I was watching a cartoon with my niece. Most of the time, cartoons have fairly simple things like 1+1=2 and so on. But this time I saw an equation that looks rather complex. I made a thread before about this, and tons of people replied. If I can tell by what's visible, it's an equation for time dilation. Coincidentally, the episode was about Time Travel. (The Protagonist in the photo, met herself in the beginning of the Episode, with a warning from her Future self getting cut off mid-sentence due to a finite amount of time she could spend in the past.) Even though it's not important, I thought it was interesting and it would give everyone something to mull over for a few minutes. Sorry for the poor angle, this was the best one available in the episode.
