If the universe is multiply-connected and sufficiently small, then the last scattering surface wraps around the universe and intersects itself. Each circle of intersection appears as two distinct circles on the microwave sky. The present article shows how to use the matched circles to explicitly reconstruct the global topology of space.

Here I summarize P5-WG (New/Alternative Physics Working Group) of LCWS2000@FNAL, held on Oct 24-28, 2000. There were 13 talks altogether, 7 talks on collider signals from new particles/interactions and 6 talks on extra dimensional physics. We had very active and hot discussions among participants for those new/alternative physics/ideas. In bottom table, I show those 13 speakers' names and titles.

Measurements of di-jet production at HERA provide an important test of NLO QCD calculations. It is also a source of information about the partonic content of the photon, complementary to the measurements in ee experiments. In this article we review the status of the photon structure studies with particular emphasis on HERA measurements.
