3blue1brownHow many questions you need to solve this problem?
NOTE BASED ON THE COMMENTS: This video is part of a series of videos. I uploaded all the videos in the series before the deadline. The follow up video is the one in the card at the end of this one. The reason for breaking up the full exposition in several parts is that I wanted to give time for people to think about this problem before revealing an answer. If you keep going down the rabbit hole of videos, you might get to some pretty outstanding mathematical technique!
In this video, we explore a classic puzzle with a twist: Alice picks a secret number between 0 and 15, and Bob’s mission is to figure it out by asking yes or no questions. Sounds simple, right? But there's a catch—Alice is allowed to lie once!
This video isn’t just about finding the solution—it’s about challenging yourself to think differently. Join us as we delve into this intriguing game of logic, deception, and strategy. Can you come up with a better approach than Bob? Share your thoughts in the comments, and stick around for the next video, where we push the boundaries even further. Keep your mind sharp and stay mathy!

The video starts with a simple problem and explores it in more depth. I really like this idea and I love the fact that the viewers are invited to think about some generalizations of the problem themselves. However, I'll love to see a longer video in the same spirit.

The style used is interesting but a criticism I have is that some times the screen feels too cluttered with text

The idea is simple and accessible and also very interesting. I like that it gives the viewer the opportunity to think about the problem. I wish it went into more detail about the solution. But overall I enjoyed it.

It sounded like an AI generated voice, which seemed impersonal. Also, there wasn’t really an explanation to his strategy, nor was there a reason as to why it would or would not be the best. And lastly, it seemed like too short of a video, I would have much preferred a 20 minute video with everything than a 10, 3 minute videos.

I like how this video made me very curious in very little time, and then let me decide how much more time I wanted to invest thinking.

A good video that gives us a interesting logic challenge to discuss. I think IS worth It to see the following videos in the series.

This video deserves atention ... although I'm not sure if it is suitable to be include in the SoME competition... It is a good thing to expose the author's philosophy about how to try to learn some math through ingenious puzzles ... and more than math a new way of using logic in puzzles... In spite of its merits around the game with Alice and Bob, it lacks of some explanations of the concepts involving distributions and probabilities... He mentions those and goes on talking... This video is well done but is not easy understandable for people without a solid math background...

really interesting subject. Just wish you woudln't have so much text on the screen and explained throught processes more.

great explanation of video with answer 7 but i still don't get the generalized one...

the text to speech voice is quite inconducive to listening attentively; and the video is quite weak as a standalone submission (the explanation video linked inside may have been the better submission)
