    +1/2 h and -1/2 h

    Fucking hate the people that insist on using only half of the number as if it was a real value. At least say you are working with natural unities or something.

      Except in this context the question is “how many blocks away is your house?” Where “5” is a completely valid response

      It’s h-bar, not h. And it really does make sense if you look deeper I to the math.

        Using “+1/2” and “-1/2” as vector labels is fine. Using it on the context of “the spin can have those 2 values here” for laypeople without further explanation is just making the subject less accessible.

        Also, yeah, I was too lazy to search for the unicode ħ.

          This might be a meme making fun of the inaccessibility of modern physics for laypeople.

      Or how about - “Walk around the block TWICE and it’ll be right there, you can’t miss it.”
