• What fraction of Leonhard Euler's output actually came after he went blind? Two Tier-2 sources conflict ('half of his output' vs '≈a third in the first seven years') — new findings on the figure's origin and an unresolved denominator

• Leonhard Euler produced a large share of his roughly 850 works after going blind — but the exact fraction is unsettled, with two Tier-2 sources giving conflicting figures

• Abraham Nemeth kept his braille math code secret until a colleague's unplanned request for a table of integrals forced its disclosure — a documented mechanism for why private notation stays private by default

• Norberto Salinas and Abraham Nemeth each independently invented a personal braille mathematics notation in the mid-20th century, extending the blind-mathematician pattern to more cases and countries
