Mnemosyne (software) available from the author, Peter Bienstman, upon request. Mnemosyne (software) Mnemosyne (named for the Greek goddess of memory, Mnemosyne) is a line of spaced repetition software developed from 2003 until the present. Each day, the software displays each card that is scheduled for repetition. The user then grades their recollection of the card's answer on a scale of 0-5. The software then schedules the next repetition of the card in accordance with the user's rating of that particular card and the database of cards as a whole. This produces an active, rather than passive, review process. Mnemosyne is written in
57 Mnemosyne 57 Mnemosyne Mnemosyne ( ; minor planet designation: 57 Mnemosyne) is a large main belt asteroid. It is an S-type asteroid in composition. It was discovered by Robert Luther on 22 September 1859 from Düsseldorf. Its name was chosen by Martin Hoek, director of the Utrecht Observatory, in reference to Mnemosyne, a Titaness in Greek mythology. The orbital period of this asteroid is close to a 2:1 commensurability with Jupiter, which made it useful for perturbation measurements to derive the mass of the planet. Photometry measurements made at the Oakley Observatory during 2006 produced a lightcurve with a rotation period
