دانلود کتاب ذهن هکرها – چگونه قوانین جامعه قدرتمند خم می شود و چگونه آنها را به عقب برگردانیم

A company called Uncle Milton Industries has been selling ant farms to children since 1956. The farms consist of two vertical sheets of clear plastic about a quarter inch apart, sealed at the sides, and with a top you can open up. The idea is that you fill the space with sand and put ants into the twodimensional environment. Then, you can watch them dig tunnels. The box doesn’t come with any ants. It would be hard to keep them alive while it sat on the store shelf, and there’s probably some child safety regulation about insects and toys. Instead, the box comes with a card where you can write your address, send it to the company, and receive back a tube of ants in the mail.
