so does anybody know how a video with a misaligned log scale even looks? like what does a log scale even mean for a video? 172.71.99.18 19:30, 22 January 2024 (UTC)mstrofcmdy209
- I think he's suggesting that the video shows the changes in a graph over time, and the misalignment could also change during the video. Barmar (talk) 20:47, 22 January 2024 (UTC)
- Imagine that a plot is just a 2D picture, or even more fundamentally as a function taking two variables and returning a pixel color. Changing an axis of the plot to be logarithmic is equivalent to applying a non-uniform scaling to one of the input variables to that function. In this comic that non-uniform scaling has instead been applied along an axis that does not correspond to either the X or Y axes but instead some combination of the two. A video can similarly be thought of as a function of 3 variables (X, Y, T) and so the non-uniform log scaling could be applied along an axis that is some combination of the X, T, and T axes. 172.71.154.252 23:37, 22 January 2024 (UTC)
- it's time, probably -jade 172.69.64.198 20:28, 22 January 2024 (UTC)
- LOG is also a video format, though I don't understand this well enough to discern whether this might be part of the joke or an unintentional coincidence.172.70.86.80 09:59, 23 January 2024 (UTC)
There seems to be a subtle relativity joke in the title text, with misalignments in both time and space being a reference to spacetime. 172.71.154.42 (talk) 00:05, 23 January 2024 (please sign your comments with ~~~~)
Shall we try to straighten out the plot with regards to the axes, leaving the log stripes all wavy? For kicks? -- Enfield (talk) 02:14, 23 January 2024 (please sign your comments with ~~~~)
