Meitner–Frisch interpretation of fission
E159822
The Meitner–Frisch interpretation of fission is the 1939 theoretical explanation by Lise Meitner and Otto Frisch that identified nuclear fission as the splitting of heavy atomic nuclei with a corresponding release of enormous energy, laying the groundwork for nuclear physics and atomic energy.

How this entity was disambiguated
This entity first appeared as the object of triple T1388466 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
