VIRGO (Aug. 23-Sept. 22): I rarely employ my mediumistic skills, but a host of spirits was just clamoring to address you this week. So I agreed to channel five of them, on the condition that they'd be brief and to the point. Here, then, are your advisors from the other side of the veil. First, Wernher von Braun: "Research is what you do when you don't know what you're doing." Second, A.A. Milne: "One of the advantages of being disorderly is that one is constantly making exciting discoveries." Next, Ralph Waldo Emerson: "Sometimes a scream is better than a thesis." Casey Stengel: "You're lost but you're making good time." Harry S. Truman: "If you can't convince 'em, confuse 'em."
