But what is the Central Limit Theorem?3Blue1BrownI've watched the Central Limit Theorem video. And so I suggested by getting item 2, or not getting neither of the items, many times, your actual chances of getting item 1 increases over time, since the probability of a random set over multiple cycles is supposed to form a bell curve shape, and so getting only one of the outcomes multiple times would yield for there to be sets of data for the other outcomes too.

Exploring How Computers WorkSebastian Lague…about how that all works, but basically it's a two step process: 1) invert the signals, 2) add binary 1 to that result. Sebstian's video discusses it here: The OR going into them is just something temporary I put there to send a "1" binary signal into the XORs which is to toggle on 'subtraction' mode. When that 1 goes into the XORs then they

This list was put together by reading Reddit threads and recording which videos people linked. It's a sample rather than a census, and nothing here is ranked by popularity: a mention can be praise, a question or an argument, so each page says which it was.
Thumbnails and embedding were checked against YouTube when this site was built, but full playback wasn't tested and some videos may be blocked in your region. 10 mentions could not be traced to a working video and were left out, along with 29 links that were off topic. How this list was made.
