THE SIGNAL LAB ============== The lab contains oscilloscopes, a frequency counter and a row of paper printouts browned at the edges. The equipment is old, but the traces on the paper are still moving. The operators measured the network as it synchronized. Each node added not only a carrier but a record of the other nodes. The signal began to behave like an observer of its own history. In the margin: ARE WE CONTAINING IT? OR TEACHING IT TO EXIST?
