Meaning and Definition
A unit of energy used in nuclear physics, equivalent to the energy released in the fission of one uranium-235 nucleus, approximately 180 MeV.
The term is also used to honor Lise Meitner, the Austrian-Swedish physicist who contributed to the discovery of nuclear fission. It can refer to concepts, elements (like meitnerium, element 109), or awards named after her.

British vs American Usage
Differences
No significant differences in usage; the term is standardized in the international scientific community.
Connotations
Carries connotations of scientific discovery, nuclear physics, and the historical contribution of Lise Meitner, often with a note of her overlooked recognition for the Nobel Prize.
Frequency
Equally rare in both varieties, confined to highly specialized physics literature, history of science texts, or discussions of chemical element naming.

FAQ
Frequently Asked Questions
No, it is an extremely rare and specialised term used almost exclusively in nuclear physics and the history of science.
In British English, it is /ˈmaɪtnə/ (MIGHT-nuh). In American English, it is /ˈmaɪtnər/ (MIGHT-ner).
'Meitner' is a unit of energy. 'Meitnerium' (Mt) is the name of the chemical element with atomic number 109, named in honour of Lise Meitner.
Lise Meitner was a key contributor to the discovery of nuclear fission. Despite this, her colleague Otto Hahn alone received the 1944 Nobel Prize for Chemistry for the discovery, a decision widely criticised by the scientific community.
A unit of energy used in nuclear physics, equivalent to the energy released in the fission of one uranium-235 nucleus, approximately 180 MeV.
Meitner is usually formal, scientific, historical in register.
Learning
Memory Aids
Mnemonic
Think: 'MIGHT-ner' - Lise Meitner had the MIGHT to help discover fission, and a 'meitner' is a MIGHTY small unit of energy from it.
Conceptual Metaphor
