Rumor (1): Increased solar activity at the end of 1999 could cause satellite systems to malfunction on or around January 1,2000.

Experts say that the next peak in solar flares or storms on the sun's surface, whice can interfere with normal satellite operations, will occur in late 1999 and early 2000; the last peak occurred in March 1989. It is believed that increased solar activity in May 1998 adversely affeted operations of the Galaxy 4 satellite over the United States, creating a few days of difficulties for pager operators and broadcasting companies.

Rumor (2): Y2K problems in federal prison facilities will cause cell doors and gates to open, increasing the risk of prison escapes.

Controls on doors and gates are always managed by correction officers, and the doors and gates do not operate on timers. Prison doors and gates are opened through human control, when the corrections officer pushes a button. In the event of power failures, the doors and gates default to a closed position.

Rumor (3): Organizations can experience Y2K-related glitches before January 1,2000.

Many businesses and government agencies have al ready reached, or will soon, a phase in their operations where they need to look a head into the Year 2000. These Took-ahead functions might include budget programming for a fiscal year that begins sometime after January 1,1999, or simple tasks such as making hotel or flight reservations. To the extent that the systems supporting such functions are not Y2K compliant, glitches could surface prior to the new millennium.

Rumor (4): Most elevator computers and embedded systems will fail on January 1, 2000. (...) If elevator systems were to experience Year 2000-related failures, all elevators have manual overrides that would enable them to return to operation.

Rumor (5): The Federal Aviation Administration (FAA), certain that the air traffic control system will not be ready at the turn of the century, will ground all flights in the United States at 6 p.m. on December 31, 1999, and not let any take off until 6 a.m. January 1, 2000.

The FAA has no plans to halt air traffic on or around December 31, 1999 !$ ± !$ Jan 1,2000. The FAA is committed to the safety of air transport and, as such, is working hard not only on its own systems, but with the airline industry, to ensure a seamless transition in to the new millennium.

'Debunking' Laissez Faire

My Atlantic Monthly essay, "The Capitalist Threat", has aroused the ire of Robert J. Samuelson ("Crackpot Prophet", JUDGMENT CALLS, March 10) for its perceived attack on the capitalist system. I wasn't attacking capitalism, only its excess and laissez faire ideology.

I pointed out a curious affinity between laissez faire ideology and Marxism: both lay claim to scientific validity. The Marxist claim has been fully discredited. But laissez faire ideology is derived from the most respectable of social sciences, economics, and its claim to scientific validity still requires debunking. I suspect that Samuelson prefers to dismiss my ideas as jumbled, rather than to entertain the possibility that the scientific foundtions of laissez faire are less than secure.

Our understanding of the world in which we live is inherently imperfect. This creates difficulties for the social sciences from which the natural sciences are exempt. Scientific method has discovered universally valid generalizations that can explain and predict events in the natural world. To make such generalizations possible, the events must be independent of statements that relate to them.

But in society, participants must make decisions about events that are contigent on their decisions. The separation between statements and facts, a characteristic of science, is lacking. (...)

Since nobody is in possession of the ultimate truth, we need institutions and attitudes that allow people with different views and interests to live together in peace. Markets are the best mechanisms for correcting individual errors, but government intervention and collective action are needed to protect common interests and correct inequities in the capitalist system. Laissez faire ideology - which holds that the common interest is best served when each individual pursues his own particular interest - is inadequate for holding our open society together.

My main contention in the Atlantic Monthly essay is that the concept of open society, which not only recognizes the multiplicity of cultures and traditions but actively advocates pluralism, could serve as a unifying principle for our global society.

The trouble is that the concept is neither recognized nor accepted.
