pbahra writes "One complaint made of the modern stock market is that it is concerned too much on the short term. A second is a long time in cash-equities trading. Four or five years ago, trading firms started to talk of trading speeds in terms of milliseconds. But in recent weeks trading geeks have started to talk about picoseconds in what is a truly mind-boggling concept: a picosecond is one trillionth of a second. Put another way, a picosecond is to one second what one second is to 31,700 years."
