Sorry for being so vague, but I am not sure how to look this one up myself. enter image description here

I've had a shirt with this on it for something like 20 years now and everyone I've shown it to says they don't know what it is. I guess I'm not surprised. Does anyone here know what this equation means?

  • Also, the shirt must have superb quality if you can wear it for so many years... – Mau314 Feb 03 '18 at 17:38

    @user14717 - Bubbles probably knows more about math than I do. But I have the common sense to not wear it around. What if it's a higher mathematics joke like the equivalent of 1 + 1 = 9. anyone who can read it might be laughing that you would wear such an incorrect equation and get a good giggle at your foolishness... never know. – Kai Qing Feb 03 '18 at 17:39
  • @Mau314 Back in the day, things were made to last! –  Feb 03 '18 at 17:39
  • No, it's in ruins. I kept it because I never knew what it was. It's virtually unrecognizable now, but I can piece together the symbols – Kai Qing Feb 03 '18 at 17:41

    you could use the tag quantum mechanics^^ – Fakemistake Feb 03 '18 at 17:43

This is Schrödinger's equation. Try to read this before your question gets removed by the moderation :)

    Awesome! thank you so much. Funny thing is I have a sticker on my car that claims to be schrodinger's equation.... hmm – Kai Qing Feb 03 '18 at 17:40

    Don't tell me - your car will start only half the time? – Arnaud Mortier Feb 03 '18 at 17:41
  • My car is theoretically in the garage. But it might not be also. Kind of like a joke about the possibility of it being stolen while I'm not watching. I doubt anyone has ever made that connection though. – Kai Qing Feb 03 '18 at 17:43
  • @KaiQing You don't know if your car is in the garage. It's there or it's not there. You have here a mixed quantum state. You have to go in your garage to see if the car is there or not. This is then a pure quantum state. – Fakemistake Feb 03 '18 at 17:54
  • Cop: do you know at what speed you were driving?!! @KaiQing: no clue - but I know exactly where I was. – Arnaud Mortier Feb 03 '18 at 17:56
  • lol. then my snarkiness gets me thrown in a jail cell where I know where I am but to them I am either in the cell or not. I compared the shirt to the car. Yeah, I can see it now. Where the upside down delta is - the sticker uses a longer form, but it looks like I should have at least recognized enough to think it might be schrodinger's instead of just being totally clueless. Course, it's not like I carry the shirt around. I forgot I even had it until a few months ago. – Kai Qing Feb 03 '18 at 18:12
