   Corrected three issues: fixed the Maxwell-Faraday age gap from twenty years to about forty (Faraday born 1791, Maxwell born 1831); added Miller's (1956) attribution and Cowan's (2001) revision to the '~7 items' working-memory heuristic, noting later research suggests closer to four chunks for most tasks; and softened the BNEF battery-cost forecast conclusion from proving first-principles reasoning generally more accurate to illustrating the difference in approach in this one instance, since a single case cannot establish general superiority of one reasoning method over another.

   What the page claimed

   The article said Maxwell was twenty years younger than Faraday, presented the ~7-item working-memory limit without qualification, and concluded that the BNEF battery forecast proved first-principles reasoning produces better predictions than analogical reasoning in general.

   What was corrected

   Corrected the age gap, added the Miller/Cowan attribution and qualification, and scoped the battery-forecast conclusion to the single case rather than a general claim.

   Why: The age gap was a factual error, and the working-memory and battery-forecast claims were stated more definitively than a single heuristic or case example supports. Corrections fix the date and add appropriate scope rather than adding new sources.

   There was no $65M NASA quote; in 2002 Musk sought to buy Russian ICBMs/rockets and was quoted high prices by Russian sellers.

   Before

   In 2002, Elon Musk wanted to buy a rocket. NASA quoted him roughly $65 million per launch. The Russian space agency offered slightly less, but still...

   After

   In 2002, Elon Musk traveled to Russia to buy refurbished intercontinental ballistic missiles to use as rockets. Russian sellers quoted him prices in the tens of millions of dollars...

   Why: Verified live: the correction was already applied to the article body exactly as suggested. FAQ/excerpt/meta_description/seo_keywords contained no leftover reference to the unverified NASA quote. No further action needed.
