After some years at the convent several things happened. We outgrew it; the church wanted it back; various compromise arrangements whereby we would enlarge it and then give it back after many years to the church and so on didn't work. So... so we left and we occupied a, what was essentially a dental suite, for some years. That wasn't very satisfactory but the Institute throve anyway. But it was not a very good home. And finally we acquired the Hurley Renfrew mansion overlooking the city, and we have now expanded it. The expansion will be finished in August or so and we won't have six in an office any more. I hope we can get down to two or three in an office. Six in an office may be wonderful for interaction, but it's not very good for thought. We have promised ourselves not to increase the number of resident researchers at any one time beyond 50. We had something like 35 to 45, typically, and now I hope we don't raise the number more than... by more than a very few and keep to our promise to ourselves that it won't be more than 50 because the character of the whole institution would change greatly, I think, if we had more than 50. And we'd be back to crowding, moreover, which would be a shame. So the people come for a day or a week or a month or a year or two years and co-operate across disciplinary lines and form informal research networks, communicating by email and fax and visits and so on, and study all sorts of marvelous problems in all those fields that... that we mentioned.
