Caesium Atomic Clock

Famous quotes containing the words atomic and/or clock:

“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)

“He makes his voyage too late, perhaps, by a true water clock who delays too long.”
—Henry David Thoreau (1817–1862)
