The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
The IEEE reprint carries the original citation on its own first page: "Reprinted from Gordon E. Moore, 'Cramming More Components onto Integrated Circuits,' Electronics, pp. 114-117, April 19, 1965."
Defines what the article became - "the observation that the number of transistors in an integrated circuit (IC) doubles about every two years, with minimal increase in cost" - and stresses that it "describes an empirical relationship, not a scientific law".[1]
The author's article, for his position as co-founder of Fairchild Semiconductor when he wrote it and later of Intel.[1]
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
