what i learned last week

1. all of the letters carried by the u.s. postal service is the equivalent of 5 pb (petabytes). (1 petabyte = 1000 terabytes) (1 terabyte = 1000 gigabytes)

2. google processes about 5 petabytes of data every 5 hours

3. until the introduction of the world wide web to the world, the number of people that read was in the decline due to television. since 1980, however, this number has tripled.

4. roughly 20% of surgical instruments are made in northern pakistan, where child labour is not uncommon. link
