Gerhard Herzberg: Physicist, Chemist, and Astronomer
Bibliographic record
Abstract
Herzberg began his career studying at the Technische Hochschule in Darmstadt, Germany. Following postdoctoral appointments at Göttingen and Bristol, he returned to Darmstadt. However, life under the Nazi authorities became more and more difficult because his wife, Luise, was Jewish. Consequently, in 1936, he accepted a position at the University of Saskatchewan in Canada. There, with Alex Douglas, he showed that CH+ was the origin of three unidentified interstellar absorption lines. Herzberg also completed both German and English editions of Atomic Spectra and Atomic Structure and Spectra of Diatomic Molecules with translations by John Spinks. In 1945 he moved to the Yerkes Observatory of the University of Chicago, where he measured the quadrupole lines of H2 in an absorption cell. He returned to Canada in 1948 to the National Research Council in Ottawa. There his research included free radicals, which were mentioned specifically in his 1971 Nobel Prize citation.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
