The powers of 10 — nanotechnology Examples from biological and mechanical realms illustrate various “orders of magnitude” (powers of 10), from 10⁻² meter down to 10⁻⁷ meter.

Richard Feynman’s 1959 lecture, "There’s Plenty of Room at the Bottom," is considered a foundational moment for nanotechnology because it introduced a visionary framework for extreme miniaturization.

Feynman challenged his audience to consider the physical possibility of manipulating matter at the atomic and molecular scale. By using the example of writing the entire Encyclopædia Britannica on the head of a pin, he illustrated that the laws of physics do not prohibit the construction of objects at such small dimensions. He drew inspiration from biological systems, noting that cells function as tiny, active machines, and proposed that humans could similarly manufacture objects that maneuver at that level.

Furthermore, Feynman hypothesized that gaining control over the arrangement of atoms would unlock an "enormously greater range of possible properties" for substances. While the immediate lack of tools to visualize or manipulate matter at this scale hindered progress at the time, his lecture provided the conceptual roadmap that inspired future scientists, such as K. Eric Drexler, to pursue the development of molecular machines and atomic-scale engineering.1
