Abstract
A negative contains all the information for the final photographic print. But held up against the light, the negative often appears glaring and garish—certainly unfamiliar and sometimes difficult to recognize. Immediately after exposure in the quiet acrid environment of the darkroom, the positive enlargement is initially invisible and then starts to appear so faintly that it is scarcely detectable; only with patience as it reacts to the harsh chemical baths into which it was plunged does it emerge into a sharp, detailed, and nuanced image. In the shadows cast by the negative, as the resultant positive emerges from the nearly unrecognizable past, it is surprising and gratifying to discover a memory of the initial moment of exposure. This metaphor serves as an apt though abstract description of the experiences described in this essay.
期刊介绍:
Since its inception in 2010, the Annual Review of Condensed Matter Physics has been chronicling significant advancements in the field and its related subjects. By highlighting recent developments and offering critical evaluations, the journal actively contributes to the ongoing discourse in condensed matter physics. The latest volume of the journal has transitioned from gated access to open access, facilitated by Annual Reviews' Subscribe to Open initiative. Under this program, all articles are now published under a CC BY license, ensuring broader accessibility and dissemination of knowledge.
