Univesp check 😂😂
goated
who won?
Sog!!
It mystifies me why they feel impelled to add utterly pointless music to information videos. Irritating and distracting.
note: number of bounces - entropy is maximum when all outcomes are equally likely . when introduce predictability the entropy must go down. thanks for sharing this video! God bless you!🎉
Thank you so much. It explains the entropy so well.
trippy edit love it
WOW! This is great, that was so simple and concise.
this is super education
Univesp aqui 😉
Wow, What a so concise and clear explanation. Thank you.
Muito Bom

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.
