    Paul–Great post!! Novelty ties of all kinds are dumb, the ones that double identify the wearer as geek are the worst.

    As a designer and manufacture of novelty items, I am offended.

    Apparently, wearing them at faculty meetings brings up a whole other layer of social complexity. You probably should have tenure before wearing it.

    They are great for wearing around the department if you’re a professor and like to dress formally. I haven’t made up my mind whether it’s a big no-no to wear one at an ACS meeting.

    Don’t wear one at a conference, and if you do, don’t pose for pictures.

    Welcome back Paul ! You got me started in the game (now posting on “The Skeptical Chymist” in the “Chemiotics” section). Will you revive ChemBark?

    Hey Retread. ChemBark will rise again, but not for 6 months or so.

    Hello Paul. Glad you’re (sort of) back.

    If you’re social inadequate enough, the PTN is unnecessary. Doodling structures I find helps – it’s not intentional to repel bystanders, but it’s cheaper and less ugly than the necktie.

    Oh yes, it must be so. I am so sad, Paul, to find you back here with no progress. What can we do, as the community of chemists ? We all love you and wish you a successful comeback. President Obama also loves you in all his glory and truthfulness and he welcomes you. Please join him in his successful team with your Harvardmates.

    Good luck,

    Thanks for the advice, Paul – what is the license of the image? I would like to use it for (where CC-BY-SA is the default).

    Feel free to use it for whatever.
