    I’d like to clean up some of the QM entries. In particular, Aleks Kissinger (Bob Coecke’s student) has not been very active since his first week or two and left a lot half-finished under quantum information.

    General question:

    • Since this is the nLab it seems like any “linear flow” in the QM entries ought to proceed through the categorical formulation of QM. Thus it seems like it would make sense to make quantum information more of an application and take a lot of the material there and put it under the main QM entry or the entry on quantum mechanics in terms of dagger-compact categories. In general, what do people think of this? I would really like the QM entries to flow more like the QFT entries and be a little less haphazard (at least they seem that way to me, but that may be just me).

    Specific questions I have:

    • As someone proposed in a query box, can we move the subsection on Hilbert space QM to the main quantum mechanics entry?

    • As per Zoran’s earlier suggestion, should we change “quantum mechanics” to “quantum physics” (or something)?

    • Under the graphical notation, Aleks suggested in a query box that the graphical notation sunsection be moved to the page on string diagrams. I know very little about the latter so I don’t know if this is appropriate. Please advise.

    My suggesion was totally opposite: quantum mechanics is not the same as quantum physics. Quantum physics is a wide subject including also experimental phenomena, quantum statistical mechanics and so on. Quantum mechanics is just the fundamental theoretical framework for quantum mechanical systems.

    Right. I guess that’s what I meant since I thought you originally wanted to change that entry’s name. But if you want to leave it, then that’s fine.

    What about the other stuff I mentioned?

    bump

    Anyone? I don’t want to do something and get yelled at for it but I think those entries could use some work.

    My suggestion:

    Try one idea, announce (here and in a new thread) what you did, gauge reactions.

    If reactions are positive, try some more.

    Yep yep. Agree with Toby. The only thing that bugs me (not saying you do this, but just some info) is to see material REMOVED from the nLab. If someone takes the time to write something on the nLab, someone else should not come along later and remove it (unless it is incorrect, but even then I think the idea could remain visible somehow to help avoid future people making the same mistakes). Instead, there can always be a way to incorporate prior material into new material without deleting content.

    Oh, definitely, I wouldn't remove anything. What I wanted to do was to make it flow better by shuffling things around a bit.

    But I could definitely use help on the strings thing since I don't have a handle on strings yet. In fact I'm not even close.

    Rule of thumb: if you think you know what you are doing, then do it. And announce it here. If you feel you might be out of your depth, then don’t write an entry, but ask a question.

    Will do. I'm in meetings today (with BP! woohoo!) but will get to it this weekend.

    with BP

    What, the oil spill company?

    Indeed. I'm acting as an independent consultant on certain aspects of the cleanup effort (as an aside, there are some interesting applied math problems that cropped up in what I've been doing). I have all sorts of stories about BP but I suspect this is not the place for them.
