| had a 63% chance of having at least one defective connection.
| The search for an end to this "tyranny of numbers" drove many
| research projects in the late 1950s, most of them funded by the
| various arms of the United States military, all of whom foresaw
| an unending appetite for ever-more-sophisticated electronics to
| control their weaponry and defense systems. The military-funded
| projects included "micro-modules" (individual components that
| would snap together like tinkertoys), "microcircuits" (wires
| and passive components etched onto a ceramic substrate into
| which active components, like transistors, could be connected),
| and "molecular electronics" (nanotechnology avant la
| lettre).[3]
