Fluid Logic Chips
Doc Ruby writes "Colorado researchers 'have constructed microfluidic gates that use the relative flow resistance of liquid to carry out the basic logic operations NOT, AND, OR, XOR, NOR and NAND. The researchers have also combined a pair of gates into a half adder, which carries out half the operation of addition.' All CPUs processing binary logic are made of these types of gates, but usually execute as flows of electrons in wires, not fluids in tubes. Will this advance revolutionize chemistry and computing the way electric gates revolutionized electronics and computing? Will 'fluid programmers' give new meaning to "flowchart"?"
"The answer is that in this universe, no such infinitely rigid rod is possible"
No doubt that disappoints a lot of women, who were looking for an "infinitely rigid rod"... *rimshot*
