Shall we start by noting that neither magnesium nor zinc are vitamins > They are minerals. Now I agree that the information is designed to impress the punters rather than inform them. So look at the zinc citrate dihydrate. This is a better description because crystals of salts require what is known as 'water of crystallization' to form. This water is made of water molecules incorporated in the crystal structure. The dihydrate tells us that there are 2 molecules of water for every molucule of zinc citrate. So when reporting the weight of the stuff this includes this weight of this water. Now looking at the Magesium citrate this presents an immediate problem as they have not told us how much water there is. A quick google search reveals that there is a lot of it. Note that the molecular weight declared by google as 214 g/mol is much less than the official government value of 451 g/mol I'm sorry Im not familiar with US government labelling practice and terminology so someone else will need to help with refernce intake and nutrient reference values.

I'm not sure about squid, octpi and cuttlefish but I learned recently that jellyfish have no brain.

It is often said that examinations in the human world are a test of memory not of learning or intelligence. So is learning necessary for artificial intelligence ?

Pick you up 8 o'clock.

I agree. +1 I further think that a design need not be as complicated as an ant colony. My pepper and paper automatic leyline generator would suffice.

Do you not need to deal with the theory of physical wetting in your role as s circuit board designer ? This is an subject with little mystery and well defined properties.

Notaries are not as common in the UK as where you obviously are. One of my friends who is a solicitor also has a notary qualification, for which he had to do an extra course and examination. In lean times, and there have been many in recent years in the legal world, that brought in useful extra income as most solicitors are not so qualified. There are also other officials who offer officially certified copies of particular official documents. In the Uk these officials are often known as registrars, as we have many different registers. Of late, like other departments of government, they have tried to extract as much money as possible through fees.

I sincerly hope this is not another preaching attempt, so I will take your question as genuine. You might find reading Marcus Du Sautoy's book interesting in answer to your question Other books of interest might be the wooden books series,particarly sacred deometry by Mirand Lundy and Symmetry by David Wade https://woodenbooks.com/index.php

I posted this excerpt from ellenberg whcih explains the essence of language models.

Why do you say this ? There was nothing in my example to suggest it. Yes, this is more the gist of what I was trying to get to. Note time (small t) in these posts tends to refer to relativistic time. Whereas my 'time' is Time (big T). But this would suggest an axis not defined by relativity (??) and I think we need to be very careful here. Time is not a coordinate in spacetime as @Halc implies. And my description does not even make it a coordinate. @julius2 One of your other respondents asked if this was more properly a question in cosmology and Astronomy since you seem to want to concentrate on bangs, but you haven't expanded on this or helped me choose an appropriate level to pitch a response.

Thanks and I agree that CHATGPT is a language model. How many know what that means ? However I think @swansont deserves the credit for the quote here.

One factor not yet considered here is the age of the car. Electric cars have only really started selling in volume about 2 years ago. Before that it was only specialist and nich market stuff. In order to grow their market volume ev manufactures have been offerening discount insurance to buyers of their new vehicles. A couple of years on and those owners now looking around for a better deal may well have a shock. As a matter of interest Kia include a 5 year repair deal so the sot of parts may not be such as factor, They also claim that their own insurance prices for IC and EV vehicles are very similar.

Good morning Julius and welcome. I see that the response to your question so far has been rather cool. Perhaps you are a youngster just beginning to think about such things, perhaps you are older and still thinking about such things. Either way thinking is good. So don't be put off by the adverse replies the members are only trying to help. One way to think about this is to regard time as what mathematicians call a functional parameter. When we have several independent variables a parameter is a single variable that allows us to tie them all together by means of some formula (or function) between the parameter and each variable. The Universe is Space which has 3 dimensions. That means that we need three independant variables to refer to any part of that space, usually x,y and z. Time can then be considered as a parameter that specifies where in Space an event occurs, by means of some formula such that x, y and z are individual functions of the t parameter. Time is so useful as a parameter that the symbol for a parameter is usually t. Here is a simpler example in 2 dimensions. The standard equations for a parabola are a = at2 ; y = 2at. Ask if you want more detail or dicussion. Be warned also that as an anti spam measure new members are only allowed 5 posts in their first 24 hours. Afer that it is unlimited so long sas you are reasonable in what you post.

It seems to me that that this question might be resolvable depending upon the response of an AI to something it has not been taught. For example I don't believe a human would have much trouble understanding this One of the earlist proposed uses for AI is as a robot driver. So what would such a driver's response be to the following

So just exactly how common is it with references. I would suggest distinguishing between how common in settled communities, like say Denmark and war zones like the setting for your video. But fundamentally people need to take more responsibility for and care their own actions. How does the frequency of this type of misadventure compare with say the frequency of an ordinary joe clearing the rubbish bins or alleys and receiving an unwanted 'needlestick injury' ?

You have omitted one of the dimensions of energy. Actually one thing Markus has not stressed is that Using coordinates directly does not satisfy the Principle of Relativity. You need to use coordinate differences for that. It is also worth realising that n dimensional coordinate rquire n+1 pieces of information (unlike geodesics for instance ) I totallty agree. Relativity cannot cope with singularities. It is interesting to note that, as you say, such singularities arise in Fluid Mechanics and Nature has its own resolution, not predicted in the mathematics on eithe side of a singularity. Shock waves and the Hydraulic jump are specific real world examples, and energy is involved in the analysis.

Still waiting for your reply. I feel like the pupil who carved onto a desk in my school In Honour of those who died waiting for the bell

I can't imagine the subject which offers these examples as risk assessments. I agree that the examples you quote are a long way from what I understand by the risk assessment process. There are several different forms of risk assessment, depending upon the intended purpose of the assessment. But all depend upon identifying all the risks and assigning a probability to each one as well as a second parameter known as the severity. Roughly this means the cost of being wrong. Formally it says that given the event at risk actually happens, what would be the consequences - would it actually matter ? The implementation then becomes a matter of the statistics of conditional probability. Finally an assessment of reducing or removing the identified risks is often appended at the end, particularly in Health and Safety matters. Here are some examples Compare the risk assessment for a Nurse and a Seamstress pricking themselves with a needle. 1) A seamstress gives herself a slight prick with a sewing needle. Assessment There may be some short term pain but it is a common occurrence usually resulting in no harm. Possible solution Use a thimble. 2) A nurse pricks slips and pricks herself with a hypodermic needle she has just used to inject a patient. Assessment Risk transferring to herself a dangerous drug or dangerous disease(from the patient) such as HIV or Hepatitis. Consequences can be severe - death or serious injury. Possible solution Use an automatic self retracting injection device. A second place formal risk assment appears is in engineering in what is known as Limit State Design. Here the objective is to produce a known and acceptably low probability of failure of an engineering design by statistically combining what are known as partial safety factors. So tell us what the actual question is that you have been set, for more help, since this is Homework.

something like this is used in engineering, including computer engineering. They are called heat pipes. https://en.wikipedia.org/wiki/Heat_pipe

Sure. But beware og these EVs https://www.bbc.co.uk/news/uk-scotland-67005620

Did you miss my last post ? The Uk electricity supply is 230 volts at 13 amps single phase from a single domestic socket. That gives you 3kVA. More power can be had by using a dedicated 30 amp supply, still at 230 volts. That is equivalent to one ring main direct wiring from a single fuseway in the box. This is nearly 7.5 kVA and is used for say 8 kVA instantaneous showers. However the charging lead for my brother's car, like most uk electric vehicles limit the input current to 10 amps at 230 volts. So your neighbour has 9 kVA in good daylight. Jolly good if he is a night worker and charges hois car in the day otherwise he would have to layout for storage capacity equal to a day's charge, if he wanted to work in the day and sleep at night. say anothe £15000 on top of the panels and vehicle. In which case the EV would be more efficient, if you returned to base between trips. My other brother is on his second hybrid with a 25 - 30 mile range and does mostly short local trips like you do. Mainly the batery allows the vehicle to half its fuel consumption or double the miles per litre. This is again competitive with all electric. Some thread back I published an efficiency graph for an EV battery, here at SF. Their optimum temperature is 23oC, although the fall off is much less severe at higher temperatures it is still less efficinet at 30 than 23.

I see no response to my comments. How Christian is that ?

So your question has nothing to do with golliwogs per square root of carrot or any other strange measurement unit. Unfortunately real life is more complicated than your wish, especially as no one yet knows the 'carbon cost' of electric vehicles, which must vary according to your source of electricity. Here are some real world figures from England. Petrol My car does approximately 9.3 miles per litre, pretty reliably since I do very few journeys of less than 10 miles. Petrol in Bristol and Plymouth are usually about £0.1 per litre more expensive than where I live, so I prefer to fill up near home. My tank holds about 35 litres which give me a range of 325 miles. Electricity My brother's car does about 4.3 miles per kWH but that can decrease by 50 % in worst driving conditions (winter, very wet, night time) It should be remembered that all the auxiliary machinery in an electric car (heater, wipers, lights etc) are run from the battery which is the only energy source. Now here comes the awkward bit. When my brother visits he pay me £0.3 per kWH to plug into my english mains and recharge. His car has a capacity of 64kWH but this can only be achieved with heavy duty 3 phase industrial supplies. Lesser supplies can only charge up to 80% that is 51 kWH. The commercial cost of electricity varies from £about £0.5 to £0.8 per kWH. but only the most expensive will achieve a recharge time of 30 mimnutes (as compared to 3 minutes for filling my car). Further my brothers car currently attract zero road fund licence (tax) compared to my several hundred pounds. Also petrol is heavily taxed in England, far more so than elctricity. Heaven only knows what it will cost to run an electric car taxwise when the chancellor has forced everyone into them. My mains supply takes over 24 hours to fully recharge his car from flat. So there you have it. Some facts and fiures from the last 3 years driving experience.

I didn't say it did. But I also indicated that clearing up the OP misunderstandings about units in general would help bring clarity to the question.
