sm62704 (mcgrew) writes "The BBC is reporting that Israeli researchers have put the 300,000 word Hebrew Bible on a chip that is smaller than a pinhead.
"How many angels can dance on the head of a pin?" has been a rhetorical question for centuries, but has finally been answered. The answer is, of course, "all of them". At least all the ones in the Hebrew version."The 0.5sq-mm (0.01sq-in) nano-Bible was written on a silicon surface covered with a thin layer of gold (20nanometres thick — 0.0002mm).
It was written using a device called Focused Ion Beam (Fib).
"When we send the particle beam toward a point on the surface, the gold atoms bounce off of this point, thus exposing the silicon layer underneath," Ohad Zohar, one of the project's managers at Technion, said.
