Wow, I guess our schools were more strict. In 7th grade we had Algebra, then in 8th grade Advanced Algebra with a touch into Geometry. Catholic High school started with Advanced Algebra first session, then Geometry.
When I switched to Public School for my Sophomore year, they were still on Advanced Algebra. Geometry in Junior year, and Trig in Senior, or Advanced Geometry, which is what I took my senior year. But that wasn't the only math they taught. We did have accounting and finance, plus formulas for chemistry, etc. If you took Chemistry, they taught math there too.

All of my years in Catholic School, or day started with going to Mass first. Then one of our classes during the day was Bible Study, which was often combined with some Geography, History, all revolving around our religion of course.
Then of course, Math, English, History, Geography, Sciences, etc.
However, unlike high school where you went from class to class, in grade school it was all in the same room, but sometimes by different teachers after 5th grade. But even so, every school seemed to work differently.
Where my two sisters went to school, they had a different teacher for every class, but in the same room.
They had chalkboards on two walls too. And all the kids had to turn their desks after lunch to the other wall.
I think partly had to do with how the sun hit the building and windows that got this started, hi hi.

I didn't get that good of grades in school, but was always a class ahead of the one I was in after 5th grade anyhow.
But some law prevented me from moving ahead one class. Apparently that was only possible between 3rd up to 4th, or 4th up to 5th. But they didn't allow 5th to move up to 6th. So I basically aced all of my tests in 5th grade, even though I goofed off a lot, hi hi.
I wasn't necessarily smarter, I just went to a school who's teaching level was a class ahead of most other schools.

I heard of kids skipping a grade when I was in school but I'm not sure if the stores came from the public schools or the parochial schools. All I know is that it did happen at the grammar school level. There were certain classes for each year in high school, but if you were on the Honor Roll you got to take classes not available to the average students. Calculus was one of those a freshman could have taken if they had the right background. All I was offered was algebra. Public schools were more regimented because, after all, they were public. Everybody got the same treatment. That was only a general assumption in the Catholic school system which always considered themselves well ahead of the public schools. That might have been true in general, but as I mentioned earlier I didn't get much math or science in grammar school. Just the basics if any at all.

I knew a gal much like yourself. She didn't need to study much and hardly ever did homework. She aced every class. She did almost the same as a freshman in college and decided she should be a lawyer. They accepted her in law school but after a year they asked her to leave. She wasn't lawyer material, she was told. That devastated her and after about a year she went into nurse's training. I lost track of her after that. This young lady was brilliant, but only under certain circumstances apparently.

I only went to school 33 days my entire senior year, hi hi.
I did go in to take the tests when they had them in each class, and would often spend the day.
But like your friend, I was able to ace the tests, but got a big fat zero for the days I wasn't there.
Come mid-semester exams, and later our final exams, I did study up a bit for them.
Can't say I aced them, but I did get in the upper 80's on every one of them, and in the low 90's on a couple others.

I think one of the reasons, although I am poor at math, I knew so much about math in my early years, before my time, has to do with being raised in business environment that required a lot of math for nearly everything.
As a youngster, I helped unload the trucks of inventory items, took the invoices for them, added inbound freight, then divided that out by the number of pieces of an item. From that figure I added our different percentage markups for how they were sold, either wholesale or retail. In case lots, carton lots, or by units.
So doing this since I was knee high to a grasshopper, things like fractions, decimals, and percentages were easy for me in grade school.
Ironically, I did poorly in Algebra, but shined in Geometry. Seems I had a sixth sense when it came to Geometry. I could look at a formula and actually visualize what the object was in my head.
Even the trick items the teacher pulled on me a few times.
I remember saying, just because you can write down the equation, that doesn't mean you could physically make the item.
Think about the picture of several straight lines all equally spaced, but closed at the ends, on one end it shows four beams, but at the other end it shows three beams. You can write the equation, you can draw it on paper, but you can't make the physical object.

Like you, I too had an easy time with Geometry but only made it through Algebra due to the kindness of the teacher. He knew I tried hard but failed most of the tests. I got one grade above failing in that class which was enough for the diploma requirements. The plane geometry class was pictures that I understood, but all those geometric figures had formulas and theorems to prove they were valid. The entire semester was spent proving those theorems. Each student picked theorems from the text book and then had to write out the proof and draw the diagrams on the chalkboard in front of the whole class. While that put a lot of pressure on the students it was probably the best way to teach something like that. Some of those geometric objects could not be visualized, by me anyway. But, I at least had an idea what it was all about. The last high school math class I had to take was trigonometry. That was like a mix of algebra and geometry. I had trouble there with all the formulas but managed to get a fair grade. Those trig formulas referred to actual situations that could be put into a real world context, such as surveying. Algebra was all theory and way beyond my imagination.

The last time I looked into it getting a passing grade in your class was not enough to graduate. You had to actually attend a certain number of classes per semester in order to be given the credit. I believe we were allowed 5 or 10 days out, and more than that would be an automatic failure. You probably would have quit school altogether if you were forced to do that kind of school work. LOL

I didn't get into Trig until my Sophomore year of high school. But I learned enough in those classes that when it came to the learning Drafting and eventually getting my early career in drafting, I had learned enough I got put into fairly high level areas of the job right off the bat too! The only sad thing is drafting never paid a very high salary, no matter how high up in the department you were. It wasn't until I landed a job at MRTC that I was paid what I would say was a more than fair salary for the era.

I did go to classes on the day they had tests, but not all classes had a test, so I may have only been there for an hour or two.
My grades were high enough to graduate, and my attendance, after I came in a few extra days so the school got their government dollars, which was actually doing extra work around the school, not classes actually, just putting in a few hours here and there. I only had to have 6 more hours before graduation, so they had me putting number stickers on all the chairs both inside and outside for the graduation ceremony. My poor fingers were so sore from doing all of them. But I crossed the stage with everyone else and got my diploma.

What is truly ironic is I spent more time in school after I graduated than I did when I was supposed to be in school.
Plus I traveled to Tempe, Arizona to teach VOTEC for two semesters a couple of decades later. Needed to do that to get my general contractors license. So I figured, do it all at once and get it over with, rather a month a year for 5 years, hi hi.

A person's education depends on more than the mere attendance of classes and passing the tests. That's why some students attain a 4.0 GPA and others barely reach 2.5. I think that ability to learn is called IQ. The IQ number doesn't say how smart you are, but it does indicate your ability to learn. Usually people do what is easiest for them. If learning new things is easy, you do well in that pursuit. Your skills in absorbing knowledge show in the stories you tell which have nothing to do with classwork. The family business you mastered and all the vocations you pursued outside that is testimony to your high IQ. Your curiosity about how things work is probably the best example of your intelligence capabilities. I can only add one other observation by saying there seems to be two types of intelligence; theoretical and practical. You certainly proved to me that you excel in the latter version.

Why thank you Yogi!

My observation is similar. But also, I see a lot of people who are super smart, but only in one thing, what they were taught.
It seems the poorer folks who had to do everything for themselves have a much broader knowledge base than the college elite.
But that's OK, because the two more or less work hand in hand. You need someone to run the show, and others to be the performers.
The trouble today is, everyone wants to run the show, and nobody want's to be the performers.
Enter robotics to take the place of the performers, as mentioned in your other post.

I'm probably the only person you know, who when I got a flat, never changed a tire or called AAA to do it for me.
If I get a flat, I plug the tire and reinflate it. Never need to get out a jack and lug wrench, take off a tire and install a spare.
That don't mean I don't carry a spare, just in case I damage the sidewall and the tire is ruined.
Many long years ago, while driving up to Denver, Colorado, I had a major blowout.
By the time I could stop and pull off the highway, the tire was ripped to shreds.
That is probably the only time in my life I ever actually changed a tire while on the roadway.
I have rotated my tires myself many times, but that's not the same thing as an emergency repair on the side of the road.
Plugging a tire is much safer than working with a jacked up car with tractor-trailers flying past you!

You and I could plug a tire and use a lug wrench if we had to. My wife, however, could do no such thing. Does that reflect on her intelligence? In this case no because she simply does not have the physical strength in her hand to do the job even if she wanted to. Thus the AAA is a profit making organization. We don't have any such service, by the way. I'm the go-to service guy in most cases. LOL However, my wife of many years has traveled alone on more than one occasion in which case her Google Assistant on the phone would be the emergency helper. Fortunately we never had to test that out.

There are some very interesting people I've met who have that specialty in a single subject you speak of. One young lad in particular was a math whiz. He could solve most any problem requiring calculations (such as estimate how much pizza is eaten in the US in a given week) without the use of a calculator or computer. He did it all in his head. Did I mention he was autistic? He was one special person indeed. Another gal I knew could read a series of numbers once and recall them a month or a year later. I gave her what must have been a 12 digit serial number off my trash bin to memorize. About a year after that we met in person and she rattled it off as if it were her phone number. She claims that it's permanently etched into her brain and could recall it 20 years from now. Like me, however, she was terrible at math. The brain has some amazing capabilities to be sure.

Like so many other things, the ability to learn something comes in varying degrees. It's just the way the brain is wired. You are an expert at logic and organizing details which I believe is a left side of the brain function. The right side brain deep thinkers among us could hardly figure out how to use a pencil sharpener but will explain quantum physics easily. The reasons for such variance could be genetic based or the environment we were exposed to when growing up. But there are limits to what certain brains can do and those limits are what makes a person a specialist. It's not simply a matter of learning because some people can't learn what others find easy to do.

I had a brand new battery go dead on me in the worst part of downtown St. Louis.
So much for taking short cuts.
It just so happened that Debi had a free service company.
When I told them my make and model, and that the car won't keep running using my quick charger.
They came out in less than 15 minutes with a loaner battery, of which I had to return to ANY of their locations.
Thankfully, the location where I got my new battery was right next door to one of their service locations.
And I didn't even have to carry it over there, the guy who installed my new battery did so for me.
Needless to say, I gave him a big tip! Also, since my new battery is what went kaput, there was no charge for another new one, or the installation.

I used to have a power plug gun that anyone could use. It plugged into your cigarette lighter socket.
What I didn't like about it was it only made the hole bigger since the nozzle was like a hole saw.
But it did use the larger size mushroom top plugs, which are the best ones really, because it is like a patch inside the tire.

Oh wow! Yes, autistic folks are amazing at math, and I've also met a few folks with photographic memories. But not all of them have long term memories like the gal you knew. The fellow I met I though was most amazing was not an artist, but he could look at complex drawing containing many items, and you name the item, then he could point right to where it was looking only at a blank piece of paper or white board. Ask him to point out five or six things, and he would draw circles on the paper of where they are on the drawing. Some you couldn't even see yourself after studying the image for ten minutes, but he only glanced at the image for 30 seconds and knew where everything on it was. Amazing fellow.
Our family knew a friend of my dad's since he was around so often. He was stone deaf! But he could read lips really well.
After he smashed his hand at his place of employment and could no longer work, the FBI would call him to go on stakeouts with them from time to time, and he would tell them what the folks were talking about. They paid him really well too!

There were these two doctors who used to invite me over to their house, sometimes to their office, just to talk with me after I had another attack. They were trying to figure out how something I never knew very well, if at all, could suddenly land me a job in a field for which I had no training or experience. I had to tell them, it really didn't work that way, because I always had some early background in most of the things. Like electronics, I built many Heathkits over the years. But when it came to figuring out the problems with circuit boards, I don't really know how I knew how to do it, but after another attack, I had no idea at all.
But it was replaced with enough knowledge about chemistry, I was able to develop several things, and one of those was my AZ-NO3 product which is still on the market now after 25 years. Lucky for me I wrote the formula out in plan English using only ingredient names and the amounts of each one, and the order in which they had to be blended or cultured.
Sometimes I will read the pamphlet I wrote on how it works that went out to wholesale buyers and dealers. I can honestly say, I have no idea what any of it means anymore, but at the time I wrote it, I understood it perfectly enough to write it, and in such a way it did not disclose my actual formula, hi hi.

I don't know if we will ever figure out how the brain works. It would be like a microbe looking at itself through a microscope to try and figure it all out. There are things definitely associated with brain functions and which cannot currently be explained. ESP is one example. It's a demonstrable phenomena which is so unfamiliar that most people don't believe it works.

Another interesting phenomena I learned about has to do with memory working in reverse. This is actually a very sad story and I can't get into a lot detail here, but I knew a person who was physically abused constantly as a child. Some sexual abuse was involved and the child managed to get into their teenage years before it became a visible problem. As often happens, particularly with teens, extreme trauma can develop into suicidal behavior. The problem was that the parents were involved with creating the trauma. Thus the people responsible for the child's health were the root cause of the problems. It got to be pretty bad by the time I met this person and we had some long talks about the abuse. I could do nothing but listen. Several suicide attempts were made but since they were not successful the father of this child downplayed it all as them just being a rebellious kid. Then one time the kid ended up in ER and nearly didn't survive. Now the medical community was aware of what was going on and something had to be done.

There are several treatments for depression and suicidal behavior, none of which seemed to have much affect. The final treatment was considered to be a last resort because nobody knew for sure how it worked. The doctors decided Electroconvulsive therapy (ECT) was appropriate. You probably heard of it as shock treatments. The procedure is nothing less than inhumane, but it is done under anesthesia. The result, hopefully, is to erase memories of the trauma affecting a person's behavior. Everything else in their life is easily recalled. It took about a year for the full effects to manifest, but this person became fairly normal because they could not recall the abusive behavior experienced earlier in their life. Incidents before and after a specific event can be recalled, but the event itself is erased. While this is a good thing in that it brought this person back to a near normal life, I am amazed onto this very day. How is such a thing possible? I've read a bit about it and there are some theories, but nobody knows for sure how selective memory loss is brought about through ECT.

Based on a study I was remotely involved in back in my college days, but not at the colleges I attended, even though it was talked about quite often.
A college built a small room lined with lead, then built another room around it, also lined with lead, and another room around that lined with lead. I don't remember now if it was four rooms deep or only three.
What they were trying to prove was that our memory is not in our own head, but that our head was only a transmitter/receiver and what we remember is transmitted on our specific frequency and then recalled.

How it worked. A person would go into the innermost room and read a short book. Then go through the door to the next room and write a book report. Then go through the next door and write another book report, and through the next door and write another.
By the time they were back outside, some of them did not even remember reading the book.
While others still recalled the entire book and all their book reports matched the first to the last.
What they determined from this was our memory transmission possibly only circles our own head on some people, but circles the globe on other people.
And the reason we remember something from years ago, is that each time we think of it, it gets retransmitted, so the signal is fresh each time.

Now, taking those who could still write the book report perfectly after they were out of the rooms, for those folks they figured their transmission traversed the globe, not just spun around their own head.
And it was those they chose to see if they could tune into other peoples frequencies, to prove ESP was possible.

Their only success at that time was between mothers and daughters, and even then it was vague. So could not be substantiated enough to say their experiment was a success, but they didn't consider it a failure either, since they did learn there are possible two or more types of ways we remember things. Either locally or globally or both as is the case with a traumatic event that is transmitted at such high power, one does not forget it, even though they may not recall it as often, or even try to forget it.

I went to grade school with a severely abused child. Fortunately the problem was caught and both parents ended up in prison, so they must have been really bad dudes. And I think the child was placed in the Lutheran Orphans Home, but still finished out the school year with us.

I never understood much about shock treatments, or even those frontal lobotomies either.
I only knew one distant aunt who is said to have had a lobotomy when she was younger, but that's about all I ever heard about it.
Parents didn't talk about those kinds of things in front of children.

Your story about memory is a first for me. Most everything I've read is based on the brain organ containing the memory capability. That's not to say thoughts cannot be transmitted, but every neurologist I ever read assumes the storage is local. I suppose that would be equivalent to a hard drive inside a computer which also has WiFi capability. Memory recall is not precise. You miss a lot of details from the actual event when you recall it later on. The recalled memory is then stored again but this time with a lot of the detail missing. Thus, over time, we forget things. That is why it's necessary for you to keep doing rote tasks to keep their memory fresh. Apparently after you recall them they do not get stored again in their original form. Some folks lose more detail than others, and I'm guessing you are close to a worst case scenario. The concept of "cloud" storage is interesting and suggests there is a higher level consciousness of which we are all a part. That could be, but nobody has proven that connection yet.

The old saying of "Use it or Lose it" is very apropos, whether the storage is in our head, or floating around our head, hi hi.
I do think a LOT of what we know, things we use every day, is stored in the old gray matter for instant recall, like an SSD.

Not to change topics, but sorta along the same line. I also believe there is an aura around us and some animals can see this aura.
For example. The arthritis in my left elbow is really painful at times, so are my hands as far as that goes.
My little pooch, when he is around me in such a way he can get to my elbow, even if he is on my right side, will move over to the left in order to lick my left elbow. Sometimes he will lick the knuckles on my thumbs, when they are super painful.
He rarely gives me licks anywhere else, and this only seems to happen when the pain level is the highest in my elbow. So it is not like a matter of habit.
We also have a couple of dogs who steer clear of each other, and the older one is losing their vision.
On days when the dog who is losing their vision has really bad days, the pooch that normally stays away from her, will go up and start licking her eyes, trying to help, and she will sit there and let him, without running off as usual.

Now back to the gray matter.
How our brain stores things must be amazing, because we know it only saves some things, and then assembles them later to form an image.
I've been in a few tests where they would flash a picture up on the wall, usually black and white with some darker lines and lighter lines. The odd thing is, the entire image is there, but our minds don't see it.
For example: The picture will flash on the screen, and your mind will assemble it to be a chair, but then when the image is left up for you to look at it for a longer period of time, you could see it wasn't a chair at all, but perhaps a tractor with a silo in the background.
And I'm sure you've seen those memes with words spelled wrong or using numbers in with letters, etc.
As long as the first letter and last letter is in the right place, you can read the paragraph with little to no difficulty.
But that is the key to the trick, having the first and last letter done properly in the right place.

So, our minds are amazing things for sure. Even so, I think our brain itself is more like RAM, and what is in it, if not refreshed often, scrolls of the end of the queue, hi hi. While traumatic events you can recall for years after the event. You see something years later that reminds you of it, and you can recall it. It is these types of things I think are stored in our cloud, not inside our headbone.

Regarding human auras, I can concur with your conclusions. I've mentioned more than a few times my interest in paranormal events. Human auras have come to my attention through reading and in interviews with people who claim they can see them. The people I've talked to were adept at diagnosing illnesses using what they see in the aura. Emotions too apparently are broadcast very clearly, and that gets pretty interesting when it comes to determining if somebody is telling the truth or fabricating an alternate reality. Some people report seeing very dim and highly transparent auras while others say it's brilliant and clear. I've seen courses that teach how to view auras, but I never signed up for one. Most people say you can either do it or not. It's not something learned. One gal I met said she saw them since early childhood and never knew it was odd until later in her life she learned that most people don't see them. I don't recall specifically reading about animals being able to see auras, but I have read where they too are surrounded by this strange halo of light. I'd not doubt that animals can see auras, and other things too. My pooch barks at something invisible once in a while. Then, too, she may must be hallucinating.

Memory is not fully understood but there is a lot of information about how it's done. There are nerve synapses that allow communication (via chemical exchange) from one nerve cell to another. This is kind of a binary arrangement wherein a nerve is activated or not. An aggregation of cells takes on a function and thus this function becomes etched into the gray matter. For example, the brain knows via sensory inputs that something is hot. That's a function stashed away for future reference. Another part of the brain processes color. Thus, when you stick your finger into an orange flame that is hot and also experience pain, the brain triggers a reflex action that yanks your finger away from the source of pain. Going forward in time, when you see this same combination elsewhere in your environment, you avoid it because you remember from past experience that it's not a good thing. Other details about your experience with hotness, flames, and pain may not be harmful, such as when you were involved with glassblowing. The brain figured out that it's OK to blow some air down that tube because not all the criteria for danger were present. No pain when your lips touched the tube, for example. So, it seems, that memory is composed of several functions that are related. Your senses tell the brain what is happening, but the combination of factors from past experiences is what causes a memory and a subsequent reaction.

Clear as mud, eh? Well, it makes sense to me. :lol:

I had the opportunity to use Kirlian Photography at one of the colleges up in Canada.
It's not actually photography in the sense of taking a picture, but does use photographic film and an electromagnetic plate.
We used it with leaves from a few trees.
If you cut a leaf in half, and quickly place it on the film on top of the plate, the final image will still show a whole leaf, even though half of it was missing.

There is also aura photography, but it uses specialized equipment and uses the electric from our bodies I think.
I've never seen it done or been around anyone who has ever done it, but I do know it exists.
But apparently not well enough to end up being used in the medical professions yet.

You latter part about the brain makes sense to me.
Albeit I view how our nervous system and senses work, perhaps a little bit differently than you.
I see all of our senses as being broken down into various frequencies.
Touch for example would be a very low frequency signal, while eyesight would be a very high frequency signal.
Taste and smell would fall somewhere between those.
Our reaction to those frequencies is of course controlled by what our own brain learned about them.
All interesting stuff for sure!

My LED light began flickering faster and faster until now it is almost not perceptible, however, about once every three seconds it will go off and on about 15 cycles, but the off time is very short, then it will speed back up again to faster than the eye can perceive the flickering. I know the problem is because they use switching power supply circuits instead of energy eating analog circuits.
When LEDs become more commonplace, I don't doubt our light fixtures will be wired using Low Voltage like 12 to 48 volts, so no power supplies will be needed for the lighting.

Now that you bring it up I have seen photographs of auras. I recall the image but not any of the story behind it. If it were just a matter of light then there would be no problem constructing a special camera to photograph said auras. After all they have images of invisible energies floating about the universe so why can't an aura be photographed?

As far as your view of perception goes I'd say the differences between you and I are that you see it as an analog phenomena and I lean toward the digital explanation. There are indeed brainwaves that can be measured. However, sensory inputs are essential chemical reactions among nerve cells. They terminate in the brain organ and I don't see why the media would change at the root. Regardless, it's all very interesting to think about.

I think low voltage AC was ruled out due to line losses. If you drop a few volts off 120 not much difference would be noted. Do the same at 48 volts and it could be a significant degradation in performance. I could see a DC source being added to the AC input lines. That DC would be generated locally and used for such things as lighting which, in turn, would simplify the design of the light bulbs. But is it worth it? Apparently not at the moment.

I wish I could find that study of the college kids who were in the lead lined rooms again. It was an interesting read, even though it didn't prove what they hoped it would, it did shed light on a few other things of interest they were going to pursue, but I never saw anything else after that article.

I do know the synapses in my head get scrambled when I have an attack, but not both side of my head, only one side.
The doctors call it "Sub-clinical Epileptic Discharge affecting the right lobe." But don't have any idea of what to do about it.

I've worked in several subdivisions that had low voltage 24 volt wiring to all the switches in the house. Didn't matter if they went to a light fixture or a power outlet. All the on/off switches used the 24 volt system.
Inside the furnace room was a large panel that held the 120 volt AC wiring, along with relays activated by a 24 volt coil.
I imagine at the time this system was used, it had nothing at all to do with safety, and a lot to do with the cost of wiring at the time. Companies could use non-licensed employee's to run the low voltage wiring from the panel to the switches, using cheap bell wire. The electrician only had to tie in the outlet and lighting fixtures to the panel box and his job was done.
I did save my customers with this system a lot of money by not buying the whole relay module when one went bad. Most of them it was just the coil that went bad, and they could be purchased fairly cheaply. A few times it was the contacts that wore out from being triggered off and on so often, but contacts were super cheap. A box of a dozen for like 2 bucks, hi hi. Coils were only like 4 or 5 bucks, but the whole assembled module was closer to 45 or 50 bucks.

FWIW: There is more line loss in DC circuits than in AC circuits. This is why the country is AC instead of DC. Edison actually started out wiring cities with DC if they were close to the power station. But it couldn't be brought very far, which is why AC took over so fast.

From what I can gather the nerve synapses act something like CMOS memory used on those USB sticks. When you write to them the transistors maintain their state and in aggregate form a memory cell with useful information. That only works a certain number of times. Once the expiration date comes due the memory is stuck in one particular state and can't be reset. The only way around that is ... backups. There are a lot of spare neurons in the brain and I suspect some of them are in fact backup, or augmentations. Unfortunately, I could not tell you how to backup the information in your right lobe even if I wanted to. It will be possible some day, but at the moment it's no available to anyone but a few research scientists in a lab somewhere in Transylvania.

Yes, DC has a lot of loss over great distances, and I am aware of how Edison started out. I've had doorbells and furnace thermostats running off DC and it might have all been 24 volts. There is hardly any duty cycle for those type of devices and the line losses would be insignificant. Light bulbs, however, would be on for a long time, but even so it's hard to see a lot heat dissipation due to line loss in a house run on DC light bulbs. The point of installing a DC supply would be to make the cost of light bulbs cheaper. That's the part I'm not certain would be worth the effort.

And LED is a Diode, the job of a normal Diode is to convert AC electric into pulsing DC output.
Most LED lamps are only 3 to 5 volts.
You can replace the Diodes in a square wave bridge rectifier with LEDs thus give the ability to use a 12 volt AC power source to 12 volt DC output.
A single LED on an AC circuit would flicker at the cycle rate of the AC power, in the U.S. this is 60 times a second.
To stop the flicker, you use a pair of regular diodes, a resistor, and in some cases an inductor ahead of the LED to get a non-flashing LED light output.
You can wire 24 five volt LEDs in parallel on a 120 volt AC line without using resistors or diodes and they will not flash.
They actually do, but at over 1,000 times per second, so it is not perceived by our eyes.
It also has to do with the rise to peak and fall back times of the device itself also.

The thing with DC is, the farther the run, the larger the wires must be to carry the load.
Although the load does have a bearing on AC as well, it is much less, so smaller wires can be used, and over much greater distances. But the real benefit of AC is the fact you can carry super high voltages on small wires, then use step-down transformers to get back to household voltage. Can't do that with DC at all.

These LED lamps we buy that screw into 120 volt light sockets, are actually using a lot more electric than the LED itself uses.
The only saving grace right now is the fact they use switching power supplies. If they used analog power supplies, we would not see much of a savings on our electric bill.
Most folks never gave much thought to how much power was consumed by those little wall warts they left plugged in all the time.
In the case of the analog type of wall wart, they used the same amount of electric whether you were using the output from them or not. Same with a rapid start fluorescent lamp that used auto-start ballasts. They use the same amount of power if the bulb is burning or if it is burned out.
Switching power supplies use a small amount of electric for the initial energizing coil, but no real power until you apply a load, then the switching feature kicks in and only uses current while it is charging or running something.

All I can add to clarify what you described is that diodes conduct electric current in one direction only. That is why you get a pulsed output when you apply an A/C source. There are various methods employed to filter that output to be clean DC. The most common one I've seen is the addition of a capacitor and possibly a resistor. The more capacitance you add the cleaner the output. Some situations do not need clean DC which is pretty much what you are saying about lighting. The fans on my computer motherboard are Pulse Width Modulated to control their speed. Switching power supplies operate at a higher frequency than the normal A/C line which make them easier to filter and is why they are favored. Fewer parts means cheaper.
