   Oooh, Clifford. Can I have the blue hat on the right? (Flutters eyelids)

2. Travis on May 21st, 2006 at 4:33 pm

   I look forward to finding out more about the display of rockets and tools. Sadly the hats do not appeal to me nearly as much.

3. Clifford on May 21st, 2006 at 4:36 pm

   Kea, Yea, it’s pretty lovely isn’t it? Sadly, Harrods is closed now, and I must be checked in for my flight before it opens again. (So the eyelid fluttering, powerful as it probably is, won’t get the job done.) Sorry!

   And before anyone flutters at me (don’t get me wrong…I like the fluttering) to ask me for a hammer or a Saturn V rocket….. Same story.

   Cheers,

   Is this hat collection made with advanced rocket science or primitive tool science?

5. Clifford on May 21st, 2006 at 4:41 pm

   Actually, the Rockets and Tools were made with advanced Hat science and technology. Little known fact.

   Oh really…quite a twist on logical reasoning.

   did you get a new hat for your LA summer?

8. Clifford on May 21st, 2006 at 5:03 pm

   No… did not occur to me. Old one going strong. Incidentally, it was bought in a famous department store in Paris during the Strings 2004 conference there. So I could make a nice resonance of I got my next hat in a Beijing department store this June.

   Sigh. Oh, well. Not sure when I’ll get to London next. Last time I was in Europe I managed to skip London, in a feat of master traveling, on a budget 14 hour trip from Sheffield to Grindelwald.

    Just taking a wild stab at it.

    
    

    In this language, many counterintuitive features of quantum theory turn out to be properties shared by the category of Hilbert spaces and the category of cobordisms, in which objects are choices of “space” and emorphisms are choices of “spacetime”.

    What happened to the science that was supposed to be on this blog?

12. Clifford on May 22nd, 2006 at 8:40 am

    [Inserted comment:] Yes, folks… Dear Rufus still can’t stop himself or herself from reading, despite helpful suggestions, e.g., here and here, and still posts up amusing rude remarks to let us know (s)he’s here.

    LOL!

    Or are they groupoids of objects?

14. Plato on May 22nd, 2006 at 9:47 am

    I am sure we’ll get the full scoop on this when Clifford has time.

    I mean looking at the pictures above, does it seem natural?

    As a aging student, it is confusing.

    I quite literally grew up with much of that rocket collection in my house. My father researched, designed, engineered and managed the building of several of those payload delivery systems. He also helped evaluate and analyze the intelligent reports on some of the other systems from the Soviet era that are displayed their as well in your photo. Thanks for the precious memories just from that one image. Now if only i hadn’t been such a destructive little twit.

    Which of these hats would make good “thinking caps” for the Physicists here? Ummmmm…. the camoflage one with the red ribbon for Clifford, the turquoise one for JoAnne, the orange one for Risa and brown hats for Sean or Mark.

17. Clifford on May 22nd, 2006 at 5:57 pm

    Hey! Why can’t I have Kea’s blue one? (Although the other choice is nice too)

18. Kea on May 22nd, 2006 at 6:14 pm

    Because it’s mine!

19. Clifford on May 22nd, 2006 at 6:16 pm

    Oh. Good point. Ok.

    […] I love to go and look at all the displays of food (pictures all down the right of this post so far), some good plain old-fashioned theme-park Englishness (both on the part of the store and staff on the one hand, and the customers on the other), and also some of the other displays too. Recall the pictures of the hats from my previous post. Dear Reader (and I’m not just talking to men here), if you don’t go and wander in the women’s “soft accessories” section, where on earth would you ever see such wonderful composition? If anybody thinks less of you for wandering in there, tell them from me they’re an idiot. […]

    […] This year I was unable to do so due to a trip across the Atlantic concerning the birth of my sister’s son (details of the london trip here, here, here and here; Last link has a fun trip to Harrods and to the Science Museum). But my USC colleague Chris Gould -the chief organisational engine behind the fair- has prepared hundreds of photographs again, and you can go and have a look here, and see some of the project descriptions also.

    […] Quite different from the hats in Harrods - remember those? - but quite a splendid display idea all the same. […]
