Ebbinghaus Spaced Repetition Planner (1-3-7-21-60 Day Intervals)
Scientifically scheduled review intervals interrupt memory decay and convert transient information into permanent semantic knowledge.
The Ebbinghaus Forgetting Curve
Hermann Ebbinghaus discovered that without review, humans forget ~70% of newly learned information within 24 hours. Reviewing at spaced intervals (Day 1, 3, 7, 21) flattens the curve, locking knowledge into permanent long-term memory.
