The discussion centers on the impressive setup and movement of balls in a video, with participants expressing skepticism about the feasibility of achieving such precision by hand. Many believe the initial arrangement of the balls suggests advanced technology, possibly involving electromagnets or computerized systems. It is revealed that the video is actually CGI, with references to similar Marble Madness videos available online. Participants note the increasing realism of animated content, leading to confusion about what is real versus CGI. There is a call for clearer labeling of CGI in video titles to help viewers distinguish between animated and real footage.

Something I never would have suspected.

I'm not as impressed by how they are moving now as I am that the balls were initially set up perfectly.

I thought the same. I'd think you'd have to have the balls held by electromagnets that are then released sequentially. It seems virtually impossible to do this by hand. Having the channels made so precisely that the balls all move the same way must also be some computerized thing.

It may have been inspired by this simulation done 3 years prior.

Guys, it's CGI. These kinds of Marble Madness videos are all over the innertoobs.




This one is actually labeled "CGI animation":

Now I feel like a caveman confused by fire. A lot of the animated Youtube videos have fooled me recently. They have become incredibly realistic. This one is clearly identified as animated using Blender in the Youtube description. I wish that Youtube had a policy that the title indicate CGI.

I once looked into Blender. I concluded that life was too short to learn Blender.

Thread 'Erroneously  finding discrepancy in transpose rule'
Obviously, there is something elementary I am missing here. To form the transpose of a matrix, one exchanges rows and columns, so the transpose of a scalar, considered as (or isomorphic to) a one-entry matrix, should stay the same, including if the scalar is a complex number. On the other hand, in the isomorphism between the complex plane and the real plane, a complex number a+bi corresponds to a matrix in the real plane; taking the transpose we get which then corresponds to a-bi...
