get soggy by the time they arrive.
At this point it's unlikely he would be killed. He's now effectively been locked up. Why not just go to court and get it over with? He basically imprisoned himself and may end up still having to serve time if he leaves. What's the point?
The tech giants have a monopoly. Facebook, Microsoft, Apple, Google
You listed 4 companies. That doesn't sound like a monopoly to me.
Perhaps the OP meant they have a monopoly in their specific focus, not tech as a whole. Does any of the mentioned companies come close to competing with Google for search? Or Microsoft as a desktop OS? Or Facebook for social media?
I
don't recall Bell Telephone defending their monopoly because of CB radios, or ham radio, or cans attach by a string. The reason was a monopoly on telephone communication, not communication on general.
While I'm not a fan of Apple, I don't know how they can be considered to have a monopoly. Except for the waning reality distortion field of Mr. Jobs.
Ok, fine. We should call it "misuse if someone's likeness in a sexual manner" and force the guy register on a "misuse of someone's likeness in a sexual manner" database and to send out notifications to all if his neighbors that he misses people's likeness in a sexual manner.
Yeah, great idea. We should create a database for everyone. Anyone who speeds shouldn't be allowed to drive. We should put alcoholic and pot smokers on a list.too, or should we make a list for individual drugs? Anyone who can think should go on a list too, obviously they're a threat. You obviously need to be on the list of people who should be medicated.
While the sexual predator list sounded like a good idea in theory, in practice it's a fucking disaster. Some who gets caught taking a piss in the bushes doesn't belong on that list. It a biological function and we all have to do it. When did a picture of someone partially or fully naked become porn? Context matters. Or should we burn and destroy any art with nudity? Medical texts should also all be burned as porn right?
Stay the hell away from my daughter. Creep.
I never mentioned or have any interest on you daughter. Perhaps you're a little too obsessed with you own daughter and are projecting you mental health issues. It looks to me like you forgot your medication today
Using them in sexual videos without their consent should be considered sexual assult.
I'm all for protecting people from sexual assault and harm, but really? This is what you call assault? Let me guess, if someone looks at you and you don't want them to, you consider it sexual assault. This is the problem with calling everyone Hitler, or a racist, mysognist, pedophile, etc. After a while those words have no meaning and you have to amp it up even further.
How about we call it misuse of someone's likeness, or just plain rude and obnoxious. If there are laws against this, then they should be charged. But let's not go full tilt stupid.
Jeff Bezos predicted Monday thatÂwe'll have one trillion humans in the solar system one day
Unless things change a lot at some point, I don't see how that's going to happen. It's going to take a lot of tech advances if we going to somehow populate anything besides our current planet. It's becoming apparent that after a society reaches a certain level of advancement the population plateaus or even shrinks. Just look at Japan.
If this is in fact the case, then in order to keep growing the population, we're going to need a good size portion to not reach that point. In which case we're going to have a lot of fighting between different classes, races, tribes, and whatnot. Hell, just look at how the different political parties are with each other in the US right now. Unless something happens to change the curent trajectory, things are not going to get better
Then, if we somehow manage to actually populate somewhere else, how long will it take before the population of the moon, Mars, or whatever feel they are being treated unfairly by Earth? I would guess that once the population becomes self sufficient, or has a product that only they can supply they will want independance. That seems to be the way of things here on earth. At least historically. If that turns into a war, then someone could start lobbing rocks from above,. Which won't turn out well.
But all of that is moot until we over come all of the technical hurdles. Which are not going to be easy in any way. Getting enough mass out of the earth's gravity well is going to be expensive. We could probably do that currently if there was enough public support. But needing to carry all of the stuff needed to survive is costly and no easy task. Surviving radiation once we leave the protection of earth's magnitosphere is also something we don't know how to do in a practical manner. If we manage all of that, we still need a way to keep a perpetual life support system going at the destination. Long term, it's likely that no one will ever be able to return to earth either. Anyone born on one of these colonies will not develop to do well in earth's environment.
I like science fiction as much as would be expected for someone on/. but we're not going to be leaving the planet to settle somewhere else any time soon. Not without some huge leaps in our technology. It'smore likely that we turn into a planet of Borg like lifeforms in order to grow our population to a trillion than we do so by colonizing other planets and moons.
Can you even imagine America executing a Trump or Clinton?
Prior to 10 to 15 years ago, no. But at the rate things have been going, I can see it happening in the next 5 to 10 years. The wing nuts have been getting ever crazier and have gotten very efficient at stirring up more people than I would have ever thought possible. The media has also gotten very good at giving the masses just enough information to scare the shit out of them, but not enough to make an informed decision. Even the weather channel hypes anything they can.

In practice, some three-letter agency or foreign power will steal them.

As long as the original owner doesn't loose the information, then it's not theft, right?
