; Learning Landmarks
: '''Ebbinghaus’s Experiments (1885)''' → The first-ever scientific study of memory, where Ebbinghaus memorized "Nonsense Syllables" (like DAX or BOK) to see how fast he forgot them.
: '''Pimsleur Language Learning''' → A famous audio-based method that uses "Spaced intervals" (5 seconds, 25 seconds, 2 minutes) to teach you a new language without writing anything down.
: '''Medical School Anki Culture''' → Modern medical students use massive "Anki Decks" (like Zanki) to memorize the 20,000 facts needed to become a doctor, proving that SRS works for high-stakes learning.
: '''The FSRS Algorithm''' → A new "Free Spaced Repetition Scheduler" based on advanced math that is 15% more efficient than the older "SM-2" algorithm used for 30 years.
