The best days of personal computer maker Dell Inc. may be behind it, financial weekly newspaper Barron's Inc. wrote in its November 7 edition. The paper noted that "Dell's revenue growth has now slowed for seven quarters in a row. If Dell's revenue fails to grow faster, and certainly if the company continues to miss earnings targets, it will be time to admit that Dell is past its best."
- "Growth has now slowed". That's the second derivative, folks - d2y/dx2. You see, the economic system we have is not only obsessed with growth, it demands an increasing *rate* of growth. The thing is, Nature has an equivalent for this kind of behaviour. We call it "cancer".
