see also Cambridge. The Cambridge Bubble is the force field projected by the University Library tower, and has a radius that includes all univeristy-owned sites in town, and stops at the reality checkpoint lamppost in Parker's Piece. The bubble's effect is to cut the students and staff of the university off from the 'real world'. Outside events cannot break through the bubble. The bubble's distorting effects also effect students' abiltiies to socialise, measure time, think logically, and can cause mental disturbance.
'Since she entered the Cambridge bubble all she thinks about is her once-fortnightly trip to Coco's, essay deadlines and where her next cafe latte is coming from.'
