Um no,she died from fumes.those cables put out 5 volts dc.4 amps.
As the entire cable was not burnt,it was not a short in block putting out 110volts ac.
Burning plastic fumes killed her.cyanide i suspect.
Um no,she died from fumes.No, she would need a lot of burnt cable for that to happen, and we can see only a small darker patch.
those cables put out 5 volts dc.4 amps.The cables can put out much more, and those cheap chargers made in China do not have good enough isolation. Years ago, a charger would have relatively large, heavy transformer, with the 110/230 V being isolated on the primary coil and the 5 V output isolated on the secondary coil.
As the entire cable was not burnt,it was not a short in block putting out 110volts ac.The short circuit would be inside the charger's box, not on the wires, and current strong enough to kill someone (0.5 A) wouldn't burn the cable on such a short time.
Burning plastic fumes killed her.cyanide i suspect.Electric wires are mostly made of PVC (polyvinyl chloride) or PE (polyethylene), and neither gives cyanide when burning. I don't know what gases PE gives when burning (although I know cyanide is not included, as it needs different chemical compounds present), but PVC gives hydrogen chloride, that is not lethal, although it turns to hydrochloric acid if it contacts water, so someone breathing hydrogen chloride would feel the effects of the hydrochloric acid but would not be killed by breathing it, unless it was a very big amount of gas.
I dont know the technical details on how the voltage is reduced down from what maybe a transformer within the charger to reduced voltage or current down from a 110/220 V mains supply..I do, I learned how to design and make both basic transformers and electronic battery chargers. :)
I was not sure if ArMaP or Robo or other members may had left , or been ill or gone on holiday... Not seen some members for a while...Things have been too slow lately, but, like Dr. Piers in that British TV show with Thermoman, "I'm always here". :)
That's a different problem, batteries get hot while charging, specially if they are not the original battery and, like most non-original cheaper batteries, have a lower capacity and are charged with the original charger.https://www.youtube.com/watch?v=EQQ1MWWf8ZQ

The video looks fake and the sound effects are clearly fake. Batteries do not really explode, they have fast burns that will create too much pressure and burst a package that doesn't let the gases out, but they do not explode like in the video.https://www.youtube.com/watch?v=Zm6mmzthFq0

I have always sincerely believed, that the mobile phone (particularly the smartphone) is a literally demonic form of technology.
I was not aware that you had some background in Electronics..More electrical engineering than electronics, but I did a mail course on digital electronics, after a six month intensive course on industrial electronics and automation.
Do or have you still or have work /ed in the Industry ?No, never. During that industrial electronics and automation course, in the automation part, I found out that I preferred software to hardware, and decided to learn even more about software, although I didn't had any course on that.
I am wondering why the Wires that they have used for such Phones or Tablets are so poor../ or appear to be relatively weak... As I mentioned I have or had two devices that both have had a problem with the wiring... in particular right near where the USB plug part or pin type end that goes into the device..In almost all electronic equipment, things like buttons and plugs are almost as expensive (or even more expensive) than the components, so the use cheaper products. Sometimes, it's not the plug or the wire that are not good enough, it's the workmanship of the connections between the two parts. For example, one thing I noticed is that most chargers use very flexible wires, similar to earplug wires, but when they connect a plug to those wires they do not put a protection around the wire, so the thin, flexible wire bends in the part in contact with the hard plug and starts breaking. They just had to add a plastic piece to protect the wire and bend slightly, so the wire wouldn't bend as much.

Was your courses Practical.. say in ref to wiring and building of electrical or circuit type components, or maybe Technical on how things work or the science behind components or circuits etc or both ArMaP ?Both. The mail course was slightly more theoretical, but I learned enough to design a basic CPU.
In ref to your Electonics Industrial / Automation... is that in ref to Robot type technology say in a car Manufacturer ...as well as any other Robotic type of product manufacturers ?Robots are just the part that moves, what makes them move is the automation part, so although we only worked with a small Siemens automation system (a Simatic S5, if I'm not mistaken), the principle for controlling a Lego crane (the best project on that course, they even appeared on a newspaper) is the same for controlling a complex robot: inputs, processing, outputs.
So, is software something that you have self taught yourself ?Yes, I am a self taught programmer.
such as programming ?
By any chance did you ever work in that area ?I have been working as a programmer in the last 22 years. :)
Robo also suggested that you have a Biology and Chemistry knowlwedge background....in which some of your posts suggest that you are quite aware in such related areas.... were they subjects that you took in School or college ? or that you just had an interest in and self taught / studied in certain areas ?I had Chemistry and Biology at school, but as they are subjects I like I use any opportunity I get to learn more, but I didn't study them to any meaningful detail.
It seems that you have a Science / electo engineering / computer background !I always liked science. :)
Both. The mail course was slightly more theoretical, but I learned enough to design a basic CPU.

I didn't read the whole thread, I presume she fell asleep in her bed with the thing; kids have their eyes mostly glued to the darn things, why they have to take them to bed is beyond me.
Is that even as far as doing miniture circuitary via Microscope type work ? :) or drawing out the circuits.. inc the various miniture components in a CPU ? or all ?I learned how to join the transistors to make logic gates and how to join those logic gates to create a programmable circuit. I also learned how to draw out the circuits, but the connections in modern CPUs are so complex that they are too complex to be made by humans. What I learned would be enough for me to be able to make a simple CPU, like one on a simple programmable calculator, but, without being able to make a chip with the circuit in it the CPU would probably need a big box for all those components and would use lots of energy.
When I referred to Robots...I meant the Electrical side of them... in relation to the circuitary or wiring to make the mechanical parts of Robots do their mechanical type movements in the various directions...I didn't learn that, that's more mechatronics than electronics. But the basis is sensors (simple contact switches, temperature sensors, cameras, etc.) and actuators (motors, electromagnets, hydraulic systems, etc.) and mechanics.
I assume you mean that you took those subjects into your later secondary School years at the end of year exam level ?No, before that, at the later years I only had subjects related to electricity.
It would had maybe also been good for you, if you had been able to study the subjects at a higher level..Time is always the biggest problem, 24 hours are too little for all the things I would like to do in a day. :)
but maybe your happy or prefer the programming side..I love programming, sometimes I get home at the end of the day and do some programming, just because I can. :D
Is your programming a combination of languages.. be it html...Php, or C+ or some other type of programming ?It's almost all done in Visual Basic or VB.net, with HTML (although I don't consider HTML programming) and Javascript when working on web pages. I never did anything in PHP or C+, but tried a little C++, but I didn't like it.
and in what sort of industry ? Would that be in engineering... / electrical oriented or things like systems, such as in companies or Banking...or Govt depts ?I work in a software house. Our main products are a program for historical archives and an invoicing program.
@armap,that highschool class must have been equivalent of a masters degree in usa college.or youre just really weird! Hmm? Lol!I don't know what class you are talking about, as I didn't specify any.

and no doubt the advanced Chips are now far beyond most peoples understanding..Today's chips are more like a full computer inside a chip than the chips from 20 years ago, and I think designing a chip these days must be similar to design a huge town like New York or Los Angeles from the start, designing all the roads, pipes, telecommunications, buildings, supporting infrastructures, etc.
They seems to continue to be smaller and smaller yet are able to deal with more complex data and also are faster..They can be faster because they are smaller, as the distance electricity has to travel is shorter. Also, being smaller they spend less energy, which allows them to use higher frequencies, that's why they try so hard to make them smaller.
I find some Electrical quite hard to understand..The basics are simple, but there are many formulas that need to be learned. On my penultimate secondary school year I had to remember more than 80 formulas, for Physics and Electricity classes.
Thats assuming the school system in Portugal is similar to the UK...I see by your description below that is not. :)
As in my last two years... I had to choose certain (6 or 7 or so) subjects to do for what we call GCSE or "O Level " or whats known as Ordinary Level exams.. which is what most peole have to refer to when they leave school and apply for jobs..I don't know if things still are as they were when I was in school, but at that time, in Portugal, from 12 to 18 years old we had 6 years of secondary school, the first two had mostly generic subjects and the last 4 were more specific, with the first of those 4 being dedicated more to a specific area (like technologies, languages, etc.), the next two dedicated to a specific subject of that area (like electricity, mechanics, etc.) and in the last one we could look into different subjects from the same area (I chose Geology, another subject I like). Then we had an exam, and if we had high enough results we could go to University. As I wasn't thinking about going to the University I din't bothered taking the exam.
Those who do well in those exams may then go on to do two more years at school or College to then do "A Levels" often to the age of 18 yrs old..
Then those who do well, may then go on to do degree at a Univerity... but there are other various ways one can do this if they did not do well in those exams at O or A Levels...
who may take college or night school or home studies to study for a degree in some subject they are interested in.
So is your abilities in Biology and Chemistry more based on your own later study.. combined with you recalling your earlier school years..I liked Chemistry a lot, but when I had Chemistry at school I didn't like it, I preferred Physics. Biology has been more an influence of my elder sister, she's the one that loves biology.
You must have a good memory and ability if you refer to what you may had learned in your earlier school years..
I think this was what Robo was referring to..I hope so, my highschool days are long gone but I didn't stop learning. As I use to say, learning is one of the few things you can do all your life. :)
That you may appear to have a much higher level of understanding than earlier highschool level...! ???
You must be keen on Programming if you still do your own after work...:)
Its a skill that you can apply to your own ideas.../ projects.I see programming as a way of putting computers doing what we want, so we are free to do other things, but also as a problem solving challenge, as we need to convert the information and how we work with it into something computers can work with.
Would you say Programming is more of a logical application ?
I would have though that Java is hard to do ! Is that to do with video or visual type things on a website..Java is one thing, Javascript is another. Java is similar to C++, while Javascript is much simpler and limited to a few functions to work with a web page. Java can be used to create whole programs or programs (applets) that run on a browser (although now most browsers block it), while Javascript can only be used on web pages, to do things like rotating an image, changing images based on a timer, validate user input, etc.
I meant to refer to C++...(not C+) and I believe it is one of the harder form to learn..so I could understand why you would not like it..I don't like languages like C++ not because they are difficult but because I think there are easier languages (like Visual Basic) that can do almost the same, and, being easier, we can work faster.
I think it could be interesting if your working say in some parts of History that would be of interest to you..Historical archives is where all the information from the past is stored. For example, the historical archive of the Portuguese army has records of all the military operations since the 16th century, only the more recent (usually 10 years old or less) are left in unit that created those records, as they be needed for present actions.
Or things like find your past ancestor websites...
I assume also Maths and Portugese or a Language (Maybe even English )as also being Compulsionary ...I had Maths in all years, and it was the source of my problems, as I had to repeat two years because of Maths. Portuguese and one foreign language were compulsory, but the language was French, English was presented the first time as an option then, but as I was not interested in spending more time at school I didn't took English classes.
Other subjects like History , Geography .. are usually choices..I had those too.
Then there maybe a type craft subject.. metal work, wood work... or Technical drawing... or maybe in more later years... information technology..When I was at school (I left in 1983) there weren't any information technology classes, any thing related to computers was only available in universities, part, if I'm not mistaken, of electronic engineering.
but its very hard to say for sure... as it can be that some people just were not in the right position to have been able to study harder topics if they had not been given a good start in life or if they had various problems in their earlier life..From what I have seen, the problem most people have with some study subjects is that they do not find them interesting, as when people find something they like they can take the time and work needed to get good results. It's like Maths, most students don't see why they should learn all those things about second degree equations and imaginary numbers and such things, but I think that if the schools started by showing some final result (a computer game, a jet fighter, whatever) the students found interesting and then showed how the Maths were behind those things some would look at Maths in a different way.
But I do think ... we all have set abilities in certain areas..I think that's natural, if all people were good at the same things that would mean that all people would be bad at the same things, and as a species our chances of evolution would be worse. For example, physically, some are faster, some can carry more weight, but those that can carry more weight cannot be fast and the fast cannot carry more weight.
and we are not capable of doing certain things..or we all have a limitation eventually..
Ive read some surgeons have IQs of 220..Surgeons don't need to have a higher IQ to be surgeons, they need to learn a little more than GP doctors but need to have an excellent control of their motions. My elder sister has a small company in which she gives art classes (she has an art degree), and one of her students is a surgeon, and she says that it's impressive the kind of control he has over his hands, he can do exactly what he wants with them, but, sometimes, he isn't capable of painting like he should, not because he cannot do it physically but because he doesn't understand what he needs to do to achieve the result he wants.
where as a GP Doctor may only have a 160 IQ and even they could never become surgeons..
let alone a average person with a average 100 IQ...who would have no chance what so ever..IQ is not everything, it's just a way of measuring something, different kinds of tests give different results, and without a clear definition of "intelligence" they cannot really measure it.
that seems how life is.. just a lottery. !
I think its down to luck, genetics or maybe past diet in ones parents / ancestery..as well as upbringing..and fate ! :)I think that's partially true, but, as I said above, part is because people don't see a good reason to follow the studying of a specific topic, either because they don't see how they could get a better job because of it or because they cannot spend the time to make the course, as they need to work.

One thing that helps getting a degree in things like law and medicine is a good memory, as much of what they learn are things they need to memorise, that's why those subjects are the best for AI systems.

In terms of education.. and Jobs... I think most is a mental thing rather than physical.. and to do with our mental abilities and mental strength as to how we are able to deal with things..That's why children should have freedom to chose what they want but with the support of an adult to try to identify what they are good at, so if a child wants to be, for example, a mechanical engineer but shows aptitude for biology, they can show that, if they cannot succeed at mechanical engineering then they could try biology. Sometimes people do not even notice that they are good at something because that's not what they are expecting (or wanting).
but there can be many obsticles that can cause us problems that many a time we just had no idea or knowledge about in how best to deal with.. that can have negative effects on us...
It may depend what type of Surgeon... but I believe on average that that do need a higher IQ than a General Doctor..Why do they need to be more intelligent?
but I found it hard to believe the suggestion in something that I read that it would be as high as over 200.. when it was estimated that a average Doctors IQ would be 160...Those estimations sound more like preconceived ideas about jobs.
or a Dentist 140..to give us some idea !
BUT I do wonder how well or better we all could do given the right guidence / upbringing and education..Exactly. The problem is that most professors are just waiting for their paycheck and not worried about the students' future, the few that are can really make a difference.
Ive read certain things that could be down to biology and just what we are given in terms of our development, rathen than how hard we try.. so for some its just more natural.. or easy for them... obviously some of us will have mental issues.. or have been effected by various things .. be it stress, or vaccines or drugs.. or food and water issues as Alex jones suggests..Food makes a big difference, as a child that does not have a good diet cannot have a good development and will never be as good as they could have been.
but doing well or ok in a IQ tests may not apply to us doing well in Life.. plus everything is relative...I think the only thing a IQ test shows is how easy it would be for someone to learn something new, but to really learn that person also needs intention, someone with a high IQ but too lazy may use their intelligence to avoid doing any work.
It is suggested that IQ can also often be a measure of what we may earn in our jobs or what jobs we may get..See above.
which determines our future..
OccupationThat list is silly. For example, a mathematician needs to know all the math (and more) that any of the engineering jobs above on the list need to know.
IQ
1. Surgeon
234.1
2. Physician
161.1
Why do they (Surgeons )need to be more intelligent?
Those estimations sound more like preconceived ideas about jobs.
Exactly. The problem is that most professors are just waiting for their paycheck and not worried about the students' future, the few that are can really make a difference.
That list is silly. For example, a mathematician needs to know all the math (and more) that any of the engineering jobs above on the list need to know.
It looks more like an income list translated to an IQ list.
PS: Einstein was a theoretical physicist, something not listed. Physicists are on number 12 on that list. :P
PPS: after a little Internet search, it looks like one of the people with highest IQ ever recorded is a Korean civil engineer, Kim Ung-yong. Surgeons do not appear in any list of high IQ people.
I think we all respect or look up to Doctors..I don't, to me they are just another type of worker, with some bad and some good, some that follow that career to help people and some to just get more money and respect.
In terms of why would a Surgeon be required to be of such higher Intellegence... is because their job demands it...All doctors need to know that, there's nothing special (as far as I know) that a surgeon needs to study that other (specialized) doctors do not have to study.
They have to know and be good at all the Sciences...
that includes Biology, Chemisty and Physics or other things related..and Mathematics and good communication..
In terms of the Sciences.. I always thought that Id read that Biology was the hardest of the main 3 Sciences....Biology must be hard, as the basis is Chemistry, so they also need to learn Chemistry (I suppose), but only the part of Chemistry that is related to biology. Physics must also be hard, as it applies to every physical aspects of the world around us.
I think you could also include a reasonable level of Chemistry and Physics as being required in the subject..
But I also think Chemistry is hard to learn..I found it hard to learn at school, as I couldn't find any logic behind it.
