Note to future viewers: at 9:58 when he says blue sets he actually means the yellow rectangular sets A_i, because the colours have been inverted!

Thanks so much. I have a rare disease called corneal neuralgia which involves photophobia, so this dark version aids me a lot and helps relieve a lot of tension that distracts my focus.

Definitely one of my favourite series on this channel. It is insane how well you explain these concepts. I feel like most math channels on youtube either strive for maximum simplicity, which makes the videos very easy to understand but also pretty shallow, or they keep them in a format of a lecture which often goes very in-depth but doesn't feel much more accessible than a book or lecture notes. You however, especially in this series, manage to do both - keep the videos captivating and easy to understand while still conveying all the important ideas, enough to get a good understanding of like 80% of the core concepts and then be able to easily go through any book on the topic to fill in the details.

I knew equation wise what the sigma algebra and the conditions meant but visualizing it with Venn diagrams really helped understand the matter. thanks a lot. sigma algebra feels real now just like numbers on the number line. earlier it made no sense, just existed because some dude said so.

Is there any significant difference of illustration between this dark version and the bright version which I have followed before?

instead of re-uploading all your videos in dark mode u can just make a channel called "the dark side of mathematics" lol

(but seriously dark mode makes videos 100x better on my eyes)

i know its wrong to be so demanding and i really apologize for it. But is it possible for you to make two playlists which include relavant maths videos for financial engineering and machine learning?

is there a particular reason closed under uncountable union is not necessary?

Black background is much better than the dark blue imo
