Google's Silicon Supply
In very rough numbers:
Google employs about 65 million million transistors.
That's about ten thousands transistors for each man, woman, and child on this planet.
In the time it takes you to read this one sentence, Google will have completed about 8 million billion 32 bit operations in those transistors.
That's enough to calculate pi to the 200 thousandth digit for each person on this planet.
