    Hope you folks enjoy my version of a "test"! (The text version is linked in the description). There's a text version of the test linked in the description. Don't comment any "answers" unless you leave a mark it as a spoiler and leave a ton of space so people would need to click "read more" to see it (sorry but I will remove comments that have answers showing)

    I really liked the 'appreciation' section. I thought that was cool. It is easy to hyper focus on the parts of life that suck. So, anyway, it is good to be reminded of things we can be grateful for like plants, animals, nature in general and the parts of our life that are going well etc. Thanks for the test.

    As a computer programmer and not a mathematician, these questions would be great practice tools for learning a functional language like Haskell. Crafting an equation in your head and than turning it into code. Its similar to the great Donald Knuth's example questions.

    When I was in Uni, my favorite tests came from algebra and number theory classes. In these tests (at least where I went) there was always at least one problem that made us write a proof for something that we've likely never seen before. Also, these test were almost always open book tests, so there wasn't much required memorization. Instead the proof writing would force you into thinking about new concepts and how you can use logical tools to prove a thing without a doubt. (these tool were what you would look in your notes for, a simple early level example is 'proof by induction' - powerful tool though, even though its taught early.)
    I can remember the first time I ever saw a double factorial, it was introduced to me during a pretty important test on a problem I had to write a proof for - literally had an explanation of what a double factorial is at the start of the question, lol. This sort of "new stuff you've never heard of before suddenly being on a test" happened all the time in these classes and I think this is great way to get a measure of someone's ability to apply logic quickly to a new situation.
    Finally, besides the final exams, most the grades came from assignments AND they would drop the lowest graded test, so even if you struggled in a test environment, that wouldn't completely screw up your grades up

    Great take on testing. I enjoyed trying to answer at the questions while watching (I haven't seen all class videos so several of them I'd have to do more research to answer them).
    But honestly I think school systems could take a big lesson out of your testing ways, especially on the opinion part as that can be a nice way of testing theory without pure memorization; saying theory here because more practical tests have an easier time at testing outside-the-box thinking. Don't think the appreciation part is very applicable to a school environment though, but it's still a cool idea nonetheless.

    • @grodifer4644
      @grodifer4644 Рік тому

      I think that school should be a place of learning
      and sometimes we can get so sucked into looking at the negative that we forget how to look at the positive (not that the negative doesnt exist, but sometimes we get to the point that we lose our ability to see the good in the world)
      I think schools should have little reminders, be that in homework or tests, that make you (re)learn how to appreciate the things around you and what the people that came before you have done to make that life a little better
      (potential double whammy of history and positivity, assuming it works ofc)
      testing needs a massive overhaul anyways
      so maybe finding a way to fit some appreciation into them could make tests a more effective tool for gauging understanding
      idk
      however, i do know that i generally do better when im in a positive mental state
      but also im just some dumbass on the internet
      so who knows

  • @livedandletdie

    I mean, this is a good test, that all relates back to your videos, and as such is actually a good test, to see how much people did remember of the videos, and even if some of the things are harder than others, it's a good measure to see how much random mathematical nonsense and other stuff you could successfully cram into your head. And still some parts about thinking for yourself, which is seriously what tests should all be about, to test yourself, not to be tested by others.
    As a former runner, got disabled 19 years ago, had to quit running, but as a former runner I understand the concept of testing oneself, which is seriously the best thing you can do, if you really want to learn stuff.. In language learning it's called Revising your knowledge of the language, more often of it's vocabulary than not.
    It's like understanding the Quadratic equation, ax²+bx+c=0 and it's counterpart for solving it the Quadratic formula, or the other formula the PQ formula.
    ax²+bx+c=0, x²+(b/a)x+(c/a)=0, x²+(b/a)x=-(c/a), x² + (b/a)x + (b/2a)²= -(c/a) + (b/2a)² , (x + b/2a)^2 = -(c/a) + (b²/4a²) = ((b²-4ac)/4a²) , x + (b/2a) = ±sqrt(b²+4ac)/2a , x= -(b/2a)±(sqrt(b²-4ac)/2a) , x= (-b±sqrt(b²-4ac))/2a
    For those who didn't know the step solution to the Quadratic formula.

    Underappreciated number: Ten.
    Specifically, base Ten. While base Twelve is easier to do simple math with, I think that having a base that's just a little peculiar helps us to understand other bases and numbers better, because we get less locked into thinking that the way we do things is right. For example, I think we understand the number 7 better by using base 10 than we would if we used base 12 because of 1/7's pattern of remainders. It's not hard to know when something is divisible by 3, anyway.

    My experience with tests in school is they are no longer the "learning tool" they once were. In the 1960's and 70's, you received your test paper back after it was graded. The answers you got wrong were marked. In the better classes, you could ask why your answer was wrong. These days, tests are not handed back - all you know is what percentage you got right, with no clue as to which you got right or which you got wrong.

    i agree that an iq test is not a direct measure of intelligence but rather aptitude. the only thing i didn't agree with, was your statement that all they test is visual pattern recognition. there's reaction time, coordination, short and long term memory, math, and speech related assessments. a real iq test takes upwards of 6-7 hours total to complete under the direction of a psychologist. there's also a lot more results that come from it beyond the iq itself. but yeah besides my paragraph this has been a great video thank you mr. domotro

    @JuliusUnique Рік тому

    Here are my somewhat short and some wrong answers/guesses.
    so if you don't want to get spoilered, don't continue reading this comment, some answers might be right
    1.I had 9,10,12,8,11 chatGPT said 11,3,9 and 123*11modulo12 but also 123modulo12
    2. I would have guessed 2-3 since it's kind of the average difference, but after being in combo class I think it's 1 because the odds of getting that difference is 10/36, 1-2;2-3;3-4;4-5;5-6, so 5*2 because it can also be the other way around. while for 2 or 3 there are only 1-3,2-4,3-5,4-6 (8/36) and 1-4,2-5, 3-6(6/36)
    3. Fire has 4, earth has 6, air has 8, aether has 12 and water has 20 and nothing has 0, I added nothing so we have 6 numbers, to show that the universe wants us to use base 6 xD
    4. there are like 45 even numbers and 30 threeven, and every 3rd threeven number lands on an even number so I'd say the answer is 90-(45+20)=25
    5. 3,6,9,12,15,18 seems like 50% to me, almost said 2/3 because of 4. xD
    6. the biggest prime number currently know is very big, and I'd say half of the digits will be 0 but to get more digits in binary you need exponentially higher numbers, so my answer is:
    not that many but still a lot (Im ok getting 0 points here haha)
    7. b. c. I choose 288 since it's 2*12^2 and way below 12^4 so not divisible by 12^4 or am I wrong? and 288 is 12*24 and since 10*20 has two 0s I guess 2 as well, how bad is it that I cannot tell this intuitively? probably very bad but ok
    8. I admit I saw the video but skipped thorugh it and don't remember how to do it with negative bases
    9. A. 51 B. 31 C. not real enough for me xD
    10. I did it from 1-17 and my inductive conclusion guess is: 4,0,7,5 and 2
    11. first guess was 111, didnt work, second guess 101 did
    12. if I understand this question right, I would "a lot", because using very big prime numbers makes a very big numbers with a lot of factors, if I have tosay which of the 5 used then all 5 because negative numbers aren't prime numbers
    13. 5/3
    14. 27-16=11
    15. 2*2*1*2*3*1*1*1*1...
    16. smallest number? isn't it like 2^2*3^1*5^1*7^1? which is 420
    17. does mod 18 mean between 0-18? not sure what "congruent to" means outside of shapes
    18. if I imagine the circle of unity and the x-axis as the real number line it would be 1 and -1 but tbh I have not much learned about imaginary numbers because I like it REAL lol
    19. A.11111 B.
    20. A. 4 B. 10 C. 4 D. square root of 2 even though I have to admint I do not fully understand the definition of algebraic numbers yet
    21. are there infinitely many prime numbers? since you said there is a biggest one, so seems like we didnt have a formular for infinitely many yet.
    it kind of bothers me that I watched like 3 videos about those million-price math problems and forgot all of them "entropy is not on your side - Elon Musk", I remember something about P vs NP and if it's P=NP or not
    22. pros: it does its job and is regulary, cons: the regularity might give the illusion that the future happened before, even it never did "oh it's another monday again, but the weekend will be great, like most weekends", to how we cut calenders: we could do it much cleaner, you made a video about it, also someone needs to change 12:00am/pm to 00:00am/pm pls. I also tought about haivng the months start with day 0 idk if that's better though, most importantly it should be consistent
    23. 6 because it's not our base system yet but is cleaner, it would also mean it's easier to the the silver and gold YT-trophy-thing haha
    24. time is cleaner, everything is cleaner
    25. the word "doch" is completely missing, it means "the opposite of what you just said is true." like for example I say "gras is not green" in the german language it only is used if someone claims a negative, like "this is not true" and then I say "doch, it's true" which means "yes, it is true!". We use "doch" a lot, it's not a rare word, yet comlpetely missing in the english language. (also the ch-sound could be somehow implemented in the english language which would be funny)
    I have to give credit to the english language though: it's smaller and therefore way easier. german grammar has a lot of complicated grammar. But the upside of communicating more precicely is very small, since it is a very minor usable information increase while it is way more to learn and also use. Also our 3 gender "der, die das" thing doesn't even work properly, we say "das girl" das=object, so a girl in the german language is an object, a tree is male a lamp is female and if you have more of anything suddenly everything turns female, it's very annoying as a logical person, hence I swapped to english, glad it's kind of the world language now
    26. well first of all I have to mention, in germany they forced: religion, german, french and some useless parts of history on me. Also "physics, chemics and biology" counts as a less important subject which is insane to me since those are the most important ones. I try to change it but the responsible people for what is taught don't listen to me, also they could teach the base 6 system in math since I never knew how clean it is, I already knew 12 is better than 10 but 6 seems even better.
    this is "what", when it comes to "how" I would say, more practically, more individually I guess, so everyone understand why he/she is learning a certain topic
    29. I do that a lot, I try to understand all technologies and how they work, I sometimes feel like I don't deserve a technology if I don't understand how it works. I remember how Einstein (yes, that guy again) once said in german:
    "Those people should be ashamed who thoughtlessly use the wonders of science and technology and who have no more intellectual grasp of them than the cow of the botany of the plants, which she eats with pleasure.."
