When a movie that released in 2012 got more love and better animation than a movie that released in 2024:
3:51 Typo when computing the entropy for machine 2
The worst explanation that i ever saw/heard
Are just want to make nonesense videos and upload it or want students to learn what you mean............ I am completely sure even you don't understand what you are saying...... You think of yourself as a professor while you are not .. 😑
The pseudocode I’m failing to understand, so from 2 till sqrt of n if a is unmarked then a is prime, 2 will be unmarked, which makes it price, now for all multiples of 2, 4-6-8 etc are marked as composite, then 3 and starting from 9 to n, so at what point do we check for example 79 if we are only checking from 2 until sqrt(n), if we picked n=100 then we’d only check until 10, so what about all the number after 10 that are not marked as composite, and nowhere does it say we are checking them
I think the math at 3:52 is wrong.. should be 0.25 x 2 instead of 0.25 x 4 but the result is right 1.75
I thought that they would demonstrate a Halbach array. They did not.
damn that was too easy this way. I've been studying this for the past 20-30 minutes without any clue.
Great What A Way😂😂😂😂😂😂
increase the strength NOT THE GRIP!!! IDIOTS!!!
5:55 ChatGPT?
I remember having a playdate with his son when I was a toddler, he was a quiet kid.
In 3.50 you mistakenly have written 0.25*4 instead of 0.25*2.
So from what I understand by using the 3 middle numbers after doing 2 /3 actions and repeating we are saving ourselves some time to find matching sequence. While multiplying these gets you around 10000 unites of numbers which is not as big as million it some how saves time and I suppose makes the probability of matching the numbers fairly moderated.
My bro is obbsessed w/ khan academy kids-
I feel like the whole Marlin flashback was moved to "up"
I was agreee 1000%
what a good and simple explanation, thanks
D.Angela is the reason
What if machine 1 had 6 letters ABCDEF? How many questions on average would you have to ask? Using the Bounce analogy I get 16/6 = 2.6667. But -Log2(1/6) =2.585. What am I doing wrong? Is it ABC? If yes then Is it A or B? If yes then Is it A? for A 3 questions. 3 questions for B. . But if it's C only 2 questions : Is it ABC, Y. Is it AB, N, then it's C. Likewise if it is D or E or F? "3 Questions for D & E. Is it ABC? No. Is it D or E? Yes Is it D? 2 questions if it's F. 3+3+2 + 3+3+2 = 16. 16/6=2.6667 on average not 2.585 =log2 (1/6).
Angela Yu brought me here.
There is a mistake in the first example. If the answer to the question 'is it AB" is no, why would you then ask "Is it B". It cannot be B.
I'm scared.
This is retarded.
Kudos for linking number of bounces -> binary tree -> log. And overall very nice explanation. That's like 3rd explanation for info entropy i liked.
This series of videos, with its breadth of knowledge, its ability to connect seemingly unrelated worlds, the clarity of its explanations, and its visual and auditory beauty, reminds me of the masterpiece "Cosmos" by Carl Sagan and Ann Druyan. Many thanks to the talented creators for crafting such a masterpiece.
One of a contactee aliens told him that their ship use reverse electromagnetism 🤔
I love ❤
Concise and to the very point!
Very nice exposition. I did, though, get a chuckle from the bike-lock analogy. As thousands of cyclists know by now, a lock such as the one shown is not safe even for eight seconds, let alone eight hours. (Hint: chain cutter.)
:’0 this looks extremely hard idk if I wanna learn 3d animation anymore

this rule doesn't seem fundamental to me
talent cannot be taught. We need originality. modern creative arts are fucked because too many people think they can be the next ...
show us one more time how it wont pick up the bucket...I blinked I must have missed it...
ok but what if i can only relay my messages through eve and there's no way for me to verify that who im talking to is actually bob (assuming im alice) then what? because that's basically me sending msgs through my isp and the isp doing a dh key exchange with me as well as bob so now my isp and the gov can easily eavesdrop on my msgs
Stunning explanation
I think he’s asking 💀
Amazing video! Really helped me to understand random number generators. Got reference from Angela Yu’s course on udemy
Thanks a lot for this deep concept.
It seems for me that these numbers are the fingerprint of God.
Its as clear as mud now , thanx 😂

what did i have to do to get this stuff recommended..... im seriously considering switching platforms now, i just wanted to find out what the exact process is of magnets becoming demagnetized after hitting them..... all i got was recommendations for "one man one jar" (why is that even on youtube now???) some horrific gore videos and kids shows....
