This document discusses how humans learn and form memories. It states that we remember 10% of what we read, 20% of what we hear, 30% of what we see, 50% of what we see and hear, 70% of what is discussed with others, and 80% of what we experience. We remember 95% of what we teach others. New memories are formed through neurons and synapses in the brain. There are three stages of memory: sensory, short-term, and long-term. Short-term memory can only hold 7 pieces of information for 20-30 seconds. Various techniques can help with long-term memory including acronyms, rhymes, chunking information, and practicing retrieval.
