Compounds Like Interest

Richard Hamming’s line, quoted in Vivek’s essay How to Be Good at Research, is that knowledge and productivity compound like interest. It’s a small claim with a sharp edge: the daily edges of a good researcher look trivial in isolation, and the careers they add up to “look like luck from the outside.”

The inputs that compound are unglamorous and all under your control: what you read, what you write down, how fast your experiment loop runs, and who you argue with. None of them pay off today. All of them pay off on a curve.

The multiplier the essay singles out is generosity — replicating a result, releasing a tool, explaining something hard. The return arrives sideways, months later, as a collaboration or a reference you didn’t plan. A colleague who kills your bad idea before you’ve sunk three months into it, as the essay puts it, “is worth more than compute.”

Which leaves one practical instruction, the only one that really matters for anything that compounds: start earlier than feels necessary. Future you already knows this was the cheap part.
