The amusing thing about Computerphile is it makes me wonder how inaccurate or inexact Numberphile is, as I'm very knowledgeable about the former and clueless about the latter. Computerphile is unwatchable to me, they'll just say stuff that is flat out wrong, but I eagerly await each new Numberphile vid.

There's a term for this, I can't remember. You read a newspaper article about a subject you know, and can't believe how much in it is incorrect or misconstrued, then you read another article about a different topic and it seems fine.




It's similar. Two issues with Numberphile videos I can remember:

Their video on 1+2+3+... = -1/12 was so bad that another Math channel (Mathologer, which is highly recommendable btw) did a whole 40min video tearing it apart: https://youtube.com/watch?v=YuIIjLr6vUA

In their video on fluid mechanics, they say that the Navier-Stokes equations describe all fluids on earth, while they only show the incompressible version (without clarifying). The examples shown on screen at that moment also include a Ketchup bottle, and they don't discuss non-Newtonian fluids either (Ketchup is non-Newtonian, that's why you can get a lot of it coming out at once if you shake a bottle too hard). It's a bit nitpicking though, because apart from these missing caveats it's a great video (with a guest lecturer from Tom Rocks Maths, another great math channel).


Gell-Mann Amnesia

Out of curiosity, can you give a recent example of a video from Computerphile that was incorrect?


That's it! Thanks!

Recent videos? I haven't watched it in a while. But looking now, I immediately found an example, because the problems are always with the history. In the video below [1], the guy absolutely mangles the story of the byte and why it's 8 bits long. He turns what was a fuckup in the launch of the System/360, into some urban legend of IBM's technical superiority and vision.

"IBM said, 'Let's be brave! 8 bit characters!'"

FFS, no. IBM said (in summary), "Crap, we really wanted to use 7 bit ASCII - an evolution of the 6 bit teleprinter code, since we're on the federal standards committee, but ASCII peripherals won't be ready in time for the System/360 launch, so uh, let's use this 8 bit extension to our old 6 bit punch cards instead and wing it." It turned out to be a massive blunder. [2]

The System/360 still succeeded and its success meant a bunch of software was written for it, which all assumed an 8 bit byte, competitors copied IBM, and the rest of the market followed, but it took a decade or so. There's lots of fun stuff in the actual story - including the rich history of today's character standards which goes all the way back to the telegraph - to summarize without making things up.

I know you're asking about Computerphile, but this video explains how one of the Numberphile videos is wrong: https://www.youtube.com/watch?v=YuIIjLr6vUA


none of it is incorrect - it's just lacking in details that only someone in the field would see.

Numberphile probably has less "inaccuracies" - because maths can probably be summarized easier to the layman than computer science.
