"In 1933, the Nazis chased Kahn out of Germany. His books were burned, banned, and put on the “list of damaging and undesirable writing.” Fortunately, enough of his illustrations survived to show us, among other things, how the human heart could move an elevator up five floors in 40 minutes, how dessert cleans the tongue, and how Mercury is so small that it could plunge into the Atlantic Ocean without touching the continents."
"Stuxnet's actual impact on the Iranian nuclear program is unclear, if only for the fact that no information is available on how many controllers were actually infected. Nevertheless, forensic analysis can tell us what the attackers intended to achieve, and how. I've spent the last three years conducting that analysis -- not just of the computer code, but of the physical characteristics of the plant environment that was attacked and of the process that this nuclear plant operates. What I've found is that the full picture, which includes the first and lesser-known Stuxnet variant, invites a re-evaluation of the attack. It turns out that it was far more dangerous than the cyberweapon that is now lodged in the public's imagination."
