A Great Sorting

“…we are witnessing a Great Sorting within the library, a matching of different kinds of scholarly uses with the right media, formats, and locations. Books that are in high demand; or that benefit from physical manifestations, such as art books and musical scores; or that are rare or require careful, full engagement, might be better off in centralized places on campus. But multiple copies of common books, those that can be consulted quickly online or are needed only once a decade, or that are now largely replaced by digital forms, can be stored off site and made available quickly on demand, which reduces costs for libraries and also allows them to more easily share books among institutions in a network. Importantly, this also closes the gap between elite institutions such as Yale and the much larger number of colleges with more modest collections.”

Quantumcomputing For The Very Curious

“This essay explains how quantum computers work. It’s not a survey essay, or a popularization based on hand-wavy analogies. We’re going to dig down deep so you understand the details of quantum computing. Along the way, we’ll also learn the basic principles of quantum mechanics, since those are required to understand quantum computation.

Learning this material is challenging. Quantum computing and quantum mechanics are famously ‘hard’ subjects, often presented as mysterious and forbidding. If this were a conventional essay, chances are that you’d rapidly forget the material. But the essay is also an experiment in the essay form. As I’ll explain in detail below the essay incorporates new user interface ideas to help you remember what you read. That may sound surprising, but uses a well-validated idea from cognitive science known as spaced-repetition testing. More detail on how it works below. The upshot is that anyone who is curious and determined can understand quantum computing deeply and for the long term.”

Looks like I’m going to have to brush up on my math.
