These animations are largely made using manim, a scrappy open-source python library: https://github.com/3b1b/manim

If you want to check it out, I feel compelled to warn you that it's not the most well-documented tool, and it has many other quirks you might expect in a library someone wrote with only their own use in mind.

If you want to contribute translated subtitles or to help review those that have already been made by others and need approval, you can click the gear icon in the video and go to subtitles/cc, then "add subtitles/cc". I really appreciate those who do this, as it helps make the lessons accessible to more people.

I'm tempted to give a dislike and ask my partner to give a like for a more accurate rating of this video.

Also a good approach: reading the 1 star reviews and checking for grammar/spelling and signs of stupidity.

Now if 90 % of reviews on Amazon weren't fake this would actually be useful.

Your animations have become astoundingly good and nuanced over the years. The way all the (50 choose 48) outcomes were displayed, starting slow, going faster in the middle and then ending slowly again... THAT'S a satisfying detail.

This is all assuming that the buyers aren’t paid to give positive reviews.

Sooo.... who is going to write a Chrome Extension to do the math for us when shopping on Amazon?

Part 2 will be out soon. I'm going to implement changes based on supporter feedback, and in the meantime am also working on a video simulating epidemics. Thanks for your patience, and stay tuned! We'll also talk more later about how to address the ways this obviously simplified model differs from reality. First, we have to establish the basic building blocks to work with.

Some people have asked about if the smaller graph around 10:40 should actually be much taller, since “the area under it should be 1”. If it was a distribution, this would absolutely be true, but those two graphs are simply functions, where s is a variable, not probability density functions for s. To see how that pdf comes about, that’s where Bayes’ rule comes in, to be covered in part 2.

You'd have to trust reviewers to know what the hell they're talking about to begin with. I certainly don't.

"All Prices Pi Publishing" is selling the $75 book for $314.15. Go figure.

0:20 You buy from the one that has "Fullfilment by Amazon" so you get the faster delivery xD

When I see ten perfect ratings, I assume ten friends of the seller bought the item, gave the item a perfect rating as "Verified Buyers", and then received refunds offline.

The beauty of this channel is that, even though I might be well versed with all of its content concept-wise, I still enjoy very much watching these videos. I'm just delighted to see how you choose to present concepts, the graphical effort to show them clearly, in coordination with speech. Sometimes in incredibly revelaing ways. This is what teaching is truly about, and it is kinda sad how often teachers themselves mistake their job as "giving concepts to students" (...and testing them) (or something along those lines). Your work is very inspirational, instructive, enjoyable. I'm so happy that I know you - and big props to each one collaborating to make these videos. I'm confident in saying that you're like friends for many of us, even though we don't know you in person!

An actuary who is tired of calculating give you another solution:
- Surely the one with 200 reviews is better. They get more customers even offering the same price!

1:51 wow i have constructed this method on my mind long ago, without reading anything on the subject. Interesting.
