An Easter Egg

When the institute's logo was designed in 1994, we thought it
might be neat to incorporate an 'easter egg' into the design. The net result was the 'tr(I)' concept.

Can't find that easter egg? ... in addition to fulfilling its primary role as an acronym, 'tr(I)' also denotes the trace of an identity matrix. This is admittedly a little esoteric, but then that's half the fun. At the very least, it helps to brighten up the small talk at conferences. The tr(I) pun is a new and rich field of research which has only just begun to be explored. Several people have already provided some decidely witty embellishments, which are listed below:

Jeff Frankel (U of California, Berkeley) spotted a neat geome*tri*cal trick. He suggests placing the tr(I) logo within a tri-angle instead of a square (see the home page logo). Our DTP machinery brought this Frankelism to life... something to consider next time the stationery runs out.

David Garvin (Morgan Grenfell, London) suggests the following gem as a motto:

We tr(I) harder.
For difficult problems, this can be modified to:
Still tr(I)ing.
Or perhaps ...
If at first you don't succeed, tr(I), tr(I), and tr(I) again.

Marni Sheppeard (UNSW) took time off from theoretical physics to point out that the trace of an identity matrix is equal to its dimension (dim). As such, she concludes that tr(I) should really be called the dim(n) institute .
Perhaps this is quite fitting: after all, economics is said to be the dim science .
[Apparently physicists also believe that economists suffer from 'physics envy', but that's another story.]
