Probable attribution
A source trail connects this quotation to Albert Einstein and Remark to scientist Herman Francis Mark, but the exact English wording has not been confirmed in a primary text. The attribution is therefore probable rather than definitive.
Likely origin: Remark to scientist Herman Francis Mark
Review the attribution sourceAbout this quote
This page records the wording "A theory is something nobody believes, except the person who…," which centers on theory, something, nobody. A concrete trail points toward Einstein, but the exact English form remains unconfirmed; the page therefore labels it as attributed to him while preserving its science and life context.
When to use it
- Use "A theory is something nobody believes, except the person who…" in a science discussion, then ask which concrete claim the wording makes.
- Compare its treatment of theory with something in a lesson, essay, or editorial note before drawing a conclusion.
- Before sharing it as Einstein's exact words, display the attribution caveat and follow the evidence link recorded on the page.
