Astronomy is many disciplines
From Solar System to Galaxy to CosmosFrom Big Bang to current epochFrom gigayear stasis to explosive detonationPhysics in extreme regimesEarth’s broadest contextCivilization’s ultimate master

Experimental designObservations serve empirical purpose(s)Archival science is not differentPhilosophical issues can’t be ducked:
What is a detection? What is an object? What is a process?
Software can help or hinder

Time domainCan’t afford the cycle overheadMust speed up by several orders of mag.
but also…Schedule is no longer a free parameterPreparation must be complete & explicitContext is everything (sample selection)Competition is fierceThus need new observing mode
