Feynman's vision of nanotechnology

Definition

Feynman's vision of nanotechnology refers to the groundbreaking idea proposed by physicist Richard Feynman in his 1959 lecture 'There's Plenty of Room at the Bottom,' where he imagined manipulating matter at the atomic and molecular levels. This concept laid the foundation for modern nanotechnology, suggesting that the arrangement of atoms could lead to revolutionary advancements in materials science, medicine, and electronics.
