What does it mean that version your atoms?

Ideas evolve. Your system should let you see how any atom changed over time — not just what you believe now, but what you believed before and why it shifted.

Example: In 2019 you wrote a note: 'Remote work reduces productivity.' In 2021, after leading a distributed team through a pandemic, you wrote an updated version: 'Remote work reduces productivity for teams that never built trust in person.' In 2024, a third version: 'Remote work reduces synchronous collaboration; async-native teams outperform co-located ones on complex knowledge work.' Three versions. Each one captures something the previous one missed. None of them are wrong — they are increasingly calibrated. Without the first two versions, you cannot see the trajectory of your own learning.

Try this: Find a belief you have held for at least three years — about management, about a technology choice, about how relationships work. Write down what you believed three years ago as Version 1. Write your current position as Version 2. Then write one sentence describing what evidence or experience caused the shift. You now have a versioned atom with a changelog. Store all three together.
