Ke y to the alliance is the idea that\, for a healthy variety of quantum fiel d theories understood as effective theories\, a separation of scales enabl es the aspirant realist to identify "the right variables" for effective ph ysics\, and frame her realism in their terms. In this talk\, I'll explicat e the alliance between physicists' effective theory technologies and philo sophers'—specifically\, scientific realists'—aspirations to understand our best physics as revealing deep truths about the physical world. Then I'll develop a challenge to the alliance in the form of what I call scale invaders—something\, I'll argue\, working physicists should be hoping fo r\, despite the trouble they make for scientific realism.\n LOCATION:https://researchseminars.org/talk/3cqfs/39/ END:VEVENT END:VCALENDAR
