" The power to guess the unseen from the seen, to trace the implications of things, to judge the whole piece by the pattern, the condition of feeling life in general so completely that you are well on your way to knowing any particular corner of it—this cluster of gifts may almost be said to constitute experience. "
Henry James

Demon Core Goes Critical

The Demon Core was a plutonium core—used in nuclear testing at the Los Alamos National Laboratory in New Mexico—so nicknamed because it resulted in the deaths of two scientists in separate accidents. In 1945, Harry Daghlian accidentally dropped a tungsten carbide brick onto the core, causing it to go "critical," or achieve a chain reaction of nuclear fission. Daghlian stopped the reaction, but died from radiation poisoning a month later. What happened to the second scientist nine months later?



Keystroke Logging

A keystroke logger is a program or device that captures every key struck on a keyboard, thereby creating a record of what has been typed. Software-based keystroke loggers can be installed clandestinely, via a computer virus or Trojan horse, allowing hackers to steal passwords and other confidential information. Some employers use keystroke loggers to track the computer use of employees, while governments use them to spy on suspected criminals. What countermeasures can defeat keystroke loggers?

One of the greatest offensive players in the history of basketball, "Wilt the Stilt" set many records and led the National Basketball Association in scoring every season from 1959 to 1965.
