▸ The reading
interpretive · artMeitnerium carries a correction: Lise Meitner co-discovered nuclear fission and watched the Nobel go to Otto Hahn alone, and element 109 is the table's standing redress. Its chemistry is essentially unstudied — single atoms, gone in moments. Some seats exist to hold a name where a prize should have been.
The science below is cited as science; the symbolic layers are flagged as interactive art.

▸ The lenses
▸ Discovery
Peter Armbruster + Gottfried Münzenberg + colleagues at GSI Darmstadt — bombarded bismuth with iron ions · Germany · 1982
▸ Stellar origin
Human-madeGroup-9 transactinide. Longest-lived isotope ²⁷⁸Mt has a half-life of seven seconds.
▸ Reactivity
Chemistry largely unstudied (sample size: single atoms)Half-lives too short for the gas-chromatography techniques that worked for lighter transactinides. Properties are theoretical predictions.
▸ Applications
- Heavy-element synthesis research
- (No commercial applications)
- (No practical bulk uses)
- (No medical uses)
▸ Curiosity
Named for Lise Meitner — co-discoverer of nuclear fission whose Nobel was given to Otto Hahn alone, an injustice the element name partially redresses.
