Probable attribution
A source trail connects this quotation to Albert Einstein and The Evolution of Physics: From Early Concepts to Relativity and Quanta, but the exact English wording has not been confirmed in a primary text. The attribution is therefore probable rather than definitive.

About this quote
This page records the wording "Fundamental ideas play the most essential role in forming a…," which centers on fundamental, ideas, essential. 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 creativity context.
When to use it
- Use "Fundamental ideas play the most essential role in forming a…" in a science discussion, then ask which concrete claim the wording makes.
- Compare its treatment of fundamental with ideas 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.
