But remember, people tend to live in communities, chunks of communities. What does this mean? It means that the theoretical average of IQ (100) can be or in most cases is irrelevant or meaningless 😉
For example, in your house, what is the average? In your schools, what is the average? In your office, what is the average? It is then easy to understand the relevancy.
It's interesting how some really smart and talented people can be quite childish and frivolous in the more normal aspects of life like having relationships, taking care of personal health, managing money.
Ah! Gf versus Gc...
I didn't know this. I mean if it peaks around that age. But that seems to be true. But it is hard to measure (or to "feel" it) because Gf and Gc develops at the same time. Gc peaks at much higher age. And IQ test cannot only measure Gf, it always measure both.
I feel that, in my older age, I have developed a certain level of Gc. May be there was a plateau at certain period, where Gf stops developing and Gc is not yet developing. At this plateau, people may feel worry why they cannot do what they used to be able to do easily 😉
Intelligence is not the same as wisdom.
Also, 95% of what brains do is outside of, and unobservable by, conscious awareness (which is the little 5% part). Part of what distinguishes smart people from others is the ability to think up long lists of all the reasons why they are right, even when they are wrong. Because they are so good at justifying what they want to believe, it can be more difficult for them to realize when they are wrong.
Again, I would refer anyone to the book, Thinking Fast and Slow, for a lot of info on how and why people make mental mistakes. Most of the mistakes arise from processes running in the 95% of brain functions that they cannot observe or otherwise have direct awareness of. The default is that conscious awareness tends to endorse and believe whatever the 95% comes up with.

That is the name for long pillows in the Far East; the Indonesians have their bantal poloh, an so have the Japanese where I think this expression originated. My guess is that it comes from the time when the Dutch had quite a number of outposts in the Far East, often manned by lonely guys, who comforted themselves by holding on to these long pillows.
Anyways, anybody who has had anything to do with Dutch women knows that they are as real as it gets. Not that plastic of pillowy at all.
You were lucky. In second grade, 13 years old, my math teacher put me in a corner with the 4 color problem and the challenge to prove that a circle segment cannot be divided in three with compass and ruler and other such useless riddles. I was only welcome in physics lessons for experiments and exams during most of college. By the time I started to study physics at uni, I was completely bored by the topic. Was it Russell who remarked that the entrance to the world of mathematics is a small door you have to cross while young because otherwise you will no longer fit through it?
There was an article I read a year or two back, where they stated, like for like, the average IQ had risen by 10 points over the last century.
Since 'average' is deemed to be 100 it seems to me its quite plausible that longitudinally, IQ's will rise over time - the average at any one time always being pegged at 100.

If I was lucky, I think it was probably at an earlier age, about 13, like you. My parents would take me to the library. I found books on building radios, and saved my allowance to buy parts to build my own.
At about the same age, I also had a teacher not too unlike yours. One day she gave the class an assignment to write an essay in class while she graded papers. I was bored and read a novel instead. She caught me, confiscated my book, and my parents were called down to meet with my counselor. (The book was Catcher in the Rye, and the school thought I was too young to read something like that.) It was decided for me that I would write the essay and turn in to the teacher. I did. It was a scathing critique of the teacher for wasting my time in the classroom by assigning busy work, so she could spend the time doing something other than the teaching she was supposed to be doing. I got an "A."

It has been said that IQ may now be declining. One suggested reason: In the modern world, people can survive long enough to produce children even if they might not have been fit enough to survive in a more primitive and harsh world.

Many disciplines require continuous study from the most basic level to the most advanced level. Often there are pre-requisites for every level, which means we cannot move forward before we master certain more basic skills...
In a school system where there is imposed time frame to study such discipline, once you get left behind, you have to work out by yourself (if only you knew that this is serious; if only you knew how to work "alone"; which is very unlikely) because the school system just don't care (or also don't know the problem).
With Math, I believe that the real bottleneck is in the very basic elementary level of Math, not in the rather advanced ones.
Unlike Physics, Math talks about imaginary concepts. It is hard to find a Math teacher that can make complex things simple. But that's fine. Math is not that important in life 😀
Many Math teachers come from pure Math/Science major. They don't know how to implement the Math in real life. Different with us engineers, many of us have to develop Mathematical model and solve it to solve an engineering problem. But not many that has the chance to reach this level either...
Time for you to visit a museum, there are a few around the globe that exhibit examples of 1st aid kits for mariners.
(I recall I wrote an essay on the sexual obsession with women of men for Dutch classes. My hormone level at the time may have done most of the hard labor, but I've not scored a higher grade before and after. Good thing the teach was an erotic literature obsessed bloke)

Thank you Mark.
I agree.
Like with any other professional who “doesn’t know” how to do his/her job, I think they simply don’t care.
It is one thing to be a qualified mathematician, it is another thing to be a teacher who cares (they exist though).
Not in warm and humid climates 😀

Efforts to make the world idiot proof negated by the production of better idiots 😕
Dang, all these years I've been thinking I was having it on with a 40'' bloke, while my g/f was vast asleep on the other side of the bed.
(posted it before, stuff like dimensional analysis should be taught at a much earlier age, to all kids)

Average IQ has risen due to better prenatal medical care, fewer retarded are born due to avoidable issues, such as malnutrition, alcohol etc.
As to a decrease due to differential birth rates, that is often cited in eugenic arguments.
As to intelligence, one fellow I know while getting his undergraduate degree was teaching graduate courses at the University next door. Last time I visited him, there was an oriental rug on the floor, quite dirty and chewed a bit by his dogs. It was given to him by an older family member. I mentioned that the rug was worth at least US$10,000 in good condition. He didn't believe me.
As to math problems attached is a picture of my latest project. A well used device that is intended to hold up a small tablet computer over the mixing console. Easy to build, but I suspect the standard approach of the spring counter balance is wrong. For anyone willing to try the problem the arms are .5" x .5" x 23" and weigh .4 ounces per inch. The spacing is 2.5" and the spring point is 6.5". The counterbalance is not consistent through the range of motion. I suspect that two more sets of springs at a different pivot point will assist linearization.
For mechanically unaware the the holes are .25" and the edge of a hole is the same as the diameter from the edge, except for the spring holes. That gives close point pivot spacing of 1' for clearance.
